< Back Nasogastric Tubes Nasogastric tubes (NGTs) are frequently placed in surgical patients to decompress the stomach and minimize nausea/ vomiting while allowing bowel rest. For intubated ICU patients, this is frequently an orogastric tube, passed from the mouth to the stomach. The anatomy of an NGT Lumen: this is the inner cylindrical hollow conduit that allows gastric contents to be suctioned out and potentially allows medication and nutrition to be given (depending on the clinical situation). Multiple holes to allow gastric contents to be suctioned into the lumen of the tube Side port: if nasogastric tubes were like straws, with only one lumen, they would adhere tightly to the stomach wall when suction was applied. Thankfully, NG tubes have a side port (the blue ventilation port) that allows air to flow into the stomach, preventing the tube from giving the stomach a suction hickey. Markings on the tube indicate how far the tube has been inserted. A white line along the length of the tube (radiopaque). When viewed on an x-ray, the tube position can be confirmed by noting the location of the break in the radio-opaque line, which corresponds with the most proximal hole in the tube. Basic Equipment There is some basic equipment that you need to have at the bedside before inserting an NGT The NG tube and a packet of lubricant A large basin (in case the patient vomits) Suction tubing to connect to a canister with working suction Cup of water with straw (if not contraindicated) Placement Preparation Picking your tube size. Tubes range from 8-18 French. For adults, use 16 or 18. Avoid using a pediatric tube or anything smaller than a 16 Fr. Small tubes will just end up clogged. You can consider having one size smaller just in case you meet a lot of resistance and want to attempt a smaller caliber. Running the tube underwater. Some suggest that warm water helps by making the tube more pliable, others say cold water helps by making the tube softer. I haven't found one to be more helpful than the other. Try and see what works for you. Explain the procedure to the patient. Advise them that they might gag and vomit, and that’s ok. It’s not unexpected when you have a plastic tube through your nose and esophagus. Have the basin ready. Tell the patient their job is to swallow and keep swallowing. Tell them they might feel an urge to cough or gag, but they should try to resist that and focus on swallowing. If not contraindicated (ie aspiration risk, etc), have the patient hold a cup of water (with straw) in the hand opposite from where you're standing. Note- bowel obstruction is not a contraindication- once you place the tube, you will evacuate whatever the patient swallowed. Positioning and insertion Raise the head of the bed and have the patient upright as much as possible and have them put their chin to their chest. Lubricate the end of the tube. Place the tip of the tube just inside the nares and then advance parallel to the floor…not up. You can place your hand on the back of the patient's head to gently keep their head from flying back, which is the natural reaction to a huge piece of plastic in your nose. Keep advancing the tube while encouraging the patient to swallow. The gastroesophageal (GE) junction is usually about 40 cm from the beginning of the esophagus. The tube must get past the GE junction to effectively decompress the stomach. Post-placement Connect your tube to suction. There is a small plastic connector with tapered ends- one end connects to the suction tubing and the other end connects to the clear port. You can place to low intermittent or continuous suction- this is usually provider or institution dependent. You do NOT need a chest x-ray to confirm that an NGT is in the stomach before you place it to suction- if gastric contents are being suctioned, this confirms the position. You DO need a radiograph before instilling medication or enteral feeds. Risks of nasogastric tubes Non-functional tube- an NGT is nothing more than a straw or a garden hose- except for one thing. If you were to place a garden hose into someone's stomach and apply suction, it would just adhere to the stomach wall. This can lead to suction hickeys, which are precursors to ulcers/ bleeding. But most importantly, this will cause the tube to be ineffective. The solution is the blue ventilation port- it allows air to pass into the stomach and keeps the tube from being suctioned against the stomach wall. [this was explained above in the anatomy section- but it's so important that it deserves repetition] Naso-pulmonary tube- accidental insertion into the lung. For an awake interactive patient, this will be evident by your patient's reaction- if they have a tube in their lung, they will cough. This can even cause a pneumothorax (personally never seen it, but it's been described). In an intubated patient, it might not be noticed until x-ray for checking placement. Tube curled and tip directed upward in the esophagus. Two risks- ineffective gastric decompression and misdirected meds and feeds (back up in esophagus instead of into stomach). Aspiration- an NGT essentially stents the lower esophageal sphincter open. So if your patient is lying flat (ie asleep), you MUST ensure that the NGT is functional. Especially in the case of a bowel obstruction (patient can vomit and aspirate) or if your patient has decreased mobility and isn’t able to reposition themselves quickly to avoid aspirating. Clogged tube- risk of aspiration, inability to give meds/ enteral nutrition. The anti-reflux valve You might notice another piece of plastic in the NGT packaging. I didn't mention the anti-reflux valve, that short blue and white plastic piece that suspiciously seems to fit perfectly into the blue ventilation port. According to the manufacturer (CR Bard), this piece of plastic is supposed to be inserted at the end of the blue port and allow air entrainment to prevent the suction hickey on the stomach. It also prevents gastric contents that reflux into the port from spilling onto the sheets. HOWEVER-- the caveat is that when gastric contents are refluxing into the blue ventilation port, it's supposed to be take as an indicator that the valve must be removed and air must be flushed into the blue ventilation port. This is the reason the anti-reflux valves are despised by most surgeons- once the blue ventilation port is coated with gastric contents, if they're not flushed, the NGT is essentially converted to a straw. Yes, the port may spit up some gastric contents. However, the solution is NOT to replace the anti-reflux valve into the blue side port. Instead, the solution is to flush air into the blue port to clear it out . This is the primary task of maintaining a functional tube. You should hear faint sounds of air movement when you listen to the blue port- this means it’s working! [see video] The problem, and the reason we routinely throw these away, is the fact that they aren’t routinely removed and flushed, so they get clogged. When the blue port is clogged, the tube becomes non-functional, which can lead to gastric distension, nausea/ vomiting, and aspiration. “Minimal output” is not always reassuring with an NGT- it might be because the patient is improving, but it’s just as likely that the tube isn’t working because it isn't being maintained correctly. It's not an exaggeration to say this is a life or death issue. An elderly patient with a bowel obstruction and a non-functional tube→ gastric distention + widely patent gastroesophageal junction + laying flat at night→ aspiration, pneumonia, death. Functional tubes are also crucial for patients with foregut procedures. For example, a repair of a stomach or proximal small bowel injury can be protected by a functional nasogastric tube- this minimizes air/ fluid passing by and exerting pressure on the repair. Please note- the blue ventilation port MAY reflux and spill out gastric contents. Two solutions are to place a chux under the end or to place the syringe of a Toomey at the end (see video). Just remember- if this happens, do NOT solve the problem by inserting the anti-reflux valve. Instead, use a Toomey syringe to flush air into the blue ventilation port. CAUTION! There are caveats to this- specifically patients with foregut surgery (anywhere from the mouth through the first part of the small intestine). Patients with these clinical scenarios should have explicit instructions to the nursing staff on how the tubes are to be maintained. But it makes too much noise?! A patient who can complain about a whistling NGT is a patient who is much less likely like to aspirate and need to be intubated than a patient who doesn't have a whistling NGT. But it makes a mess?! See solutions above- chux pad or place a Toomey syringe. How to maintain a functional NGT https://video.wixstatic.com/video/3b6ff6_0ae99743e4244ce6a94c3c6bdd532efd/1080p/mp4/file.mp4 How to use the anti-reflux valve https://video.wixstatic.com/video/3b6ff6_346b85a924454960bd6c4afe6ab037d0/1080p/mp4/file.mp4 So those are the basics. If I didn’t teach you any handy tricks, hold on for one last disclosure… the final secret to my success. I've used this trick many times for patients who are overly anxious or distressed at the process of having an NGT placed. For example, the patient who has had traumatic NGT placements previously (patients have shared so many horror stories with me) or is on edge in general. Two years ago, I was managing a burn patient in the ED. While the ED physician was prepping for a nasal laryngoscopy, he showed me a trick that I still use to this day. Using CTAs (cotton tip applicators, or Q-tips if you insist on a brand name), he anesthetized the patient's nasal passage with viscous lidocaine. He covered the cotton tip of 1-2 CTAs with the clear hair-gel consistency goop (the lidocaine), and then slowly advanced this along the nasal passage. Initially, they sat right inside the opening of the nares, resting for maybe 30-45 seconds. Then the lidocaine was reapplied, and the CTAs were advanced slightly to repeat the process. This continued through the entire length of the nasal passage. In addition to the nasal anesthetic, the patient was given a medicine cup with more viscous lidocaine to swallow. *Note- warn the patient that they MIGHT get the sensation that they can't breathe. They will still be able to breathe fine, but when the upper airway is anesthetized, it alters the sensation of airflow. Previous Next

< Back Getting Involved Getting involved in your training program and hospital is crucial for your professional development and growth. Here are some tips to help you get started. - Be open to opportunities to get involved early and embrace small projects. Even if a project seems insignificant, it can lead to bigger opportunities. Don't hesitate to accept requests to help write a paper, design a research protocol, or participate in a committee. These small projects can open doors for more significant roles and responsibilities in the future. - Be proactive and take the initiative to get involved. Talk to your mentors and program directors about your interest in participating in projects or committees. Ask for guidance on how to get involved, and don't be afraid to express your interest in specific areas. - Get involved in research. You don’t have to have a strong research background to contribute to ongoing projects. If you have specific research interests, seek the advice of someone with a similar interest and collaborate with them. Different faculty members will have their individual strengths and passions, which are frequently apparent after you interact with them. If you partner up with someone who has a similar interest, they will be able to guide you and lend their support to your project. Training programs frequently have requirements for research and have a framework for supporting involvement in ongoing projects. Research requirements are often a part of training programs, so take advantage of the support and resources available to you. Also, keep in mind that there may be ongoing research projects at your hospital that you can contribute to. - Attend department and hospital level conferences. Grand rounds, morbidity and mortality (M&M) and case conferences are invaluable learning opportunities. Conferences that review complications or deaths are invaluable learning opportunities. They are also a good platform for developing performance improvement projects. Many patient incidents are multifactorial, and there are frequently systems issues that can be addressed to minimize repeat events. - Join committees. Committees are a great way to learn about the inner workings of the hospital and contribute to important decision-making processes. They also provide a venue to meet colleagues in other departments and gain valuable networking experience. - Talk to people. Reach out to your mentors, program directors, and research staff about other opportunities that may be available. They can often provide valuable insight and connections that can lead to new opportunities and projects. After you have explored the opportunities to get involved in your program and hospital, it’s time to widen your professional network. Expanding beyond your hospital will help you stay current with industry trends, discover new opportunities, and establish relationships with colleagues and mentors. One way to do this is by participating in surgical organizations at the national level. Here are some examples: - American College of Surgeons (ACS). The ACS offers membership and participation opportunities starting in medical school. As a member, you can take advantage of educational programs, networking events, and leadership development opportunities. Fellowship in the ACS (FACS) requires board certification, and it is a prestigious recognition that can enhance your professional reputation. - American Association for the Surgery of Trauma (AAST). AAST is the premier national organization for the field of acute care surgery (trauma, surgical critical care and emergency general surgery). There are numerous opportunities for involvement in research and professional development. Membership requires FACS status. However, the organization recently added an associate membership category, which offers younger surgeons an opportunity to participate in the AAST's activities and programs. - The Eastern Association for the Surgery of Trauma (EAST). EAST provides leadership and development opportunities for young surgeons who are actively involved in the care of injured patients. The organization offers ample opportunities to get involved in committees, research projects, mentorship, and leadership roles. This is far from an exhaustive list, but it is a good starting point for young surgeons to explore how they want to develop their network. During my Acute Care Surgery fellowship, I was able to get involved in various research projects and initiatives that allowed me to further develop my expertise and knowledge in the field. At the start of my fellowship, I developed a research protocol that evaluated the impact of legislation on the opiate epidemic. This project allowed me to delve into a critical issue facing the healthcare industry and explore potential solutions to mitigate the epidemic's impact. Shortly after, I attended a department committee that updated our clinical practice guidelines. As we discussed some recent patients with rib fractures, I saw the importance of updating our thoracic trauma management guidelines. I partnered with one of the faculty who had a particular focus on rib fracture management and we worked to optimize our protocol for caring for these patients. This led to multiple opportunities, including an IRB protocol and two manuscript submissions on operative rib fixation. I also had the opportunity to co-author a book chapter on Intensive Care Unit (ICU) management of blunt chest trauma and a manuscript on the use of opiates in chest trauma. During a meeting with one of the research directors in our department, I was able to learn about opportunities to get involved in ongoing projects. This led to me joining a group working on coagulopathy in traumatic brain injury. Through this project, I was able to contribute to a literature review submission and co-author a research manuscript submission. I was also able to present our findings at a national conference. My program director was a strong supporter of and actively shared news about opportunities that could further my career development. One of these opportunities included writing an essay that allowed me to publish and present at a conference. After reading my essay, a critical care physician reached out to connect and invited me to participate in testing a tool for resuscitation in austere environments. This was a unique opportunity that allowed me to apply my knowledge and skills in a new and challenging setting. Overall, my Acute Care Surgery fellowship allowed me to explore different avenues in research and develop expertise in areas that I am passionate about. It also enabled me to collaborate with other experts in the field, broaden my network, and gain invaluable experiences that served me well in my future career endeavors. Previous Next

< Back Shot in the Chest- Aortic Occlusion A 30-year-old male sustained a gunshot wound to his left lower chest/ upper abdomen. On arrival, his heart rate was in the 50s with weakly palpable carotid and femoral pulses. Significantly hypotensive. Penetrating wound to the left lower chest wall with an occlusive dressing in place without ongoing hemorrhage. Initial workup and management? Assess mental status. Secure large-bore peripheral IV access and start massive transfusion. A rapid ultrasound of the chest and abdomen revealed fluid in the left chest, right upper quadrant, and no pericardial fluid. We placed a left chest tube with minimal output. Still hypotensive…treatment options? Resuscitative thoracotomy. Urgent OR if vitals improve with resuscitation. REBOA. A rapid secondary survey revealed a previous midline laparotomy. This would likely impede rapid access for aortic control during laparotomy, so REBOA was placed through a right femoral artery cutdown. With inflation of the REBOA, he had a return of cerebral perfusion with spontaneous movement of his extremities. He was transported emergently to the OR. We encountered massive hemoperitoneum and extensive dense intra-abdominal adhesions that prohibited easy access for a supra-celiac aortic clamp. There was ongoing hemorrhage despite REBOA. Other options to control intra-abdominal bleeding? Procedures directed at source (compression of the liver, splenectomy, etc). Aortic occlusion above the injury- stops all perfusion below the level of occlusion. This can be done from the chest through a left anterolateral thoracotomy or below the diaphragm (supra-celiac clamp). The patient underwent left thoracotomy for aortic cross-clamp. There were no obvious intra-thoracic injuries. Intra-abdominal injuries included a large Zone 1 retroperitoneal hematoma and left diaphragm injury, injuries to solid organs (liver and pancreas) and hollow viscus (stomach, small bowel, and colon). Management of massive sub-diaphragmatic hemorrhage Aortic occlusion decreases distal bleeding and redistributes blood volume to the myocardium and brain. This leads to a reduction in sub-diaphragmatic blood loss. Traditionally, this is accomplished through an open approach, either via thoracotomy or laparotomy. Concurrent with the expanding use of and comfort with endovascular approaches, endovascular occlusion of the aorta (REBOA) has been re-introduced as a less invasive approach. General indications Traumatic life-threatening hemorrhage below the diaphragm (non-compressible torso trauma) in patients in unresponsive shock Zone 1 (distal thoracic aorta)- control of severe intra-abdominal/ retroperitoneal hemorrhage, or for traumatic arrest. Zone 3 (above aortic bifurcation)- severe pelvic, junctional, or proximal lower extremity hemorrhage. Mixed results regarding clinical outcomes. Essentially the same time to aortic occlusion as resuscitative thoracotomy. Not shown to be significantly quicker at obtaining aortic occlusion than resuscitative thoracotomy. Brenner M et al.

< Back Career Management 1. Create and maintain a curriculum vitae (Microsoft Word template below) that will serve as a comprehensive record of your professional and personal accomplishments. Keep this document up to date by adding new entries as they occur. Include details of your awards, training, leadership positions, committee participation, speaking engagements, and volunteer experiences. Also, list your non-professional talents, such as athletics, foreign language proficiency, and musical abilities. This will help you keep track of your achievements and provide a ready source of information when you need to update your CV. It is recommended to have a master document that includes everything, and you can tailor it to each submission. 2. Develop a personal database to store important documents, such as school transcripts, exam results, awards, training certificates, etc. Organize them in a manner that is easy to access when needed. For hard copies, use a 3-ring binder with clear sheet protectors. For digital copies, create designated folders on your computer. Name each file to in a way that your database is easy to organize and easy to search. This will help you avoid scrambling to locate essential documents when someone requests them. Do not rely on external databases to maintain your documents. Instead, download copies of important records. Create digital copies of important email conversations (scheduling rotations, arranging research projects, agreements, etc). 3. Keep templates of commonly created forms, such as requests for letters of recommendation or sponsorship , personal statements, etc. This will save you time and effort by allowing you to work from a prior document instead of starting from scratch each time. Request LOR Template .docx Download DOCX • 42KB Request Sponsorship Template .docx Download DOCX • 42KB 4. Establish and maintain relationships with trusted advisors who can review your written work, ranging from formal email messages to research papers. Choose someone with expertise in your field as well as someone who has strong spelling and grammar skills. Seek someone who will provide constructive feedback instead of blind positive support. By following these tips, you can build a strong foundation for your medical career and increase your chances of success. Remember, although mentors, friends, and family members can offer sound advice, ultimately, you are the best person to manage your medical training and career. Previous Next

< Back Pruritis Ani What is Pruritis Ani? Patient information: Pruritis Ani [American College of Colon and Rectal Surgeons] Pruritis ani is an unpleasant itching of the perianal skin (around the anus). Scratching can lead to further irritation and sets up a vicious cycle. Caused by other anorectal diseases, primary dermatology conditions, hygiene issues (sweat, stool, mucus on the skin), foods, soaps, clothing, or over-vigorous hygiene (aggressive wiping with rough material, use of topical cleaning agents). Diagnosis- detailed history, thorough exam to rule out underlying anorectal pathology What is conservative management for pruritis ani? Try not to scratch/ wipe/ scrub. It will just itch more, and things will get worse. Clean the anal area after bowel movements with hypoallergenic personal wipes. Do NOT over clean, as this may worsen your condition. Dry with a hairdryer on the cool setting instead of wiping the area dry. Use unscented Dove soap or dilute white vinegar for cleansing. AVOID potential contributing factors Citrus foods, caffeine-containing foods/ beverages- coffee, tea, cola, chocolate. Scented soaps, lotions, creams, powders, medicated wipes, witch hazel. Keep the area dry (can use cotton ball or a gauze pad). Avoid tight synthetic clothing that doesn’t breathe. Wear cotton undergarments. Maintain regular bowel movement with normal consistency (minimize stool leakage). Increase stool bulk by increasing fiber intake. Maintain adequate hydration- you MUST drink at least 64 ounces of fluid per day, in addition to increasing fiber intake. Medication Capsaicin- causes a low-grade burning sensation and decreases the perception of itching Zinc oxide- Apply a small amount of a barrier cream to the perianal skin in a thin layer. This will protect the skin from irritants. Mix Benadryl cream with the zinc oxide cream and apply it to the affected area.

< Back Respiratory Failure- it hurts to breathe A 47-year-old male sustains multiple traumatic injuries after being struck by a vehicle while on the side of the road. He had severe thoracic trauma (bilateral pulmonary contusions), bilateral femur fractures and a liver laceration. He also had a severe TBI, requring intubation shortly after his arrival. 10 days into his hospital stay, he still requires ventilatory support. What are some of the potential causes of the patients ongoing requirement for mechanical ventilatory support? Pain from rib fractures, pneumonia, ARDS, pulmonary embolism, fat embolism, pulmonary contusions, loss of chest wall stability due to severe thoracic trauma, hypomagnesemia, volume overload, retained hemothorax, poor nutrition from inadequate protein delivery. He is undergoing a trial of spontaneous ventilation, but he develops tachypnea and hypoxemia and appears to be struggling on the ventilator. What are some of the initial steps in evaluating this patient? Physical exam (pulmonary exam, assess for edema), bedside ultrasound (pleural effusion, pneumothorax). Chest x-ray- look for infiltrates. ABG, EKG, review volume status. His chest x-ray is shown below. What do you see? Trachea midline, no effusions. Bilateral fluffy infiltrates. His current ventilator settings and ABG results are shown below. Ventilator settings: RR 12, TV 450, PEEP 10, FiO2 50. Arterial blood gas: pH 7.34, PaCO2 42, PaO2 64, HCO3 24 What does this tell you about his oxygenation? PaO2:FiO2 ratio is an indicator of oxygenation. This patients P:F ratio is 182. See below for explanation. What diagnosis is this consistent with? Acute respiratory distress syndrome. What are the management principles when caring for a patient with ARDS? What are your initial ventilator management strategies? ARDS is not a primary diagnosis, so it is important to treat the underlying cause (pancreatitis, pneumonia, etc). Minimize further insults to the lungs. Optimize ventilator strategies- low tidal volume, target PEEP/FiO2 combination to target SpO2 88-95% Diagnosis and Management of ARDS Etiologies of ARDS Pneumonia, pulmonary contusions, aspiration, inhalation Trauma, burn Pancreatitis Transfusion-related acute lung injury (TRALI) ARDS diagnostic criteria: The Berlin Definition [1] Onset of respiratory failure within 1 week of an insult that is known to cause ARDS Bilateral fluffy infiltrates on CXR not explained by effusions/ infiltrates/ contusions/ lung collapse Respiratory failure not related to heart failure or fluid overload Oxygenation PaO2/FiO2 ratio with PEEP ≥5 cm H2O.

What language are we speaking? Speaking Greek < Back What language are we speaking? Medicine has a language all its own. Sometimes we use formal words for common terms, like sputum or phlegm to refer to snot. But a lot of words are unique to the medical field. When speaking with patients and families, the most important thing is communicating effectively. Using a slew of foreign and formal words might sound impressive, but everyone will likely be more confused when you leave the room. After years of education and training, words and phrases in the medical dictionary become second nature. Our conversations with colleagues, consultants, and peers are frequently saturated with this unique lexicon. Sometimes this even spills into your conversations outside of work, and your family and friends might start to pick up some of your common work terms. Patients and their families are not fluent in the language of healthcare unless they are employed in healthcare or have experienced frequent interactions with the healthcare field, such as being a caregiver for an ill family member or suffering from a chronic illness. Once you learn something, it’s difficult to remember a time when you didn’t know. If you’ve worked in healthcare, it’s obvious that laparoscopic cholecystectomy means using tiny incisions and long instruments to remove the gallbladder through the belly button. But unless you’ve had one yourself or know someone who has had one, these words might have little meaning. This language barrier can be even more challenging in the stressful environment encountered in the ICU. Several factors create additional barriers to effective communication. 1. Patients in the ICU are sicker and the threat of death or serious disability is more apparent. This can create emotional distress that occupies or distracts families as they try to ask questions and get answers, impairing their ability to thoroughly understand, even if the healthcare team provides very detailed, comprehensive information. 2. When individuals receive bad news, they process/ remember very little after the initial shocking revelation. 3. The higher acuity and sometimes the need for urgent intervention can add time constraints. This creates an additional barrier to effective communication- having to convey the information and potentially obtain consent for treatment and procedures while balancing the ever-present demands of multiple urgent procedures and critical patients to attend to. Families can get information from different members of the healthcare team. Sometimes the nature of the conversation demands the skills of the most experienced provider. However, young trainees sometimes converse with families as well. It’s easy to forget the process of learning how to effectively communicate with families in difficult situations. Listening to phone conversations between team members and family can be enlightening. As young trainees are becoming much more facile with the unique language of the ICU, it can start to infiltrate these discussions. For example, imagine you are caring for a patient who was just admitted to the ICU with a severe traumatic brain injury. When you’re reporting to the accepting team, you’ll use words like subdural hematoma, midline shift, cerebral edema, and severe TBI. When discussing the patient's current clinical status, you might mention that they are over-breathing the ventilator or that they don’t have brainstem reflexes. When developing a management plan, you might discuss the utility of ICP monitoring and debate the use of a bolt or an EVD, the benefits of hypertonic saline versus mannitol for hyperosmolar therapy, whether or not to hyperventilate the patient and the potential for a craniectomy. While these will be readily understood by your colleagues, these are likely foreign terms for most family members. So here are some tips for talking to family and friends, especially during initial conversations. 1. Avoid unfamiliar medical terminology (for example: severe TBI, hypertonic saline). Instead, opt for descriptors such as “bad head injury” or “medication to protect the brain”. 2. Avoid unnecessary details. Don’t ramble on about everything that has happened, especially while they are waiting to hear if their loved one is alive or dead.

Pros test the doneness of muffins, quick breads and cakes by simply inserting a toothpick. If it comes out clean, they are ready to cool. Biscuit 3:2:1 flour:liquid:fat Baker Move: Pros always scoop flour, sugar or other dry ingredient into a measuring cup, then use the back of a knife or other straight edge to level it off. Vinaigrette 3:1 oil to vinegar. Add herbs, garlic, or mustard to elevate your dressing Cookies 3:2:1 flour:butter:sugar Other ingredients like eggs, baking powder, and flavourings can be added, but the core 3:2:1 ratio for the main dry, fat, and sweet components is the foundation. Baker Move: Using a dough scoop (like a small ice cream scoop) to portion equal-size cookies adds a professional touch to your finished cookie plate. Pound Cake 1:1:1:1 flour: egg: fat (unsalted butter): sugar Baker Move: Pull your butter and eggs out of the fridge a couple of hours before you're ready to bake. Room-temperature butter is better for creaming, and you'll want the eggs at the same temperature to prevent them from seizing.

Meringue 2 parts sugar: 1 part egg whites or 1 part sugar: 1 part egg yolks Baker Move: Avoid cracks in your perfectly piped meringues by keeping your oven door closed while they dry out.

Drop too many in the frying oil at once and the temperature will plummet, producing a greasy, mushy fritter. Custard 2:1 eggs:liquid Baker Move: Once you have that ratio down, remember to strain your cooked custard through a fine mesh sieve to remove any lumps. Crepes 1/2:1:1 flour:liquid:egg Baker Move: Crepe batter needs time to set up, preferably overnight in the fridge. Links Cooking with Ratios Food Network Previous Next
