Give me that thing that does the thing… Kelly Snap Mosquito < Back Give me that thing that does the thing… I don’t remember the names of all the instruments in the surgical tray. I swear they have a unique name for each size of the same instrument. Hemostats- crile, snap, stat, mosquito, tonsil, Kelly, Rochester Pean. There is a laundry list of pickups of different shapes with different teeth. And then throw in the culture of different hospitals and specialties. When you place a Bookwalter and you want the short wide curved retractor…do you call it a bladder blade or a curved body wall? And the straight one…is that a Rich or a body wall? In case you’re wondering, the curved retractor is called a Balfour and the straight retractor is called a Kelly. When you’re doing a laparoscopic cholecystectomy, do you ever ask for a wavy grasper or do you call it a prestige? Or something else altogether? As I resident and attending, I used a wavy grasper . Check out the picture. Doesn’t it look like…a wavy? When I was in fellowship, the same instrument was called a prestige. Sounds unnecessarily boastful to me, but whatever. After 9 years using a wavy, it was hard to break the habit and call it a prestige. Thankfully, the scrubs knew what I wanted. I found out it's actually called a Prestige Style Atraumatic Wavy Grasper , so it turns out, we are both right. But that would take way too long to say each time you want to grasp the infundibulum. As we move through training, we develop routines, including our favorite instruments to use during different steps of the operation. When surgeons and scrub techs spend time together during cases, they frequently develop a rhythm, a shorthand. A good scrub tech knows what you want before you even ask. I have had the fortunate of developing several relationships like this. My favorite scrub tech was Kelly. She was a fantastic tech, but also a fantastic person. And the joke of asking for Kelly Kelly never got old. After years of working together, she understood my style and my technique, and always had my next instrument ready. To be honest, it didn’t take years. She knew what I wanted, even if I asked for the wrong thing. She was an invaluable asset to the team, and I miss working in the OR with her. As I mentioned, I don’t remember the names of all the instruments in the surgical tray. A good scrub tech gives you what you want, not what you ask for. While operating, I often extend my hand toward my scrub tech, and as I’m trying to come up with the right name, I start to make gestures with my fingers. Fingers posed like holding a pencil signals scalpel. Thumb and index finger pinched together is my gesture for pickups. Index and middle finger in an open/close motion indicate scissors. Curved fingers, like holding a cup, means I want a retractor. And I request a needle driver by holding the scalpel pose and moving my wrist through a suturing motion. There have been many innovations brought about by the COVID pandemic, and I predict that business will never be conducted the same as before this era. The protective gear worn to prevent viral transmission negatively impacts team communication. This was one of the summary findings of a survey of surgeons, recently published in the World Journal of Surgery.(1) The impact on speech discrimination has been quantified in an experiment with a simulated noisy background.(2) Google “communication impediment COVID protective equipment” and you will encounter many publications regarding the unintended consequences of interventions designed to keep health care personnel safer. Before the pandemic, we already operated wearing masks, which eliminates some of the visual cues of communication. But novel respirators can add several hindrances, including restricting normal jaw movement and muffling the spoken word. The use of the PAPR (powered air-purifying respirator) added a whole new dimension- noise from the fan and battery adds a remarkable hurdle when the surgical team is trying to communicate with other members of the operating team. Admittedly my system is imperfect, and I think a universal sign language for the operating room is a brilliant concept. A proposed system was recently published in the British Journal of Surgery.(3) Signals were developed to request a scalpel, various retractors, forceps, needle drivers, and gauze. This concept is logical, although admittedly, I have become increasingly reticent to accept any innovation just because it appears simple and absent of downsides. Consider the intubation boxes that were developed to prevent aerosol dissemination early in the pandemic. The concept was rational- solid barrier to isolate the patient, great idea! But during simulation, there were multiple hurdles- largely, it makes difficult intubation more challenging, which potentially defeats the purpose by increasing maneuvers and personnel and time to successful intubation. To quote one review: “Well-designed simulations…should always be used to test medical innovations before implementation... “Face validity” alone should not be the basis of innovation adoption.”(4) Is a new language necessary? Do we really need a system to talk to the tech, who is standing closer to us than anyone else in the room, and probably already knows what we want? They are more focused on exactly what is going on in the operative field than anyone else, and they can lean closer or ask us to repeat our request. We need a better way to talk to everyone else in the room! The anesthesiologist who is balancing multiple tasks and the OR nurse who is at least several steps away from the surgeon. What are the potential roadblocks or negative consequences associated with implementation? · Potential for misinterpretation of signals…someone is expecting a pickup and they’re handed a scalpel, which is quickly brought into the field and creates an injury. · The inability of the surgeon to create the signal if both hands are working. · If verbal communication is eliminated, the tech has to constantly watch the surgeons hands, which prevents them from doing other manual tasks, such as loading clip appliers, returning needles to the count box, receiving freshly opened materials from the scrub nurse, etc After all that, I’m not rendering a final verdict. This is an innovative and intriguing concept with a lot of potential. It should be considered and trialed while ensuring that its benefits outweigh the negative impacts before wide-spread implementation. 1. Yánez Benítez C et al.

< Back Vent Mgmt #2: Modes Mandatory Breaths Volume control (volume limited)- set TV and flow, pressure and inspiratory time are the dependent variables. Pressure control (pressure limited)- set inspiratory pressure and inspiratory time, volume and flow are the dependent variables. What is the downside of VC and PC? You can only control one parameter, and the dependent variable varies based on the patient's lung mechanics. For a patient on VC, if their lungs become less compliant, delivering the same tidal volume will generate higher pressure, increasing the risk of barotrauma. For a patient on PC, if their lungs become less compliant, the target pressure will be reached at a lower volume, so there is a risk of decreased ventilation (↑PaCO2). Pressure-regulated volume control (PRVC) is a hybrid mode that attempts to overcome this limitation. The target volume is delivered at the lowest possible inspiratory pressure by assessing the delivered tidal volume at the inspiratory pressure during each breath. What about inverse ratio (IR, IRV-PC) ? Increasing the inspiratory time relative to expiratory time increases mean airway pressure. This can be accomplished with pressure-controlled modes, where inspiratory time can be prolonged (normal ratio 1:2, IRV is when inspiratory time is greater than expiratory time). As discussed, MAP affects the surface available for oxygen exchange. This is why IR can be used to optimize oxygenation. Mandatory and Spontaneous Breaths Synchronized intermittent mandatory ventilation (SIMV)- a variation on VC or PC. The machine delivers mandatory breaths, but the patient can also control spontaneous breaths in between the mandatory breaths. Spontaneous Breaths Pressure support- spontaneous mode, the patient initiates breath, the ventilator provides support to overcome the resistance of breathing through the endotracheal tube, flow is adjusted to maintain the inspiratory pressure. The support is terminated when the flow decreases to <25% of peak flow. The patient controls duration and volume. *This is also a setting that can be adjusted in SIMV for assisting spontaneous breaths between ventilator breaths. Airway Pressure Release Ventilation (APRV)- invasive form of ventilation with BiPAP. The patient breaths spontaneously, alternating between a sustained time (time-high) at a set pressure (pressure-high) with a very brief release (time-low) of pressure (pressure low) to allow expiration. The goal is to maintain a higher MAP to optimize oxygenation. Previous Next

< Back Intracranial Hypertension A 32-year-old male was an unhelmeted motorcyclist who was struck by a car and throw 20 feet. He had decreased alertness on the scene and was urgently transported to the hospital. On arrival to the ED, his GCS was 7 (E2V2M3). He was hemodynamically normal and secondary survey was only remarkable for diffuse road rash and a large scalp laceration. He was intubated for concern for inadequate airway protection. Chest x-ray revealed multiple left sided rib fractures, FAST was positive in the right upper quadrant and the pelvis x-ray was unremarkable. He was taken to the CT scanner for head, c-spine, chest, abdomen and pelvis imaging. He was transported to the trauma ICU as his images were reviewed. Head CT Case courtesy of Derek Smith. From the case rID: 169704. Imaging revealed a large right sided subdural hematoma. He has left lower rib fractures and a grade 3 splenic injury. Neurosurgery evaluated him upon arrival to the ICU. How is intracranial pressure monitored? The preferred method for ICP monitoring is with an external ventricular drain. This allows the dual function of monitoring ICP as well as allowing to treatment of elevated ICP via drainage of cerebrospinal fluid (CSF). What is a normal value for ICP? Normal ICP is <20 mmHg and treatment is recommended for sustained ICP >22 mmHg. Neurosurgery places an external ventricular drain. His opening pressure was 32, and his ICP ranges from 25-32 over the next few hours. He was in reverse Trendelenburg, and he was adequately sedated. His repeat head CT was unchanged. He had CSF drainage via his EVD. He was given 2 boluses of hypertonic saline. His ICPs improved, and were sustained at 18-20 mmHg. He develops hypotension, with systolic pressures in the 80s. What are some of the possible etiologies for hypotension, and how would you evaluate/ treat the various etiologies? Bleeding from his spleen→ urgent splenectomy. Hypotension is detrimental to TBI. Side effects from sedation medication→ decrease dosages or switch therapeutic agents, implement other treatment strategies Evaluation and Management of Traumatic Brain Injury The goal of the initial management of TBI is the prevention of secondary brain injury. Avoid hypotension and hypoxemia Target normal pulse oximetry, normal PaCO2 (35-45 mmHg) and PaO2 (≥100 mmHg), normal blood pressure (SBP ≥100), normal electrolytes, normal temperature, platelets >75K, hemoglobin >7 g/dL.[1] Treat pain and provide sedation as appropriate. Optimize patient positioning to promote cerebral venous drainage- elevate the head of the bed and ensure the cervical collar or endotracheal tube support is not too tight. Monro-Kellie Doctrine[2] Inside the bony skull, there is brain tissue, blood and cerebrospinal fluid. Increase in any one of these (tumor, hemorrhage, edema) requires a compensatory decrease in one of the other substances in order to maintain normal intracranial pressure (ICP). ICP rises when compensatory mechanisms fail. Elevated ICP leads to decreased cerebral perfusion pressure (CPP). CPP is the difference between mean arterial pressure and intracranial pressure, and serves as an additional measure of adequacy of cerebral perfusion [CPP= MAP – ICP]. This is similar to the concept of abdominal compartment syndrome- when intraabdominal pressure increases above a threshold, there is decreased organ perfusion. Initially, the brain is able to autoregulate and maintain cerebral blood flow (CBF) across a narrow range of CPP, but this compensation is also limited, and CBF decreases as CPP falls. The general target for CPP is ≥60 mmHg, but note that this may vary if cerebral blood flow autoregulation is impaired. Monitoring intracranial pressure (ICP) is not independently associated with improved outcomes. It does not replace serial neurologic exams. Clinical decision making based on the neurologic exam, the ICP, CT imaging and any other relevant information is the key to improving outcomes. There are several patient scenarios that should prompt consideration of ICP monitoring.[1,3] GCS ≤8 + structural brain injury on head CT GCS >8 + structural brain injury on head CT + high risk for progression (large/ multiple contusions, coagulopathy Severe TBI with a normal CT scan + at least 2 of the following- age >40 years, unilateral or bilateral motor posturing, or SBP <90 mm Hg. Progression of brain injury on repeat CT imaging Patients who require urgent surgery for extracranial injuries Clinical deterioration There is a tiered approach to treating elevated ICP.[1] At each tier, patients should continue to have close neurologic exams as well as interval repeat CT imaging of the head to rule-out the progression of hemorrhage. Tier 1- ensure optimization of analgesia and sedation, elevate head of bed, intermittent drainage of CSF. Tier 2- hyperosmolar therapy- mannitol or hypertonic saline. Consider advanced monitoring, including assessment of cerebral autoregulation and other markers of cerebral oxygenation. If utilizing advanced monitoring, consider hyperventilation to PaCO2 30-35 as long as cerebral oxygenation is maintained. Paralysis with neuromuscular blockade. Tier 3- decompressive craniectomy is a potential salvage therapy- may be associated with decreased mortality, but no improvement in neurologic outcomes.[4,5] Continuous infusion of neuromuscular blockade if there is a response to the test dose in Tier 2. Consider Barbiturate coma. Hypothermia and hyperventilation are no longer routinely recommended. Hyperventilation therapy can be used as a bridge to additional interventions. A study of hypothermia in severe TBI has shown no improvement in early neurologic outcome.[6] References ACS Committee on Trauma. American College of Surgeons Trauma Quality Improvement Program.

Stereotype of a Surgeon Heartless with a God Complex < Back Stereotype of a Surgeon Abrasive, intimidating, self-confident, egotistic, stubborn, arrogant, difficult to work with, aggressive, competitive, and domineering, technically masterful, astute, energetic, and precise.(1) These are just a few of the adjectives that have been used to describe surgeons. The top Google autocompletes for the phrase "why are surgeons…” include arrogant, rough, rude, important, jerks, mean, cold, weird. There is a balancing act between the need to demonstrate confidence while maintaining our humanity and our humility. We wield sharp instruments, and we ask our patients to trust us to fix them while they lay naked and exposed, anesthetized, and vulnerable. So how do we reconcile these seemingly opposing characteristics? How do we show strength, leadership, and confidence in our decision-making and skills and also develop a rapport with patients and families? How do we show our patients that we will be with them to celebrate their recovery and stand by them in the face of complications and setbacks in their recovery? Effective communication is key to relationship building. In general, surgeons are not known for their stereotype that surgeons don't have the best bedside manner. "As a group, surgeons are not well known for their bedside manner."(2) We (usually) operate on completely unresponsive patients, so the stereotype that we don’t like talking to patients is not illogical. This stereotype extends to anesthesiologists. While this is a satirical representation, there is a kernel of truth in the idea that most don’t go into specialties that frequent the OR to spend MORE time talking to patients. "While poor manners aren't commonly accepted in most professional circles, representations of surgeons in popular culture often link technical prowess with rude behavior, and some surgeons have even argued that insensitivity can be helpful in such an emotionally strenuous profession."(2) I probably spend more time talking to patients and their families than the typical surgeon. I find these personal interactions to be truly remarkable. During my training, I developed my style for communication. When I share information with a patient and their family, I treat them as if it were my family member. Based on my perception of their interest in detail and my direct explanation that I will share as much or as little as they like, I tailor my interaction with each new encounter. I believe in full disclosure, including admitting when I don’t have the answers. My training has given me the confidence to admit when I need more information or plan to consult with a colleague. Some might see my willingness to admit imperfections as a sign of weakness. While I didn’t develop my practice regarding disclosure with the express intention of avoiding legal consequences, poor communication and lack of empathy are commonly cited in malpractice suits.(3) So besides the intrinsic benefit of developing respectful interactions with patients, the extrinsic factor of avoiding the courtroom is powerful. A study published in 2019 found that surgeons are regarded as high in warmth and competence, relative to other non-medical occupational groups,(4) in contrast with the stereotype that we lack social skills. The study also noted that female surgeons received higher warmth ratings than male surgeons, while male surgeons received higher competence ratings than female surgeons. It is not an easy task, but building trust with our patients requires us to instill confidence while maintaining our humanity. 1. Logghe HJ. History of Medicine: The Evolving Surgeon Image.

< Back Who Is Our Patient Population? We take care of critically ill and injured patients. Here are just a few examples of the different patient scenarios we manage. We are available 24 hours a day, 7 days a week. Therefore, we often receive consults for various other surgical disease processes outside of what is listed here. Trauma Penetrating wounds from gunshot wounds, stabs, or assaults from any material that breaks the skin and causes bleeding or significant tissue damage Blunt injuries from falls (roof, ladders, etc.), motor vehicle accidents, bicycle accidents, pedestrians struck by vehicles. Non-accidental injuries (abuse, inter-personal violence) Surgical Critical Care Critically ill trauma or emergency general surgery patients. Patients undergoing complex or high-risk surgical procedures or requiring intensive care unit (ICU) admission. Complications from procedural interventions. Intra-abdominal catastrophes. Airway emergencies- patients who are unable to be intubated and require a surgical airway. Emergency General Surgery Appendicitis, Cholecystitis, Diverticulitis. Bowel ischemia or bowel obstruction.

< Back Unusual Case of Peritonitis A 23-year-old male presents to the ED with several days of abdominal pain. He is otherwise healthy and denies any other symptoms. On exam, he has diffuse peritonitis, but no other obvious findings. He is tachycardic with a heart rate in the 110s-120s. His blood pressure is 100s/60s. No significant medical or surgical history. No remarkable events recently. He had plain films of his chest and abdomen. Plain film of the chest and upper abdomen What's going on? Differential diagnosis? Perforated hollow viscus- gastric or duodenal ulcer, bowel obstruction leading to perforation, procedural complication (EGD, ERCP). On further questioning, the patient endorses a recent soccer game during which he blocked a goal and was hit in the stomach. Unsure if it was the soccer ball or a kick to the stomach. He then had a CT of his abdomen and pelvis. CT of the abdomen and pelvis, representative slices What's going on? Diagnosis? Intervention? Free air (pneumoperitoneum) and free fluid are consistent with a perforated hollow viscus. No clear source on the CT. This requires abdominal exploration. We proceeded with exploratory laparotomy. Found liters of succus. There was a single perforation of the small bowel that was resected and anastomosis was performed. The abdomen was closed and a drain was placed. Intraoperative Findings Management of Peritonitis from Perforated Hollow Viscus The hollow viscus refers to the gastrointestinal tract from the esophagus to the rectum. Pain associated with hollow viscus perforation is classically acute onset, constant, severe, and worse with movement. The peritoneal lining of the abdomen becomes inflamed in reaction to the leaking enteric contents. This is a surgical emergency. The diagnosis can be made with the visualization of pneumoperitoneum on an upright chest x-ray (lucency under the diaphragm). A patient with peritonitis and free air requires surgical exploration. A CT scan can help identify the underlying pathology, but is not mandatory and should not delay operative intervention. Non-operative management is reserved for the patient with a sealed perforation (example- retroperitoneal duodenum) or a patient who is a prohibitively high-risk operative candidate (example- patient on palliative or hospice care). Cultural differences Not all cultures have adopted the practice of Western medicine. In some cultures, people still seek advice and medical care from traditional healers. Unfortunately, this can delay treatment if a patient requires operative intervention. Some of the treatments provided by traditional healers can also lead to further injury. This patient with a small bowel injury was seen by a traditional healer several times before he was finally brought to the hospital. The marks on his skin are the result of a practice of cutting the skin to heal the cause of his abdominal pain. Another patient was brought to the hospital for a severe infection of his genitalia. By the time he came to the hospital, his infection was so extensive that he required a debridement of a large portion of the skin in his perineum. He had been seeing a healer who was treating him with a topical solution that had essentially burned his skin, so in addition to the underlying infection, he had severe tissue damage. Previous Next
