  • Kelly Snap Mosquito | Doc on the Run

    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.

  • Tutorial: Vent Mgmt #2: Modes | Doc on the Run

    < 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

  • Vignette: Intracranial Hypertension | Doc on the Run

    < 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.

  • Heartless with a God Complex | Doc on the Run

    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.

  • Vignette: Shot in the Chest- Aortic Occlusion | Doc on the Run

    < 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.

  • Vignette: Machete Attack- Neck Trauma | Doc on the Run

    < Back Machete Attack- Neck Trauma A 42-year-old male was brought from an outside hospital after sustaining deep, extensive penetrating wounds to the neck and forearms. When he arrived at the hospital, we noted defensive wounds on his forearms and a deep laceration across the anterior neck. The report from EMS was that the patient was assaulted with a machete. What are the management priorities? Prioritize primary and secondary survey and treat life-threatening injuries first. Don't be distracted with impressive wounds. Secure the airway and control active hemorrhage. He was initially seen at a small community hospital, where an endotracheal tube was placed through the tracheal wound, and then he was transferred to our facility. He was rapidly transported to the operating room for evaluation. What structures need to be evaluated? Vascular structures (carotid arteries, vertebral arteries, jugular veins) and upper airway/ digestive structures (esophagus, pharynx). The head and neck team was consulted, and they evaluated him in the operating room. The wound's extent was explored thoroughly. Surprisingly, there were no injuries to the vascular structures, and the injury was isolated to the airway. The endotracheal tube was exchanged for a formal tracheostomy and a stent was placed in the upper airway to prevent luminal narrowing while the repair healed. The wound was closed in layers. Management of Penetrating Neck Trauma WTA Algorithm Anatomy Zone 1 Clavicles/ sternum to cricoid Zone 2 Cricoid to angle of mandible Zone 3 Angle of the mandible to the skull base Hard signs- airway compromise, massive subcutaneous emphysema/air bubbling through the wound, expanding or pulsatile hematoma/ active bleeding, shock, neurologic deficit, hematemesis. Soft signs- hemoptysis, blood in the oropharynx, dyspnea, dysphagia, dysphonia, subcutaneous air, chest tube air leak, non-expanding hematoma, bruit/ thrill. Hard signs or hemodynamic instability→ ensure airway and transport to OR. No immediate operative indications? Depends on symptoms and the zone of injury. Zone 1 and 3- CTA to rule out vascular and aerodigestive injuries; assess the trajectory of injury. Injury→ repair. Concerning trajectory→ triple endoscopy (laryngoscopy, bronchoscopy, and esophagoscopy). Zone 2- symptomatic→ OR. Asymptomatic- serial exams or imaging. Operative approach The most common incision for exploration of neck wounds is along the anterior border of the sternocleidomastoid (SCM) muscle. Exposure of Zone 1 and 3 are more challenging and endovascular adjuncts are useful. Zone 1 may require median sternotomy with extension along the SCM. Zone 3 requires mobilization of the mandible. Zone 2 can be approached with a transverse cervical collar incision with SCM extension. - Tracheal injuries are repaired with monofilament absorbable suture. - Esophageal injury- debride unhealthy edges, ensure full exposure of mucosal defect, repair defect (single or double layer), buttress with SCM, or strap muscle. Place drain. - Combined tracheoesophageal injury- repair, and ensure repairs are isolated with interposition of a well-vascularized muscle flap. Previous Next
