< Back GERD What is GERD? Gastroesophageal Reflux Disease (GERD), more commonly known as heartburn, is caused by acid from the stomach moving into the esophagus, which causes a burning pain in the middle of the chest. Anatomy After swallowing, food moves down the esophagus and into the stomach. The lower esophageal sphincter (LES), which is at the connection between the esophagus and stomach, prevents stomach contents from moving back into the esophagus. The lower esophageal sphincter is located below the diaphragm, where pressure from the abdominal organs helps keep the sphincter closed. There are different causes of GERD, but the lower esophageal sphincter is key to preventing reflux. See below for more details about why GERD occurs. Source: UpToDate Images: Gastroesophageal Reflux (GERD) Causes of GERD Decreased pressure of the lower esophageal sphincter- if the lower esophageal sphincter is too loose/ relaxed, stomach contents move more easily into the esophagus. This can be a pre-existing condition but it can also be caused or worsened by lifestyle habits. For example, tobacco and certain foods such as alcohol, chocolate, caffeine, carbonation, mint, citrus/ tomato-based foods, spicy/ fried/ fatty foods, can also decrease the pressure of the sphincter. Eating too much/ too fast→ overfilling the stomach leads to increased pressure, causing stomach contents to be pushed into the esophagus Laying flat- when you are standing or sitting upright gravity helps avoid reflux by keeping food in the stomach, but when laying flat, stomach contents can move into the esophagus more easily. This is why symptoms are often more severe at night or first thing in the morning. Hiatal hernia - when the lower esophageal sphincter is able to move into the chest, it no longer has the external pressure normally present when it’s in it’s correct position, and it more easily allows stomach contents to move into the esophagus. See link for image. Obesity or pregnancy- increased pressure on the abdomen from excess weight can put pressure on the stomach and allows stomach contents to move into the esophagus for easily. GERD: Symptoms and Causes [Mayo Clinic: Patient Care & Health Information] Diagnosis Symptoms are often adequate to diagnosis GERD. A swallow study can provide further information. This study is performed in radiology, and involves drinking contrast material and having x-ray images taken to evaluate the esophagus and stomach while you swallow. This study can diagnose esophageal problems, such as poor muscle function leading to swallowing difficulty. In addition, a hiatal hernia can be identified. John Hopkins Medicine: Barium Swallow An esophagogastroduodenoscopy (EGD), also known as an upper endoscopy (see link) can be used to assess the inner lining of the esophagus, stomach and the first part of the small intestine (duodenum). There are many things that can be identified on an EGD, but specifically related to GERD, damage to the lining of the esophagus and the presence of a hiatal hernia can be identified with an EGD. Patient education: Upper endoscopy (Beyond the Basics) [UpToDate] Upper Endoscopy [Society of American Gastrointestinal and Endoscopic Surgeons (SAGES)] Additional testing can be performed based on symptoms, results of initial testing and response to treatment. Esophageal manometry- a study to evaluate the muscle function of the esophagus ( pH test- a study to evaluate how much acid the esophagus is exposed to, which is one measure of the severity of GERD. GERD: Diagnosis and Treatment [Mayo Clinic: Patient Care & Health Information] Treatment Lifestyle Modifications [ Patient Handout: Anti-Reflux Diet and Lifestyle Modifications ] Eat slowly, avoid eating large meals and stop eating before you feel full. Avoiding alcohol, chocolate, caffeine, carbonation, mint, citrus/ tomato-based foods, spicy/ fried/ fatty foods. Avoid lying down for at least 2-3 hours after meals. Don't snack after dinner/ before bed. Elevating the head of the bed by 6-8 inches. This is NOT done by placing multiple pillows under your head- multiple pillows would actually increase pressure in the abdomen (like doing a sit-up or crunch). For more information, see this guide from the Kingsley clinic. Lose weight. Stop smoking. Avoid tight-fitting clothing. Medication Over the counter antacids Prescription medication Surgery Depending on how well medication and lifestyle modifications improve your GERD symptoms, and depending on the results of your other studies, such as your swallow study, esophageal manometry and pH testing, surgery may be an option for GERD.

< Back Mangled Extremity- Keep or Cut? A 42-year-old male was struck by a vehicle as he was crossing the street. He was brought in by EMS. He had a depressed GCS and unequal pupils, and he was intubated for concern for airway compromise. He had a significant injury to the right lower extremity with diffuse bleeding, but no active arterial bleeding. Compressive dressings were applied. He had fluid in the LUQ window of his FAST. He was hemodynamically unstable. Initial evaluation and management? Imaging? Poly-trauma patients demand prioritization and quick decision making, and the simple step-wise algorithms designed for each injury in isolation are less helpful. Patients with blunt abdominal trauma and hemodynamic instability require emergent operative intervention. Patients with a depressed GCS and an abnormal pupil exam require emergent CT imaging to define the severity of their head injury and consultation with neurosurgery. Patients with a mangled extremity require a CT scan to define the vascular injury. In the setting of blunt abdominal trauma, a positive FAST and hemodynamic instability, he was transported to the OR emergently. If there was an option for a rapid CT en route to define his TBI, that would have been ideal. But hypotension is associated with worse outcomes for TBI patients, so the priority is stopping the bleeding. We performed a midline laparotomy, splenectomy, and repaired a diaphragm injury. We placed a temporary abdominal closure. Intraoperative Image What do we do about his mangled lower extremity? Consult vascular or ortho? Ex-fix? Amputate? There are several important tasks. Assessment of injury to neuromuscular structures is vital. If possible, rapid restoration of arterial blood flow is beneficial. However, it is vital to evaluate the need for amputation. This decision requires consideration of current physiologic status, co-morbidities, and baseline functional status. It's sometimes a question of life versus limb. Orthopedic and vascular specialists can be consulted, but it is important not to lose sight of the patient's overall clinical status. A brief temporizing procedure to restore blood flow with a shunt, stabilize bony structures, and preserve any remaining soft tissue may be appropriate, but a lengthy vascular repair and bony fixation are likely not ideal. The patient's baseline functional status, social support, and co-morbidities were unknown. Based on the severity of his extremity injury, high injury burden, and need for urgent head CT, my recommendation was for immediate amputation. This decision requires weighing the risks/ benefits of limb salvage (prolonged time in the operating room for stabilization, risk of ongoing tissue ischemia leading to systemic complications) vs amputation (limb loss). Our orthopedic specialists felt they could salvage his limb, and give him a chance to be an active participant in the decision-making. We agreed to a time limit to minimize operative time, so the limb was stabilized temporarily with a plan for ongoing evaluation of the limb viability. Managment of the Mangled Extremity WTA Algorithm Management of patients with mangled extremities remains controversial. Severe scoring systems have been created, with variable success in predicting who requires amputation. In the acute setting, the trauma surgeon must weigh the risks and benefits of limb salvage versus immediate amputation. If the limb injury is devastating (perhaps only hanging on by a small skin bridge), and the patient has other injuries that require immediate intervention, rapid amputation can be life-saving. If the decision to amputate is less clear, a second opinion from a colleague and orthopedics should be elicited. There have been remarkable advances in the ability to restore function to mangled extremities, and discussion with specialties can be very helpful. "Therapeutic advances in the treatment of vascular, orthopedic, neurologic, and soft tissue injuries have reduced the diagnostic accuracy of the MESS in predicting the need for amputation. There remains a significant need to examine additional predictors of amputation following severe extremity injury." Loja, Melissa N et al. “The mangled extremity score and amputation: Time for a revision.” J Trauma Acute Care Surg. 2017;82(3):518-523 The trauma surgeon must maintain perspective on the whole patient- spending hours doing meticulous vascular or nerve dissection/ repair or extensive orthopedic manipulation can be an intolerable burden on a patient with multiple other injuries. 1. Control active hemorrhage. 2. Restore anatomic limb alignment. 3. Assess distal arterial flow→ evidence of vascular injury→ CTA to characterize injury. 4. Assess neurologic function. Unable to control active hemorrhage or there is hemodynamic instability→ proceed to OR. Assess for the need for immediate amputation. Factors to consider: Complex, segmental, severely comminuted fracture. Large circumferential soft tissue loss or massive soft tissue necrosis. Compartment syndrome with myonecrosis. Nerve disruption. Massive contamination. Prolonged warm ischemia >6 hours. Poor distal anastomosis options. No immediate amputation→ intraluminal shunt to re-establish perfusion. Then assess bony and nerve injury. Evaluate risks/ benefits of limb-preservation. Previous Next

< Back Before Surgery American College of Surgeons (ACS) Operation Brochures for Patients Patient Education: Preparing for Your Surgery How Can I Be Strong for Surgery? Strong for Surgery is a program that works with surgeons and hospitals to provide tools like checklists that surgeons can use to assess your risks in four target areas: nutrition, blood sugar control, smoking cessation, and medications. You can lower your risk by being better prepared for your operation. NSQIP Surgical Risk Calculator Disclaimer: The ACS NSQIP Surgical Risk Calculator estimates the chance of an unfavorable outcome (such as a complication or death) after surgery. The risk is estimated based upon information the patient gives to the healthcare provider about prior health history. The estimates are calculated using data from a large number of patients who had a surgical procedure similar to the one the patient may have. Previous Next

< Back Vent Mgmt #5: Weaning When is the patient ready to start ventilator weaning? Resolution of pathology resulting in the need for mechanical ventilation Able to assess mental status (ie can the patient follow commands) Hemodynamics and respiratory physiology is optimized (ie ABG normalized or returned to patients baseline, and normalization or stabilization of cardiac function) Minimal ventilator settings (FiO2 21%, PEEP 5) NOTE: Even if there is no immediate plan to extubate, sedation holiday and spontaneous breathing trials should still be performed [unless there are specific contraindications] Spontaneous breathing trial Spontaneous mode of ventilation (such as pressure support or CPAP) with 5-8 cm H2O support during inspiration (basically overcoming the force required to breath through the small diameter of the ETT) Failing SBT Hemodynamic instability (hypotension or hypertension, tachycardia or bradycardia) Agitation Respiratory instability (hypoxia, inadequate tidal volume, tachypnea or decreased respiratory rate) Extubation parameters- how do we know if the patient is ready to be liberated from the ventilator? Able to generate adequate minute ventilation Rapid shallow breathing index (RSBI)- RR/ TV. High respiratory rate (rapid) and low tidal volume (shallow) are more suggestive that a patient isn't appropriate for extubation. Value <105 suggests the patient will successfully extubate. This is also known as the Tobin index.[1] Negative inspiratory force (NIF)- the patient's ability to generate negative pressure with inhalation. Cuff leak- ability to move air around the endotracheal tube. Not mandatory to evaluate for cuff leak prior to extubate EXCEPT for patients is at high risk for airway edema (traumatic intubation, intubated >6 days, large ETT, female, reintubation after unplanned extubation). Reasons for failed ventilator weaning Prolonged hospitalization and associated weakness Hypophosphatemia Primary process requiring mechanical ventilation is unresolved Passed SBT...but failed ventilator liberation? Excess secretions/ inability to cough Cardiac instability related to physiological changes with loss of positive pressure (specifically decrease in intra-thoracic pressure leading to decreased cardiac output) Tobin Index.
