Anaesthetic management of a patient with severe pulmonary hypertension, moderate tricuspid regurgitation and moderate right ventricular dysfunction presenting for a dilation and curettage.

A primigravida woman in her 30s with severe pulmonary hypertension, tricuspid regurgitation and depressed right ventricular function presented for therapeutic termination of pregnancy at 7 weeks gestation after referral and multidisciplinary recommendation. A slowly titrated lumbar epidural was chosen for the primary anaesthetic. Under standard American Society of Anesthesiologists (ASA) monitoring, invasive blood pressure monitoring and continuous transthoracic echocardiography, the patient's right ventricular systolic function was monitored throughout the case using qualitative and quantitative metrics and was notable for a right ventricular systolic pressure of 102.4 mm Hg. Milrinone, started prior to epidural titration, was used for inotropic support. Vasopressin was used in conjunction to sustain systemic vascular resistance while having little effect on the pulmonary vascular resistance. The patient experienced no complications or exacerbation of her pulmonary hypertension and was discharged home the following day.

Urgent Cesarean Section in a Patient on Venovenous Extracorporeal Membrane Oxygenation.

A G7P6 40-year-old female at 20 weeks gestation, with a history of polysubstance use disorder and hepatitis C, presented to the emergency department with severe shortness of breath and hypoxia requiring intubation. After a thorough workup, she was diagnosed with aspiration pneumonitis and was treated with a course of antibiotics. After progressing well, she was soon extubated and transferred to a subacute rehabilitation facility (SAR). There, she acutely decompensated, requiring readmission, reintubation, and venovenous extracorporeal membrane oxygenation (ECMO) cannulation. After a brief period of improvement, the patient became increasingly unstable with hypotension, anemia, and downtrending fibrinogen. Bedside imaging indicated a possible placental abruption. After extensive discussion among the care teams and patient's healthcare proxy, an urgent cesarean section was performed. Although the fetus was determined to be nonviable, the patient tolerated the procedure well and was eventually decannulated from ECMO and transferred to a SAR.

Anesthetic Management of an Obstetric Patient With Ehlers-Danlos and Wolff-Parkinson-White Syndromes.

A 31-year-old, primigravida, nullipara (G1P0) female with a past medical history of Ehlers-Danlos Syndrome (EDS), newly diagnosed Wolff-Parkinson-White Syndrome (WPW), and fetal breech presentation initially presented at 36+5 weeks gestation for an external cephalic version (ECV). The patient noted significant symptomatology related to her WPW which had worsened over the course of her pregnancy despite being started on oral metoprolol. Despite joint recommendations from the anesthesia and obstetric teams to combine the ECV with a same-day scheduled induction of labor or cesarean section, the patient declined. An epidural catheter was placed using ultrasound guidance and slowly titrated with 2% lidocaine; however, the ECV was unsuccessful. At 39 weeks gestation, the patient underwent an uncomplicated low transverse cesarean section under combined spinal-epidural anesthesia. The patient was discharged two days later in stable condition with a referral to an electrophysiologist. Here we describe the anesthetic preparation and management for an external cephalic version and subsequent cesarean section in a patient with these two rare conditions.

Double Lumen Endobronchial Tube Placement for Lung Separation via a Tracheostomy Stoma in a Patient Status-Post Laryngectomy.

A 63-year-old male with a history of chronic obstructive pulmonary disease and squamous cell carcinoma of the larynx status-post laryngectomy and tracheostomy presented for a robotic-assisted right upper lobectomy for neoplasm excision. On physical examination, he was noted to have moderate hypoxia with an SpO2 of 93% on room air. In order to facilitate potential apneic oxygen insufflation and continuous positive airway pressure in the operative lung, a traditional left-sided 35-French double-lumen endobronchial tube was placed through his tracheostomy, and utilized to facilitate lung separation and to improve surgical manipulation. The patient tolerated the procedure well and was extubated to a tracheostomy collar with a 100% fraction of inspired oxygen delivered with 15 liters per minute of flow.

World-Class Innovation, but at What Cost? A Brief Examination of the American Healthcare System.

The American healthcare system, often counted among the world's best, offers expedient access to a highly subspecialized network of physicians who work at the forefront of developing and utilizing novel, cutting-edge procedures, and medications. Patients typically have access to large numbers of qualified physicians in every metropolitan area and thus are afforded the luxury of individual choice in hospital, physician, and experience. Unfortunately, the costs of maintaining such a system are quite profound, and the higher investments do not pay dividends in health outcomes. Here, we elaborate on the greatest achievement and worst flaw in the American healthcare system.

Profound Hyperkalemia and Anemia in a Dialysis Patient With a Gastrointestinal Bleed.

An 80-year-old male receiving dialysis three times per week presented to the emergency room with general malaise after missing four consecutive dialysis appointments. During his workup, he was noted to have a potassium of 9.1 mmol/L, hemoglobin of 4.1 g/dL, and an electrocardiogram showing a first-degree atrioventricular (AV) block, a right bundle branch block, peaked T waves, and a wide QRS complex. During emergent dialysis and resuscitation, the patient suffered respiratory failure and was intubated. The next morning, he underwent an esophagogastroduodenoscopy (EGD), which found a healing duodenal ulcer. He was extubated the same day and was discharged in stable condition a few days later. This case appears to report the highest observed potassium coupled with significant anemia in a patient not affected by cardiac arrest.

Severe hypertrophic cardiomyopathy with left ventricular outflow tract obstruction identified with preprocedural point-of-care ultrasound before emergent tracheal repair.

A woman in her 60s was brought to the operating room directly from the trauma bay for emergent intervention to repair a tracheal rupture sustained during a reported fall from standing height. She was intubated and sedated prior to arrival by paramedics for respiratory distress. Her family reported that the patient had dizziness after standing followed by the patient fainting and striking her neck. During a preprocedural point-of-care cardiac ultrasound examination, we discovered severe left ventricular hypertrophy with a significantly increased ejection fraction and decreased left ventricular cavity size. This prompted emergent cardiology consultation, which confirmed the presence of severe hypertrophic cardiomyopathy with left ventricular outflow tract obstruction. After a brief delay to optimise her heart rate and volume status, the patient successfully underwent an open reduction and internal fixation of the laryngeal cartilage and was discharged in stable condition with plans to undergo a septal myotomy.

Addition of nebulised lidocaine to prevent refractory bronchospasms in a patient receiving serial bronchoscopies.

A patient in his 20s with a history of granulomatosis with polyangiitis required 15 bronchoscopies with dilations in 1 year due to bronchial fibrosis and secretions leading to worsening shortness of breath. During these bronchoscopies, the patient experienced increasingly severe bronchospasms refractory to conventional preventative and treatment methodologies leading to prolonged hypoxia, reintubations and ICU admissions. During his 8th to 15th bronchoscopies, nebulised lidocaine was added to the pretreatment regimen, which eliminated perioperative bronchospasms and allowed for the elimination of all other adjunctive preventative treatments. This case highlights the novel perioperative use of nebulised lidocaine, in combination with nebulised albuterol and intravenous hydrocortisone, to successfully prevent previously refractory bronchospasms in a patient undergoing a general anaesthetic.
