We present a detailed report of an awake craniotomy for recurrent third ventricular colloid cyst in a patient with severe pulmonary arterial hypertension in the setting of Eisenmenger syndrome, performed 6 weeks after we managed the same patient for a more conservative procedure. This patient has a high risk of perioperative mortality and may be particularly susceptible to perioperative hemodynamic changes or fluid shifts. The risks of general anesthesia induction and emergence must be balanced against the risks inherent in an awake craniotomy on a per case basis.

Should Percussion Pacing Have a Role in Perioperative Advanced Cardiac Life Support?: A Case Report.
Percussion pacing involves using one's fist to repeatedly strike a patient's left sternal border in a rhythmic manner. The resulting increase in ventricular pressure can trigger myocardial depolarization and subsequent contraction. We describe the successful treatment of acute preoperative symptomatic sinus bradycardia with percussion pacing in a 63-year-old patient scheduled for placement of a gastric feeding tube after trauma involving spinal cord injury. Although no longer included in current advanced cardiovascular life support guidelines, percussion pacing may be a suitable alternative to chest compressions in multitrauma cases where the force of compressions could cause further complications.

Cuff positions of endotracheal tubes should be confirmed to ensure safe anesthesia. However, determining the cuff positions relative to the cricoid by using chest radiography or fiberoptic bronchoscopy is difficult. ⋯ Thereafter, we adjusted the endotracheal tube depths and confirmed the cuff positions relative to the cricoid. Longitudinal ultrasound images over the larynx and trachea can help confirm the distance from the caudal edge of the cricoid to the saline-inflated cuff.

Point-of-care ultrasound may elucidate reversible causes of cardiac arrest, and its use is supported by international guidelines in the periarrest setting. We present a case in which the treatment of cardiac arrest caused tension pneumothoraces and cardiac tamponade by pneumopericardium. ⋯ Cardiac imaging was false negative for tamponade, because the latter was caused by air and not fluid. Diagnoses are not to be excluded with inconclusive point-of-care ultrasound examinations, which should prompt further clinical evaluation and imaging.

We report a gravida in fulminant acute respiratory distress syndrome, mechanically ventilated at 27 weeks estimated gestational age, who further deteriorated into severe combined hypercarbic, hypoxemic respiratory failure. At 30 weeks estimated gestational age, she was placed on venovenous extracorporeal membrane oxygenation (ECMO) because of refractory respiratory failure. Her physical status improved without fetal deterioration. ⋯ Six days later, complications of ECMO (pulmonary hemorrhage) led to emergent abdominal delivery of a living male child. She was successfully weaned from ECMO 8 days later. The implications of ECMO during pregnancy are discussed.
