A tracheal pouch is a rare complication of successful repair of a congenital tracheoesophageal fistula (TEF). An 18-month-old child with a repaired congenital TEF was scheduled for esophageal dilation to treat his esophageal stricture. Migration of the distal end of the endotracheal tube into a previously undetected tracheal pouch caused an abrupt failure to ventilate at the end of surgery. Given our experience, we recommend to screen the trachea of every patient with corrected TEF for a tracheal pouch when they are scheduled for another procedure requiring general anesthesia.

Clevidipine-induced pulmonary shunting is a little-reported adverse effect, manifesting as refractory hypoxemia, which may cause significant patient harm. We present the case of a mechanically ventilated patient admitted to the intensive care unit following a neurosurgical procedure. ⋯ The hypoxemia recovered within 1 hour of clevidipine discontinuation. Though other calcium channel blockers have been reported to cause pulmonary shunting from vasodilation, this is a novel case report for clevidipine-induced hypoxemia.

Case Reports
Another Role for Angiotensin II?: Vasopressin-Refractory Shock After Pheochromocytoma Resection: A Case Report.
A patient presented with multiple unrelated tumors and was found to have a small but functional adrenal pheochromocytoma. After pheochromocytoma resection, shock developed unresponsive to vasopressin in recommended doses (0.04 U/min infusion plus repeated 1-U boluses) but responded dramatically to an angiotensin II infusion (20 ng/kg/min) with a mean arterial pressure >100 mm Hg. The patient's blood pressure was maintained for 42 hours postoperatively with an infusion rate that ranged from 2 to 38 ng/kg/min. Because vasopressin may not always be effective for postresection shock in people with pheochromocytomas, angiotensin II may prove to be an effective alternative.

Tracheostomy is a weaning technique in patients requiring prolonged ventilation. During this period, complications like tube blockage, fracture of the tracheostomy tube, or cuff rupture can occur. Fracture of the tracheostomy tube can result in the distal end of the tube being dislodged further down the trachea, leading to airway obstruction and hypoxia. We report fracture of a tracheostomy tube in which the distal end was removed, using the inflation line of the pilot balloon to pull out the broken end of the tracheostomy tube.
