[Hyperlactemia during undiagnosed pheochromocytoma resection under laparoscopy].

A 51-year-old man was scheduled to undergo adrenal tumor resection. Because his general physical findings and labolatory tests were not particular, and his serum concentrations of noradrenaline and adrenaline were within normal limit, the tumor was diagnosed as nonfunctional adrenal tumor. Anesthesia was induced with propofol, fentanyl and maintained with oxygen, air, propofol and remifentanil.

[Anesthetic management for laparoscopic resection of adrenal pheochromocytoma in a woman with chronic renal failure].

A 52-year-old woman, undergoing hemodialysis for chronic renal failure over thirty years, developed pheochromocytoma. Her serum concentrations of noradrenaline (NA) and adrenaline were 5,330 pg x ml(-1) and 212 pg x ml(-1), respectively. She had often developed hypertensive crisis and also hypotensive crisis during hemodialysis, and quite often she had to give up continuing hemodialysis before its end.

An unusual case of airway obstruction at the tip of an endotracheal tube caused by insertion of a nasogastric tube.

We report an unusual case of ventilatory impediment caused by the obstruction of an endotracheal tube (ETT) by a nasogastric (NG) tube. A 72-year-old woman with bronchial asthma was scheduled for colostomy closure. An ETT of 7.
