Hemodynamic changes during spinal surgery in the prone position.

Background: Hypertension and fluctuations in blood pressure (BP) during lumbar spinal surgery in the prone position under anesthesia are not unusual. The purpose of this study was to investigate the causes of the decrease in BP during lumbar spinal surgery in the prone position using a noninvasive monitor of cardiac output.

Methods: Twenty ASA Class I or II patients, scheduled for elective lumbar spinal surgery in the prone position, had their hemodynamic status monitored by a BioZ.

Seizure attack during partial hepatectomy in a living donor for liver transplantation under sevoflurane anesthesia.

We report a case of generalized convulsion during partial hepatectomy for the purpose of organ donation for syngenesioplastic liver transplantation under sevoflurane anesthesia. This 23-year-old male Taiwanese living donor had no history of epilepsy. Anesthesia was inducted with fentanyl, propofol and rocuronium was used to facilitate endotracheal intubation.
