Abstract

This report is concerned with our clinical experience of 74 cases of anesthesia using sodium nitroprusside for cerebral aneurysm clipping at the Dong San Medical Center during the last two years. Halothane was used as a main anesthetic agent and blood pressure was easily controlled by the combination of halothane anesthesia and sodium nitroprusside dripping during the clipping period. Arterial cannulations were carried out mainly in femoral arteries to observe continuous MAP throughout the operation time, and CVP catheterizations were performed in an approach of right supraclavicular puncture method to monitor circulating volume. Intermittent blood samples were taken from the arterial cannulations for blood gas analysis to maintain PC02 between 25 to 30mmHg by hyperventilation. Additionally, spinal catheters were inserted into the lumbar subarachnoid space to drain CSF constantly to lower the intracranial pressure. Mannitol and Jasix were injected intravenously at 30 minutes before opening dura mater for osmotic diuresis and tissue dehydration.
