Abstract

Induced hypotensive anesthesia is well known anesthetic method. It reduces bleeding into surgical field and provides better visibility for the surgery of cerebral aneurysm. The most current method for induced hypotensive anesthesia is composed of general anesthesia and ganglionic blockade. This study was performed to compare the clinical experience from hypotensive anesthesia with halothane only to hypotensive anesthesia with trimetaphan and halothane. The results of our study were as follows; 1) There are no different technical difficulties during hypotensive anesthesia between halothane induced cases and trimetaphan used cases. 2) No clinical evidence of direct organic damage because of hypotensive anesthesia was found. 3) The prognosis of postoperative recovery may deeply related to preoperative physical state than anesthesia. To conclude through this experience, induced hypotensive anesthesia is a useful method for the cerebral aneurysmal surgery. The technique of deliberate hypotension is not too difficult to use in ordinary equiped hospital.
