Desflurane Anesthesia Used in Patients undergoing Intracranial Operations / 临床麻醉学杂志

ABSTRACT

Objective: To investigate the appropriateness of desflurane anesthesia used in patients undergoing intracranial operations. Methods: Sixteen patients were scheduled for removal of supratentorial mass. A radial artery catheter and a subarachanoid catheter were placed respectively prior to induetion of anesthesia. MAP, cerebrospinal pressure (CSFP), PETCO2 and HR were monitored. Anesthesia was induced with intravenous midazolan, fentanyl, propofol and vecuronium. After endotracheal intubation, anesthesia was maintained by desfurane inhalation in a concentration of 6 % (1MAC) throughout the operation. MAP, CSFP and PETCO2 were recorded before and during induction, at 20min, 30min, 40min and 50min during desflurane inhalation. Results: Compared with the baseline data recorded before anesthesia, CSFP and MAP were decreased significantly during induction. The CSFP tended to increase at 20 min after inhalation of 6 % desflurane, but remained below the baseline till 50min. MAP was decreased following inhalation of 6 % desflurane and kept relatively stable thereafter. No significnt change in HR was noted. Conclusion:Under the condition of PETCO2 28-30mmHg, 1MAC desflurane anesthesia can be used safely without any increase in ICP in patients undergoing intracranial operations.
