Abstract:

Objective   To evaluate the effect of propofol in cataract surgery anesthesia for mental illness. Methods   We investigate 15 psychiatric patients who underwent cataract surgery from June 2006 to July 2012. In operating room, oxygen inhalation was given through nasal catheter and intravenous access was established. ECG, HR, BP, SpO2, PetCO2 and BIS were continuously monitored. 1-2mg/kg propofol was injected and the BIS value was kept below 60 before operation. Anesthesia was maintained by 2-5mg/(kg·h) propofol microinjection, and additional 20-50μg fentanyl was given in case of body movement in response to pain. BIS value was maintained at 40 to 60 during the operation, and propfol pumping was stopped at the end of surgery. Results   All operations were successfully performed. Only two cases had transient respiratory depression, but their SpO2 was normal. The situation was improved after reducing the speed of propofol pumping, and no special treatment was given. No anesthesia-related complications happened in remaining cases. No anesthetic sequelae or psychotic exacerbations were found during postoperative follow-up. Conclusion   Propofol can be used in psychiatric patients’ anesthesia for cataract surgery. At the same time, preoperative visit, intraoperative monitoring, and postoperative management and nursing should be enhanced in order to ensure safety of psychosis patients during perioperative period.
