POCD in Elderly Patients Following Desflurane or Sevoflurane General Anesthesia

Completed

• Conditions: 1. Postoperative Cognitive Dysfunction

• Registration Number: NCT01199913
• Lead Sponsor: Loma Linda University

Brief Summary

The use of desflurane in elderly subjects (\>65 years old) undergoing general anesthesia with endotracheal intubation will result in decreased POCD compared to sevoflurane if the patient's MAP is within 20% of the patient's baseline and the cerebral suppression state index stays within the moderately anesthetized range during general anesthesia.

Primary Outcome Measures

Name	Time	Method
POCD in Elderly Patients Following Desflurane or Sevoflurane General Anesthesia	Both groups will complete the MMSE at 1, 6, and 24 hours after the end of anesthesia or to disharge up to 7 days.	The primary outcome measure will be changes in cognitive function after anesthesia as measured by MMSE.

Secondary Outcome Measures

Name	Time	Method
Secondary outcome measures will include: 1) time to extubation, anesthetic complications (e.g. coughing during extubation), 2) time to readiness for discharge from PACU, 3) length of hospital stay, and 4) any postoperative complications.	24 hours to 7 days
