Mannitol Improves Cerebral Oxygen Saturation

Status Completed

Clinical Trial Summary

Decreased cerebral oxygen saturation (rSO2) was reported to occur during insufflation for laparoscopic procedures due to increased Intracranial pressure (ICP) with resultant decrease in cerebral perfusion pressure.

Clinical Trial Description

Forty patients scheduled for laparoscopic cholecystectomy will be enrolled in this double blind, randomized controlled study. Patients will receive either 0.5g/kg of 20% intravenous (i.v.) mannitol infusion over 10 minutes immediately before induction of anesthesia (group M) or an equal volume of 0.9% normal saline instead (group C). Primary outcome measure is rSO2. Secondary outcome variables include extubation time, clinical assessment of consciousness recovery using the modified Observer's assessment of alertness/sedation scale (OAA/S) and the mini-mental state examination (MMSE) for cognitive evaluation after recovery. ;

Study Design

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
