Description détaillée
Obesity is associated with physiological alterations that may increase the risk of postoperative cognitive dysfunction (POCD). The influence of anesthetic techniques on postoperative cognitive outcomes in obese patients remains uncertain.
This prospective randomized study was conducted in obese patients (BMI ≥30 kg/m²) aged 18-65 years undergoing elective laparoscopic abdominal surgery under general anesthesia. Patients were randomly assigned to one of three groups: low-flow sevoflurane anesthesia, normal-flow sevoflurane anesthesia, or total intravenous anesthesia (TIVA). Anesthetic depth was monitored using bispectral index (BIS) monitoring and maintained between 40 and 60 in all groups.
The primary objective was to compare postoperative cognitive function among the three anesthetic techniques using the Mini-Mental State Examination (MMSE). MMSE scores were evaluated preoperatively, at postoperative 30 minutes, and on postoperative day 3.
Secondary objectives included comparison of recovery characteristics, including eye-opening time, extubation time, Modified Aldrete Recovery Scores, and perioperative hemodynamic parameters.
The study was approved by the Marmara University Faculty of Medicine Clinical Research Ethics Committee (Approval No. 09.2022.744) and written informed consent was obtained from all participants before enrollment.

Intervention / Traitement |
|---|---|
|
Expérimental: Low-Flow Sevoflurane
Patients received sevoflurane anesthesia with a fresh gas flow of 1 L/min during maintenance of anesthesia.
Anesthetic depth was maintained with BIS values between 40 and 60.
|
Maintenance of general anesthesia with sevoflurane inhalation.
Patients were assigned to either low-flow (1 L/min) or normal-flow (3 L/min) fresh gas flow anesthesia protocols.
|
|
Expérimental: Normal-Flow Sevoflurane
Patients received sevoflurane anesthesia with a fresh gas flow of 3 L/min during maintenance of anesthesia.
Anesthetic depth was maintained with BIS values between 40 and 60.
|
Maintenance of general anesthesia with sevoflurane inhalation.
Patients were assigned to either low-flow (1 L/min) or normal-flow (3 L/min) fresh gas flow anesthesia protocols.
|
|
Expérimental: Total Intravenous Anesthesia (TIVA)
Patients received total intravenous anesthesia with propofol and remifentanil infusion.
Anesthetic depth was maintained with BIS values between 40 and 60.
|
Maintenance of total intravenous anesthesia using continuous propofol infusion under BIS monitoring.
Continuous remifentanil infusion was administered during maintenance of anesthesia according to study protocol.
