Summary

The aim in this study was to quantify the difference in cisatracurium and sufentanil consumption, and its recovery period, when patients are under balanced general anesthesia with 1% sevoflurane and patients under only sevoflurane general anesthesia, using a closed loop computer control infusion. Investigators further investigated this effect on its recovery period and sufentanyl consumption.

Detailed description

156 patients of American Society of Anesthesiologists (ASA) physical status I and II were assigned to three groups. The patients were all on schedule for elective general surgery under general anesthesia with duration of at two to four hours. All patients were induced with Etomidate (0.2mg/kg), Midazolam (0.05-0.1mg/kg), Sufentanil (0.3-0.5µg/kg) and a bolus dose of Cisatracurium (0.15mg/kg). Patients were aged between 20 and 65. The maintenance of anesthesia in each group varies as follows: Patients in Group 1 were all maintained with Total Intravenous Anesthesia, Group 2 with Sevoflurane at 1% and propofol infusion, Group 3 with only sevoflurane. Muscle paralysis is maintained using a closed-loop computer gated infusion of Cisatracurium which kept T1 \<1% by giving increasing the infusion rate intra-operatively when required. Analgesia was maintained by intermittent bolus dose of 10-20 µg of Sufentanil.

Conditions

• Drug Interaction Potentiation

Interventions

Type	Name	Description
DRUG	1% Sevoflurane	In this group of patients, the maintenance of anesthesia is done by 1% sevoflurane + propofol infusion. Propofol infusion is adjusted according to the Bispectral Index.
DRUG	Propofol	In this group the maintenance of anesthesia is maintained by only propofol infusion.
DRUG	Sevoflurane	In this group only sevoflurane was used for maintenance of anesthesia. the dose of sevoflurane is adjusted to maintain Bispectral Index within 45 and 55.
