Sevoflurane vs. Isoflurane for Low-Flow General Anaesthesia for Abdominal Surgery - Full Text View

Sponsored by:	General Hospital Dubrovnik
Information provided by:	General Hospital Dubrovnik
ClinicalTrials.gov Identifier:	NCT00521612

Purpose

Two groups of patients are going to have abdominal surgery with low-flow general anaesthesia. Group A (sevoflurane group, experimental group) will use volatile anaesthetic sevoflurane. Group B (isoflurane group, control group) will use volatile anaesthetic isoflurane. It will be observed differences between volatile anaesthetic sevoflurane and volatile anaesthetic isoflurane for providing low-flow general anaesthesia for abdominal surgery. Duration of this randomised controled trial will be approximately 2 months. Estimated sample size will be 82 persons (41 in sevoflurane group and 41 in isoflurane group).

Primary Outcome Measures:

Differences between volatile anaesthetic sevoflurane and volatile anaesthetic isoflurane for providing low-flow general anaesthesia for abdominal surgery. [ Time Frame: approximately time for this trial is about 2 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Differences in awakening patients from low-flow general anaesthesia provided by sevoflurane and isoflurane. [ Time Frame: approximately time for this trial is about 2 months ] [ Designated as safety issue: Yes ]

Arms	Assigned Interventions
A: Experimental Sevoflurane group, experimental group	Drug: sevoflurane Volatile anaesthetic sevoflurane 1 MAC (2,0 vol%) will be administer to the patients in the form of gas (via respiration). First 20 minutes of anaesthesia will be period of saturation of the body with anaesthetic sevoflurane. After 20 minutes the depth of anaesthesia will be titrated with level of anaesthetic sevoflurane. Change will be +10 % of sevoflurane MAC (0,2 vol%) for every change of signs that indicate shallow anaesthesia. Change will be -10 % of sevoflurane MAC (0,2 vol%) for every change of signs that indicate too deep anaesthesia. Measuring points will be every 5 minutes during surgery.
B: Active Comparator Isoflurane group, control group	Drug: isoflurane Volatile anaesthetic isoflurane 1 MAC (1,2 vol%) will be administer to the patients in the form of gas (via respiration). First 20 minutes of anaesthesia will be period of saturation of the body with anaesthetic isoflurane. After 20 minutes the depth of anaesthesia will be titrated with level of anaesthetic isoflurane. Change will be +10 % of isoflurane MAC (0,12 vol%) for every change of signs that indicate shallow anaesthesia. Change will be -10 % of isoflurane MAC (0,12 vol%) for every change of signs that indicate too deep anaesthesia. Measuring points will be every 5 minutes during surgery.
