Abstract
INTRODUCTION:Pain is one of the most important reasons for the patients concern after surgery. The perfect sedative should have properties like rapid onset, least pain and adverse effects. AIM: To assess the effect of sevoflurane plus propofol on postoperative pain, haemodynamic stability and complicationafter lumbar disc surgery. MATERIALS AND METHODS: This was a randomized double- blind clinical trial. A total of 75 patients scheduled for elective lumbar disc surgery with simple random sampling design receivedsevoflurane (n=25, induced with Thiopentone and maintained with sevoflurane), propofol (n=25, induced and maintained with propofol) and sevoflurane plus propofol (n=25, induced with propofol and maintained with sevoflurane). Visual Analog Scale (VAS) was used to determine the intensity of postoperative pain. Complications after surgery and haemodynamic changes during surgery were recorded. RESULTS: The mean pain intensity and morphine consumption in the sevoflurane plus propofol group was lower compared to the propofol and sevoflurane groups at different intervals (p<0.001). The prevalence of shivering, nausea and vomiting in the sevoflurane plus propofol group was 24%, 28%, 28% respectively vs sevoflurane group 32%, 60%, 48% respectively and propofol group 32%, 16%, 12% respectively with p-value > 0.05, <0.001, <0.05 respectively. The mean blood pressure and heart rate were significantly lower in the sevoflurane plus propofol group compared to the propofol and sevoflurane groups (p<0.001). CONCLUSION: According to the effect on pain and complicationsafter lumbar disc surgerysevoflurane plus propofol can be regarded as safe and alternative drug in general anaesthesia for these patients.
