Comparison of Two Drug Combinations in Total Intravenous Anaesthesia: Propofol-Ketamine and Propofol-Fentanyl
Keywords:Total Intravenous Anaesthesia, propofol, ketamine, fentanyl
Introduction: TIVA has many advantages over inhalational anaesthesia such as minimal cardiac depression, decreased oxygen consumption, avoids postoperative diffusion hypoxemia, decreases the incidence of postoperative nausea and vomiting etc. This study was conducted to evaluate and compare two TIVA drug combinations using propofol- ketamine and propofol-fentanyl, and to examine the characteristics of induction of anaesthesia, maintenance, and recovery.
Method: 34 patients of ASA grading 1,2 and 3 aged between 20 to 65 years of either sex undergoing short surgical procedures were included in the study. According to Comparison of systolic blood pressure of both the groups at intubation time of anaesthesia in group I and group II. Patients in group I received propofol and ketamine intravenously (IV) to induce anaesthesia. For group II, fentanyl and propofol were administered as IV bolus doses. All the results were tabulated and analyzed statistically.
Result: Propofol-fentanyl combination produced a significantly greater fall in pulse rate and in both systolic and diastolic blood pressures as compared to propofol-ketamine during induction of anaesthesia. Propofol-ketamine combination produced stable hemodynamic during maintenance phase while on the other hand propofol-fentanyl was associated with a slight increase in both PR and BP. During recovery, ventilation score was better in group I while movement and wakefulness score was better in group II.
Conclusions: Both propofol-ketamine and propofol-fentanyl combinations produce rapid, pleasant and safe anaesthesia with only a few untoward side effects and only minor hemodynamic effects.
