Abstract

BACKGROUND AND AIMS:

Keeping in consideration the merits of total intravenous anesthesia (TIVA), a genuine attempt was made to find the ideal drug combinations which can be used in general anesthesia. This study was conducted to evaluate and compare two drug combinations of TIVA using propofol-ketamine and propofol-fentanyl and to study the induction, maintenance and recovery characteristics following anesthesia with these techniques.

SETTINGS AND DESIGN:

A case control study was conducted, which included 100 patients, in the department of Anaesthesiology and Intensive care, Government Medical College and Hospital, Patiala.

PATIENTS AND METHODS:

A hundred patients between the ages of 20 and 50 years of either gender were divided into two groups of 50 each, and they underwent elective surgery of approximately 1 h duration. Group I received propofol-ketamine while group II received propofol-fentanyl for induction and maintenance of anesthesia. All the results were tabulated and analyzed statistically with student's unpaired t-test and chi-square test.

RESULTS:

Propofol-fentanyl combination produced a significantly greater fall in pulse rate (PR; 9.28% versus 0.23%) and in both systolic (7.94% versus 0.12%) and diastolic blood pressures (BP; 8.10% versus 0.35%) as compared to propofol-ketamine during induction of anesthesia. Propofol-ketamine combination produced stable hemodynamics 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. Mean time to protrusion of tongue and lifting of head was shorter in group I.

CONCLUSIONS:

Both propofol-ketamine and propofol-fentanyl combinations produce rapid, pleasant and safe anesthesia with only a few untoward side effects and only minor hemodynamic effects.
