Music and its effect on sedative requirements in patients undergoing procedures under regional anaesthesia

ABSTRACT

The study was carried out to detect the effect of music and elimination of operating room noises on the dose requirement of propofol as sedative in awake patients undergoing urological procedures under regional anaesthesia. Case-Control study. This study was carried out at Departments of Anesthesiology and Surgery, G.G.S. Medical College and Hospital, Faridkot, India. 75 patients who were to undergo different procedures under spinal anaesthesia were randomly divided into three groups Group I [control group] patients exposed to normal operating room noises; Group II patients with occlusive head phones but no music and Group III patients with occlusive head phones and music of their choice Ramsay sedation score was used to assess the level of sedation, which was maintained at the level of 3 and monitored every 5 minutes. The head phones were removed temporarily to assess the sedation level. The Sedation was achieved with inj. propofol, and total close usedwas noted. As compared to group I [control group], patients of group II and group III showed statistically significant [p < 0.05] reduction in propofol requirement as compared to Group-I [24.52 +4.12 vs 19.80 +4.04 and 18.56 +3.56] to attain the sedation score of 3 on Ramsay Sedation Score. Patients of these groups showed no statistically significant difference in propofol requirement when compared with each other. Group II patients did not hear any music but required statistically significant [p < 0.05] less propofol as sedative as compared to group I. The elimination of ambient and disturbing operating room noises is sufficient enough to reduce the sedative requirement of propofol in anxious awake patients under spinal anaesthesia. Music, as a non pharmacologic adjunct to relieve anxiety may further reduce this requirement
