A COMPARATIVE STUDY OF CAUDAL BLOCK USINGLIGNOCAINE ALONE AND WITH KETAMINE FOR ADULTANORECTAL SURGERIES

Background -we want to compare the effects of lignocaine alone & lignocaine with ketamine in the caudal block for anorectal surgeries Methods- A prospective, randomized, comparative study was conducted at the Department of Anaesthesiology, ACSR Govt Medical college on 50 ASA I, and II patients aged between 18 to 60years posted for elective anorectal surgeries, during the period of November 2020 to February 2022,by dividing the patients into two groups Results-In this study the mean time to the first analgesia was 7.9 min. in the control group and 5.6 in the study group (p < 0.05). The mean time to start was 13 min. in the control and 11 min. in the study group (p < 0.05). The sensory block level reached in the control group was T12 and in the study group was T 10. The motor blockade was significantly less in the study group than in the control group (p < 0.05). Anal sphincter relaxation was better in the study group than in the control group. The discomfort caused by the awkward positioning was less in the ketamine group than in the control. In the study group, patients had acceptable sedation which contributed to a sense of well-being superior patient satisfaction and better working conditions for surgery. Both groups were compared in the incidence of intraoperative and postoperative complications. In the study group the total duration of analgesia was significantly prolonged (210 min. vs. 247 min. p value
