| Background Surgical stress response is a host defense mechanism against tissue injury but its exaggeration can cause postoperative morbidity. Anaesthetics can modulate this response with variable degrees. Therefore, this study was conducted to compare the immune-modulatory effects of intraoperative intravenous infusion of propofol versus ketamine. Patients and Methods Forty patients scheduled for open colectomy under inhalational based general anaesthesia were included. They were allocated randomly into Group P (n=20) which was given intravenous propofol 1% at a subanaesthetic infusion dose of 17μg/kg/min, and group K (n=20) which was given Ketamine 0.3% (150mg/50ml) at a subanaesthetic infusion dose of 5μg/kg/min. The primary outcome was the post-infusion serum IL-6 2 hours after the start of infusion. The secondary outcomes were IL-1β, TLC, absolute neutrophil count and N/L ratio, glucose level, CRP level, postoperative agitation, mean NRS score for pain at rest and movement during the first day, and time to the resumption of GIT function. Results Post-infusion serum IL-6 after 2 hours was significantly higher in group K (P<0.001). Additionally, Serum IL-1β, glucose and CRP levels were significantly higher in Group K. Postoperative agitation score was significantly higher (P<0.001) and mean postoperative pain score during rest was significantly lower (P 0.003) in group K. Other outcomes were comparable between both groups. Conclusions Propofol is more effective than ketamine in reducing the surgical stress response as noted by decreased IL-6 and IL-1β, blood glucose, and CRP when compared with ketamine. | ||||
