Effect of intravenous lignocaine on perioperative stress response and post-surgical ileus in elective open abdominal surgeries: a double-blind randomized controlled trial.


PMID 25078385

Abstract

Perioperative stress response can be detrimental if excessive and prolonged. Intravenous (i.v.) lignocaine, while being an effective analgesic, has the added benefit of anti-inflammatory activity. This study was done to assess the effect of i.v. lignocaine on operative stress response and post-surgical ileus after elective open abdominal surgeries. Patients (n = 134) were randomized into two groups (n = 67 each) to receive an i.v. infusion of lignocaine (group L) or saline (group S) as a bolus of 1.5 mg/kg at intubation followed by an infusion of 1.5 mg/kg/h throughout the surgery until 1 h post-surgery. Total leukocyte count (TLC), C-reactive protein (CRP) and interleukin-6 (IL-6) levels immediately and 24 h after surgery were compared with preoperative levels. Time to first passage of flatus and stools post-operatively was noted. Post-operative pain scores, analgesic requirements, and incidence of post-operative nausea and vomiting (PONV) were assessed in the two groups. Post-operative surge in TLC, CRP and IL-6 was attenuated in group L as compared to group S (P < 0.001, 0.018, <0.001). Time to passage of flatus and stools was earlier in group L (P = 0.04, 0.02). PONV was lesser in group L at 6 and 18 h post-surgery (<0.001, 0.28). Post-operative pain scores and post-operative morphine requirement were significantly less in group L at each point of time post-operatively (P < 0.001, <0.001). Perioperative i.v. lignocaine infusion attenuates the operative stress response, provides effective analgesia and reduces the need for opioids post-operatively. Through these effects, it reduces post-operative ileus and the incidence of PONV.
