Assessment of postoperative analgesia after intraperitoneal instillation of lornoxicam in laparoscopic appendectomy: a randomized study

Background: The laparoscopic surgeries though results in less postoperative pain it is not a pain-free procedure and early postoperative pain is the most dominant complaint which requires strong analgesia. This study assessed post-operative analgesia after intraperitoneal instillation of lornoxicam in laparoscopic appendicectomy.Methods: This single blind randomized controlled trial was done in a tertiary care Centre of Patna from January 2016 to December 2016. A total of 60 patients scheduled for laparoscopic appenticectomy were randomly assigned into two groups of 30 each (Group A and B) using computer generated random numbers. Patients in group A received intraperitoneal instillation of 8 mg lornoxicam (Diluted in 100 ml of normal saline) and in group B patients received 100 ml of intraperitoneal normal saline. During the post-operative period pain and requirement of analgesia were assessed.Results: The demographic characteristics, clinical presentation and preoperative evaluation for vitals was comparable in group A and B. The mean VAS score was significantly low in group A compared to group B at fourth, sixth, eight and twelfth hour interval (p<0.050). In patients with group B, the requirement of analgesia was high (53.33%) compared to group A (33.33%) (p=0.118).Conclusions: The intraperitoneal instillation of lornoxicam is simple analgesic technique that reduces the pain without adverse effects compared to normal saline.
