ALCANTAR-ESPINOZA, Faustino y GOMEZ-YANES, Edgar Eugenio. Intraoperative intravenous lidocaine pain control: a randomized study. Rev. mex. anestesiol. [online]. 2023, vol.46, n.4, pp.242-245. Epub 26-Feb-2024. ISSN 0484-7903. https://doi.org/10.35366/112293.
Introduction:
having an effective analgesia in the postoperative period is essential to avoid complications associated with pain in patients undergoing laparoscopic cholecystectomy.
Objectives:
test the effectiveness of intravenous lidocaine for postoperative pain in cholecystectomized patients by laparoscopy.
Material and methods:
an experimental, randomized, single-blind study was carried out in patients who underwent laparoscopic cholecystectomy at the No. 1 Regional General Hospital in Obregon, Sonora. They were divided into two groups randomly: group L to whom we applied lidocaine 1.5 mg/k in infusion and group P to whom placebo was applied. A statistical analysis was performed in SPSS v. 22 and a p < 0.05 was considered significant.
Results:
adequate pain management was observed in patients of group L upon admission to PACU (p = 0.002), lower consumption of transoperative fentanyl without statistical difference against placebo (p = 0.086), lower use of post-surgical rescue analgesia (p = 0.045), but higher incidence of adverse effects such as hypotension and bradycardia (p = 0.024).
Conclusions:
the infusion of lidocaine is effective for the management of immediate postsurgical pain; as well it decreases opioid consumption and analgesic rescue dose, with a low incidence of nausea and vomiting, but associated with hypotension after surgery.
