Introduction
The aim of this study was to investigate the effectiveness of lidocaine splash in laparoscopic ovariectomies. Ovarian bursa was splashed with lidocaine 7 mg/kg total dose intraoperatively guided by endoscopy. Pain was evaluated post-operatively with the use of an algometer and the Glasgow Pain Scale.
Clinical cases
Eight healthy, young (7 months to 6 years age) non-pregnant bitches with no underlying conditions were included in this study. Pethidine 3.3 mg/kg IM, acetylpromazine 0.025 mg/kg IM, and meloxicam 0.1 mg/ kg IV were used in all cases as pre-anesthetic medication. Cases were allocated into the lidocaine group (group L, n=4) or the normal saline group (group C, n=4) according to the treatment used, which was administered “blindly”. Pain measurements were performed “blindly” at T0 (max 30’ after extubation), at T1=1h, T2=2h, and T3=4h after the extubation.
Results
Pain assessments revealed lower pain scores (Glascow Pain Scale) and higher pain thresholds (algometer) for animals in group L compared to animals in group C.
Conclusions
The lidocaine splash, as used in the present study, reduced postoperative pain and may be used as a part of multimodal analgesia in laparoscopic ovariectomies in bitches.
