The Effect of Sugammadex on Time of Sciatic Block by Perineural Bupivacaine in Rats

| Summary: | Objectives We aimed to investigate the effect of sugammadex on the motor, sensory and deep sensory block in the sciatic nerve created by bupivacaine in rats. Materials and Methods 18 Sprague-Dawley adult male rats treated with unilateral sciatic nerve block by bupivacaine (0.2 ml) were randomly divided into three groups. Control group (Group C, n = 6, 1.5 mL saline) perineural sugammadex group (Group PNS, n = 6, 16 mg/kg) and intraperitoneal sugammadex group (Group IPS, n = 6, 16 mg/kg) Motor, sensory, and deep sensory functions were evaluated every 10 minutes by a blind researcher. 6 tissue samples each belonging to the sciatic nerve, 1.5 cm in length and 0.2 cm in diameter, were taken from paraffin blocks. Sections of 3-4 micrometers were stained with Hematoxylin + Eosin, Masson Trichrome dyes and examined under a light microscope. Results There was no statistically significant difference between 3 groups in terms of the time to return to normal motor, sensory and deep sensory function. There was also no significant difference in edema, extracellular matrix, and myelin. Inflammatory cells were seen in all groups, mainly epineurium, epineurium, and perineurium. Conclusion There are findings of no histological effects or effects on local block of sugammadex in rats undergoing sciatic nerve block. |
