Efficacy of Caudal Block on Intra-operative Anal Sphincter Muscle Tone and Post-operative Analgesia During Anal Sphincter Sparing Procedures Under General Anaesthesia

upplementing general anaesthesia with caudal analgesia in sphincter sparing procedures might be useful as it will provide a satisfactory combination of sphincter muscle tone preservation, good intraoperative and postoperative analgesia along with a reduction in the consumption of opioids and anaesthetic drugs. To the best of our knowledge, this anaesthetic technique was not tested in sphincter sparing procedures before.
