Efficacy of low-dose epidural anaesthesia in surgery of the anal canal--a randomised controlled trial.
The aim of the study was to compare in terms of patient comfort, surgical requirements and anaesthetic safety, the difference between epidural and general anaesthesia in patients undergoing surgery of the anal canal. The study was undertaken on 50 adult patients undergoing anal surgery. By random allocation 25 were given a general anaesthetic while 25 were given a low-dose epidural using 0.375% bupivacaine. Advantages and disadvantages of both methods were noted in the study. It was concluded that low-dose epidural is a more effective means of providing analgesia, while maintaining adequate sphincter tone for surgery on the anal canal, than general anaesthesia.
