Key result
Low-dose epidural anaesthesia was a more effective means of providing analgesia and maintaining adequate sphincter tone for anal surgery than general anaesthesia.
Why the study?
Does low-dose epidural anaesthesia using 0.375% bupivacaine improve patient comfort, surgical requirements, and anaesthetic safety compared to general anaesthesia in adult patients undergoing surgery of the anal canal?

Does low-dose epidural anaesthesia using 0.375% bupivacaine improve patient comfort, surgical requirements, and anaesthetic safety compared to general anaesthesia in adult patients undergoing surgery of the anal canal?
Low-dose epidural anaesthesia with 0.375% bupivacaine provides superior analgesia and maintains adequate sphincter tone compared to general anaesthesia for anal canal surgery.

Supports low-dose epidural over general anaesthesia for anal surgery; confirms RCT-level advantages for regional techniques.
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.

Kausalya et al. (1994) conducted an RCT in Surgery of the anal canal (n=50). Low-dose epidural anaesthesia vs. General anaesthesia was evaluated on Patient comfort, surgical requirements and anaesthetic safety. Low-dose epidural anaesthesia was a more effective means of providing analgesia and maintaining adequate sphincter tone for anal surgery than general anaesthesia.
