Objectives
Narrative objectives1 It is known that pediatric strabisumus surgery is accompanied by strong post-operative pain which causes the distress and abnormal behavior and also delayed discharge.
Although Sub-Tenon's block is normally used as regional anesthesia for adult, It is reported that Sub-Tenon's block is also useful as post-operative analgesia of pediatric strabismus surgery under general anesthesia. But there is no report which shows that the effect of Sub-Tenon's block is depending of the kind of the local anesthetic. we compared the post-operative pain after Sub-Tenon's block with 0.75% ropivacaine and 2% lidocaine at the conclusion of the operation.
