Randomized Controlled Trial Comparative Study Clinical TrialBilateral infraorbital block with 0.5% bupivacaine as post-operative analgesia following cheiloplasty in children.
Various studies have shown that bupivacaine nerve blocks provide prolonged post-operative analgesia. We studied the efficacy of a 0.5% bupivacaine infraorbital nerve block as post-operative analgesia in a random, prospective, double blind manner in children undergoing cleft lip repair. Following the induction of anesthesia with ketamine 2-4 mg/kg im, 60 patients, aged 2-13 years, ASA I and II were equally divided: Group A received 1-1.5 ml bupivacaine, 0.5% with 1:200,000 epinephrine; Group B received 1-1.5 ml saline injected into the vicinity of the infraorbital foramina. ⋯ Group A required no other analgesic whereas a total of 17 patients in Group B required analgesic medication starting at four hours post-operatively, (p less than 0.001). Both the nurses and the parents confirmed that those who received infraorbital block were more comfortable than those who did not. One-way analysis of variance indicates that the mean scores for both groups differs significantly at all levels of comparison, (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
