Abstract
Objective To study effects of bupivacaine and morphine combination with infraorbital nerve block on postoperative pain after cleft lip repair operation in paediatric patients.Methods 50 paediatric patients (ASA I) aged from 12 to 60 months undergoing cleft lip repair were randomly divided into two groups,25 cases for each group.After tracheal intubation,group B (using bupivacaine) received bilateral infraorbital nerve block with 1 ml of 0.25％ hupivacaine on each side and group BM (using bupivacaine and morphine combination) received 1 ml of 0.25％ bupivacaine along with 1 μ g/kg body weight morphine.Pain after recovery from anaesthesia was assessed postoperatively using the FLACC scale.Results Physical characteristics of the children studied had no significant differences.The duration of analgesia from the time of administration of block in group B was (20.2 ± 2.6) h compared to (36.8 ± 3.4) h in group BM (P＜0.01).Between two groups,the FLACC scale in group B was higher at 12,24 and 48 h postoperatively than those in group BM (P＜0.01).Conclusion Addition of morphine as an adjunct to local anaesthetic significantly prolongs the duration of postoperative analgesia without any adverse effects.
