Filter by:Background: Children with microtia complain of severe postoperative pain during early postoperative days after rib cartilage harvest for auricular reconstruction. The purpose of this study was to compare the analgesic efficacy of intercostal nerve block (ICNB) and paravertebral block(PV) for preventing postoperative pain after rib cartilage graft for auricular reconstruction in children with microtia. Methods: In this prospective randomized study, 144 children will be enrolled in this study and randomized into 3 groups:48 patients will received ultrasound-guided ICNB(UG-ICNB group);48 patients will receive ICNB under direct vision (DV-ICNB group) and 48 patients will receive paravertebral block(PV group) undergoing postoperative pain control using either preventive ICNB followed by catheter-based infusion (33 patients, study group) or intravenous (IV) analgesia alone (33 patients, control group). ICNB will be performed by injecting 1% lidocaine plus 1/200000 epinephrine 3ml into each of three intercostal spaces before perichondrial dissection. PV will be carried out by injecting 1% lidocaine plus 1/200000 epinephrine 9ml into T7 paravertebral space just after induction of anesthesia.before wound closure.Each patient receive patient-controlled intravenous analgesia(PCIA) after surgery.Severity of pain,nausea,vomiting and other side effects would be assessed for the postoperative period of 48 hours.
The erector spinae plane block is a novel regional anesthetic technique that allows for analgesia of the thorax and abdomen with a peripheral nerve block. This study is being performed to assess the effectiveness of this technique in reducing post-operative pain scores and opiate requirements in pediatric and adult patients undergoing rib cartilage grafting surgeries.
