چکیده
OBJECTIVE To compare intercostal nerve block before and after rib harvest in terms of mean postoperative pain score and mean postoperative tramadol usage. STUDY DESIGN Randomized controlled trial. PLACE AND DURATION OF STUDY Department of Plastic Surgery, Mayo Hospital, KEMU, Lahore, from January 2011 to July 2012. METHODOLOGY Patients (n = 120) of either gender with ASA class-I and II requiring autogenous costal cartilage graft were inducted. Patients having history of local anaesthetic hypersensitivity and age < 15 years or > 60 years were excluded. Subjects were randomly assigned to pre-rib harvest (group-1) and post-rib harvest (group-2). Local anaesthetic mixture was prepared by adding 10 milliliters 2% lidocaine to 10 milliliters 0.5% bupivacaine to obtain a total 20 ml solution. Group-1 received local anaesthetic infiltration along the proposed incision lines and intercostals block before the rib harvest. Group-2 received the infiltration and block after rib harvest. Postoperative consumption of tramadol and pain scores were measured at 6 and 12 hours postoperatively using VAS. RESULTS Mean age was 31.43 ± 10.78 years. The mean pain scores at 6 hours postoperatively were 1.033 ± 0.609 and 2.4667 ± 0.812 in pre-rib harvest and post-rib harvest groups respectively (p < 0.0001). The mean pain scores at 12 hours postoperatively were 1.45 ± 0.565 and 3.65 ± 0.633 in pre-rib harvest and post-rib harvest groups respectively (p < 0.0001). The mean tramadol used postoperatively in first 24 hours was 169 ± 29.24 mg and 255 ± 17.70 mg in prerib harvest and post-rib harvest groups respectively (p < 0.0001). CONCLUSION Intercostal block administered before rib harvest as preemptive strategy result in decreased postoperative pain scores and narcotic use.

Posterior intercostal nerve block for pain relief after cholecystectomy. Anatomical basis and efficacy.
The human intercostal space has been studied by excision of the posterior part of the rib cage at autopsy, followed by fixation, decalcification, section and staining. Injection of India ink was used to simulate local anaesthetic. At a point 7 cm from the midline, the distance from the posterior aspect of the rib to the pleura averaged 8 mm. The intercostal nerve usually comprises a number of s...
