Abstract

PURPOSE: A multimodal analgesic approach is necessary for post-thoracotomy pain, which can be severe. Intravenous access, central and peripheral nerve blocks are frequently used. The aim of this study was to evaluate the efficacy of serratus anterior plane block (SAPB) in the management of post-thoracotomy pain.

METHODS: A total of 40 patients who underwent thoracotomy between January 2014 and January 2016 were retrospectively analyzed. The patients were divided into two groups: Group M (intravenous patient-controlled analgesia morphine; n = 20) and Group S (intravenous patient-controlled analgesia morphine + SAPB; n = 20). The Visual Analogue Scale (VAS) was used for pain evaluation at the 1st, 2nd, 4th, 6th, 8th, 12th and 24th postoperative hours and morphine consumption was evaluated at the 6th, 12th and 24th postoperative hours. Secondary outcomes were additional analgesic requirement, side effects, the Ramsay Sedation Scale (RSS) scores, block onset time and block level.

RESULTS: The VAS scores and the amount of morphine consumed at the 6th, 12th and 24th hours were found to be significantly lower in Group S than in Group M (P < 0.001). No statistically significant difference was found in the rate of side effects, including nausea, vomiting, pruritus, respiratory depression, bradycardia and hypotension, and RSS outcomes between the groups.

CONCLUSION: Our study suggests that SAPB is an effective adjuvant treatment option for thoracotomy analgesia.
