This was a matched case-control cohort study, intended to assess the analgesic efficacy of ultrasound guided interscalene brachial plexus block (US-ISB) in patients to undergo an open reduction and internal fixation (ORIF) of middle or lateral clavicle fracture.
Derived from this study, patients who were given
ultrasound guided interscalene brachial plexus block required less
intraoperative Sufentanil, consumed less opioid equivalents post-surgically.
This was a matched case-control cohort study, intended to
assess the analgesic efficacy of ultrasound guided interscalene brachial plexus
block (US-ISB) in patients to undergo an open reduction and internal fixation
(ORIF) of middle or lateral clavicle fracture.
In this study, fifty consecutive patients reserved for
surgical fixation of middle/lateral clavicle fracture were registered. General
anaesthesia with ISB was administered in these patients. They were compared to
a historical control of seventy-six retrospective patients without regional
block. The primary outcome was post-surgical consumption of overall i.v.
morphine equivalent. Each ISB-treated patient was matched to the patient without
ISB and their differences were evaluated. Matching used a 1-to-1,
nearest-neighbour method via the Mahalanobis metric.
The patients under consideration with ISB displayed
considerably lower i.v. morphine equivalent consumption at 2 postoperative
hours (0.7 mg) as compared to the controls 8.8 mg.
ISB found to provide pain relief following the surgical
fixation of middle and lateral clavicle fracture. The study outcomes can help
surgeons a better analgesic strategy for this type of surgery. Further studies
are needed to recognise the optimal regional technique for medial third
clavicle fractures and the clinically significant contributions of the cervical
and brachial plexus.
