Ultrasound-guided interscalene block combined with intermediate or superficial cervical plexus block for clavicle surgery: A randomised double blind study
This study aims to delineate the relative effectiveness between interscalene brachial plexus block with either intermediate cervical plexus or superficial cervical plexus block (CPB) as the anaesthetics for clavicular surgery.
DESIGN
A randomised, double-blind prospective study.
SETTING
Single-centre, tertiary care medical college and research institute.
PATIENTS
Fifty patients with American Society of Anesthesiologist's (ASA) grade I to III, aged 18 to 70 years, scheduled for clavicular surgery, during May 2018 to April 2019 were enrolled in this study.
INTERVENTION
All patients received interscalene block with 10 ml of 0.5% bupivacaine. Patients were randomised to undergo additional ultrasound-guided intermediate CPB (Group-1) or superficial CPB (Group-2) with 10 ml of 0.5% bupivacaine.
MAIN OUTCOME MEASURES
The block success rate, sensory block onset time, haemodynamic parameters, duration of postoperative analgesia and complications were noted. Categorical data were analysed using the chi-square test and Fisher's exact test. Continuous data were analysed using Student's t-test.
RESULT
In Group 1, block success was 100%. In Group 2, five patients failed to achieve adequate surgical anaesthesia (P = 0.02). The average sensory block onset time in Group 1 was 2.5 ± 0.4 min and was longer in Group 2, 4.3 ± 0.5 min (P
