Randomized Controlled Trial Comparative Study
A randomised controlled trial of shoulder block vs. interscalene brachial plexus block for ventilatory function after shoulder arthroscopy.
The shoulder block may impair ventilatory function and diaphragmatic movement less than the interscalene brachial plexus block. We randomly allocated 30 adults who underwent shoulder arthroscopy under general anaesthesia to ultrasound-guided shoulder block or interscalene block with 20 ml bupivacaine 0.5%. ⋯ The mean (SD) numeric rating scale pain scores at rest after shoulder block were higher than after interscalene block at two postoperative hours, 1.4 (1.2) vs. 0.3 (0.7), p = 0.02, but lower at 24 postoperative hours, 1.3 (1.3) vs. 3.4 (2.3), p = 0.008. Mean (SD) pain scores on movement in the shoulder and interscalene blocks were similar, with respective values of 1.9 (1.9) vs. 0.7 (1.2), p = 0.13 at two postoperative hours and 3.7 (2.3) vs. 5.3 (2.5), p = 0.41, at 24 postoperative hours.

Hemidiaphragmatic paralysis, a frequent complication of the brachial plexus block performed above the clavicle, is rarely associated with an infraclavicular approach. The costoclavicular brachial plexus block is emerging as a promising infraclavicular approach. However, it may increase the risk of hemidiaphragmatic paralysis because the proximity to the phrenic nerve is greater than in the classical infraclavicular approach. ⋯ The incidence of hemidiaphragmatic paralysis is significantly lower with costoclavicular than with supraclavicular brachial plexus block.

Randomized Controlled Trial Comparative Study
Unilateral transversus abdominis plane block and port-site infiltration : Comparison of postoperative analgesic efficacy in laparoscopic cholecystectomy.
To compare the analgesic efficacy of unilateral subcostal transversus abdominis plane (TAP) block with local anesthetic infiltration, applied to the port site in patients undergoing laparoscopic cholecystectomy (LC). ⋯ Unilateral subcostal TAP block was superior to local anesthetic infiltration at port sites after LC, in terms of low opioid consumption. Unilateral subcostal TAP block is recommended as part of a multimodal analgesic protocol.
