[Ultrasound-guided selective nerve blocks for trigger finger surgeries to maintain flexion/extension of fingers - Case series].

Background: A patient's ability to move his/her fingers during hand surgery may be helpful to surgeons because it allows the effectiveness of the intervention evaluation and prediction of hand function in the postoperative period. The purpose of this case series is to demonstrate the efficacy of an ultrasound-guided peripheral nerve block technique to maintain the hand flexor and extensor muscles motor function and discuss the benefits of the technique for trigger finger surgery.

Case Report: Ten patients scheduled to undergo trigger finger surgery were selected.

[Randomized prospective study of three different techniques for ultrasound-guided axillary brachial plexus block].

Introduction: Randomized prospective study comparing two perivascular techniques with the perineural technique for ultrasound-guided axillary brachial plexus block (US-ABPB). The primary objective was to verify if these perivascular techniques are noninferior to the perineural technique.

Method: 240 patients were randomized to receive the techniques: below the artery (BA), around the artery (AA) or perineural (PN).
