Postoperative analgesic efficacy of different volumes and masses of ropivacaine in posterior brachial plexus block.

Background And Objectives: The efficacy of posterior brachial plexus block for shoulder surgeries is demonstrated by different authors. However, there is no consensus on the ideal mass and volume of local anesthetic to be employed. The objetive of this study was to compare different volumes and masses of ropivacaine in posterior brachial plexus block in arthroscopic surgeries of the shoulder.

Comparative study for the postoperative analgesic efficacy of 20 mL at 0.5, 0.75, and 1% ropivacaine in posterior brachial plexus block.

Background And Objectives: Arthroscopic shoulder surgeries are associated with severe postoperative pain. Among the analgesic techniques available, brachial plexus block has the best results. The objective of this study was to determine which concentration of local analgesic used in the posterior brachial plexus block provides longer postoperative analgesia.

[A comparative study on the postoperative analgesic efficacy of 20, 30, or 40 mL of ropivacaine in posterior brachial plexus block.].

Background And Objectives: Arthroscopic surgeries of the shoulder are accompanied by severe postoperative pain. Among the analgesic techniques, brachial plexus block offers the best results. The objective of this study was to determine which volume of local anesthetic in the posterior brachial plexus block offers more adequate analgesia for those procedures.

[Prevalence of diaphragmatic paralysis after brachial plexus blockade by the posterior approach with 0.2% ropivacaine.].

Background And Objectives: Brachial plexus blockade by the interscalene approach, described by Winnie, is one of the most effective techniques in promoting postoperative analgesia in surgeries of the shoulder. Diaphragmatic paralysis is one of the consequences of this technique. This paralysis can cause respiratory failure in patients with prior lung dysfunction.

[Radiological evaluation of the spread of different local anesthetic volumes during posterior brachial plexus block.].

Background And Objectives: Local anesthetic spread during interscalenic block has been thoroughly studied, however there are few studies on posterior block. This study aimed at evaluating the spread of different local anesthetic volumes during posterior brachial plexus block using contrasted X-rays.

Methods: Participated in this study 16 patients submitted to posterior brachial plexus block, 15 of whom were randomly divided in three groups of five patients: Group 1: 20 mL; Group 2: 30 mL.
