Ultrasound-guided Block of the Brachial Plexus Using Prilocaine: Effects of Local-anesthetic Dose Reduction on Parameters of Block Quality and Adverse Effects in Outpatients
In Brief
A Phase 4 clinical trial evaluating midazolam and prilocaine 1% for Other Surgical Procedures. Completed, enrolled 120 participants.
Detailed Summary
Clinical aim: Does reducing the dose of local anesthetic in ultrasound-guided axillary plexus anesthesia have any effect on the success rate and additional parameters of block quality? Methodology: In this prospective cohort study three groups of 40 outpatients each were administered dosages of 1% prilocaine of either 40mL, 30mL or 20mL for axillary plexus anesthesia. Met-Hb was measured prior to administration of the block and then hourly until the Met-Hb concentration fell. Parameters of block quality and any adverse effects were recorded. The level of significance was defined with α ≤ 0.05.

Timeline
Interventions
Prior to performing the regional anesthesia the investigators administered midazolam as a premedication by mouth (3,75-7,5mg) or intravenously (2-3mg).
40 outpatients : 40ml prilocaine 1% were administered for axillary plexus block
40 outpatients : 30ml prilocaine 1% were administered for axillary plexus block
40 outpatients : 20ml prilocaine 1% were administered for axillary plexus block
