A Novel Combined Anesthetic Technique to Improve the Surgical Working Conditions of Lumbar and Thoracolumbar Spine Surgery from a Spine Surgeon's Perspective: A Prospective Randomized Controlled Study.

Study Design: Prospective randomized controlled study.

Purpose: This study aimed to assess the effects of a different combination of anesthetic techniques in lumbar and thoracolumbar spinal surgeries in terms of muscle relaxation and surgical field in addition to hemodynamic parameters.

Overview Of Literature: Adequate relaxation of the erector spinae muscle and good surgical fields are preferred in lumbar spine surgeries.

Observational study of the efficacy of supraclavicular brachial plexus block for arteriovenous fistula creation.

Background And Aims: Arteriovenous (AV) fistula surgery is commonly performed for AV access for hemodialysis. However the ideal anaesthetic technique of choice remains debated. We aimed to assess operative conditions, vascular patency, and complication rate following AV fistula surgery with isolated brachial plexus block among end-stage renal disease (ESRD) patients.
