Randomized comparison between epidural waveform analysis through the needle versus the catheter for thoracic epidural blocks.

Background: Epidural waveform analysis (EWA) provides a simple confirmatory adjunct for loss of resistance (LOR): when the needle/catheter tip is correctly positioned inside the epidural space, pressure measurement results in a pulsatile waveform. Epidural waveform analysis can be carried out through the tip of the needle (EWA-N) or the catheter (EWA-C). In this randomized trial, we compared the two methods.

A basic anesthesia training program for nurses in Chad: first steps for a south-south academic cooperation program.

Purpose: Safe perioperative care remains a large public healthcare problem in low- and middle-income countries. Anesthesia care provided by trained professionals is one of the essential determinants to address this situation. This article reports the design and implementation of a focused anesthesia educational program for nurses in Chad.
