Abstract

Abstract : ( Can J Anaesth . 2022;69:86–96) Previous studies have shown that programmed intermittent epidural bolus, the automatic delivery of boluses at certain times during epidural analgesia, decreases pain, motor block, and local anesthetic consumption while increasing patient satisfaction. However, unnecessarily high sensory levels have been noted in prior studies. Variables such as patient demographics and characteristics, patient positioning, medication volume, local anesthetic concentration, and injection level have all been researched in relation to epidural spread. The impact of delivery rates on sensory block has not been extensively researched. The aim of this study was to compare injection speeds of 250 mL/h and 125 mL/h administered at 40-minute intervals during the first stage of labor. The authors hypothesized lower delivery speeds would reduce sensory block levels.
