Investigating the Use of Nonloss of Resistance Syringes for Epidural Insertion: Experience on a Mannequin

Abstract

(Int J Obstet Anesth. 2022;52:103595) The Obstetric Anaesthetists’ Association (OAA) announced a supply disruption of the Portex Loss of Resistance (LOR) Syringe, a commonly used tool for epidural catheter insertion. Several studies have shown no difference in epidural insertion success rates when using LOR to saline or air. Other methods for epidural space identification are being considered yet limited research compares specific low-resistance syringes with standard syringes. This study aimed to compare specific LOR syringes with syringes commonly used in epidural insertion.
