A Comparison of a Basal Infusion with Automated Mandatory Boluses in Parturient-Controlled Epidural Analgesia During Labor

Abstract

Our study showed that PCEA+AMB reduced analgesic consumption and could be useful as the mode of maintenance for epidural analgesia.

Low Dose Epidural Analgesia During Labor: Comparison Between Patient Controlled Epidural Analgesia with Basal Continuous Infusion and Intermittent Bolus Technique

“…BCI group could be due to feeling of self-control on pain, a finding in agreement with previous results [8].…”

A double-blind randomized controlled trial of patient-controlled epidural analgesia with or without a background infusion following initial spinal analgesia for labor pain

“…It is possible that longer lockout times with no background infusion or small bolus doses may not allow the agents to disperse adequately; several investigations have indicated that the dose and volume of the bolus injection is important for effective PCEA labor analgesia. 16,17 Furthermore, longer lockout times may induce more frequent bolus demands without delivery of agents because the request occurred within the lockout time interval. 14 With the agents and doses used in our study, a 10-min lockout interval when using a continuous background infusion may represent optimal settings for labor analgesia without increasing the total local anesthetic and opioid consumption.…”

Impact of Drug Delivery Systems on Neuraxial Labor Analgesia

“…At our institution, we integrated PCEA with AMB in a one-pump system and studied 42 parturients in early labor who were randomized to receive either a PCEA with continuous epidural infusion (PCEA and CEI at 5 ml/h) or a PCEA with AMB (PCEA and AMB of 5 ml every hour) [28]. To do so, we devised a computer program that enables an ordinary continuous infusion pump to function as a PCEA pump, with the additional ability to deliver mandatory intermittent boluses.…”
