Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Epidural analgesia is the gold standard of pain relief for labour pain. Despite this, more than 50% of parturients continue to experience pain leading to suffering and increased caregiver workload. Women who have increased pain tend to have lower successful patient bolus demands when patient controlled epidural analgesia (PCEA) is utilised and have dysfunctional labour requiring obstetric intervention such as Caesarean or instrumental delivery. Labour pain often escalates and worsens as labour progresses requiring an individualized, variable, flexible analgesic regimen. Bolus epidural administrations have been shown to improve uniform spread of local anaesthetics with better pain relief, compared to fixed background infusions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The research team developed two novel epidural delivery regimens: computer-integrated PCEA (CIPCEA) and modified programmed intermittent bolus (MPIB) focused on individualization of analgesic requirements. This phase 3 double-blinded randomized controlled trial will compare the two novel regimens, and each with conventional PCEA with basal infusion (BI), in reducing breakthrough pain (failure of the regimen to provide adequate pain relief, necessitating unscheduled epidural supplementation) incidence as the primary outcome in nulliparous term women requesting labour epidural analgesia. In addition, a discrete choice experiment (DCE) in the format of a survey will be administered to estimate the women's preferences in treatment attributes related to epidural analgesia, including control over epidural dosage, chance of having breakthrough pain, motor block, instrumental delivery and out-of-pocket cost for epidural analgesia. We will also look into the association model for breakthrough pain that would take into account pre-delivery factors to better understand the mechanism of breakthrough pain during labor process.
