Summary

This trial aims to determine if adding morphine to the spinal component of combined spinal epidural (CSE) can reduce breakthrough pain during labor. Neuraxial analgesia, which includes lum

Who is the study for?
This trial is for women in labor who need pain relief. They should not have any health conditions that would make an epidural risky, such as bleeding disorders or infection at the injection site.
What is being tested?
The study tests if adding a small dose of morphine to the spinal part of an epidural (CSE) can better prevent breakthrough pain during labor compared to using saline solution (placebo). It's a double-blinded study, so neither patients nor doctors know who gets morphine.
What are the potential side effects?
Possible side effects include itching, nausea, respiratory depression (slow breathing), and delayed onset of pain after initial relief. These are common with opioids like morphine but will be closely monitored.
