Summary

This study tested two doses of spinal morphine (75 vs 100 micrograms) in 240 women having planned C-sections to see which provides better pain control with fewer side effects. Pain was measured using a standard scale over 24 hours after surgery. The goal is to find the best dose to improve recovery and comfort for new mothers.

What this could lead to
If successful, this could help doctors choose the safest, most effective dose of spinal morphine for pain relief after C-sections, improving recovery for mothers.
What could go wrong
This is a small, completed Phase 4 trial with 240 participants, so results may not apply to all patients. The difference between doses may be small, and side effects like nausea or itching are possible.
