Brief Summary

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

This is an interventional drug trail to evaluate the effect of different intrathecal opioids on post-operative pain experiences in women who have undergone caesarean section surgery.

Detailed Description

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

1. To evaluate the effect of three different intrathecal opioid mixtures on post-operative pain experiences in women who have undergone caesarean section surgery, relating specifically to:

1. Post-operative analgesic requirements at two time points (12 hours and 24 hours) after surgery
2. Pain scores at two time points (12 hours and 24 hours) after surgery
3. Sedation scores at two time points (12 hours and 24 hours) after surgery
4. Post-operative nausea scores at two time points (12 hours and 24 hours) after surgery
5. Post-operative pruritis scores at two time points (12 hours and 24 hours) after surgery
2. To determine the impact that the patients' post-operative pain has on their activities in the first 24 hours after surgery
