Study Summary

Neuraxial narcotics are commonly used in obstetric patients for cesarean delivery to help with pain control over the first 24 hours after the surgery. The aim is to evaluate effectiveness of promethazine (IMP) treatment of intrathecal morphine induced pruritus (ITIMIP). A treatment for ITMIP, other than naloxone, will allow for increased use of intrathecal narcotics and decrease the use of systemic opioids in the initial post-operative period.

Primary Outcome

Pruritus (itching) will be quantified by the ItchyQuant Scale. The ItchyQuant scale is a 0 -10 scale with 0 denoting no itch and 10, the worst itch possible. Participants were asked at 3 different time points (1 hour, 4 hours and 24 hours) after surgery to rate their itching. In the results here we reported any itching (a score greater than zero on the ItchyQuant scale) at 24 hours after surgery in each group.
