Study summary

Postoperative pain after cesarean delivery is common and affects on both mothers and children.

The goals of this retrospective observational study aim to predict pain score and opioid consumption of index cesarean delivery from pain score and opioid consumption of previous cesarean delivery.

Read the detailed description

The authors will review the medical records of recruited participants for demographic data as well as pain scores and opioid consumption of index cesarean delivery and previous cesarean delivery.

What researchers measure

Primary outcomes

  1. Prediction of pain score after cesarean delivery

    To predict pain score of index cesarean delivery from previous cesarean delivery using pain score measured by verbal numerical rating scale (VNRS) ranging from 0 (no pain) to 10 (worst pain imaginable).

    Time frame: January 2024 - December 2025

Secondary outcomes

  1. Prediction of opioid consumption after cesarean delivery

    To predict opioid consumption of index cesarean delivery from previous cesarean delivery based on 1. number and percentage of patients who required opioid for controlling postoperative pain, 2. MME (milligram morphine equivalent) per total patients and 3. MME per patients who received opioid

    Time frame: January 2024 - December 2025
