Postoperative Pain Management of Caesarean Section
October 19, 2023 updated by: Chi-Hsu Wang, Mackay Memorial Hospital
Postoperative Pain Management of Caesarean Section: a Prospective, Observational Cohort Study
Caesarean section is one of the most frequent surgeries causing severe postoperative pain.
Poor management of acute pain can contribute to postoperative complications, late recovery and the development of chronic pain.
Moreover, it had been demonstrated that the intensity of postpartum pain is associated with depression.
It is imperative to find out appropriate methods of postpartum pain alleviation.
Currently, a lot of analgesic drugs and methods have been developed and used in clinical practice, such as patient-controlled analgesia, extended-release analgesics and multimodal analgesia.
This prospective cohort study is aimed to investigate the outcome of each postoperative analgesic method used in caesarean section.

Detailed Description
This is a prospective, observational, cohort study.
Patients undergoing elective caesarean section will be invited to the study.
The written informed consent will be obtained prior to participation.
After getting the written informed consent, data will be collected from medical records, questionnaires, patient diaries, visit records and telephone visit records.
Through telephone visits, postpartum depression scale and postpartum chronic pain will be evaluated six weeks and three months after delivery.
Demographic data, consumption of analgesics, analgesic methods, intensity of postoperative pain, complications, recovery time, score of depression scale will all be summarized.
Numerical variables will be present with mean and standard deviation and categorical variables will be present with number and percentage.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
IV-PCA group
Patients receiving intravenous patient-controlled analgesia (IV-PCA) will be allocated to IV-PCA group.
|
At the two trial sites, IV-PCA is commonly used with morphine.
The device is installed after delivery and removed within 3 days.
Other Names:
|
IV-PCA + NALDEBAIN group
Patients treated with the combination of IV-PCA and intramuscular injection of dinalbuphine sebacate will be allocated to IV-PCA + NALDEBAIN group.
|
At the two trial sites, IV-PCA is commonly used with morphine.
The device is installed after delivery and removed within 3 days.
Other Names:
Dinalbuphine sebacate is a prodrug of nalbuphine.
With oil-based formulation, the active ingredient releases slowly and the effect lasts longer than nalbuphine.
After delivery, a single 150 mg dose of dinalbuphine sebacate is administered intramuscularly.
Other Names:
|
NALDEBAIN group
Patients injected with dinalbuphine sebacate intramuscularly will be allocated to NALDEBAIN group.
|
Dinalbuphine sebacate is a prodrug of nalbuphine.
With oil-based formulation, the active ingredient releases slowly and the effect lasts longer than nalbuphine.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Postpartum pain intensity
Time Frame: Within 5 days after delivery
|
Pain intensity is assessed by numerical rating scale (NRS) at least twice daily during hospital stay after delivery.
NRS is a 11-point scale which labeled from zero (no pain) to ten (worst pain).
The area under the curve of NRS are calculated.
|
Within 5 days after delivery
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Consumption of analgesics
Time Frame: Within 5 days after delivery
|
The mean total consumption of analgesics during the hospital stay after delivery.
|
Within 5 days after delivery
|
Incidence of complications
Time Frame: Up to 5 days after delivery
|
the incidence of postoperative complication occurring during hospital stay after delivery, especially the ones related to analgesics.
|
Up to 5 days after delivery
|
Ambulation
Time Frame: Up to 5 days after delivery
|
The mean length of time between delivery and the first ambulation.
|

|
Breastfeeding
Time Frame: Up to 5 days after delivery
|
The percentage of participants able to breastfeed during hospital stay and the mean length of time between delivery and the first breastfeeding.
|
Up to 5 days after delivery
|
Gastrointestinal function recovery
Time Frame: Up to 5 days after delivery
|
The mean length of time between delivery and first soft diet.
|
Up to 5 days after delivery
|
Postnatal Depression assessment
Time Frame: At baseline, 6 weeks and 3 months after delivery
|
Edinburgh Postnatal Depression questionnaire is used to assess patients' postpartum depression.
Participants are asked to fill in the questionnaire at baseline (within 30 days prior to delivery), 6 weeks and 3 months after delivery.
|
At baseline, 6 weeks and 3 months after delivery
|
Satisfaction assessed by a four-point scale
Time Frame: 6 weeks after delivery
|
Participants are asked to assess the satisfaction toward rate of recovery progress and pain management through 6 questions six weeks after delivery.
Each question contain 4 choices: very satisfied, satisfied, dissatisfied and very dissatisfied.
|
6 weeks after delivery
|
Chronic pain intensity
Time Frame: 6 weeks and 3 months after delivery
|
Chronic pain intensity is assessed by NRS 6 weeks and 3 months after delivery.
