Persistent pain after caesarean section and vaginal birth: a cohort study

Area of Science:

• Obstetrics and Gynecology
• Pain Medicine
• Reproductive Health

Background:

• Post-surgical persistent pain is recognized, but data on delivery-related pain is limited.
• Understanding persistent pain after caesarean section (CS) versus vaginal birth (VB) is crucial for maternal health.
• This study investigates the incidence and characteristics of persistent pain following different delivery modes.

Purpose of the Study:

• To compare the incidence of persistent pain one year after caesarean section versus vaginal birth.
• To analyze the nature and intensity of persistent pain in relation to delivery mode.
• To identify risk factors associated with persistent pain post-delivery.

Main Methods:

• A survey was administered to 600 Finnish-speaking women within one year of childbirth.
• Data collected included health and obstetric history, previous pain experiences, delivery details, and current pain status.
• Statistical analysis compared pain prevalence between CS and VB groups and identified correlations.

Main Results:

• Persistent pain one year postpartum was significantly higher after CS (18%) than VB (10%).
• Previous pain history, prior back pain, and chronic disease were associated with increased persistent pain.
• Higher pain intensity on the day after delivery correlated with persistent pain at one year.

Conclusions:

• Caesarean section is associated with a higher incidence of persistent pain one year postpartum compared to vaginal birth.
• Pre-existing pain conditions and acute postpartum pain are significant predictors of long-term pain.
• Further research into pain management strategies for at-risk populations is warranted.
