Effect of age of gravida on post-cesarean section pain: An observational study

Objective: Preoperative identification of women at greater risk of post-cesarean pain might allow more intensive analgesic interventions. This study aimed to assess the effect of age of a parturient on post-cesarean section (CS) pain. Methods: 100 pregnant females were enrolled and divided into 4 groups: group A (age 18-24 years), group B (25-30 years), group C (31-35 years), and group D (≥36 years). Patient-controlled epidural analgesia was started postoperatively in all patients. Pain on a 0- to 10-point visual analog scale (VAS), a number of attempts tried for patient-activated dose delivery of ropivacaine, and successful delivery of patient-activated dose of ropivacaine were recorded for 72 hours. Breastfeeding was initiated as early as possible. The effect of breastfeeding on post-CS pain was observed for 72 hours in terms of increase, decrease, or no change in VAS scores with breastfeeding. Results: The peak VAS scores over 72 hours were 4.10 ± 0.60, 4.00 ± 0.67, 3.75 ± 0.45, and 3.42 ± 0.67, respectively, in groups A, B, C, and D, showing a significant declining trend (P = 0.007). The mean VAS scores decreased from 4.08 to 1.69 (group A, P < 0.0001), from 4.00 to 1.64 (group B, P < 0.0001), from 3.67 to 1.25 (group C, P < 0.0001), and from 3.33 to 1.50 (group D, P < 0.0001) over 72 hours. A statistically significant decline in patient-activated rescue drug delivery attempts, the number of times the rescue analgesic was delivered, and 24-h cumulative ropivacaine dose requirement was seen. Conclusions: In this study, it was found that post-cesarean pain decreases significantly with increasing age, as evidenced by reduced pain scores, reduced attempts at rescue drug delivery, and reduced rescue analgesic requirements.
