Background:
Patients with endometriosis are known to have altered pain perceptions. Cesarean delivery (CD) is one of the most prevalent surgeries performed worldwide. Appropriate pain control following CD is clinically important to the recovery and relief of patients. This study assessed pain perception and analgesic use after CD among women with or without endometriosis.
Methods:
This retrospective case control study included women diagnosed with endometriosis, based on clinical or surgical findings, who underwent CD from 2014 to 2022. Controls were matched to the study group by maternal age, BMI (kg/m2), parity, number of previous CDs and by CD indication, in a 2:1 ratio. Post-operative visual analogue scale (VAS) pain scores, on each post-operative day (POD) were compared between groups. Pain intensity was measured and compared using the VAS, range 0 (no pain) to 10 (worst pain). The standard pain relief analgesia protocol in our department includes fixed oral treatment with paracetamol and diclofenac, with the addition of morphine sulphate on POD 0. Analgesic dosages used and the percentage of patients not using the full standard analgesic protocol were compared between groups.
Results:
As compared to controls (n = 142), the endometriosis group (n = 71) was characterized by higher rates of in-vitro fertilization (IVF) pregnancies and previous abdominal surgeries other than CD (p < .001 for both). Other maternal characteristics between groups did not differ. On POD 0, mean morphine dosage was significantly higher in the endometriosis group compared to the control group (24 mg vs. 22.8 mg, respectively; p = .044). More patients in the endometriosis group used the full standard analgesia protocol or more, as compared to controls. VAS scores were not significantly different between groups.
Conclusions:
Increased use of analgesics after CD was more common among women with endometriosis. These findings imply that pain relief protocols should be personalized for women with endometriosis.
