BackgroundThis study evaluated efficacy, safety and patient satisfaction with incisional analgesia with a subfascial catheter compared to epidural analgesia for pain relief following caesarean section.MethodsForty patients were randomised after elective caesarean section to receive either intermittent 10-mL boluses of 0.125% levobupivacaine into the epidural space and physiologic saline into the surgical wound or intermittent 10-mL boluses of 0.25% levobupivacaine into the wound and epidural saline with a repeated 10-dose regimen. Analgesic efficacy was evaluated by numerical pain scores (0-10, 0=no pain, 10=worst pain) and based on the consumption of supplemental opioid. Side effects, patient satisfaction and plasma concentrations of levobupivacaine were recorded.ResultsIn the epidural group average pain scores were lower (1.8 vs. 3, P=0.006) and the consumption of local anaesthetic (29 mL vs. 38 mL, P=0.01) was smaller during the first four postoperative hours, after which both groups had pain scores of 3 or less at rest. All parturients were able to walk after the 24-h study period. The total consumption of rescue opioid oxycodone (32 vs. 37 mg, P=0.6) during the whole 72-h study period was low in both study groups. Side effects were mild and rare. Satisfaction scores were equally high in the two groups. Peak plasma concentrations of levobupivacaine were below the toxic range.ConclusionIncisional local analgesia via a subfascial catheter provided satisfactory pain relief with patient satisfaction comparable to that seen with epidural analgesia. This technique may be a good alternative to the more invasive epidural technique following caesarean section as a component of multimodal pain management.
