Analgesic Efficacy of Pfannenstiel Incision Infiltration with Ropivacaine 7.5 mgmL for Caesarean Section

Abstract EN

Background.

Pain after Caesarean delivery is partly related to Pfannenstiel incision, which can be infiltrated with local anaesthetic solutions.

Methods.

A double- blind randomized control trial was designed to assess the analgesic efficacy of 7.5 mg/mL ropivacaine solution compared to control group, in two groups of one hundred and forty four parturients for each group, who underwent Caesarean section under spinal anaesthesia: group R (ropivacaine group) and group C (control group).

All parturients also received spinal sufentanil (2.5 μg).

Results.

Ropivacaine infiltration in the Pfannenstiel incision for Caesarean delivery before wound closure leads to a reduction of 30% in the overall consumption of analgesics (348 550 mg for group R versus 504 426 mg for group C with P<.05), especially opioids in the first 24 hours, but also significantly increases the time interval until the first request for an analgesic (4 h 20 min ± 2 h 26 for group R versus 2 h 42 ± 1 h 30 for group C).

The P values for the two groups were: P<.0001 for paracetamol, P<.0001 for ketoprofen and P for nalbuphine which was the most significant.

There is no significant difference in the threshold of VAS in the two series.

Conclusion.

This technique can contribute towards a programme of early rehabilitation in sectioned mothers, with earlier discharge from the post-labour suite.
