Overview

0.2% ropivacaine provides comparable post-cesarean TAP analgesia to 0.5%; leaves optimal concentration open for larger trials.

Structured PICO

Does ropivacaine 0.2% provide similar postoperative analgesia compared to ropivacaine 0.5% in transversus abdominis plane block after cesarean delivery?

P
Population
50 parturients with American Society of Anesthesiologists Physical Status I or II aged between 25 and 35 years undergoing cesarean delivery with general anesthesia
I
Intervention
Bilateral 20 ml of 0.2% ropivacaine in transversus abdominis plane (TAP) block at the end of surgery
C
Comparator
Bilateral 20 ml of 0.5% ropivacaine in transversus abdominis plane (TAP) block at the end of surgery
O
Outcome
Intensity of postoperative pain at rest and during movement (Visual Analogue Scale)patient reported

Ropivacaine 0.2% provides similar postoperative analgesia to ropivacaine 0.5% when used in TAP block after cesarean delivery, suggesting the lower concentration is sufficient.
