Abstract
Transversus abdominis plane (TAP) block is used to provide analgesia after lower
abdominal surgery operations. TAP block has been shown to reduce postoperative pain scores and side
effects of opioids after cesarean section. Generally, TAP block was introduced after cesarean section.
It is assumed that delivery affects sonographic characteristics of the abdominal wall. For this reason,
ultrasonographic measurement of the anatomy of the region defined for TAP block was performed
before and after cesarean section. It was aimed to determine the estimated TAP block distance in the
population undergoing cesarean section. Fifty patients who underwent cesarean section in the operating
room were included in the study. The inclusion criteria were ASA score I-II, age 18-45 years,
gestational age ≥32 weeks, and cesarean section performed by Pfannenstiel incision. Data on patient
age, weight, height, body mass index, gravidity, parity, gestational age (weeks), concomitant disease and
allergy were recorded. According to the results obtained in the study, ultrasound should be performed
if TAP block is accessible. Before cesarean section, the external oblique muscle and internal oblique
muscle are closer to surface than after cesarean section since the TAP distance after pregnancy will be
deeper. Systematic data on ultrasonographic anatomy of the abdominal wall in pregnant women have
not yet been published. The obstetric anesthesiologist should be aware of these changes when planning
a TAP block in the context of cesarean section. There is a need for larger prospective studies.
