RESUMO
OBJECTIVE: To determine the baseline intraabdominal pressure (IAP) in pregnant women at term. STUDY DESIGN: Pregnant women at term undergoing scheduled cesarean delivery in the absence of labor had IAP measured via an intravesical catheter. Abdominal pressures were obtained in the dorsal supine position with a leftward tilt after the placement of spinal anesthesia. Measurements were taken immediately before and after cesarean delivery. RESULTS: One hundred subjects were included in this Institutional Research Board-approved study. The median preoperative IAP measurement was 22 mm Hg, and the median postoperative IAP measurement was 16 mm Hg. The decrease in the IAP from the preoperative to the postoperative measurement was statistically significant (p < 0.0001). CONCLUSION: The median IAP measurement for pregnant patients at term is 22 mm Hg and is followed by a statistically significant decline after delivery.
