We sought to establish normative values of intraabdominal pressure (IAP) in postpartum women with and without arterial hypertension.


Bladder pressure was measured via a Foley catheter 1 hour following completion of cesarean section in supine and semirecumbent positions in 21 patients.


Mean supine IAP (6.4 +/- 5.2 mm Hg) was significantly lower than semirecumbent IAP (11.6 +/- 7.2 mm Hg) (P < .05). Body mass index (BMI) was significantly correlated to IAP regardless of the gestational age (r(2) supine = 0.46, semirecumbent = 0.37; P = .004 for either). Increasing gravidity was associated with decreasing IAP. Patients with arterial hypertension had higher BMI, were delivered earlier, and had higher IAP than patients with normal arterial pressure, either in supine or semirecumbent position. However, these relationships were not significant when results were controlled for BMI.


Postcesarean section IAP is higher than in the general surgical population. Patients with hypertensive disorders have IAPs approaching to intraabdominal hypertension range.
