摘要

Abstract Background Intraperitoneal pressure (IPP) counteracts the diversion of cerebrospinal fluid (CSF) from the cranial to the peritoneal compartment during ventriculoperitoneal shunting. Animal studies suggest that the intrinsic IPP exceeds the intraperitoneal hydrostatic pressure. The intrinsic IPP in mobile patients is relevant for shunt therapy, but data about it is not available. Methods The IPP was measured indirectly in 25 mobile subjects (13 female) by applying a standard intravesical pressure measurement technique. Measurements were carried out in reference to the navel (supine position) and the xiphoid (upright position). Results were adjusted for the intraperitoneal hydrostatic pressure and correlated afterward with general body measures. Results The corrected mean (SD) IPP measured in the supine position was 4.4 (4.5) cm H 2 O, and the mean (SD) upright IPP was 1.6 (7.8) cm H 2 O ( p ?=?0.02). A positive correlation was found between the body mass index (BMI) and the IPP in the upright ( r ?=?0.51) and supine ( r ?=?0.65) body positions, and between the abdominal circumference and the IPP in the supine position ( r ?=?0.63). Conclusions The intrinsic IPP in mobile subjects exceeds the intraperitoneal hydrostatic pressure. Thus, the intrinsic IPP counteracts the diversion of CSF into the peritoneal compartment. The intrinsic IPP is correlated with mobile patients’ general body measures.
