The effect of intra-abdominal pressure on sensory block level of single-shot spinal anesthesia for cesarean section: an observational study

Abstract

Background: Increased intra-abdominal pressure in pregnancy is thought to affect intrathecal drug spread. However this assumption remains largely untested. The aim of this prospective study was to evaluate the association between intra-abdominal pressure and maximum sensory block level in parturients receiving spinal anesthesia for cesarean section.
