Abstract: The increase in intra-abdominal pressure（IAP） will lead to multiple organ dysfunctions. There will be often complicated with abdominal compartment syndrome（ACS） or intra-abdominal high pressure（IAH），if pregnancy with serious internal medical or surgical diseases，or with serious complications. Furthermore，it will lead to an increased risk of maternal and perinatal mortality. Key measures for the diagnosis and prevention of ACS or IAH is monitoring IAP，the pregnancy maternal normal IAP standards and testing methods are not yet clear，that the bladder pressure method is still the gold standard of detection maternal IAP. For severe maternal IAP monitoring，we should do early detection and early treatment to avoid the occurrence of ACS. Once diagnosis of ACS，we should do early intervention，and the surgical decompression if it proves necessary.

Key words: Abdominal cavity, Pressure, Perinatal care, Abdominal compartment syndrome
