ABSTRACT

ObjectiveTo study the mechanism of hyperbaric oxygen (HBO) on treatment of the late-onset fetal growth restriction (FGR). MethodsSixty-one pregnant women, who were first diagnosed as FGR after 32 weeks, were voluntarily devided into group-A (Routine management, n=28) an d group-B (HBO combined with routine management, n=33). Thirty cases of normal pregnant women were served as control group, called group-C (n=30).Results(1)Before treatment, the values of umbilical artery systolic/diastolic Ratio (S/D), pulse index (PI), resistant index (RI) and the blood viscosity at the low shear rate (LBV) of both group-A and group-B were significantly higher than those of group-C, P
