[Morbidity regularity of severe complications of hypertensive disorder complicating pregnancy in clinics].

OBJECTIVE

To analyse incidence of the severe complications of hypertensive disorder complicating pregnancy and the influence on the outcome of pregnancy.

METHODS

A retrospective study of 4107 cases among 71 020 cases who delivered in hospitals from 1995 to 2004 in Guangzhou was conducted.

RESULTS

The morbidity of hypertensive disorder complicating pregnancy was 5.78%, in which the morbidity of severe pre-eclampsia was 27.78% (1141/4107), of mitis pre-eclampsia was 72.22% (2966/4107). Maternal mortality rate was 0.19% (8/4107), and the specific mortality rate was 11.26/100 000. The proportion of severe complications of hypertensive disorder complicating pregnancy from high to low was as follows: placental abruption 1.68% (69/4107), DIC 1.36% (56/4107), hypertensive disorder complicating pregnancy induced cardiopathy (induced cardiopathy) 1.05% (43/4107), renal failure 0.97% (40/4107), cerebrovascular accident 0.58% (24/4107), and hemolysis, elevated liver enzymes and low platelet (HELLP) syndrome 0.51% (21/4107). Mortality caused by severe complications of hypertensive disorder complicating pregnancy were as follows: cerebrovascular accident 17% (4/24), HELLP syndrome 10% (2/21), DIC 5% (3/56) and induced cardiopathy 2% (1/43). The proportion of perinatal mortality from severe complications were as follows: placental abruption 43% (33/77), HELLP syndrome 42% (10/24), DIC 34% (22/64), renal failure 25% (11/44), cerebro vascular accident 24% (6/25) and induced cardiopathy 16% (8/49).

CONCLUSIONS

(1) The morbidity of severe complications from high to low are: placental abruption, DIC, induced cardiopathy, renal failure, cerebro vascular accident and HELLP syndrome. (2) The main causes of mortality for gravida and puerperant are: cerebro vascular accident, HELLP syndrome, DIC and induced cardiopathy. (3) The major complications harmful to perinatal newborns are in the order of: placental abruption, HELLP syndrome, DIC, renal failure, cerebro vascular accident and induced cardiopathy.
