Objectives: The aim of this study was retrospective analysis of arterial hypertension during pregnancy in the Department of Obstetrics and Perinatology of Pomeranian Academy of Medicine in Szczecin, and severe PIH intensive obstetrical care optimization.
Design: The retrospective analysis of 81 pregnancies complicated by arterial hypertension in the years 1995-2000 was performed.
Material and methods: The retrospective analysis of 81 pregnancies was performed. Patients were divided into two groups. In the first pregnancy was ended by caesarean section (n = 43), in the second by vaginal delivery. The mean gestational age, the way of delivery, accompanying diseases, uric acid levels, short term variability, Dawes - Reedman's criteria, presence of decelerations in CTG, Doppler PI, S/D, RI parameters in umbilical artery and cerebral arteries, presence of AEDVF and REDVF in umbilical artery were analyzed.
Results: Caesarean section was performed in 53.1% of all cases, in 46.9% vaginal delivery took place. Absolute range of short-term variability was more often less than 6 ms in caesarean section group (41.9%). Uric acid level was also higher in caesarean section group (p = 0.000194)
Conclusions: 1. The caesarean rate in pregnancies complicated by arterial hypertension is over 50% and during severe PIH is approximately 100%. 2. Caesarean section takes place before estimated delivery date and indications to it are in most cases connected with a main disease 3. Short-term variability is lower among patients from caesarean section group. 4. Uric acid level is a relevant parameter of a degree of arterial hypertension, and the level is higher in first group. 5. Doppler velocimetry of umbilical artery and middle cerebral artery are valid part of obstetrical care among patients with PIH.
