[Use of the pulmonary artery catheter (Swan-Ganz) in severe eclampsia]. / Izpolzvane na pulmo-arterialen katetur (Swan-Ganz) pri tezhka preeklampsiia.

The use of a balloon-tipped, flow-directed pulmonary artery catheter in critically ill and surgical patients was introduced in the mid-1970s. The purpose of this paper is to review experience with the pulmonary artery catheter in subsets of women with severe preeclampsia. Most reports have been observational in nature, elucidating hemodynamic profiles and effects on these profiles of therapeutic treatment.

[Influence of maternal position during delivery of fetal oxygen saturation]. / Vliianie polozhenieto na razhdashtata v'rkhu kislorodnata saturatsiia na ploda.

The aim of the study is to investigate the alterations in fetal oxygen saturation during right lateral, supine and left lateral maternal position. Thirty six women at term are included--during the first stage of normally progressing labour. Simultaneous monitoring is carried out of fetal heart rate, uterine contractions, fetal oxygen saturation and maternal arterial blood pressure for a certain period of time in different maternal positions. It was established, that fetal oxygen saturation values are lowest in the supine position, still remaining in physiological ranges--47.1 +/- 10.2. If supine syndrome develops, fetal oxygen saturation values decrease significantly: 23%, 25%.

[Ultrasonic methods for determining the volume of amniotic fluid in a complicated pregnancy: improved methods for the prognosis of the perinatal outcome]. / Ultrazvukovi metodi za opredeliane na obema na okoloplodnata technost pri uslozhnena bremennost: usuvurshestvani metodi za prognozirane na perinatalen izkhod.

Semiquantitative measurement of amniotic fluid volume (AFV) was used to predict the pregnancy outcome. In 229 high risk pregnancies, the AFV was assessed by 4 ultrasonographic methods, including our suggested one--the modified amniotic fluid index (MAFI). Abnormal perinatal outcome was defined as operative delivery sue to fetal distress (OD/FD), meconium passage, low 5 min. Apgar score, umbilical artery pH (< 7.2) and intrauterine growth retardation (IUGR). About 26.2%, 32.8%, 37.6%, 30.6% and 16.6% cases of OD/FD, meconium stained fluid, low 5 min. Apgar score, low pH and IUGR were identified with oligohydramnios compared with the normal fluid group, using MAFI (p < 0.000001). The MAFI showed higher significance than the other ultrasonographic (US) methods. With the relative screening performance the sensitivity of MAFI, amniotic fluid index (AFI), maximum vertical pocket (MVP) and tho-diameter pocket (TDP) depths were 91.9%, 70.2%, 58.9% and 32.8% respectively with OD/FD. Our results suggest that the AFV assessment by MAFI may be superior to the other US techniques and it may used in the testing protocols of antepartum fetal surveillance.

[Assessment of oxygen delivery (DO2) and oxygen consumption (VO2) in severe pre-eclamptic patients]. / Otsenka na kislorodniia pritok (DO2) i kislorodnata konsumatsiia (VO2) pri patsientki s tezhka preeklampsiia.

We compared the results of oxygen delivery and oxygen consumption measurements in 11 preeclamptic patients and report of the oxygen transport in severe preeclampsia. Measurements were performed between 28-36 weeks of gestation.

We compared the results of Swan-Ganz measurements in 11 preeclamptic women and report of the hemodynamic profile in severe preeclampsia. Measurements were performed between 28-36 weeks of gestation.
