PLR in a Good Helath After 24 Week of Preganancy

Status Not yet recruiting

Clinical Trial Summary

fluid resuscitation is one of the bases of strategies in ICU to take in charge patients , one of the technique to evaluate preload charge , is Passive leg raising, that allows reliable prediction of fluid responsiveness even in patients with spontaneous breathing activity or arrhythmias . In recent years, hemodynamic response to passive leg raising (PLR) has been popularized as a dynamic test of preload responsiveness [1]. This manoeuvre provides an "auto-fluid challenge" which is rapid, transient and reversible. PLR transfers blood contained in the venous reservoir of the lower extremities to the central venous compartment leading to a transient increase in preload and an increase in cardiac output by Frank-Starling mechanism in preload responsive individuals. untille now the usseuful of PLR in Pregnancy, and also The validity of dynamic measurements of preload to predict fluid response during pregnancy are note clear in littérature .

Clinical Trial Description

A total of 108 low-risk pregnant women and 54 healthy non-pregnant controls, aged >18 years, participated in the study. Pregnant women attending for the second trimester routine ultrasound screening at 17-19 weeks of gestation were informed about the study and invited to participate if they had a low-risk pregnancy and ultrasound scan did not show any fetal or placental abnormality. Those who agreed were consecutively enrolled and an appointment was made for functional hemodynamic evaluation at 22-24 weeks of gestation. Exclusion criteria were any pre-existing medical condition that may have an effect on the course of pregnancy, and a previous history of preeclampsia, gestational diabetes, intrauterine fetal growth restriction or preterm delivery. Non-pregnant controls were recruited among the nursing, administrative and laboratory staff of the hospital and university. Healthy women of reproductive age were asked to attend for hemodynamic assessment during the follicular phase between day 5 and 10 of the menstrual cycle. Women with a previous history of pregnancy complication and those with a known disease or on regular medication were excluded. Examination was performed, ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
