7 Clinical Trials for Various Conditions
To establish if placental transfusion, using deferred cord clamping for 60 seconds or more while holding the baby at or below the level of the placenta, will improve survival without disability compared with standard early cord clamping in preterm babies less than 30 weeks of gestation.
The American College of Obstetrics and Gynecology, American Academy of Pediatrics and the World Health Organization have recently published recommendations related to placental transfusions in preterm infants. This project will review outcomes of preterm infants following a quality improvement implementation process in several delivery centers in Indiana. Centers involved in this project are also part of the Indiana Vermont Oxford Network (IRB#1003-84). Data is recorded for that network and the investigators site will be reviewing that data every 3 months from infants who have completed the Vermont Oxford Network collection. This project will specifically look at the incidence of intraventricular hemorrhage, necrotizing entercolitis, periventricular leukomalacia, sepsis and death following the implementation of the ACOG recommendations.
The proposed study is a pilot prospective controlled trial to measure the blood volume left in the placenta after varying cord clamping times when the infant is placed skin-to-skin on the maternal abdomen. Delaying cord clamping has been shown to decrease anemia in infants. However, the best way to get the most blood to the baby is not known. The practice of cord clamping at birth is not the same among doctors and midwives and we do not know the effect of putting he baby on the mother's abdomen.
To determine whether performing extended delayed cord clamping in term neonates that require resuscitation improves early transition as compared to short-delayed cord clamping.
Delayed cord clamping (DCC) from 30 to 60 seconds allows blood to continue to flow from the placenta through the umbilical cord to the infant, thus resulting in a placental transfusion. This transfusion may improve circulating volume at birth leading to a smoother postnatal transition and overall improved outcome for preterm infants. The average blood volume delivered with DCC up to 90 seconds in preterm infants has been estimated to be about 12 ml per kg with vaginal deliveries resulting in slightly higher transfusions compared to cesarean deliveries. Several several short-term benefits have been described including a reduction in the need for blood transfusions as well as a possible reduction in intraventricular hemorrhage and necrotizing enterocolitis. All mothers with threatened preterm delivery between 28 and 34 6/7 weeks will be approached for the study. Following consent, the infant will be randomly assigned to either a 30 or 60 second delay in cord clamping in the delivery room. If the infant is not breathing by 30 seconds, the cord will be clamped and the infant moved to a resuscitation area. The primary outcome is a 3 percent difference in the hematocrit at one hour (routinely obtained on all babies). With approximately 75 neonates in each group (30 and 60 second DCC), there is 80% power to detect a difference in the mean hematocrit of 3% using a two-sample t-test with a 0.05 two-sided significance level.
The purpose of this pilot study is to determine if umbilical cord milking at the time of scheduled cesarean section effects the hemoglobin and hematocrit levels of full-term infants as determined by hemoglobin and hematocrit levels at 36-48 hours of life. This study will help to establish the feasibility of umbilical cord milking as an alternative to delayed clamping at the time of planned cesarean section.
The purpose of this study is to evaluate the efficacy of KARL STORZ curved fetoscope (11508AAK) and its straight version (11506AAK) for laser photocoagulation of placental anastomoses in patients with an anterior placenta and Twin to Twin Transfusion Syndrome (TTTS).
