About

This is a pilot study of delayed cord clamping (DCC) at progressively longer intervals (90 to 120 seconds) during elective cesarean deliveries of term infants. The investigators hypothesize that the pilot trial of DCC in cesarean sections will demonstrate safety of this procedure for mothers and babies.

Full description

Despite expert recommendations to delay clamping the cord for at least 2 minutes, early cord clamping remains a common obstetrical practice. The World Health Organization has noted that data on cesarean deliveries are more limited, particularly with respect to long-term effects in infants. Recently, the American College of Obstetrics and Gynecology also noted in a committee statement that " the ideal time for clamping of the umbilical cord in cesarean section vs. vaginal birth is a particularly important area for future research".

The objective of this study is to conduct a pilot trial of delayed cord clamping during cesarean deliveries to determine if progressively longer intervals of cord clamping are feasible and not related to poorer maternal and neonatal outcomes as compared to outcomes from historical controls. We will offer study entry for women planning elective cesarean delivery to collect prospective data on progressively longer intervals, analyzing outcomes for each time interval to ensure they are clinically acceptable, prior to extending the interval another 30 s. We anticipate approximately 20 women at each interval (90 and 120 sec) and will perform hemoglobin analysis on the infants specifically for this study. If intraoperative blood loss is clinically deemed excessive, or mother or baby are unstable, the cord will be clamped.

Enrollment: 41 patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria:Subjects that are pregnant (women 18 years of age and older) and scheduled for an elective C-section at ≥ 37 weeks gestation will be eligible for the study.

Exclusion Criteria:

Pregnant women that do not plan on having a C-section and individuals that are not pregnant. Pregnant women that are medically unstable, have poorly controlled diabetes mellitus, multiple gestations, anomalous fetuses and/or severe intrauterine growth retardation will be excluded. Adults unable to consent will not be included

Trial design

41 participants in 2 patient groups

90 seconds DCC

Description:

the initial 15-20 subjects (15 enrolled subjects who complete study) will have cord clamped at 90 seconds. Then data will be analyzed and evaluated by DSMB

Two minutes DCC

Description:

If Data Safety Monitoring Board (DSMB) concurs, DCC will then be practiced for 2 minutes for second group, which is the minimum amount of time recommended to be defined as DCC.
