Measuring cardiac changes using electrical impedance during delayed cord clamping: a feasibility trial.

ABSTRACT:

Background

To date no study has attempted to continuously evaluate changes in hemodynamics during delayed cord clamping in humans. We aimed to demonstrate 1. the feasibility of measurements of hemodynamics during delayed cord clamping and 2. to describe the changes that occur over each minute.

Results

After vaginal delivery, term infants (37(0)-41(6) weeks) were placed on a Life Start® bed 10-20 cm below the placenta. Transcutaneous sensors were placed on the neck and chest to determine heart rate, stroke volume and cardiac output at each beat. Once a signal was obtained, first 5 values (taken every beat) were averaged and the percent change for each subject from baseline was calculated. 20 infants were enrolled and all had a reliable signal obtained from transcutaneous sens
