Abstract

Objective: The study aimed at finding the mean blood loss following vaginal delivery using calibrated BRASSS-V drape, the average drop in haematocrit at 2hrs and 6hrs following vaginal delivery and the relationship between blood loss estimation using calibrated BRASSS-V drape and pre-weighed perineal pads.

Methods: One hundred eligible parturients were recruited for the study. Calibrated BRASSS-V drape was used to collect blood during vaginal delivery and the quantity read from the calibrated receptacle. Pre-weighed pads were used to collect remnants blood not directly collected by the drape, weighed and equivalence in volume added to that obtained from the drape. The haematocrit was determined at admission in labour after ruling out dehydration, repeated 2hours and 6 hours post-delivery.

Results: The mean value of blood loss following vaginal delivery using calibrated BRASSS-V drape estimation was 261mls and the mean haematocrit drop was 1.36% and 2.50% after 2hrs and 6hrs respectively. A correlation curve was plotted to determine the relationship between measured blood loss and haematocrit drop after 2hrs and 6hrs of delivery and the one at 6hrs correlated better (r=0.487 and r= 0.750 at 2hrs and 6hrs respectively).

Conclusion: There was a positive correlation between the measured blood loss at vaginal delivery and the drop in haematocrit with better correlation at 6hrs. The 6hrs haematocrit drop in well hydrated and selected parturients can be used to estimate blood loss at vaginal delivery in labour ward settings.
