    During delivery (intrapartum)

  • Comparison of quantified blood loss (hemoglobin loss) using the The Triton™

    During immediate postpartum period.

Study Arms (2)

Data Collection Phase 1

All women who had vaginal deliveries between 2010 and 2015 who had a procedure code indicative of transfusion (99.0x) or received a diagnosis suggestive of peripartum hemorrhage (e.g. diagnosis x code 666.xx, 641.x, 645.x, 646.x 674.x).

Data Collection Phase 2

All women who delivered (vaginally) at HackensackUMC who had blood loss and measured quantitatively by Triton and qualitatively (i.e., EBL) by obstetrician.

Eligibility Criteria

Sexfemale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

All women who delivered (vaginally) at HackensackUMC between 2010 and 2015 who had blood loss during the delivery.

You may qualify if:

  • All women who delivered (vaginally) at HackensackUMC who had blood loss and measured quantitatively by Triton and qualitatively (i.e., EBL) by obstetrician.
  • All women who had vaginal deliveries between 2010 and 2015 at HackensackUMC who had a procedure code indicative of transfusion (99.0x) or received a diagnosis suggestive of peripartum hemorrhage (e.g. diagnosis x code 666.xx, 641.x, 645.x, 646.x 674.x).

You may not qualify if:

  • Women who received transfusions unrelated directly to pregnancy (e.g. renal disease, anemia of pregnancy, genetic or viral conditions causing anemia).
