Area of Science:

  • Obstetrics and Gynecology
  • Hematology
  • Reproductive Physiology

Background:

  • Platelet activation is known to increase during labor.
  • Previous research has not comprehensively evaluated platelet function changes throughout the labor process and postpartum period.

Purpose of the Study:

  • To investigate dynamic changes in platelet count, volume, and function during different stages of labor and 24 hours postpartum.
  • To compare platelet function in laboring women with healthy non-pregnant controls.

Main Methods:

  • Prospective study involving 25 healthy women undergoing spontaneous vaginal delivery.
  • Blood samples collected during latent phase, active phase, second stage of labor, and 24 hours postpartum.
  • Platelet function assessed using the hemoSTATUS2 test; platelet count and volume also measured.

Main Results:

  • Platelet count and volume remained stable throughout labor and the postpartum period.
  • Platelet function showed significant alterations during labor, particularly in the second stage (p < 0.05).
  • Platelet function remained elevated 24 hours postpartum compared to non-pregnant controls.

Conclusions:

  • Labor is associated with significant changes in platelet function, independent of platelet count or volume.
  • Elevated platelet function persists postpartum, suggesting a potential role in postpartum hemostasis or complications.
