Summary

Minimizing fluid resuscitation in traumatic shock is crucial. Early fluid administration can worsen bleeding and dilute clotting factors, potentially reducing survival rates until bleeding is controlled.

Area of Science:

  • Trauma and Emergency Medicine
  • Surgical Research
  • Hemorrhagic Shock Pathophysiology

Background:

  • Fluid resuscitation is standard for hemorrhagic shock, but models often lack uncontrolled bleeding.
  • Clinical hemorrhage differs significantly from controlled experimental models.

Purpose of the Study:

  • To investigate the impact of early fluid resuscitation on outcomes in uncontrolled hemorrhage.
  • To compare the effects of lactated Ringer's and hetastarch on bleeding and coagulation.

Main Methods:

  • Rats underwent controlled transection of the ileocolic artery and vein for free bleeding.
  • Animals were randomized to no resuscitation, small/large volume lactated Ringer's, or small/large volume hetastarch.
  • Outcomes measured included peritoneal blood volume, hematocrit, platelet count, fibrinogen, and survival.

Main Results:

  • Fluid resuscitation (lactated Ringer's or hetastarch) increased peritoneal bleeding and diluted clotting factors compared to no resuscitation (P < 0.05).
  • Unresuscitated animals exhibited the highest survival rates.
  • Small volume hetastarch group showed significantly lower survival than the no resuscitation group (P < 0.05).

Conclusions:

  • Minimizing fluid resuscitation in uncontrolled traumatic shock is recommended until bleeding is mechanically controlled.
  • Early fluid administration may exacerbate hemorrhage and impair coagulation, negatively impacting survival.
