Field Trial of Hypotensive Resuscitation Versus Standard Resuscitation in Patients With Hemorrhagic Shock After Trauma: A Pilot Trial
In Brief
A Phase 2 clinical trial evaluating 0.9% Sodium Chloride 250 mL bolus and 0.9% Sodium Chloride 2000 mL bolus for Blunt Trauma and 2 related conditions. Completed, enrolled 192 participants across 6 sites in 2 countries.
Detailed Summary
Primary Aim: To determine the feasibility and safety of hypotensive resuscitation for the early treatment of patients with traumatic shock compared to standard fluid resuscitation. Primary Hypotheses: The null hypothesis regarding feasibility is that hypotensive resuscitation will result in the same volume of early crystalloid (normal saline) fluid administration compared to standard crystalloid resuscitation. The null hypothesis regarding safety is that hypotensive resuscitation will result in the same percent of patients surviving to 24 hours after 911 call received at dispatch compared to standard fluid resuscitation. Early resuscitation is defined as all fluid given until 2 hours after arrival in the Emergency Department or until hemorrhage control is achieved in the hospital, whichever occurs earlier.

Timeline
Interventions
Emergency Medicine Systems (EMS) agencies and in-hospital providers will be given the option to utilize either systolic blood pressure (SBP) or radial pulse as the endpoint for fluid resuscitation to patients randomized to the experimental group. Patients will receive a 250 ml bolus of normal saline (NS) only if the SBP is less than 70 mmHg or the radial pulse is not palpable. If the SBP is greater than or equal to 70 mmHg or the radial pulse is palpable, NS will be given to keep the vein open. The presence or absence of a radial pulse or the SBP will be documented before and after each bolus. The study will continue repeating the randomization procedure using only 250 ml bags of NS until 2 hours after arrival to the hospital or until hemorrhage control is achieved whichever occurs first.
Emergency Medicine Systems (EMS) personnel and in-hospital providers will utilize the systolic blood pressure SBP as the endpoint for delivering fluid resuscitation to patients randomized to the control group. If the SBP is equal to or less than 90 mmHg, the EMS personnel will start infusing a 1000 ml bolus of normal saline (NS) and will continue using only 1000 ml bags of NS as needed. If the total fluid resuscitation exceeds 2 liters, fluid will be stopped when the SBP exceeds 110 mmHg and restarted as necessary to maintain a goal SBP of 110 mmHg. The fluid will be given as rapidly as possible. This fluid resuscitation protocol will continue until either 2 hours after hospital arrival or until control of hemorrhage is achieved whichever occurs first.
