Measure
0.9% Sodium Chloride 2000 mL Bolus
0.9% Sodium Chloride 2000 mL bolus - An intravenous line (IV) will be placed and a 1000cc bag of normal saline will be hung. If IV placement is difficult, fluid can be given through an intraosseous line. This procedure will continue until either 2 hours after hospital arrival or until control of hemorrhage is achieved whichever occurs first. 0.9% Sodium Chloride 2000 mL bolus: The systolic blood pressure (SBP) is 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. Once the total fluid reaches 2 liters and the SBP exceeds 110 mmHg, the fluid will be stopped and restarted as necessary to maintain a goal SBP of 110 mmHg.
0.9% Sodium Chloride 250 mL Bolus
0.9% Sodium Chloride 250 mL bolus - A large bore IV will be placed and a 250cc bag of normal saline (NS) will be hung. If IV placement is difficult, NS can be given through an intraosseous line. The procedure will continue until 2 hours after arrival to the hospital or until hemorrhage control is achieved whichever occurs first. 0.9% Sodium Chloride 250 mL bolus: Either systolic blood pressure (SBP) or radial pulse is the endpoint for fluid resuscitation to patients randomized to the experimental group. Patients receive 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 is given only to keep the vein open. 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.

Outcome measures

Outcome measures
Measure
Standard Resuscitation (SR)
n=33 Participants
Patients in the SR group received 2 liters of fluid as an initial bolus. Following the initial bolus, additional fluid was given a needed to maintain a SBP of 110 mmHg for the duration of the study period.
Controlled Resuscitation (CR)
n=32 Participants
Patients in the CR group received a 250 milliliter (ml) bolus of saline only if their SBP was \< 70 millimeters of mercury (mmHg) or they had no palpable radial pulse.
ECV Difference [Standard - Controlled]
ECV treatment difference between SR and CR
Penetrating Trauma 24 Hour Mortality
Alive at 24 hours after hospital arrival
30 participants
29 participants
Penetrating Trauma 24 Hour Mortality

Measure
Standard Resuscitation (SR)
n=95 participants at risk
Patients in the SR group received 2 liters of fluid as an initial bolus. Following the initial bolus, additional fluid was given a needed to maintain a SBP of 110 mmHg for the duration of the study period.
Controlled Resuscitation (CR)
n=96 participants at risk
Patients in the CR group received a 250 milliliter (ml) bolus of saline only if their SBP was \< 70 millimeters of mercury (mmHg) or they had no palpable radial pulse. The total number of patients at risk is one less than the total number of patients enrolled. Regulatory restrictions for prisoners required that no data collection, including severe adverse events, be performed for the patient who was determined to have been in police custody at the time of enrollment.
