Section 01
By the end of this course, the learner should be able to:
Section 02
Review the supplied Massachusetts Protocol 4.5 reference.

Section 03
Treat exsanguinating hemorrhage before the traditional ABC sequence.
Section 04
Control life-threatening bleeding immediately.
Section 05
A pelvic fracture may conceal major internal hemorrhage.
Use a commercial pelvic stabilization device when available and appropriate. A bed sheet may be used if necessary.
Section 06
Establish access while transport is underway.
Initiate one or two large-bore IVs with normal saline at KVO while en route to the hospital.
Section 07
Balance airway intervention against oxygenation, ventilation, and transport time.
Patients requiring emergent intubation who cannot be intubated conventionally should be managed under Protocol 5.2 Difficult Airway.
The airway is usually best managed with BVM or SGA. Intubation may be preferred in selected cases at the treating paramedic’s discretion.
Section 08
Use the adult-style pathway in the supplied protocol.
Section 09
Use weight-based dosing and slower administration.
Dose Example
20 kg × 15 mg/kg = 300 mg TXA
Section 10
Timing, allergy, rate, and dose matter.
Caution
Do not administer when more than 3 hours have passed since the traumatic event or delivery, or when the patient has a known TXA allergy.
Caution
Administration that is too rapid may cause profound hypotension. Excessive dosing may cause seizures.
Section 11
Definitive hemorrhage control usually occurs at the trauma center.
Section 12
Pause before opening each discussion.
Direct pressure fails to control severe lower-leg bleeding.
A struck pedestrian has pelvic pain, instability, and hypotension.
An adult has HR 126, SBP 94, abdominal tenderness, and concern for internal hemorrhage.
A 4-year-old weighing 18 kg meets protocol criteria.
The patient presents 4 hours after injury.
Section 13
Document timing, interventions, and response.
