Summary
This study details how to extract extra epinephrine doses from a single-use Symjepi prefilled syringe. This technique can be crucial for managing anaphylaxis in resource-limited environments.
Area of Science:
- Emergency Medicine
- Pharmacology
- Medical Device Engineering
Background:
- Anaphylaxis requires immediate epinephrine treatment.
- Epinephrine autoinjectors offer standardized dosing but are single-use.
- Austere settings necessitate maximizing available medication.
Purpose of the Study:
- To provide instructions for obtaining additional epinephrine doses from a Symjepi prefilled syringe.
- To address the limitation of single-use epinephrine devices in critical situations.
Main Methods:
- Deconstruction of the Symjepi prefilled syringe.
- Demonstration of dose extraction through videography.
- Step-by-step procedural outlining.
Main Results:
- Successful extraction of additional epinephrine doses from the Symjepi syringe is demonstrated.
- The procedure is detailed to allow for replication.
Conclusions:
- The Symjepi prefilled syringe can be deconstructed to yield extra epinephrine doses.
- This method offers a potential solution for extended anaphylaxis management in austere environments.

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...
