Medication used by Paramedics ,
Everyone knows epinephrine, Normal Saline Narcan but what about drugs that are not familiar that we use in your care.
Lets start
Ancef
Cefazolin is a cephalosporin antibiotic used by EMS to prevent and treat bacterial infections, particularly in open fractures and severe wounds.
Purpose and Indications
In the EMS setting, cefazolin is primarily used for prophylaxis against infection in patients with open fractures, deep puncture wounds, or heavily contaminated injuries where hospital arrival may be delayed by more than an hour
Its early administration significantly reduces the risk of fracture-related infections, such as osteomyelitis, and improves patient outcomes. EMS protocols also include its use in traumatic amputations or severe extremity injuries
Mechanism of Action
Cefazolin works by inhibiting bacterial cell wall synthesis, leading to bacterial death. It is effective against a broad range of gram-positive and some gram-negative bacteria.
Second
Magnesium
Why Magnesium Is Given
Magnesium is the fourth most abundant mineral in the human body and is involved in over 300 biochemical reactions, including energy production, nerve and muscle function, protein synthesis, and blood pressure regulation

, it is often given intravenously (IV) as magnesium sulfate to achieve rapid therapeutic effects when oral supplementation is too slow or ineffective.
Key Reasons for Administration
1. Severe Magnesium Deficiency (Hypomagnesemia)
Low magnesium levels can cause muscle cramps, weakness, tremors, seizures, and abnormal heart rhythms. IV magnesium quickly restores levels, especially in severe cases where oral intake is insufficient
2. Preeclampsia and Eclampsia in Pregnancy
Magnesium sulfate is the standard treatment to prevent and control seizures in pregnant women with severe preeclampsia. It reduces neuronal excitability, lowers blood pressure, and protects the fetus
3. Severe Asthma Exacerbations
In life-threatening asthma attacks unresponsive to standard bronchodilators, IV magnesium relaxes bronchial muscles, improves airflow, and can reduce the need for other medications
4. Certain Cardiac Arrhythmias
Magnesium helps stabilize heart rhythm, especially Torsades de Pointes, a dangerous rhythm often linked to prolonged QT intervals. It can suppress arrhythmias even when magnesium levels are normal
5. Acute Migraine with Aura
IV magnesium may be used in severe migraines with aura to influence brain signals and blood vessel tone, potentially reducing symptoms
TXA
Tranexamic acid (TXA) is a medication that helps prevent or reduce excessive bleeding by promoting blood clot stability.
What TXA Is and How It Works
Tranexamic acid is an antifibrinolytic agent, meaning it prevents the breakdown of blood clots. It is a synthetic analog of the amino acid lysine and works by binding to plasminogen, reducing its conversion to plasmin, which normally breaks down fibrin in clots. This helps maintain the structural integrity of clots and reduces bleeding in various medical situations
Common Uses
TXA is used to treat or prevent excessive bleeding in multiple contexts:
Heavy menstrual bleeding in women
Nosebleeds and bleeding after dental procedures.
Postpartum hemorrhage, often alongside oxytocin
Hereditary angioedema, to reduce swelling episodes
Major trauma or brain injury, where early administration can reduce mortality
These new drugs are now helping us advance your care even before you arrive at the Emergency Room.
Paramedics receive extra training thru the service Medical Director
to ensure al Paramedics are knowledgeable and capable of administering these new life saving drugs.
Some also may be hearing as of late that Paramedics can now administer whole blood, again another additive in our bag but this is one is expensive and services must weigh the cost of implementing this product verses using drugs such as TXA that can clot blood but not replace it. We must choose the benefits of same but unfortunately cost like anything else in healthcare is the driving factor for small local services. We hope as providers cost can be contained so all services can afford to implement the whole blood service but we still have advanced medication that can help compared just over a year ago when it was not available.
Each day we add to our list of medications as well as procedures that can help save lives .
