Final answer:
The recommended dose of IV/IO epinephrine for adults is 1 mg (1:10,000 solution) every 3-5 minutes during cardiac arrest, and doses for anaphylactic shock vary with severity, often starting at 0.3 to 0.5 mg intramuscularly. Pediatric dosing is typically 0.01 mg/kg for cardiac arrest. Auto-injectors like EpiPens contain fixed doses for emergency situations.
Step-by-step explanation:
The recommended dose of intravenous (IV) or intraosseous (IO) epinephrine is not expressed in mL/kg for adults, but rather in standard doses.
For an adult experiencing cardiac arrest, the Advanced Cardiac Life Support (ACLS) guidelines recommend a dose of 1 mg of epinephrine 1:10,000 every 3 to 5 minutes during resuscitation efforts. For anaphylactic shock, the initial doses can vary depending on the protocol, but often a 0.3 to 0.5 mg dose of 1:1,000 epinephrine is administered intramuscularly with the IV/IO route and dosages determined by clinical judgement based on the severity of the reaction.
Paediatric doses for cardiac arrest are typically 0.01 mg/kg of the 1:10,000 solution. These doses are different from those found in auto-injectors like EpiPens®, which contain a premeasured amount of epinephrine, typically 0.3 mg for adults and 0.15 mg for children.
