What is the recommended dose of adrenaline in a cardiac arrest patient?

The recommended dose of adrenaline in a cardiac arrest patient is 1 mg (1:10,000) administered intravenously (IV) or intraosseously (IO) every 3 to 5 minutes during resuscitation efforts. This dosage is aligned with current resuscitation guidelines, which emphasize the importance of using the correct concentration and timing of adrenaline to optimize the chances of return of spontaneous circulation (ROSC).

Adrenaline plays a crucial role in cardiac arrest management as it helps to enhance coronary and cerebral perfusion pressures during cardiopulmonary resuscitation (CPR). By administering it at the specified intervals, resuscitation teams can ensure that the circulation is adequately supported while also providing sufficient time to evaluate the patient's response to the resuscitation efforts.

The timing of every 3 to 5 minutes strikes a balance between maintaining vascular tone and avoiding potential negative effects that could arise from more frequent dosing. The specific concentration of 1:10,000 ensures that the amount of adrenaline is effective while being safe for the patient. These guidelines are based on extensive research and consensus among resuscitation experts to maximize survival rates in out-of-hospital and in-hospital cardiac arrests.
