Although both vasopressors, vasopressin and epinephrine differ in that vasopressin does not have direct effects on cardiac contractility as epinephrine does. [18] Thus, vasopressin is theorized to be of increased benefit over epinephrine in cardiac arrest due to its properties of not increasing myocardial and cerebral oxygen demands. [18]
Cardiac arrest, also known as sudden cardiac arrest (SCA), [11] is when the heart suddenly and unexpectedly stops beating. [12][1] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased. When the brain does not receive enough blood, this can cause a person to ...
Vasopressin. Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, [5] is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, [6] and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles ...
Vasopressin comes as the second-line agent. [24] However, high-dose therapy is linked to excessive coronary, splanchnic vasoconstriction, and hypercoagulation. [6] Excessive vasoconstriction can cause cardiac output reduction or even fatal heart complication particularly in those with weak myocardial function. [6] [4] [28] [29]
Traumatic cardiac arrest (TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care. Even with prompt medical intervention, survival without neurological ...
Pulseless electrical activity. Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests. [2]
Extracorporeal cardiopulmonary resuscitation. Extracorporeal cardiopulmonary resuscitation (commonly known as ECPR) is a method of cardiopulmonary resuscitation (CPR) that passes the patient's blood through a machine in a process to oxygenate the blood supply. A portable extracorporeal membrane oxygenation (ECMO) device is used as an adjunct to ...
Advanced cardiac life support refers to a set of guidelines used by medical providers to treat life-threatening cardiovascular conditions. These life-threatening conditions range from dangerous arrhythmias to cardiac arrest. ACLS algorithms frequently address at least five different aspects of peri-cardiac arrest care: Airway management ...
