Case series: CT scan in cardiac arrest and imminent cardiogenic shock.
Imaging a patient having a cardiac arrest on the examination table is not a common occurrence. Altered hemodynamics resulting from pump failure causes stasis of blood in the dependent organs of the body, which is manifested on imaging by dependent contrast pooling and layering. ⋯ Dependent contrast pooling and layering were found in all of them, with faint or no opacification of the left cardiac chambers. Contrast pooling was noted in the dependent lumbar veins, hepatic veins, hepatic parenchyma, and the right renal vein, as well as in the dependent part of the IVC and the right heart chambers.

A 60-year-old man with history of hypertension and unspecified left ventricular dysfunction had chest pain at home at 9 am. At 1 pm he was transported to a peripheal hospital and treated for acute myocardial infarction. ⋯ At 6.30 pm the patient on extracorporeal membrane oxygenation was transferred by ambulance to the Cardiac Surgery Intensive Care Unit of San Gerardo Hospital in Monza. On day 20 he was transferred back to the original hospital without neurological deficits, with normal renal function and normal blood gas analysis.

Bystander-initiated chest compression-only CPR is better than standard CPR in out-of-hospital cardiac arrest.
Out-of-hospital cardiac arrest has a low survival rate to hospital discharge. Recent studies compared a simplified form of CPR, based on chest compression alone versus standard CPR including ventilation. We performed systematic review and meta-analysis of randomized controlled trials, focusing on survival at hospital discharge. ⋯ Available evidence strongly support the superiority of bystander compression-only CPR. Reasons for the best efficacy of chest compression-only CPR include a better willingness to start CPR by bystanders, the low quality of mouth-to-mouth ventilation and a detrimental effect of too long interruptions of chest compressions during ventilation. Based on our findings, compression-only CPR should be recommended as the preferred CPR technique performed by untrained bystander.

Resuscitation after cardiac arrest (CA) with a whole-body ischemia-reperfusion injury causes brain injury and multiple organ dysfunction (MODS). This study aimed to determine whether mild systemic hypothermia could decrease multiple organ dysfunctions after resuscitation from cardiac arrest. ⋯ In the patients who have been successfully resuscitated after cardiac arrest, therapeutic mild hypothermia can alleviate dysfunction after resuscitation from cardiac arrest.

This study was designed to evaluate the effects of terlipressin versus fluid resuscitation with normal saline, hypertonic saline or hypertonic-hyperoncotic hydroxyethyl starch, on hemodynamics, metabolics, blood loss and short-term survival in hemorrhagic shock. ⋯ Hyperkalemia accompanies hemorrhagic shock and, in addition to providing an early sign of the acute ischemic insult severity, may be responsible for cardiac arrest related to hemorrhagic shock.
