Comparative Study
Effects of vasopressin on adrenal gland regional perfusion during experimental cardiopulmonary resuscitation.
Despite the important role of the adrenal gland during cardiac arrest, little is known about changes in the adrenal medullary or cortical blood flow in this setting. This study was designed to assess regional adrenal gland perfusion in the medulla and cortex during cardiopulmonary resuscitation (CPR), and after administration of adrenaline (epinephrine) versus vasopressin versus saline placebo. ⋯ Both vasopressin and adrenaline produced significantly higher medullary and cortical adrenal gland perfusion during CPR than did a saline placebo; but vasopressin resulted in significantly higher medullary adrenal gland blood flow when compared with adrenaline.

One of the objectives of this study was to assess the emergency medical dispatchers (EMDs) ability for the identification and prioritisation of cardiac arrest (CA) cases, and offering and achievements of dispatcher-assisted bystander cardiopulmonary resuscitation (CPR). The other objective was to give an account of the frequency of agonal respiration in cardiac arrest calls and the caller's descriptions of breathing. ⋯ Among suspected cardiac arrest cases, EMDs offer CPR instruction to only a small fraction of callers. A major obstacle was the presentation of agonal breathing. Patients with a combination of unconsciousness and agonal breathing should be offered dispatcher-assisted CPR instruction. This might improve survival in out-of hospital cardiac arrest.

Monitoring of end-tidal carbon dioxide (EtCO(2)) is good clinical practice in the patient who is intubated and ventilated. This study investigated the EtCO(2) values in spontaneously breathing patients treated in a physician-staffed mobile intensive care unit (MICU). This article also discusses whether EtCO(2) monitoring may have an influence on therapeutic decisions by emergency physicians by providing additional information. ⋯ Although EtCO(2) monitoring may be a useful additional variable in spontaneously breathing patients. Consideration of the respective disease and the cost to benefit ratio suggests that this method should only be used for selected indications.
