Cardiopulmonary resuscitation after near drowning and hypothermia: restoration of spontaneous circulation after vasopressin.

Recent animal data have challenged the common clinical practice to avoid vasopressor drugs during hypothermic cardiopulmonary resuscitation (CPR) when core temperature is below 30 degrees C. In this report, we describe the case of a 19-year-old-female patient with prolonged, hypothermic, out-of-hospital cardiopulmonary arrest after near drowning (core temperature, 27 degrees C) in whom cardiocirculatory arrest persisted despite 2 mg of intravenous epinephrine; but, immediate return of spontaneous circulation occurred after a single dose (40 IU) of intravenous vasopressin. The patient was subsequently admitted to a hospital with stable haemodynamics, and was successfully rewarmed with convective rewarming, but died of multiorgan failure 15 h later. To the best of our knowledge, this is the first report about the use of vasopressin during hypothermic CPR in humans. This case report adds to the growing evidence that vasopressors may be useful to restore spontaneous circulation in hypothermic cardiac arrest patients prior to rewarming, thus avoiding prolonged mechanical CPR efforts, or usage of extracorporeal circulation. It may also support previous experience that the combination of both epinephrine and vasopressin may be necessary to achieve the vasopressor response needed for restoration of spontaneous circulation, especially after asphyxial cardiac arrest or during prolonged CPR efforts.

[Lipid infusion in multiple trauma intensive care patients in the early phase of treatment]. / Fettinfusion bei polytraumatisierten Intensivpatienten in der Frühphase der Behandlung.

OBJECTIVES: To study the metabolic effects of a high-dose fat infusion application in the early phase of total parenteral nutrition (TPN) after major trauma. DESIGN: Prospective study in male patients after major trauma. SETTING: Intensive care unit of the University Clinic. PATIENTS: 21 male, mechanically ventilated patients after major trauma. INTERVENTIONS: Infusion of Elolipid 20% (Fa. Leopold, Graz, Austria), starting on the 3rd day after ICU admission (0.075 g/kg body weight/h) in 8 h. The dose was increased on the 5th day (0.125 g/kg BW/h) and on the 7th day (0.15 g/kg BW/h). RESULTS: There was a pathologic rise in serum triglycerides on days 3, 5 and 7 during the infusion period. A serious diabetic metabolic state was shown on the 3rd day. No significant changes in urea production rate could be demonstrated after the high-dose fat infusion. CONCLUSIONS: The reason for the decreased fat elimination in patients after major trauma after high-dose fat infusion (8 h) remains unclear (fat clearance or fat oxidation failure). Therefore the fat infusion should be started after normalization of the blood glucose level. Thus the fat infusion should be given continuously over 24 h to avoid serious metabolic complications.
