Multicenter Study Comparative Study
Resuscitation of out-of-hospital cardiac arrests in residential aged care facilities in Melbourne, Australia.
CPR in patients in residential aged care facilities (RACF) deserves careful consideration. We examined the characteristics, management and outcomes of out-of-hospital cardiac arrest (OHCA) in RACF patients in Melbourne, Australia. ⋯ Resuscitation of patients in RACF is not futile. However, informed decisions concerning resuscitation status should be made by patients and their families on entry to a RACF. Where it is appropriate to perform resuscitation, outcomes may be improved by the provision of BLS training and possibly AED equipment to RACF staff.

According to a directive of the European Parliament, informed consent is required to conduct a clinical trial also in emergencies when the patient is unable to provide consent. In these cases surrogate consent can be obtained from the patient's next of kin. There are no reports describing how patients and their next of kin perceive this policy. The perceptions of patients and their spouses involved in an emergency trial conducted under surrogate consent were surveyed. ⋯ Emergency research was perceived positively by cardiac arrest victims and their spouses previously involved in a resuscitation trial. Possible own participation in an emergency trial without personal consent was considered acceptable. Patients and their spouses would prefer additional research information after enrolment.

To describe the advancement of Intraosseous (IO) infusion in the spectrum of resuscitative protocols and to provide a systematic review on currently used semi-automatic IO infusion devices. The specific question addressed was: "In patients undergoing resuscitation, does the use of semi-automatic IO infusion devices compared to manual needles influence IO placement success rate, time for IO placement, and ease-of-use and user preference?" ⋯ Only a few studies compared the performance of different types of IO infusion devices, most of them have a low level of evidence. These studies suggested a superiority of the battery-powered IO driver over manual needles, and other semi-automatic IO infuson devices.

Comparative Study
Pulmonary arterial thermodilution, femoral arterial thermodilution and bioreactance cardiac output monitoring in a pediatric hemorrhagic hypovolemic shock model.
Bioreactance is a new non-invasive method for cardiac output measurement (NICOM). There are no studies that have analysed the utility of this technique in a pediatric animal model of hemorrhagic shock. ⋯ PATD and FATD measurements showed similar responses to hypovolemic shock and volume expansion. Bioreactance persistently underestimates the CI and is not significantly altered by either inducing hemorrhagic shock, or later, through volume expansion. Bioreactance is not a suitable method for monitoring the CI in pediatric hemorrhagic shock.

Comparative Study
Feasibility of initiating extracorporeal life support during mechanical chest compression CPR: a porcine pilot study.
Recently, portable extracorporeal membrane oxygenation (ECMO) machines have become commercially available. This creates the potential to utilize extracorporeal life support (ECLS) for the treatment of sudden cardiac arrest in the emergency department, and potentially in the out-of-hospital setting. ⋯ Mechanical chest compression may be a suitable therapeutic bridge to the installation of ECMO and does not interfere with ECMO catheter placement.
