Resuscitation
-
The use of emergency cardiopulmonary bypass (ECPB) resuscitation after cardiac arrest may offer hope for survival when standard ACLS therapies fail. However, whether cooling adds benefit to ECPB is unknown and we lack an ECPB rodent model for experimental studies. We sought to (a) develop a 72 h survival rodent model using ECPB to treat asphyxial cardiac arrest and (b) use this new model to evaluate early mild and moderate hypothermia versus normothermia during ECPB resuscitation. ⋯ A rodent model of ECPB is feasible and useful for resuscitation studies. The addition of early mild and moderate hypothermia to ECPB resuscitation significantly improves survival compared with normothermic ECPB in rats.

Comparative Study
A comparison of the I-gel supraglottic airway as a conduit for tracheal intubation with the intubating laryngeal mask airway: a manikin study.
Insertion of a supraglottic airway and tracheal intubation through it may be indicated in resuscitation scenarios where conventional laryngoscopy fails. Various supraglottic devices have been used as conduits for tracheal intubation, including the intubating laryngeal mask airway (ILMA), the Ctrach laryngeal mask and the I-gel supraglottic airway. ⋯ The results of this study show that, in manikins, fibreoptic intubation through both ILMA and I-gel is a highly successful technique. Blind intubation through the I-gel showed a low success rate and should not be attempted.

Comparative Study
Comparison of intravenous and intraosseous access by pre-hospital medical emergency personnel with and without CBRN protective equipment.
Rapid intravascular access is a prerequisite component of emergency care and resuscitation. Peripheral intravenous (IV) access is the first-choice for most of the medical or trauma patients, but may be delayed in emergency conditions because of various difficulties. Elsewhere, intraosseous (IO) access may now be easily performed with a new semi-automatic battery-powered IO-insertion device (EZ-IO. The aim of this study was to compare the overall time to establish IO infusion with the EZ-IO device and the equivalent time for peripheral IV infusion, performed by emergency personnel in standard (No-CBRN) and in chemical, biological, radiological, and nuclear (CBRN) protective equipment. ⋯ The time to establish IO infusion was significantly shorter than that for peripheral IV infusion, under both No-CBRN and CBRN conditions. Further clinical studies are required to confirm that IO access would effectively save time over IV access in real pre-hospital emergency settings.
