Randomized Controlled Trial Comparative Study
Effectiveness of simplified chest compression-only CPR training for the general public: a randomized controlled trial.
To compare the quality of resuscitation between those with a simplified chest compression-only cardiopulmonary resuscitation (CPR) program and those with a conventional CPR program. ⋯ A simplified chest compression-only CPR program makes it possible for the general public to perform a greater number of appropriate chest compressions than the conventional CPR program (UMIN-CTR C0000000321).

Hyperkalemia may cause cardiac pacemaker (PMK) malfunctioning due to a reduction of the electronegativity of the resting myocardial potential. Both sensing and capture mechanisms could be temporarily affected, with possible life-threatening effects. ⋯ She was managed with immediate i.v. calcium chloride, followed by insulin/glucose and sodium bicarbonate infusions; the ECG recordings show an almost immediate correction of the PMK malfunctioning and serial improvement of the intraventricular conduction. This case supports the feasibility and effectiveness of i.v. calcium administration, as expected on the basis of electrophysiological ionized calcium effect on the threshold potential.

Norwegian 7th graders (12 years old) trained CPR using a 30 min DVD, an inflatable manikin and teachers as facilitators. They were instructed to take the kit home and expose as many family members and friends (adults) as possible to the training. We wanted to document the number of lay rescuers trained by this distribution model and CPR skills achieved. ⋯ The present model of CPR kit distribution via 7th graders enabled a significant percentage of the population to focus on CPR training. We believe the model secure discipline through the training program for first tier but not for second tier and speculate that 12-year-old children are too young to have an impact of adults commitment and motivation for training.

The effect of restoring intravascular volume with polyethylene glycol (PEG) conjugated to human serum albumin (PEG-Alb) on systemic parameters and microvascular hemodynamics after hemorrhagic shock resuscitation was studied in the hamster window chamber model. Moderate hemorrhagic shock was induced by controlled arterial bleeding of 50% of blood volume, and hypovolemia was maintained for 1h. Fluid resuscitation was accomplished by infusion of 25% of blood volume and recovery was followed over 90 min. ⋯ Systemic and microvascular recovery was best and most rapid with PEG-Alb and followed by HSA10 and HSA5. Only recovery with PEG-Alb was sustained beyond 90 min. Hemodynamic functional benefits of PEG-Alb and the potential disadvantages associated with HSA, suggest PEG-Alb as better resuscitation solution.
