Comparative Study
Predictive factors for positive coronary angiography in out-of-hospital cardiac arrest patients.
Coronary angiography is often performed in survivors of out-of-hospital cardiac arrest, but little is known about the factors predictive of a positive coronary angiography. Our aim was to determine these factors. ⋯ Among the factors identified, diabetes and a history of coronary artery were strong predictors for a positive coronary angiography, whereas ST segment elevation was not as predictive as expected.

Randomized Controlled Trial Comparative Study
Comparison of GlideScope video laryngoscope and intubating laryngeal mask airway with direct laryngoscopy for endotracheal intubation.
The aim of this study was to determine whether GlideScope video laryngoscope (GVL) and intubating laryngeal mask airway (i-LMA) improve the intubation success rate and could be easily learned and performed by paramedic students when compared with the direct laryngoscopic (DL) method. The study was designed as a prospective randomized crossover trial that included 121 paramedic students. All participants were asked to intubate each Ambu Airway Management Trainer manikins after the lecture and demonstration. ⋯ Success rates of i-LMA and GVL were significantly higher compared with DL (P=0.005 and P=0.006, respectively). No significant difference was determined between i-LMA and GVL in terms of successful intubation (P>0.05). This study showed that GVL and i-LMA provided better intubation success rates and were easier for paramedic students when compared with the classic DL method.

Comparative Study
Physician experience in addition to ACLS training does not significantly affect the outcome of prehospital cardiac arrest.
Little data exists on whether the physicians' skills in responding to cardiac arrest are fully developed after the advanced cardiac life support (ACLS) course, or if there is a significant improvement in their performance after an initial learning curve. ⋯ In this study, resuscitative experience of the physician did not have a significant effect on survival suggesting that experience does not significantly add to the current ACLS training in responding to ventricular fibrillation/ventricular tachycardia. More studies are needed.

Comparative Study
The utility of shock index in differentiating major from minor injury.
The importance of early recognition of hemorrhagic shock and its effects on outcome have long been recognized. Traditional vital signs are relatively insensitive as early diagnostic markers of hemorrhage. The shock index (SI); heart rate (HR) divided by systolic blood pressure (SBP), has been suggested as such a marker. We tested the diagnostic utility of the SI in differentiating major from minor injury in trauma patients. ⋯ The SI can be a valuable tool, raising suspicion when it is abnormal even when other parameters are not, but is far too insensitive for use as a screening device to rule out disease. A normal SI should not lower the suspicion of major injury.

Comparative Study
Therapeutic hypothermia after cardiac arrest in Lower Austria--a cross-sectional survey.
This study was undertaken to evaluate the use of therapeutic hypothermia (TH) after cardiac arrest in Lower Austria. A questionnaire was sent to intensive care units (ICUs) in Lower Austria. Methods of inducing and maintaining hypothermia, the practise of rewarming, concomitant therapies and reasons not to cool were documented. ⋯ Reasons not to cool were insufficient staff resources (n=4, 17%), technical complexity of cooling (n=4, 17%) and too little information (n=3, 13%). In conclusion, TH has been poorly implemented in Lower Austria. The reasons for not using hypothermia could possibly be dispelled by education.
