Randomized Controlled Trial Comparative Study
Comparison of ventilation and cardiac compressions using the Impact Model 730 automatic transport ventilator compared to a conventional bag valve with a facemask in a model of adult cardiopulmonary arrest.
To determine the performance of two person CPR on an instrumented manikin by registered nurses using conventional bag valve mask (BVM) ventilation or the Impact Model 730 automatic transport ventilator (Impact 730, Impact Instrumentation, Inc., West Caldwell, NJ) in CPR mode using a face mask. ⋯ Compared to the BVM, the Impact 730 is as effective, easier to use and limits the amount of gas entering the stomach when used during adult CPR in a simulated setting.

Randomized Controlled Trial Comparative Study
Medical students teaching basic life support to school children as a required element of medical education: a randomised controlled study comparing three different approaches to fifth year medical training in emergency medicine.
Basic life support (BLS) by doctors has been shown to be of poor quality. To improve medical education training should be simplified, and simultaneously the learner should be involved more actively. To combine both ideas we trained medical students to give BLS courses and sent them to teach school children. This was a requirement for their emergency medicine course. Our model was compared to conventional teaching. ⋯ Medical students teaching BLS to school children as a compulsory element of their own medical training showed superior practical skills as compared to conventional teaching. Theoretical knowledge was equivalent to the control groups, although their course contained less theoretical information.

Following the publication of the Leuven Intensive Insulin Therapy (IIT) study in 2001, tight glycemic control has become regarded as the standard of care in intensive care units throughout the world. The Leuven IIT study, was however, an unblinded, single center study with unique patient and institutional characteristics that may not extrapolate to practice elsewhere in the world. Indeed, recent randomized controlled studies have been unable to demonstrate any benefit from tight glucemic control. We suggest that the widespread adoption of tight glycemic control be abandoned at this time.

Randomized Controlled Trial
The effect on quality of chest compressions and exhaustion of a compression--ventilation ratio of 30:2 versus 15:2 during cardiopulmonary resuscitation--a randomised trial.
Recent cardio pulmonary resuscitation (CPR) guidelines changed the compression:ventilation ratio in 30:2. ⋯ Although the 30:2 ratio is rated to be more exhausting, the 30:2 technique delivers more chest compressions and the quality of chest compressions remains unchanged.

Comparative Study
Personal protection equipment for biological hazards: does it affect tracheal intubation performance?
Personal protection equipment (PPE) is recommended for use during airway management of patients with highly contagious respiratory tract illness. While its use in chemical hazards and its effect on airway management has been assessed previously, there has been no research assessing whether this equipment affects the ability to perform tracheal intubation. It is the intention of this investigation to answer this question. ⋯ Although the use of PPE may not affect the length of time to intubate manikins, certain types of PPE may be uncomfortable to wear and noisy. Further research is needed to investigate whether this could be a problem in the clinical setting or in actual difficult intubations.
