Randomized Controlled Trial Clinical Trial
Factors influencing Queenslanders' willingness to perform bystander cardiopulmonary resuscitation.
The chances of surviving an out-of-hospital cardiac arrest (OHCA) are greatly increased if a bystander provides cardiopulmonary resuscitation (CPR) while awaiting the arrival of the emergency medical services. Over 50% of adult Queenslanders have been trained in CPR at some time in the past, however, little is known about the factors that affect their willingness to perform CPR. ⋯ This study indicates that there is considerable variation in Queenslanders' willingness to perform bystander CPR. Public health education campaigns aimed at correcting inaccurate perceptions of risk and addressing other barriers to bystander CPR would promote its use in response to OHCA.

Emergency oral tracheal intubations in the pre-hospital setting can be more difficult because the rescuer's position with respect to a patient lying on the ground may not provide optimal conditions for intubation. Since optimal visualisation of the larynx often depends on the force generated during laryngoscopy, we measured the pressure required for intubation (P(i)) as well as the maximum pressure (P(max)) that can be generated with the laryngoscopy blade in seven intubator positions. ⋯ The straddling position affords the intubator significantly more reserve force than the prone, right lateral decubitus or sitting position. We suggest that the straddling position may be an advantageous position for pre-hospital intubations especially when visualisation of the glottis is difficult.

Carbon monoxide (CO) poisoning resulting in diffuse tissue hypoxia. Cerebral hypoxia is a major cause of morbidity and mortality after CO poisoning. There are some clinical criteria that could help a physician to make a decision concerning the application of hyperbaric oxygenation therapy. ⋯ We present two case reports where the established criteria for the CO poisoning were not optimum for the decision regarding therapy. It seems that the S-100B protein could be used as a biochemical marker of CO induced brain injury. S-100B values could perhaps help us to select patients for hyperbaric oxygen therapy and to predict the short and long term outcome.

Survival after out-of-hospital cardiac arrest (OOHCA) in an urban environment is directly proportional to speed of defibrillation and effective bystander cardiopulmonary resuscitation (CPR). We hypothesized that the hospital discharge rate from rural OOHCA was affected by the same factors. ⋯ Our data suggest improvement in response time and bystander CPR might further improve survival in a rural setting.

To measure an appropriately sized nasopharyngeal airway, it is taught that the size is related to the patients little finger or nostril (anterior nares). This study has been designed to identify whether these comparisons are valid. ⋯ The methods used traditionally to size a nasopharyngeal airway do not correlate with the airway anatomy and are unreliable. It is more appropriate to size the airway dependent upon the patient's size, sex and race.
