Comparative Study
Quality of bystander cardiopulmonary resuscitation influences outcome after prehospital cardiac arrest.
To evaluate the influence of quality of bystander cardiopulmonary resuscitation (CPR) on outcome in prehospital cardiac arrest we consecutively included patients with prehospital cardiac arrest treated by paramedics in a community run ambulance system in Oslo, Norway from 1985 to 1989. Good CPR was defined as palpable carotid or femoral pulse and intermittent chest expansion with inflation attempts. Outcome measure was hospital discharge rate. ⋯ There were no differences in paramedic response interval between the groups, but the mean interval from start of unconsciousness to initiation of CPR (arrest-CPR interval) was significantly shorter in the group receiving good bystander CPR (2.5 min, 95% confidence interval (CI): 1.7-3.3 min) than no good CPR (6.6 min, CI: 5.2-8.0 min) or no bystander CPR (7.8 min, CI: 7.2-8.4 min). Bystanders started CPR more frequently in public than in the patient's home (58 vs. 34%, P < 0.0005). Good bystander CPR was associated with a shorter arrest-CPR interval and improved hospital discharge rate as compared to no good BCPR or no BCPR.

Between 1983 and 1989, 962 patients in Rotterdam were resuscitated outside hospital, of whom 240 (25%) could be discharged alive. A follow-up study was performed to determine prognosis in these patients. Of the 240 survivors of out-of-hospital resuscitation 80% survived after 1 year and 61% after 5 years. ⋯ Multivariate analysis revealed that this difference could be explained by a larger proportion of patients with a primary arrhythmia in the latter group. Since long-term prognosis after out-of-hospital resuscitation is satisfactory, programmes for resuscitation courses should be stimulated. Such programmes should aim predominantly at relatives of patients with known heart disease, police officers and children.

The reluctance of house staff to perform mouth-to-mouth resuscitation in the inpatient setting: what are the considerations?
Medical house staff are required to perform cardiopulmonary resuscitation (CPR) as part of their job responsibilities. Previously it has been shown that house staff are reluctant to perform mouth-to-mouth resuscitation (MMR) in an out of hospital setting. Therefore, whether reluctance to perform MMR extends to the inpatient setting, and, if so, the reasons for this reluctance were investigated. ⋯ Medical housestaff are quite reluctant to perform MMR in an inpatient setting. Thus, educating the medical house staff about the percent of patients that survive inpatient cardiac arrest and the actual risks of contracting infectious diseases, especially HIV infections, from MMR and preventative measures, such as effective barrier masks, should result in an increased willingness of physicians to perform MMR or mouth-to-mask ventilation on inpatients.

We describe and evaluate a pilot course designed to teach rapid sequence intubation (RSI) to pediatric emergency physicians. A questionnaire was utilized to assess participants' self-assessment of knowledge and skills in defined areas related to rapid sequence intubation, before and after the course. Thirteen pediatric emergency physicians (nine attendings and four fellows) participated in the pilot course. ⋯ These areas included: knowledge of indications and contraindications for RSI, knowledge of specific sedating and paralyzing agents, knowledge of complications of RSI and their management, and level of comfort performing RSI when indicated (P < 0.05). We conclude that a formal course can significantly enhance self-assessment concerning ability to perform rapid sequence intubation. Further study is required to determine if such a course improves performance of this procedure.

The administration of ATP-MgCl2 may be of benefit in the treatment of shock by improving cellular metabolic function during resuscitation. Prior studies have reported data from hemorrhage models in which heparinized shed blood is returned both during shock and in resuscitation. The purpose of this study was to test the effects of ATP-MgCl2 therapy upon blood pressure and survival in an animal model of hemorrhagic shock utilizing crystalloid (Lactated Ringer's) resuscitation. ⋯ Blood pressure was monitored throughout the procedure and survival time was noted. Post-resuscitation MAP was increased in animals treated with ATP-MgCl2. ATP-MgCl2 added to resuscitation significantly improved 72-h survival over that of control (LR) animals, and animals treated with MgCl2 alone.
