Between 1981 and 1985 we carried out a study in two medium-sized nonteaching community hospitals to determine the rate of deterioration of knowledge and skills in cardiopulmonary resuscitation (CPR) among physicians and nurses, the accuracy of their perceptions of their knowledge and skills, the effects of practice on retention and the effect of CPR training on mortality. The participants' knowledge and skills were measured before training and immediately after, 6 months after and 12 months after training. Information on all attempts at CPR involving hospital staff was collected from medical records and from interviews with the participants. ⋯ Experience with CPR did not contribute to post-training knowledge or skills in either group. There was no evidence that death rates were lower when basic life support (BLS) was begun by trained staff than when it was begun by untrained staff. The probability of survival was greater when BLS was begun within 4 minutes of arrest than when it was begun after 4 minutes, regardless of whether advanced cardiac life support was begun within 10 minutes.

We describe the development and operation of an emergency support service team in the Emergency Department of the Kingston General Hospital, Kingston, Ont. The team, composed of professionals from other departments of the hospital, provides emotional and practical support to family members or survivors in medical emergencies. We discuss the roles of the team members and their procedures for dealing with distress and grief.

Beta-blocker therapy is associated with an increase in the severity and, possibly, the incidence of acute anaphylaxis. The population at risk consists of people with allergic conditions who are given a beta-blocker for an unrelated condition. Anaphylaxis under these conditions may be severe, protracted and resistant to conventional treatment because of the beta-adrenergic blockade. ⋯ Clinical allergists, internists and family practitioners in particular should be aware of the need for aggressive and prolonged support in patients who experience anaphylaxis while receiving beta-blocker therapy and should report all such occurrences to the federal registry of adverse drug reactions. Allergy skin testing or immunotherapy is inadvisable in patients who take a beta-blocker orally or in the form of ophthalmic eyedrops. The list of relative contraindications to beta-blocker use should be extended to include susceptibility to recurrent anaphylaxis, whether it is idiopathic or due to an identifiable cause.
