Efficacy of lidocaine in preventing primary ventricular fibrillation within 1 hour after a 300 mg intramuscular injection. A double-blind, randomized study of 300 hospitalized patients with acute myocardial infarction.

The effectiveness of intramuscular lidocaine in preventing in-hospital primary ventricular fibrillation within 1 hour after injection of the drug in patients with acute myocardial infarction was assessed in a double-blind randomized study performed in 300 such patients admitted within 6 hours of myocardial infarction. Six of 147 patients treated with 300 mg of intamuscular lidocaine had ventricular fibrillation compared with 4 of 153 control subjects. The lidocaine blood level of the patients who experienced ventricular fibrillation was 1.4 +/- 0.7 microgram/ml (mean +/- standard deviation) at the time of fibrillation, a value not significantly different from that of treated patients who did not experience fibrillation. Lidocaine blood levels in the latter were 1.9 +/- 1.1, 2.1 +/- 1.1, 2.1 +/- 1.1 and 1.7 +/- 0.7 microgram/ml, respectively, 7, 15, 30 and 60 minutes after injection. In this study intramuscular lidocaine was ineffective in preventing ventricular fibrillation, possibly because the given dose, 300 mg, prevented attainment of adequqte blood levels of the drug.

Follow-up research in primary prevention: a model of adjustment in acute grief.

Investigated the effects of preventive intervention that followed the life crisis of sudden death in the family. Two bereaved groups of families (one of which received preventive intervention service) and one non-bereaved group were compared in an outcome design and were assessed for indices of illness, psycho-social disturbance, and general quality of life. The results revealed that sudden death has a two-stage impact upon family survivors and that subsequent adjustment can be predicted from a knowledge of facts at the time of death. A preventive intervention service had little or no impact and may have been harmful. Discussion centered on possible intervention strategies with a focus upon the complex determinants of environmental stresses and family/individual variables.

Effect of treatment of hypertension in the primary preventive trial, Göteborg, Sweden.

1 A treatment group comprising 635 hypertensive men (casual SBP greater than 175 or DBP greater than 115 twice) was compared with a reference group (n = 391 men; casual SBP greater than 175 or DBP greater than 115 only at screening). All men belonged to the same population sample of 7,455 men aged 47-54 yr. 2 The two groups did not differ with respect to age, smoking habits or cholesterol values, but screening BPs were higher in the treatment group. 3 During 4.3 years' follow-up there was a significantly lower total death rate in the treatment group compared with reference group. 4 There was also a strong tendency towards lower incidence of non-fatal myocardial infarction (P = 0.06). The pooled incidence of non-fatal myocardial infarction and fatal CHD was lower in the treatment group than in the reference group (P less than 0.03).
