Increased pulmonary arterial pressures after pentazocine in myocardial infarction.

In 15 patients with acute myocardial infarction intravenous pentazocine in a dose of either 30 or 60 mg. was followed by a significant increase in mean pulmonary arterial pressure. In the group receiving the 60-mg. dose this change was associated with a significant increase in systemic arterial pressure, total peripheral resistance, and left ventricular minute work. Because of these circulatory effects intravenous pentazocine in a dose of 60 mg. would seem to be unsuitable for the relief of pain in myocardial infarction.

Which disposable chest electrode?

Chest electrodes are preferred to limb electrodes for cardiac monitoring, as limb movements are not restricted and produce less interference of the E.C.G. trace. Eight types of disposable chest electrodes were investigated to compare their performance, skin reactions, cost, ease of application, size, and skin-electrode impedance.Elema-Schonander electrodes were found to be the most efficient and the most expensive. In their application care was required to avoid severe skin reactions.Dracard electrodes were simple to attach, worked well without severe skin reactions, and were cheap. They are recommended for routine use. Smith and Nephew electrodes, a type of "multipoint electrodes" which do not require electrode jelly, frequently produced severe skin reactions, making them unsuitable for monitoring for periods exceeding 12 hours.

Value of routine cardiac monitoring in the management of acute myocardial infarction outside a coronary care unit.

In a coronary care unit patients and electrocardiographic monitors are under almost continuous observation by trained personnel. This paper suggests that in a general medical ward without this facility routine cardiac monitoring with E.C.G. oscilloscopes is unlikely to lower the overall mortality from acute myocardial infarction. A mortality of 25% for acute myocardial infarction was the same for a hospital without a coronary care unit where monitoring was routinely performed and for two neighbouring hospitals which did not routinely use monitoring during the period of analysis.The need to train personnel in the recognition of E.C.G. monitor tracings and the difficulties associated with monitor alarm systems are emphasized.
