Adult respiratory distress syndrome precipitated by massive salicylate poisoning.

Pulmonary oedema has been reported in severe cases of acetyl salicylic acid (ASA) poisoning. Liberal use of intravenous fluids, to establish a forced diuresis, is usually thought to be the precipitating cause. A case of severe ASA poisoning and respiratory failure was found to have increased pulmonary vascular resistance and signs of intravascular hypercoagulability. The patient recovered rapidly on mechanical ventilation with a positive endexpiratory pressure of 18 cm H2O and systemic steroids.

Access to medical care in the U.S.: realized and potential.

This paper seeks to provide a framework for understanding differential access to medical care in the U.S. population and to suggest ways to achieve equity of access. The framework is provided by a behavioral model of health services utilization which suggests a sequence of predisposing, enabling and illness variables that determine the number of times people will visit a physician. The model is operationalized using a path analytic technique. The data come from a national survey of the noninstitutionalized U.S. population conducted in late 1975 and early 1976. The results suggest services are generally equitably distributed since age and level of illness are the main determinants of the number of services people receive. However, remaining inequities might be reduced by providing people who report no regular source of medical care with a familiar entry into the health service system.

Health status indices and access to medical care.

This paper examines the uses of some health status indices in measuring equity of access to medical care. Empirical examples are provided using data from national surveys of the U.S. population conducted from 1964 through 1976. A simple indicator, mean number of physician visits, suggests that between 1963 and 1976 the poor improved their position relative to the rest of the population and, indeed, currently enjoy the highest level of access. However, a second measure, the use-disability ratio indicates that the poor may still receive less care relative to their need. A third measure, the symptoms-response ratio suggests how norms of appropriate behavior might be incorporated into an access measure.

Insurance coverage and access: implications for health policy.

Data are presented from a recent survey of the United States population comparing the characteristics and levels of access to medical care of persons under 65 years who have group or individual private health insurance, public health insurance, or no third-party coverage. The uninsured group appeared to fall between the privately insured and publicly insured groups on measures of social and economic status. Persons with publicly subsidized forms of insurance coverage utilized services at the highest rates, and uninsured persons used them at the lowest rates. Neither of these groups was as satisfied with the convenience or the quality of the care it obtained as the privately insured group. Implications of these findings for national health insurance and other health policy initiatives are discussed.

Pain as a major cause of postoperative nausea.

The incidence of nausea in relation to pain was recorded in 104 patients after abdominal operations. Ten per cent of the patients had episodes of nausea not related to pain. One hundred and fourteen episodes of concomitant pain and nausea were recorded in 61 patients (58.6 per cent). The intravenous injection of morphine or ketobemidone relieved nausea as well as pain in 80 per cent of the episodes. Relief of pain with persistence of nausea was uncommon and if pain relief was inadequate nausea was unabated. Nausea was provoked by 3.4 per cent of the morphine injections, but all patients tolerated similar doses of morphine on other occasions without nausea. Nausea often accompanies pain in the early postoperative period and can be relieved concomitant with the pain by the intravenous use of opiates in adequate doses in a high proportion of cases.
