Methemoglobin levels following sublingual nitroglycerin in human volunteers.

Sublingual nitroglycerin 0.8 mg every five minutes for a total of 4.8 mg was administered to 11 healthy volunteers. One volunteer had to withdraw due to a hypotensive bradycardic reaction after 2.4 mg. In the remaining subjects, methemoglobinemia over the next hour never significantly increased from baseline levels, reaching a peak of only 0.71%. We conclude that commonly used doses of sublingual nitroglycerin do not induce significant methemoglobinemia and that nitroglycerin would not be useful in the treatment of cyanide poisoning.

The incidence of myoglobinuria in patients with pneumatic trousers.

The possible association between the use of pneumatic trousers and myoglobinuria was investigated. One hundred and four victims of multiple trauma were entered into a study over a three-month period. Patients who suffered serious injuries to two or more organ systems qualified for entrance into the study. Patients who arrived at the emergency department with inflated pneumatic trousers served as the test population (n = 50), and patients who did not have pneumatic trousers served as the controls (n = 54). Urine specimens were obtained from all patients just before the completion of their treatment in the emergency department. No patients in the control group had myoglobinuria 0%), and only one patient in the test group had myoglobinuria 2%). The results were not statistically significant. Myoglobinuria is not an acute complication of the use of pneumatic trousers. The presence of pneumatic trousers on a multiple-trauma patient is not an indication for routine screening for myoglobinuria in the emergency department.

Acceptance of the physician assistant by nonphysician health professionals in the Indian Health Service.

A survey of 55 licensed practical nurses, registered nurses and pharmacists in the Indian Health Service was conducted to determine attitudes about the use of physician assistants (PAs). The results tend to support findings of similar studies reported in the literature, but performed in other settings. Overall the PAs appear to have gained general acceptance among nonphysician health professionals. There are significant differences between the responses of LPNs and RNs, with the latter perceiving more conflict with PAs and being less supportive of the emergence of the role. Separation of the responses of LPNs and RNs, at least in this setting, appears to be an important distinction in the analysis and understanding of staff acceptance. Pharmacists were generally approving of the skill levels the PAs demonstrated in areas related to pharmacy, and tended to be intermediate in their response rates relative to LPNs and RNs in overall acceptance of the PA role.

Emerging public health issues in Alaska: occupational and environmental health.

The principal purpose of this article is to examine selected Alaskan occupational and environmental health problems and associated issues. Specifically, we focus on two traditional areas of interest in occupational and environmental health: 1) Job-related injuries, illnesses, and fatalities, and 2) accidental spills and uncontrolled waste sites involving hazardous materials. In 1986 the Alaska Department of Labor reported 13,154 recordable occupational injuries and illnesses among workers in the private sector. The injury rate for private sector workers was 10.2 cases per 100, compared to a rate of 7.9 for the U.S. private sector as a whole. There are approximately 550 known hazardous waste sites in Alaska identified by military, other federal, or state sources. One study documents 1,330 hazardous materials incidents in Alaska during a one year period. Effective public health policy for these occupational and environmental health hazards requires the development of an adequate database and a specific plan of action for the future.

Scholarship support for Indian students in the health sciences: an alternative method to address shortages in the underserved area.

The University of New Mexico Area Health Education Center was established in conjunction with the Navajo Health Authority to begin health manpower development immediately in the Navajo Nation and surrounding areas (a territory approximately the size of West Virginia). To this end, a student support program was established at the Navajo Health Agency to recruit and support Indian students with scholarships, to provide them with culturally based counseling, and to reinforce the students' intentions of ultimately returning to serve Indian people. No payback penalties or other forms of coercion were used in this program to encourage students to return to the underserved Indian areas.From October 1973 through September 1977, 124 students graduated with 125 degrees or certificates in all aspects of health care. Of these 124 students, 76 were employed. The remaining were continuing their education, unemployed, untraceable, or deceased. Of the 76 employed, 61 were from tribes within the Navajo Nation; of these 61, 56 returned to their area to serve Indians. This return rate to an underserved area is substantially better than anticipated from a review of programs that employ a variety of coercive methods to encourage recipients of loans to settle in specific underserved areas after the necessary training.
