Example 6: (continued)
successfully, so that pressure is at or below allowable limits.
The prospective donor taking antihypertensives should be
free from side effects of the drug, especially episodes of
postural hypotension, and should be free of any
cardiovascular symptoms. Asymptomatic patients taking
methyldopa (Aldomet) may have a positive, direct
antiglobulin test in which case their blood should not be
used for transfusion.
4 Isoniazid given because the tuberculin skin test has
converted but without evidence of tuberculosis.
5 Over-the-counter bronchodilators and decongestants.
6 Oral hypoglycemic agents in well-controlled diabetics without
any vascular complications of the disease.
7 Tranquilizers, under most conditions. A physician should
evaluate the donor to distinguish between tranquilizers and
anti-psychotic medications. Donors taking anti-psychotic
agents should be deferred because their mental processes
might be sufficiently disordered that it would be difficult to
obtain a good, complete medical history from them.
8 Hypnotics used at bedtime, or regularly at bedtime.
