Subjective discomfort caused by nausea and hot, pruritic skin has been described in patients after ingestion of therapeutic dosages of niacin is shown by this study to be alleviated by propranolol HC1. A dosage of 2 mg, I.V., given incrementally, in a clinical trial of six patients is described. The peripheral vasodilator effects of niacin were attenuated in some subjects but not in others. However, all subjects reported relief of unpleasant symptoms. Serial vital signs were taken and no significant changes were found. It is postulated that propranolol HC1 exerts a calmative effect at the CNS level. In a series that utilized doses of 40 and 80 mg of propranolol HC1 taken orally 30 min prior to the ingestion of 500 or 1000 mg of niacin, a progressive increase in the onset of the niacin flush was observed. It is proposed that as the available plasma level of propranolol HC1 falls, the ratio of niacin to propranolol HC1 increases, exceeding the threshold at which the flush occurs. Both these studies suggest that further work is indicated to establish the possible therapeutic efficacy of propranolol HC1.

Nursing management of second trimester abortion by PGE2 suppository after cervical dilatation with laminaria or Lamicel focuses on monitoring and treating side effects, managing pain, and supporting the patient emotionally. Mean abortion time by this method is 15-17 hours, within 24 hours in 80% of women. The side effects expected from PGs are nausea, vomiting, abdominal cramps, and diarrhea. Premedication with transdermal scopolamine, and ancillary methods such as giving ice chips, airing the room, keeping the patient clean are helpful. Acetaminophen is given orally or rectally for fever, headache, or chills. A beta-adrenergic tocolytic drug such as ritodrine HC1 is given if uterine contractions become tetanic, contractions 2-3 per minute or lasting longer than 6-90 seconds, detected by palpation. This drug must be used with caution in patients with asthma. Pain management in midtrimester abortion depends solely on the woman's comfort. Meperidine, morphine, epidural anesthesia with bupivacaine, lidocaine or morphine SO4, or patient-controlled anesthesia may be used. The nurse should monitor side effects such as hypotension, allergic responses, arrhythmias, and inability to void. Midtrimester abortion is often a stress-filled experience, since women may be ambivalent upon learning of fetal abnormalities. The women should be monitored after delivery to ensure that her uterus remains contracted, and assisted if surgical removal of retained products is necessary. Patients teaching for discharge, including medication to prevent lactation, is described. A care plan is suggested for assisting the family with bereavement, based on that used in case of stillbirth or neonatal deaths.
