A study was designed to examine the effects of intraventricularly (i.vt.) administered morphine, apomorphine and epinephrine on the small intestine. Adult cats of either sex were implanted chronically with extracellular, monopolar electrodes at equal intervals along the entire small intestine. A collison cannula was placed in the left lateral cerebral ventricle in each animal. In animals that did not respond with emesis, morphine sulfate (200 micron g) administered i.vt. increased the incidence of spike potentials over the proximal three-quarters of the small intestine almost immediately. The response to i.vt. morphine was abolished by pretreatment with i.vt. naloxone HC1 (200 micron g) and was not obtained after peripheral (i.p.) injection of morphine at the same dose effective centrall. Now change in the number of spike potentials occure after i.vt. administration of two other potent emetic agents, apomorphine HC1 (200 micron g) and epinephrine HC1 (15O micron g), in animals that did not respond with emesis. The results suggest that the increased incidence of spike potentials after i.vt. morphine is a naloxone-sensitive, centrally mediated event not associated with activation of the central emetic mechanism.

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.
