A great number of patients with gynaecological malignant diseases suffer from severe pain, caused, for example, by bone metastases of breast cancer or tumour infiltration of the pelvis and the lumbar plexus in uterine cancer. Several methods of treatment are available depending upon the origin of pain. It is possible to achieve pain relief by radiotherapy or by cytostatic therapy. Sometimes, anaesthesiological and neurosurgical measures are successful, but the most important method is treatment with analgesics. Strong opioids are given, if pain relief is insufficient under treatment with non-narcotic drugs or weak opioids, like codeine. Morphine and other strong opioids are not reserved for pain control only in terminally sick women, as they can be administered successfully for long periods without severe side effects. If possible, the oral route should be selected. If vomiting occurs, or if patients are unable to take oral medication, morphine can be given peridurally, intrathecally or by infusion. Often, an additional treatment is necessary with different medicaments like tricyclic antidepressants and corticosteroids.

Morphine, meperidine and ketobemidone used in continuous i.v. infusion for postoperative pain relief were compared in a double-blind, controlled, prospective study in 81 consecutive consenting adult patients after open-heart surgery, with permission from the hospital ethics committee. During the first postoperative period, the infusion rates were fixed. Later on, when the infusion rate could be regulated according to individual patient needs, the variation in infusion rate was large, in accordance with earlier studies. No significant differences were demonstrated between the three analgesics with respect to efficacy of analgesia or side effects like shivering, nausea or vomiting. Respiratory depression following extubation was not observed. During shivering, there was a significant increase in the arterio-mixed venous difference of oxygen in all groups. The amounts of opioids used were relatively small compared to amounts used in patients following abdominal surgery. When interviewed some days after surgery, 18/74 patients remembered moderate pain and 11 severe pain during the stay in the ICU.

Forty-five patients undergoing total abdominal hysterectomy were randomly divided into three groups. An epidural tube was inserted into one of the following three sites, Th11-12, L2-3, and caudal region. General anesthesia was then maintained with nitrous oxide-oxygen-enflurane, and pancuronium bromide. Morphine hydrochloride 2 mg in 8 ml of normal saline was administered into one of the designated epidural spaces one to two hours before the assumed end of surgery. Postoperative pain was assessed every four hours after the end of the operation until the next morning. Morphine exerted a relatively profound and prolonged analgesic effect in 40% of the Th11-12 group of patients, as well as in 6.7% of the L2-3 and caudal groups. But, supplementary analgesics were necessary in the other patients. No significant differences were found in the degree and extension of postoperative pain, as well as the doses of supplementary analgesics among the three groups. Adverse effects, such as nausea, vomiting and itching, occurred in 30 to 40% of each of the morphine administered groups. Though morphine was applied into different spinal levels, this clinical study did not show any difference in extension of analgesia. The epidurally applied morphine may be distributed widely in the spinal arachnoid space after some time, and may exert an effect on the brain as well as on the spinal nerves. When morphine is administered epidurally one to two hours before the end of a surgical operation, selection of an injection site according to the dermatome level of the skin incision may be unnecessary.

In the first part of this study, we compared the effects of morphine and trimebutine, two opioid receptor agonists, on small intestinal motility and plasma motilin in dogs. Morphine (100 micrograms/kg iv for 10 min) induced first a typical vomiting myoelectric profile followed subsequently by a migrating electrical activity mimicking phase III of the migrating myoelectric complex; trimebutine (5 mg/kg iv for 10 min) initiated only a migrating phase III-like activity. Despite their different initial contractile effects, both agents induced a significant and similar rise in plasma motilin that preceded the beginning of the premature phase III. In the second portion of the study, naloxone, an opioid receptor antagonist, was infused to verify the influence of endogenous opiates on plasma motilin and on the migrating motor complex. Naloxone (2 mg/kg, then 0.5 mg.kg-1.h-1 iv) delayed significantly the cyclic recurrence of plasma motilin peak increases and of the phase IIIs. In some animals, where naloxone abolished the phase IIIs, the amplitude of the motilin peak increases was significantly diminished. These results suggest 1) that opioid administration increases plasma levels of motilin by a mechanism that is independent of the intestinal contractile activity, and 2) that endogenous opioids could be physiological inducers of plasma motilin increases in the conscious dog.

The role of opioid and histaminergic system in morphine induced emesis was investigated in dogs. Morphine (25 micrograms, icv) consistently evoked emesis with an average latency of 195 +/- 29 sec which was fully accounted for by an action on the chemoreceptor trigger zone (CTZ) as its ablation rendered animals refractory to vomiting. Intraventricular pretreatment with opioid antagonist naloxone, histamine H1 antagonist mepyramine and H2 antagonists metiamide and cimetidine afforded protection to icv morphine emesis. The CSF histamine concentration was significantly raised 5 min after icv morphine administration. The results suggest that both endogenous opioid and histamine are involved in morphine emesis. Naloxone in high doses (1600 micrograms, icv) elicited emesis which was not blocked by CTZ ablation confirming our earlier report.

We performed a double-blind study of the dose-response relationship of intrathecal morphine (0, 0.3, 1, and 2.5 mg) for postoperative pain relief in 33 subjects who underwent total knee or hip replacement surgery. Assessments commenced 1 hour after the opioid injection, which was given at the end of surgery, and continued for 24 hours. Pain measurements, supplementary analgesia requirements, and adverse effects were recorded. Intrathecal morphine provided effective, long-lasting pain relief. All doses delayed the initial perception of discomfort (T-Pain) and also postponed the onset of severe pain requiring analgetic supplementation (T-Morphine) (1.25 hours control with placebo injections; greater than 20 hours with intrathecal morphine 0.3, 1, and 2.5 mg: P less than 0.05). Although 0.3 mg usually provided good analgesia it was unsatisfactory in three of 10 patients (30%), whereas 1 and 2.5 mg were absolutely reliable. Respiratory depression (increased PaCO2), common after the administration of 1 or 2.5 mg intrathecal morphine, was slow in onset and prolonged. The respiratory depression after 2.5 mg was more profound than after 1 mg, and produced apnea necessitating large-dose naloxone therapy. Pruritus was unique to intrathecal morphine administration, but nausea, vomiting, and urinary retention were common in all the groups. We conclude that no ideal dose of intrathecal morphine exists because, even with small quantities, minor adverse effects are evident. Doses between 0.3 and 1 mg, however, should provide good analgesia free from the major complication, respiratory depression.

Morphine derivatives are the most frequently used analgetic substances in obstetrics today. Nevertheless, nausea, vomiting, weariness, and somnolence are common side effects of these drugs. Moreover opiates exhibit a depressive effect on ventilatory activity. As many studies have demonstrated tramadol, a new analgetic substance amongst the opiates does not show a depressive effect to such a high degree. In this prospective randomized trial we compared the efficacy as well as the safety of 100 mg tramadol and 100 mg pethidine in 40 women asking for pain relief during labour. The duration of labour was slightly but not statistical significantly shorter in the pethidine group. An analgetic effect could be observed in the pethidine as well as the tramadol group by both the pregnant women and the attending physician about 10 min after application lasting for about 2 hours. Concerning the side effects tramadol highly contrasted with pethidine. There were less cases of weariness and somnolence and the ventilatory frequency of the newborn babies tended to be higher than in the pethidine group. The serum levels of tramadol in umbilical and maternal veins demonstrated values of 0.83 +/- 0.15 (mean +/- SEM; quotient). The results of this study seem to establish an analgetic effect of tramadol similar to pethidine but with less side effects.

Symptoms experienced by 227 consecutive patients before their admission to the coronary care unit were identified by questionnaire and those associated with myocardial infarction (98) compared with those occurring with ischaemia (53) and chest pain or discomfort of unknown cause (29). The diagnosis of myocardial infarction by the nature of the resultant pain or discomfort was unreliable in contrast to the associated symptoms sweating, nausea, belching and vomiting. The predictive value of the latter was 91%. Nausea was associated with inferior site of infarction and development of Q waves on the electrocardiogram. Morphine administration was not followed by an increased incidence of vomiting. Back pain or discomfort during infarction was experienced twice as often by women.

A prospective study of the effect and side-effects of epidural morphine for pain relief in 1085 patients after thoracic, abdominal, urologic, or orthopaedic surgery was performed. Morphine chloride was diluted in saline or bupivacaine and administered through an epidural catheter placed at a segmental level appropriate for the type of surgery. The initial dose was 4 or 6 mg morphine and supplementary doses were given when needed to obtain complete freedom from pain during deep breathing or nursing care. The total dose of epidural morphine from end of surgery until the next morning varied from 4 to 18 mg. 97% of hip arthroplasty patients, 91% of prostatectomy patients and thoracotomy patients, 90% of patients after major lower extremity surgery and 88% of patients after laparotomy were completely satisfied with the postoperative course. For hip arthroplasty and major extremity surgery, an initial dose of 4 mg of epidural morphine was as effective as 6 mg. After prostatectomy, laparotomy, and thoracotomy, an initial dose of 6 mg gave significantly better effect than 4 mg. Pruritus occurred in 11%, nausea or vomiting in 34%, and respiratory depression in 0.9% of the total patient population. Urinary retention occurred in 42% of patients not having urinary catheters in place. Postoperative nausea or vomiting was more frequent in women than in men (P less than 0.001). There was a higher incidence of nausea or vomiting in men experiencing pain than in men who were completely pain-free after abdominal surgery (P less than 0.001). Respiratory depression was rare and occurred as a gradually decreasing respiratory rate.(ABSTRACT TRUNCATED AT 250 WORDS)

Morphine sulphate 5 mg and placebo administered epidurally after caesarean section under epidural analgesia were compared in a double-blind fashion. Morphine was significantly superior to placebo for pain relief, duration of pain relief, and reduction of parenteral narcotic requirements. Pruritus was the most commonly encountered side-effect. There was no statistical difference between morphine and placebo in the incidence of urinary catheterisation, vomiting, nausea, dizziness or drowsiness. No serious respiratory depression requiring treatment was observed.
