In chronic experiments on rats it was established that electric stimulation of certain areas of the midbrain depresses pain reactions of different genesis. Morphine in subanalgetic doses (2--2.5 mg/kg) reveals and potentiates the antinociceptive effect of central stimulation shown first of all by depression of the complex highly integrated components of an emotionally behavioral conductive reaction to pain.

1. A therapeutic trial of intravenous hematin is presented. Eleven cases of AIP and one of VP who did not improve with conventional treatment (high carbohydrate intake) received this new agent. 2. Urinary ALA, PBG and, when possible, uroporphyrin and coproporphyrin were used to monitor the chemical response to the treatment. Objective clinical parameters of hypertension and tachycardia were followed when present in addition to subjective estimates of acute porphyric symptomatology (abdominal pain, backache, extremity pain and paresthesias, weakness, depression, etc.). 3. At a dosage of approximately 3 mg/kg, diminution of urinary ALA and PBG excretion was achieved in every patients. Hypertension and tachycardia improved in those instances where they were observed in association with the attack. Also, subjective improvements in the clinical status of the patients were observed frequently. 4. Hematin appears to be a promising therapeutic agent for the treatment of acute attack forms of porphyria.

The analgesic effect of nicomorphine in two different solutions was tested in 120 patients after cholecystectomy. The patients were divided into three groups: group I was given nicomorphine diluted with water, group II nicomorphine diluted with propylenglykol, group III propylenglykol alone. The degree of pain sensation was determined by interrogation. Pulse, respiratory rate, blood pressure as well as capillary pO2 and pCO2 were measured 10 and 30 minutes after medication. No difference in pain relief could be established in the two groups receiving nicomorphine. Respiratory depression with a significant decrease of respiratory rate together with an increase of pCO2 was observed in the two nicomorphine groups. In the placebo group there was no significant change in the tested parameters. A small decrease of pO2 was observed in all patients after laparotomy.

Many cyclic changes during the menstrual cycle (temperature, depression, motor activity, pain sensitivity, etc.) are closely paralleled by changes in brain serotonin level. These changes, in turn, are associated with peripheral hormone levels which are comparatively regular and easily measured. Their measurement may be useful both in predicting behavior and in accounting for atypical menstrual-related behavior.

In a randomised trial postoperative pain relief was provided by either epidural injections of bupivacaine or an infusion of fentanyl adjusted by the patient to achieve adequate pain relief. Both techniques produced satisfactory analgesia without respiratory depression after peripheral arterial surgery. The technique of infusing intravenously a potent analgesic in a dose adjusted by the patient appears to offer several advantages in postoperative care.

A comparison was made between the physical and emotional changes experienced by patients, nursing personnel, and physicians with 2 different mid-trimester abortion techniques. 250 dilatation and extraction (D and E) procedures under general anesthesia were compared with abortions by intraamniotic injection of prostaglandins. The only major difference between the 2 sets of patients was that the amnio patients were further along in their pregnancies. At a 3-week follow-up interview, the patients differed significantly in their reactions. The D and E group had fewer complications and described the procedure as minor surgery which went smoothly. The amnio group had experienced more pain and had greater feelings of guilt, anger, and depression. The floor nursing personnel felt anger at being abandoned by the doctors to deal alone, usually in the middle of the night, with the difficult experience of an amnio delivery of a dead fetus. Operating room nurses and doctors found the D and E procedure distasteful and emotionally disturbing. Doctors perferred to perform amnio procedures and not be involved at the time of delivery. The authors' experience leads them to conclude that the D and E procedure is safer, less painful, quicker, more convenient, and less expensive for the patient than the amnio procedure. The psychological problems doctors experience with dismemberment of the fetus may be relieved with development of new techniques.

The success of a total hip replacement surgery, using the hip evaluation form, was investigated in 2 groups of surgical patients which differed in terms of relative success of surgery. For the men, the group which did not respond as well to surgery had less education and were more retired individuals; this group also had more pain, less ambulation, and greater functional handicaps prior to surgery. For the women, there were no significant differences between the groups with regard to the demographic variables and the hip evaluation measures prior to surgery. The Minnesota multiphasic personality inventory administered following surgery suggests that the women who did not respond as well to surgery had more physical symptoms, anxiety, depression, and difficulties in relating to people.

The effects of 2 doses of nefopam, d-amphetamine, pentazocine, and placebo were studied in healthy male sleep-deprived volunteers to determine whether the drugs improved or impaired coordination and whether they induced subjective effects. A critical tracking task was used to study hand-eye coordination. D-amphetamine, 10 mg orally, significantly improved tracking performance and made subjects feel better able to perform tasks but more anxious. It also made them feel more alert, steady, sociable, and strong. Pentazocine, 45 mg intramuscularly, caused deterioration in tracking performance and was followed by reports of depression, gloominess, dreaminess, nausea, and injection site pain. There was no significant change in tracking performance or subjective effects after both doses of nefopam and placebo.

Clomipramine is the most potent 5-HT reuptake blockade agent among the antidepressants. A comparison between the effect of clomipramine and a less powerful 5-HT reuptake blockade agent (amitriptyline) could test the hypothesis that brain 5-HT is a mediator of pain sensation. Groups of patients of either sex, with pain indication of trigeminal neuralgia, tension headache or postherpatic neuralgia, received doses of clomipramine or amitriptyline in a single blind clinical experiment. The results after three months of treatment showed that clomipramine: (1) was better than amitriptyline in treating trigeminal neuralgia; (2) tended to be better in the treatment of tension headache; and (3) amitriptyline is better in treating postherpatic neuralgia. Clomipramine was better tolerated. The results support the hypothesis that in certain pain situations, clomipramine exerts a beneficial effect, not only because of its effect on the depression and anxiety level of the patient, but also via its effects on the 5-HT brain system.

Hemodynamic monitoring and care of the patient at high risk for anesthesia require a careful and systematic approach. During preoperative evaluation the patient at increased risk must be identified and correctable problems must be solved. The patient's current medications must be reviewed because they may influence the choice of anesthetic approach and may alter the physiologic response to the stresses commonly associated with anesthesia. In addition to conventional clinical and electrocardiographic monitoring, perioperative hemodynamic monitoring may be desirable for patients at special risk, who are likely to have significant associated medical problems or to undergo complicated surgical procedures. No ideal induction agent exists, and hypotension secondary to peripheral vasodilation or myocardial depression, or both, is a potential problem. Patients with an inordinately high risk may benefit from mechanical circulatory assistance prior to induction of anesthesia. Attention to oxygenation, blood volume replacement and the prevention of hypertensive episodes are particularly important during anesthesia so that optimal cardiac performance is ensured and ischemia avoided. The stresses during emergence from anesthesia contribute to lability of the cardiovascular status and hypoxemia. The period of risk does not conclude with immediate recovery from anesthesia but extends through the postoperative phase. Careful monitoring and attention to the control of pain, prevention of hypotension and hypertension, adequate oxygenation, early mobilization and resumption of the administration of cardiac medications are important factors in a successful outcome.
