The authors used techniques of pure anesthesia analgesia with Fentathienyl-Pavulon, or anesthesia and analgesia potentialised with Fentathienyl-Flunitrazepam, or Pentothal-Fentathienyl-Pavulon on various series of patients. The study was oriented on changes in the sympathetico-adrenalin pituitary response, and the use of glucose under the effect of these techniques. There was noted a fall in plasma cortisol levels, a fall in urinary excretion of catecholamines, an increase in growth hormone and better peripheral use of glucose. A comparative study was carried out with similar techniques using morphine, pentazocine or fentanyl.

Plasma concentrations of glucose, insulin, glucagon, cortisol, growth hormone and prolactin were measured repeatedly in ten females undergoing abdominal hysterectomy during general anaesthesia. In addition to general anaesthesia five of the patients had continuous epidural analgesia effective for the first 26 postoperative hours. Plasma glucose was elevated during surgery and postoperatively, but not in patients having epidural analgesia. Insulin was low and unchanged in both groups. Glucagon was unchanged and similar in both groups. Cortisol was lower during surgery in the epidural group, but not postoperatively. Growth hormone increased during surgery in four of five patients receiving general anaesthesia alone, but no changes were observed in the epidural group. Prolactin was greatly elevated in all patients immediately after induction of anaesthesia and then fell rapidly during surgery, similarly in both groups. It is concluded that epidural analgesia can inhibit the hyperglycaemic response to surgical stress, but this effect cannot be uniformly correlated to changes in peripheral plasma levels of insulin, glucagon, cortisol, growth hormone or prolactin.

Nineteen patients undergoing elective gastrointestinal surgery were randomised to receive recombination human growth hormone (n = 9) or placebo (n = 10) for the first five postoperative days. All received epidural analgesia and total parenteral nutrition during the same period (energy supply 125% of basal metabolic rate, mean nitrogen (+/- SEM) 5.7 (+/- 0.1) g/m2). Nitrogen and potassium retention was induced in the growth hormone group compared with the placebo group (cumulative nitrogen balance 4.1 (+/- 1.1) g/m2 in the growth hormone group and -3.1 (+/- 1.8) g/m2 in the placebo group, p less than 0.01; cumulative potassium balance 80.8 (+/- 4.7) mmol/m2 in the growth hormone group and 43.1 (+/- 11.4) mmol/m2 in the placebo group, p less than 0.01). In the growth hormone group, serum glucose concentrations increased each evening and mean serum albumin concentrations were reduced throughout the period; the morning pulse rates were decreased, and the patients gained weight compared with the placebo group.

Plasma concentrations of glucose, lactate, epinephrine, norepinephrine, insulin, cortisol and growth hormone were measured in 28 healthy children, three to six years of age, before, during, and after lower abdominal surgery. The children received premedication with secobarbital, 6 mg.kg-1, pentazocine, 0.5 mg.kg-1, and atropine, 0.01 mg.kg-1 im. Fourteen children received general anaesthesia with nitrous oxide and halothane, and 14 others received caudal analgesia with 1.5% mepivacaine. Plasma glucose, epinephrine and norepinephrine concentrations remained unchanged in the general anaesthesia group, but decreased during and after surgery in the caudal analgesia group (P less than 0.05). During surgery, these concentrations were different between the two groups (P less than 0.05). Plasma insulin and cortisol concentrations increased after surgery (P less than 0.05), and growth hormone concentration increased during and after surgery in the general anaesthesia group (P less than 0.05), but the concentrations of these hormones remained unchanged during and after surgery in the caudal analgesia group. Plasma lactate concentrations were unchanged in both groups. These results indicate that caudal analgesia suppresses the metabolic and endocrine responses to stress associated with lower abdominal surgery in children.

443C81 is a synthetic enkephalin thought to act on peripheral opiate receptors. The analgesic, central, cardiovascular and endocrine effects of two i.v. doses of 443C81 were investigated in 12 healthy male volunteers. Its effects were compared with those of placebo and the classical opiate dipipanone given orally using a double dummy design. 443C81 produced dose-related analgesia; dipipanone 10 mg had a greater effect than the high dose 443C81. In contrast to dipipanone, 443C81 did not cause significant miosis or reduce minute volume on rebreathing CO2 and there was no evidence of sedation. Dry mouth was reported frequently and associated with reduced salivation after all active treatments. Both 443C81 and dipipanone increased circulating prolactin and growth hormone and reduced cortisol levels. This novel enkephalin appears to possess analgesic activity and some other properties of opiates but is devoid of clinically relevant narcotic effects.

Sixteen cases of adverse effects due to a new health-food product, gamma-hydroxybutyrate (GHB), were reported to the San Francisco Bay Area Regional Poison Control Center in the 5-month period from June to October 1990. Cases have also been reported in eight other states. Adverse effects included coma (four patients) and tonic-clonic seizurelike activity (two patients). Doses ranged from 1/4 teaspoon to 4 tablespoons. Acute symptoms resolved within 7 hours. GHB was investigated as an anesthetic agent during the 1960s until seizures and lack of analgesia precluded its use. It was recently introduced in the health-food market as a food supplement for body builders with claims of anabolic effects by stimulating growth hormone release. GHB remains under investigational new drug status with the Food and Drug Administration and is illegal for over the counter sale. The Food and Drug Branch of the California Department of Health Services has prohibited further sale of this product in California as have health departments in Florida and South Carolina; however, new cases continue to be reported. Health professionals should be aware of the potential health hazards of GHB.

To determine whether the differences in development of acute tolerance to several morphine actions correlate with the mu receptor subtype mediating them, we have examined the appearance of acute tolerance to analgesia, respiratory depression, gastrointestinal transit, and hormone release in an intravenous morphine infusion model. Analgesia, a naloxonazine-sensitive mu1 action, peaked at 2 hr after initiation of the infusions. The log dose-response relationship of the infusion rate to peak tailflick latency was linear from 10 to 50 micrograms/kg/min. By 8 hr, the tailflick latencies declined nearly to baseline levels, implying the rapid development of tolerance. Tolerance to morphine-induced prolactin release, another mu1 action, also developed rapidly over 8 hr. In contrast two mu2 actions, respiratory depression measured with arterial blood gas, determinations and gastrointestinal transit, showed no significant tolerance over a similar 8 hr infusion. We also observed no tolerance to morphine-induced growth hormone release, a non-mu1 action, over the same period. Thus, these results demonstrate that mu1 actions develop tolerance in an infusion model far more rapidly than a number of naloxonazine-insensitive (non-mu1) ones and may help explain differences in the rate of tolerance development to morphine actions.

We have studied the metabolic and hormonal responses to surgery, and the pain scores and analgesic requirements in 24 patients undergoing cholecystectomy, allocated randomly to three groups to receive either general anaesthesia alone, or general anaesthesia with extradural diamorphine 0.1 mg kg-1, or general anaesthesia with extradural somatostatin to a total dose of somatostatin 3 mg. The only significant effect of extradural diamorphine was a decrease in the glucose response to surgery. Somatostatin 3 mg by the extradural route caused a significant increase in the concentration of circulating somatostatin which resulted in a significant decrease in plasma growth hormone and insulin after 60 min of surgery, together with an increase in plasma glycerol concentration. Patients in the diamorphine group required significantly less i.v. analgesia in the postoperative period than the other two groups. Intraoperative somatostatin failed to provide any postoperative analgesia.

The effects of epidural analgesia on plasma calcitonin gene-related peptide (CGRP) values during and after hysterectomy were investigated in 14 healthy patients. In seven patients who received general anaesthesia alone for pelvic surgery, there were no significant changes in plasma CGRP concentrations. In the remaining patients, who received extensive epidural blockade in addition to general anaesthesia, there were again no significant changes in plasma CGRP values. This was in spite of profound sympathetic blockade, as shown by marked hypotension and a significant decline in plasma catecholamines. The epidural group of patients showed the expected attenuation of the glucose, cortisol and growth hormone responses to surgery. The results show that circulating CGRP is unlikely to be involved in the modulation of peripheral vascular tone during pelvic surgery under either general or epidural anaesthesia.

The naturally occurring peptide human beta-endorphin-(1-27) (h beta-EP-(1-27) has been shown to antagonize beta-endorphin (h beta-EP)-induced analgesia. We have evaluated the effects of the fragment on h beta-EP-induced growth hormone (GH) and prolactin (PRL) release. It inhibited beta-EP-induced GH release in a dose-related way but left beta-EP-induced PRL stimulation unchanged.
