The advantages of performing carotid endarterectomy in the awake patient, perioperative analgesia, circulatory parameters, plasma cortisol and PRL response to surgery have been evaluated. Ten patients were submitted to general anaesthesia and ten patients to superficial and deep cervical block. The Authors conclude that, although the number of patients studied is limited, there are no significant differences between the two groups for intraoperative analgesia, hemodynamic imbalance and plasma cortisol and PRL. This result support the belief that carotid endarterectomy in awake patients can be safely performed on patients with chronic obstructive pulmonary disease.

Plasma cortisol and PRL were measured in two groups of patients undergoing reconstructive aortic surgery under either general anaesthesia and continuous epidural analgesia with supplemental general anaesthesia. The results confirmed that epidural analgesia with light general anaesthesia is much able than general anaesthesia to suppress the metabolic response associated with aortic surgery procedures.

We can state that an effective pain relief during labour, like epidural analgesia, is indicated and it prevents or modifies the pain-induced harmful effects on mother and the fetus. Maternal and fetal ACTH or BE response in labour are not altered, but the increase of maternal cortisol secretion is reduced, thus probably suggesting a lesser maternal stress, to which also point the changes of PRL. Epidural analgesia prevents harmful maternal metabolic changes like hyperventilation, hypocapnia, metabolic acidosis and lactic acid accumulation. These beneficial effects are also reflected in a better fetal and neonatal condition. Carbohydrate and fat metabolism, on the contrary, seem not to be significantly changed by epidural analgesia. Epidural analgesia is beneficial also by reducing the pain induced catecholamine release, and by improving the intervillous blood flow, especially in pre-eclamptic parturients.

New data on tachykinins and bombesins are displayed and the present situation of research on the novel amphibian skin peptides sauvagine and dermorphin is illustrated. The potent stimulant effect of sauvagine on ACTH and beta-endorphin release has been confirmed both in vivo and on columns of isolated and dispersed rat pituitary cells, and similarly the potent inhibitory effect on PRL and GH release, both in the rat and man. Particular emphasis is laid on the occurrence of sauvagine-like immunoreactivity in fish urophysis and in amphibian nervous structures, including the retina. It is suggested that the long-searched corticotropin releasing factor and PRL release-inhibiting factor may be a sauvagine-like peptide. Dermorphin, in its turn, has been found to cause, by intracerebroventricular injection, not only analgesia and catalepsy, but also conspicuous EEG and behavioral changes in the rabbit and chick, as well as a sharp reduction in gastric emptying time and gastric acid output in the rat, together with marked stimulation of PRL release.

High doses of GH, used to induce anabolism in prolonged critically ill patients, unexpectedly increased mortality. To further explore underlying mechanisms, a valid animal model is needed. Such a model is presented in this study. Seven days after arterial and venous cannulae placement, male New Zealand White rabbits were randomly allocated to a control or a critically ill group. To induce prolonged critical illness, a template controlled 15% deep dermal burn injury was imposed under combined general and regional (paravertebral) anesthesia. Subsequently, critically ill rabbits received supplemental analgesia and were parenterally fed with glucose, insulin, amino acids, and lipids. On d 1 and d 8 after randomization, acute and chronic spontaneous hormonal profiles of GH, TSH, and PRL secretion were obtained by sampling blood every 15 min for 7 h. Furthermore, GH, TSH, and PRL responses to an iv bolus of GH-releasing peptide 2 (GHRP-2) + TRH were documented on d 0, 1, and 8. Hemodynamic status and biochemical parameters were evaluated on d 0, 1, 3, 5, and 8, after which animals were killed and relative wet weight and water content of organs was determined. Compared with controls, critically ill animals exhibited transient metabolic acidosis on d 1 and weight loss, organ wasting, systolic hypertension, and pronounced anemia on d 8. On d 1, pulsatile GH secretion doubled in the critically ill animals compared with controls, and decreased again on d 8 in the presence of low plasma IGF-I concentrations from d 1 to d 8. GH responses to GHRP-2 + TRH were elevated on d 1 and increased further on d 8 in the critically ill animals. Mean TSH concentrations were identical in both groups on d 1 and 8, in the face of dramatically suppressed plasma T(4) and T(3) concentrations in the critically ill animals. PRL secretion was impaired in the critically ill animals exclusively on d 8. TSH and PRL responses to GHRP-2 and TRH were increased only on d 1. In conclusion, this rabbit model of acute and prolonged critical illness reveals several of the clinical, biochemical, and endocrine manifestations of the human counterpart.
