Autonomic correlates of illness imagery.

Psychophysiological responses to imagery of self-relevant illness threats were examined for high and low extreme groups of hypervigilants and health care utilizers. Heart rate, skin conductance, and respiration were the physiological measures recorded; self-reports of perceived illness vulnerability, negative affect, image clarity, and image realness were the psychological measures obtained. Responses to neutral, exercise, and illness threat scenes were compared. Hypervigilants showed an increased heart rate response to imagery of illness scenes, whereas all other groups returned more quickly to baseline levels. The results are similar to those reported by Lang for snake phobics. They also lend some support to Horowitz's theory of intrusive imagery, in which self-relevant, anxiety-provoking events tend to continuously intrude upon one's thoughts, and this intrusive imagery was reflected cardiovascularly. There could be several possible underlying mechanisms for these findings.

Severe hypotension from epidural meperidine in a high-risk patient after thoracotomy.

A sixty-eight-year-old female developed severe hypotension immediately after the administration of epidural meperidine for post-thoracotomy pain. Two preceding injections of epidural opiates had been uneventful. The cardiovascular collapse was difficult to reverse and may have contributed to the patient's subsequent death. Cardiovascular complications have not been reported frequently as a possible side effect of epidural opiate analgesia.

Gastro-intestinal haemorrhage from peptic ulcer. An evaluation of bloodless transfusion and early surgery.

Over a 3-year-period 72 patients with upper digestive tract haemorrhage due to peptic ulcer were transfused exclusively with isotonic sodium chloride and glucose solutions in equal quantities. The results are compared with 69 patients treated previously in whom conventional blood transfusion regimes had been used. Transfusion therapy was combined with emergency surgery involving vagotomy and draininage, with surgical haemostasis in situ. There were no significant differences between the two groups with regard to anaesthesia, surgery and post-operative managemement. Apart from anemia, there were less early and late complications in the group not receiving blood. The amount of crystalloid solutions administered varied between 7000 ml and 19,000 ml causing a diuresis of 1000 ml to 5300 ml within the first 24 hours. The use of this transfusion regime for haemodynamic re-equilibration in upper gastro-intestinal haemorrhage due to ulcer, in cases in which haemostasis can be obtained with certainty by emergency surgery, allows transfusion of stored blood and colloid solutions to be avoided and emergency surgery to be safely undertaken at the earliest moment. The severe acute anaemia which is caused appears to create no special problems.

[Upper digestive hemorrhages of ulcerous nature (management and experience)].

A number of 135 cases were examined, presenting with superior digestive hemorrhage of ulcerative origin. The analysis of the cases was made by two comparable groups. In the first one of the groups the volemic re-equillibration was based on the administration of blood and surgery was carried out, in principle, on a "cold" condition. In the second group volemic re-equillibration was achieved exclusively with isotonic non-colloidal volemic solutions that were administered before, during and after surgery (0.9% NaCl solution and 5 g% glucose solution in equal amounts). Surgery was performed as an emergency and vagotomy was made, as well as surgical hemostasis. The results obtained have allowed for the conclusion that, by providing efficient surgical hemostasis and volemic re-equillibration with isotonic non-colloidal solutions blood transfusion and its untoward side-effects can be avoided.

[Gastric consequences of toxicoseptic agression].

This study is concerned with gastro-secretory and motor answers. It was carried out in two groups of patients and the results obtained were compared. The following aspects were noted: a. the control group was represented by 10 patients that had been exposed to anesthesic-surgical aggression; b. the second group was formed by 20 patients with toxico-septic syndrome of various etiologies and in different stages of evolution; - secretory and motor gastric disturbances take on an evolutive dynamic character, according to the clinico-biological phase of the syndrome; in the acute stage absolute hypersection is noted, as well as from the viewpoint of the rate, of hydrochloric acid, and gastric hypomotility; in the chronic stage there is acid hyposecretion both insulin- and histamine-resistant and in 30% of the cases there is anachlorhydria; to the general-metabolic phase of inversion corresponds, at the gastric level; a return to normal of the motility and of the acid gastric secretion.

[The value of non-specific general therapy of shock caused by acute pancreatitis].

The shock in general, including that of acute pancreatitis, presents, according to our conception, as an energetic disease involving primarily the cell (by the intensive catabolic processes induced by the pancreatic lesion) and secondarily the most peripheral and mobile sector, that of the hemodynamic compartment. There is no etiological treatment of pancreatitis (the exceptions are very rare), and this is the reason for which we adopt a conservative attitude, and medical treatment, in the acute stage of the disease. The basic treatment of the shock of acute pancreatitis is considered to be the re-establishment of the circulatory volume with the aid of non-colloidal isotonic solutions that are given in large amounts (8-17 liters in a 24-hour period) under continuous perfusion. This technique is called hyperhydration or transrenal dialysis. Making use of this technique in the treatment of shock occurring in the course of acute pancreatitis the death-rate recorded was as low as 2,3% and the number of complications was very low.

[Evaluation of therapeutic measures in toxicoseptic states].

Based on observations made in 112 cases of toxico-septic conditions that had developed in surgical and obstetrical conjunctures, the authors propose a unified codification of the major therapeutical means (etiologic therapy, general, non-specific and specific therapy, adapted for functions and organs). The removal, or surgical draining of the septic focus is the most efficient therapy of toxicoseptic conditions of surgical or obstetrical origin. Compared to this method all the other therapeutical methods are secondary or adjuvant. The authors have acquired a vast experience in the use of a device for peritoneal washing-draining in cases with toxico-septic syndrome of surgical and obstetrical origin. General, non-specific therapeutic measures for quantitative and qualitative maintenance of the internal environment of the organism are achieved with relatively large amounts of non-colloidal crystalloid isotonic solutions, administered over the entire duration of the toxico-septic condition. The importance of the specific therapy is stressed, adapted for functions and organs, stressing amost particularly the therapeutical measures in which the authors have acquired extensive experience.
