[Effects of combination alfaxalone and alfadolone, anesthetic derivatives of pregnanedione, on cerebral hemodynamics in cats].

Intravenous injection of CT 1341 (a mixture of alphaxalone and alphadolone dissolved in cremophor el) induced a decrease in cerebral blood flow (CBF) measured by 133Xe clearance in cats with artificial respiration (the mean reduction in CBF was 2 ml/100 g/mn for 1,2 mg/kg or CT 1341. So, CBF was decreased by 22% when CT 1341 (7,2 mg/kg) was intravenously injected, (mean Pa CO2 equals 30 mm Hg). Changes in CBF following CT 1341 intravenous injection seems to be caused by cerebral vascular constriction evidenced by the direct observation of pial vessels. Following intravenous injection of CT 1341 (from 7, 2 mg/kg to 19,2 mg/kg), the cerebrovascular reactivity to hypercapnia or hypocapnia was not affected, but autoregulation of cerebral blood flow was transiently abolished. In animals with free respiration, CBF was increased in relation with the elevation in Pa CO2 caused by the depression of respiration.

[A case of tracheal amyloidosis discovered during observation of interstitial pneumonia].

A 73-year-old man was admitted to our hospital because of fever, productive cough and dyspnea on exertion in March 1998. He had been treated at our hospital for interstitial pneumonia. Chest radiographs showed consolidations and honeycomb shadows in both lungs. He also had a chronic subdural hematoma. After admission his respiratory state deteriorated and the chronic subdural hematoma increased in size and as a result, artificial respiration was needed. During intubation for bronchoscopy, we found protuberant white lesions in the tracheal mucous membrane, a biopsy of which showed amyloid deposition. Immuno-histochemistry revealed AL-amyloid, although there was no amyloid deposition else where. This was an idiopathic case in which localized tracheal amyloidosis probably developed in association with interstitial pneumonia.

[Effect of gentle nursing care of premature infants on bonding and emotional development of the child. Follow-up of premature infants in Dr. Marina Marcovich's study].

The study was set out to investigate whether the Marcovich model of a "soft treatment" of premature infants encourages the parent-infant-relationship to such an extent that, at school age, the Marcovich-children would be found to differ significantly from children treated with standard care with regard to the quality of their attachment and the prevalence of emotional and behavioural disorders. The Marcovich-children of the present sample had been discharged from hospital much earlier than the standard group, they were less frequently treated with artificial respiration, infant-parent body contact was encouraged significantly earlier, and, although they were less frequently breast-fed, those who were breast-fed were allowed to do so at a much earlier stage. The Marcovich-children were found to display higher social competence, more emotional openness, more emotional coherence, less dismissal of attachment and less preoccupied anger. The two samples did not differ with regard to their total attachment quality as well as their emotional and behavioural problems. The fact that no significant differences could be established with regard to the quality of the attachment suggests that the complex life-saving attachment system is not irreversibly affected by the early separation and distress and that the months and years after the hospital stay have the power to make up with any experienced trauma. It seems, however, that special aspects of the attachment system, such as the communication and interaction, are positively encouraged and enhanced by the soft treatment of the premature infant, which leads to greater emotional openness and social competence, as well as less preoccupied anger against the attachment figures.

[Theophylline toxicity in a patient with status asthmaticus].

A 70-year-old woman was hospitalized for status asthmaticus. The level of CRP was high and chest roentgenogram showed infiltrative shadows in the left middle lung field. Artificial respiration and continuous infusion of methylprednisolone and aminophylline 750 mg/24 hr were performed. Eight hours after admission, seizures suddenly occurred. At this time, brain CT showed no abnormal findings. The seizures were thought to be induced by theophylline toxicity, since serum theophylline concentration was high at 69.9 micrograms/ml. Because theophylline clearance of the patient in a clinically stable condition was normal, it was speculated that theophylline clearance was reduced during status asthmaticus. It is thought that this rare case of theophylline toxicity occurred due to reduction of theophylline clearance during status asthmaticus associated with pneumonia.

[Irreversible coma following hypoglycemia in Sheehan syndrome with adrenocortical insufficiency].

A 24-year-old woman of Somali origin delivered at term after an uncomplicated pregnancy. Post-partum haemorrhage resulted in hypovolaemic shock which was treated by hysterectomy. Five days later she became comatose due to unrecognised hypoglycaemia which caused severe irreversible brain damage and status epilepticus. Treatment in the intensive care unit with artificial respiration, prednisolone, desmopressin, inotropic support, barbiturates and an anaesthetic under EEG guidance was unsuccessful. The patient died 28 days post-partum. The hypoglycaemia was due to a combination of (a) inadequate glucose intake and (b) lack of counter-regulatory mechanisms due to a deficiency of steroids and growth hormone as a result of loss of pituitary function (Sheehan syndrome) together with adrenocortical insufficiency. The combination of Sheehan syndrome and primary adrenocortical insufficiency has not been described previously in the literature.

Adventures in the study of breathing.

Perfect coordination is required between the amount of air breathed to ventilate the air cells of the lungs and the amount of blood pumped through them by the heart.Over-ventilation often accompanies severe emotional disturbances with far-reaching effects on the functions of the brain and other organs. Of particular interest are the effects of altering breathing upon angina pectoris. In conditions with under-ventilation the effects are serious because the carbon dioxide which accumulates acts as a narcotic on the nerve centers which control breathing. If oxygen is given to such patients they may be made much worse and become unconscious. Morphine and other narcotics also make matters worse.Under-ventilation in patients with over-distention of the air cells of the lungs results in a chronic form of carbon dioxide poisoning, so that the lungs may fail in ventilatory function. Recent work by Whittenberger has shown how to combat this situation by mechanical over-ventilation. As the excess of carbonic acid is removed the narcotic effect of the gas is lessened and the nerve center governing breathing resumes more normal operation under which the effect of oxygen is no longer deleterious.

Infant survival in prematurity.

Reduction of neonatal mortality and the rate of stillbirth may be expected from improved management of spontaneous labor and delivery.Neither roentgenographic measurement nor the inception of fetal movement or heartbeat nor any other single test is an index of fetal maturity; all must be considered together. Prenatal care, particularly supplemented diet, will help to avoid premature delivery, or at least to prolong pregnancy; since the fetus undergoes accelerated growth during the last weeks of pregnancy, even slight extension of gestation increases the chances for survival. Analgesia in the first stage of premature labor is contraindicated. Only low spinal anesthesia and other types of conduction anesthesia should be employed for later stages. The fetal membranes should be preserved as long as possible, but premature rupture does not call for immediate termination of pregnancy. Deep episiotomy and prophylactic outlet forceps are routinely employed to hasten the second stage of premature delivery and to protect the immature fetus. Breech presentation is managed by unassisted expulsion or by forceps extraction of the head. The umbilical cord is not immediately severed on delivery; administration of oxytocic drugs after the second stage of labor, combined with gentle stripping of the cord, results in rapid transfer of increased amount of placental blood. The airways of the infant should be immediately cleared. Artificial respiration may be necessary and it must be gentle.All premature infants should receive supplementary oxygen to render breathing regular and more efficient. They should be insulated immediately in controlled temperature and humidity, and they should be handled little.

[Excito-motor action of succinyldicholine and other cholinic esters on the spinal cord of the mouse].

We have realized on mice the spinal animal experiment, cutting the spinal chord below the bulb during artificial respiration. We have observed that the cholin esters and particularly the succinyldicholin injected into a caudal vein produce muscular contractions, of which we give a graphic. After having discussed these experimental results, we conclude that every cholin ester has an excitatory effect on the spinal chord. It must now be determined which of these esters is the normal medullary transmitter.

[A case of acute right ventricular infarction and life-saving right ventricular assistance following emergency coronary revascularization and resection of a left ventricular aneurysm--discussion of indication and proper assist flow volume].

Right ventricular assistance (RVA) using centrifugal pump in combination with IABP was used to treat a patient who was difficult to wean from a cardiopulmonary bypass following emergency coronary revascularization and resection of a ventricular aneurysm performed to treat acute right ventricular infarction due to a PTCA complication. After 131 hours of RVA at 3.2 to 4.8 l/min, it was possible to remove the pump. No heparin was administered during this time, changing the pump head twice, was used for 64 and 50 hour period, no thrombi were detected either time. After being weaned from RVA, the patient developed severe respiratory dysfunction, but on the 10th postoperative day (POD) IABP was weaned, and on the 13th POD the artificial respirator was withdrawn. The results of the postoperative cardiac catheterization were favorable, the patient was discharged on the 57th POD, and has returned to society at the present time. The indications for RVA include a central venous pressure > 20 mmHg and a cardiac index < 1.8 l/min/m2, and tissue perfusion pressure and general preoperative condition should severe as guides. The higher the assisted flow volume the more efficacious in relieving ventricular load, but, since there is a limit to how much the left ventricle and lungs can withstand, it should not exceed levels which ensure the maintainance of cardiac output and tissue perfusion pressure.

Medical aspects of chemical warfare.

The first-aid treatment of mass casualties from nerve gas relies mainly upon the use of drugs, and provision for their self-injection is recommended. Means for giving artificial respiration must also be provided, even though its large-scale use is regarded as impracticable. Prophylactic oxime (2 g. PAM chloride orally) is recommended if the situation permits. Some nerve gases are extremely rapid in action, and following exposure (or suspicion of exposure) 4 mg. of atropine and 2 g. of PAM chloride should be injected intramuscularly without delay. Preferably, atropine should be given intravenously. At the same time any clothing contaminated with liquid nerve gas should be removed and the skin cleansed thoroughly with a suitable fluid. Following this, the casualty should be watched closely for one hour. If poisoning develops despite these measures, or is already established, injection of atropine should be continued at short intervals until improvement occurs.
