[Peri-operative care of diabetics (author's transl)].

The generally accepted principles of treatment of a diabetic as a case for operation or emergency are listed and substantiated with reference to the varied pathophysiological processes. In particular the preoperative attitude of the diabetic and the special anesthesiological problems are gone into.

[The transcutaneous electrostimulating anaesthesia--the results of patients with retinal and vitreous surgery (author's transl)].

The clinical results of 50 patients with retinal and vitreous surgery performed in combined electrostimulating anaesthesia are reported. Premedication consisted of a barbiturate such as medomin and of atosil, ordered the evening before surgery. 1/2 hour preoperatively 1.5--2 ml thalamonal and 0.5 mg atropine were administered intramusculary. All patients were intubated and controlled respirated; stimulation starting about 5 minutes following intubation procedure. During continuous intermittent relaxation anaesthesia was maintained by a mixture of nitrous oxide/oxygen 1:1 and electrical stimulation at the dermatoms of N. trigeminus I, II and Plexus cervicalis 3 and 4. For the first time stimulation of the dermatoms during anaesthesia was done by self adhesive electrodes. So we were able to eliminate the circumstantial and not even harmless invasivity of the needle technique. The main advantages of the new method we see in a good circulatory stability and in good postoperative cooperation of the patients. Especially in old and poor risk patients the results of transcutaneous electrostimulating anaesthesia are excellent.

The effect of premedicants upon the lower oesophageal sphincter.

The barrier function of the lower oesophageal sphincter is of great practical importance in the prevention of regurgitation and aspiration. The action of seven most commonly used premedicants upon the lower oesophageal sphincter was studied in ten healthy volunteers. The results were compared with a placebo injection in eight volunteers. Sodium pentobarbital, droperidol and triflupromazine increased the presenting pressure of the lower oesophageal sphincter. Decreases were observed after promethazine, pethidine, the combination of droperidol plus fentanyl and atropine.

[Premorbid personality of monopolar and bipolar depressives. A comparison based on personality inventories (author's transl)].

Premorbid personalities are studied in 65 monopolar endogennous depressives (ICD-Nos. 296.0, 296.2) and in 45 bipolar depressives (ICD-No. 296.3) by a retrospective self-rating evaluation after recovery. The instruments used are two questionnaires of v. Zerssen, especially constructed for that purpose, along with the AUPI questionnaire, which is based on Eysenck's system of personality description. The two groups are compared according to each test scale. Significant differences result in two of the scales. Monopolar depressives score higher than bipolars in the scale representing Tellenbach's "melancholic type". This can be described with terms such as orderly, strenous, and conscientious. Bipolars show more extroversion than monopolars. None of the patients' groups can be distinguished fr-m the normal population in any of the AUPI scales (extroversion, neuroticism, and psychoticism).

[Hypertension and anesthesia (author's transl)].

Five to six millions of hypertensives live in the Federal Republic of Germany. Of these, about 70% are known to be hypertensives but only 30% are consistently treated. It is therefore not surprising that hypertension is one of the most common risk factors in patients who have to be operatively treated. The commonly approved principles of hypertensive therapy are compiled in the present study and classified with reference to the multivarious pathophysiological processes. In particular, special anesthesiologic problems are dealt with in detail. Furthermore, this paper provides the basic knowledge of the artificial fall in blood pressure under anesthetic conditions.

[Complications of regional anesthesia (author's transl)].

In spite of the great advances in anesthesia, regional anesthesia has not lost its importance. The development of new, longer-acting local anesthetics has extended its indication still more. The causes of accidents lie mostly in ignorance ofthe pharmacology of local anesthetics and their adjuvants, in faulty technical performance of the nerve blockade and last but not least in inadequate knowledge of the therapy, of the side effects and complications. The various complications of regional anesthesia are reported on and the necessary therapy dealt with.

Management of potentially fatal alcohol intoxication.

Severely alcohol intoxicated patients pass through all stages of anesthesia according to the Guedel classification. Additional illnesses or injuries might be present, however. These require careful investigation. Blood alcohol levels are no criterion for the degree of intoxication. The treatment varies and is based on clinical symptoms. In our series of more than 100 alcohol intoxicated patients the treatment generally consisted o Apomorphine, unless unconsciousness was present, and peripheral vasopressors, if necessary. Occasionally endotracheal intubation was required. On gastric aspiration via nasogastric tube only minimal amounts of alcohol could be recovered. With correct diagnosis and effective treatment the cure rate of acute alcohol intoxication should be as high as that of other intoxications.
