Case Reports[Successful resuscitation of a hypothermic patient with extracorporeal circulation--a case report].
A case of cardiopulmonary arrest due to accidental hypothermia and its successful therapy is described. A 46-year-old man with deep accidental hypothermia (25.3 degrees C esophageal) was found outside showing respiratory and cardiac arrest. Resuscitation was immediately started and continuously performed during the transport to the University Hospital of Rostock, where a treatment with extracorporeal circulation was possible. ⋯ After seven days of intensive therapy, he recovered completely and could be transferred from the intensive care unit to the department of psychiatry without neurological deficits showing only healing of frostbite of the feet. Based on this case report, the use of extracorporeal circulation for adequate rewarming in combination with cardiopulmonary resuscitation is described. Compared to other therapeutic measures such as peritoneal dialysis or veno-venous haemofiltration treatment with extracorporeal circulation is the method of choice.

Patient-controlled analgesia (PCA) is a well-accepted technique in postoperative pain management. We used PCA in three different protocols to find the optimum application form. Our study compared 100 patients with radical prostatectomy or transperitoneal tumor nephrectomy in three groups using piritramide. ⋯ Although the dosage of piritramide was not different in the three groups, we recommend the protocol of group 3 because of the lower refusal of bolus application. Therefore, this seems to be the best patient-adapted application form. Even though respiratory complications in the group 3 scheme are not expected, monitoring of respiration and vigilance are recommended.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of neuromuscular blockade by mivacurium and atracurium].
The aim of our randomized controlled study was to compare the neuromuscular characteristics of mivacurium and atracurium by evaluating the intubation conditions, intubation times, onset times and the duration of action of these two muscle relaxants using two different dosing principles. Forty-eight patients were included in this study. All patients were premedicated orally with 0.2 mg/kg diazepam. ⋯ The patients of group 3 (n = 12) were intubated with 0.46 mg/kg atracurium (2 x ED95) and the patients of group 4 (n = 12) received a priming dose of 0.046 mg/kg atracurium (20% of ED95) and an intubation dose of 0.23 mg/kg atracurium (ED95) four minutes later. The patients were intubated under normocapnic conditions and following stabilisation of the palmar skin temperature after a 90% neuromuscular block (T1) had occurred. The intubation conditions were measured semiquantitatively using an intubation score.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study[Plasma catecholamine level and clinical parameters--quality criteria for premedication in childhood].
Stress hormones noradrenaline and adrenaline were measured in plasma before and after premedication to objectivate the anxiolytic potency of different premedication methods in children. In addition indirect signs of sympathoadrenergic activity (heart rate and blood pressure) as well as children's behavior and reaction to face mask were documented. Each group consisted of 16 children (aged 3 to 15 years). ⋯ After mask exposition in all groups noradrenaline and adrenaline levels increased with the exception of adrenaline in the midazolam-group, where the levels remained low. Mask acceptance and anxiolysis were better in the midazolam-group than in other groups. Reduction in heart rate and blood pressure, catecholamines in plasma, anxiolysis and a high mask acceptance indicate that intravenous administration of midazolam is very effective in premedicating children.

Case Reports[Severe pulmonary complications following venous air embolism in neurosurgical operations in sitting position--2 case reports].
The occurrence of air embolism during neurosurgical operations in sitting position is described in two cases. Besides the Doppler ultrasound evidence, relevant effects on the cardiopulmonary situation during surgery were observed, which in one case forced an early end of the operation. ⋯ In severe intraoperative cardiopulmonary complications in connection with venous air embolism, the existence of pulmonary oedema should be assumed. Confirmation of the diagnosis and the correct therapy depend upon frequent postoperative chest X-rays.
