Case Reports
[Bronchial rupture. Diagnosis and therapy of a rare complication of the use of double-lumen tubes].
For anesthesia during thoracic surgery, it is common to use a double-lumen endotracheal tube for one-lung ventilation. Double-lumen tubes protect the bronchial system of the healthy lung from being occluded by blood or pus coming from the operated lung. Therefore, in cases of lung abscess, bronchial hemorrhage, lung cyst, or localized lung infection the use of a double-lumen tube is advisable. ⋯ The intraoperative symptoms of airway leakage are demonstrated, the process of locating and repairing the injury is described. In our case the postoperative course was not complicated; the patient left the hospital 10 days after operation. Causes of bronchial rupture, its therapy, and prophylactic measures are also discussed.

Delayed hypersensitivity to rubber chemicals is well known, but there has been an increasing number of reports of immediate-type hypersensitivity due to latex causing contact urticaria, angioedema, bronchial asthma, and anaphylactic shock in adults. We report a 10-year-old boy who developed anaphylactic shock during surgery due to surgical gloves containing latex. The patient was atopic and had a history of neurodermatitis and localized angioedema on exposure to rubber. ⋯ The circulation and gas exchange stabilized after treatment with oxygen, intravenous fluids, epinephrine, H1 and H2 blockers, aminophylline, and methylprednisolone. A positive skin test and RAST revealed a latex allergy. Latex can cause life-threatening allergic reactions in patients with a history of rubber allergy or frequent exposure to latex products.

A 5-year-old boy with acute lymphatic leukemia in remission developed signs of malignant hyperthermia (MH) during general anesthesia for removal of a central venous access port. The anesthetic procedure for implantation of the port 17 months before had been uneventful despite use of the same triggering agents, halothane and succinylcholine. Meanwhile, the patient had received chemotherapy (COALL-03-85). ⋯ We do not believe the chemotherapy our patient received between the two anesthetics was the cause since about one-half of the patients in the literature had not had chemotherapeutic pretreatment at the time of the MH crisis. We believe that a common genetic predisposition is the most likely link between the two diseases. In any case, patients with leukemias and lymphomas should be monitored very carefully for symptoms of MH.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial
[Optimal dosage strategies in total intravenous anesthesia using propofol and ketamine].
The combination of propofol and ketamine for total intravenous anesthesia was investigated; the intention was to minimize the side effects of each drug by the concomitant application of the other drug. METHODS. Twenty patients scheduled for lower abdominal interventions were divided into two groups. ⋯ The major known side effects of propofol (reduced hemodynamics during induction) and ketamine (psychic disturbances and cardiovascular stimulation) were absent and respiratory function was adequate after the end of surgery. This technique, therefore, can be used in risk patients and under disaster conditions when i.v. access is the only possible route of drug administration. The use of computer-assisted infusion pumps markedly enhances handling and controllability of total i.v. anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
[A comparison of autologous transfusion procedures in hip surgery].
The risks associated with transfusion can be minimized with autologous blood. The efficiency of preoperative deposit, preoperative hemodilution and intra- and postoperative autotransfusion in reducing homologous transfusions has been demonstrated. There seem to be few studies, however, that compared the different methods of autologous transfusion. ⋯ CONCLUSION. Under the conditions studied, preoperative autologous deposit was the most efficient method of autologous transfusion for hip arthroplasty. It should be employed primarily.
