[Changes in the water-electrolyte and protein balance of the body in acute gastrointestinal ulcerative hemorrhage].

The authors studied 127 patients, divided into 4 groups, relating to the haemorrhage stage in accordance with the classification of Lutsevich. It has been established that there exist changes in the hydroelectrolytic and protein balance of the patients having acute gastrointestinal ulcerative haemorrhage.

[2 cases from the practice of intensive treatment].

Two cases from the intensive treatment practice are presented: Case I--a 43-year-old woman drawn out from a state of clinical death during chronic dialysis for chronic renal failure with importunate ultrafiltration to combat the severe pulmonary edema, which led to hypoxia and cardiac arrest with functionally affected hemodynamic parameters (central venous pressure), because of centrally placed a/v fistula. Case II--a 46-year-old woman with severe drug disease and extremely critical hypotonic hyperhydration and anasarca, treated also with ultrafiltration, enhanced sodium influx and intensive application of diuretics; for 24 hours a negative fluid balance was achieved (71191 ml) until finally a relative fluid-electrolyte equilibrium was reached.

[The potentials and limits of thoracic epidural anesthesia in abdominal surgery].

A general clinical assessment was made of the possibilities and limits of thoracic epidural anesthesia (TEA) in 132 abdominal operations. The technique applied for preparation, the performance and induction in anesthesia, the intraoperative observation and the postoperative analgesia are described. The patients were evaluated according to ADA for risk factors and the accompanying diseases, the diagnoses by groups and the operations performed on the bile ducts, the small and large intestines, the liver, the retroperitoneal organs, combined operations, interventions on the anterior abdominal wall etc were presented.
