[Changes in the water-electrolyte and protein balance of the body in acute gastrointestinal ulcerative hemorrhage]. / Promeni na vodno-elektrolitniia i beltuchniia balans na organizma pri ostrata gastrointestinalna iazvena khemoragiia.

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.

[The potentials and limits of thoracic epidural anesthesia in abdominal surgery]. / Vuzmozhnosti i granitsi na torakalnata epiduralna anesteziia v koremnata khirurgiia.

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. The mean duration of the operations was 111.77 min., the preoperative preparation and performance of anesthesia--63 minutes, total 175 minutes. Application of TEA was decided taking into consideration the patient state, the type of operation the alternative for applying general intubation anesthesia, the course of anesthesia and the postoperative analgesia. The hemodynamic changes especially in cardiac patients, other complications and causes of inadequate effect of TEA in 12 cases not included in this report are discussed. As a rule, appendicectomies and inguinal herniotomies were not included also in this report.

[2 cases from the practice of intensive treatment]. / Dva sluchaia ot praktikata na intenzivnoto lechenie.

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.

[Technic for cannulating the great lymph duct in dogs]. / Tekhnika za kaniulirane na glavniia limfen protok u kucheta

The authors described in details the technique for cannulation of the terminal part of the main lymph ductus in dogs. They shared their experience in operating 23 dogs. The authors described the approach to ductus thoracicus, cervical region and most frequent difficulties connected with its finding and preparation. All encountered anatomic variants of the chest ductus were presented. The most critical moment of the operation--introduction of the cannula in the ductus was described in details and the authors proposed some technical methods enhancing quicker and easier cannulation.
