[Does insufflation of the abdomen in laparoscopic surgery affect acid-base and ventilatory parameters?].

The cardiopulmonary and metabolic changes experienced by patients undergoing laparoscopic cholecystectomy with CO2 pneumoperitoneum are not well understood. The purpose of this study is to determine changes of basal parameters during laparoscopy and evaluate their prognostic value. One hundred patients (26 obese, 39 older than 60 years, 7 obese and older than 60) undergoing laparoscopic cholecystectomy for uncomplicated cholecystolithiasis were included in the study.

[Changes in acid-base equilibrium, ventilation parameters and immunologic reactions in thoracoscopic operations].

In the thoracoscopic operations it is usually necessary to deflate completely the ipsilateral lung. The aim of this study was to determine changes of blood gases and alterations of immune response mediators during thoracoscopic surgery with one-lung ventilation OLV. In the study 38 patients were included undergoing thoracoscopic or video-assisted thoracic surgery.

[Parenteral nutrition in multiple injuries. III].

One of the main features of parenteral nutrition in patients with multiple injuries remains the slow administration of different substances and the adherence to "anti-insulin provisions" which are usually called for during the first week after the injury. The recommended ratio of amino acids with branched carbon chains for patients with multiple injuries (i. e.
