[Hypothermia during general anesthesia and methods of its prevention].
In the article great attention is paid to prophylaxis of hypothermal disturbances in heat exchange during the process of general anesthesia, it comprises the use of complex methods of protection against hypothermia. It is the authors' opinion that the state of thermal balance should be followed as carefully during general anesthesia as hemostatic indices, since normothermia improved considerably the clinical course of narcosis and postoperative period, as well.

Comparative StudyCardiorespiratory function during thoracic anaesthesia: a comparison of two-lung ventilation and one-lung ventilation with and without PEEP5.
Previous studies have shown that, in patients undergoing thoracic surgery, a relatively high positive end-expiratory pressure (PEEP of 10 cmH2O = PEEP10) has no beneficial effect on oxygenation during one-lung ventilation (OLV). In the present investigation, cardiorespiratory function was examined in 11 patients intubated endobronchially and undergoing thoracotomy. Comparison was made between two-lung ventilation (TLV) and OLV and between zero end-expiratory pressure and PEEP5 during OLV. ⋯ The application of PEEP5 during OLV produced no significant changes in these parameters. The findings in individual patients demonstrated the relative importance of cardiac output in determining oxygen delivery during OLV. A significant negative correlation was found between inspiratory airway pressure and cardiac index during OLV.

The change in end-tidal position (ETP) after suxamethonium-induced paralysis was measured in 15 children during routine general anaesthesia. In all patients the onset of muscle paralysis was associated with an increase in lung volume from ETP. This increase may be the result of paralysis of the expiratory muscles which are active during anaesthesia.
