Review[Transfusion therapy and volume treatment in elective surgery and traumas].
New light has recently been shed on transfusion therapy. Early recurrence of cancer, ill effects on the immune system and increased incidence of postoperative infections have all been suggested as possible complications of overenthusiastic transfusion therapy. ⋯ With this in mind, blood component therapy, giving erythrocytes and plasma components according to documented need, has been started. The article describes our institution's suggested policy for transfusion therapy and volume treatment in elective and trauma surgery.

Review[Conscious and unconscious awareness during anesthesia--how deep is the patient's sleep?].
A review is given over the aspects of awareness during general anaesthesia. Traditional clinical signs for evaluating depth of anaesthesia can be supplemented by objective methods such as EEG, cerebral function monitor and sensory evoked potentials. ⋯ Awareness can be graded from the obvious form, with recall of intraoperative events, to an unconscious form where the memory can be activated through special psychological techniques. We discuss the possibility of using unconscious perception of auditory signals for positive instructions to patients under anaesthesia.
