Review[Perioperative EEG monitoring: studies of the electrophysiological arousal mechanism].
Electroencephalogram recordings have been advocated for assessment of changes in cerebral function during anaesthesia. Controversy exists on the specificity of EEG parameters indicating depth of anaesthesia, because cortical electrical activity is modulated not only by drugs but also by a variety of exogenous and endogenous stimuli. In clinical practice, EEG measures often fail to accurately predict anaesthetic depth since the effects of nociceptive stimulation on the EEG are still not well defined. ⋯ The occurrence of slow EEG wave patterns may be related to functional blockade of the ascending activating system of the brain stem. In contrast, slowing of the EEG is comparable to EEG changes seen with increasing concentrations of anaesthetics. This indicates the difficulty to discriminate arousal phenomena from drug effects using EEG monitoring alone.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports[Capnothorax and subcutaneous emphysema in attempted laparoscopic suture of duodenal ulcer].
A 72-year old lady suffering from coronary heart disease was admitted with acute abdominal pain. Laparoscopy was performed and revealed perforation of a duodenal ulcer. The surgeon decided to suture the perforation via laparoscope. ⋯ The further hospital stay was uneventful. The possible causes for the increasing hypercapnia are discussed. We suggest close monitoring of patients during laparoscopy including capnometry and the anaesthesist should be aware of rare complications.

[Anesthesia in acute respiratory tract obstructions caused by high degree laryngeal and tracheobronchial stenoses].
Stenotic process of the laryngeal and/or tracheobronchial system may lead to dyspnoea which can become life threatening. ⋯ The SHFJV technique presents the possibility to ventilate the patients continuously for surgical procedures even with massive stenosis of the respiratory tract. The application of SHFJV via the jet laryngoscope not only enables the anaesthesist to ventilate this group of patients but also helps the surgeon and therefore results in more safety for the patient.
