Case ReportsIntracranial subdural haematoma--a rare complication following spinal anaesthesia.
We present a rare case with postspinal headache resulting in an intracranial subdural haematoma. After 5 days of persistant headache the condition was recognized and diagnosed on a computerized tomography-scan (CT) of the skull. The patient was operated with evacuation of the haematoma 2 weeks after the spinal anaesthesia and recovered completely.

Continuous end-tidal carbon dioxide monitoring during normofrequent jet-ventilation.
Continuous end-tidal carbon dioxide (ETCO2) monitoring during normofrequent jet-ventilation (NFJV) has not previously been successful and no correspondence between ETCO2 and arterial carbon dioxide (PaCO2) demonstrated. ⋯ A valuable method of continuous ETCO2 monitoring during NFJV is presented.

Pre-eclampsia: the effect of intravenous fluid preload on atrial natriuretic peptide secretion during caesarean section under spinal anaesthesia.
The haemodynamic effect of volume load at elective Caesarean delivery may be modulated by atrial natriuretic peptide (ANP) especially in pre-eclamptic women in whom basal ANP levels are increased. ⋯ These findings concur with the theory that atrial stretch is a stimulus for ANP release. An exaggerated release of ANP in response to volume loading may aid in the adaptation of maternal circulation to volume load at elective Caesarean delivery in pre-eclamptic women.

Effects of halothane, isoflurane and sevoflurane on ischemia-reperfusion injury in the perfused liver of fasted rats.
Although intraoperative ischemia-reperfusion of the liver generally occurs under general anesthesia, little is known about the direct effect of anesthetic agents on hepatic injury due to this phenomenon. The effect of volatile anesthetics on ischemia-reperfusion injury was studied using isolated liver perfusion. ⋯ These results indicate that volatile anesthetics may protect the fasted liver from early, neutrophil-independent, ischemia-reperfusion injury by acting during the reperfusion phase.

ReviewAwareness in anaesthesia: incidence, consequences and prevention.
Awareness during anaesthesia is a state of consciousness that is revealed by explicit or implicit memory of intraoperative events. Although large clinical surveys indicate an incidence of explicit awareness of < 0.3% during anaesthesia for general surgery, this adverse effect should be a great concern, because patients may be permanently disabled by the experience of being awake during surgery. ⋯ The anaesthetic depth should be assessed by observation of movement responses, and consequently a minimum of muscle relaxants used. Because the anaesthetic depth can be controlled by determination of endtidal drug concentration, volatile inhaled anaesthesia may be associated with a lower frequency of awareness than other anaesthetic regimens.
