Observational StudyAcute alcohol intoxication and bispectral index monitoring.
Bispectral index (BIS) monitoring is commonly used to decrease the risk of awareness during anaesthesia. We aimed to determine the relationship between blood alcohol concentration and brain function (as measured by BIS) in healthy adults. ⋯ In healthy young adults, we found a moderate correlation between venous blood alcohol concentration and BIS. This suggests that acute alcohol consumption can decrease BIS. This information may be relevant when providing anaesthesia to intoxicated patients who require urgent or time-critical surgery, although certain limitations of this study should be kept in mind.

Review[Intraoperative neuroprotection - influence of the anaesthesiological management].
Perioperative neurofunctional disorders may become clinically apparent as e.g. perioperative stroke (POS) or postoperative cognitive deficit (POCD). Newly diagnosed neuro-functional disorders are associated with worsening of postoperative outcome. Focus of this review article is on the possibilities of the intraoperative anaesthesiological management to favourably influence incidence and severity of neurological complications and to improve postoperative outcome.

Pulmonary Impedance and Pulmonary Doppler Trace in the Perioperative Period.
Pulmonary hypertension and associated vascular changes may frequently accompany left-sided heart disease in the adult cardiac surgical population. Perioperative assessment of right ventricular function using echocardiography is well established. In general, understanding the constraints upon which the right ventricle must work is mostly limited to invasive monitoring consisting of pulmonary artery pressures, cardiac output, and pulmonary vascular resistance. ⋯ The measurement of acceleration time, the time from onset to peak flow velocity is an indicator of constraint to ejection; shortened times have been associated with increased pulmonary vascular resistance and pressure. Understanding the changes in the pulmonary arterial system in disease and the physics of the hemodynamic alterations are essential in interpreting pulmonary artery Doppler data. Analyzing pulmonary artery Doppler flow signals may assist in the evaluation of right ventricular function in patients with pulmonary vascular disease.

To compare knee confidence and kinesiophobia (fear of re-injury) in those with and without knee osteoarthritis following anterior cruciate ligament reconstruction, and determine whether poorer knee confidence is associated with greater kinesiophobia, worse knee-related symptoms, and functional impairments in those with knee osteoarthritis. ⋯ Psychological impairments are evident in people with knee osteoarthritis following anterior cruciate ligament reconstruction, compared to those without. Future studies should further investigate the psychological impairments associated with knee osteoarthritis after anterior cruciate ligament reconstruction.
