Randomized Controlled TrialCan electromyographic arousal be detected visually on the Datex-Ohmeda S/5™ anesthesia monitor?
Electroencephalogram (EEG)-based depth of anaesthesia monitoring is susceptible to contaminating electromyographic (EMG) activity. Many authorities have suggested that anaesthesiologists using these monitors should interpret the raw EEG waveform seen on the anaesthesia monitor. ⋯ In contrast to many EEG phenomena, EMG activity cannot be accurately detected visually from the raw EEG on the anaesthesia monitor. Further development in the quality of the anaesthesia monitors is warranted.

ReviewNew hypothesis of chronic back pain: low pH promotes nerve ingrowth into damaged intervertebral disks.
The pathogenesis of low back pain is still elusive. Here, we proposed a new hypothesis that low pH is a possible cause of the development and progression of low back pain. ⋯ The inflammation response, evoked by the dorsal root ganglia, changes the delicate nutrient balance in the nucleus, resulting in a vicious cycle and leading to choronic back pain. Our hypothesis may explain many of the available clinical and experimental data on low back pain, thus it may help elucidate the pathogenesis of low back pain and improve clinical management.

Randomized Controlled TrialThe duration of fibre-optic intubation is increased by cricoid pressure. A randomised double-blind study.
In some categories of patients, a rapid sequence induction using a fibre-optic method may be indicated. The aim of the present study was to examine the effect of cricoid pressure (CP) on the duration of fibre-optic intubation. The hypothesis was that CP would prolong the intubation time. ⋯ The study showed that CP prolongs the duration of fibre-optic intubation in patients with Mallampati grades 1-2.

Extracorporeal membrane oxygenation in adult patients with severe acute respiratory failure.
A group of patients with severe acute respiratory distress syndrome (ARDS) is resistant to advanced respiratory therapy. In these patients, extracorporeal membrane oxygenation (ECMO) can be used as a rescue therapy. This study presents 14 years of experience from a Scandinavian ECMO centre. The aim of the study is to present outcome results and to investigate whether or not simplified acute physiology score II (SAPS-II), sequential organ failure assessment (SOFA) and/or Murray scores can be used to predict patients' outcome. ⋯ Patients with severe ARDS have a favourable outcome when treated with ECMO and when an ECMO retrieval team establishes the ECMO treatment at the referring hospital. SAPS-II, SOFA and Murray scores predicted the outcome.
