Randomized Controlled Trial
Omitting fentanyl reduces nausea and vomiting, without increasing pain, after sevoflurane for day surgery.
Despite advantages of induction and maintenance of anaesthesia with sevoflurane, postoperative nausea and vomiting occurs frequently. Fentanyl is a commonly used supplement that may contribute to this, although it may also improve analgesia. ⋯ As fentanyl exacerbated postoperative nausea and vomiting without an improvement in postoperative pain and also had adverse cardiorespiratory effects, it appears to be an unnecessary and possibly detrimental supplement to sevoflurane in day surgery.

Despite evidence of their prognostic power for non-surgical patients, the value of perioperative natriuretic peptides and cardiac troponins as markers of cardiac events is incompletely defined. This study sought to examine whether perioperative N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponin T (cTnT) levels could be used for the prediction of in-hospital cardiac events in elderly patients undergoing elective coronary artery bypass grafting. ⋯ In elderly patients undergoing elective coronary artery bypass grafting surgery, high values of NT-proBNP and cTnT measured 24 h after the end of surgery were independently associated with in-hospital cardiac events.

Rheumatoid arthritis is a lifelong systemic disease that can affect any joint with a synovium. Managing intubation in patients with rheumatoid disease is a special challenge in these patients especially if specific joints, which play an important role during intubation, are affected. We aimed to investigate if there was a correlation between the activity and duration of the disease and the commonly used predictors of difficult intubation in rheumatoid arthritis. ⋯ Tests of disease activity and the duration of the disease were not found to be correlated with the predictors of difficult intubation in this study. Thus, performing the predictive tests for difficult intubation especially in patients with very low scores or short disease is recommended.

Clinical Trial
Variation of bispectral index monitoring in paediatric patients undergoing propofol-remifentanil anaesthesia.
The technology of bispectral index monitoring is based on an algorithm developed from adults. This study was conducted to investigate the difference in bispectral index monitoring between paediatric and adult patients under intravenous anaesthesia. ⋯ At loss of consciousness and regaining of consciousness, the bispectral index values of younger children group are significantly higher than those of adults. At the same stable concentrations of propofol, the bispectral index values are significantly different between children and adults. This study suggests that there is deviation when the adult algorithm of bispectral index monitoring is applied in paediatric patients under intravenous anaesthesia.

The efficacy of administering a perfluorochemical-based oxygen therapeutic such as perflubron emulsion (Oxygen) prior to ischaemia is currently unknown, although there is evidence for potential beneficial effects for the perioperative treatment in cardiac risk patients. This experimental study investigated the efficacy of perflubron emulsion in preventing reperfusion injury and myocardial infarction size after coronary ischaemia and reperfusion. The perflubron emulsion was given either in a prophylactic manner, prior to induction of myocardial ischaemia, or as a therapeutic agent given during ischaemia. ⋯ Although administration of perflubron emulsion did not reduce infarct size, areas of impaired perfusion were significantly mitigated when perflubron emulsion was administered prior to coronary occlusion. However, a high oxygen concentration may provoke DNA strand breaks during reperfusion after ischaemia. Further studies must clarify whether enhanced oxidative stress outweighs the advantage of improved areas of impaired perfusion following perflubron emulsion.
