Randomized Controlled Trial
Calling the patient's own name facilitates recovery from general anaesthesia: a randomised double-blind trial.
People can hear and pay attention to familiar terms such as their own name better than general terms, referred to as the cocktail party effect. We performed a prospective, randomised, double-blind trial to investigate whether calling the patient's name compared with a general term facilitated a patient's response and recovery from general anaesthesia. We enrolled women having breast cancer surgery with general anaesthesia using propofol and remifentanil. ⋯ The mean (SD) time was 337 (154) s in the name group and 404 (170) s in the control group (p = 0.041). The time to i-gel® removal was 385 (152) vs. 454 (173) s (p = 0.036), the time until achieving a bispectral index of 60 was 174 (133) vs. 205 (160) s (p = 0.3), and the length of stay in the postanaesthesia care unit was 43.8 (3.4) vs. 47.3 (7.1) min (p = 0.005), respectively. In conclusion, using the patient's name may be an easy and effective method to facilitate recovery from general anaesthesia.

Management of the difficult airway is an important, but as yet poorly-studied, component of intensive care management. Although there has been a strong emphasis on prediction and intubation of the difficult airway, safe extubation of the patient with a potentially difficult airway has not received the same attention. ⋯ The findings in the section on Intensive Care and Emergency Medicine reinforce the importance of good airway management in the critical care environment and, in particular, the need for appropriate guidelines to improve patient safety. This narrative review focuses on strategies for safe extubation of the trachea for patients with potentially difficult upper airway problems in the intensive care unit.

Randomized Controlled Trial
Microvascular reactivity and endothelial glycocalyx degradation when administering hydroxyethyl starch or crystalloid during off-pump coronary artery bypass graft surgery: a randomised trial.
The infusion of fluids to patients may affect tissue microcirculation and the endothelial glycocalyx. However, the effects of hydroxyethyl starch and crystalloid on endothelial glycocalyx degradation and microvascular reactivity have not been evaluated in detail. We hypothesised that hydroxyethyl starch may cause less endothelial glycocalyx degradation and better microvascular reactivity than that caused by crystalloid. ⋯ Vascular occlusion test parameters, including tissue oxygen saturation, occlusion and recovery slope did not differ significantly between the groups. Peri-operative changes in syndecan-1 were not significantly different between the groups. We conclude that, in patients undergoing off-pump coronary artery bypass graft surgery, compared with crystalloid, the use of hydroxyethyl starch 670/0.75 did not result in significant differences in microvascular reactivity or endothelial glycocalyx degradation.
