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.

Despite widespread use of ultrasound imaging to guide needle placement, the incidence of transient and permanent nerve damage as a complication of regional anaesthesia has not changed over the last decade. In view of the controversy surrounding intraneural injection there is a need to understand the structural changes caused by subepineural and subperineural needle penetration. Clinical ultrasound machines do not provide adequate anatomical resolution, and anaesthetists have difficulty judging the precise location of the needle tip relative to the epineurium. ⋯ A regional block needle was inserted into three median nerves. We identified fascicles > 0.4 mm in width using micro-ultrasound. Subepineural needle placement was associated with denting, rotation and elastic deformation of fascicles, whereas subperineural needle insertion split fascicles permanently.
