Tracheal intubation in coronavirus disease 2019 (COVID-19) patients creates a risk to physiologically compromised patients and to attending healthcare providers. Clinical information on airway management and expert recommendations in these patients are urgently needed. By analysing a two-centre retrospective observational case series from Wuhan,

We assessed patients after their return home following gynaecological surgery, using a daily electronic diary. Thirty-two females aged 27-77 years took part. After a hospital stay of 1-6 days (mean 2.3), they were given a pen-based electronic diary and asked to record symptoms and other data over one month. They also completed a questionnaire at the end of the study. Substantial effects on quality and duration of sleep, pain during both the night and day, interference with daily activities, energy, and ability to concentrate were recorded, mostly during the first week of treatment. Symptoms reported in the final questionnaire correlated significantly with diary data. Most patients found the electronic diary easy to use, and none found it difficult. Daily electronic diaries are an acceptable method of obtaining better information on the extent and duration of symptoms and other difficulties after discharge following surgery. The costs of healthcare provision increase the pressure for efficient use of resources. Reducing the length of hospital stay after surgery is one approach to cost reduction. To properly assess cost effectiveness, information is needed on the degree to which patients are affected by postsurgical problems on their return home, and their speed of recovery.Most of the work in this area has investigated day case surgery, which now accounts for a large proportion of surgical procedures. In Scotland, for example, about 60% of elective surgery is carried out on a day basis [1]. Some studies have investigated the immediate postoperative recovery period using functional measures (ability to drink, void urine, or walk), symptom measures (pain, nausea) or cognitive testing [2][3][4][5]. Others have used questionnaires to assess symptoms and their impact, as well as overall satisfaction, after return home. Studies considering several time-points after discharge show that a substantial proportion of patients have at least moderate pain sufficient to interfere with daily activities, after their return home [4,6,7]. As well as pain, the after effects of surgery may include cognitive impairments. Thus Tzabar et al.[8] used the Cognitive Failures Scale over a 3-day period after day case surgery, and found more failures in patients who had received a general anaesthetic compared to those given only a local anaesthetic. 1101Work on patients undergoing surgery as in-patients has mostly focused on the recovery period before discharge [9][10][11]. Myles et al.[4] administered a Quality of Recovery Scale to patients daily for 6 days then weekly for up to 6 weeks after minor or major surgery. The scale assessed wellbeing, specific functions, symptoms, and need for support. Questionnaires were administered by telephone after discharge, but it is not clear from the report how long these patients stayed in hospital. Substantially greater effects were recorded after major surgery, as expected, with scores returning to baseline after about one week. Other studies have used questionnaires to assess patient satisfa...

Over the last decade, there has been a heightened awareness and an increase in the amount of literature being published on recognition and prediction of the difficult airway. During the preoperative evaluation of the airway, a thorough history and physical specifically related to the airway should be performed. Various measurements of anatomic features and noninvasive clinical tests can be performed to enhance this assessment. In this study we correlated the Mallampati modified score and several other indexes with the laryngoscopic view to identify anatomical and clinical risk factors related to the difficult airway. We prospectively collected data on 1956 consecutive patients scheduled to receive general anesthesia requiring endotracheal intubation for elective surgery. The Mallampati classification versus the Cormack-Lehane (C-L) linear correlation index was 0.904. A Mallampati Class 3 correlated with a C-L Grade 2 (0.94), whereas a Mallampati Class 4 correlated with a C-L Grade 3 (0.85) and a C-L Grade 4 (0.80). Operator evaluation, performed by a simplified tracheal intubation difficulty scale, showed a linear correlation of 0.96 compared with the C-L groups. Although there is a correlation between oropharyngeal volume and difficult intubation, the Mallampati score by itself is insufficient for predicting difficult endotracheal intubation.
