Comparative Study
Neuraxial anaesthesia techniques and postoperative outcomes among joint arthroplasty patients: is spinal anaesthesia the best option?
Neuraxial anaesthesia is frequently used for lower limb arthroplasty but it is unclear whether benefits vary among patients receiving different subtypes of neuraxial anaesthesia. We evaluated whether differences in risk for adverse postoperative outcomes exist between patients receiving combined spinal and epidural (CSE), epidural, or spinal anaesthesia. ⋯ We identified clear differences in risk for certain postoperative events by subtype of neuraxial anaesthesia, suggesting that spinal anaesthesia is associated with the most favourable outcomes profile.

Observational Study
Cancelled operations: a 7-day cohort study of planned adult inpatient surgery in 245 UK National Health Service hospitals.
Cancellation of planned surgery impacts substantially on patients and health systems. This study describes the incidence and reasons for cancellation of inpatient surgery in the UK NHS. ⋯ A significant proportion of patients presenting for surgery have experienced a previous cancellation for the same procedure. Cancer surgery is relatively protected, but bed capacity, including postoperative critical care requirements, are significant risk factors for previous cancellations.

Observational Study
Validity and reliability of an objective structured assessment tool for performance of ultrasound-guided regional anaesthesia.
We examined the validity and reliability of the previously developed criterion-referenced assessment checklist (AC) and global rating scale (GRS) to assess performance in ultrasound-guided regional anaesthesia (UGRA). ⋯ Both assessments differentiated between individuals who had performed fewer (≤30) and many (>100) blocks in the preceding year, supporting construct validity. It also established concurrent validity and overall reliability. We recommend that both tools can be used in UGRA assessment.

Gaps in our understanding of genetic susceptibility to malignant hyperthermia (MH) limit the application and interpretation of genetic diagnosis of the condition. Our aim was to define the prevalence and role of variants in the three genes implicated in MH susceptibility in the largest comprehensively phenotyped MH cohort worldwide. ⋯ Our data provide current estimates of the role of variants in RYR1, CACNA1S, and STAC3 in susceptibility to MH in a predominantly white European population.

Multicenter Study
Intraoperative ventilation settings and their associations with postoperative pulmonary complications in obese patients.
There is limited information concerning the current practice of intraoperative mechanical ventilation in obese patients, and the optimal ventilator settings for these patients are debated. We investigated intraoperative ventilation parameters and their associations with the development of postoperative pulmonary complications (PPCs) in obese patients. ⋯ NCT01601223.
