Hospital administrators often seek to increase operating room (OR) elective caseload. Previous studies from Iowa demonstrated that surgical growth is mostly from low-caseload surgeons (ie, ≤2 cases per week). We repeated that study using data from Florida, a much more populous state, to confirm the generalizability of the findings. ⋯ Surgical growth in elective surgery at Florida hospitals accrued mostly from the increased activity of low-caseload surgeons averaging ≤2.0 cases per week during the preceding year, confirming the generalizability of the previous Iowa study. If growth in caseload is desired, surgical governance committees should ensure that low-caseload surgeons have access to the OR schedule.

Randomized Controlled Trial
Tracheal intubation using intubating laryngeal tube iLTS-D™ and LMA Fastrach™ in 99 adult patients: A prospective multicentric randomised non-inferiority study.
This study aimed to investigate the overall success of tracheal intubation using the intubating Laryngeal Tube Suction-Disposable (iLTS-D™, VBM, Sulz a. N., Germany) compared to the Laryngeal Mask Airway (LMA) Fastrach™ (Teleflex, Athlone, Ireland). We hypothesised that the iLTS-D™ would be non-inferior to the LMA Fastrach™ for tracheal intubation and ventilation. ⋯ Although both supraglottic devices provided the same effective ventilation rate, the LMA Fastrach™ was superior to the iLTS-D™ as a conduit for intubation in 99 adult patients without a known difficult intubation. These preliminary results need to be confirmed in studies that include a larger population.

Randomized Controlled Trial
The effect of delirium preventive measures on the occurrence of postoperative cognitive dysfunction in older adults undergoing cardiovascular surgery. The DelPOCD randomised controlled trial.
This trial examines the effect of delirium preventive measures on the incidence of postoperative cognitive dysfunction in older adults. ⋯ These findings suggest that an intervention combining specific measures extracted from established postoperative delirium prevention programs did not reduce the rate of postoperative cognitive dysfunction in older adults.

Multicenter Study Observational Study
Comparison of neuromuscular block measured by compressomyography at the upper arm and electromyography at the adductor pollicis muscle in obese and non-obese patients: An observational study.
Quantitative neuromuscular monitoring is traditionally evaluated at the adductor pollicis muscle. By contrast, the TOF-Cuff compressomyograph evaluates neuromuscular block (NMB) at the upper arm. However, compressomyography has not been fully validated against other monitoring entities. This study evaluates the agreement between NMB measured by compressomyography at the upper arm and electromyography at the adductor pollicis muscle during various levels of neuromuscular block in patients with and without obesity. ⋯ There is variable disagreement between the level of NMB measured at the upper arm by compressomyography and at the adductor pollicis muscle measured by electromyography, throughout the various stages of NMB in obese and non-obese patients. Recovery of NMB on compressomyography preceded recovery on electromyography, which may have consequences for reversal and extubation decisions in clinical practice.

Randomized Controlled Trial
Acoustic lens improves superficial in-plane ultrasound-guided procedures - The significance of the beam width artefact.
The three-dimensional shape of the ultrasound beam produces a thicker scan plane than most users assume. Viewed longitudinally, a needle placed lateral to a vessel just outside the central scanning plane can be displayed incorrectly in the ultrasound image as if placed intravascularly. This phenomenon is called the beam width artefact, also known as the elevation or slice thickness artefact. The goal of this study was to demonstrate the potential negative effect of the beam width artefact on the performance of in-plane ultrasound-guided vascular access procedures, and to provide a solution. ⋯ The beam width artefact has a significant effect on the performance of ultrasound-guided needle-based procedures. The efficacy of in-plane superficial vascular access procedures can be enhanced by narrowing the imaging plane using an acoustic lens.
