Meta Analysis
Accuracy and Feasibility of Clinically Applied Frailty Instruments before Surgery: A Systematic Review and Meta-analysis.
The Clinical Frailty Scale is the most feasible frailty measure and has the strongest association with mortality and non-favourable discharge.

Randomized Controlled Trial Multicenter Study
Individualized Fluid Management Using the Pleth Variability Index: A Randomized Clinical Trial.
The present trial was designed to assess whether individualized strategies of fluid administration using a noninvasive plethysmographic variability index could reduce the postoperative hospital length of stay and morbidity after intermediate-risk surgery. ⋯ Among intermediate-risk patients having orthopedic surgery with general anesthesia, fluid administration guided by the plethysmographic variability index did not shorten the duration of hospitalization or reduce complications.

Randomized Controlled Trial
Ketamine and Magnesium for Refractory Neuropathic Pain.
Ketamine is often used for the management of refractory chronic pain. There is, however, a paucity of trials exploring its analgesic effect several weeks after intravenous administration or in association with magnesium. The authors hypothesized that ketamine in neuropathic pain may provide pain relief and cognitive-emotional benefit versus placebo and that a combination with magnesium may have an additive effect for 5 weeks. ⋯ The results of this trial in neuropathic pain refuted the hypothesis that ketamine provided pain relief at 5 weeks and cognitive-emotional benefit versus placebo and that a combination with magnesium had any additional analgesic effect.

Multicenter Study Observational Study
Incidence and Classification of Nonroutine Events during Anesthesia Care.
A nonroutine event is any aspect of clinical care perceived by clinicians or trained observers as a deviation from optimal care based on the context of the clinical situation. The authors sought to delineate the incidence and nature of intraoperative nonroutine events during anesthesia care. ⋯ This study describes characteristics of intraoperative nonroutine events in a cohort of cases at three academic hospitals. Nonroutine event-containing cases were commonly associated with patient impact and injury. Thus, nonroutine event monitoring in conjunction with traditional error reporting may enhance our understanding of potential intraoperative failure modes to guide prospective safety interventions.

Randomized Controlled Trial
Magnesium and Bladder Discomfort after Transurethral Resection of Bladder Tumor.
Catheter-related bladder discomfort occurs because of involuntary contractions of the bladder smooth muscle after urinary catheterization. Magnesium is associated with smooth muscle relaxation. This study hypothesized that among patients having transurethral resection of bladder tumor, magnesium will reduce the incidence of postoperative moderate-to-severe catheter-related bladder discomfort. ⋯ Magnesium reduced the incidence of catheter-related bladder discomfort above a moderate grade and increased patient satisfaction among patients having transurethral resection of bladder tumor.
