To assess the ability of field tests of exercise tolerance, such as the 6-minute walk test (6MWT) and incremental shuttle walk test (ISWT), to predict postoperative outcome following intra-abdominal surgery. ⋯ Field tests may be able to predict postoperative outcome; however, further validation is needed. The ISWT appears to be the superior field test. The 6MWT and stair climb test require further validation to assess their predictive ability.

Randomized Controlled Trial Comparative Study
A comparison of 3 ventilation strategies in children younger than 1 year using a Proseal laryngeal mask airway: a randomized controlled trial.
To determine quantitative differences in several routinely measured ventilation parameters using a standardized anesthetic technique and 3 different ventilation modalities in patients younger than 1 year with a ProSeal laryngeal mask airway (PLMA). ⋯ All 3 modes of ventilation using a PLMA were safe in children younger than 1 year. Although we did not observe a statistically significant increase in etco2, differences in TV and RR, and the small but significant incidence of apnea may make PSV or PCV more optimal ventilation strategies in children younger than 1 year when using a PLMA.

Observational Study
Risk factors for failed reactivation of a labor epidural for postpartum tubal ligation: a prospective, observational study.
To determine specific risk factors that increase the failure rate of labor epidurals reactivated for use as a surgical block for postpartum tubal ligation. ⋯ Poor satisfaction score of the epidural during labor and delivery, increasing time from delivery to epidural reactivation for tubal ligation, and the need for top-ups during labor and delivery increase the incidence of reactivation failure. No correlation was found with body mass index or loss of resistance and failure to reactivate.

To describe the perioperative blood conservation strategies and postoperative outcomes in patients who undergo complex spinal surgery for tumor resection and who also refuse blood product transfusion. ⋯ Patients who decline blood product transfusion can successfully undergo major spine tumor resection. Careful patient selection and timely referral for perioperative optimization such that the risk of severe anemia is minimized are important for success.

Observational Study
Continuous ambulatory adductor canal catheters for patients undergoing knee arthroplasty surgery.
To determine after knee arthroplasty surgery the feasibility of discharging patients home on postoperative day 1 with continuous adductor canal blocks. ⋯ Ambulatory adductor canal catheters are a feasible analgesic modality after knee arthroplasty surgery as pain scores remained low and adverse events were minimal.
