Observational Study
Preoperative urine-specific gravity and the incidence of complications after hip fracture surgery: A prospective, observational study.
Mild to moderately severe dehydration is common in the elderly, but its relationship to surgical outcome is unclear. ⋯ Dehydration before surgery nearly quadrupled the number of postoperative complications after hip fracture repair.

Observational Study
Accuracy and precision of commonly used methods for quantifying surgery-induced insulin resistance.
Insulin resistance develops in the perioperative setting and has an adverse influence on postoperative recovery and well-being. ⋯ Despite reasonably good linear correlations, the static tests grossly underestimated the degree of insulin resistance that developed in response to surgery.

Observational Study
Effect of head rotation during surgery in the prone position on regional cerebral oxygen saturation: A prospective controlled study.
Near-infrared spectroscopy (NIRS) has been used to study regional cerebral blood oxygen saturation (rScO2) in patients in the prone position. ⋯ We recommend the neutral head position for prone patients.TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01760369.
