Observational Study
Pain assessment in the postanaesthesia care unit using pupillometry: A cross-sectional study after standard anaesthetic care.
Patients assess their own pain with a numerical rating scale (NRS). In the postanaesthesia care unit (PACU), NRS helps to determine and monitor analgesic administration, but is useless in patients who are unable to communicate. In non-PACU patients, acute pain increases pupillary diameter and pupillary light reflex amplitude (PLRA), the difference between pupillary diameter before and after light stimulation. ⋯ Acute postoperative pain is not associated with pupillary diameter or PLRA. Further research is required to develop tools to assess pain in the PACU.

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.

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.
