Randomized Controlled TrialAllopurinol attenuates postoperative pain and modulates the purinergic system in patients undergoing abdominal hysterectomy: a randomized controlled trial.
Allopurinol is a potent inhibitor of the enzyme xanthine oxidase used primarily in the treatment of hyperuricemia and gout. The aim of this study was to compare the analgesic efficacy of preanesthetic allopurinol versus placebo on postoperative pain and anxiety in patients undergoing abdominal hysterectomy. ⋯ This study showed a short-term benefit of the use of allopurinol as a preanesthetic medication since it was related to a reduction on pain scores 2 h after surgery. The purinergic system is a potential target for new analgesic drugs. New studies investigating more selective purine derivatives in the management of pain should be performed.

ReviewOxygen therapy for critically Ill and post-operative patients.
Nearly all patients receiving treatment in a peri-operative or intensive care setting receive supplemental oxygen therapy. It is biologically plausible that the dose of oxygen used might affect important patient outcomes. Most peri-operative research has focussed on oxygen regimens that target higher than normal blood oxygen levels. ⋯ Some data suggest that conservative oxygen therapy might be preferred for patients with hypoxic ischaemic encephalopathy. However, unless oxygen supplies are constrained, routinely aggressively down-titrating oxygen in either the peri-operative or intensive care setting is not necessary based on available data. Targeting higher than normal levels of oxygen might reduce surgical site infections in the perioperative setting and/or improve outcomes for intensive care patients with sepsis but further research is required and available data are not sufficiently strong to warrant routine implementation of such oxygen strategies.

The short-term effect of COVID-19 pandemic on disability, pain intensity, psychological status, and exercise habits in patients with chronic pain.
The coronavirus disease 2019 (COVID-19) pandemic has affected the lives of people worldwide. The first declaration of a state of emergency in Japan, based on the Act on Special Measures for the Prevention and Control of the Novel Coronavirus, was issued from 16 April 2020 to 14 May 2020 to reduce person-to-person contact. Restrictions on going out, participating in community activities, and visiting hospitals were in place. This study investigates the short-term effects of the COVID-19 pandemic on patients with chronic pain. ⋯ The effects of the COVID-19 pandemic on patients with chronic pain were not apparent in the short-term. Clinical trail registration: UMIN000043174.

A two-handed airway maneuver of mandibular advancement and mouth opening in the neutral neck position for immobilization of the cervical spine.
Immobilization of the cervical spine after trauma is recommended as standard care to prevent secondary injury. We tested the hypothesis that a two-handed airway maneuver, consisting of mandibular advancement and mouth opening in the neutral neck position, would minimize changes in the angle of the cervical vertebrae at the C0/4 level and tidal volume in non-obese patients under anesthesia with neuromuscular blockade. ⋯ Our study suggests that a two-handed airway maneuver of mandibular advancement and mouth opening in the neutral neck position results in only slight change in the cervical vertebral angle at the C0/4 level in non-obese patients under general anesthesia with neuromuscular blockade.
