Randomized Controlled Trial Multicenter StudySafety and efficacy of oral rehydration therapy until 2 h before surgery: a multicenter randomized controlled trial.
In many countries, patients are generally allowed to have clear fluids until 2-3 h before surgery. In Japan, long preoperative fasting is still common practice. To shorten the preoperative fasting period in Japan, we tested the safety and efficacy of oral rehydration therapy until 2 h before surgery. ⋯ Oral rehydration therapy until 2 h before surgery is safe and feasible in the low-risk Japanese surgical population. Physicians are encouraged to use this practice to maintain the amount of water in the body and electrolytes and to improve the patient's comfort.

Randomized Controlled TrialEffects of sevoflurane and propofol on pulmonary inflammatory responses during lung resection.
Pulmonary inflammatory reactions are affected by one-lung ventilation (OLV) and anesthetic agents. However, the effects of anesthetic agents on pulmonary inflammatory reactions may vary. Our previous investigations suggested that inflammatory reactions were more pronounced in the dependent lung during lung resection under general anesthesia with propofol and remifentanil. Therefore, in the present study we attempted to determine the difference in pulmonary inflammatory reaction using either sevoflurane or propofol in both dependent and nondependent lungs during OLV. ⋯ One-lung ventilation induced inflammatory responses of the bronchial epithelia in the dependent lung and the nondependent lung during lung resection. Moreover, this inflammatory response was significantly suppressed by sevoflurane compared with propofol. Furthermore, the antiinflammatory effect of sevoflurane was more pronounced in the dependent lung than in the nondependent lung during OLV.

Lung injury induced by the pulmonary instillation of povidone-iodine in rats.
Povidone-iodine (polyvinylpyrrolidone iodine, PI), which is commonly used as a pre- and postoperative oral antiseptic, has been reported to cause pneumonia secondary to its pulmonary aspiration. Because no studies have yet investigated the underlying mechanisms of PI-induced pneumonia, we conducted an animal study to analyze the effect of PI on the lung following its pulmonary instillation. ⋯ PI aspiration can cause lung injury, including pulmonary fibrosis.

Apolipoprotein E e4 allele does not increase the risk of early postoperative delirium after major surgery.
A relationship between patients with a genetic predisposition to and those who develop postoperative delirium has not been yet determined. The aim of this study was to determine whether there is an association between apolipoprotein E epsilon 4 allele (APOE4) and delirium after major surgery. ⋯ Apolipoprotein e4 carrier status was not associated with an increased risk for early postoperative delirium. Age, congestive heart failure, and emergency surgery were independent risk factors for the development of delirium after major surgery.
