Short courses of mechanical ventilation with high-O2 levels in elderly rat lungs.
To evaluate the effects of mechanical ventilation (MV) of high-oxygen concentration in pulmonary dysfunction in adult and elderly rats. ⋯ A higher fraction of inspired oxygen in short courses of mechanical ventilation ameliorates the parameters studied in elderly lungs.

Randomized Controlled TrialL-alanyl-glutamine pretreatment attenuates acute inflammatory response in children submitted to palatoplasty.
To evaluate the effects of L-alanyl-glutamine (L-Ala-Gln) pretreatment on oxidative stress, glycemic control and inflammatory response in children submitted to palatoplasty. ⋯ Pretreatment with L-Ala-Gln in children submitted to palatoplasty attenuates the inflammatory response in early post-operative period and promoted a better glycemic control.

Randomized Controlled Trial Comparative StudyMetabolic and oxidative effects of sevoflurane and propofol in children undergoing surgery for congenital heart disease.
To evaluate the metabolic and oxidative effects of sevoflurane and propofol in children undergoing surgery for correction of congenital heart disease. ⋯ Anesthetic techniques investigated in this study showed a similar pattern, with no increase in metabolic substrates and oxidative stress during surgical correction of congenital heart defects in non-cyanotic children.

Comparative StudyEnergy expenditure in critically ill surgical patients. Comparative analysis of predictive equation and indirect calorimetry.
The aim of this investigation was to compare the resting energy expenditure (REE) calculated by the Harris-Benedict equation (REE HB) with the REE measured by indirect calorimetry (REE IC) in critically ill surgical patients under mechanical ventilation. ⋯ These findings suggest that REE IC seems to be more appropriate than REE HB for accurate measurement of REE in critically ill surgical patients under mechanical ventilation.

Influence of metoclopramide on abdominal wall healing in rats subjected to colonic anastomosis in the presence of peritoneal sepsis induced.
To evaluate the effects of metoclopramide on abdominal wall healing in rats in the presence of sepsis. ⋯ animals treated with metoclopramide had a higher resistance of the abdominal wall on the 3rd postoperative day.
