Randomized Controlled Trial Comparative Study Clinical Trial[The use of water to seal facial mask for non invasive ventilation reduces the incidence of pressure ulcers].
To demostrate that the use of water to seal facial mask for non invasive ventilation (NIV) reduces the incidence of facial pressure ulcers. ⋯ The use of water to seal facial mask during invasive non ventilation dealays the appearance of facial ulcers. More studies are needed to demostrate significant reduction in the incidence of ulcers.

Randomized Controlled Trial Comparative Study Clinical Trial[Endotracheal aspiration: respirator vs. manual resuscitation as method for hyperoxygenation and hyperinflation].
Endotracheal aspiration protocols (EAT) include hyperoxygenation and hyperinflation to minimize the negative effects of the technique. No conclusive studies have determined the most effective hyperoxygenation and hyperinflation method. This study had two aims: to compare the effects on patient oxygenation and hemodynamics during endotracheal aspiration of secretions using, respectively, a respirator or manual resuscitator as the hyperoxygenation and hyperinflation method. ⋯ Analysis of the effectiveness of the manual resuscitator (the second aim) under the conditions established yielded a mean FIO2 of 0.86 and a mean tidal volume of 153% in relation to baseline tidal volume. Both methods of hyperoxygenation and hyperinflation prevent hypoxia and maintain hemodynamic stability in patients without producing lung damage. The effectiveness of the manual resuscitator for administering high oxygen concentration and large volumes was confirmed.

Randomized Controlled Trial Comparative Study Clinical Trial[Nursing evaluation of the effect of the type of sedation on the degree of anxiety in patients undergoing cardiac surgery].
The objective of this work is to identify the degree of preoperatory anxiety which patients who must undergo cardiac surgery present, and evaluate the influence of sedation with Propofol or Midazolam in the appearance of anxiety in the immediate and late postoperatory. The study population was formed by 22 patients, being appointed at random to receive Propofol or Midazolam in infusions. ⋯ The patients who were sedated with propofol showed a level of postoperatory anxiety significatively lower than those patients who were treated with midazolam (p < 0.05). To conclude, we believe that the type of sedative used has a significant influence in the development of post-operatory anxiety.
