Randomized Controlled Trial Comparative Study Clinical Trial
Effect of combined kinetic therapy and percussion therapy on the resolution of atelectasis in critically ill patients.
Some critically ill patients have difficulty in mobilizing their respiratory secretions. These patients can develop pulmonary atelectasis that may result in hypoxemia. There are some data to show that atelectasis may be prevented by turning a patient from side to side utilizing special beds. ⋯ KT and mechanical P therapy resulted in significantly greater partial or complete resolution of atelectasis as compared with conventional therapy. There was a generalized trend toward statistical significance in the improvement of oxygenation and a reduced need for bronchoscopy in the group receiving KT and P therapy.

Randomized Controlled Trial Comparative Study Clinical Trial
Decreasing catheter colonization through the use of an antiseptic-impregnated catheter: a continuous quality improvement project.
To evaluate the use of an antiseptic-impregnated (chlorhexidine and silver sulfadiazine) catheter for the prevention of catheter colonization and catheter-related bloodstream infection (CR-BSI). Then, based on these findings, to implement changes in hospital policy and to assess their effect on a hospital service. ⋯ AICs significantly reduce the rate of central venous catheter colonization. In addition, the apparent protective effects of the catheter over time permit less frequent exchanges or removals of the catheters, decreasing both patient risk and hospital cost.

Bedside evaluation of efficient airway humidification during mechanical ventilation of the critically ill.
To determine the correlation between simple rating of condensation seen in the flex-tube connecting the heating and humidifying device used with the endotracheal tube and hygrometric parameters (absolute and relative humidity and tracheal temperature) measured by psychrometry. ⋯ In mechanically ventilated ICU patients, visual evaluation of the condensation in the flex-tube provides an estimation of the heating and humidifying efficacy of the heating and humidifying device used, thus allowing the clinician bedside monitoring of airway humidification.

Comparative Study Clinical Trial
Infusion phlebitis in patients with acute pneumonia: a prospective study.
To prospectively assess the relative risk for phlebitis in a series of consecutive patients with pneumonia and to identify risk factors that predict an increased risk for phlebitis. ⋯ According to our data, when the use of a catheter is expected to be required for < or = 36 h, a short line can be used. If a longer duration is expected, a longer line is warranted. Ours is the first study in which the relationship between blood hemoglobin levels and phlebitis has been reported. Because the use of intravascular devices is increasingly common, a more complete knowledge of the factors that influence their acceptance has become essential.

Comparative Study Clinical Trial
Diagnosis of nosocomial pneumonia in cancer patients undergoing mechanical ventilation: a prospective comparison of the plugged telescoping catheter with the protected specimen brush.
Quantitative culture of protected samples of lower respiratory tract secretions obtained by a fiberoptic protected specimen brush (PSB) is widely accepted for the diagnosis of ventilator-associated pneumonia (VAP), but this diagnostic procedure is time consuming, expensive, and may give rise to iatrogenic complications, especially in cancer patients who often present with thrombocytopenia. The plugged telescoping catheter (PTC) could be a satisfactory alternative to the PSB in this setting. The aim of the present study was to evaluate the interest of the PTC to diagnose VAP in ventilated cancer patients. ⋯ We conclude that the accuracy of the blinded PTC compares well with that of the PSB for the diagnosis of VAP in cancer patients. The sensitivity of the PTC observed herein, which is slightly lower than that described in previous studies, may be due to the blinded nature of the method: the indications for initial or secondary coupling with a directed sampling method in patients with suspicion of localized pneumonia remain to be determined.
