Little is known about the incidence of and risk factors for adverse effects from endotracheal suctioning. We studied the incidence and risk factors, and evaluated the effect of suctioning practice guidelines. ⋯ Endotracheal suctioning frequently induces adverse effects. Technique, suctioning frequency, and higher PEEP are risk factors for complications. Their incidence can be reduced by the implementation of suctioning guidelines.

To evaluate the relationship between plasma N-terminal prohormone B-type natriuretic peptide (NT-proBNP) and weaning outcomes, and the ability of NT-proBNP level to predict weaning success, in cancer patients with pulmonary complications undergoing noncardiac major surgeries. ⋯ Measuring NT-proBNP at the end of a spontaneous breathing trial may assist in predicting weaning success, as a noninvasive, quantitative and repeatable indicator of cardiac stress in patients with postsurgical respiratory failure.

Observational Study[Evolution in muscle strength in critical patients with invasive mechanical ventilation].
To assess the evolution of muscle strength in critically ill patients with mechanical ventilation (MV) from withdrawal of sedatives to hospital discharge. ⋯ The greatest muscle strength gain after withdrawing of the sedatives was achieved in the first week. Muscle strength loss was associated with a cardiovascular SOFA > 2 and costicosteroids. Patients with a MRC < 48 required more days with MV and a longer ICU stay.

High tidal volume ventilation does not exacerbate acid-induced lung injury in infant rats.
The impact of mechanical ventilation with high V(T)-low PEEP in infant rats with preinjured lungs is unknown. After tracheal instillation of saline or acid, two week old rats were ventilated with V(T) 7 mL/kg and PEEP 5 cm H₂O or V(T) 21 mL/kg and PEEP 1cm H₂O for 4 h. Airway resistance and the coefficient of tissue elastance, measured via low-frequency forced-oscillation technique, and quasi-static pressure-volume curves deteriorated less with high V(T)-low PEEP when compared with low V(T)-high PEEP. ⋯ Moreover, differences in BALF protein concentration and histological lung injury scores were independent of applied ventilation strategies. In contrast to experimental studies with adult rats, short-term mechanical ventilation with high V(T)-low PEEP is not deleterious when compared to low V(T)-high PEEP in both healthy and pre-injured infant rat lungs. Our results call for caution when extrapolating data from adult studies and highlight the need for age-specific animal models.

Observational Study[Pain behaviour indicator scale (ESCID) application in severe non-communicative trauma patients receiving mechanical ventilation].
To assess pain in non-communicative patients with severe trauma undergoing mechanical ventilation prior to, during and after tracheal suctioning, mobilization and wound care. ⋯ An increase on the ESCID score was observed while performing the procedures.
