“…The literature also demonstrates that this technique diminishes the occurrence of pulmonary dysfunction in the postoperative period and that its use after extubation, for a period of between 30 minutes and four hours, is associated with an increase in the PaO 2 and a reduction in PaCO 2 , when compared to the period of spontaneous ventilation with or without an oxygen supplement [5,14,15]. Hence, similar to this study utilizing non-invasive ventilation for 30 minutes immediately after extubation, there was a statistically significant improvement in the PaO 2 and a slight reduction in the PaCO 2 .…”

Benefícios da ventilação não-invasiva após extubação no pós-operatório de cirurgia cardíacaBenefits of non-invasive ventilation after extubation in the postoperative period of heart surgery Abstract Objective: to show the benefits of the use of non-invasive positive pressure ventilation (NPPV) in the process of weaning from mechanical ventilation in the immediate postoperative period of heart surgery.Methods: A prospective, randomized and controlled study was performed involving 100 consecutive patients submitted to coronary artery bypass grafting or valve surgery. The subjects were admitted into the Intensive Care Unit (ICU) under mechanical ventilation and randomized in a study group (n=50), which used NPPV with bilevel pressure for 30 minutes after extubation, and a control group (n=50) which only used a nasal O 2 catheter. Anthropometric variables and the times of the intra-operative periods corresponding to anesthesia, surgery and cardiopulmonary bypass, as well as the time required for weaning from invasive mechanical ventilation were analysed. The arterial blood gases and hemodynamic variables were also assessed before and after extubation.Results: The evolution was similar for the control and study groups without statistically significant differences of the variables analyzed except for the PaO 2 . On comparing the groups, the PaO 2 improved significantly (p = 0.0009) with the use of NPPV for 30 minutes after extubation, but there was no statistically significant difference in the PaCO 2 (p = 0.557).Conclusion: The use of NPPV for 30 minutes after extubation improved oxygenation in the immediate postoperative period of heart surgery.

“…169 Although cardiac and thoracic surgery may be considered high-risk procedures, the actual incidence of respiratory failure with these types of surgery is relatively low. 89,91,95,[97][98][99] For the purposes of these guidelines, low risk was necessarily defined by the surgical procedure alone, as no trials specified that their respective patient populations were uniformly at low risk. As such, trials of low-risk surgical procedures might have included patients with comorbidities that would place them in either high-or low-risk categories.…”

“…Trials of the use of noninvasive ventilation in patients who underwent lowrisk surgical procedures were generally small and reported only physiologic outcomes or found no difference in endotracheal intubation, hospital mortality or length of stay. 89,91,95,[97][98][99][102][103][104][105][106][107]109,111 The only exception was a recent large trial of continuous positive airway pressure by mask in 468 patients after cardiac surgery. 101 There was a reduction in a composite end point of pulmonary complications (arterial pressure of oxygen/fraction of inspired oxygen < 100, pneumonia or reintubation) and readmission to the ICU or an intermediate care unit.…”
