Clinical Trial Summary

Conventional oxygen therapy (COT) is the main supportive treatment administered to patients postoperative after planned extubation and has conventionally been delivered using nasal prongs, cannula or masks. However, the maximal oxygen flow rates that these devices can deliver are limited. Being diluted by the ambient air which reduces the fraction of inspired oxygen is not only the main concern, but also COT is difficult to meet the requirements of heating and humidification in extubated patients. Yu Y, et al. (2017) High-flow nasal cannula (HFNC) can supply a mixture of air and oxygen via a heated and humidified circuit at a very high flow. It can provide almost pure oxygen with a FiO2 of approximately 100% and a maximal flow rate up to 60 L/min. The use of a HFNC may generate a positive airway pressure, ameliorate oxygenation and dyspnea, reduce the respiratory rate and work of breathing, and improve comfort. Yu Y, et al. (2017) Few studies were conducted in the past 5 years; and the effect of HFNC therapy compared to COT in patients after planned extubation remains inconclusive. This study will be done to compare the usage of HFNC as an alternative to the conventional oxygen therapy following extubation for patients undergoing pulmonary resection. Youfeng Zhu, et al. (2019)

Clinical Trial Description

Postoperative interventions effective in the reduction of pulmonary complications include good pain control, incentive spirometry, oxygen therapy, intermittent continuous positive airway pressure (CPAP), and early mobilization. Simple techniques such as incentive spirometry and patient positioning have proven to be ineffective in countering atelectasis, which can occur postoperatively in as many as 90% of patients. Noninvasive ventilatory support in the form of CPAP has been used as both a prophylactic and therapeutic intervention to improve ventilation in postoperative patients. Although CPAP may prevent pulmonary complications, it is uncomfortable for patients because it is applied by a tight-fitting mask, and patients may complain of difficulty with communication, eating and drinking, and mobilization, and consequently compliance is often poor. Bilal M. Ansari, et al. (2016) Conventional oxygen therapy via nasal prongs or a facemask can supplement oxygen administration, in some of the patients specially those who have lobectomy, it is ineffective in compensating for loss in lung volume or in maintaining gas exchange. High-flow nasal cannula oxygen (HFNC) mainly delivers a flow-dependent positive airway pressure and improves oxygenation by increasing end-expiratory lung volume. It is considered to have a number of physiological advantages compared with other standard oxygen therapies, including the provision of positive end-expiratory pressure (PEEP), constant FiO2, and good humidification. More importantly, it can reduce the anatomical dead space. Youfeng Zhu, et al. (2019) HFNC can be widely employed for patients of all age groups in several types of respiratory failure from preterm infants to adults and is broadly used in ICU because of the ease of use, tolerability, and safety. Youfeng Zhu, et al. (2019) HFNC systems now are increasingly being utilized, as when compared to regular nasal cannula and facemask oxygen, HFNC appears to be linked to decreased level of respiratory complications and hypoxemia after lung resection. Yu Y, et al. (2017) Few studies were conducted comparing different modalities of oxygen therapy; however, the answer of this question is still controversial. Is HFNC should be used as an alternative to the conventional oxygen therapy for patients undergoing lung resection following extubation ? ;
