Filter by: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)
The interest of pulmonary rehabilitation for patients who underwent lung resection for cancer remains controversial. The investigators studied the effects of the RR and its impact on quality of life and level of anxiety and depression in patients. In 2011 and 2012 , an RR was proposed to the patients referred to our center after lung resection for cancer. Patients were assessed at entry and departure by 6minutes walk test , a visual analog pain scale , a quality of life questionnaire ( EORTC QLQ C30 ) and an anxiety questionnaire and Depression (HAD) . These same questionnaires were mailed 6 months after the end of the pulmonary rehabilitation .
Patients who agree to receive pneumonectomy will be arranged to measure the distance from the incisors to the corresponding anatomical landmarks, including the cardia, the inferior pulmonary vein, the carina, the azygos vein, the lower edge of the aortic arch, the upper edge of the aortic arch, and the cupula of pleura through " fiber measurement method within nasogastric tube " . After building regression equations with the above data, the distance from the incisors to these corresponding anatomical landmarks could be inferred by means of indexes including height and so on.
Previous studies have shown that the removal of the chest tube after lung surgery significantly improves pain symptoms and lung function. The criteria for chest tube removal still remain vague in modern thoracic surgery and rely on personal experience instead of evidence-based criteria. Every hospital has its own traditional standard fluid threshold and believes in that without adapting and comparing it not even after introduction of newer and more minimal-invasive operation technique. According to literature the traditional fluid threshold is varying from 100 to 500 or even more millilitre in 24 hours. Since pleural fluid resorption is proportional to body weight the investigators believe that a body weight related approach of chest tube management would improve safety and would allow an earlier chest tube removal without a higher rate of complication. In this way the investigators believe in improving pain management and in achieving earlier discharge of the patient.
Lung ventilation required for lung resection surgery induces a proinflammatory response including cytokine production and recruitment of leukocytes and macrophages in the lung associated with postoperative complications, mainly acute lung injury (ALI). The lung-protective ventilation has been shown reduce this inflammatory response and play a protective role against ALI, even though it is unclear the role of intravenous and inhalational anesthetic agents in immunomodulation of the inflammatory response during lung ventilation and its possible protective role against ALI. This study aims to determine the effect of anesthetic agents on markers of lung inflammation, the mechanisms of oxidative stress and ischemia-reperfusion, and assess the relationship between these mediators and postoperative morbidity defined as percentage of postoperative lung complications (ALI / ARDS, pneumonia and atelectasis), length of stay in ICU, hospital stay and mortality at 30 days. The investigators hypothesis, based on results of our group in animal research, is that inhalants cause a lower proinflammatory response to intravenous agents for lung resection surgery. A clinical trial is design with two groups (propofol, sevoflurane) managed all with lung protective ventilation, in which the markers will be measured before and after one-lung ventilation in both lungs and in plasma before, during and after one-lung ventilation. postoperative lung complications, ICU and hospital stay and 30 days mortality.
