Received Date: 2003 a ll a 06; Revised :2003-12-26 Editor: Liu Jilie mechanical ventilation caused by tension pneumothorax in 3 cases of Xiao-Mei Chen 【Key words】 respiration, artificial / adverse effects; pneumothorax / etiology [in Key words 1R561.402.5 [Document code] B With the increasing application of mechanical ventilation for respiratory support extensive barotrauma serious complications as a potentially life-threatening, familiar,ugg uk, and the identification of the different signs of barotrauma, rapid diagnosis and timely treatment is important aspect of strengthening the management of mechanical ventilation. Now our analysis the following clinical data in this group were male, aged 8 to 85 years, drowning with acute respiratory distress syndrome, postoperative respiratory failure in one cases of gastric cancer, esophagus from 2002 to 2003, three cases of tension pneumothorax cancer, postoperative respiratory failure in 1 case. Tension pneumothorax occurred in three cases are the line to support the process of mechanical ventilation, ventilatory support,Moncler outlet, excessive moisture which ventilator settings 1 cases, subclavian vein catheterization 1 cases, the thoracentesis pumping one cases. Three cases in the event of a tension pneumothorax are sudden irritability, respiratory distress, the man-machine confrontation, airway pressure is increased, the ipsilateral chest,abercrombie fitch deutschland, knocking the drum sound, breath sounds disappear, lower blood pressure, underwent emergency bedside X-ray chest The piece is a clear diagnosis, the establishment of closed thoracic drainage, which the first two cases of thoracentesis, to continue mechanical ventilation. Which the occurrence of cardiac and respiratory arrest in 1 case. Two cases with good prognosis, and 1 died. Discussion described Macklin’s breathing on his own state barotrauma has changed markedly in the era of mechanical ventilation pressure injury, significantly increased the incidence of tension pneumothorax, become easily identifiable and more of a threat complications, 13% to 35% of barotrauma leading cause of death n]. Due to mechanical ventilation, the inspiratory alveolar maintain a positive pressure state in the event of pneumothorax, more than a tension pneumothorax, a life-threatening. Tension pneumothorax not only impair gas exchange, hemodynamics, and further damage the alveolar outside of the gas increased intrathoracic pressure, and change thy author: the comprehensive lcU250012 of Qilu Hospital of Shandong University [Article ID 1009-6647 (2004) 02 The -0302-01 output decreased, and compressed lung and pulmonary vasculature right heart afterload. The volume changes of the heart itself also reduced myocardial function, reduced cardiac output but no corresponding compensatory oxygenation improvement clinically in patients with hypoxic performance. Even cardiac arrest. The common reasons are: ① The improper application of mechanical ventilation, causing alveolar transmural pressure is too high, over-expansion of alveoli, leading to alveolar rupture; ② bullae rupture; ⑨ trauma or traumatic chest action [2]. Children mistakenly minute ventilation in this group is set to 14L/min, respiratory rate 14 times / rain, moisture excessive,Abercrombie Zü；rich, resulting in alveolar rupture in 1 case. The other two cases the implementation of the invasive chest operations. The application of mechanical ventilation, in particular the application of PEEP in patients with end-inspiratory and end-expiratory lung volume were increased, in such cases the implementation of the subclavian vein catheterization, easy to damage the pleura and lung. Cause pneumothorax. Therefore, to temporarily reduce the tidal volume, PEEP was adjusted to zero is a more secure manner. Injury has a protective effect of a new ventilation strategy to improve or reduce the pressure of mechanical ventilation in acute respiratory distress syndrome may occur. Such as pressure target ventilation or Permissive hypercapnia (PHC), pressure control ventilation (PCV) and inverse ratio ventilation (IRV,) Ca]. The bedside chest radiograph is the most valuable diagnostic tool.
