Bleeding from pneumonectomy for more than half a year air incision should be a nameless artery injury, mainly because of wound infection, improper use of cannula or variation of blood vessel location.
1. Wound infection: after pneumonectomy, improper daily care leads to the wound being infected by bacteria, resulting in anonymous artery injury, which leads to bleeding from the pneumonectomy for more than half a year.
2. Improper use of cannula: During the pneumonectomy, the cannula chosen is too thick and too long, which rubs the trachea wall or blood vessel wall for a long time, thus causing the trachea wall and blood vessel wall to erode and bleed, and the wound is not completely healed, and the blood will ooze out from the wound.
3. Vascular position variation: after pneumonectomy, the use of cannula for too long, easy to form the end of the catheter at the end of the tracheal stenosis, blood vessels with the narrowing of the movement, the position of the variation, easy to be damaged, causing bleeding, and thus oozing out of the pneumonectomy incision.
After more than six months of tracheotomy bleeding from the gas incision, it is recommended to visit the hospital as soon as possible, inform the doctor, and replace the tracheal cannula under the doctor’s guidance.
