(2) Common complications of tracheotomy 1, catheter shedding: often caused by unstable fixation. Managing the detachment is a very urgent and serious situation. If it is not treated in time, it will soon suffocate and stop breathing. 2, bleeding: can be caused by incomplete hemostasis during tracheotomy, or catheter compression, stimulation, rough sputum suction and other injuries to the tracheal wall. The patient feels pain in the sternum stalk or blood in the sputum. In case of massive bleeding, endotracheal intubation should be performed immediately to stop bleeding. 3. Subcutaneous emphysema: It is a common complication of tracheotomy. Emphysema mostly occurs in the neck and occasionally spreads to the chest and head. When subcutaneous emphysema is found, nail purple can be used to mark the edge of emphysema and observe the progress. 4. Infection: It is also a common complication of tracheotomy. It is related to the disinfection of indoor air, the pollution of sputum suction operation and the original situation. 5. perforation of tracheal wall ulcer: improper intubation after tracheotomy, or prolonged intubation, deflation and decompression when the balloon is uncertain, etc. Will lead to it. 6. subglottic granuloma, scar and stenosis: late complications of tracheotomy.
(3) Precautions in sputum aspiration 1. Sputum aspiration should be gentle and rapid to reduce the damage to the tracheal wall. Generally speaking, rubber or silicone catheter. 12 or no. Choose 14 with moderate hardness, smooth surface and relatively large inner diameter, or adopt autocratic sputum suction tube, or cut off the thick blind end at the front end of the catheter to make it concave crescent-shaped, and then cut two small holes on both sides to reduce the negative pressure at the head end and increase the sputum suction area. If the patient feels pain in the sternal stalk and there is blood in the sputum, he should be alert to the possibility of bleeding. In case of massive bleeding, rescue measures such as tracheal intubation and hemostasis should be implemented immediately. 2, pay attention to aseptic operation when sputum suction, wash your hands before operation, catheter strict disinfection, a catheter only once, adhere to the principle of from the inside out when sputum suction, first the secretions in the straw, then the nasal cavity and oral cavity secretions. 3. Take a deep breath 3-5 times before sputum aspiration. The user of the ventilator needs to hyperventilate for 2-3 minutes to increase the oxygen partial pressure in the alveoli, and then suck out the secretion quickly, accurately and gently with the sputum suction tube. It is forbidden to insert sputum tubes up and down. Sputum aspiration time is less than 15 seconds, especially in patients with respiratory failure. Long-term negative pressure suction can cause hypoxia, dyspnea and asphyxia. If there is too much secretion, it can't be sucked clean at one time, so hyperventilate or inhale again. 4. Before starting the aspirator, the suction tube must reach the depth of the trachea, or when starting the aspirator, fold the suction tube and the glass joint by hand to prevent leakage, and then extend the suction tube into the trachea to a certain depth before loosening the suction tube. 5. The suitable suction negative pressure is 6.7 kPa (50 mm Hg). 6. When sputum is sucked, patients often have cough reflex, which is beneficial to expectoration and sputum suction.
(4) Nursing of extubation Only when the extubation condition is stable, the respiratory muscle function is restored, the cough is strong, the sputum can be discharged by itself, and the dependence on tracheotomy can be relieved can the blockage test be carried out. When plugging pipes, 1/3 is blocked on the first day, 1/2 on the second day and completely blocked on the third day. If there is no dyspnea after 24-48 hours of occlusion, and you can sleep, eat and cough, you can extubate. Disinfect the fistula with 75% alcohol after extubation, and wrap it with butterfly tape for 2-3 days to heal. If it doesn't heal well, it can be stitched. Early extubation can reduce the occurrence of complications such as tracheal infection and ulcer.
