Introduction
During closed thoracic drainage, the drainage tube should be kept patent to effectively maintain negative pressure within the pleural cavity. The drainage tube and incision site must remain sterile throughout nursing care. The drainage bottle should be positioned 60–100 cm below the level of the chest to prevent fluid or gas from flowing back into the pleural cavity. Vital signs should be monitored regularly, with close observation of electrocardiographic monitoring, blood pressure, respiration, and other conditions.
The key points of nursing care for closed thoracic drainage include maintaining patency of the drainage tube, ensuring aseptic technique, and monitoring the patient's physical condition.
1. Maintaining Patency of the Drainage Tube
During the drainage period, it is essential to keep the drainage tube unobstructed. This effectively maintains negative pressure within the pleural cavity, facilitating the removal of fluid and air.
2. Ensuring Aseptic Technique
During nursing care, both the drainage tube and the incision site must remain sterile. The drainage bottle should be positioned 60–100 cm below the chest level to prevent backflow of fluid or air into the pleural cavity. Additionally, the fluid in the drainage bottle should be replaced daily to prevent infection of the pleural space.
3. Monitoring Physical Condition
Vital signs should be monitored regularly, including electrocardiographic monitoring, blood pressure, and respiration. Attention should also be paid to respiratory rhythm and rate, with accurate documentation. Any abnormal signs should be promptly reported to the physician for appropriate intervention.
In addition to the above measures, patients should practice effective breathing techniques. Throughout the drainage period, patients should maintain a positive mindset and actively cooperate with medical treatment.
