In addition to the usual disposable suction catheter, there is a Closed Suction System.The closed suction catheter is a layer of plastic bag on the coat of the suction catheter. The two ends of the suction catheter are closed, one end is connected with the endotracheal tube, and the other is connected with the suction catheter. Note that the closed suction catheter must enter the airway through the endotracheal tube.
Closed suction enables a clinician to clear the lungs of secretions whilst maintaining ventilation and minimising contamination with the least possible disruption to the patient.
Open suction vs closed suction | ||
item | Open suction | Closed suction |
method | Mechanical ventilation was withheld | Patients on continuous mechanical ventilation |
time | longer | shorter |
result | Not very good grasp the sputum suction tube, insert depth, easy to cause the airway mucosa injury and sputum suction is not complete. | It can accurately suction depth, reduce airway mucosal damage and locate the part with more sputum for thorough suction. |
pollution level | It produces a large number of microparticles containing bacteria, contaminating the surface of various articles and easily causing air pollution and cross infection. |
It does not cause air pollution and can avoid cross infection caused by sputum suction.
|
tolerance degree | It is not easy to tolerate, easy to be irritable, easy to cause chest tightness, shortness of breath, severe cough and dyspnea. | Easy to tolerate, slightly irritable, no obvious chest tightness, shortness of breath and dyspnea, choking cough. |
heart rate | It is not easy to cause arrhythmia due to offline hypoxia. | It will not cause arrhythmia due to off-line hypoxia. |
1. The parameters of disposable suction catheter were determined according to the needs of different hospital levels and departments.
For example, for intensive care units or operating rooms in higher-grade hospitals, disposable suction catheter with higher suction force and larger capacity may be needed to cope with complex conditions and large volumes of secretions during surgery. However, for general departments or low grade hospitals, the parameters of disposable suction catheter can be moderately reduced.
2. Choose the appropriate type.
Disposable suction catheter are usually divided into two types: direct suction and indirect suction. The direct suction disposable suction catheter is connected to a negative pressure suction device to attract secretions directly. The indirect suction disposable suction catheter is connected to an suction bottle or bag to attract secretions indirectly. According to the actual situation and budget of the hospital, select the appropriate type.
3. Disposable suction catheter material and quality also need to consider.
Single-use suction tubes are usually made of plastic or silicone, whereas plastic disposable suction catheter are more common. When selecting, it should be ensured that the material of disposable suction catheter conforms to the relevant standards of medical devices, such as non-toxic and sterile. In addition, attention should be paid to the quality of the disposable suction catheter to ensure its durability and reliability.
