Pneumothorax/therapy, Drainage
Brief summary
The use of vacuum bottle in drainage of pneumothorax was seldom reported. This study aims to investigate the safety of vacuum bottle plus non-tunneled catheter for drainage of iatrogenic pneumothorax.
Detailed description
For aspiration or drainage of pneumothorax, a 16-gauge or 18-gauge over-the-needle non-tunneled catheter, a pigtail, or chest tube are frequently used to penetrate the pleural space. A 50-ml or 60-ml syringe may be connected to the over-the-needle catheter or a pigtail for simple aspiration, while underwater-sealed bottle or suction drainage connected to chest tube for drainage of pneumothorax. Vacuum bottle for removing pleural effusion are frequently reported in literature and common in daily practice. However, the use of vacuum bottle in drainage of pneumothorax was seldom reported. This study aims to investigate the safety of vacuum bottle plus non-tunneled catheter for drainage of iatrogenic pneumothorax.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intrapleural pressure during vacuum bottle air drainage | Within 1 hour | The investigator will measure the intrapleural pressure during air drainage at 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 15 minutes and until finished (the remaining with 5 minutes interval). It is proposed in previous studies that it is safe if the intrapleural pressure is less than 20 cmH2O during the procedure. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of reexpansion pulmonary edema | within 1day after the procedure | By calculating the rate of reexpansion pulmonary edema among vacuum bottle assisted drainage can investigator determine whether it is a safe procedure |
| The resolution rate of pneumothorax | 1 week | Chest X ray will be taken after the procedure and compared with that taken before the procedure. By using Rhea method, the investigator can compare the percentage of remaining pneumothorax compared with that before the procedure. |
