简要总结
Primary Aims:
To compare the performance of pigtail catheter to that of ICT in drainage of pleural effusion of medical aetiology regarding:
- Various complications(mainly wound pain) that result from either therapeutic approach.
- Success of complete drainage.
- Compare the duration needed for complete drainage.
Secondary Aims:
To evaluate both techniques in terms of:
- Degree of patient's mobility that either technique permits.
- Percentage of patients that can be managed on outpatient settings by either approach
详细描述
The pleural cavity is a space between the visceral and parietal pleura that contains a subtle amount of serous fluid (10 to 20ml) this fluid act as a lubricant to the pleural surface for proper gliding during respiration . Accumulation of abnormal amount of pleural fluid occurs under various pathological disorders, each of which manifests with a different physical and biochemical characteristics of the effused pleural fluid, it may be serous,pus,blood,or chyle.
Long standing undrained accumulated pleural fluid can lead to serious complications: like lung collapse leading to respiratory failure, fibrosis or scarring of the pleural membranes and underlying lung tissue, empyema, septic shock and even death in severe circumstance .
So we always seek to drain accumulated pleural fluid; Chest tubes connected to underwater seal have largely replaced open thoracotomy and rib resection in draining exudative pleural effusion and are now considered the standard method . However Intercostal tube drainage poses risks and hazards: large size of the tube that make it more painful more tissue destructive with more injury to intercostal arteries and nerves, the incisional insertion is also painful and results in more tissue dissection, moreover the tube is heavy as it need water seal to work so causing patient discomfort and increase liability of slippage.
Recently pigtail catheter has been employed to drain accumulated pleural fluid .pigtail catheter has many advantages: it has small caliber , which makes it less painful, less tissue destruction, less Injurious to intercostal nerves and vessels, Additionally it has a suction power with unidirectional valve which abolishes the need for underwater seal; thus avoiding the heavy weight of bottles and decreasing the risk of accidental slippage, inserted with trocar under ultrasonographic guidance decreasing liability of lung injury.
Previous studies compared pigtail versus chest tube in drainage of pleural effusion show .A total of 92 patients were included in the study, 57 (61.9%) patients in pigtail group and 35 (31.8%) in ICD group. Causes of pleural effusion included were pneumonia, malignancy,TB. the study had revealed that pigtail catheter had higher success rate less painful with no significant difference at mean duration of drainage..At other study data collected retrospectively from 60 patient aged more than 18 year 30 patients had an intercostal chest tube and 30 patients had pigtail catheters found that no statistically significant difference between pigtail and ICT at success rate and duration of drainage but pigtail found less painful with less incidence of complication regarding pneumothorax and catheter kinking and slippage .

结局指标
主要结局
1) Degree of Pain/discomfort elicited by the Intervention:
时间窗: 10 day
The visual analogue Scale from 0 TO 10 will be used to score reported pain or discomfort
2) Adverse outcomes complicating either line of intervention
时间窗: through study completion, an average of 1 year
(e.g., new onset pneumothorax or haemothorax, subcutaneous emphysema, fluid leakage around the wound, organ puncture, re-expansion pulmonary oedema, pneumonia, blockade of the drain, kinking or malposition).
3) Success of Complete Drainage
时间窗: through study completion, an average of 1 year
Number of patients with complete drainage: Complete drainage will be considered if all the following conditions are met: Amount of drained fluid \< 50 cc of serous/ hemo-serous fluid (no pus or gross bleeding) for two successive days. No accompanying air leak in the previous 12 hours. Radiological resolution (no residual free pleural fluid seen by chest US and lung expansion against chest wall as detected by chest US and CXR)
4) Duration needed for Complete Drainage:
时间窗: 15 day
Duration (in days) will be counted from the day of drain insertion to the day of drain removal
次要结局
- 6) Duration of Hospital stay.("through study completion, an average of 1 year)
- 5) Degree of Patient's Mobility:(0ne week)
- 7) Number of Patients Managed on Outpatient Settings.("through study completion, an average of 1 year)
