简要总结
Pleural diseases are among the most common clinical problems encountered in healthcare settings in Malaysia and even worldwide. Most patients presented in a hospital setting with pleural diseases will need pleural aspirations or thoracentesis and chest drains for a variety of reasons. Healthcare providers will often be exposed to patients requiring pleural drainage hence it is important to be aware of safe techniques and procedures of insertion and also maintaining the pleural drainage systems to yield beneficial results.
Most often, smaller catheters were deemed to be less effective in view of slower drainage rates and associated with high risk of blockage. However presently , in tertiary hospital settings small bore intercostal chest catheters (SBICC) have become an alternative to large bore intercostal catheters (LBICC). SBICC has been found to be equally effective, less painful and easily tolerated by patients. Hence, proper maintenance of SBICC should be undertaken to reduce rates of occlusion and to yield most benefits from the pleural aspirations procedures.
British Thoracic Society in their latest guidelines recommends the use of small bore intercostal chest drain as the first choice in draining pleural effusions.
The success of draining pleural effusions with a SBICC has shown variable rates of success among different studies conducted. Most common issues faced are drain blockage and drain dislodgement.
There is limited data comparing the use of normal saline flushing versus fibrinolytic drug lock in maintaining patency of small bore intercostal chest drains in draining pleural effusions. This has lead us in conducting this research to compare the rates of partial or complete occlusions among normal saline flush with and without heparin saline lock in maintaining the patency of small bore intercostal chest catheter among patients with pleural diseases in Hospital Canselor Tuanku Muhriz, UKM requiring chest drains insertion.
详细描述
Hypothesis
- Rate of occlusion is less in group with Heparin Saline lock.
- Rate of occlusions is higher in patients with exudative effusions. e.g : Empyema, raised pleural fluid LDH, low pleural pH, positive pleural cultures.
- Onset of ICC occlusions is lower in group with Heparin Saline lock.
- There is no difference in blood parameters between 2 groups.
- There are no apparent adverse effects between 2 groups.
- Patients in group with Heparin Saline lock have lower numbers of fenestration occluded.
Significance of Research Pleural diseases are among the most common diseases encountered in tertiary hospitals in Malaysia. Healthcare providers will need to provide adequate drainage of pleural fluids to improve the treatment outcome of patients. One of the mainstays of treatment is to ensure adequate drainage by reducing the rate of blockage of chest drains. This study is a pilot study to determine the efficacy as well as to ascertain the safety profile of using normal saline vs heparin saline lock for small bore intercostal catheters among pleural disease patients.
Type of Study Study on the Safety and Efficacy of 8 Hourly Flushing of ICC with and without Heparin Saline Lock in Maintaining Patency of ICC (SENSHIP Trial) is a prospective open label randomized controlled trial , a pilot study of patients admitted with pleural diseases in need of small bore intercostal catheters in Hospital Canselor Tuanku Muhriz, HUKM.
Standard Of Care Current Standard of Care in managing ICC in pleural diseases follows the recommendation of British Thoracic Society Guidelines where it suggests for regular flushing of ICC. The guideline recommends flushing of the tube by instilling 20-30ml of Normal Saline flush every 6 to 8 hours by a three way stopcock. However, this guideline only recommends regular flushing with Normal Saline and no research has been conducted to compare the outcome of effusions drainage and rates of blockage in small bore chest tubes with different techniques of flushing. Despite regular flushing with Normal Saline solutions as recommended, the rate of blockages in ICC still remains high. Hence, by adapting the concept of Heparin Saline Lock in IJC to maintain the patency of the tubing, we would like to study the difference of regular 8 hourly Normal Saline flushing with and without Heparin Saline Lock in maintaining ICC. Participants in this study who are chosen into Heparin Saline Lock arm will be receiving approximately 2ml of Heparin Saline as locking solution in attempt to maintain the ICC tube.
