Pleural Effusion, Malignant
Conditions
Brief summary
The primary goal of this study is to compare well-defined pleural effusion management success outcomes in patients with malignant or paramalignant pleural effusions who were treated with Indwelling pleural catheter insertion compared with those treated with siver nitrate pleurodesis. It is also to demonstrate the effectiveness of silver nitrate pleurodesis. It is also important to evaluate frequent adverse events of silver nitrate pleurodesis in patients with malignant pleural effusion
Detailed description
Dyspnea is present in 50% of patients with malignant pleural effusion and quality of life is significantly impaired. Chemical pleurodesis using various sclerosing agents is accepted as a palliative therapy for patients with recurrent, symptomatic, and malignant pleural effusions. Silver nitrate solution (SNS) is a valid sclerosing agent that induce a caustic injury to the mesothelium that results in an effective pleurodesis. However, various clinical parameters and biochemical factors affect the success of pleurodesis in symptomatic patients with MPE: symptoms and performance status of the patient, daily fluid drainage, primary tumour, and mainly lung reexpansion following pleural fluid evacuation. The pleural injectate consists of 50 mL 0.5% SNS with 10mL of lidocaine (25mg/5mL). An alternative treatment is intermittent or continuous drainage of the pleural fluid with a chronic indwelling pleural catheter.
Interventions
DRUGSilver Nitrate
First, pleural fluid drainage will be done after administration of 5 cc of local anesthetic lidocain1% either by insertion of chest tube (26F or 28F ) or by using ultrasonography. Pleural fluid drainage will be terminated when the patient want to cough to make sure that the pleural cavity is empty, then the sclerosant material will be injected, patients will receive 0.5% silver nitrate diluted in 50 ml distilled water with 10 ml of local anaesthetic lidocaine 1%.
First , insert the wire into the pleural effusion at approximately the anterior axillary line. A 1-2 cm incision is made over the wire. A chest wall tunnel (5-8 cm in length) is created with a counter incision. The catheter is pulled through the tunnel and out next to the wire. After dilation of the wire tract with a Teflon peel-away sheath, the indwelling catheter is inserted into the chest. The counter incision is closed primarily, and the catheter is secured to the skin medially with a suture.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Success rate of silver nitrate pleurodesis | One week | patients will be submitted to serial chest x-ray and evaluation of pleural fluid accumulation by chest ultrasound . |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Chest pain: VAS | One week | Chest pain will be evaluated by visual analog scale which varies from (0-10) in which grade 0 indicates no hurt and grade 10 which hurts worst |
| Dyspnea | One week | Dyspnea will be evaluated through the mMRC dyspnea scale ( modified medical research council dyspnea scale) which varies from ( 0-4) in which grade 0 indicates dyspnea with sternous exercise and grade 4 which indicates dyspnea with dressing or undressing |
