Comparing Efficacy of Chest Tube Drainage and Needle Aspiration in Pneumothorax Treatment

Summary

Spontaneous pneumothorax is a common condition which is defined as air presence inside of pleural space. Despite, several studies that have been carried on management patients suffering spontaneous pneumothorax, the first step approach on patients is still the topic of debate. Since chest tube drainage and needle aspiration are widely used first step techniques in spontaneous pneumothorax, current study compares the efficacy of abovementioned techniques, as well as long-term outcomes. In current multi-center single-blinded RCT, all patients admitted with spontaneous pneumothorax will be enrolled study and written consent form provided by patients, simultaneously. Patients randomly assigned to study groups including (A) chest tube drainage and (B) needle aspiration. Subsequently, all patients will undergo one-year follow-up and will be evaluated in terms of treatment success rate and pneumothorax recurrence. Hypothesis of present trial are as follows: a) repetitive needle aspiration may lead to higher treatment success rate in patients with primary spontaneous pneumothorax, in comparison to chest tube drainage, b) needle aspiration may result in reduction of hospital admission duration in patients with primary spontaneous pneumothorax compared to chest tube drainage, c) the rate of spontaneous pneumothorax recurrence during one-year follow up might be lower in patients who undergo needle aspiration instead of chest tube drainage.

Interventions

PROCEDURE

Chest tube drainage

In this group, in the supine position and subsequent to prepping and draping and local anesthesia administration via lidocaine 2%, F16 or F20 (based on patients physical status) sterile plastic tube will be implemented at the level 4th or 5th intercostal space through the midaxillary line. Subsequently, the external end of the tube will be connected to water sealing bottle and water bubbles coming out will be considered as proper chest tube insertion.

PROCEDURE

Repetitive needle aspiration

In this group, prior to needle aspiration, patients will take the semi-supine position. Subsequent to local anesthesia via lidocaine 2%, as well as prepping and draping, G16 intravenous angiocath will be inserted through midclavicular line at the level 2nd or 3rd intercostal space. Air bubble inside the lidocaine syringe will be considered as needled entrance to pleural cavity, thus 5-10 cm of the angiocath will be import to inside of the cavity. The catheter needle will be removed and catheter will be fixed using sterile sticks. A three-way valve will be connected to external end of the catheter and a 50 ml syringe will be connected to the valve. The air suction will be performed using 50 ml syringe till end of the air suction or up to 3.5 liters of air suctioning.
