Clinical Trial 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.


Description:

The chest tube drainage and needle aspiration are widely used first step techniques in spontaneous pneumothorax, thus present randomized controlled trial (RCT) aims to compare the efficacy of abovementioned techniques, as well as long-term outcomes. The study protocol has been confirmed by the ethics committee of AJA University. In current multi-center single-blinded RCT, all patients admitted with primary spontaneous pneumothorax will be enrolled study and written consent form provided by patients, simultaneously. With due attention to the success rate of 18% provided in a previous study comparing primary spontaneous pneumothorax treatment procedures and the study power of 80% and the confidence coefficient of 0.05, study population calculated to include 64 patient, which increased to 70 patients with taking 10% of falling risk into consideration. Using Randlist software, patients will be 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.

In chest tube drainage group, while the patient is positioned in the supine position and subsequent to 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. However, in needle aspiration group, patients will be positioned semi-supine. Subsequently, G16 intravenous angiocath will be inserted through the midclavicular line at the level 2nd or 3rd intercostal space. The catheter needle will be removed and catheter will be fixed using sterile sticks. A three-way valve will be connected to the 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.

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.

Study Design


Intervention

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.
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.
