Background We have previously described the utility of ThoraQuik, a device designed to be fit for purpose for aspirations of pneumothorax and pleural effusions. We evaluated the safety, efficacy and operator handling of the evolved prototype, ThoraQuik II, which has a lesser profile and a spring loaded Veres needle for added safety.

Methods A prospective, observational clinical trial with ethics and MHRA approval was conducted in a single centre. Patients with diagnosed pneumothorax (including tension pneumothorax) and pleural effusion were consented and recruited. The ease of device introduction, penetration and ease of use were evaluated. Clinical and radiological improvements were the clinical endpoints and operator feedback was analysed.

Results 20 procedures were performed on patients (mean age: 63.4 years (range: 30–90 years) with 75% male subjects) recruited between September 2008 and August 2009. Nine patients had pneumothorax (tension pneumothorax n=4) and 11 had pleural effusions. 19 patients completed the study with symptomatic and radiological resolution. One patient was withdrawn due to poor pain threshold disproportionate to the procedure. No complications were encountered. 68% had complete clinical and radiological resolution and 32% had partial resolution (these patients needed a definitive drain and hence were not aspirated to completion). The operator feedback in the study rated the device as very good or excellent in 90% patients.

Conclusions Our study found the use of ThoraQuik II to be safe and easy in draining pneumothorax and pleural effusions. The changes to ThoraQuik II made it more user friendly.
