Comparison of Function of Commercially Available Pleural Drainage Units and Catheters: Smaller-bore chest tube

Comparison of Function of Commercially Available Pleural Drainage Units and Catheters: Smaller-bore chest tubeThis problem is compounded by the absence of flow rate information in the packaging with either PDUs or PDCs. This absence of information leaves the clinician unable to compare flow characteristics of these devices and objectively choose the optimal device fitting the clinical situation. The absence of packaging information regarding the accuracy of pressures generated by PDUs further complicates the picture. These factors prompted the current study. http://buy-asthma-inhalers-online.com/ventolin-inhaler-100mcg-salbutamol.html
The multiple flow rate differences among the tested PDCs highlight the need for clinicians to pick the appropriate catheter for specific patient circumstances. This is particularly important in circumstances where high flow rates (persistent large bronchopleural fistulae) may be encountered. The popularity of smaller-bore PDCs, despite some offering potentially dangerous low flow rates, potentially worsens the situation. Contributing to this popularity is the intuitive notion that smaller PDCs, particularly those incorporating the Seldinger technique (guidewire placement), may be less painful to place than the traditional larger-bore tubes often placed by blunt dissection; however, a limited assessment of this issue indicates that smaller-bore catheters placed for simple aspiration of a pneumothorax appear less painful compared to traditional chest tube placement based on their average daily pain score, not from pain during tube placement. The clinician should not hesitate to choose a traditional large-bore chest tube if the situation warrants; however, knowledge of the flow rates of the PDCs tested in this study may allow clinicians to safely select a smaller-bore chest tube.
The maximal flow rate accommodated of the PDCs tested at — 20 cm H2O, as expected, was from the largest-bore PDC tested, the 24F Cook C-TQTS-2400 (Table 2).
