Bedside PDT

aScope 4 Broncho is the cost effective scope for Percutaneous Dilatational Tracheostomy 

Percutaneous Dilatational Tracheostomy is a routine procedure in the ICU

Percutaneous Dilatational Tracheostomy (PDT) is a common bedside procedure for prolonged mechanical ventilation in the adult critical care unit. Fibreoptic bronchoscopy (FOB) is recommended for routine use during a PDT procedure as it provides a direct view and enhances patient safety.

Clinical guidelines recommend use of bronchoscopy guidance during PDT 

Tracheostomy in the intensive care unit has become a routine procedure. This trend is reflected in updates of clinical guidelines recommending the immediate availability and use of flexible bronchoscopes and bronchoscopy guidance during PDT procedures.

Difficulty in managing the airway, including percutaneous tracheostomy placement, was the single most important cause of major anaesthesia-related morbidity and mortality disclosed in the extensive NAP4 review from March 2011. Based on the findings, it was recommended in the NAP4 report that a flexible bronchoscope should be immediately available on the ICU to assist with percutaneous tracheostomy placement as well as for regular checking of the position of tracheostomy tubes.

aScope 4 Broncho offers a clear endoscopic view allowing the operator to verify the accurate placement of the guidewire, needle and tracheostomy tube preventing harm to the patient.

Worried about damaging your bronchoscope during PDT?

A PDT procedure puts the bronchoscope at risk – in fact  31 hospitals in Germany, the UK and the USA reported that 1 in 27 bronchoscopes was damaged during PDT procedures. That is twice the risk of expected damages for other procedures performed with reusable bronchoscopes.2 

Repairs are costly and take time, with high impact on budgets and availability. These damages contribute to an already high cost of working with reusable bronchoscopes where you also have to consider acquisition and reprocessing costs. A study has revealed an average cost of $406 for every PDT procedure conducted with reusable bronchoscopes.2 

aScope 4 Broncho is the ideal alternative to reusable bronchoscopes for visual monitoring during PDT procedures allowing you to save $157 per PDT procedure.

aScope 4 Broncho Key Benefits

Easy to handle

The lightweight design of aScope 4 Broncho makes it easy to handle and the portability of the aScope system is convenient for bedside procedures in the intensive care unit.

Clear endoscopic view

aScope offers a clear endoscopic view that allows the operator to verify the accurate placement of the guidewire, needle and tracheostomy tube preventing harm to the patient. 

Clear cost advantages

The single-use concept has clear advantages in that it eliminates repair costs normally associated with the use of reusable bronchoscopes for PDT procedures. In addition, it increases patient safety as there is no risk of cross-contamination between patients.

Bronchoscopy guidance during PDT is likely to improve patient safety

Bronchoscopy guidance during PDT is likely to improve patient safety as it can guide the correct placement of the introducer needle, the guidewire and the cannula during the procedure.

With bronchoscopy guidance, severe complications such as perforation of the tracheal wall may be avoided.

Bronchoscopy guidance, however, is only one of several factors that improve patient safety during PDT.

According to Simon et al1 when performing PDT, strict consideration of contraindications, bronchoscopy guidance during the entire procedure, an experienced team, avoidance of a low tracheostomy puncture site and avoidance of guidewire kinking, as well as the use of outer flange tracheal cannula sutures are amongst the most important safety factors. 

Bronchoscopy guidance during the PDT procedure enhances patient safety

After the PDT procedure, correct placement of the tracheostomy tube is verified.
