Use of 4DryField® PH for haemostasis:

Before using 4DryField® PH, the bleeding area must be cleaned and dried. Using the bellows applicator, spray 4DryField® PH generously and closely onto the source of the bleeding. The entire wound area should be covered in 4DryField® PH.

With larger parenchymatous haemorrhages, it may be necessary to apply pressure to the haemorrhage, using standard gauze, for example. The duration and level of pressure depend on the organ being treated, the heaviness of the bleeding, and the size of the wound area. Before removing the gauze, soak with physiological saline solution if necessary to make it easier to detach the gauze from the clot. If blood is oozing, pressure may not be necessary.


 

4DryField® significantly accelerates clotting time and significantly increases clot firmness, even in diluted blood.1


You can find further information on the product and its use for haemostasis in the current 4DryField® PH package information leaflet. Endoscopy and laparoscopy: 4DFLapTM is a single use applicator for manual administration of 4DryField® PH in endoscopic and laparoscopic surgery.


The top video shows a schematic illustration of how 4DryField® PH works as a haemostyptic agent and the video below shows an example of the use of 4DryField® PH for haemostasis in a robot-assisted partial kidney resection.




What quantity of 4DryField® PH is required for haemostasis?

The quantity of 4DryField® PH required depends on the surgical situation. Cover the bleeding areas generously with 4DryField® PH and make sure that the bleeding has stopped. 4DryField® PH can be used in a quantity of up to 1g/kg of body weight (Poehnert et al. 2015).
