Adhesion prevention and

Haemostasis with 4DryField® PH

4DryField®PH is a single medical device that provides both adhesion prevention and haemostasis in one application.

Adhesion Prevention

Postoperative healing without the formation of adhesions is subject to complex physiological processes and preconditions. 4DryField® PH gel covers the areas at risk of adhesion formation, provides a barrier that aids peritoneal healing, separates the risk areas, and minimises the development of fibrinous connections between them. This creates the optimal conditions for healing without the formation of adhesions. Furthermore, there are no side effects.

The 4DF Technology

How does 4DryField® PH work?

Adhesion prevention

Due to the molecular structure of 4DryField®PH, when liquid is absorbed (physiological saline solution), the microparticles form a gel that creates a temporary mechanical barrier against the formation of adhesions.

Arrest of bleeding / haemostasis

By absorbing liquid, 4DryField® PH causes a relative concentration of the patient’s own coagulation factors resulting in safe and fast haemostasis. Even with a 50% dilution of the blood, the coagulum induced by 4DryField® PH shows excellent stability.

Indication

Adhesion prevention4DryField®PH is indicated when the formation of postoperative adhesions needs to be prevented following surgery in cavities with a mesothelial lining (e.g. pericardium, chest cavity, abdominal cavity).

Arrest of bleeding / haemostasis 4DryField®PH is indicated in cases of surgical intervention or injury when the control of bleeding from arterioles, capillaries or veins is not effective or not practicable by means of conventional measures.

Why does adhesion prevention make sense?Adhesions are associated with postoperative complications, higher costs, and a heavier workload. In further surgery, adhesions may hamper a minimally invasive procedure and require more operating time e.g. for adhesiolysis. The risk of complications increases dramatically depending on the number and severity of previous operations. For patients, adhesions can result in chronic or recurrent pain, dyspareunia, infertility, and transit disorders – sometimes in the first year following surgery. The most serious complication is mechanical small intestine ileus, which is caused by adhesions in 65% to 75% of cases.
