The drainage of body secretions has seen continuous development over the
past 2000 years. In the early days, Hippocrates used small metal tubes to
drain the contents of abscesses. This technique was later improved upon by
introducing gold and silver tubes for drainage. Currently, vacuum systems
are in common use for postoperative drainage of wound secretions. However,
this technique is not without complications. Advanced technologies must be
applied to reduce the potential risks which are briefly summarized in the following.
Despite continual improvements being made in surgical techniques, the
incidence of postoperative inflammation in trauma surgery and following
orthopedic operations is reported at up to two percent in the literature.
In addition to these severe disturbances of wound healing, complications
such as postoperative swelling and hematoma, though less severe, also
significantly affect the postoperative outcome. Swelling causes delayed
mobilization which is associated with a pneumonia or thrombosis risk,
especially in elderly patients.
True asepsis, gentle management of soft tissues, insertion and withdrawal
of the drainage, and edema prophylaxis are essential requirements of
osteosynthesis and have a significant impact on wound healing.
Though the incidence of hematoma was reduced by the introduction of
vacuum drainage, hematoma and other disturbances of wound healing
continue to be reported in the literature despite the proper use of
the instrumentation, e.g. the reported incidence of postoperative
hematoma after total endoprosthesis varies between 1.2 and 22 percent.
Some of the complications of common vacuum systems cannot be prevented,
in fact they are caused by the systems. Complications typically relate
to the applied vacuum, frequent change of bottles with ensuing
infection risk, valve-like closure of the drain due to vital tissue
being suctioned into the drain leading to postoperative hematoma.
Aside from the factors listed above, which offer microorganisms ideal
feeding grounds and consequently reduce the probability of timely wound
healing the use of common vacuum systems is associated with a number of
additional infection risks:
- from the viewpoint of hygiene the bottles used in vacuum
drainage systems give rise to some concern related to errors
in the sterilization process and subsequent handling of the bottles,
- in some of the existing vacuum systems the product is quite
likely to contain residual quantities of the sterilization
gas or reaction products,
- another medical risk is posed by vacuum systems, some of
which are in common use today, in which the vacuum is reduced
depending on make and storage time.
Based on these considerations the following requirements for drainage
systems can be derived:
- fully closed sterile system from insertion until withdrawal of the drain,
- suction performance and vacuum of the closed system must be adjustable
to suit different types of wounds and stages of healing,
- cellular detritus and secretions must be completely drained
for the entire period of application,
- adequate internal wound surface adaptation without tissue damage,
- minimal blood loss, and
- unrestricted patient mobility and timely wound healing.
technology complies with these requirements. This technology
combines wound drainage, suction/irrigation drainage, and drainage-blood
refusion systems The DRAINTEC®
technology follows a very practical approach
in that it thinks and develops according to the requirements of the wound
and seeks to answer the question "what suits the wound best?". The
technology offers the highest degree of safety in that it is a completely
closed system from insertion until withdrawal of the drain which is
controlled by the wound, i.e. the volume of secretions produced, and
affords immediate mobilization of the patient thus promoting rapid wound healing.
technology is controlled by the patient and not vice versa.
With the drainTEC technology, the time of the inflexible universal drainages,
which were associated with uncertainties, contamination risks, and fear of
hematoma development, has come to an end.
