Negative pressure therapy offers benefits to patients.

In the search for strategies to promote wound healing, medical researchers discovered that negative pressure offers a number of benefits.

What is negative pressure wound therapy?

Patients with acute, chronic or burn injuries first have their wound sterilized followed by the application of a dressing that creates a sort of seal. Once that step of the process is complete, doctors will attach a pump, which acts as a continuous vacuum to the traumatized area, Wound Care Centers explained. This results in negative pressure, which can be altered as medical professionals see fit. Healthcare providers can change the amount of suction present, time spent on the pump and whether the treatment will be a continuous or infrequent task.

What are the benefits?

Negative pressure aims to pull dangerous pathogens from the wound to ensure the injury is able to heal with a lower chance of infection. As a result, patients who undergo this therapy – especially those who have undergone vascular surgeries of the groin – can take advantage of faster rate of healing, fewer dressing changes and the opportunity to be discharged earlier from the medical facility where they’re receiving the treatment, according to a study completed by Lund University in Sweden.

“On average, the wound healing time was almost cut in half for patients who received negative pressure wound therapy — from 104 days to 57,” explained Christina Monsen, a doctoral student at Lund University and registered nurse, who worked on the research. “The in-hospital care time was also reduced by a week, to an average of 13 days compared to 20.”

More analysis into the non-invasive procedure is needed at time wears on, but the exploration up to this point has proven positive.

Important considerations

Negative pressure therapy isn’t without its concerns. This type of wound care won’t work for every patient. Instead, doctors have to assess the following factors, according to a study published in the Nursing Times:

  • Level of morbidity.
  • Potential for trips and falls.
  • State of mental health.
  • Position of injury and its ability to maintain the sealed dressing.
  • Amount of pain experienced during dressing changes.
  • Ability and willingness to comply with treatment requirements.
  • Risk of pulling dressing or tubes off injury.

Overall, negative pressure treatment offers patients and healthcare providers alike a number of advantages. However, careful selection of those undergoing the therapy is crucial to its success.
