You've been asked to evaluate a patient for negative pressure wound therapy (NPWT). It turns out they're a perfect candidate, so you start the process to have the unit placed immediately! The order is entered into the EHR for the recommended settings, and the initial dressing application is scheduled.
Let us pause for a moment and consider the following questions:
- Does the patient have pain?
- Has their pain been adequately assessed?
- What type of medication does the patient currently have ordered?
- Has anything been ordered for dressing change or breakthrough pain that often occurs with NPWT?
- Have any adjunctive methods been identified to implement in the event the patient's pain is not well controlled?
- Does the hospital have a guideline for managing pain in patients with NPWT?
There are so many factors to consider before treatment even begins!
NPWT is very advantageous in that it promotes tissue growth and proliferation via tissue strain, encourages wound contraction, provides exudate management, and reduces bioburden. The adherence of the typical NPWT foam dressing to the wound bed can be a source of significant pain during dressing changes.
Despite the evidence available that pain slows healing and recovery, many studies demonstrate that the health care system has not improved with regards to providing adequate pain control. The consequences of unrelieved pain can include activation of the body's stress response and disruption of the normal wound healing cascade. Pain, especially associated with wound dressings and NPWT in particular, is a multifaceted problem that must be managed with multiple modalities to facilitate an environment of holistic patient care.
A literature review reveals a multifaceted approach, including topical anesthetics prior to NPWT dressing changes and treatment variable modulation (pressure setting, wound contact layer, type of foam, etc.) can be effective in augmenting patient pain experience and decreasing opioid analgesic requirements.
The appraised evidence suggests that when formulating an individualized pain management plan for NPWT, the provider should consider the following interventions:
*Note that manufacturer guidelines should still be observed, and some of the above interventions should not be combined (e.g. PVA foam at less than 125mmHg). Consulting the representative of the company for the device is always a prudent idea when troubleshooting the device and settings to increase patient comfort.
We should always be our patients' most fierce advocates, especially where pain is involved. Working with the patient to manage pain not only fosters an environment of trust, but hastens the healing process. I plead with you to never forget that, and always keep the patient's best interests at the forefront of your thoughts.
I enjoy learning through the feedback of others, so please feel encouraged to share your thoughts, ideas, and experiences! Until we blog again…I leave you with this quote:
