Physician's Orders; Wound Assessment - Medela Invia Motion Mode D'emploi

– Patients with infected wound or osteomyelitis.
– Wounds that involve an enteric fistula.
– To minimize the risk of bradycardia, NPWT must not be placed in the proximity of the vagus nerve.
– Avoid circumferential dressing applications.
– The Negative Pressure Wound Therapy must be used 24 hours per day without interruption. If the
pump is stopped for more than 2 hours, the dressing must be changed and therapy restarted.
– Consider the patient's size and weight when prescribing this device.
– Consider mode of therapy – intermittent versus continuous.
– For maximum benefit on closed surgical incision, the Invia negative pressure therapy should be
applied immediately post-surgery to clean surgically closed wounds. It is to be continuously applied
for a minimum of two days up to a maximum of seven days, with regular dressing changes every 48
to 72 hours. All dressing changes should be applied under direct medical supervision. The Invia
therapy system will not be effective in addressing complications associated with the following:
– Ischemia to the incision or the incision area
– Untreated or inadequately treated infection
– Inadequate hemostasis of the incision
– Cellulitis of the incision area

Physician's orders

A medical professional must assess each wound when applying this therapy and determining negative
pressure intensity according to the wound characteristics. Therapy or setting changes may only be done
under the order of a physician.

Wound assessment

CAUTION
Patient monitoring: The patient should be monitored regularly according to the physician's
instructions and facility guidelines to check for patient comfort, therapy compliance and signs of
infection.
WARNING
Objective indications or signs of a possible infection or complication must be addressed immediately
(e.g. fever, pain, redness, increased warmth, swelling or purulent discharge). Non-observance can
lead to con si de rable danger to the patient.
Observe the wound/periwound tissue and exudate for signs of infection or other complications. The most
common signs of infection include redness, tenderness, fever, swelling, itching, increased warmth in the
wound area, strong odor or purulent discharge. Additional symptoms include nausea, vomiting, diarrhea,
headache, dizziness, fainting, sore throat with swelling of the mucous membranes, disorientation, high fever
(>38.8° C), refractory hypotension, orthostatic hypotension, or erythroedema (a sunburn-like rash). More
serious complications of infection include pain, discomfort, fever, gangrene, toxic or septic shock. If more
serious complications of infection occur, discontinue therapy and consult a healthcare professional
immediately.
