New System Allows Wound Checks Without Dressing Removal
In the United Kingdom, bioengineers at the Strathclyde Institute for Medical Devices, Glasgow, Scotland, have developed a new system that allows doctors and nurses to check the conditions under a dressing without having to remove it. A tiny sensor is attached to the gauze monitors to detect whether the wound is moist—the optimum environment for healing—or too dry or wet to heal properly. About half the size of a first class stamp, the sensor is attached via a sterile pad to the dressing itself, thus avoiding pain to the patient. It is connected to wires that can be plugged in to the monitor to allow doctors or nurses to take a reading.
The system is currently under clinical trial on patients with chronic leg ulcers with NHS Greater Glasgow and Clyde. It is anticipated it could be used for any kind of chronic or acute wound, including burns, chronic surgical wounds, and pressure ulcers.
