In previous posts we have discussed how brain injuries might occur, and the dramatic impact they can have on the life of the person who suffers from them. As a part of the treatment for TBI, brain sensors are sometimes used, including the introduction of a new wireless sensor.
In some cases, these sensors may be used to monitor the pressure in the patient's brain. Controlling the pressure can help reduce, or eliminate, adverse side-effects. Though these monitors can help to attain a positive outcome, there are ways in which they could be harmful as well. The fact they are hardwired into the brain could lead to haemorrhage, infection and allergic reactions. In turn, any of these could result in additional harm to a TBI patient.
Researchers have created new wireless sensors that could change this. Made of materials that are naturally biodegradable, the sensors are wireless and, after a few weeks, dissolve. They are smaller in size than a grain of rice and are connected to a wireless transmitter inserted on top of the skull of the patient. The transmitter is small, as well-approximately the size of a postage stamp.
Though they have yet to be used on humans, tests conducted with the sensors have been successful. Should they be made available for human use in patients suffering from TBI, it is possible certain risks associated with the recovery could be reduced, preventing any further harm to the patient.
