Intraoperative nerve monitoring system PTA

neurosurgery

The purpose of PTA (Parasympathetic Tone Activity) technology is to provide veterinarians a noninvasive, easy to use monitoring system which offers a continuous and reliable measure of the parasympathetic tone of the animal via the ECG. Behavioral rating scales are widely biased due to their subjectivity and clinical context, which inhibits the behavioral response of the animal. PTA technology allows optimal management of analgesia particularly during surgery resulting in improved recovery. Following the results of the ANI technology (Analgesia Nociception Index) on the monitoring of non-communicating patients, the algorithm was adapted to develop the PTA. PTA technology offers the evaluation of the parasympathetic tone of the autonomic nervous system of animals. MDoloris developed a simple to use, non-operator dependent, heart rate variability analysis device, based on the acquisition of ECG signal. This has already been developed into specific measurements for three animal species: horses, dogs and cats Why assess COMFORT? The PTA technology provides an objective measure to evaluate the autonomic nervous system response to nociception, offering a value between 0 and 100, corresponding to the percentage of activity of the parasympathetic part of the autonomic nervous system of the animal. The higher the PTA value the higher the comfort of the animal is. In the absence of clear verbal communication, the expression of pain in animals is behavioral.
