Intraoperative neuromonitoring (IONM) is an important procedure that helps to assess the functional integrity of the brain, brain stem, spinal cord, or peripheral nerves during and after complex surgical procedures. An IONM system uses recordings of potentials such as EEG and EMG from the nervous system during a surgical procedure. The use of neuromonitoring is important during surgeries as it helps in the detection of injuries or possible impairment of nerve function before, they become so severe that they cause post-operative complications in the patients. Therefore, IONM reduces risk of deficits such as muscle weakness, paralysis, hearing loss, and other normal body functions.
IONM provides immediate feedback and warning to the surgeon for the prevention of permanent nerve injury as a result of post-surgical damage. IONM is quick, painless, easy, and inexpensive. It can record the nerve function multiple times or even throughout the entire process of surgery.
The Intraoperative Neuromonitoring Market can be segmented by modality segment as Evoked Potential (EP) Market, Electromyography (EMG) Market and Electroencephalogram (EEG) Market, by service segment as In-source IONM and Out-source IONM and by application as Neurological surgeries, Orthopedic surgeries, ENT surgeries, Cardiovascular surgeries, and Other surgeries.
The Evoked Potential (EP) segment accounted for more than 50% of the market share in 2018. EP is an electrical signal generated by the CNS, which can be detected either by SSEP monitoring or TcMEP monitoring. SSEP monitoring involves the recording of the responses of the sensory pathways in the form of electrical stimuli. IONM is effective in improving surgical outcomes. Research studies by NCBI estimate that with the use of SSEP, there is a 60% reduction in complications associated with surgeries.
The Out-source IONM segment market was valued at $1540.9 million in 2017. Hospitals partially or fully outsource IONM services to service providers. Biotronic NeuroNetwork, SpecialtyCare, Neuro Alert, Sentient Medical Systems, and Computational Diagnostics are the leading service providers in the US. These companies provide advanced IONM devices, technologists, and physicians to hospitals to assist surgeons during surgeries.
Geographically, the market is divided into North America, Europe, South America, Asia-Pacific and the Middle East and Africa.
North America accounted for more than 45% of the market in 2018. The US accounted for more than 85% of the market share of North America in 2018. Increase in disease prevalence leading to surgical intervention, increased patient safety post-surgical treatment, high adoption of telehealth services, including remote neuromonitoring are the key impacting factors for North America market growth.
Some of the key players in the market are SpecialtyCare, Natus Medical Incorporated, NuVasive Inc., Medtronic Plc, Inomed Medizintechnik GmbH, Accurate Monitoring, Cadwell Industries Inc., Computational Diagnostics Inc., Nihon Kohden Corp., and Medsurant Health LLC.
