Abstract
A method for assessing nerve health during a surgical procedure includes: applying one or more electrical stimuli proximate to the target nerve during the surgical procedure; detecting a muscle response evoked by the one or more electrical stimuli; determining at least one nerve function parameter indicative of the health or function of the target nerve; identifying a target range for the at least one nerve function parameter adapted for the target nerve, the target range being predictive of a desired nerve health status of the target nerve; and outputting an indication of the determined at least one nerve function parameter relative to the identified target range to provide real-time feedback during the surgical procedure involving the target nerve.
Claims22
A method for assessing nerve health during a surgical procedure involving a target nerve of a subject, the method performed by a system comprising a processor, the method comprising:
- applying, via a stimulator controlled by the processor, one or more electrical stimuli proximate to the target nerve during the surgical procedure;
- detecting, by a sensor communicatively coupled to the processor, a muscle response evoked by the one or more electrical stimuli, the muscle response originating from a muscle innervated by the target nerve;
- determining, by the processor based on the detected muscle response, a value of at least one nerve function parameter indicative of the health or function of the target nerve;
- identifying, by the processor, a target range for the value of the at least one nerve function parameter, wherein the target range is:
- predictive of a desired nerve health status of the target nerve;
- and
- based, at least in part, on an attribute of the subject;
- a comorbidity of the subject;
- and/or an assessment of a pre-operative neurological function of the subject or the target nerve;
- and
- outputting, by the processor for presentation on a display device, an indication of the determined value of the at least one nerve function parameter relative to the identified target range to provide real-time feedback during the surgical procedure involving the target nerve.
A system for assessing nerve health during a surgical procedure involving a target nerve of a subject, the system comprising:
- a stimulator configured to apply electrical stimuli proximate to the target nerve during the surgical procedure;
- a sensor configured to detect a muscle response evoked by the electrical stimuli from a muscle innervated by the target nerve and generate sensor signals indicative thereof;
- a display device;
- and
- a processor communicatively coupled to the stimulator, the sensor, and the display device, the processor configured to:
- control the stimulator to apply the electrical stimuli;
- determine, based on the sensor signals, a value of at least one nerve function parameter indicative of the health or function of the target nerve;
- identify a target range for the value of the at least one nerve function parameter, wherein the target range is:
- predictive of a desired nerve health status of the target nerve;
- and
- based, at least in part, on an attribute of the subject;
- a comorbidity of the subject;
- and/or an assessment of a pre-operative neurological function of the subject or the target nerve;
- and
- control the display device to present an indication of the determined value of the at least one nerve function parameter relative to the identified target range to provide real-time feedback during the surgical procedure involving the target nerve.
