Abstract

Claims (40)

1. A method of identifying positioning effect in a patient, the method comprising:

stimulating one or more peripheral nerve structures with one or more electrical pulses from a stimulating electrode;

recording resultant electrical waveforms generated by a nervous system of the patient in response to the electrical pulses using a recording electrode;

detecting, by a computing device, a change in the resultant electrical waveforms;

analyzing, by the computing device, the detected change in the resultant electrical waveforms to automatically identify the positioning effect, the positioning effect comprising an immediate or potential injury to the one or more peripheral nerve structures due to stress associated with a position in which the patient has been placed for medical care or treatment; and

forwarding data to a display, the data comprising information for displaying an anatomical diagram that depicts a location of the detected change.

2. The method of claim 1 , wherein said at least one stimulating electrode is coupled to at least one of:

an arm of the patient;

a leg of the patient;

an ulnar nerve of the patient;

a median nerve of the patient; or

a posterior tibial nerve of the patient.

3. The method of claim 1 , wherein said at least one recording electrode is coupled to at least one of:

a trunk of the patient;

an Erb's point of the patient;

a head of the patient; or

a neck of the patient.

4. The method of claim 1 , wherein the peripheral nerve structure comprises one or more of the group consisting of: a peripheral nerve, a nerve root, a nerve trunk, a nerve plexus, a cord, and a division.

5. The method of claim 1 , wherein the resultant electrical waveforms are somatosensory evoked potential waveforms.

6. The method of claim 1 , wherein the change in the resultant electrical waveforms comprises a change in a latency, an amplitude, or a morphology of the resultant electrical waveforms.

7. The method of claim 1 , wherein analyzing the detected change comprises at least one of:

comparing, by the computing device, information based on the resultant electrical waveforms to information from an anesthesia machine to determine when changes in the resultant electrical waveforms are due to anesthesia; or

comparing, by the computing device, information based on the resultant electrical waveforms to information from a blood pressure machine to determine when changes in the resultant electrical waveforms are due to blood pressure.

8. The method of claim 1 , further comprising: determining how to reduce the positioning effect based on a position of a table.

9. The method of claim 1 , further comprising: providing information based on the positioning effect to a table.

10. The method of claim 9 , further comprising:

providing information to the table to at least partially reposition the table to reduce the positioning effect.

11. The method of claim 1 , further comprising:

adjusting a position of the patient based on the positioning effect using an electro-mechanism of a table.

12. The method of claim 1 , further comprising:

alerting a user to the positioning effect using at least one of:

a notification;

an alert;

a communication;

an indication; or

an alarm.

13. The method of claim 1 , further comprising:

displaying the information based on the resultant electrical waveforms on the display.

14. The method of claim 1 , further comprising: receiving a user input regarding an accuracy of the resultant electrical waveforms.

15. The method of claim 1 , wherein analyzing the detected change comprises averaging together the resultant electrical waveforms generated in response to several stimulations to reduce noise.
