About this file

This is a template and sample documentation for an Intraoperative Neuromonitoring (IONM) Communication Log used to record real-time neural monitoring data during surgical procedures. The document does not address specific contract requirements, deliverables, pricing, or service terms; rather, it serves as an operational tool for medical professionals to document baseline neurophysiological data, monitor changes during surgery, and communicate critical events to the surgical team.

The template demonstrates standardized documentation of neuromonitoring modalities including Somatosensory Evoked Potentials (SSEP), Motor Evoked Potentials (MEP), and Free-Run Electromyography (EMG) during a lumbar spinal fusion procedure. The sample case illustrates the communication protocol between technologists and physicians, event documentation procedures for significant waveform changes exceeding 50% amplitude reduction, immediate clinical responses such as retractor adjustment, and final case summaries confirming resolution of transient changes with no lasting neural compromise. This template appears designed to establish consistent documentation practices and communication protocols for IONM service delivery to the South Texas Veterans Health Care System under Solicitation 36C25726Q0274, but the document itself does not contain solicitation-specific requirements, timelines, pricing structures, or contractual terms.

3. Event Documentation

· Significant Change Criteria: >50% MEP amplitude drop

· Event Description: At 08:42, left tibialis anterior MEP amplitude decreased by ~60% from baseline.

· Immediate Actions: Alerted supervising physician and surgeon; surgeon paused, irrigated, and adjusted retractor.

· Surgeon Response: Retractor repositioned; surgical field inspected for compression.

· Follow-up Monitoring: MEP amplitude improved to 95% of baseline within 3 minutes.

· Resolution: No further changes noted for remainder of case.

4. End-of-Case Summary

· Final Waveform Status:

· SSEP: Stable, no latency or amplitude changes

· MEP: Stable, all muscle groups present and within baseline range

· EMG: No sustained activity

· Overall Interpretation: ☑ No significant lasting changes

· Physician Final Statement: “Transient MEP change resolved intraoperatively; no evidence of permanent neural compromise.”
