Surgical Documentation — For Surgeons

The operative report
writes itself.

EigenH Theater captures live surgical narration in the operating theatre, tracks procedure phases in real time, detects critical intraoperative events, and generates a complete, structured operative report — without the surgeon lifting a pen.

Operative reports shouldn't be written from memory.

An operative report is one of the most important documents in a patient's surgical care. It is also one of the most consistently underdocumented. Surgeons are expected to dictate after a procedure — often after a six-hour surgery, immediately before another case. The result: reports missing details, reconstructed after the fact.

"The surgeon should think about the patient. Theater thinks about the report."

How Theater works.

Passive. Non-intrusive. Zero new behaviour for the surgical team.

1

OR Prep

Theater listens via OR audio feed. No new equipment in the sterile field.

2

Phase Tracking

Tracks preparation, access, dissection, resection, and closure in real time.

3

Narration Capture

Continuous transcription, separating surgical narration from ambient conversation.

4

Event Detection

Critical events flagged with timestamps — bleeding, device changes, technique variations.

5

Report Generated

Structured operative report auto-generated: indication, findings, complications, closure.

6

Review & Sign

Surgeon reviews on tablet or workstation. Every section sourced from OR audio.

What Theater can do.

Every word. Every phase. Every critical event — timestamped and sourced.

Live Narration Capture

Continuous OR audio transcription during the surgical procedure.

Procedure Phase Tracking

Tracks and timestamps each phase: prep, access, dissection, resection, closure.

Critical Event Detection

Identifies and flags unexpected intraoperative events in real time.

Operative Report Generation

Auto-generates report with all required clinical sections.

OR Video Integration

Connects with existing OR video systems for visual context and evidence.

Full Audio-to-Report Trace

Every report section sourced to a moment in the OR audio record.

Operative Report Structure

Theater generates operative reports in the standard format required by Indian hospitals and regulatory bodies.

Indication

Reason for surgical intervention, pre-operative diagnosis

Procedure Performed

Named procedure, approach, technique

Operative Findings

Intraoperative observations, anatomy encountered

Complications

Any intraoperative events, deviations from planned approach

Closure

Layers closed, drain placement, specimen disposition

Surgeon & Team

Attending surgeon, assistants, anaesthesiologist

Example: Laparoscopic Cholecystectomy

Report generation time from closure confirmation

Design Principles.

Cognitive Load is Zero

Surgeons don't press record, don't fill fields, don't dictate to a system. They operate. Theater handles everything else.

Passive and Non-Intrusive

No screens in the sterile field. No prompts during the procedure. The surgeon interacts with Theater only during post-case review.

Critical Events, Not Just Transcription

Theater understands what it hears. Unexpected bleeding, instrument changes, technique deviations — surfaced as flagged events, not buried in a transcript.

Evidence-Grade Accuracy

Every line of the operative report is tied to a timestamp in the OR audio. In the event of a complication or medico-legal review, the primary source is always available.

Built for the surgical team.

Surgeons

Primary User

  • Complete report at end of every case
  • Every section sourced from audio
  • Sign off in minutes, not hours

OR Nursing Staff

Secondary User

  • Automatic case log from event flags
  • Timeline as procedure record
  • No additional charting needed

Hospital Administrators

Configuration Owner

  • Set procedure type library
  • Configure OR audio/video integration
  • Define EHR submission workflow

Legal & Quality Teams

Institutional Stakeholder

  • Complete, timestamped operative record
  • Medico-legal documentation with source audio
  • No reliance on post-hoc recollection

Common questions.

What about sterile field concerns?

Theater uses existing OR audio infrastructure. Nothing new enters the sterile field.

Surgeons won't trust an AI-written report.

Surgeons review and sign every report. Theater drafts — surgeons decide. Nothing goes to the EHR without explicit surgeon approval.

What if it misses something?

Every section traces to the OR audio record. If it's not in the audio, it wasn't said. The surgeon adds it during review.

Is OR audio safe to process?

Theater runs entirely on hospital infrastructure. No OR audio or video leaves the premises. Fully compliant with DPDP Act 2023.
