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.
Procedure Timeline — Laparoscopic Cholecystectomy
Critical Event at T+34m
Unexpected bleeding at cystic artery — managed successfully
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.
OR Prep
Theater listens via OR audio feed. No new equipment in the sterile field.
Phase Tracking
Tracks preparation, access, dissection, resection, and closure in real time.
Narration Capture
Continuous transcription, separating surgical narration from ambient conversation.
Event Detection
Critical events flagged with timestamps — bleeding, device changes, technique variations.
Report Generated
Structured operative report auto-generated: indication, findings, complications, closure.
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

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.

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.
Theater is coming to operating rooms across India.
