What is an Anesthesia Record?

An Anesthesia Record is a detailed account of the procedures performed and the anesthesia administered during the peri-operative period. The recorded information includes:– Vital Signs

– Surgical Interventions (i.e. Tourniquets)

– Anesthetics Administered (Types and Amounts)

Why are Anesthesia Records Necessary?

• To Smooth the Transition from the Operating Room to the Recovery Room

• Guide for Future Procedures

• Legal Documentation of Events

The Earliest System; Hand-kept Records

These were a problem because they were:– Subjective– Often Illegible– Distracting to the Anesthesiologist During the

Procedure, Especially During Crises

Early Automated Systems; General Instrumentation

– Central Processing Unit– A/D Converter– Serial Board– Keypad

Automated Systems; General Functions

• Touch-Screen/Keypad User Interface

• Alarms

• Read Out, Recorded Blood Gasses

• Plotted Vital Statistics-- Heart Rate, Blood Pressure, Etc.

• Record of Procedures and Times when Each Occurred

• Record of Who Performed the Procedure

• Billing Information– Anesthesia Totals: Types Ordered and Amounts Delivered

Criteria for Judging a System

• Board Approval (FDA)

• System Outputs/User Inputs

• Cost

• Compatibility with Existing Instrumentation

• Training Involved in Implementing the System/User Interface

• Software Modification and Updates

• Additional Features

Datex-Ohmeda AS/3 Anesthesia System

Datex-Ohmeda AS/3

• Records and stores vital signs

• Records with preconfigured and customized record layouts

• Two way communication system (remote access)

• Reporting package (cost & outcome analysis)

• Electronic Anesthesia archive and database for reporting and analysis

Saturn Information System

Saturn Information System

• 32-bit for use with Windows NT

• User friendly

• Highly adaptable

• Security to prevent unauthorized access

• Timed movements of records from local level to servers

• Very expensive

Anesthesia Component Monitoring System

ACMS• Component Modularity

• Data Transfer Module: transferring patient’s vital signs and demographic info

• Recorder Module: patient data documentation

• Vue Link Module: interfacing to external devices

• Advanced alarm system of sounds and colors

Conclusions

• We recommend the ACMS because of its high modularity, easy integration into current environment, plenty of adaptations

Forecasts

• Units will become readily accessible from remote locations (ie. The home)

• The open architecture allows the system to be extended well into the future

• Will become more compact and mobile

• More customization to the individual or the doctor
