The Adequacy of Anaesthesia (AoA) concept signals GE Healthcare’s commitment to provide clinical measurements for the components required for general anaesthesia. These measurements help the clinician deliver tailor-made anaesthesia to the patient.

Entropy measurement may be used as an aid in monitoring the effects of certain anaesthetic agents. In adults, it may help the user titrate anaesthetic drugs according to the individual needs and may be associated with a reduction of aneasthetic use and faster emergence from anaesthesia. Entropy monitoring is based on data acquisition and processing of raw electroencephalographic signals (State Entropy = SE) and frontal electromyographic signals (Response Entropy = RE).
The device that produces this measurement is the E-ENTROPY Module.

Published literature suggests that NMT measurements may help the clinician optimize dosage during anaesthesia1 and optimize recovery and prevention of respiratory complications in PACU.1,2,3,4

The Surgical Pleth Index (SPI)* is a parameter that reacts to hemodynamic responses caused by surgical stimuli and analgesic medications. Published literature suggests that SPI guided anesthesia may result lower remifentanil consumption1, more stable haemodynamics1 and lower incidence of unwanted events1.
SPI is an algorithm that uses two components of the GE plethysmographic signal obtained from E-PSM(P), E-PRESTN and E-RESTN Modules. SPI should be measured using specified GE SPO2 finger sensors only.

The configurable AoA split screen of GE’s CARESCAPE modular monitors, combined with hemodynamic parameters and respiratory gas measurements, provides a comprehensive visual view of patient’s status.
In the unique AoA split screen, you will find the BalanceView, which combines and plots Surgical Pleth Index (SPI) and SE values (one component of the Entropy measurement). This view helps the clinician monitor the effects of the analgesic and anesthetic pharmaceuticals during general anesthesia.
