Depth of anesthesia monitoring is always a concern for anesthesiologists; too shallow or too deep can cause physical or emotional harm to the patient. Maintaining the proper depth of anesthesia is important to ensure patient safety and provide good surgical conditions.

To achieve appropriate depth of anesthesia monitoring, three conditions need to be ensured.

1. an experienced anesthesiologist.

2, an anesthesia depth monitor.

3. a disposable EEG sensor used in conjunction with the anesthesia monitor.

The EEG sensor plays a decisive role in telling the anesthesiologist what level of anesthesia the patient’s EEG signal has reached to avoid over-anesthesia accidents.

The depth of anesthesia sensor was used for intraoperative monitoring during a difficult surgery performed in a tertiary care hospital in Shenzhen. The patient in the case study was faced with a multidisciplinary procedure that required the full cooperation of the anesthesiology department, spine surgery, joint surgery, infection department, and respiratory medicine department. According to the attending surgeon’s protocol, four surgical procedures were required. During the meeting discussion, the anesthesiologist raised the question: whether it was possible to safely anesthetize the patient, which was a decisive prerequisite for the entire operation.

Since the patient’s jaw is close to the sternum, it is difficult to access the anesthetic cannula, which deepens the risk of surgery. We all know the importance of anesthesia in surgery, and there is no way to perform surgery if anesthetic cannula is not possible.

In the picture we can see the important role of MedLinket anesthesia depth sensor in this difficult and demanding surgery. The depth of anesthesia sensor, based on the interpretation of an EEG signal, is an intuitive reflection of the cortical EEG, reflecting the excitation or inhibition state of the cerebral cortex.

This anesthesia operating room magic tool – depth of anesthesia sensor, so far has saved countless patients, so now even the operating room nurse practitioner knows that the word “deep anesthesia” in the anesthesiology department is not to be used indiscriminately.

“Deep anesthesia surgery is like a battlefield, and it is the battlefield of mine warfare, who does not know if they step on a mine today.

MedLinket Disposable Non-invasive EEG Sensor

BIS monitoring indicators:

BIS value of 100, waking state.

BIS value 0, state of complete absence of electroencephalographic activity (cortical inhibition).

Generally considered.

BIS values of 85-100 as a normal state.

65-85 as a sedated state.

40-65 as anesthetized state.

<40 may present burst suppression.

MedLinket produces disposable non-invasive EEG sensors (EEG dual frequency index) that are compatible not only with BIS TM monitoring devices, but also with multi-parameter monitors with BIS modules from mainstream brands such as Mindray and Philips for non-invasive monitoring of patient EEG signals.

There are also products compatible with other depth-of-anesthesia technology modules, such as EIS module for Universal Medical Entropy Index, CSI module for EEG state index, and Masimo’s depth-of-anesthesia technology products.

MedLinket Disposable Non-invasive EEG Sensor

Product advantages are as follows:

1.No sandpaper wipe to exfoliate, reduce workload and avoid wipe to cause resistance not to pass;.

2.Small size of electrode does not affect the adhesion of the brain oxygen probe; single patient disposable use to prevent cross infection.

3.The use of imported conductive adhesive, low impedance, good adhesion, optional waterproof sticker device.

4.Through the biocompatibility test, no cytotoxicity, skin irritation and allergic reactions, can be used safely and securely.

5.Sensitive measurement, accurate value, strong anti-interference ability, help anesthesiologists to closely monitor unconscious patients and give corresponding control and treatment measures in time according to the monitoring situation.

6.Has passed the national medical device registration certification, and is recognized by professional anesthesiologists at home and abroad in favor, has been successfully stationed in foreign authoritative medical institutions, several well-known domestic tertiary hospitals, to help anesthesia and ICU intensive care accurate monitoring of anesthesia depth indicators.
