验证全身甘氨酸通道状况

Before a general anesthesia is applied, it is necessary to attest the passage of glycine,i.d., how the glycine receptors run through the system of the patient's body, so that the anesthesia can be efficiently applied.

This is what I understand from relevant literature so far, but I need a confirmation of someones such as Yueyin and Jianming, who has solid knowledge in biochemistry, biology and eventually in medical science.
