Summary

General anesthesia with double-lumen endobronchial tubes intubation is the main anesthesia method in thoracic surgery.However, double-lumen endobronchial tubes intubation can produce greater stimulation and cause more cardiovascular reactions, and the ideal anesthetic drugs can effectively reduce adverse reactions.Remimazolam is a new type of benzodiazepine drug that can be safely used for the induction and maintenance of general anesthesia, and it is an ideal and short-acting anesthetic alternative.As the new drug has had a short clinical entry time.There are few clinical data in all aspects, so it is necessary to clarify its rational use in the induction of anesthesia.Dexmedetomidine is a highly selective α 2 adrenergic receptor agonist, and it is currently the most popular adjunct to clinical anesthesia.However, the clinical data of anesthesia induction by dexmedetomidine combined with Remimazolam are rarely reported.

In the case of prior use of dexmedetomidine, to explore 50% effective dose (ED50) and ED95 of Remimazolam for the induction of anesthesia to inhibit the cardiovascular response of double-lumen bronchial intubation, in order to provide more data for the rational use of remimazolam and a reference for clinical rational drug use.

Conditions

Interventions

DRUG

Dexmedetomidine

Dexmedetomidine is the most popular adjuvant to anesthesia. Groups was grouped according to different preadministered doses of dexmedetomidine. This allows a more comprehensive assessment of remimazolam under different use. Three groups were set separately, and Group A, Group B, and Group C correspond to 0,0.5, and 1 μg/kg at first 10 mins , respectively.

DRUG

Remimazolam tosilate

Remimazolam tosilate has a short clinical time and a lack of combination with dexmedetomidine for dual-lumen endotracheal intubation. The optimal use dose of Remimazolam tosilate was explored separately from different dexmedetomidine doses.
