Brief Summary

Dexmedetomidine(DEX)is a potent and highly selective α 2 adrenergic receptor agonist. It has the pharmacological effects of sedation, hypnosis, analgesia, anti-sympathetic and neuroprotective. Its sedative effect is similar to normal sleep, and easy to wake up. DEX is widely used clinically because of its advantages and acceptable side effects. The best clinical use of DEX is uncertain, including intravenous, intramuscular, oral, intralnasal and sublingual administration. Its clinical recommended use is intravenous load infusion for more than 10 minutes, followed by continuous infusion. However, the clinical recommended usage is inconvenient, time-consuming and other shortcomings, for the growing popularity of daytime surgery, will inevitably affect the operation process and turnover. If a suitable dose range of DEX can be found for a single intravenous injection to achieve clinical efficacy quickly without significant hemodynamic effects, this will improve the patient's postoperative recovery. We will speed up the utilization and turnover of medical resources. The aim of this study was to investigate the optimal dosage of DEX for single intravenous injection.

Study Arms (1)

Dexmedetomidine

EXPERIMENTAL

Drug: Dexmedetomidine dexmedetomidine, 0.1ug/kg up or down Other Name: precedex

Drug: Dexmedetomidine

Interventions

Dexmedetomidine was injected intravenously 30 minutes before the end of operation. Single bolus is for more than 1 minute. In the first case, the dosage of dexmedetomidine was 0.1 ug/kg. If the cardiovascular reaction was positive (mean arterial pressure or heart rate was more than 20% before intravenous injection), the dosage of Dexmedetomidine in the next patient decreased by a gradient (0.05ug/kg). If the cardiovascular response was negative, the next patient increased the dose of dexmedetomidine by a gradient (0.1ug/kg); if a patient withdrew from the study, the next patient received the same dose as the patient who withdrew.
