Summary

Dexmedetomidine is a selective α2 adrenergic receptor antagonist, which has little effect on respiratory suppression used as sedative agent. Also, dexmedetomidine has been reported to prolong the anesthesia time when used with patients undergoing spinal anesthesia. However, dexmedetomidine has sympathetic effect which can cause hypotension and bradycardia dose dependently. Therefore, this study is aimed to evaluate the effectiveness of premedication of anticholinergic agents on vital sign in patients undergoing spinal anesthesia.

Conditions

  • Bradycardia

Interventions

DRUG

Atropine

To evaluate the effectiveness of atropine on prevention bradycardia,atropine 0.01\~0.03mg/kg up to 0.5mg would be injected intravenously just before starting loading dose of dexmedetomidine in group A. During operation, heart rate decreasing 30% from initial heart rate or under 40/min would be regarded as bradycardia needing treatment, and atropine 0.5mg will be injected intravenously. This intervention would be applied to both group.

DRUG

Dexmedetomidine

Dexmedetomidine is a highly selective a2 adrenergic receptor antagonist used as sedative agent. After confirming the fixation level of spinal anesthesia, the loading dose(0.6ug/kg) of dexmedetomidine which is diluted with normal saline as 4ug/mL would be started for 10 minutes.Maintenance dose(0.25ug/kg/hr) would be continued after loading dose.

DRUG

Ephedrine

Systolic blood pressure decreasing 30% from basal blood pressure or under 90 mm Hg would be regarded as hypotension needing treatment, and ephedrine 5mg will be injected intravenously.
