Abstract:
Objective To investigate the effect of small dose of dexmedetornidine on venous continuous infusion combined with oxycodone or fentanyl during brachial plexus blockade.Methods Sixty thyroid patients (ASA Ⅰ or Ⅱ) undergone brachial plexus anesthesia for cutting or cutting thyroid tumor patients were randomly and double-blindly into three groups (n =20 in each group).Group A:single brachial plexus anesthesia;group B:dexmedetornidine combined with fentanyl;group C:dexmedetornidine combined with oxycodone.Blood pressure (Bp),heart rate (HR),the determination of plasma norepinephrine (NE),cortisol (Cor),the concentration of blood glucose (Glu),VAS,Ramsay calm score,local anesthetics dosage and side effect formation rate at the beginning operation (To),skin incision (T1),separation of the glands (T2),gland excision (T3),and the end of the surgery (T4) were recorded.Results Compared to group A,the mean arterial pressure (MAP),HR,NE,Cor,and Glu were much lower at each time point (P ＜ 0.05) in groups B and C;Ramsay calm score and VAS score were significantly better at each time point (P ＜ 0.05);the incidence of chills and lidocaine additional quantity were significantly lower (P ＜0.01).However,compared to groups A and C,choking cough response rates were much higher in group B (P ＜ 0.01).Conclusions Small dose of dexmedetornidine on venous continuous infusion combined with oxycodone during brachial plexus blockade for thyroid patients both can eliminate the preoperative patients nervous anxiety,and effectively restrain perioperative stress response,maintain hemodynamics stable,implementation of intraoperative awaken to reduce complications.It is the new choice of anesthetic adjuvant.
