Evaluation of dexmedetomidine combining with sufentanyl for vein analgesia after laryngeal carcinoma surgery / 实用医学杂志

ABSTRACT

Objective To investigate the effectiveness and safety of dexmedetomidine combining with sufentanyl in controlling PCIA after laryngeal carcinoma surgery. Methods One hundred laryngeal carcinoma patients (ASAⅠorⅡ) were randomly assigned into 2 groups (n = 50, in each group). Group SF sufentanil 0.04 mg/(kg·h)+dolasetron 12.5 mg; Group DE dexmedetomidine 0.1 mg/(kg·h) +sufentani 0.02 mg/(kg· h) +dolasetron 12.5 mg, in which all drugs were dissolved in 100 mL 0.9% normal saline. Parameters Infusion speed 2 mL/h; PCIA dosage 0.5 mL each time; monitor time 15 min. PCIA were administrated after anesthesia recovery; BP, HR, SpO2, RR, RPP, pain and sedation score, side effect formation rate at 4、12、24、48 h after surgery were also recorded. Results MAP, RPP and HR in group DE were significant decreased compared with group SF at each time point,(P 0.05); Ramsay calm scores in group DE were significant better than that in group SF at each time point after surgery (P < 0.05); Frequency of nausea,vomiting and chills in group DE were significant lower than those in group SF (P < 0.05). Conclusion Small dose dexmedetomidine combination with sufentanil administration in PCIA after laryngeal carcinoma surgery could acquire satisfied analgesic effect , also could eliminate the patient anxious mood , enhance the security in the perioperative period and improve the patients' satisfaction degree , whichis very suitable for multi mode analgesia acquirement.
