[摘要] 目的 研究右美托咪定對腹腔鏡手術患者圍手術期血流動力學以及術后鎮靜評分的影響。 方法112例行腹腔鏡手術患者隨機平均分為研究組和對照組,對照組患者注射生理鹽水,研究組注射右美托咪定,比較兩組患者的麻醉效果及安全性。 結果 圍手術期研究組患者血流動力學指標的控制更好,術后24 h的鎮痛效果更佳,平均鎮痛時間和劑量更少,且兩組患者的不良反應之間的差異無統計學意義(P>0.05)。 結論 右美托咪定的使用可延長術后無痛期,降低總止痛需求,是腹腔鏡手術中理想的麻醉輔助劑。

[Abstract] Objective To study the effect of dexmedetomidine on perioperative hemodynamics parameters and postoperative sedation score in patients undergoing laparoscopic surgery. Methods A total of 112 patients underwent laparoscopic surgery were randomly average divided into study group and control group. Patients in the control group injected with saline, the study group given dexmedetomidine injected, the anesthesia effect and safety of the two groups of patients were compared. Results During the perioperative period, the study group had better control of hemodynamic parameters, the analgesic effect was better 24 h after operation, the average analgesic time and dose were less, there was no statistically significant difference between the two groups in adverse reactions(P>0.05). Conclusion The use of dexmedetomidine extends the postoperative painless period, reducing the total analgesic demand. It is an ideal anesthesia adjuvant in laparoscopic surgery.

腹腔鏡手術具有許多優點,如住院時間較短、手術后疼痛少等,目前受到廣泛的歡迎[1]。最近,印度市場上引入了新的α2激動劑右美托咪定。右美托咪定最初被允許用于重癥監護室鎮靜,但現在由于其獨特的性質,它通常用作麻醉輔助劑[2]。在麻醉實踐中已經成功地嘗試了右美托咪定的各種劑量和給藥途徑[3]。由于氣腹腹腔鏡手術,患者可能會發生各種病理生理變化。這些變化主要是全身和肺血管阻力升高,心率上升和心輸出量下降。腹腔鏡手術患者的位置也增加了進一步危及血液動力學的病理生理變化[4]。麻醉中的某些步驟如喉鏡檢查、插管和拔管也會引起交感神經系統的刺激,導致不可接受的血液動力學變化。臨……
