[摘要] 目的 探討超聲引導腹壁神經阻滯聯合右美托咪定在腹膜透析置管術中的安全性與有效性。 方法 選取2018年5月至2019年3月我院終末期腎臟病擇期行腹膜透析置管術患者60例，ASA Ⅲ～Ⅳ，年齡19～69歲，體重45～80 kg，隨機分為三組（n=20）：局部浸潤阻滯組（L組）、超聲引導腹橫肌平面阻滯聯合腹直肌鞘阻滯組（TR組）、超聲引導腹壁神經阻滯聯合右美托咪定組（TRD組）。觀察三組患者入室（T1）、切皮（T2）、分離（T3）、探查（T4）、置管（T5）、縫皮（T6）和出室（T7）各時點平均動脈壓（MAP）、心率（HR）和視覺模擬疼痛評分（VAS）、手術時間、術后24 h靜息/運動VAS評分、患者滿意度、醫(yī)生滿意度及麻醉相關并發(fā)癥。 結果 與L組比較，TR組患者T3～T5時點MAP明顯降低（P<0.05），T2～T7時點HR明顯下降（P<0.05），T3～T6時點VAS評分明顯下降（P<0.05），手術時間明顯縮短（t=3.680，P=0.001），術后2 h、6 h、12 h和24 h靜息/運動VAS評分均明顯降低（P<0.05），患者滿意度和醫(yī)生滿意度明顯升高（Z=3.351，P=0.001;Z=5.213，P<0.05）;與L組比較，TRD組患者T2～T7 時點MAP和HR明顯降低（P<0.05），手術時間明顯縮短（t=3.250，P=0.002），T2～T6 VAS評分均明顯降低（P<0.05），患者滿意度和醫(yī)生滿意度明顯升高（Z=4.528，P<0.05;Z=5.213，P<0.05）;與TR組比較，TRD組患者T2 VAS評分明顯降低（Z=2.670，P=0.007），T4～T7時點MAP明顯下降（t=2.100，P=0.043;t=2.270，P=0.029;t=2.540，P=0.015;t=2.110，P=0.041），T6和T7時點HR明顯下降（t=2.450，P=0.019;t=2.150，P=0.038），患者滿意度明顯升高（Z=2.047，P=0.041）;三組患者均未發(fā)生麻醉相關并發(fā)癥。結論 超聲引導腹壁神經阻滯聯合右美托咪定用于腹膜透析置管術安全且麻醉鎮(zhèn)痛更完善，術中血流動力學波動小，術后鎮(zhèn)痛效果較好，患者滿意度高，是腹膜透析置管術更為理想的麻醉選擇。

[Abstract] Objective To investigate the safety and effectiveness of ultrasound-guided abdominal wall nerve block combined with dexmedetomidine in peritoneal dialysis catheterization. Methods A total of 60 end-stage renal disease patients with ASA Ⅲ-Ⅳ， 19-69 years old， 45-80 kg who underwent selective peritoneal dialysis in our hospital from May 2018 to March 2019 were randomly divided into three groups （n=20）：local infiltration block group （L group）， ultrasound guided transverse abdominal muscle plane block combined with rectus sheath block （TR group）， ultrasound guided abdominal wall nerve block combined with dexmedetomidine group （TRD group）. The mean arterial pressure （MAP）， heart rate （HR）and visual analog pain score （VAS）， operation time， 24 h rest/exercise VAS score after surgery， patient satisfaction， doctor satisfaction， and anesthesia-related complications when When entering the room （T1）， cutting the skin （T2）， separating （T3）， exploring （T4）， placing the tube （T5）， suturing the skin （T6） and leaving the room （T7） of the three groups were observed. Results Compared with that of the L group， the MAP of patients in the TR group was significantly lower at T3-T5 （P<0.05）; the HR decreased substantially at T2-T7 （P<0.05）; the VAS score at T3-T6 decreased significantly （P<0.05）; the operation time was significantly shortened （t=3.680， P=0.001）; the rest/exercise VAS scores of 2 h， 6 h， 12 h and 24 h after operation were significantly reduced （P<0.05）; the patient satisfaction and doctor satisfaction were increased considerably （Z=3.351， P=0.001; Z=5.213， P<0.05）. Compared with that of the L group， the MAP and HR of patients in the TRD group at T2-T7 was significantly lower （P<0.05）， and the operation time was shortened obviously （t=3.250， P=0.002）， the intraoperative VAS score was significantly reduced at T2-T6 （P<0.05）， and patient satisfaction and doctor satisfaction was increased considerably （Z=4.528， P<0.05; Z=5.213， P<0.05）. Compared with that of the TR group， the T2 VAS score of the TRD group was significantly reduced （Z=2.670， P=0.007）; the MAP at T4-T7 was significantly decreased （t=2.100， P=0.043; t=2.270， P=0.029; t=2.540， P=0.015; t=2.110， P=0.041）; the HR at T6-T7 decreased significantly （t=2.450， P=0.019; t=2.150， P=0.038）; patient satisfaction at T6-T7 was significantly increased （Z=2.047， P=0.041）. No anesthesia-related complications occurred in the three groups. Conclusion Ultrasound-guided abdominal wall nerve block combined with dexmedetomidine is safe and more perfect for peritoneal dialysis catheterization， with small fluctuations of hemodynamics， better postoperative analgesia， and high patient satisfaction. It is an ideal anesthesia choice for peritoneal dialysis catheterization.
