目的 比较超声引导下胸壁神经阻滞［胸横肌平面-胸神经阻滞(transversus thoracic muscle plane-pectoral nerves,TTP-PECS)］与胸椎旁神经阻滞(thoracic paravertebral block,TPVB)用于乳腺癌改良根治术围术期的镇痛效果与安全性。
方法 择期行乳腺癌改良根治术的女性患者64例,年龄35～72岁,BMI 20～26 kg/m2,ASA Ⅰ或Ⅱ级。所有患者随机均分为两组:TTP-PECS组(A组)和TPVB组(B组)。麻醉诱导前A组在超声引导下行患侧TTP-PECS,B组在超声引导下行患侧TPVB,均注入0.5％罗哌卡因30 ml,分别于操作结束后30 min测定痛觉减退范围。术毕两组患者均给予PCIA,并静注氟比洛芬酯50 mg补救镇痛,维持静息VAS评分≤3分或运动VAS评分≤5分。记录神经阻滞操作时间、阻滞范围、阻滞相关并发症的发生情况;记录术中芬太尼消耗量、阻滞镇痛维持时间、镇痛泵有效按压次数及补救镇痛例数;评估术后2、6、12、24及48 h的静息及运动状态下的VAS评分;记录术中血管活性药物使用量、术后不良反应的发生情况。
结果 A组阻滞范围主要为T2—T6,B组主要为T3—T7,A组T2皮区的阻滞者明显多于B组,T6、T7皮区的阻滞者少于B组(P<0.05);与B组比较,A组阻滞操作时间缩短,阻滞镇痛时间延长,镇痛泵有效按压次数和补救镇痛例数明显减少,术后12 h的VAS评分明显降低(P<0.05);A组术中血管活性药物使用量明显减少,术后低血压和心动过缓发生率明显低于B组(P<0.05)。
结论 超声引导下TTP-PECS用于乳腺癌改良根治术的围术期镇痛效果和安全性优于TPVB。 |

Objective To campare the perioperative analgesia effect between ultrasound-guided thoracic wall nerve block (TTP-PECS)and thoracic paravertebral block (TPVB)in patients undergoing modified radical mastectomy.
Methods Sixty-four patients, aged 35-72 yr, with a BMI 20-26 kg/m2, falling into ASA physical status Ⅰ or Ⅱ category, scheduled for elective modified radical mastectomy were randomly divided into thoracic wall nerve block group (group A) and thoracic paravertebral block group (group B). Before general anesthesia induction, TTP-PECS and TPVB were performed with 0.5％ ropivacaine 30 ml respectively. 30 min after block, the range of sensory block was assessed. Patient-controlled intravenous analgesia (PCIA) was provided to all the patients in both groups when the operation was over. Flurbiprofen 50 mg was injected intravenously as a rescue analgesic to maintain the VAS score less than 3 at quiescence or less than 5 at motion. Time-consuming, area-blocking, adverse reaction of each nerve block were recored. Fentanil consumption, analgesia duration, the effective pressing times of PCA pump and cases of remedial analgesia were also recorded;VAS scores at quiescence and at motion were evaluated at 2, 6, 12, 24 and 48 h after operation. Meanwhile, the intraoperative usage of vasoactive agents were recorded, as well as the postoperative adverse reactions.
Results The main blocking area was T2-T6 in group A and T3-T7 in group B, T2 dermatomal spread was significantly increased but T6and T7 dermatomal spread decreased in group A (P<0.05). Compared with group B, the nerve block time-consuming was shorter, the duration of block analgesia was longer, the effective pressing times and postoperative remedial analgesia cases were reduced, the 12 h postoperative VAS scores of quiescence and motion were lowered in group A(P<0.05). In group A, the usage of vasoactive agents and the incidence of postoperative hypotension and bradycardia were decreased (P<0.05).
Conclusion Ultrasound-guided thoracic wall nerve block can provide better perioperative analgesia effect and security than ultrasound-guided thoracic paravertebral block in patients undergoing modified radical mastectomy. |
