布托啡诺预先给药对大鼠心肌缺血再灌注损伤的影响

目的 探讨布托啡诺预先给药对大鼠心肌缺血再灌注损伤的影响.方法 健康雄性SD大鼠40只,体重200～250 g,随机分为5组,每组8只.假手术组(S组)开胸暴露心脏,左冠状动脉前降支仅穿线但不结扎;缺血再灌注组(IR组)结扎左冠状动脉前降支30 min,再灌注120 min;S组和IR组于缺血前10 min经股静脉注射生理盐水5ml/kg,随后以5 ml·kg-1·h-1的速率静脉输注;布托啡诺预先给药组(B组)缺血前10 min经股静脉注射布托啡诺25μg/kg,余处理同IR组;Nor-BNI组(N组)缺血前20 min经股静脉注射选择性K受体阻断剂Nor-BNI 2 mg/kg,余处理同B组;格列本脲组(G组)缺血前10 min经股静脉注射KATP通道阻滞剂格列本脲1 mg/kg,余处理同B组.于再灌注120 min时取股动脉血样,采用ELISA法测定血清肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)和IL-10的浓度;采用TTC染色法测定心肌梗死区及心肌缺血区,计算心肌梗死面积.结果 与S组比较,其余各组血清TNF-α、IL-6和IL-10浓度升高(P<0.05);与IR组比较,B组、N组和G组血清TNF-α、IL-6浓度降低,IL-10浓度升高,心肌梗死面积减小(P<0.05);与B组比较,N组和G组血清TNF-α、IL-6浓度升高,IL-10浓度降低,心肌梗死面积增加(P<0.05).结论 布托啡诺预先给药可减轻大鼠心肌缺血再灌注损伤,可能与激活κ受体和KATP通道有关.     

布托啡诺预先给药对大鼠心肌缺血再灌注损伤的影响

Objective To investigate the effects of butorphanol pretreatment on myocardial ischemia-reperfusion (IR) injury in rats. Methods Forty healthy male SD rats weighing 200-250 g were randomly divided into 5 groups (n = 8 each) : sham operation group (group S); IR group; butorphanol pretreatment group (group B); Nor-BNI group (group N) and glibenclamide group (group G) . In group IR, B, N and G, myocardial IR was produced by occlusion of left anterior descending artery (LAD) for 30 min followed by 120 min reperfusion. In group S and IR, normal saline S ml/kg was injected via femoral vein 10 min before ischemia and then continuously infused at a rate of 5 ml· kg -1· h-1 iv. In group B, butorphanol 25 μg/kg was injected via femoral vein 10 min before ischemia and the rest method was the same as that described in group IR. In group N, Nor-BNI 2 mg/kg (a selective κ-opioid receptor antagonist) was injected via femoral vein 20 min before ischemia and the rest method was the same as that described in group B. In group G, glibenclamide 1 mg/kg (a KATP channel blocker) was injected via femoral vein 10 min before ischemia and the rest method was the same as that described in group B. Blood samples were taken from femoral artery at 120 min of reperfusion for determination of the concentrations of serum TNF-α, IL-6 and IL-10 by ELISA. Myocardial infarct area and ischemic area were measured by TTC staining and myocardial infarct size was calculated. Results The concentrations of serum TNF-a, IL-6 and IL-10 were significantly higher in the other four groups than in group S (P < 0.05) . The concentrations of serum TNF-α andIL-6 were significantly decreased while IL-10 increased, and the myocardial infarct size was significantly decreased in group B, N and G as compared with group IR ( P < 0.05) . The concentrations of serum TNF-α and IL-6 were significantly increased while the concentration of IL-10 decreased) and the myocardial infarct size was significantly increased in group N and G as compared with group B ( P < 0.05). Conclusion Butorphanol pretreatment can protect the myocardium against IR injury in rate via activating κ receptor and KATP channel.

目的 探讨布托啡诺对福尔马林致痛大鼠脊髓Fos蛋白表达的影响.方法 SD大鼠25只,随机分为5组(n=5):生理盐水组(NS组)、福尔马林组(F组)、芬太尼-福尔马林组(FF组)、布托啡诺-福尔马林Ⅰ组(BF1,组)和布托啡诺-福尔马林Ⅱ组(BF2组).NS组和F组腹腔注射0.9%生理盐水500μl,FF组、BF1组和BF2组分别腹腔注射0.1 ms/kg芬太尼、1 mg/kg布托啡诺和2mg/kg布托啡诺,药物均用生理盐水稀释至500μl,5 min后NS组右侧后肢跖部皮下注射生理盐水150μl,其余各组均注射4%福尔马林15μl.于注射福尔马林后5、lO、20、30、45、60、90、120 min时记录痛行为学评分;注射布托啡诺后2 h时处死大鼠,取L3～L5段脊髓,采用免疫组化法测定脊髓Fos蛋白表达水平.结果 与NS组比较,其余各组痛行为学评分升高,脊髓Fos蛋白表达上调(P<0.05);与F组比较,FF组、BF1组和BF2组痛行为学评分降低,脊髓Fos蛋白表达下调(P<0.05);与FF组比较,BF1组痛行为学评分升高,脊髓Fos蛋白表达上调(P<0.05),BF2组差异无统计学意义(P>0.05);与BF1组比较,BF2组痛行为学评分降低,脊髓Fos蛋白表达下调(P<0.05).结论 布托啡诺可减轻大鼠福尔马林致痛程度,其机制与抑制脊髓Fos蛋白表达上调有关,其效应呈剂量依赖性.     

布托啡诺硬膜外术后镇痛对胃肠动力的影响

阿片受体激动拮抗药布托啡诺主要激动κ受体发挥镇痛作用,对μ受体有弱拮抗作用,用作硬膜外术后镇痛对胃肠道功能影响文献报道不多.本研究观察并比较布托啡诺与吗啡用作胆囊切除术后硬膜外镇痛对病人胃肠道功能恢复的影响,选择更有利于病人术后恢复的镇痛药配方.[第一段]     

不同剂量布托啡诺用于乳房肿块切除术后的镇痛效果和不良反应

布托啡诺是一种新合成的阿片受体激动-拮抗药[1],主要通过作用于κ受体产生镇痛效应,对于μ、δ受体的作用甚微。乳房肿块切除术虽然是一短小手术,但术后仍有中度疼痛。本研究旨在观察布托啡诺用于乳房肿块切除术后的镇痛效果及不良反应,寻找布托啡诺用于乳房肿块切除术后镇痛的合适剂量。资料与方法一般资料选择择期行乳房肿块切除术的女性患者120例,ASAⅠ或Ⅱ级,年龄18~60岁,体重40~70kg,术前未使用地西泮、吗啡等镇静镇痛药,随机分为布托啡诺1、2、3组(B1、B2、B3组)和对照组(C组),每组30例。麻醉方法麻醉前30min肌注苯巴比妥钠0.1g、…     

布托啡诺在术后镇痛的应用

目的观察布托啡诺用于术后镇痛的效果。方法105例硬膜外麻醉术后患者随机均分为芬太尼镇痛组（Ⅰ组）,曲马多镇痛组（Ⅱ组）和布托啡诺镇痛组（Ⅲ组）,比较术后镇痛效果和副作用。结果三组均获得了满意的术后镇痛效果。其中Ⅰ组术后4h VAS和术后24h D1／D2值分别小于Ⅱ组（P〈0．05）。头痛头晕Ⅱ组多于Ⅰ组（P〈0．05）。排尿困难Ⅲ组少于Ⅰ组（P〈0．05）。OAA／S评分Ⅲ组分别大于Ⅰ组和Ⅱ组（P〈0．05或P〈0．01）。结论布托啡诺在下腹部和下肢手术是一种有效术后镇痛药物,副作用较少,但嗜睡副作用应引起高度重视。     

酒石酸布托啡诺对舒芬太尼诱发咳嗽反射的影响

目的观察酒石酸布托啡诺对舒芬太尼诱发咳嗽反射的影响。 方法择期行腹腔镜胆囊切除术患者82例,ASAⅠ或Ⅱ级,随机分为两组,分别于麻醉诱导前静注以生理盐水稀释至5 ml的酒石酸布托啡诺1 mg (试验组)或生理盐水5 ml(对照组),5 min后在3 s内静注舒芬太尼0.3 μg/kg,观察并记录两组患者2 min内咳嗽反射的发生率和强度。 结果试验组患者咳嗽反射的发生率、强度明显低于对照组。 结论酒石酸布托啡诺1 mg可以抑制舒芬太尼诱发的咳嗽反射。     

布托啡诺对瑞芬太尼麻醉后痛觉过敏的预防

瑞芬太尼是新型的超短效μ阿片受体激动药,目前广泛应用于全麻手术中。但临床证实大剂量或长时间使用会诱发痛觉过敏。布托啡诺是κ阿片受体激动药,对μ受体有拮抗作用。本研究观察布托啡诺是否能有效地抑制瑞芬太尼停药后的痛觉过敏现象。资料与方法一般资料选择腹腔镜下胆道手术患者75例,ASAⅠ或Ⅱ级,年龄38～59岁,体重48～86 kg,随机均分为三组,分别泵注瑞芬太尼0.1μg·kg^-1·min^-1组（R₁组）、0.4μg·kg^-1·min^-1（R₂组）、0.4μg·kg^-1·min^-1和布托啡诺（批号:H20020454,江苏恒瑞医药公司）0.02 mg/kg组(B     

不同剂量布托啡诺对胃癌根治术后患者静脉自控镇痛效能的比较

目的观察不同剂量的布托啡诺对胃癌根治术后患者静脉自控镇痛效能的比较。方法选择行胃癌根治的患者232例,ASA为Ⅰ～Ⅱ级。将232例患者随机分为布托啡诺静脉自控镇痛组和对照组,每组均为29例。其中布托啡诺组分为6个小组,分别是布托啡诺浓度为0.004%、0.005%、0.006%、0.007%、0.008%和0.009%的A1、A2、A3、A4、A5和A6组。对照组分为2个小组,分别是吗啡浓度为0.025%的B1组以及传统方法治疗B2组。在胃癌根治术后1d观察患者情况,详细记录患者的舒适度评分、镇静度评分、视觉模拟评分以及患者的不良反应与PCIA的总按压频率次数和实际用药情况。结果①A3～A6组以及B1组的VAS评分明显低于B2和A1、A2组,而BCS的评分要高于B2和A1、A2组（P〈0.05）。②A3～A6组的PCIA总压次数明显低于A1、A2组,然而用药量远远高于A1、A2两组（P〈0.05）。③B1组患者腹胀、恶心、呕吐等不良症状发生频率远远高于A1～A6以及B2组患者（P〈0.05）。A6组患者的嗜睡程度最高。A1、A2组需要其他镇痛药物辅助,镇痛效果才能达到A3～A6组。结论布托啡诺的浓度为0.006%、0.007%时,以0.0022～0.0026mg/（kg.h）的速率给药,负荷剂量为0.005mg/（kg.h）的静脉PCIA会获得最佳的镇痛疗效,并且不良反应的发生率极低,可以应用于相关临床疾病的治疗中。

目的 观察硬膜外注射不同剂量的酒石酸布托啡诺(布托啡诺)对大鼠血清髓鞘碱性蛋白(myelin basic protein,MBP)和脊髓形态学的影响.方法 雄性SD大鼠,体重180 g～210 g,于L1-2处行硬膜外置入PE-530导管,3d后,取无运动障碍的大鼠32只,随机数字表法分为4组(每组8例):生理盐水组(...     

酒石酸布托啡诺镇痛专家共识

疼痛的危害及术后镇痛的必要性疼痛是组织损伤或潜在组织损伤所引起的不愉快感觉和情感体验。急性疼痛常与手术创伤、组织损伤或某些疾病状态有关,持续时间通常短于1个月。术后疼痛(postoperative pain),是手术后即刻发生的急性疼痛(通常持续不超过7 d),其性质为伤害性疼痛,也是临床最常见和最需紧急处理的急性疼痛。术后痛可能导致机
