老年腹股沟疝患者在超声引导下髂腹下与髂腹股沟腹横肌平面阻滞的麻醉效果分析

目的探讨老年腹股沟疝患者应用超声引导下横肌平面阻滞（TAPB）联合髂腹下及髂腹股沟神经阻滞的临床效果。 方法选取2017年10月至2018年10月平罗县人民医院收治的老年腹股沟疝患者60例,采用随机数字表法将患者分为试验组和对照组,各30例,对照组行常规硬膜外麻醉,试验组行超声引导下TAPB联合髂腹下及髂腹股沟神经阻滞。比较2组手术相关临床参数、围手术期血流动力学变化,记录术后苏醒躁动及追加镇痛药情况,并进行患者躁动及疼痛的评估。 结果试验组术后苏醒时间短于对照组（P<0.05）;从手术麻醉前至手术结束,试验组患者心率（HR）、平均动脉压（MAP）、血氧饱和度（SpO₂）水平均无变化（P>0.05）,对照组患者HR、MAP水平在切皮前、切皮后10 min、手术结束时均高于手术麻醉前（P<0.05）;试验组患者在上述时间点的HR、MAP水平均低于对照组（P<0.05）;试验组苏醒躁动发生率、追加镇痛药发生率和Cravero评分均低于对照组（P<0.05）;试验组患者苏醒时,术后2、4、8 h的视觉模拟量表评分（VAS）均显著低于对照组（P<0.05）。 结论老年腹股沟疝患者应用超声引导下TAPB联合髂腹下及髂腹股沟神经阻滞可明显缩短苏醒时间,减少术后疼痛感,围手术期患者的血流动力学更稳定,且镇静效果好。     

超声定位与体表标志定位在儿童髂腹股沟-髂腹下神经阻滞中的比较：罗哌卡因血浆浓度测定的临床指导意义

背景儿童髂腹股沟-髂腹下神经阻滞常导致血浆局部麻醉药浓度过高。超声引导能为注射局麻药提供准确的解剖定位,从而影响局麻药的血浆浓度变化。为此,我们比较了超声定位与体表标志定位下行神经阻滞对罗哌卡因血浆浓度的影响。方法在全麻诱导下,将66例准备行腹股沟疝修补术的儿童随机分为两组,年龄为8个月-7岁,一组在超声定位下行髂腹股沟-髂腹下神经阻滞（n=35）,另一组在体表标志定位下行髂腹股沟-髂腹下神经阻滞（n=31）,均使用0．5％的罗哌卡因0．25ml／kg（1．25mg／kg）,分别在给药后0、5、10、20、30分钟用高效液相色谱法测罗哌卡因的血浆浓度,观察最大血浆浓度（Cmax）,达峰时间（tmax）,吸收率常数（ka）,在时间0分钟时血浆浓度的上升速度（dC0／d1）和曲线下面积值（AUC）。结果使用超声定位技术阻滞患儿的Cmax（sd）、ka、dC0／dt和AUC的值均高于使用标志定位技术的值,而tmax的值也短于使用标志定位技术的值。[Cmax：1．78（0．62）vs1．23（0．70）μg／ml,P〈0．01;ka：14．4（10．7）vs11．7（11．4）h^-1,P〈0．05;dC0／d1：0．26（0．12）vs0．15（0．03）μg·ml^-1·min^-1,P〈0．01;AUC：42．4（15．9）vs27．2（18．1）μg·30min^-1·ml^-1,P〈0．001;tmax：20．4（8．6）vs25．3（7．6）分钟,P〈0．05）。结论药物代谢动力学数据表明：与体表标志定位相比,在超声定位下行髂腹股沟-髂腹下神经阻滞局麻药的最大血浆浓度更高,药物吸收也更快。因此,在超声定位下行髂腹股沟-髂腹下神经阻滞时需要考虑减少局麻药的用量。

Pharmacokinetics and analgesic effect of ropivacaine following ilioinguinal/iliohypogastric nerve block in children

BACKGROUND: The aim was to investigate the efficacy, tolerance and pharmacokinetics of ropivavcaine when administered for ilioinguinal/iliohypogastric block in children. METHODS: We examined the pharmacokinetics and analgesic efficacy after ilioinguinal/iliohypogastric nerve block with 3 mg.kg-1 ropivacaine 5 mg.ml-1 in 22 children, aged 1-12 years, who were scheduled for inguinal surgery. Sixteen of 22 patients had a postoperative pain score < 4 (Objective Pain Scale). Nine children were given supplementary analgesics during the first six postoperative hours. RESULTS: The peak plasma concentration of total ropivacaine was 1.50 +/- 0.93 mg.l-1 (mean +/- SD) (range 0.64-4.77 mg.l-1) 15-64 min after the injection. The peak plasma concentration of free ropivacaine was 0.05 +/- 0.03 mg.l-1 (0.02-0.14 mg.l-1), which is well below the threshold for toxicity in adults. The terminal half-life was 2.0 +/- 0.7 h. No safety concerns or symptoms suggestive of systemic toxicity were observed. CONCLUSION: A dose of 3 mg.kg-1 of ropivacaine given as a single ilioinguinal/iliohypogastric nerve block in 1-12-year-old children provides satisfactory postoperative pain relief, and is well tolerated.

Ultrasonography for ilioinguinal/iliohypogastric nerve blocks in children

Background. The ilioinguinal/iliohypogastric nerve block isa popular regional anaesthetic technique for children undergoinginguinal surgery. The success rate is only 70–80% andcomplications may occur. A prospective randomized double-blindedstudy was designed to compare the use of ultrasonography withthe conventional ilioinguinal/iliohypogastric nerve block technique. Methods. One hundred children (age range, 1 month–8 years)scheduled for inguinal hernia repair, orchidopexy or hydrocelerepair were included in the study. Following induction of generalanaesthesia, the children received an ilioinguinal/iliohypogastricblock performed either under ultrasound guidance using levobupivacaine0.25% until both nerves were surrounded by the local anaestheticor by the conventional ‘fascial click’ method usinglevobupivacaine 0.25% (0.3 ml kg^–1). Additional intra-and postoperative analgesic requirements were recorded. Results. Ultrasonographic visualization of the ilioinguinal/iliohypogastricnerves was possible in all cases. The amount of local anaestheticused in the ultrasound group was significantly lower than inthe ‘fascial click’ group (0.19 (SD 0.05) ml kg^–1vs 0.3 ml kg^–1, P<0.0001). During the intraoperativeperiod 4% of the children in the ultrasound group received additionalanalgesics compared with 26% in the fascial click group (P=0.004).Only three children (6%) in the ultrasound-guided group neededpostoperative rectal acetaminophen compared with 20 children(40%) in the fascial click group (P<0.0001). Conclusions. Ultrasound-guided ilioinguinal/iliohypogastricnerve blocks can be achieved with significantly smaller volumesof local anaesthetics. The intra- and postoperative requirementsfor additional analgesia are significantly lower than with theconventional method.      

Iliac compartment block following ilioinguinal iliohypogastric nerve block

Transient femoral nerve palsy is a known complication associated with percutaneous ilioinguinal iliohypogastric nerve block. Excess volume and higher concentrations of local anesthetic have been implicated for transient femoral nerve palsy. We encountered partial iliac compartment block involving lateral cutaneous nerve of the thigh and femoral nerve with a lower concentration (0.25%) of bupivacaine administered in the smallest indicated volume of 0.25 ml.kg-1 using a double-shot technique.     

Anatomical considerations of the pediatric ilioinguinal/iliohypogastric nerve block

BACKGROUND: The ilioinguinal/iliohypogastric nerve block is safe, effective and easy to perform in order to provide analgesia for a variety of inguinal surgical procedures in pediatric patients. A relatively high failure rate of 10-25% has been reported, even in experienced hands. The aim of this study was to determine the exact anatomical position of the ilioinguinal and iliohypogastric nerves in relation to an easily identifiable constant bony landmark, the anterior superior iliac spine (ASIS) in neonates and infants. The current ilioinguinal/iliohypogastric nerve block techniques were also evaluated from an anatomical perspective. METHOD: Dissections were performed on a sample of 25 infant and neonatal cadavers (mean weight = 2.2 kg; mean height = 45.6 cm). The distance from the ASIS to both the ilioinguinal and iliohypogastric nerves, on a line connecting the ASIS to the umbilicus was carefully measured using a digital caliper. Three techniques, commonly used in clinical practice, were simulated on the anatomical specimens. RESULT: The left and right ilioinguinal nerves were closer to the ASIS than previously described, i.e. 1.9 +/- 0.9 mm (mean +/- sd) and 2.0 +/- 0.7 mm, respectively. The mean distance from the left and right iliohypogastric nerves to the ASIS are 3.3 +/- 0.8 mm and 3.9 +/- 1.0 mm, respectively. CONCLUSIONS: We suggest that the high failure rate of the ilioinguinal/iliohypogastric nerve block in this age group could be due to lack of specific spatial knowledge of the anatomy of these nerves in infants and neonates. This cadaver-based study suggests an insertion point closer to the ASIS, approximately 2.5 mm (range: 1.0-4.9) from the ASIS on a line drawn between the ipsilateral ASIS and the umbilicus.     

右美托咪定联合不同浓度罗哌卡因局部神经阻滞在老年腹股沟疝无张力修补术中的应用

目的分析右美托咪定联合不同浓度罗哌卡因局部神经阻滞在老年腹股沟疝无张力修补术中的应用。 方法2020年3月至2022年3月内蒙古包钢医院收治的老年腹股沟疝患者80例,采用随机数字表法分为A组与B组,各40例。2组均接受无张力疝修补术治疗,A组接受0.1%罗哌卡因局部神经阻滞联合右美托咪定静脉泵入麻醉,B组采用0.2%罗哌卡因局部神经阻滞联合右美托咪定静脉泵入麻醉,术后均观察7 d。分析2组不同时间点生命体征,术后2 h、24 h疼痛、镇静、运动及认知评分,术前、术后7 d 2组血清Tau蛋白、β-淀粉样蛋白多肽42（Aβ42）蛋白以及Tau/Aβ42水平,术后24 h不良反应发生情况。 结果切皮时（T2）B组心率低于入室（T0）、阻滞后15 min（T1）及手术结束时（T3）,且低于A组（P<0.05）,其余时刻心率、平均动脉压、脉搏血氧饱和度比较,差异无统计学意义（P>0.05）。与术后2 h比较,术后24 h 2组视觉模拟评分（VAS）、Bromage评分均降低,且A组VAS评分在2组中更低（P<0.05）;术后24 h 2组简易智力状态检查量表（MMSE）评分均升高,且A组在2组中更高（P<0.05）。与术前比较,术后7 d 2组血清Tau蛋白、Tau/Aβ42水平均升高,但A组较B组更低;术后7 d 2组血清Aβ42蛋白降低,但A组较B组更高（P<0.05）。术后24 h,A组不良反应发生率较B组更低（7.50% vs 27.50%,P<0.05）。 结论0.1%罗哌卡因局部神经阻滞联合右美托咪定静脉泵入麻醉可稳定老年腹股沟疝无张力修补术患者生命体征,缓解疼痛,改善患者认知功能,安全性更高,分析与其调节Tau蛋白、Aβ42蛋白水平有关,值得临床进一步研究。     

Evaluation of genitofemoral nerve block, in addition to ilioinguinal and iliohypogastric nerve block, during inguinal hernia repair in children

Background. Ilioinguinal and iliohypogastric (IG-IH) nerve blockhas been widely used in children undergoing inguinal herniarepair. This technique may provide insufficient analgesia forintraoperative management as the inguinal region may receivesensory innervation from genitofemoral nerve. We proposed thataddition of a genitofemoral nerve block might improve the qualityof analgesia. Methods. Ninety-eight children undergoing inguinal hernia repairwere assigned randomly to receive either IG-IH nerve block (GroupI) or IG-IH and genitofemoral nerve blocks (Group II). Systolicarterial pressure (SAP) and heart rate (HR) were recorded beforesurgery (control), after skin incision, at sac traction andat the end of surgery. Postoperative analgesic requirementsand incidence of complications were recorded until discharge. Results. At sac traction, SAP and HR were significantly higherin Group I (P<0.05), and the incidence of episodes of increasedHR was also significantly higher in Group II (29 vs 12%, respectively,P<0.05). There were no significant differences in SAP andHR at other time points, postoperative analgesic requirementsor incidence of complications between the groups. Conclusions. The benefit of the additional genitofemoral nerveblock to IG-IH nerve block was limited only to the time of sactraction without any postoperative effect. This suggests thereis little clinical benefit in the addition of a genitofemoralnerve block.
