研究目的:

主要研究目的:评估基于PVB的无阿片类药物全麻应用于小儿侧切口体外循环心脏手术是否可减少术后24小时阿片类药物用量。 次要研究目的:与传统小剂量阿片类药物麻醉的FTCA患儿相比,评估基于PVB的无阿片类药物全麻能否达到同样的镇痛效果。 探索性研究目的:(1)评估基于PVB的无阿片类药物全麻应用于小儿侧切口体外循环手术中的血流动力学稳定性以及能否有效控制CPB心脏手术中的应激和炎症反应。(2)与传统小剂量阿片类药物麻醉的FTCA患儿相比,评估基于PVB的无阿片类药物全麻术后阿片类药物并发症发生率是否更低,有无术后其他麻醉相关并发症,是否增加术后带气管插管时间、术后ICU停留时间、术后住院时间。  

Objectives of Study:

primary hypothesis: compared with FTCA children under traditional low-dose opioid anesthesia, PVB based opioid free general anesthesia used in pediatric thoracotomic cardiopulmonary bypass surgery can reduce the opioids consumption within 24 hours after operation. secondary hypotheses: compared with FTCA children under traditional low-dose opioid anesthesia, PVB based opioid free general anesthesia can achieve the same perioperative stress response and inflammatory level, and the intraoperative hemodynamics can be stable. And other secondary hypotheses: compared with FTCA children under traditional low-dose opioid anesthesia, PVB based opioid free general anesthesia can achieve the same analgesic effect, with lower incidence of postoperative complications (low incidence of postoperative nausea and vomiting, no opioid complications such as postoperative respiratory depression), and no other postoperative anesthesia related complications. The postoperative mechanical ventilation time, postoperative ICU stay and postoperative hospital stay would not increase by using the PVB based opioid free general anesthesia.

药物成份或治疗方案详述:

两组均无术前用药,入室后采用吸入6~8%七氟烷使患儿入睡,然后行外周静脉穿刺,静脉开放后,经静脉给予地塞米松(0.3 mg/kg,最大5mg)、咪达唑仑(0.1 mg/kg)、顺式阿曲库铵(0.2 mg/kg)、盐酸戊乙奎醚(0.02 mg/kg)、酮铬酸氨丁三醇(0.5 mg/kg)、利多卡因(1 mg/kg)行麻醉诱导,经口插入合适型号的带囊气管导管。麻醉维持采用静脉持续泵注右美托咪定(1 μg/kg/h)、顺式阿曲库铵(0.2 mg/kg/h),异丙酚(1~4 mg/kg/h),吸入七氟烷(1~3%)。 试验组患儿经口气管插管后,患儿置于左侧卧位,行超声引导下右T4椎旁神经阻滞。推荐采用矢状位平面内进针法:患儿取左侧卧位,低头弓背,消毒铺单后,在超声引导下进行穿刺,选择手术侧 T4 棘突下缘为穿刺点,于术侧脊柱旁开约2.5cm 处放置超声探头,探头方向平行于脊柱,垂直于皮肤,调整探头位置直至可以分辨从上到下的肋横突上韧带、胸膜,从而找到椎旁间隙,确定位置后在超声引导下进针,使其依次穿过皮肤、肋间外肌、肋间内膜,直至椎旁间隙,回抽无血、无脑脊液后,注入 0.3%罗哌卡因,总量0.8~1 mL/kg(即罗哌卡因总量为2.4~3 mg /kg),注入后可见胸膜下压。也可以采用其他方法,如矢状位平面外进针法、水平位(肋间)平面内或平面外进针法等。对照组患儿不进行椎旁神经阻滞,为遵从盲法原则,在椎旁阻滞穿刺相似位置,消毒后用针头刺破皮肤并贴膜。 所有患儿均在麻醉诱导后留置动脉及中心静脉导管,连续监测有创动脉和中心静脉压力,术中常规监测心电图、脉搏血氧饱和度、鼻咽温、肛温和尿量。 所有患儿均于左侧卧位采用低温体外循环(Cardiopulmonary bypass, CPB)下行右侧切口直视修补手术。术中予以全量肝素化,试验组椎旁阻滞完成后一小时再静脉全量肝素化,保持激活全血凝固时间大于410秒,阻断升主动脉后灌注心肌停跳液使心脏停跳,开放升主动脉后根据临床需求持续泵入血管活性药物辅助心脏功能。CPB期间常规超滤维持Hb > 70 g/L,停CPB后采用改良超滤使血红蛋白至100 g/L左右。改良超滤后给予鱼精蛋白中和肝素。所有患者术后均转入ICU。 对照组患儿在切皮前和主动脉插管前分别静脉注射舒芬太尼0.5 μg/kg;试验组患儿手术期间不使用阿片类药物。根据患者镇静深度及血流动力学变化,调节七氟烷吸入浓度及异丙酚用量。 手术结束后对照组患儿于手术切口及引流管放置处采用0.3%罗哌卡因0.33~0.66 mL/kg(即1~2 mg/kg)行切口及引流管口皮下浸润麻醉。试验组不行皮下浸润麻醉。 椎旁神经阻滞失败补救方法:如果切皮后试验组患儿动脉血压波动大于基线值20%则说明椎旁神经阻滞失败,则适量使用舒芬太尼(总量≤1 μg/kg),调节七氟烷吸入浓度及异丙酚用量,确保患者的动脉血压在切开胸骨之后波动范围在基线血压值的20%之内,以保证患儿循环稳定。体外循环期间予以持续静脉泵注异丙酚(0.2~5 mg/kg/h)、右美托咪定(1 μg/kg/h),吸入七氟烷(1~3%)维持麻醉深度,体外循环开始时停止泵入顺式阿曲库铵。 患儿手术过程中未出现手术时间过长,术后未出现外科出血以及手术意外导致心功能差等早拔管禁忌证,待患儿术后自主呼吸恢复、血流动力学稳定后,由麻醉医师或重症监护室医师尽早拔出气管插管。患者满足以下拔管条件即可拔出气管插管:(1)自主呼吸恢复(潮气量大于5 mL/kg,呼吸均匀,呼吸频率小于40次/分,并能维持呼吸末二氧化碳低于50 mmHg,在吸入氧浓度低于40%时,SpO2大于92%或动脉血气PaO2大于60 mmHg);(2)血流动力学稳定;(3)完整的气道反射和可控的气道分泌物。 术后常规镇痛方案:所有患儿术后均常规给予非阿片类药物镇痛。术后48小时内常规镇痛方案为静脉注射酮铬酸氨丁三醇 0.5 mg/kg Q6h和口服或经直肠给予对乙酰氨基酚 15 mg/kg Q6h(推荐使用为每3小时使用一种药物,即术后即刻使用酮咯酸氨丁三醇,三小时后使用对乙酰氨基酚,以此类推)。酮铬酸氨丁三醇常规间隔6小时两次后可以根据患儿疼痛程度逐渐增加给药间隔,也可逐渐停药或提前更换为口服布洛芬10 mg/kg Q6h PRN。术后48小时后,若仍有疼痛,停止使用静脉酮铬酸氨丁三醇,改为口服布洛芬10 mg/kg Q6h PRN;口服或经直肠使用对乙酰氨基酚改为12.5 mg/kg Q4h PRN。 术后补救镇痛方案:由ICU床旁护士对患儿进行FLACC疼痛评分(见附件1)。根据FLACC评分结果选择镇痛方式,FLACC评分0分:放松、舒适;1~3分:轻度疼痛;4~6分:中度疼痛;7~10分:重度疼痛。第一次、第二次FLACC评分≥4分,则静脉缓慢注射舒芬太尼0.05 μg/kg(两次舒芬太尼静脉注射间隔至少半小时);第三次FLACC评分≥4分则静脉缓慢注射舒芬太尼0.05 μg/kg后持续泵入舒芬太尼0.05 μg/kg/h。记录患儿术后24小时舒芬太尼等阿片类药物使用总量。记录患者术后6小时、12小时、18小时、24小时的FLACC评分。 

Description for medicine or protocol of treatment in detail:

Standard Anesthesia Management Upon arrival in the operating room, the patients will be sedated with inhalation sevoflurane (Sev) 6-8% and inserted a peripheral venous cannula. Intravenous anesthesia is induced with dexamethasone (0.3mg/kg), midazolam (0.02mg/kg), penehyclidine hydrochloride (0.02mg/kg), and cisatracurium (0.2 mg/kg). Mechanical ventilation will start after endotracheal intubation to achieve an end-tidal carbon dioxide tension (PetCO2) 35–45mmHg, with limited inhaled oxygen concentration (FiO2) 30-60% and tidal volume (VT) no more than 10mL/kg during operation. Anesthesia will be maintained with continuous infusion of propofol 1-4 mg/kg/h, dexmedetomidine 1μg/kg/h, cisatracurium 0.2 mg/kg/h and combined with inhalation Sev 1-3%. Standard monitoring includes 5-lead electrocardiogram (ECG), pulse oximeter, arterial blood pressure (ABP), central venous pressure (CVP), nasopharyngeal temperature, rectal temperature and urine output. Heparinization for CPB will be based on a bolus dose of heparin 400 U/kg and maintenance of an activated clotting time (ACT) >410s during CPB. In PVB group, heparinization is performed an hour after PVB. After systemic heparinization, the ascending aorta, superior and inferior lumen will be cannulated. After aortic cross-clamping, cardio protection will be perfused. Surgery will be performed under mild hypothermia (32-34℃), with hemoglobin (Hb) >70 g/L during CPB. After weaning from CPB, modified ultrafiltration is used to make Hb reach about 100 g/L, protamine will be titrated to reverse heparin. After endotracheal intubation, patient randomized into the PVB group will be placed in a lateral position and underwent right T4 PVB. It is recommended to use the sagittal in-plane method under ultrasound guidance: the lower edge of the T4 spinous process on the right side selected as the punction point, the ultrasonic probe will be put about 2.5cm away from the spine on the operation side. The direction of the probe is parallel to the spinal column and perpendicular to the skin. The position of the probe will be adjusted until the pleura and the superior costotransverse ligament can be distinguished, thus defined the paravertebral space. After determining the position, inject the needle under the guidance of ultrasound to make it pass through the skin, external intercostal muscle and intercostal intima successively until reaching the paravertebral space. After pumping back without blood and fluid, inject 0.3% ropivacaine with a total amount of no more than 3 mg / kg. Pleural depression can be seen after injection. Other methods can also be used, such as sagittal out-of-plane method, horizontal (intercostal) in-plane or out-of-plane method, etc. Patients randomized into the control group will not undergo PVB. In order to comply with the principle of blinding and avoiding unnecessary complications, skin puncture will be applied at a similar position of PVB group. In control group, each dose of sufentanil 0.5 μg/kg iv. will be given before incision and aorta cannulate. In PVB group, the patients will not receive any opioids during operation, the Sev concentration and propofol dosage will be titrated according to the depth of sedation and hemodynamic changes. At the end of surgery, in the control group, subcutaneous infiltration anesthesia will be performed with 0.3% ropivacaine (total 1 mg/kg) at the surgical incision and the site of the drainage placement. While the PVB group patients will not receive subcutaneous infiltration anesthesia. Definition of PVB Failure The fluctuation of ABP value is greater than 20% of baseline value after incision. Remedial method for PVB failure: increasing the dose of sufentanil (total ≤ 1μg/kg iv.), the Sev inhalation concentration and propofol dosage will be adjusted according to clinical needs, to ensure the fluctuation of ABP value is less than 20% of baseline value after incision. During CPB, anesthesia will be maintained with continuous infusion of propofol 0.2-5 mg/kg/h, dexmedetomidine 1μg/kg/h and with or without inhalational anesthetics. Remedial analgesia Plan Postoperative pain is graded according to the FLACC scale, 0: relaxed and comfortable; 1- 3: mild pain; 4-6: moderate pain; 7-10: severe pain. The ICU nurse will perform FLACC scale any time if theres any change and the analgesia plan will be selected according to the results of the FLACC scale: if the first and second time to confront FLACC ≥4: ketorolac tromethamine 0.5 mg/kg iv. will be given; if FLACC ≥4 happened for a third time: sufentanil 0.5 μg/kg/h iv. will be initiated. Standard Endotracheal Extubation Criteria (1)Spontaneous breathing with VT>5mL/kg, respiratory rate (RR)<40/min, PetCO2<50mmHg, peripheral capillary oxygen saturation (SpO2)>92% or arterial blood oxygen partial pressure>60 mmHg with FiO2<40%.

随机方法(请说明由何人用什么方法产生随机序列):

对于签署知情同意且筛选入组的患儿,记录其基线信息[年龄(1~6岁)、术式(是否拟行室间隔缺损修补术)、入选排除标准等],并在其进入手术室后进行随机分组。采用区组随机方法对患儿进行随机分组,计算机生成随机数后将所有随机数按照顺序编码密封至不透光的信封中,信封外面写上编码,即入选号,信封内放置随机号。将患儿随机分为试验组(PVB组)和对照组(传统组)。术中由非盲麻醉医师打开信封并根据分组结果对入选患儿给予相应治疗。

Randomization Procedure (please state who generates the random number sequence and by what method):

Patients will be randomized in two groups (control group and PVB group). In order to ensure group comparability, a block randomization will be used. Randomization will be done by investigators as close as possible to the surgery. Each patient will be given a unique patient number and a randomization num

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于采用两种完全不同的术中麻醉方案,无法做到术中麻醉管理者进行设盲。故术中麻醉管理医师不设盲,但术中麻醉管理医师将不进行术后访视。术中非盲CRA在留取血样和记录时也仅标记患者入选号及时间点、不标记患者分组。患者及家属盲(对照组后背相同位置用试验组相同的穿刺针刺入皮肤,这样表面上家属及其他临床医师就无法知道患儿分组)。评估者设盲(术后进行疼痛评分者不知道患儿分组、中心实验室在内的第三方独立评价时也不知道患儿分组)。

Blinding:

The anesthesiologists will be aware of patients group allocation because they will provide the intervention and be alert to the possible complications, but they will not be involved in either the postoperative treatment or the analysis. The patients, guardians, surgeons, ICU physicians, data collectors, and data analysts are not aware of the trial grouping in the whole process.
