药物成份或治疗方案详述: |
我们计划实行60例患者,所有患者均是全麻下择期行非心脏大型手术(四级手术),随机将患者分配至进行目标导向治疗组(FloTrac组)或HPI软件监测组(HPI组)。患者入室后监测心率(HR)、心电图(ECG)、脑电双频指数(BIS)和脉氧饱和度(SpO2)。开放静脉通路,输注复方氯化钠注射液维持循环功能。局麻下行桡动脉穿刺置管监测有创动脉压(ABP) ,并开始Flotrac或HPI监测。记录麻醉诱导前平均动脉压(MAP),静脉注射咪达唑仑(0.03~0.05 mg/kg)静脉注射丙泊酚(1.5~2.5 mg/kg),舒芬太尼(0.3~0.5 µg/kg),待病人意识消失后,静脉注射罗库溴铵1mg/kg,然后进行气管搬插管,术中使用丙泊酚和瑞芬太尼持续静注,七氟醚持续吸入进行维持。Flotrac传感器或Acumen IQ传感器分别用于分配到Flotrac组和HPI组的患者。传感器连接到HemoSphere(Edwards Lifesciences,Irvine,CA,USA)以监测血流动力学参数,包括平均动脉压(MAP)、SVV、SVR、SV和HPI(仅在HPI组中)。HPI的范围为0到100,当HPI超过85时,会出现声音和视觉警报。当MAP<65 mmHg(Flotrac组)、MAP<65 mm Hg或HPI>85(HPI组)发生时,麻醉医师需要根据决策流程图判断血流动力学参数并进行干预,以实现MAP≥65 mmHg或MAP≥65 mm Hg和HPI≤85。液体类型和总量由麻醉医师考虑多种因素确定,血管活性药物使用静脉泵注去甲肾上腺素或使用麻黄碱。 所有血流动力学数据每20秒记录一次在HemoSphere监测仪上,并在手术完成后导出。使用Acumen分析软件(Edwards Lifesciences,Irvine,CA,USA)对输出的血流动力学数据进行分析。低血压事件定义为持续至少1分钟的MAP<65 mmHg。阈值下面积(AUT)和AUT时间加权平均值(TWA-AUT)如前所述计算。AUT的计算方法是MAP为65 mmHg时的面积除以总监测持续时间,得出TWA-AUT(mmHg)。还计算并分析了每位患者的低血压事件数量、每位患者的总低血压持续时间、每位患者在低血压期间的平均MAP以及MAP<50 mmHg的低血压事件的数量。此外,还需要记录患者的一般生命体征和术中补液参数,包括施用的晶体、胶体和血液制品的量;失血量和尿量;使用麻黄碱的剂量;去甲肾上腺素的频率和剂量;以及监测期间血红蛋白的最大和最小值。此外,还记录两组患者术后7天及术后30天脑梗塞、脑出血、急性肾衰、急性肺部感染、心肌梗塞等术后并发症发生率及死亡率。 |

Description for medicine or protocol of treatment in detail: |
We plan to enroll 60 patients, all of whom will undergo elective non-cardiac major surgery (level 4 surgery) under general anesthesia. The patients will be randomly assigned to either the goal-directed treatment group (FloTrac group) or the HPI software monitoring group (HPI group). After the patient enters the operating room, heart rate (HR), electrocardiogram (ECG), bispectral index (BIS), and pulse oximetry saturation (SpO2) will be monitored. Venous access will be established, and compound sodium chloride injection will be administered to maintain circulatory function. Under local anesthesia, radial artery puncture and catheterization will be performed to monitor invasive arterial blood pressure (ABP), and FloTrac or HPI monitoring will be initiated. The mean arterial pressure (MAP) before anesthesia induction will be recorded. Patients will receive intravenous midazolam (0.03–0.05 mg/kg), intravenous propofol (1.5–2.5 mg/kg), and sufentanil (0.3–0.5 µg/kg). After the patient’s consciousness is lost, intravenous rocuronium bromide (1 mg/kg) will be administered, followed by tracheal intubation. During the operation, propofol and remifentanil will be continuously infused intravenously, and sevoflurane will be inhaled continuously for maintenance. FloTrac sensors or Acumen IQ sensors will be used for patients assigned to the FloTrac group and HPI group, respectively. The sensors will be connected to the HemoSphere monitor (Edwards Lifesciences, Irvine, CA, USA) to monitor hemodynamic parameters, including mean arterial pressure (MAP), stroke volume variation (SVV), systemic vascular resistance (SVR), stroke volume (SV), and hypotension prediction index (HPI, only in the HPI group). The range of HPI is from 0 to 100, and audible and visual alarms will be triggered when HPI exceeds 85. When MAP < 65 mmHg occurs in the FloTrac group, or MAP < 65 mmHg or HPI > 85 occurs in the HPI group, the anesthesiologist will determine the hemodynamic parameters based on a decision algorithm and intervene to achieve MAP ≥ 65 mmHg or MAP ≥ 65 mmHg and HPI ≤ 85. The type and total volume of fluids will be determined by the anesthesiologist considering various factors, and vasoactive drugs will be administered through intravenous infusion of norepinephrine or ephedrine. All hemodynamic data will be recorded every 20 seconds on the HemoSphere monitor and exported after the surgery is completed. The exported hemodynamic data will be analyzed using Acumen analysis software (Edwards Lifesciences, Irvine, CA, USA). Hypotension events are defined as MAP < 65 mmHg lasting for at least 1 minute. The area under the threshold (AUT) and time-weighted average of AUT (TWA-AUT) will be calculated as previously described. The calculation method for AUT is to divide the area below a MAP of 65 mmHg by the total duration of monitoring to obtain TWA-AUT (mmHg). We will also calculate and analyze the number of hypotensive events per patient, the total duration of hypotension per patient, the average MAP during hypotension for each patient, and the number of hypotensive events with MAP < 50 mmHg.In addition, we will record the patients' general vital signs and intraoperative fluid administration parameters, including the amounts of crystalloids, colloids, and blood products administered; blood loss and urine output; the dose of ephedrine used; the frequency and dose of norepinephrine; and the maximum and minimum values of hemoglobin during the monitoring period. Furthermore, we will record the incidence of postoperative complications such as cerebral infarction, cerebral hemorrhage, acute renal failure, acute pulmonary infection, and myocardial infarction, as well as mortality rates, at 7 days and 30 days after surgery for both groups of patients. |
