Abstract:

Objective To investigate the effects of dexmedetomidine intervention on procalcitonin(PCT), tumor necrosis factor - α(TNF - α), helper T cell (Th17) levels, and cognitive function in patientswith decompensated cirrhosis undergoing liver transplantation surgery. Methods A total number of 72 patientswho underwent liver transplantation surgery due to decompensated cirrhosis and were treated in Shenzhen Third People's Hospital from November 2022 to November 2023 were randomly divided into a study group (D group,n = 36) and a control group (NS group,n = 36). The D group received intravenous infusion of dexmedetomidine loading dose after entering theroom and maintained it until the end of the surgery, while the NS group received an equal dose of physiological saline. Basic vital signs, including mean blood pressure (MAP), heart rate (HR),pulse oxygen saturation(SPO2 ),cardiac output(CO),and central venous pressure (CVP),5 mins before anesthesia (T1 ),5 mins after tracheal intubation (T2 ),5 mins before surgery (T3 ),5 mins before anhepatic phase (T4 ),5 mins before anhepatic phase (T5 ),5 mins before new liver phase (T6 ), 5 mins after new liver phase (T7 ), and at the end of surgery (T8 ). Changes in PCT, TNF - α, and Th17 levels between two groups of patients at 24 h before surgery,24 h after surgery, and 72 h after surgery, as well as the incidence of secondary infections at 15 d after surgery were compared. At the same time, the cognitive function of the two groups of patients was evaluated using the Montreal Cognitive Assessment Scale (MMSE)24 h before and 72 h after surgery, and the total amount of vasoactive drugs during surgery,intensive care unit (ICU) stay time after surgery, and total length of hospital stay after surgery were compared between the two groups of patients. Results Compared with the NS group, there was no significant difference in basic vital signs at all time points in the D group. The PCT and Th17 levels were lower in the D group at 24 and 72 h after surgery (P < 0.05). The level of TNF - α was lower at 24 h postoperatively (P < 0.05), but there was no difference at 72 h. On postoperative day 15, there was no significant difference in the incidence of secondary infections between group D (5/36,13.89%) and group NS (7/36,19.44%)(P > 0.05). In terms of cognitive function assessment, there was no significant difference in MMSE scores between the two groups before surgery (P > 0.05),and the MMSE score in group D was higher than that in group NS at 72 h after surgery (P < 0.05). Concusion The use of dexmedetomidine during general anesthesia can effectively reduce the levels of PCT, TNF - α, and Th17 after liver transplantation in patients with decompensated cirrhosis, and alleviate inflammatory reactions. Meanwhile,dexmedetomidine can also improve postoperative cognitive function. These results suggest that dexmedetomidine has potential clinical value in the prognosis of liver transplantation in the decompensated phase of hepatitis cirrhosis.

摘要:

目的 探讨肝硬化失代偿患者行肝移植手术应用右美托咪定干预对降钙素原(procalcitoninPCT)、肿瘤坏死因子 -α(tumor necrosis factor-α,TNF-α)、辅助性 T 细胞 17(T helper cell 17,Th17)水平以及认知功能的影响。方法 选取 2022 年 11 月至 2023 年 11 月期间在深圳市第三人民医院,因肝硬化失代偿行肝移植手术的 72 例患者,分为研究组(D 组,n = 36)和对照组(NS 组,n = 36)。D 组在入室后静脉泵注右美托咪定负荷剂量后维持至术毕,NS 组接受等剂量生理盐水。记录麻醉开始前 5 mins (T1)、气管插管后 5 mins (T2)、手术开始 5 mins (T3)、无肝期前 5 mins(T4)、无肝期开始 5 mins(T5)、新肝期前5 mins(T6)、新肝期后 5 mins(T7)及手术结束(T8)的基本生命体征,主要包括 :平均动脉压(mean arterial pressure,MAP)、心率(heart rate,HR)、指尖脉搏氧饱和度(pulse oxygen saturation,SPO2)、每博输出量(cardiac output,CO)和中心静脉压(central venous pressure,CVP)等。比较两组患者在术前 24 h、术后 24 h 和术后 72 h 时 PCT、TNF-α 和 Th17 水平的变化及术后 15 d 继发感染情况。同时,使用蒙特利尔认知评估量表(Montreal Cognitive Assessment Scale,MMSE)对两组患者术前 24 h、术后 72 h 的认知功能进行评估,比较两组患者术中血管活性药物总量、术后重症监护病房(intensive care unit,ICU)停留时长、术后总住院天数等。结果 与 NS 组相比,D 组各时间点基本生命体征无明显差异,D 组术后 24 h 和 72 h 时 PCT 和 Th17 水平更低(P < 0.05)。术后 24 h 时 TNF-α 水平更低(P < 0.05),但在 72 h 时无差异。术后 15 d D 组继发感染情况(5/36,13.89%)与 NS 组(7/36,19.44%)不具有统计学差异(P > 0.05)。在认知功能评估方面,术前两组 MMSE评分不具有统计学差异(P > 0.05),D 组术后 72 h 时 MMSE 评分高于 NS 组(P < 0.05)。结论全身麻醉中使用右美托咪定能有效降低肝硬化失代偿期患者肝移植术后 PCT、TNF-α 和 Th17 水平,减轻炎症反应。同时,右美托咪定还能改善术后的认知功能。这些结果表明右美托咪定在肝硬化失代偿期行肝移植术的预后具有潜在的临床应用价值。
