摘要 目的探讨右美托咪定对单肺通气(OLV)患者肺内分流以及炎性反应的影响。方法选择56例择期行食管癌根治术患者,按随机数字表法分为右美托咪定组和对照组,每组28例。分别于开胸前(T0)、OLV后45min(T1)、OLV后90min(T2)、术后6h(T3)以及术后24h(T4)检测血清白细胞介素(IL)-6、IL-8和肿瘤坏死因子仪(TNF-α)浓度并计算肺内分流率(Qs/Qt)。结果与T0时比较,T0~T4时两组患者血清TNF-α、IL-6、IL-8浓度显著升高[右美托眯定组:(30.4±4.7)、(51.6±7.8)、(81.6±7.6)、(127.2±16.8)ng/L比(19.7±3.8)ng/L;(17.9±4.4)、(37.1±9.6)、(89,6±12.9)、(78.9±13.1)ng/L比(15.0±2.9)ng/L;(14.9±2.2)、(19.8±3.3)、(36.2±4.0)、(35.8±6.5)ng/L比(7.6±1.4)ng/L;对照组:(33.6±3.9)、(79.8±6.3)、(101.5±10.2)、(145.3±17.3)ng/L比(18.2±3.4)ng/L;(21.6±5.3)、(46.9±10.2)、(112.5±13.6)、(106.2±15.6)ng/L比(15.3±2.8)ng/L;(16.1±2.8)、(26.3±4.7)、(47.6±5.1)、(40.2±6.2)ng/L比(8.3±2.0)ng/L],差异有统计学意义(P〈0.01)。T2-T4时两组患者血清TNF-α、IL-6、IL-8浓度比较差异亦有统计学意义(p〈0.05)。但是,两组间Qs/Qt比较差异无统计学意义(P〉0.05)。结论围手术期持续输注右美托咪定在一定程度上能减轻OLV时炎性反应,但对肺内分流无明显影响。 Objective To explore the effects of dexmedetomidine on intrapulmonary shunt and inflammatory response in patients with one lung ventilation (OLV). Methods Fifty-six patients scheduled for radical resection of esophageal cancer were divided by random digits table method into dexmedetomidine group and control group with 28 cases each. Serum levels of interleukin (IL)-6, IL-8,tumor necrosis factor alpha(TNF- α ) before opening the chest(T0) ,at 30 min(T1) and 90 min (T2) after OLV,at 6 h(T3) and 24 h (T4) after operation were detected and the intrapulmonary shunt fraction (Qs/Qt) was calculated. Results Compared with To, serum levels of TNF- α, IL-6 and IL-8 increased in both groups at T1-T4 [ dexmedetomidine group: (30.4 ± 4.7), (51.6 ± 7.8), (81.6 ± 7.6), ( 127.2 ± 16.8) ng/L vs. ( 19.7 ± 3.8) ng/L; ( 17.9 ± 4.4), (37.1 ± 9.6), (89.6 ± 12.9), (78.9 ± 13.1 ) ng/L vs.( 15.0 ± 2.9) ng]L; ( 14.9 ± 2.2), ( 19.8 ± 3.3), (36.2 ± 4.0), (35.8 ± 6.5) ng/L vs. (7.6 ± 1.4) ng/L;control group: (33.6 ± 3.9), (79.8 ± 6.3), ( 101.5 ± 10.2),(145.3 ± 17.3) ng/L vs.(18.2 ±3.4) ng/L; (21.6 ± 5.3), (46.9 ± 10.2), (112.5 ± 13.6), (106.2 ± 15.6) ng,/L vs. (15.3 ±2.8) ng/L; (16.1 ±2.8), (26.3 ±4.7), (47.6 ±5.1), (40.2 ±6.2) ng/L vs. (8.3 ±2.0) ng/L] ,which had significant differences (P 〈 0.01). There were statistical significance in the levels of TNF- α, IL-6 and IL-8 at T2-T4 between two groups (P 〈 0.05 ). However, there was no statistical difference in Qs/Qt between two groups(P 〉 0.05). Conclusions Perioperative continuous infusion of dexmedetomidine can reduce the inflammatory responses to a certain extent during OLV. But it has no obvious effects on intrapulmonary shunt.
