摘要】 目的 研究单肺通气(one-lung ventilation, OLV)期间舒芬太尼和芬太尼对血液氧合及肺内分流的影响。 方法 择期食道癌根治术患者26例,美国麻醉医师协会(ASA)分级Ⅰ~Ⅱ级,采用随机数字表法分为A、B两组(每组13例),A组麻醉诱导:咪达唑仑0.1 mg/kg、丙泊酚1 mg/kg~2 mg/kg、舒芬太尼0.3 μg/kg、维库溴铵0.1 mg/kg;B组:咪达唑仑、丙泊酚、维库溴铵用量与A组相同,芬太尼3 μg/kg。麻醉维持:两组均静脉持续泵入丙泊酚3 mg·kg-1·h-1~6 mg·kg-1·h-1、间断追加维库溴铵0.05 mg/kg,分别在麻醉诱导后切皮前双肺通气(total lung ventilation, TLV)和OLV结束时静注舒芬太尼0.1 μg/kg~0.2 μg/kg或芬太尼1 μg/kg~2 μg/kg维持麻醉。观察两组双肺通气切皮前(total?蛳lung ventilation, TLV-T0)、 OLV 30 min和60 min时动静脉血气分析变化,并计算肺内分流率(pulmonary shunt fraction, Qs/Qt)。 结果 OLV 30、60 min动脉血氧分压(arterial partial pressure of oxygen, PaO2)[A组:OLV 30 min-PaO2(138±29) mmHg(1 mmHg=0.133 kPa),OLV 60 min PaO2 (135±26) mmHg,TLV-T0-PaO2(225±30) mmHg;B组:OLV 30 min-PaO2(121±31) mmHg,OLV 60 min PaO2 (120±29) mmHg,TLV-T0-PaO2 (217±29) mmHg];与TLV-T0比较,OLV 30、60 min PaO2明显下降(P<0.05);而舒芬太尼组与芬太尼组比较,对OLV期间PaO2、Qs/Qt、PvO2、血氧饱和度(blood oxygen saturation, SaO2)、动脉血氧含量(arterial oxygen content, CaO2)的影响,差异均无统计学意义。 结论 舒芬太尼较芬太尼对OLV期间血液氧合和肺内分流无明显改善作用。

【Abstract】 Objective To evaluate the effects of sufentanil and fentanyl on oxygenation and pulmonary shunt fraction during one-lung ventilation (OLV). Methods Twenty six patients(ASA Ⅰ-Ⅱ) undergoing thoracic surgery for esophagectomy were randomly divided into 2 groups (n=13): sufentanil group(group A) and fentanyl group(group B). Anesthesia was induced with midazolam 0.1 mg/kg, propofol 1 mg/kg-2 mg/kg, sufentanil 0.3 μg/kg (group A) or fentanyl 3 μg/kg (group B) and vecuronium 0.1 mg/kg. Anesthesia was maintained with propofol 3 mg·kg-1·h-1-6 mg·kg-1·h-1 to the end, vecuronium 0.05 mg/kg when necessary and sufentanil 0.1 μg/kg-0.2 μg/kg or fentanyl 1 μg/kg-2 μg/kg before cut off the skin and after the end of OLV. Blood samples were obtained from radial artery and right internal jugular vein respectively for determining arterial partial pressure of oxygen(PaO2) and pulmonary shunt fraction (Qs/Qt) at total-lung ventilation (TLV-T0) and 30(OLV 30 min), 60 min (OLV 60 min) after OLV. Results PaO2 was significantly decreased at OLV 30 min and OLV 60 min compared with TLV-T0[Group A: OLV 30 min-PaO2 (138±29) mmHg(1 mmHg=0.133 kPa), OLV 60 min PaO2 (135±26) mmHg, TLV-T0-PaO2 (225±30) mmHg. Group B: OLV 30 min-PaO2 (121±31) mmHg, OLV 60 min PaO2(120±29) mmHg, TLV-T0-PaO2(217±29) mmHg](P<0.05). But PaO2, Qs/Qt, PvO2, blood oxygen saturation(SaO2) and arterial oxygen content(CaO2) have no significantly differences between two groups during one-lung ventilation. Conclusions Compared with fentanyl, sufentanil have no significantly improving function on oxygenation and pulmonary shunt fraction during OLV.
