摘要:

目的 观察驱动压(DP)指导通气策略对婴儿胸腔镜手术单肺通气(OLV)时脑氧饱和度(SrcO2)的影响。 方法 60例择期胸腔镜手术婴儿随机分成对照组(C组)和驱动压力组(DP组),每组30例。通过近红外光谱仪监测SrcO2,以SrcO2较基线下降> 20%为低脑氧合(COD)。记录OLV期间低血压发生率、通气补救次数、COD发生率及其持续时间。比较两组婴儿胸人工气胸前(T1)、人工气胸后30 min(T2)和人工气胸后60 min(T3)的MAP、HR、SrcO2、PEEP、气道峰压(Ppeak),肺静态顺应性(Cs),以及人工气胸前后的动脉血气分析结果。 结果 两组在SrcO2基线、OLV时SrcO2平均值、低血压发生率、COD发生率上均差异无统计学意义(P > 0.05)。DP组通气补救次数和COD持续时间均低于C组(P < 0.05)。两组患儿在T1时的MAP、HR、SrcO2、Ppeak 、Cs、PaO2和OI均差异无统计学意义(P > 0.05)。与T1相比,两组患儿在T2和T3时Ppeak均升高,SrcO2和Cs降低(P < 0.05)。与C组相比,DP组在T2时PaO2和OI更高,T2和T3时Ppeak更低,PEEP和Cs更高(P < 0.05)。DP组患儿气管拔管时间和PACU停留时间短于C组(P < 0.05)。两组患儿苏醒延迟、二次气管插管和术后躁动的发生率差异均无统计学意义(P > 0.05)。 结论 DP通气策略可改善通气侧肺部顺应性,提高婴儿OLV时的氧合水平,缩短COD暴露时间。

Abstract:

Objective To investigate the effect of driving pressure (DP) guided ventilation strategy on regional cerebral oxygen saturation (SrcO2) in infants with one lung ventilation (OLV) during thoracoscopic surgery. Methods Sixty infants undergoing elective thoracoscopic surgery were randomly divided into control group (group C,n = 30)and driving pressure group (group DP, n = 30). Near?infrared spectroscopy was used to monitor SrcO2 during OLV. Cerebral oxygen desaturation (COD)was defined as SrcO2 decreased by more than 20% from baseline. The incidence of hypotension, time of ventilation rescue, the incidence of COD and its duration during OLV were recorded. MAP, HR, SrcO2, PEEP, airway peak pressure (Ppeak), static lung compliance (Cs) were recorded before (T1), 30 min after (T2) and 60 min after (T3)artificial pneumothorax, and results of arterial blood gas analysis on T1 and were T2 compared. Results There were no significant differences in the SrcO2 baseline, the mean SrcO2 during OLV, the incidence of hypotension and the incidence of COD between the two groups (P > 0.05). Times of ventilation rescue and COD duration in DP group were lower than those in C group(P < 0.05). There were no significant differences in MAP, HR, SrcO2, Ppeak, Cs, PaO2 and OI between the two groups at T1P > 0.05). Compared with T1, Ppeak increased and SrcO2 and Cs decreased in both groups at T2 and T3P < 0.05). Compared with group C, group DP had higher PaO2 and OI at T2, lower Ppeak and higher PEEP and Cs at T2 and T3P < 0.05). Conclusion DP guided ventilation strategy improved lung compliance, increased oxygen saturation and shortened the exposure of COD in infants during OLV.
