目的:老年肺癌根治术应用广泛,文中探讨急性高容量血液稀释对老年肺癌根治术患者术后认知功能、血浆S100β的影响。方法选取华北理工大学附属医院2012年10月至2014年10月老年肺癌根治术患者112例,采用随机数字表法分为2组,稀释组(56例):患者实施急性高容量血液稀释。对照组(56例):患者未实施急性高容量血液稀释。采用简易精神状态量表( mini-mental state examination , MMSE)评定患者的认知功能,比较2组患者T0(麻醉诱导后即刻)、T1(血液稀释15 min)、T2(血液稀释60 min)、T3(手术结束前60 min)、T4(手术结束时)时间点脑氧代谢指标(血氧饱和度、血氧含量差、脑氧摄取率、乳酸差)、血浆S100β,以及术前、术后1、3、5、7 d的MMSE评分。结果 T1、T2、T3、T4时刻的稀释组患者血氧饱和度分别为(75.1±4.3)%、(78.5±3.1)%、(79.1±4.4)%、(79.6±2.8)%;血氧含量差、脑氧摄取率均随时间逐渐降低,与T0时刻比较差异均有统计学意义(P<0.05);对照组血氧饱和度分别为(63.4±2.0)%、(63.9±1.8)%、(64.2±3.0)%、(64.7±3.2)%,组间同时间点比较,差异均有统计学意义(P<0.05);T1、T 2、T3、T4时刻的稀释组患者血浆S100β分别为(0.53±0.04)、(0.52±0.07)、(0.51±0.06)、(0.50±0.08)μg/L,对照组分别为(0.64±0.06)、(0.64±0.04)、(0.65±0.05)、(0.67±0.06)μg/L,组间同时间点比较的差异有统计学意义(P<0.05)。术后1、3、5、7 d,稀释组MMSE评分分别为(24.3±1.7)、(26.5±1.9)、(27.8±1.3)、(28.1±1.0)分,对照组分别为(21.1±1.6)、(24.0±2.1)、(25.9±1.8)、(26.4±1.7)分,组间同时间点比较,稀释组MMSE评分均明显高于对照组(P<0.05)。结论急性高容量血液稀释可明显改善老年肺癌根治术患者术后认知功能状况,降低血浆S100β,可能与脑氧代谢有关。
目的:老年肺癌根治術應用廣汎,文中探討急性高容量血液稀釋對老年肺癌根治術患者術後認知功能、血漿S100β的影響。方法選取華北理工大學附屬醫院2012年10月至2014年10月老年肺癌根治術患者112例,採用隨機數字錶法分為2組,稀釋組(56例):患者實施急性高容量血液稀釋。對照組(56例):患者未實施急性高容量血液稀釋。採用簡易精神狀態量錶( mini-mental state examination , MMSE)評定患者的認知功能,比較2組患者T0(痳醉誘導後即刻)、T1(血液稀釋15 min)、T2(血液稀釋60 min)、T3(手術結束前60 min)、T4(手術結束時)時間點腦氧代謝指標(血氧飽和度、血氧含量差、腦氧攝取率、乳痠差)、血漿S100β,以及術前、術後1、3、5、7 d的MMSE評分。結果 T1、T2、T3、T4時刻的稀釋組患者血氧飽和度分彆為(75.1±4.3)%、(78.5±3.1)%、(79.1±4.4)%、(79.6±2.8)%;血氧含量差、腦氧攝取率均隨時間逐漸降低,與T0時刻比較差異均有統計學意義(P<0.05);對照組血氧飽和度分彆為(63.4±2.0)%、(63.9±1.8)%、(64.2±3.0)%、(64.7±3.2)%,組間同時間點比較,差異均有統計學意義(P<0.05);T1、T 2、T3、T4時刻的稀釋組患者血漿S100β分彆為(0.53±0.04)、(0.52±0.07)、(0.51±0.06)、(0.50±0.08)μg/L,對照組分彆為(0.64±0.06)、(0.64±0.04)、(0.65±0.05)、(0.67±0.06)μg/L,組間同時間點比較的差異有統計學意義(P<0.05)。術後1、3、5、7 d,稀釋組MMSE評分分彆為(24.3±1.7)、(26.5±1.9)、(27.8±1.3)、(28.1±1.0)分,對照組分彆為(21.1±1.6)、(24.0±2.1)、(25.9±1.8)、(26.4±1.7)分,組間同時間點比較,稀釋組MMSE評分均明顯高于對照組(P<0.05)。結論急性高容量血液稀釋可明顯改善老年肺癌根治術患者術後認知功能狀況,降低血漿S100β,可能與腦氧代謝有關。

Objective Radical surgery is extensively used in the treatment of lung cancer in elderly patients .This study aimed to investigate the effects of acute hypervolemic hemodilution (AHVHD) on the cognitive function and plasma S100βof elderly people following radical surgery for lung cancer . Methods A total of 112 lung cancer patients treated by radical surgery were equally randomized to an AHVHD and a non-AHVHD control group .Using the Mini-Mental State Examination scale ( MMSE) , we evaluated the cognitive function of the patients .We made comparisons between the two groups in the cerebral oxygen metabolism indexes and plasma S100βlevels at T0(immediately after anesthesia induction), T1(15 min after hemodilution), T2(60 min after hemodilution), T3(60 min before the end of surgery ) and T4 ( at the end of surgery ) as well as MMSE scores before and after operation . Results At T1 , T2, T3, and T4, the values of jugular venous oxygen saturation in the AHVHD group were (75.1 ±4.3), (78.5 ±3.1), (79.1 ± 4.4), and (79.6 ±2.8) %, respectively, with time-dependent decreases in Da-jvO2 and cerebral oxygen extraction , and significantly higher than that at T0 (P<0.05) and those in the control group ([63.4 ±2.0], [63.9 ±1.8], [64.2 ±3.0], and [64.7 ±3.2]%) (P<0.05).The levels of plasma S100βat T1, T2, T3, and T4 were remarkably lower in the AHVHD group ([0.53 ±0.04], [0.52 ±0.07], [0.51 ±0.06], and [0.50 ±0.08] μg/L) than in the control ([0.64 ±0.06], [0.64 ±0.04], [0.65 ±0.05], and [0.67 ±0.06] μg/L), with statistically significant differences between the two groups at the same time point (P<0.05).At 1, 3, 5, and 7 days after surgery, the MMSE scores were markedly higher in the AHVHD group (24.3 ±1.7, 26.5 ±1.9, 27.8 ±1.3, and 28.1 ±1.0) than in the control (21.1 ±1.6, 24.0 ±2.1, 25.9 ±1.8, and 26.4 ±1.7) (P<0.05). Conclusion AHVHD can significantly improve cognitive function and reduce plasma S 100βin elderly patients following radical surgery for lung cancer , which may be related to cerebral oxygen metabolism .
