目的 通过体外基础研究探讨不同大小的引流管对不同性质液体的引流效果,确定能满足临床上胸腔引流需要的引流管大小.方法 体外实验把1000 mL 30％血球压积的全血、2.5％白蛋白溶液、0.9％生理盐水分成A、B、C三组,分别用管径为6F(French,F)、8F、10F、12F、14F、16F、18F、20F、22F、24F、26F、28F、30F、32F、34F、36F引流管进行重复引流,计算引流量.相同性质液体采用不同大小引流管的引流量之间的比较采用单因素方差分析,不同性质液体采用不同大小引流管的引流量之间的多重比较采用双因素方差分析,并遵照泊肃叶公式进行曲线拟合.结果 三组液体的引流量与引流管大小成正相关,双因素方差分析中6F与8F引流管差异无统计学意义(P=0.513),其他大小引流管多重比较,差异有统计学意义(P＜0.05);A组引流量数据单因素方差分析中,与引流量为3.33 mL/min的对照值比较,6F和8F引流管引流量大于3.33 mL/min,但差异无统计学意义(P＞0.05),10F及以上的引流管的引流量明显大于对照值(P＜0.05).拟合曲线方程分别为:A组Q=0.002 9x4,R2 =0.991;B组Q=0.003 2x4,R2=0.981;C组引流量Q=0.003 4x4,R2=0.975.当Q=3.33时,A组引流量拟合曲线方程中X≈5.82F.结论 本基础实验研究提示小管径引流管(6F ～ 14F)理论上可以满足临床上对血胸、渗出液及漏出液的引流.
目的 通過體外基礎研究探討不同大小的引流管對不同性質液體的引流效果,確定能滿足臨床上胸腔引流需要的引流管大小.方法 體外實驗把1000 mL 30％血毬壓積的全血、2.5％白蛋白溶液、0.9％生理鹽水分成A、B、C三組,分彆用管徑為6F(French,F)、8F、10F、12F、14F、16F、18F、20F、22F、24F、26F、28F、30F、32F、34F、36F引流管進行重複引流,計算引流量.相同性質液體採用不同大小引流管的引流量之間的比較採用單因素方差分析,不同性質液體採用不同大小引流管的引流量之間的多重比較採用雙因素方差分析,併遵照泊肅葉公式進行麯線擬閤.結果 三組液體的引流量與引流管大小成正相關,雙因素方差分析中6F與8F引流管差異無統計學意義(P=0.513),其他大小引流管多重比較,差異有統計學意義(P＜0.05);A組引流量數據單因素方差分析中,與引流量為3.33 mL/min的對照值比較,6F和8F引流管引流量大于3.33 mL/min,但差異無統計學意義(P＞0.05),10F及以上的引流管的引流量明顯大于對照值(P＜0.05).擬閤麯線方程分彆為:A組Q=0.002 9x4,R2 =0.991;B組Q=0.003 2x4,R2=0.981;C組引流量Q=0.003 4x4,R2=0.975.噹Q=3.33時,A組引流量擬閤麯線方程中X≈5.82F.結論 本基礎實驗研究提示小管徑引流管(6F ～ 14F)理論上可以滿足臨床上對血胸、滲齣液及漏齣液的引流.

Objective To determine the appropriate size of the tube for the thoracic drainage in good efficiency by the experimental study in the influence of the tube size on the flow rate of the fluid with different properties.Methods Three groups were divided according to the different components in the fluid:group A,whole blood with 30％ hematocrit; group B,2.5％ albumin solution; and group C,0.9％ normal saline.The total volume of the fluid was 1000 mL in each group in the experiment.Different sorts of fluids were drained with the chest tubes with different diameters (6F,8F,10F,12F,14F,16F,18F,20F,22F,24F,26F,28F,30F,32F,34F,36F of French F) separately,and the flow rate was calculated.ANOVA was used for the comparison of the differences in flow rate among the groups with given fluid property.Twofactor analysis of variance was used for the analysis of flow rates of fluid with different fluid properties.Curve fitting was performed according to the Poiseuille formula.Results The flow rate was positively correlated with the size of the chest drainage tube.The difference in flow rate among the tubes with difference in size was statistically significant (P ＜ 0.05) but there was no noticeable difference in flow rate between 6F and 8F (P =0.513).The flow rate of the 6F and 8F tubes was higher than that of the control (3.33 mL/min) but there was no significant difference between them (P ＞ 0.05).The flow rate of the tubes in 10F and above was obviously higher than that of control (P ＜ 0.05).The curve was estimated that group A was Q =0.002 9x4,R2 =0.991; group B Q=0.003 2x4,R2 =0.981; group C Q =0.003 4x4,R2 =0.975.When the flow rate was fixed at 3.33 mL/min,the estimated curve in group A was X ≈ 5.82F.Conclusions Our experiment indicated that the chest tube with small diameters (6F-14F) could meet the demand of high efficient drainage in the patients with hemothorax or pleural effusion.
