不同亮度环境下犬荧光留置针静脉穿刺的应用效果研究

目的通过动物实验验证在暗环境下应用荧光静脉留置针进行静脉穿刺的应用效果。方法模拟不同光亮度环境,应用荧光静脉留置针和普通静脉留置针分别对犬静脉进行静脉穿刺,对比穿刺成功率和穿刺时间。结果在晨昏光亮度组和低光亮度组应用2种静脉留置针进行穿刺的成功率和穿刺时间差异均有显著性(P0.05)。结论在晨昏光亮度和低光亮度的环境下使用荧光静脉留置针进行静脉穿刺具有提高穿刺成功率、缩短穿刺时间的优点。

Application value of fluorescent intravenous indwelling catheter in dogs under different brightness conditions

Objective To evaluate the clinical effectiveness of venipuncture using the fluorescent intravenous indwelling catheter in dark environment in dog experiments. Methods Six dogs were randomly divided into three groups of two dogs each, and each dog was subjected to 40 times of venipuncture performed on a foreleg with normal intravenous indwelling catheter and fluorescent intravenous indwelling catheter, respectively, under high (101-105 lux), moderate (10.2-100 lux) or low (5-10 lux) brightness conditions. The success rates and time consumption of those two procedures were analyzed and compared statistically. Results The success rate and time consumption for venipuncture using fluorescent and normal intravenous indwelling catheter under low brightness were 82.5% and (204.36±13.13) s vs. 40.0% and (249.35±17.98) s, those performed under moderate (simulating morning and dawn) brightness were 90.0% and (194.86±8.60) s vs. 67.5% and (206.37±9.70) s, all showed a significantly higher efficiency of the venipuncture using fluorescent intravenous indwelling catheter (P < 0.05). Conclusions The use of fluorescent intravenous indwelling catheter has the advantages of higher success rate and shorter time consumption for venipuncture under low and moderate brightness conditions.
