腹腔镜手术中纱布含血量的实验研究

Study on Gauze Blood Content in Laparoscopic Surgery

目的对腹腔镜手术中常用的无纺纱布含液量进行测试,评估患者术中失血量。方法使用生理盐水进行无纺纱布含液量实验,对10 cm×10 cm 4层无纺纱布、7 cm×7 cm 4层无纺纱布、8 cm×10 cm 8层无纺纱布用0. 9%Na Cl进行模拟腹腔镜手术含液量试验。结果 10 cm×10 cm 4层无纺纱布饱和度是10 ml,经10 mm腹腔镜trocar取出后含液量是9 ml;7 cm×7 cm 4层无纺纱布饱和度是8 ml,经10 mm腹腔镜trocar取出后含液量是6 ml;8 cm×10 cm 8层无纺纱布饱和度是12 ml,经10 mm腹腔镜trocar取出后含液量是10 ml。结论对腹腔镜手术中常用的无纺纱布含液量进行测试,可帮助术者及麻醉医师有效估算术中失血量。

Objective To measure the liquid content of non-woven yarn used in laparoscopic surgery to evaluate the blood volume and fluid loss during operation. Methods The liquid content of non-woven yarn was tested with saline. The liquid content of simulated laparoscopic operation was tested with 10 cm×10 cm 4-layer non-woven yarn, 7 cm×7 cm 4-layer non-woven yarn and 8 cm×10 cm 8-layer non-woven yarn by using 0.9% sodium chloride. Results The saturation of 10 cm×10 cm 4-layer non-woven fabric was 10 ml, and the liquid content was 9 ml after removal of 10-mm laparoscopic trocar;the saturation of 7 cm×7 cm 4-layer of non-woven fabric was 8 ml, and the liquid content was 6 ml after removal of 10-mm laparoscopic trocar;the saturation of 8 cm×10 cm 8-layer of non-woven fabric was 12 ml, and the liquid content after removal of 10-mm laparoscopic trocar was 10 ml. Conclusion Testing the liquid content of non-woven yarn commonly used in laparoscopic surgery can help operators and anesthesiologists estimate intraoperative bleeding effectively.
