| 目的 通过对实验犬硬膜外腔穿刺的研究来判断硬膜外腔雾气现象能否准确定位硬膜外导管的位置。方法 选取实验犬8条在B超引导下将硬膜外导管依次置入皮下脂肪、肌肉层、韧带层和硬膜外腔后用无菌注射器回抽,置入无水硫酸铜粉末涂抹内壁的硬膜外导管,无水硫酸铜具有遇水变蓝的特性,观察硬膜外导管内壁变色来判断出现雾气现象,认定其已进入硬膜外腔并注入局麻药。根据是否出现硬膜外阻滞效果从而最终确认硬膜外导管是否位于硬膜外腔。结果 硬膜外导管进入硬膜外腔后全部观察到变色现象,硬膜外导管在皮下脂肪、肌肉层和韧带层均未观察到变色现象。结论 证实硬膜外腔雾气现象具有独特性,可作为判断硬膜外腔穿刺置管成功与否的重要标准。 |

| Objective To study whether the location of the epidural catheter in dogs can be determined by the fog phenomenon.Methods Epidural catheters were placed ordinally into the subcutaneous fat,muscle,ligament and epidural cavity with ultrasound-guidance in 8 experimental dogs.Then the sterile syringe was used for pumpback and anhydrous copper sulfate powder was put in and smeared the inner wall of epidural catheter.Anhydrous copper sulfate had the characteristics of turning blue in water,therefore,the inner wall discoloration of epidural catheter could be used to judge the occurrence of fog phenomenon and ascertain that the epidural catheter had been put into the epidural cavity and local anesthetics had been injected.The epidural catheter was ultimately confirmed to be in the epidural cavity depending on whether there occurred epidural blockage.Results Fog phenomenon was observed when epidural catheter entered the epidural cavity,and no fog phenomenon was observed when epidural catheter was in subcutaneous fat,muscle,and ligament.Conclusions It has been proved that fog phenomenon of epidural catheter was specific,which could be used as an important criterion for judging the position of epidural catheter. |
