本文介绍应用超声定点定位法对77例胸水患者共172次指导穿刺抽水,全都成功;而后95次抽水,失败5次,其原因是胸水腔间隙小,但向腔内注入治疗药物顺利。本组172例次均未出现气胸不良损伤。 方法:采用12号注射针,将针尖磨圆,外套塑料管。胸穿前,首先对患侧胸部进行常规检查,然后选择适于穿刺的肋间,将指导针放在探头与皮肤之间(图1)。由于金属管的声阻大,图象上可显示较强声影,滑动指导针,声影随之移动,这样可方便的找出最佳穿刺点(图2),提示穿刺方向及穿刺深度,然后移去探头,轻轻按压指导针使皮肤上留下痕迹,穿刺时按此痕迹进针。
This article describes the application of ultrasonic fixed point positioning method on a total of 77 cases of pleural effusion in patients with a total of 172 guiding puncture and pumping, all successful; then pumping 95 times, failed 5 times, the reason is that pleural fluid space is small, but the injection of the treatment of the smooth cavity. This group of 172 cases did not appear adverse pneumothorax injury. Methods: The use of 12 injection needle, the tip round, plastic tube jacket. Before the chest is worn, a routine examination of the affected side of the chest is performed first, and then the intercostal space suitable for the puncture is selected. The guide needle is placed between the probe and the skin (Fig. 1). Due to the large acoustic resistance of the metal tube, the image can show strong sound shadow, slide the guide needle, followed by sound and shadow move, so you can easily find the best puncture point (Figure 2), suggesting puncture direction and puncture depth, Then remove the probe and gently press the guide needle to leave a trace on the skin.
