目的 探讨 Ｂ 超作为导向手段，经皮穿刺抽吸诊断、治疗周围型肺脓肿的方法及临床价值。方法 对２６ 例周围型肺脓肿病人行 Ｂ 超引导下经皮穿刺抽吸及注药治疗。抽吸物送检，做细菌培养及药敏试验。穿刺过程中对脓腔进行反复灌洗，冲洗完毕，脓腔内常规注入抗生素进行介入治疗。结果 ２６ 例病人均具备典型肺脓肿超声表现，２４ 例一次穿刺成功抽得脓液送检。其中８ 例病人根据药敏报告，调整治疗方案后，取得满意疗效。４ 例病人出现少量气胸。肺脓肿治愈率为９２ ．３ ％ 。病人平均住院２１ｄ 。结论 Ｂ 超引导下肺脓肿经皮穿刺抽吸术，具有定位准确、创伤小、安全、取得标本可靠等优点，能明显提高肺脓肿的治愈率，缩短疗程，有较高的临床实用价值。
Objective To investigate the method and clinical value of B-ultrasound as a guiding method and percutaneous aspiration for diagnosis and treatment of peripheral pulmonary abscess. Methods Twenty-six patients with peripheral pulmonary abscess underwent percutaneous aspiration and injection under the guidance of B-ultrasound. Aspirate submission, bacterial culture and drug susceptibility testing. During the puncture, the abscess cavity was repeatedly lavaged and the rinsing was completed. The abscess cavity was routinely infused with antibiotics for interventional therapy. Results Twenty-six patients had typical pulmonary abscess ultrasonographic findings. Twenty-four patients were successfully punctured with pus. Among them, 8 patients achieved satisfactory results after adjusting the treatment plan according to the drug sensitivity report. 4 patients showed a small amount of pneumothorax. The cure rate of lung abscess is 92. 3%. The average patient hospitalized 21d. Conclusions B - ultrasonography guided percutaneous aspiration of pulmonary abscess has the advantages of accurate positioning, small trauma, safety and reliable specimens. It can significantly improve the cure rate and shorten the course of treatment of pulmonary abscess, and has a high clinical value.
