目的探讨如何减少Ｂ超引导下经皮肝穿刺注射无水酒精（ＰＥＩ）疗法的并发症。方法总结３０例１５２例次ＰＥＩ治疗成功的经验和术前、术中、术后的注意事项。结果本组一次穿刺成功率高，为９７．４％，不良反应少，无严重并发症。疗效较好，８７％患者疼痛缓解，７４％的瘤体有缩小，５７％患者 ＡＦＰ定量检查明显下降。 １，２ ａ生存率分别为 ２８％及６％。结论要减少ＰＥＩ治疗的并发症就要严格掌握ＰＥＩ的禁忌证和适应证；术前须对患者进行控制呼吸训练；Ｂ超和穿刺器械要匹配，术前须重新调较，严格消毒；术中Ｂ超定位引导要准确、稳定，穿刺技术要熟练，注药要慢；术后要做好局部压迫和护理监测工作，发现问题及时处理以防治严重并发症。
Objective To explore how to reduce the complications of percutaneous transhepatic injection of anhydrous alcohol (PEI) guided by ultrasound. Methods The experience of successful treatment of 152 cases of PEI in 30 cases and preoperative, intraoperative and postoperative considerations were summarized. Results The success rate of this group of punctures was high, 97.4%, less adverse reactions, no serious complications. Efficacy is better, 87% of patients with pain relief, 74% of the tumor has narrowed, 57% of patients AFP quantitative examination decreased significantly. 1,2 a survival rates were 28% and 6%. Conclusion To reduce the complications of PEI treatment, it is necessary to strictly control contraindications and indications of PEI. Patients should be trained to control respiratory training before surgery. B-ultrasound and puncture instruments should be matched before operation and be sterilized strictly. B-positioning guide to be accurate and stable, puncturing techniques to be skilled, slow injection; to do a good job of local oppression and nursing monitoring, timely detection of problems to prevent serious complications.
