声振动疗法在喉癌术后止痛护理中的应用

目的提高静脉留置针穿刺困难者的一次穿刺成功率。方法将200例需行静脉留置针穿刺的患者随机分为对照组和观察组，各100例。对照组按常规穿刺，观察组采用负压技术穿刺，即将容量为2ml的吸球和三通接头接上留置针．使之穿刺时形成负压，再行穿刺。结果两组静脉穿刺回血率、一次成功率比较，差异有显著性意义（X^2=18．32、27．56，均P〈0．01）；留置针保留时间比较，差异无显著性意义（P〉0．05）；两组颈外静脉、大隐静脉穿刺回血率、一次穿刺成功率比较，差异有显著性意义（X^2=18．26、18．26、5．00、5．00，P〈0．01或P〈0．05）；两组股静脉一次穿刺成功率比较，差异有显著性意义（P〈0．01）。结论负压技术可提高留置针穿刺回血率和一次穿刺成功率。

Application of Negative Pressure Technique in Indwelling Needle Vein Puncture

Objective To investigate the pai n relieving effect of vibroacoustic therapy on patients with laryngeal cancer afte r surgery. Methods A total of 87 patients were divided randomly into two groups:an experimental group (n=45) and a control group (n=42). The control group was given routine nursing care and the patients in the experi mental group were treated with vibroacoustic therapy from the 2rd day after oper ation (once per day, 30-60 min each time). The pain relieving effects in the 3rd , 5th and 7th day were compared. Results The effective rate of p ain relief in the experimental group was 53.3%,77.8%,95.6% and 26.2%,33.3 %,71.4% in the control group, respectively and the differences in the effecti ve rates between the two groups were statistically significant (P<0.01, for all). No adverse effects were observed. Conclusion The vibroaco ustic therapy is safe and better than the routine method in terms of pain reliev ing effect for patients with laryngeal cancer after surgery.
