【摘要】 目的 分析四手操作护理技术于根管显微镜下取出断针的应用成功率。方法 98例根管内断针的患者， 按护理操作方式不同分为对照组和观察组， 各49例。对照组行常规护理， 观察组行四手操作护理， 对比两组断针取出成功率及护理满意度。结果 观察组上颌前牙、双尖牙及下颌后牙、双尖牙断针取出成功率分别为100.00%、94.59%、97.37%、81.25%， 均高于对照组的77.78%、71.43%、83.33%、55.00%， 差异均具有统计学意义（P<0.05）。观察组护理总满意度为91.84%， 高于对照组的73.47%， 差异有统计学意义（P<0.05）。结论 在根管显微镜下取出断针的手术中应用四手操作护理技术的成功率高， 可有效取出根管内断针， 并提高患者满意度， 值得推广。

Analysis on success rate of four-handed operation nursing technique in taking out broken needles by dental operating microscope LIN Li-e. Foshan City Stomatological Hospital， Foshan 528000， China

【Abstract】 Objective To analyze the success rate of four-handed operation nursing techniques in taking out broken needles by dental operating microscope. Methods A total of 98 patients with broken needles in root canal were divided by different nursing operation methods into control group and observation group， with 49 cases in each group. The control group received routine nursing， and the observation group received four-handed nursing. Comparison were made on success rate of broken needles taking-out and nursing satisfaction degree in two groups. Results The observation group had success rate of broken needles taking-out in maxillary anterior teeth and bicuspid， mandible posterior teeth and bicuspid respectively as 100.00%， 94.59%， 97.37% and 81.25%， which were all higher than 77.78%， 71.43%， 83.33% and 55.00% in the control group， and the difference had statistical significance （P<0.05）. The observation group had higher total nursing satisfaction degree as 91.84% than 73.47% in the control group， and the difference had statistical significance （P<0.05）. Conclusion Four-handed operation nursing technique provides higher success rate in taking out broken needles by dental operating microscope， and it can effectively take out the broken needles in root canal and increase the satisfaction degree in patients. So it is worth promotion.

牙髓病、根尖周病等口腔牙病的臨床治疗以根管治疗为主， 但在预备根管时， 特别是细小弯曲的根管， 由于预备根管器械用时长， 加之根管频繁消毒而加速老化， 亦或医生操作不当或缺乏经验， 易折断根管器械[1-3]。若根管器械近根尖处折断， 则从根管中取出器械较难， 临床医生亦难以处理。为提高根管内断针取出成功率， 本院采取四手操作护理技术应用于根管显微镜下断针取出， 并以2014年11月～2016年3月本院口腔科98例根管断针患者为研究对象进行分析， 现报告如下。
