  • 简介:目的探讨复杂性视网膜脱离术后疼痛与舒适护理对策。方法选取我院于2015年9月-2016年6月行复杂性视网膜脱离术的136例视网膜患者的临床资料,按照随机盲选的方式进行分组,分别为观察组和对照组,两组各有68例患者,采用视觉模拟评分法对患者术后的疼痛程度及疼痛原因进行评估,并选择恰当的护理对策。结果对照组患者术后疼痛发生率为58例,轻度、中度、重度疼痛级别分别为43例、10例、5例;观察组患者术后疼痛发生率为42例,轻度、中度、重度疼痛级别分别为16例、20例、6例,对照组患者的术后疼痛程度明显高于观察组患者,两组术后疼痛及疼痛程度对比,差异具有统计学意义(P〈0.05)。结论减轻患者术后疼痛,在使裂孔处于最高位的基础上,对体位的适当调整,能够提高患者术后舒适程度。

  • 简介:目的:分析最小量节段性外垫压手术治疗复杂原发性视网膜脱离的效果和手术并发症。方法:回顾性分析2006-10/2008-10在西安市第四医院眼科住院的、接受最小量节段性外垫压术治疗的连续的复杂原发性孔源性视网膜脱离76例。复杂原发性孔源性视网膜脱离限定为裂孔位于两个及两个以上象限,玻璃体视网膜病变分级在C1~C2。最小量节段性外垫压术是指仅限于裂孔区的节段性外垫压,联合前房穿刺放房水,术后裂孔周围激光凝固。分析其发病年龄、病程、手术前后视力、视网膜脱离范围、裂孔数目、裂孔形态、一次手术复位率、再次手术复位率、再次手术率及术后并发症,并行统计学处理。结果:患者发病年龄平均31.92(19~62)岁,平均病程为7.40(2.0~36.5)mo,视网膜脱离象限平均为3.33个,平均裂孔数量为3.43(2~7)个。手术后视力提高的患者为48例,一次手术复位率是84%(64/76);再次手术复位率是93%;再次手术率为38%。术后并发症包括:术后短期复视3例,短期高眼压12例,黄斑水肿2例,共17例。结论:和文献资料比较,以最小量手术治疗复杂原发性视网膜脱离可以取得与环扎手术同样的解剖及功能复位,但是再次手术率较高。强调手术适应证选择的重要性。
