单向式胸腔镜肺叶切除术手术配合及护理

【摘要】 目的 总结单向式胸腔镜肺叶切除的手术配合及护理要点。 方法 2006年5月-2008年6月对48例行单向式胸腔镜肺叶切除术患者的治疗及手术护理方法，注重做好术前器械物品的准备、胸腔镜特殊器械的消毒、手术体位的最佳放置和术中护理配合等工作。 结果 48例患者在全腔镜下顺利完成手术，术中无并发症发生，无围术期死亡。全组手术时间70～260 min，平均164 min；术中出血100～500 mL，平均138 mL。 结论 术前充分的准备和术中密切配合是患者疾病获得治愈的重要保证。

Fundus fluorescein angiography in retinopathy of prematurity

ObjectiveTo analysis the fundus characteristics of fundus fluorescein angiography (FFA) of retinopathy of prematurity (ROP). MethodsEighty-four cases (168 eyes) who were diagnosed with ROP by a binocular indirect ophthalmoscope were included in the study. Among the 84 cases, there were 2 cases (4 eyes) of stage 1 ROP, 26 cases (52 eyes) of stage 2 ROP, 40 cases (80 eyes) of stage 3 ROP, 4 cases (8 eyes) of stage 4 ROP, and 4 cases (8 eyes) of stage 5 ROP, 9 cases (18 eyes) of plus disease, 8 cases (16 eyes) of aggressive posterior ROP (APROP). All infants received FFA with RetCam Ⅱ under general anesthesia and mydriasis. The retinal vein morphology, capillary filling state, neovascularization morphology and fluorescein leakage were observed. ResultsFFA revealed increased branching, expansion and tortuous peripheral retinal capillaries, increased capillary permeability with a small amount of fluorescein leakage in stage 1 ROP. There was a clear dividing line between the vascular area and the remote avascular area. In stage 2, the peripheral branches of temporal retinal blood vessels increased, and parallel distributed like a broom. The capillary end anastomosed with each other to form a loop. The fibrous tissues at the lesion edge proliferated as a ridge, with popcorn phenomenon. In stage 3, the ridge continued broadening, and the neovascular fibrous membrane formed breakthrough internal limiting membrane, stretched into the vitreous with a lot of fluorescein leakage. The ridge and remote avascular zone demarcated clearly. In stage 4 and 5, the vessel changes had similar phenomenon with the stage 2 and 3 in undetached retina, but the vessels in the detached retina expanded with fluorescein leakage. As for plus disease, the retinal arterioles in the posterior pole were tortuous, there were a large number of non-perfusion area in the peripheral retina with hemorrhage and obscured fluorescence. The retinal vessels in posterior pole in AP-ROP were also tortuous, and the capillaries were extreme expanded, while there were very few tortuous vessels and no capillary formation in the other part of retina.At the avascular zone boundaries, there were a large group of neovascularization with fluorescein leakage. ConclusionsThe demarcation line separating the avascular from the vascularized retinal regions is formed in stage 1, 2 and 3, and the amount of fluorescein leakage gradually increase from stage 1 to stage 3 ROP. The detached retina of stage 4 and stage 5 has an unclear focal length in the FFA. The plus disease mainly has arteriolar tortuosity in the posterior pole retina. In the AP-ROP cases, both of the arterioles and venules in posterior pole of retina are tortuous and expanding with neovascularization leakage of fluorescein.
