ObjectiveTo evaluate the short-term result of proximal lengthening grafted stent and modified innominate artery cannula for Stanford A aortic dissection. Method We retrospectively analyzed the clinical data of 21 patients with Stanford A aortic dissection in our hospital between December 2012 and January 2015. There were 16 males and 5 females at a mean age of 57 years. All 21 patients underwent total arch replacement with proximal lengthening grafted stent and modified innominate artery cannula invented by our center. Result The mean operation time of 21 patients was 187.0±31.1 minutes, the mean cardiopulmonary bypass time was 116.0±32.0 minutes, the mean aortic block time was 87.0±23.0 minutes, the mean selective cerebral perfusion (SCP) time was 23.0±3.9 minutes, the mean breathing machanical ventilation time was 19.0±6.0 hours, and the mean intensive care unit stay time was 3.0±0.9 days. All patients had a good recovery after surgery. There was no death or severe complications. ConclusionThe technique of total arch replacement with proximal lengthening grafted stent and modified innominate artery cannula for Stanford A aortic dissection is effective, easy, and safe. The short-term result is satisfying.
目的:觀察等效劑量瑞芬太尼和芬太尼誘導氣管插管對小兒血流動力學的影響。方法:40例擇期行全麻患兒隨機分為瑞芬太尼組和芬太尼組,麻醉誘導使用咪唑安定0.15mg/kg、丙泊酚2.5mg/kg、芬太尼2.5μg/kg或瑞芬太尼2μg/kg和維庫溴銨0.1mg/kg。分別于麻醉誘導前(T0)、誘導后2min(T1)、插管后1、2min(T2、T3)記錄心率、收縮壓和舒張壓。結果:兩組誘導前血流動力學指標相似。與T0時比較,兩組患兒T1時收縮壓、舒張壓均降低(Plt;0.05或Plt;0.01),心率均減慢(Plt;0.05或Plt;0.01);瑞芬太尼組T2.T3時收縮壓、舒張壓降低(Plt;0.05或Plt;0.01),心率減慢(Plt;0.05);芬太尼組T2、T3時收縮壓、舒張壓升高(Plt;0.05),心率增快(Plt;0.05)。與芬太尼組比較,瑞芬太尼組T1、T2和T3時收縮壓、舒張壓均降低(Plt;0.05),心率減慢(Plt;0.05)。結論:瑞芬太尼比等效劑量芬太尼能更好地抑制小兒全麻誘導氣管插管時的心血管反應。
ObjectiveTo investigate the therapeutic effects of thrombolysis infusion via microcatheter on the treatment of central retinal artery occlusion(CRAO). MethodsUrokinase (UK) was directly infused via ophthalmic artery (OA) by microcatheter (6 patients) or via intravenous (7 patients) to dissolve the thrombus. The patency of the artery was evaluated by fundus fluorescein angiography (FFA), and the effect of fibrinolytic activity on the systemic changes was observed by blood biochemical examination simultaneously. ResultsIn 6 patients in the microcatheter group, 5 had completely and 1 had partly reopened OA on the morrow of UK infusion with the patency rate of 83.33%, while in 7 patients in vein group, 3 completely reopened, 2 partly reopened and 2 obstructed OA were found with the patency rate of 42.86%. The difference between the two groups was significant. No obvious change of index of blood coagulation system was found in catheter group, which had great disparity compared with the vein group.ConclusionUrokinase infusion via microcatheter in CRAO has better therapeutic impact and smaller effect on systemic action.

目的：比較常規鼻胃管置入法與鼻咽部局部噴霧麻醉后置胃管法對喉癌患者的影響。方法：將需要安置胃管的100例患者隨機分成兩組，每組50例。實驗組行鼻咽部噴霧麻醉，對照組按常規操作，比較兩組患者流淚、惡心、嘔吐、咳嗽反應，一次成功率及插管所需要時間、插入中暫停次數。結果：實驗組一次成功率高，患者反應輕，插管所需時間有顯著差異。結論：常規置胃管常因病員難受而中途暫停置管，實驗組置胃管前先作鼻咽部局部噴霧麻醉，可明顯減輕患者的痛苦，提高插胃管的一次成功率，插管過程中因病員難受暫停次數也明顯減少，使臨床護理工作時間縮短，對臨床護理工作有積極意義。
