动静脉轨道法在动脉导管未闭封堵术中的应用 总被引:1,自引:0,他引:1
目的探讨动静脉轨道法在动脉导管未闭(PDA)封堵术中的应用及技术要点。方法1998年5月至2005年7月共完成PDA封堵术831例,有11例(1.3%)患者因PDA形态特殊、开口变异不能采用常规封堵方法进行封堵,而通过建立股动脉-PDA-肺动脉-股静脉轨道法进行封堵。11例患者平均年龄(42±20)岁(8~76岁),≥35岁者8例,平均体重(61±23)kg,PDA最窄部直径平均为(4.1±1.9)mm(1.6~6.7mm)。其中10例采用圈套器在肺动脉圈套导丝建立轨道,1例因无圈套器,直接由动脉端将导丝通过PDA-肺动脉-右心室-右心房-下腔静脉-髂静脉送入6F静脉鞘管拉出体外。结果11例均成功建立动静脉轨道,其后顺利完成Amplatzer法PDA封堵术。采用封堵器(ADO)型号为6/4mm(3例)、8/6mm(4例)、10/8mm(2例)、12/10mm(1例),14/12mm(1例)。10例术后10min均达到完全封堵,1例术后10min有少量残余分流(ADO型号为14/12mm),封堵后20min重复主动脉弓降部造影,残余分流消失,11例均封堵成功。无并发症发生。结论PDA形态及开口的变异致使输送鞘管不能顺利由肺动脉侧经PDA进入降主动脉,是常规经静脉途径Amplatzer法封堵无法完成的主要原因,动静脉轨道法则能很好克服以上技术难点,且技术操作安全、有效。 相似文献

经导管封堵外科结扎术后再通的动脉导管未闭 总被引:5,自引:0,他引:5
目的:评价经导管封堵外科结扎术后再通的动脉导管未闭(PDA)的效果。方法:1995年6月至2000年11月,14例外科结扎术后再通的PDA患者进行了经导管封堵术,男5例,女9例,年龄4-48岁,平均13岁。外科手术至介入治疗的时间为1个月至22年。经股静脉途径置入Amplatzer封堵器和Rashkind封堵伞,经股动脉途径置入可控弹簧圈。分别于术后24h ,1,3,6个月及1年以上行X线胸片和超声心动图随访。结果:再通PDA为漏斗型12型,管型2例。动脉导管最窄处直径为1-8mm,平均4mm。封堵后10min,主动脉弓降部造影示无残余分流11例,微量残余分流3例。技术成功率100%,无并发症。术后24h 声心动图检查均无残余分流,所有患者均于术后1-2d出院,10例随访1-18个月,未发现封堵器移位及PDA残余分流。结论:经导管封堵外科结扎术后再通的PDA是一种有效方法,可以替代外科二次手术。 相似文献

For the military doctor, an understanding of the metabolic effects of high altitude (HA) exposure is highly relevant. This review examines the acute metabolic challenge and subsequent changes in nutritional homeostasis that occur when troops deploy rapidly to HA. Key factors that impact on metabolism include the hypoxic-hypobaric environment, physical exercise and diet. Expected metabolic changes include augmentation of basal metabolic rate (BMR), decreased availability of oxygen in peripheral metabolic tissues, reduction in VO2 max, increased glucose dependency and lactate accumulation during exercise. The metabolic demands of exercise at HA are crucial. Equivalent activity requires greater effort and more energy than it does at sea level. Soldiers working at HA show high energy expenditure and this may exceed energy intake significantly. Energy intake at HA is affected adversely by reduced availability, reduced appetite and changes in endocrine parameters. Energy imbalance and loss of body water result in weight loss, which is extremely common at HA. Loss of fat predominates over loss of fat-free mass. This state resembles starvation and the preferential primary fuel source shifts from carbohydrate towards fat, reducing performance efficiency. However, these adverse effects can be mitigated by increasing energy intake in association with a high carbohydrate ration. Commanders must ensure that individuals are motivated, educated, strongly encouraged and empowered to meet their energy needs in order to maximise mission-effectiveness. 相似文献

目的分析高原先天性心脏病心内直视手术的麻醉处理.方法术前常规禁食6 h后,给予安定、东莨菪碱行基础麻醉,待入睡后采用咪唑安定、芬太尼、仙林等静脉注射;后行气管内插管麻醉,控制呼吸频率在(16~20)次/min,调整呼吸参数.再行锁骨下深静脉穿刺置中心静脉导管,监测中心静脉压,开胸手术时应加深麻醉.结果除动脉导管未闭外,其余病例均在CPB下完成修补术,手术时间187~624 min,平均(250.67±43.26)min,CPB时间39~312 min,平均(100.23±43.26)min.588例在诱时有12%病人出现血压下降,给予多巴胺1 mg后血压回升,有99例关胸时未见血凝块,给予追加鱼精蛋白30~130 mg后,有61例主动脉开放后电击复律.所有病例在麻醉和手术过程中无急性缺氧.结论手术麻醉中必须坚持持续适宜扩容,避免右心负荷过重,纠正酸中毒和给予小剂量肾上腺素等综合措施,维持CPB乃至术后的体循环阻力的正常范围和稳定. 相似文献

Basnyat B 《High altitude medicine & biology》2002,3(1):69-71
A 35-year-old man on a trek to the Mount Everest region of Nepal presented with a sudden, acute confusional state at an altitude of about 5000 m. Although described at higher altitudes, delirium presenting alone has not been documented at 5000 m or at lower high altitudes. The differential diagnosis which includes acute mountain sickness and high altitude cerebral edema is discussed. Finally, the importance of travelling with a reliable partner and using proper insurance is emphasized in treks to the Himalayas. 相似文献

Sleep at high altitude 总被引:2,自引:0,他引:2
Weil JV 《High altitude medicine & biology》2004,5(2):180-189
New arrivals to altitude commonly experience poor-quality sleep. These complaints are associated with increased fragmentation of sleep by frequent brief arousals, which are in turn linked to periodic breathing. Changes in sleep architecture include a shift toward lighter sleep stages, with marked decrements in slow-wave sleep and with variable decreases in rapid eye movement (REM) sleep. Respiratory periodicity at altitude reflects alternating respiratory stimulation by hypoxia and subsequent inhibition by hyperventilation-induced hypocapnia. Increased hypoxic ventilatory responsiveness and loss of regularization of breathing during sleep contribute to the occurrence of periodicity. Interventions that improve sleep quality at high altitude include acetazolamide and benzodiazepines. 相似文献
