How to implement the lung artery one is narrow to treat surgery
Lung artery one narrow at intermediate low-temperature generally in the past ' 30- 32 ) Implement ocular to depend on membrane juncture cut skill, low-temperature way simple and convenient, one that is to physiological efficiency under body confused and less, resume smoothly while being postoperative, but because low temperature only can supply, circulate, block 6- 8 minutes such as time limit safely, must finish to operate hurriedly hurriedly in the heart, and does not have rich time to ascertain and correct and manage the deformity in the heart. Extracorporal circulatory system becoming better and approaching perfection day by day in recent years, myocardium protection and the intersection of operation and progress of technology make in the heart regarding performing the operation as safe direct, therefore lung the intersection of artery and the intersection of mouth and narrow operation adopt extracorporal circulatory system generally direct-view correct cure skill in the lower heart.
The extracorporal circulatory system makes direct-view and corrects and manages the skill: Suitable for all kinds of lung the intersection of artery and the intersection of mouth and narrow treatment, patient body posture, chest cut-out and the intersection of heart and trunk dissect step, look surgery straight at low temperature, until the intersection of 3mg/kg and Heparin take, aorta insert artery in pour into, in charge of, and atrium dextrum distinguish insert up and down the intersection of vena cava and drainage tube in through right auricle of heart on rise, the blood of beginning lowers the temperature after setting up extracorporal circulatory system, according to heart efficiency state and pathological change miscellaneous intensity, until nasopharyngeal temperature, patient of worry, lower first, aorta hinder bring up the rear, rise aorta root fast to inject the cold heart into, park, fight liquid, the pericardium is poured with frozen water, the surface of heart lowers the temperature and protects the cardiac muscle with the part of the little ice bag, then block the up and down vena cava around taking, cut the intersection of lung and artery or right room, implement the intersection of lung and the intersection of artery and petals of the intersection of direct-view and lower juncture, cut skill and/or the intersection of funnel and parts of plump muscle, excise skill, flow out line expand, mend slice come on.
Funnel part is plump it excise muscle, should wrap up pregnant to separate on bunch, among bunch and ridge dirt muscles plump in some room, the plump meat column should be excised, in order to dredge and flow out one, but need to avoid cutting off the skin of papilla, taper skin in the vicinity and regulating bunch in the heart, flowing out a diameter adult and should be greater than 1.7cm after dredging, children should be greater than about 1.4cm, otherwise should wrap up one to cut out and mend slice in order to expand and flows out one as a shuttleless loom shape intentionally, a ring of narrow and small lung artery should also be cut until the right room flows out one, then expand by weaving slice or pericardium slice. Step petals of ring, mend block, will produce the intersection of lung and the intersection of artery and petal, close completely, might it produces right rooms to be depleted while being postoperative. Can't close completely in order to avoid producing the serious lung artery one, spend postoperative critical days safely, admissible to take a leaf and mend one and expand a ring of lung artery, avoid leading to the fact the lung artery one can not be closed completely because a ring is expanded. Skill finish right room and the intersection of aorta and the intersection of root and part distinguish, insert needle rank angry, the open aorta blocks pincerses, shocking by electricity if necessary quiverly makes the heart reply and beat. Wait to reply warmly to 35 , the extracorporal circulatory system of winding up after the heartbeat is stabilized with blood pressure effectively, successively pulled out up and down vena cava intubate and artery to pour into and manage, instilled in order to neutralize Heparin according to fish's precise albumen 4.5cm vein of per kilogram of weight.
The intersection of lung and the intersection of artery and mouth is narrow to treat the postoperative complication of surgery
Postoperative complication, there are two points primarily except looking complication which may cause in the heart in operation straight in general extracorporal circulatory system: First after it is removed that the intersection of lung and the intersection of artery and mouth is narrow, the blood capacity of circulation of lung obviously increases, so should fill the blood capacity appropriately according to arterial pressure and central venous pressure, in order to prevent postoperative low heart from arrange the intersection of blood and disease, vein instil dopamine and the west inside strong heart such as being blue step up medicine if necessary, in order to strengthen the cardiac muscle to compress strength, the transition is firm to dynamics of blood flow. Second if flow out one is too narrow to remove completely, the right room is still tall in pressure, it is postoperative apt to cause the right room to cut-out and bleed, and apt to produce the right heart depletedly.
