The lung artery one is narrow to cut the _ prevention and health care of attentive matters in the skill skill
1.Ventricle fine and quiver prevention and treatment See more at low temperature looking the intersection of lung and the intersection of artery and petal straight, cutting body temperature drop too low in the skill ' Under 28 ) ,The cardiac muscle is damaged, the lung is insufficient in air exchange amount, myocardium oxygen deficiency, hypotension and electrolytic acid-base balance disorder,etc.. Once happening should press the heart immediately, the Epinephrine of injection in the heart, strengthen and support oxygen, accelerate blood transfusion, improve blood pressure and such as the hypothermia, pour into warm brine of 38 to reply in the pericardium warmly. When the ventricle is fine and quiver effectively, shocking by electricity can succeed to defibrillate. The method that prevents from is that the body surface don't be lowered too low while lowering the temperature, are generally cooled to 33 - block and circulate at 31 , the not incident room is quiver. Paid attention to improving blood pressure before blocking the blood flow, excessively took a breath, made the cardiac muscle have a good stocking the function, in order to tolerate temporary myocardium oxygen deficiency. Should try hard to shorten the blood flow and block time. Lower vena cava open hour should not be too early, in case that it caused the room quiverly that the heart swelled suddenly. 2.Block the extracorporal circulatory system of cycle time and play the operation, it is unrestricted to block cycle time, have abundant time to finish the operation. And when hypothermic anesthesia looks the operation straight, blocking cycle time generally can't exceed 8 minutes, in case of special difficulty need, lengthen, block time, can mention all draw the line first, the temporary pincers closes the lung artery to cut-out, the open up and down vena cava blocks bringing, when the heart resumes the good state, block and circulate again, finish the operation. But should try hard to shorten and block cycle time. 3.Valve mouth cut off intensity cut to the intersection of valve and base according to the intersection of valve and juncture, adult pass the intersection of skill person and index finger smoothly, child thinks promptly satisfied through the little finger of toe. Cut off a petal of ridge and adhere to the artery wall, can expand a area of the valve. Pay attention to avoiding cutting the artery wall of broken lung, sew up such as cutting broken application Line 3-0. 4.One is narrow to amalgamate odd-shaped treatment lung artery one narrowly and often amalgamate the right ventricle funnel, can with small to draw hook, pull open the lung artery one to appear in the narrow position, excise its loose skin bunch. If funnel one is narrow and serious, Shang Ke cuts the right ventricle, excises the loose skin bunch, can also flow out one on the right room and use to mend one to widen. If it is very difficult to deal with in the above-mentioned situation, but does not have more misgivingses while circulating the operation outside the body, so a narrow majority of lung artery adopts the extracorporal circulatory system to play the operation at present.
