    Holding the surgical retractor, Zhang Shuping carefully helped Teacher Xie pull the surgical incision while holding his breath with the assisting emergency nurse.  I just remember what the textbook said, if the angle of penetration is wrong and you want to touch the pericardium immediately, you may encounter obstacles or the operation will be awkward. If the external pericardial compression is unsuccessful, you will need to disconnect the third and fourth ribs at that time.

    Intrapericardial compression.  At that time, it will be a dead horse and a living horse doctor.

    The best, the best is a successful performance the first time.  Zhang Shuping felt that the hot breath he breathed was going to burn him to death.

    This situation is really a hot potato for him and Teacher Xie.

    ??It¡¯s impossible to save even if you don¡¯t want to, but the success rate of treating a dead horse as a living horse is really low.

    This is the same reason why clinical routine advocates external chest cardiac compression while intrathoracic cardiac compression is extremely rare.  According to medical statistics, there is no advantage in the success rate of intrathoracic heart compression compared to external chest heart compression.  Therefore, there are special prerequisites for doctors to perform intrathoracic heart compressions on patients.  Such as current cases, such as in

    The first time I saw a patient who had undergone thoracotomy and the chest cavity was not closed after surgery, he was rescued suddenly.

    ¡°Swish, Surgeon Xie¡¯s gloved right hand reached into the surgical incision.  She has never done this kind of surgery independently, but she must have done intra-chest heart compression, otherwise she would never have dared to do it as she said.  She once remembered the trick she was put in by the fairy brother when she was a child, which made her crazily give the little baby

    Perform heart compressions with bare hands.

    After experiencing such a worse encounter, her mentality is undoubtedly very stable now.

    Thank you to Brother Shenxian, a group of "cruel and ruthless" mentors for leaving her with all kinds of painful experiences and lessons.  After touching the patient's heart wrapped by the pericardium, the first step is not to press, but to further clarify the diagnosis: the patient's heart has completely stopped, or the patient's heart is simply weak, that is, the heart beats weakly and has no strength, or the patient's heart is beating weakly and without strength.

    Ventricular fibrillation?  If the heartbeat is weak, 0.1% epinephrine or 10% calcium chloride should be injected into the cardiac cavity to stimulate the myocardium and then cardiac compressions should be performed. At the same time, a medical order should be issued for the nurse to inject dopamine and other auxiliary drugs into the intravenous channel.

    Helps maintain blood pressure.  If it is ventricular fibrillation, it is not necessary to perform defibrillation immediately. Instead, after performing heart compressions for a certain period of time, wait for the myocardial tension to improve before performing defibrillation.  It can be seen that the most professional medical cardiac compression technique is not taught to laypeople in the pre-hospital scene.

    A simple rescue operation such as compression must be accompanied by precise first aid measures such as administering rescue medicine.

    After carefully touching the patient's heart, Xie Wanying was sure: it was asystole.  Is it scary to have complete cardiac arrest?  It seems to be the worst of the three situations above.  But no matter what the situation is, for doctors, it is not necessarily good unless the heart completely returns to normal beating.  patient's

    Heart conditions are ever-changing, and the three conditions may be interchangeable.

    What doctors have to do is to carry out routine operating procedures step by step and follow the valuable clinical experience left by countless medical predecessors to their descendants.

    The gloved right hand immediately further prepares the compression position.

    There are three methods of intrathoracic heart compression, one-hand method, two-hand method and sternum compression method.

    The single-hand method is to touch the front of the patient's heart with the thumb and thenar eminence, and place the remaining four fingers behind the patient's heart. The purpose is to press the left and right ventricles evenly, forcefully and rhythmically.  The left and right ventricles are the main pumps of the heart and are responsible for pumping blood.  When the heart stops beating, the ventricles lose their ability to pump blood, causing the heart itself and other organs in the body to lose blood nutrients and die.  This is exactly what cardiac compressions are designed to solve.  (Remember the website address: www.hlnovel.com
