Holding the surgical retractor, Zhang Shuping carefully helped Mr. Xie pull the surgical incision, and held his breath together with the emergency nurse who was assisting. I just remember that the textbook said that if you want to touch the pericardium at the wrong angle, you may encounter obstacles or feel awkward to operate. If the external pericardial compression is unsuccessful, you need to disconnect the third and fourth ribs at that time.
Compressed within the pericardium. At that time, it will be a dead horse as a living horse doctor.
Best, preferably a one-off performance hit. Zhang Shuping deeply felt that the heat he exhaled would burn him to death.
The current situation is really a hot potato for him and Mr. Xie.
I don't want to save it, but the success rate of this kind of dead horse as a living horse doctor is too low.
This is also the reason why external cardiac compression is commonly advocated in clinical practice, while internal chest cardiac compression is extremely rare. According to medical statistics, there is no advantage in the success rate of internal chest compressions compared with external chest compressions. Therefore, there are special prerequisites for the doctor to perform intrathoracic cardiac compression on the patient. As in the current case, as in
Shou'er has seen patients who have undergone thoracotomy and left the chest cavity unclosed for sudden rescue.
Swish, Chief Surgeon Xie put his gloved right hand into the surgical incision. She has never done this kind of surgery independently, but she must have done chest compressions, otherwise she would not have dared to do it without saying it. I remember the dish that was given by the fairy brother in Seoul, which made her madly give the little baby
Do heart compressions with bare hands.
After being tempered by such a worse encounter, her mentality is undoubtedly stable at the moment.
Thanks to the group of "ruthless and ruthless" mentors like Brother Shenxian for leaving her with all kinds of painful experiences and lessons. After touching the patient's heart surrounded by the pericardium, the first step is not to press, but to further confirm the diagnosis: the patient's heart has stopped beating completely, or the heartbeat is weak, that is, the heart beats weakly and has little strength, or is in the
Ventricular fibrillation? If the heartbeat is weak, it should be combined with intracardiac injection of 0.1% epinephrine or 10% calcium chloride to stimulate the myocardium before performing cardiac compressions.
Help maintain blood pressure. If it is ventricular fibrillation, it is not necessary to perform electrical defibrillation immediately, but to wait for the myocardial tension to improve after performing cardiac compressions for a certain period of time before performing defibrillation. It can be seen that the most professional medical heart compression is not taught to laymen before the hospital
Rescue is as simple as doing compressions, and it needs to cooperate with precise first aid measures such as rescue medication.
After carefully touching the patient's heart, Xie Wanying was sure: it was arrest. Is it scary to stop fighting completely? Seems to be the worst of the three cases above. But in either case, neither is good for doctors until the heart is fully back beating normally. Patient's
Heart conditions are changing rapidly, and the three conditions may be interchangeable.
What doctors have to do is to implement routine operating procedures step by step and follow the valuable clinical experience left by countless medical predecessors to younger generations.
The gloved right hand immediately moves further into the compression position.
There are three methods of intrathoracic cardiac compression, one-handed and two-handed and compression of the sternum.
The one-handed technique is to touch the front of the patient's heart with the thumb and thenar, and place the other 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 heart's main pumps responsible for outputting blood. If the heart stops beating, the pumping function of the ventricles will be lost, and the heart itself and other organs of the human body will lose blood nutrition and be killed together. This is exactly what heart compressions are designed to solve.
