  The nurse came over to inform the doctor that the patient\'s family had arrived.

  Cheng Yuchen asked a young resident doctor, Dr. Wang, to go out to communicate with his family, and signed the informed consent form for the operation. At the same time, since a hydropneumothorax is suspected, it is inevitable for the patient to do CT.

   It takes time for the CT film to be released, and the medical staff will pay close attention to the preoperative preparations during this period. This procedure only needs to be performed at the bedside and does not require entering the operating room unless the patient\'s condition changes along the way.

   "Wear gloves." As his own application for guidance, Dr. Cheng Yuchen gave instructions to the operating classmates.

  The students of the capital were waiting in a circle around the periphery, their gazes like torches that were ready to pick on them at any time.

   The hearts of several national synergists were pounding: Classmate Xie went deep into the enemy camp the day before to prepare for a duel.

   asked them, Zhao Zhaowei, to say that the most "bad" person was Mr. Cao, the devil, and he had to be specially banned from the very beginning.

   The patient is a little nervous. Children in this age group are half-sensible and half-adults, with immature psychological construction, and the sudden outbreak of panic cannot be ignored.

   "Don\'t worry, it\'s like an injection, it doesn\'t hurt." Xie Wanying said to her little sister.

In front of   , this elder sister has beautiful big eyes. If a little girl is dreaming: Did she come to the hospital one day today to see a star?

   Don\'t you mean to insert a big tube? How do you say it\'s like an injection?

   Dr. Cheng Yuchen coughed and cleared his throat to remind the classmates: No need to comfort him. At that time, if the operation time is too long, the patient will become suspicious and even worse. Children will cry if they are not as strong as adults.

   Whether the doctor\'s comfort is effective depends on the technique behind. Otherwise, it would be self-defeating to say more comforting words.

  Senior is right. Xie Wanying only said a word.

   The operator and assistant are prepared separately.

  Like other puncture procedures, after positioning, sterilize and lay the sheets.

   There are several options for the puncture site for a pneumothorax. The most common one is the second intercostal space on the midclavicular line that Xie did before, where the needle is inserted into the anterior chest wall of the patient. If it is fluid, usually the mid-axillary line and the posterior axillary line are chosen. Liquids are not like gases, water naturally flows down the human body is universal.

   The trouble of hydropneumothorax is that a large amount of hydropneumothorax is easier to pump, and a small amount of hydropneumothorax is difficult to pump.

   The results of the CT scan showed signs of thickening of the pleura, and the visibility of the effusion on the instrument is not clear enough at this stage.

   Dr. Cheng Yuchen didn\'t want to help the patient to extract the fluid by the way, and it must be more comfortable to extract the fluid. The question of whether this limited effusion can be pumped is likely to be mucus, which is really a skill.

   It is normal for medical students to not be able to pump gas. Thank goodness for medical students as long as they can pump gas. Therefore, some medical students are ignorant of the sky and imagining that the big brother can solve all the problems of the patient in one step. No clinical teacher dared to think so easily.

   Xie has fixed the position and is ready to cut the knife under the mid-axillary line.

   Dr. Cheng Yuchen, as his boss thought, was waiting to see who was the last to overturn.

   The nurse cooperated, and the chief surgeon picked up the syringe and sucked the local anesthetic mixed with normal saline, then turned around, and the needle tip sank into the patient\'s skin in a blink of an eye.

   Her movements were too fast, and the people in Guodu who had never seen her operate lost their eyes in amazement.
