Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 2447 [2447] Well done

  If you look at the anatomical map, you will find that the posterior superior iliac spine is larger than the bone plane of the anterior superior iliac spine. The bone plane is large, and it is easier to implant when the needle tip falls. Unlike the small bone plane, the needle tip falls like the needle tip is facing the wheat awn, which is easy to wipe and difficult to achieve vertical needle insertion.

   Vertical needle insertion is important. The bone penetration itself is to be inserted into the bone, and the bone is hard, which means that it is laborious. Inserting the needle vertically is like hammering a nail with a vertical force that is easy to enter.

   In clinical practice, some bones that are not easy to wear are common. When the clinical teacher is piercing, the expression of the teacher who drills the bone will be hard. This kind of force is not only laborious but also afraid of overexertion. For the first time, Zhang Desheng was not afraid of death, but he dared to start drilling hard all of a sudden. If the needle can't be inserted vertically or pierced, the psychological frustration of the novice is far less than that of the veteran who will collapse instantly.

   Secondly, in clinical practice, the bone marrow dilution rate of bone marrow extraction is quite high. What is bone marrow dilution, that is, no bone marrow can be drawn or too little bone marrow is drawn, and most of the samples drawn are blood. Such specimens sent to the laboratory for bone marrow examination must be unqualified and must be redrawn, which is equivalent to failure of bone puncture.

   If the question is the posterior superior iliac spine, the child needs to fall asleep on his stomach, which will inhibit breathing to a certain extent. Perhaps based on this consideration, Zhang Desheng did not dare to choose the posterior superior iliac spine. Mainly, the child's parents are too difficult to deal with, and they dare not take the risk by asking the doctor.

   Do not allow the child to be placed in the prone position. Another method is to expose the posterior superior iliac spine by having the child lie on the side with both knees clasped. This position is not very stable. For this reason, Zhang Desheng respected Xie's opinion.

   It may be a little difficult to get a good posture, but it is better than when the anterior superior iliac spine is not pierced as Xie said, and the needle is swung in the middle for a long time, and the consequences will be even greater.

  There are classmates to help, so there is no need to be too afraid.

   reported to Teacher Tian that the posterior superior iliac spine was chosen, and Teacher Tian and Teacher Wang agreed.

   Several classmates began to help the child adjust his posture. Two other surgical students saw this and came up to help.

   Carefully change the child to the side lying position, and control the movement of the joints when controlling the child, instead of pressing **** the child.

   The location is said to be the posterior superior iliac spine, but in fact the puncture point is the protrusion between the posterior superior iliac spine and the fifth lumbar vertebra.

   After changing the position of the child, Zhang Desheng felt something different. The gloved hand can feel the relatively flat bone surface, which means that this position exposes the bone position to be operated well. It's not like when he first touched the anterior superior iliac spine, what he felt was just a bulge and it was difficult to insert the needle.

   contacted that the child’s current position was put by classmate Xie. Zhang Desheng praised in his heart: Xie is amazing.

  Being able to touch a wide range of good acupuncture points, the doctor's confidence is naturally much more abundant.

  Zhang Desheng then worked his way up, hitting the periosteum with anesthesia with high precision, so he could do it at his fingertips. After pressing the area where the local anesthesia was finished, when the needle was placed again, because of the confidence, the bone piercing needle was pierced straight down, and as soon as the plunger of the syringe was pulled, something came up. The process was incredibly smooth.

  The doctor moves quickly, and the pain and discomfort of the child will definitely be relieved a lot. Like adults, children are most afraid of long pain.

   Seeing that the students had taken out the marrow in three or two strokes, the two supervising teachers nodded sharply: These students did a good job, and they did not need the teacher's guidance to do it themselves.
