Pediatric broken finger reimplantation is a kind of surgery for special people. Pediatric broken finger reimplantation is an emergency surgery, the following issues should be noted: 1. Pay attention to the preparation before anesthesia: The psychological state of the child is unstable and unfavorable to anesthesia, therefore, the visit should be amiable and gain the trust of the child and its parents. Fasting time, solid food for 6-8 hours, clear liquids for 2 hours, preoperative medication is injected intramuscularly before anesthesia. 2, pay attention to the intraoperative tourniquet pressure: the pressure should not be too high in children, depending on the diameter of the upper arm in children, the pressure is generally 30-35kPa for no more than 1 hour to avoid causing injury to the brachial plexus nerve. If the broken finger is not near the node, a tourniquet may not be placed on the upper arm, and a leather band may be placed on the root of the finger. Release the tourniquet slowly and do not release it suddenly to cause blood pressure changes. 3. Pay attention to the accuracy of axillary brachial plexus nerve block: The operation of finger replantation needs to be operated under a microscope, and the operation time is long, and the slight movement of the upper limb of the child will affect the operation, so the requirement of brachial plexus nerve block anesthesia is high. The highest point of axillary artery pulsation is taken in the conventional position, and a 20 ml syringe with a No. 7 needle is used to puncture the axillary sheath. If the older child can cooperate with the complaint of foreign sensation, it is more definite. Brachial plexus nerve block anesthesia, axillary method is safer, as long as the amount of local anesthetic is mastered, the injection process diligent back to draw, not into the blood is not easy to occur other complications, and the small volume of the axillary sheath of children, good diffusion, the block is more perfect, satisfactory anesthetic effect. 4, pay attention to intraoperative monitoring: close observation of respiratory changes, routine low-flow oxygen, monitoring heart rate, oxygen saturation, the child’s head in lateral position, ready to rescue intubation, suction, etc., to prevent respiratory depression, vomiting aspiration.
