Bone marrow puncture will definitely be anesthetized, and the bone marrow puncture operation will be a little painful. Many people are punctured with thicker needles. Adults do bone marrow puncture only with local anesthesia, played by the operating doctor, mainly blocking the skin and blocking the periosteum, and these two parts are played with local anesthesia, which can reduce the pain to a degree that the patient can tolerate when doing bone marrow puncture. If a child has a blood disorder, the most important test for blood disorders is bone marrow aspiration, if the child is not in pain after playing local anesthesia, but there is still some discomfort or slight pain, the child is not able to cooperate, that is, this kind of children want to do bone marrow aspiration, then will choose a way similar to general anesthesia, may be through intramuscular injection or intravenous drugs, local anesthesia will still play, which can greatly reduce the magnitude of pain This can greatly reduce the amount of pain and, together with other anesthetic drugs, make it safer for the child to complete the bone marrow puncture with cooperation. Some mothers may be a little concerned when they hear that general anesthesia is required for this small operation. For the protection of the child, because the child’s movement during the operation may cause the operation to be incomplete and the bone marrow sampling may be problematic, so to ensure the child’s cooperation, local anesthesia may not be sufficient and general anesthesia will be used. In adults, local anesthesia is usually sufficient for bone marrow aspiration, and there may be some mild pain and discomfort.
