Effect of Nerve Block Under Ultrasound on Postoperative Prognosis in Children

Under ultrasound guidance, the probe was transversely placed at the lateral level of the umbilicus . Using the in-plane technique, the needle was advanced until the posterior aspect of the rectus muscle was penetrated. No blood and no gas were drawn back; furthermore, a small volume of saline was initially injected to ensure that the needle tip was correctly positioned. When the needle was located between the posterior rectus muscle and posterior sheath, 5ml of 0.25% ropivacaine was injected bilaterally

Local anesthesia drugs were injected into the peri-umbilicus cord
