Effect of Nerve Block Under Ultrasound on Postoperative Prognosis in Children

Effect of Ultrasound-guided Rectus Abdominis Sheath Block on Analgesia and Agitation During the Awakening Period in Children After Single-port Laparoscopic Inguinal Hernia Repair

The goal of this study was to compare the incidence of pain and recovery agitation after single-port laparoscopic inguinal hernia repair in children. The main questions it aims to answer are:

• Reduction of postoperative pain by rectus sheath block compared with local anesthesia infiltration and control group
• A comparison between rectus sheath block and local anesthesia infiltration and control group on the reduction of agitation during postoperative recovery If there is a comparison group: The researchers will compare the ultrasound-guided rectus sheath group with the local anesthesia infiltration group and the control group to look at postoperative pain indicators and the incidence of waking agitation.

Postoperative emergence delirium is a common phenomenon in clinical practice, with an incidence rate of up to 20% to 80%. It has long been a concern and research topic in the medical community. In recent years, with the continuous improvement and updating of anesthesia technology, research on pediatric emergence delirium has become more and more in-depth.
