Research progress on sacral plexus anatomy and ultrasound-guided block technique
Intercostal nerve block is a commonly used technique for anesthesia and pain management during thoracic and ab-dominal surgery.In recent years,ultrasound guidance has become increasingly used in clinical settings due to its unique advantages of safety,real-time and dynamic detection,and visualization,which promotes the development of intercostal nerve block.At present,the application of ultrasound-guided intercostal nerve block and anterior cutaneous branch of the block emerges in clinical practice.This article mainly reviews the current research on ultrasound-guided intercostal nerve block at home and aboard,the anatomical basis of in-tercostal nerves,the clinical application range of ultrasound-guided intercostal nerve block,the dosages of local anesthetics,complica-tions and contraindications,and specific surgical techniques for each different approach.These findings will provide reference for clini-cal anesthesia and pain diagnosis and treatment.
