During the past 10 years, the rapid development of ultrasound technology in clinical anesthesia has become one of the hot clinical researches. Researches in this area home and abroad also made great progress. On the one hand due to improved high-resolution portable ultrasound instrument and probe technology, ultrasound changed from a purely clinical diagnostic into the operating room; on the other hand, with the traditional method of anesthesia increasingly unable to meet the clinical requirements, it is an objective need of technological innovation for clinical anesthesia. And ultrasound has non-invasive, real-time, visible and repeatable characteristics which are able to provide accurate data and rich means for preoperative assessment, intraoperative monitoring and treatment of pain in pre-clinical anesthesia 展开更多
