Abstract
With the intensification of population aging, the improvement of visualization technology, and the concept of accelerated rehabilitation surgery, the anesthesia method of upper extremity surgery is gradually changing. However, these methods are often caused by anatomical variations and often have low block success rates and patient satisfaction. The neuroanatomical position should be accurately located so that the puncture needle is right next to the nerve bundle or in the nerve sheath. This is very important for implementing accurate brachial plexus anesthesia. This article uses ultrasound-guided positioning technology and traditional anatomical positioning technology for brachial plexus block treatment, aiming to explore the anesthesia effect of brachial plexus block with different techniques. This article selects 120 patients undergoing brachial plexus block surgery for forearm or hand surgery and divides these 120 patients into 6 groups with 20 people in each group. The first 3 groups were treated with brachial plexus block using ultrasound-guided positioning technology. The latter 3 groups were treated with brachial plexus block using traditional anatomical positioning technology. Experiments proved that during anesthesia, compared with the ultrasound group, the heart rate of the traditional anatomy group was significantly decreased (P < 0.05), and the average arterial pressure of the six groups of patients at each time point had no statistical difference (P > 0.05). This shows that whether it is ultrasound-guided positioning technology or traditional anatomical positioning technology, it has no effect on the average arterial pressure of the patient at each time point. In addition to intuitive and accurate viewing of needle and nerve contact, ultrasound real-time guidance allows intuitive viewing of anesthesia. This is a special advantage of nerve block under ultrasound guidance.
Highlights
In recent years, brachial plexus block has played an important role in clinic, especially in orthopedic shoulder, upper limb, and hand surgery
Test Subject. e objects of this experimental study are 120 patients who were hospitalized in X Hospital from January 18 to December 2020, and 120 patients with forearm or hand surgery under brachial plexus block, ASA I-II, male and female, age 18 to 60 years, weighing 49 to 83 kg. e 120 patients were divided into 6 groups with 20 people in each group. e first 3 groups were treated with brachial plexus block using ultrasound-guided positioning technology, and the latter 3 groups were treated with brachial plexus block using traditional anatomical positioning technology. e experiment was approved by the hospital ethics committee, and all patients understood and signed an informed consent form for anesthesia
The anesthesiologist needs to choose the approach of brachial plexus block and local anesthetics according to the conditions of the hospital, the patient’s surgical method and the familiarity with ultrasound, etc., and provide the patient with a good upper limb surgical anesthesia effect and postoperative analgesia effect
Summary
Brachial plexus block has played an important role in clinic, especially in orthopedic shoulder, upper limb, and hand surgery. Nerve stimulants and ultrasound positioning technology have been gradually introduced into clinical practice to make nerve block technology more advanced, and the application of network block anesthesia has become more and more common [1]. In traditional axillary brachial plexus block, the methods of locating anatomical landmarks and acupuncture to find abnormal feelings are often used. Axillary brachial plexus insufficiency is clinically more clinical. The radial nerve travels deep into the axillary artery due to nerve anatomy. Erefore, if the axillary brachial plexus nerve is blocked, the use of only local anesthetics will cause the upper extremity radial block to be incomplete, affecting The radial nerve travels deep into the axillary artery due to nerve anatomy. erefore, if the axillary brachial plexus nerve is blocked, the use of only local anesthetics will cause the upper extremity radial block to be incomplete, affecting
