Background
The pain degree of abdominal operation is closely related to the operation mode, operation range, operation type and the like, and the postoperative pain mainly originates from abdominal incision. Thus, blocking pain conduction from this source can greatly reduce postoperative pain. The transverse fascia is a part of the intra-abdominal fascia, and is a part of the intra-abdominal fascia lining the inner surface of the anterior-lateral wall of the abdomen. The transverse fascia is most developed in the inguinal region and forms the abdominal ring and other structures. The ultrasonic-guided lower abdominal transverse fascia blocking technology can reduce the floating of blood pressure and heart rate in abdominal operation, relieve postoperative pain, shorten postoperative time for getting out of bed and exhaust time, and reduce the application of the combined anesthesia dosage for lumbar and hard and postoperative analgesic drugs, and based on the ultrasonic-guided lower abdominal transverse fascia blocking technology, the use of abdominal transverse fascia blocking in postoperative analgesia of the abdomen is more and more common and practical.
The ultrasonic abdominal transverse fascia arrest operation often requires one person to fix the ultrasonic probe with his left hand, insert the needle with his right hand, fix the needle body, and then push the drug from another person. When only one person needs to finish the steps independently, the right-hand puncture needle is required to be loosened and replaced by right-hand medicine pushing, in the process, because no special force is needed to hold the puncture needle, the puncture needle is easy to generate angle deflection when the breathing degree of a patient is large, a light person can cause local anesthetic to not correctly reach an anesthetic cavity, the anesthetic effect is weakened, a serious person can puncture the viscera of the patient, and the viscera bleeding can be caused.
