It is not a vibrator, it should be an analgesic pump, which is prepared by anesthesiologists near the end of the surgery, and inside it is mainly some pain-relieving drugs, which can be connected to the patient’s arm vein vessels, or connected to the catheter of epidural anesthesia, and it is mainly used to have an analgesic effect on the incision place after the surgery. If a patient has incision pain and abdominal pain after surgery, he or she will be less active, which is detrimental to the patient’s recovery. After the analgesic pump has worked, the patient’s abdominal pain is significantly reduced, so that the patient can get out of bed at an early stage, and can also promote the recovery of gastrointestinal function, so that the patient can eat at an early stage. Early getting out of bed activities can reduce the formation of lower extremity deep vein thrombosis, to prevent more serious complications such as pulmonary embolism.
