this randomized controlled trial selects patients undergoing gynecological laparoscopy under general anesthesia. By using noise reduction earphones during surgery, the patient's postoperative pain score and demand for opioids are observed, providing a basis and reference for the efficacy and safety of noise reduction earphones in gynecological endoscopic surgery.
Every year, 200 million surgical procedures are performed worldwide, and 40-65% of patients experience moderate to severe pain after surgery Failure to provide sufficient postoperative analgesia increases the risk of surgical complications and affects patients' early activity and recovery . Opioids are still the main method of treatment, and their side effects include urinary retention, itching, nausea, vomiting, postoperative intestinal obstruction, dizziness and cognitive impairment . Researchers pay more and more attention to non pharmacology and non-invasive analgesia methods, including music therapy, traditional Chinese medicine acupuncture and moxibustion and watching educational videos . Due to the introduction of various surgical tools, the noise pollution in the operating room has gradually intensified, affecting surgical patients and medical staff. Previous studies have shown that general anesthesia does not hinder the brain's processing ability for sound and language; The patient's auditory cortex remains active , and even in anesthesia induced coma, the patient can still maintain the ability to understand auditory information. Other recent studies have found that intraoperative exposure to positive auditory stimuli, including music, treatment suggestions and white noise, can reduce postoperative pain, environmental protection, and acupuncture and moxibustion can also have a similar positive impact . Therefore, this randomized controlled trial selects patients undergoing gynecological laparoscopy under general anesthesia. By using noise reduction earphones during surgery, the patient's postoperative pain score and demand for opioids are observed, providing a basis and reference for the efficacy and safety of noise reduction earphones in gynecological endoscopic surgery.

Standard monitoring techniques include electrocardiogram, pulse oximeter, heart rate and blood pressure monitoring, continuous monitoring of bispecific index of electroencephalography, and the use of remifentanil (0.3 mg/kg) Rapid sequence induction was performed using sufentanil (0.3 μ g/kg), propofol (2.5mg/kg), and rocuronium bromide (0.6 mg/kg). Anesthesia was maintained using remifentanil (0.1-0.2 μ g/0kg/min), inhaled sevoflurane (1%), and intravenous propofol (1-4 mg/kg/h) to maintain BIS 40-60, with heart rate and blood pressure within 20% of baseline values. |
