Effect of Noise Blocking During General Anesthesia on Postoperative Pain

Effect of Noise Blocking During General Anesthesia on Postoperative Pain in Patients Undergoing Laparoscopic Abdominal Surgery

To investigate the effect of noise blocking during general anesthesia on postoperative pain in patients undergoing laparoscopic abdominal surgery. The aim of this study was to determine whether noise blocking can reduce postoperative pain, analgesic use, and its possible effects on intraoperative electrocorticogram.

Inclusion Criteria:

• ASA Classification ⅰ-ⅲ
• Patients undergoing elective laparoscopic abdominal surgery under general anesthesia
• Voluntarily accept PCIA and signed informed consent

Exclusion Criteria:

• Patients with previous severe disease
• Patients with hearing abnormalities
• Patients requiring mechanical ventilation or undergoing epidural catheters or other types of regional anesthesia after surgery
• Patients with chronic preoperative pain and/or long-term analgesic use
