10 minutes before the infusion saline 1.5mg/kg was administered to the patient. Subsequnetly, a continuous intravenous infusion saline 2mg/kg/h was maintained until the end of the sugery. Before closing the abdominal cavity, 20ml normal saline was administered.
10 minutes before the infusion 2% lidocaine 1.5mg/kg was administered to the patient. Subsequnetly, a continuous intravenous infusion 2% lidocaine 2mg/kg/h was maintained until the end of the sugery. Before closing the abdominal cavity, 20ml normal saline was administered.
10 minutes before the infusion saline 1.5mg/kg was administered to the patient. Subsequnetly, a continuous intravenous infusion saline ( 2mg/kg/h) was maintained until the end of the sugery. Before closing the abdominal cavity, 2% lidocaine (4-5mg/kg) + 1/200,000 epinephrine was spraged into the abdominal cavity.

RECRUITINGThe incidence rate of moderate to severe pain within 24 hours
Pain severity was measured using The NRS((Numerical Rating Scale),The NRS≥4 was considered moderate to severe pain. If the NRS score is greater than or equal to 4 at least once within 24 hours, it is considered moderate to severe pain.
Time frame: Within 24 hours after surgery
NRS scores at different time intervals
The severity of pain was measured using the NRS(Numerical Rating Scale), with NRS≥4 indicating moderate to severe pain. The NRS scores for movement, rest, and wound pain at 2 hours, 4 hours, 8 hours, 12 hours, and 24 hours after surgery were observed to determine whether intraperitoneal spray combined with intravenous lidocaine could reduce the incidence of moderate to severe pain in patients undergoing laparoscopic myomectomy.
Time frame: 2 hours, 4 hours, 8 hours, 12 hours, 24 hours after surgery
Sleep quality
The subjective sleep status of Day 0, Day 1 and Day 2 was assessed using the AIS scale. For patients with an AIS score of 4 or higher, the Insomnia Severity Index (ISI) was used to classify the degree of insomnia.
Time frame: Within 48h hours after surgery
Recovery quality
The Qor-15 scale was used to evaluate the recovery quality of patients in the first two days. QoR-15 Assessment Questionnaire:It includes five dimensions:physical comfort(5 items),physical independence(2 items),emotional state(4 items),psychological support(2 items),and pain(2 items). Scoring details: Each item is scored on an 11-point scale.Higher scores for positive items indicate higher frequency. The total score ranges from 0(worst recovery)to 150(best recovery).
Time frame: The first two days after surgery
The consumption of analgesic drugs.
The consumption of analgesic drugs was recorded, defined as the cumulative consumption of opioids during surgery and the number and type of rescue medications used after surgery.

10 minutes before the infusion 2% lidocaine (1.5mg/kg) was administered to the patient. Subsequnetly, a continuous intravenous infusion 2% lidocaine ( 2mg/kg/h) was maintained until the end of the sugery. Before closing the abdominal cavity, 2% lidocaine (4-5mg/kg) + 1/200,000 epinephrine was spraged into the abdominal cavity.
Time frame: Within 24 hours after surgery
The number of lidocaine adverse reactions, postoperative nausea and vomiting, and the use of vasoactive drugs.
The number of adverse reactions to lidocaine in patients during and within 24 hours after surgery was recorded, including tinnitus, perioral numbness, nystagmus, impaired consciousness, muscle twitching, convulsions, coma, bradycardia, arrhythmia, conduction block, hypotension, and circulatory collapse. The number and dosage of vasoactive drugs used by patients during surgery were recorded. The number of postoperative nausea and vomiting occurrences was recorded, defined as the recording of any nausea or vomiting within 24 hours after surgery.
Time frame: During surgery and within 24 hours after surgery
BIS value
The BIS values of patients before surgery, before skin incision, 30 minutes into the surgery, and at the end of the surgery were recorded.
Time frame: During the operation
The time for recovery of bowel function
Record the recovery time of gastrointestinal function,which is defined as the time of the patient's first flatus,first defecation,and removal of the urinary catheter immediately after the surgery.
Time frame: After surgery
