Clinical Trial Summary

All patients who met the inclusion criteria were randomly divided into four groups, 30 cases in each group, which were lidocaine group 1, lidocaine group 1.5, lidocaine group 2, and the placebo group In lidocaine group 1, lidocaine group 1.5, and lidocaine group 2, 1% lidocaine 1.5 mg/kg was intravenously infused with a micropump after anesthesia induction, and the infusion was completed within 10 minutes according to the ideal body weight, and then continued for 1% lidocaine was infused at 1 mg/kg.h, 1.5 mg/kg.h and 2 mg/kg.h respectively until the end of the operation. In the placebo group, the same volume of normal saline was used instead.

All patients who met the inclusion criteria were randomly divided into four groups, 30 cases in each group, which were lidocaine group 1, lidocaine group 1.5, lidocaine group 2, and the placebo group In lidocaine group 1, lidocaine group 1.5, and lidocaine group 2, 1% lidocaine 1.5 mg/kg was intravenously infused with a micropump after anesthesia induction, and the infusion was completed within 10 minutes according to the ideal body weight, and then continued for 1% lidocaine was infused at 1 mg/kg.h, 1.5 mg/kg.h and 2 mg/kg.h respectively until the end of the operation. In the placebo group, the same volume of normal saline was used instead.Postoperative pain management during the first 72 postoperative hours will involve the use of a PCIA device, which will contain lidocaine 30mg/kg, sufentanil 2 μg/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline. In the placebo group, the same volume of normal saline will be administered during anesthesia. The postoperative PCIA device will contain sufentanil 2 μg/kg, granisetron 12 mg diluted to 200 mL in 0.9% normal saline solution with a total volume of 200 ml. All the background infusions of PCIA will set at 2 ml/h, the bolus volume of each PCIA press is 2 ml and the lockout interval is 15 min.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Immediate postoperative plasma lidocaine concentration	Plasma lidocaine concentration is an important indicator for evaluating the safety of the drug during use	Immediately after surgery
Secondary	Plasma lidocaine concentration immediately after loading	Plasma lidocaine concentration is an important indicator for evaluating the safety of the drug during use	30 minutes before surgery
Secondary	24-hour postoperative plasma lidocaine concentration	Plasma lidocaine concentration is an important indicator for evaluating the safety of the drug during use	24-hour postoperative
Secondary	The incidence of lidocaine toxicity within 72 hours after operation	Lidocaine toxicity mainly includes neurological manifestations such as dizziness, tinnitus, convulsions, cardiac manifestations such as bradycardia, new severe atrioventricular block and so on.	within 72 hours after operation
Secondary	The incidence of moderate to severe pain at 24?48 and 72 hours after surgery at rest and during movement;	he pain is evaluated using numerical rating scale(NRS). NRS scores range from 0 to 10 points, with 0 points representing no pain, 1-3 points representing mild pain, 4-6 points representing moderate pain, 7-9 points representing severe pain and 10 points representing the strongest pain.	24,48 and 72 hours after surgery
Secondary	The cumulative morphine consumption at 24, 48 and 72 hours postoperatively	intra-operative and postoperative opioid use is reported as morphine milligram	At the end of the surgery,24,48 and 72 hours after surgery
Secondary	Bowel function recovery	defined as the time to first defecation or time to first flatus	At 3 days after surgery
Secondary	Postoperative hospital stay	The days of hospital stay after the operation were calculated from the first day after the operation to the days of discharge.	up to 30 days
Secondary	Patient satisfaction scores	(satisfaction scores regarding pain control and the overall recovery process were obtained at 72 hours after surgery, using a 11-point Likert scale, with 0 indicating "very dissatisfied"and10 indicating "very satisfied"	72 hours after surgery
