Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients who meet the enrollment criteria will be randomized 1:1 to the lidocaine group or placebo group.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients who meet the enrollment criteria will be randomized 1:1 to the lidocaine group or placebo group. In the lidocaine groups, lidocaine 1.5mg/kg/h was continuously infused (using ideal body weight) during the whole procedure, postoperative analgesia pump with lidocaine (lidocaine 50mg/kg, sufentanil 2ug/kg, glassetron 12mg), diluted to 200ml with saline until 72h after surgery. Blood samples will be collected from some patients in the lidocaine group for the measurement of lidocaine plasma concentration.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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients were randomized in a 1:1 lidocaine group, placebo control group using a computer-generated random number table. After the randomization scheme is written, use the opaque envelope, hide each group envelope into an opaque envelope, the envelope outside the code, is sealed to the researcher, when the study, if the inclusion criteria, then open the corresponding numbered envelope, and intervene according to the group scheme in the envelope.
Primary Study Purpose

PREVENTION

Blinding Strategy

DOUBLE

Participants Outcome Assessors
Blinding of research personnel and patients will be maintained throughout the observation period. On the day of surgery, nurses who did not participate in the perioperative management will assign the standard configuration of the trial drugs, including intraoperative medication and the configuration of the postoperative analgesic pump, to the researchers before the induction of anesthesia. Throughout the study, the patients and researchers should not be unblinded until the statistical analysis of the study data is completed.

During the operation, an independent anesthesiologist will be responsible for the blood draw, and the postoperative blood samples will be collected together with the routine blood examination specimens. The investigators remained blinded throughout the observation period until the anesthesiologist or assessors observe significant adverse events of local general anesthesia toxicity.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Lidocaine group

Patients in the lidocaine groups, lidocaine 1.5mg/kg/h was continuously infused (using ideal body weight) during the whole procedure, postoperative analgesia pump with lidocaine (lidocaine 50mg/kg, sufentanil 2ug/kg, glassetron 12mg), diluted to 200ml with saline until 72h after surgery. Blood samples will be collected from some patients in the lidocaine group for the measurement of lidocaine plasma concentration.
