Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
arm1:intravenous (IV) lidocaine infusion:
IV lidocaine administration was performed 2 minute before orotracheal intubation.
Patients in arm1 received an IV bolus injection of lidocaine (1.5 mg/kg) followed by a continuous IV infusion at 2 mg/kg/hr during the operation (60 minutes).
arm2.intraperitoneal lidocaine instillation:
Intraperitoneal instillation of lidocaine (total instillation dose 3.5 mg/kg) were administered immediately after the creation of the pneumoperitoneum and 10 min before the beginning of surgery.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The details of the series are kept in a set of sealed envelopes, each bearing only the case number on the outside. After admitting into the operating room and just before the induction of anaesthesia, the numbered envelope was opened and the card inside determined which group the patient would be affiliated to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization into one of the three groups was based on Excel random-number generation.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Intra-peritoneal instillation of local anaesthetics in laparoscopic procedures reduces post-operative pain, analgesic requirements, the stress response and lengthens the period to first post-operative analgesic requirement.
Another alternative approach to accelerate outcomes after operation is intravenous lidocaine.
We hypothesized that intravenous lidocaine infusion and intraperitoneal lidocaine instillation reduce the pain after laparoscopic surgery. Therefore we investigated a comparative study on multimodal lidocaine pre emptive analgesia in laparoscopic appendectomy patients.
