Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
60 ASA physical status II–III patients who underwent hepatectomy surgery for resection the hepatic neoplasms who had history of hepatitis B related cirrhosis under combined general and epidural anesthesia were enrolled after signed an approved informed consent.
Sequentially-Numbered, Opaque, Sealed Envelopes (SNOSE) were used as allocation concealment method.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was based on computer-generated codes that were maintained in opaque envelopes until the anesthesia began
Masking / blinding
Open (masking not used)
