Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Enrollment is decided and permission of the patient is obtained by two of the anesthesiologists during preoperative rounding,.This is a double blinded clinical trial, with blinding of both the patient and the administrating practitioner to the anaesthetic type. Allocation will be managed by a Resident external to the project. The blinding will occur through use of equal amounts of pretreatment drugs (2ml’s) Each syringe will be labeled A ,B,C,D orE according to its contents.
. The drug syringes are handed over to anesthesiologists blinded to the patient allocation to carry out the induction of anesthesia
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was based on computer-generated codes
Masking / blinding
Blinded (masking used)
