简要总结
To evaluate the efficacy and safety of different doses of triamcinolone for local infiltration analgesia during total knee replacement
详细描述
Participants were enrolled according to protocol requirements. Patients who meet all inclusion criteria and do not have any exclusion criteria will be considered for inclusion in the study and will provide the relevant information used orally and in writing. Patients were divided into four groups according to the dose of triamcinolone in the peripheral infiltrating anesthetic preparation. All of which are appropriate for their surgical treatment, and the purpose of the study is to determine which formula is clinically better. All patients enrolled in this study were voluntary participants and signed informed consent. On the day of the surgery, the anesthesiologist prepares a mixture of medications based on patient groups, which are then handed to the operating room nurse. The timing, dose, and site of injection were consistent. Before the prosthesis is installed, the mixture is injected into the upper part of the patella, the posterior joint capsule, and the patellar tendon. After the prosthesis was installed, the mixture was injected into the lateral joint capsule and subcutaneous tissue. The patient, the rehabilitation physician, and the ward nurse did not know the type of mixed drug preparation injected by the patient.

盲法说明
An independent researcher, who would not meet or interact with patients before recruiting them, compiled a computer-generated randomised list using 1:1 assignments and random blocks of 8, 6 or 4 to ensure the invisibility of assignments. The groups corresponding to the numbers generated by the random number generator were placed in opaque envelopes and sealed, and the enrolled patients were assigned envelopes in the chronological order in which they were enrolled. On the day of surgery, the anesthesiologist prepares to mix the drug preparation after opening the sealed envelope, which is then handed to the operating room nurse. The patient, the rehabilitation physician, and the ward nurse did not know the type of drug mixture the patient was injected with.
