Ethics approval and consent to participate
: This study protocol, the consent form, and related documents were reviewed and approved by the Yokohama City University Hospital institutional review board (reference number: B180405008). Informed consent will be obtained from all participants in this trial the day before surgery. Patients will be seen at least one day before the scheduled surgery to allow the patient some time to think about the trial. Patient autonomy and freedom will be respected and maintained. To ensure the quality of the explanation about the study and to answer any queries, only the research coordinator will initially meet with the patients. The consent form explains in detail the objective of the project, the risks, the advantages, and the time implications. The patients will be reminded that consent to participate in the trial will not affect the professionalism and the quality of care they receive. The patients will also be assured that they can withdraw consent at any time without being questioned. If consent is obtained, the recruiter will make sure the patient signs the consent form. If consent is not obtained, the patient will receive standard anesthesia (general anesthesia alone or in combination with FNB).
