Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07272954). This is a study registration, not published results. Lead sponsor: Affiliated Hospital of Jiaxing University. Recruitment status: NOT_YET_RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 136 participants (ESTIMATED). Conditions: Sleep Disorder (Disorder). Interventions: PROCEDURE: SGB; DEVICE: taVNS. Primary outcome measures: Total Sleep Time on the First Night Post-Surgery , the First Night Post-Surgery. Brief summary: This study aims to design a prospective, randomized, controlled, dual-center, non-inferiority trial to compare the effects of ultrasound-guided sympathetic ganglion block (SGB) and transcutaneous auricular vagus nerve stimulation (taVNS) on sleep quality following radical mastectomy for breast cancer. The objective is to explore whether non-invasive neuromodulation for sleep is non-inferior to invasive neuromodulation. Participants will be randomly assigned to receive either SGB or taVNS treatment. Sleep quality will be assessed using an actigraphy device and sleep scales within four days post-surgery, and the incidence of sleep disturbances will be followed up within 30 days post-surgery.
