Randomized Controlled Trial Retracted PublicationEffects of ultrasound-guided stellate-ganglion block on sleep and regional cerebral oxygen saturation in patients undergoing breast cancer surgery: a randomized, controlled, double-blinded trial.
Numerous factors could contribute to sleep disturbances in women with breast cancer. We hypothesized that stellate ganglion block (SGB) during surgery would preserve sleep after surgery and increase intraoperative regional cerebral oxygen saturation (rSO2) on the blocked side in patients undergoing breast cancer surgery. A randomized, double-blinded, controlled trial was conducted at the First Hospital of China Medical University from January 2016 to September 2016. ⋯ No differences in rSO2 were observed on either the left or right side of the patients in either group 50 min after anaesthesia induction. We conclude that ropivacaine-SGB combined with general anaesthesia might increase the first postoperative sleep duration without influencing the intraoperative rSO2 in female patients undergoing elective breast cancer surgery.
