Randomized Controlled TrialComparison of three obturator nerve block techniques for injectate spread into the obturator canal: a randomized controlled trial.
The obturator nerve branches into the obturator canal; therefore, local anesthetic spread into the obturator canal predicts the success of the obturator nerve block (ONB). We compared three ONB techniques for the spread of local anesthetic mixed with contrast medium into the obturator canal. ⋯ Local anesthetic spread into the obturator canal using the UMA was superior to that using the PA and IA. Both branches of the obturator nerve could be blocked using the UMA.

Randomized Controlled TrialComparison of iPACK and periarticular block with adductor block alone after total knee arthroplasty: a randomized clinical trial.
The infiltration between the popliteal artery and the capsule of the posterior knee (iPACK) has been described to provide analgesia without loss of muscle strength and is effective in functional recovery. This study compared iPACK + ACB (adductor canal block) with PAI (periarticular infiltration) + ACB and ACB alone in terms of postoperative analgesia and functional improvement. ⋯ The adding of an iPACK block to the ACB improves postoperative analgesia and reduces opioid consumption. In addition, this approach improves functional performance and reduces hospital stay.

Randomized Controlled TrialDifferential effects of remimazolam and propofol on heart rate variability during anesthesia induction.
The effects of remimazolam on autonomic nervous activity have not been elucidated. We investigated the differential effects of remimazolam and propofol on autonomic nervous activity during anesthesia induction. ⋯ Remimazolam and propofol decreased autonomic nervous activity during anesthesia induction. Remimazolam preserved the balance of sympathetic and parasympathetic activities, while propofol modulated it to sympathetic dominance.

Randomized Controlled TrialComparison of clinical effects of meperidine and sufentanil added to 0.5% hyperbaric bupivacaine for spinal anesthesia in patients undergoing cesarean delivery: a randomized controlled trial.
The objective of this study was to compare the effect of adding meperidine or sufentanil to hyperbaric bupivacaine in patients undergoing elective cesarean delivery (CD) under spinal anesthesia. The primary outcome was the first analgesic request time, and secondary outcomes included an analgesic requirement in the first 24 h and intraoperative and postoperative side effects. ⋯ ClinicalTrials.gov (NCT04446715).

Randomized Controlled TrialRemimazolam decreased the incidence of early postoperative nausea and vomiting compared to desflurane after laparoscopic gynecological surgery.
Postoperative nausea and vomiting (PONV) is a common adverse event after surgery. Remimazolam is a novel sedative agent recently approved for general anesthesia in Japan. This study evaluated the efficacy of remimazolam in the incidence of PONV after laparoscopic gynecological surgery under general anesthesia. ⋯ Remimazolam can reduce the incidence of PONV after laparoscopic gynecological surgery compared to general anesthesia with desflurane during the early postoperative period.
