Effect of preoperative oral rehydration before cesarean section on ultrasound assessment of gastric volume and intraoperative hemodynamic changes: a randomized controlled trial.

Background: Cesarean section often requires an urgent transfusion load due to decreased blood pressure after spinal anesthesia. This prospective randomized study aimed to investigate whether a preoperative oral rehydration solution (ORS) stabilized perioperative circulatory dynamics.

Methods: Sixty-three parturients scheduled for cesarean section under combined spinal epidural anesthesia (CSEA) were randomly allocated to one of three groups: Group O received 500 mL ORS before bedtime and 500 mL 2 h before CSEA; Group M received mineral water instead of ORS; and Group C had no fluid intake (controls).

Comparison of a new EMG module, AF-201P, with acceleromyography using the post-tetanic counts during rocuronium-induced deep neuromuscular block: a prospective, multicenter study.

Recent advances in neuromuscular monitors have facilitated the development of a new electromyographic module, AF-201P™. The purpose of this study was to investigate the relationship between post-tetanic counts (PTCs) assessed using the AF-201P™ and the acceleromyographic TOF Watch SX™ during rocuronium-induced deep neuromuscular block. Forty adult patients consented to participate in this study.

Ultrasound-guided internal jugular venipuncture using pocket-sized versus standard ultrasound devices: a prospective non-inferiority trial.

Purpose: Pocket-sized ultrasound devices (PUDs) are commonly adopted for bedside use despite their inferior performance compared with standard ultrasound devices (SUDs). We investigated the non-inferiority of PUDs versus SUDs for ultrasound-guided internal jugular venipuncture.

Methods: All patients undergoing scheduled surgery with general anesthesia and internal jugular vein catheter placement were prospectively included in this randomized non-inferiority trial to compare the qualities of the internal jugular venipuncture between the PUD group (Group P) and SUD group (Group S).

Use of intraoperative neuromuscular monitor reduces the reversal dose of sugammadex: a single-center retrospective study.

Purpose: We compared the reversal doses of sugammadex in surgical cases in which intraoperative neuromuscular monitor were used, to cases in which intraoperative neuromuscular monitoring was not used, retrospectively.

Methods: Data were collected by reviewing the electronic medical records of patients who received rocuronium and sugammadex during general anesthesia at Asahikawa Medical University Hospital between May 1, 2017 and April 30, 2018. The primary outcome was the reversal dose of sugammadex per patient actual body weight (mg/kg) between the group in which intraoperative neuromuscular monitoring was used (NM+ group) and the group in which intraoperative neuromuscular monitoring was not used (NM- group).

Effectiveness and Safety of Ultrasound Guided Lower Extremity Nerve Blockade in Infragenicular Bypass Grafting for High Risk Patients With Chronic Limb Threatening Ischaemia.

Objectives: Surgical revascularisation to accomplish limb salvage remains preferable in some patients with chronic limb threatening ischaemia (CLTI). The aim of this study was to evaluate the effectiveness and safety of ultrasound guided lower extremity nerve blockade (UGNB) in infragenicular bypass surgery (IGBS).

Methods: This was a single centre, retrospective clinical study.
