Observational StudyRelationship between changes in regional cerebral blood volume and oxygenation and changes in cardiac output and systemic vascular resistance during spinal anesthesia in women undergoing cesarean section.
The decrease in maternal regional cerebral blood volume (rCBV) and oxygenation (rCBO) during spinal anesthesia for cesarean section depends on the severity of hypotension. We examined the relationships between changes in the systemic circulatory parameters, cardiac output (CO) and systemic vascular resistance (SVR), and rCBV and rCBO after induction of spinal anesthesia, evaluated by near-infrared spectroscopy (NIRS) and an arterial pressure-based cardiac output monitoring system (APCOs). ⋯ The decreases in both rCBV and rCBO after induction of spinal anesthesia for cesarean section are probably dependent on the decrease in SVR due to spinal anesthesia.

Randomized Controlled Trial Comparative StudyRocuronium Bromide Intravenous Solution Maruishi® is more suitable than ESLAX Intravenous® during rapid-sequence induction of anesthesia.
Rocuronium Bromide Intravenous Solution® (Maruishi Pharmaceutical Co., Ltd, Osaka, Japan) is a newly developed generic drug and we have noticed that compared with conventional rocuronium formulations [e.g. Esmeron (Eslax), MSD Co. Ltd., Tokyo, Japan], rocuronium Maruishi appeared to cause less pain or withdrawal movement. The aim of this study was to assess the hypothesis that the injection of rocuronium Maruishi causes less body movement than rocuronium MSD does, during rapid-sequence induction of anesthesia. ⋯ Compared with rocuronium MSD, rocuronium Maruishi is more suitable than conventional rocuronium formulations, for rapid-sequence induction of anesthesia.

Randomized Controlled Trial Comparative StudyUse of a curved needle to facilitate lateral sagittal infraclavicular block performance: a randomized clinical trial.
Failed needle-tip positioning in an ultrasound-guided infraclavicular block can be due to improper needle insertion point and steep needle insertion angle. Needle pre-curving enables the user to pass the needle with different curved trajectories on approaching the brachial plexus. Aim of the study was to compare curved and non-curved needles as regards the time needed to perform the lateral sagittal infra-clavicular block. ⋯ The use of a curved needle reduces the time required to perform the lateral sagittal infraclavicular block. The curved needle provides less procedure pain and higher satisfaction levels among anesthetists than the non-curved needle.

Randomized Controlled Trial Comparative StudyEffects of the nontourniquet combined with controlled hypotension technique on pain and long-term prognosis in elderly patients after total knee arthroplasty: a randomized controlled study.
The aim of this study was to confirm the alleviating effects of the nontourniquet technique on the postoperative acute and chronic pain of patients after total knee arthroplasty (TKA). ⋯ The nontourniquet combined with controlled hypotension technique can alleviate chronic pain and promote the long-term rehabilitation of patients after TKA.
