Lack of Association Between Levels and Length of Intraoperative Controlled Hypotension and Acute Kidney Injury in Total Hip Arthroplasty Patients Receiving Neuraxial Anesthesia.
Previous research suggests that increased duration and lower levels of intraoperative hypotension (IOH) are associated with postoperative acute kidney injury (AKI). However, this association has not been evaluated in the context of intraoperative controlled hypotension (IOCH), a practice that has been linked in the past to improved outcomes with respect to blood loss and transfusion needs. This study aimed to investigate whether IOCH is associated with postoperative AKI among total hip arthroplasty patients at an institution where this technique is commonly practiced. ⋯ In this study, AKI was rare. We found a lack of association between IOH and postoperative AKI in a setting where neuraxial anesthesia-facilitated IOCH is routinely practiced. Therefore, it seems prudent for future research and clinical guidelines to consider the distinction between inadvertent and controlled hypotension.

Observational StudyAcute Pain Is Associated With Chronic Opioid Use After Total Knee Arthroplasty.
Pain scores are routinely reported in clinical practice, and we wanted to examine whether this routinely measured, patient-reported variable provides prognostic information, especially with regard to chronic opioid use, after taking preoperative and perioperative variables into account in a preoperative opioid user population. ⋯ Acute pain predicts chronic opioid use. Prospective studies of efforts to reduce acute pain, in terms of long-term effects, are needed.

A Novel Technique of Ultrasound-Guided Selective Mandibular Nerve Block With a Lateral Pterygoid Plate Approach: A Cadaveric Study.
We aimed to describe a novel technique of ultrasound-guided selective mandibular nerve block with a lateral pterygoid plate (LPP) approach and to assess its feasibility and accuracy in a soft cadaver model. ⋯ This study was registered at the Thai Clinical Trials Registry (ClinicalTrials.in.th), identifier TCTR20160601004.
