Randomized Controlled Trial Comparative StudyPain After Unilateral Total Knee Arthroplasty: A Prospective Randomized Controlled Trial Examining the Analgesic Effectiveness of a Combined Adductor Canal Peripheral Nerve Block with Periarticular Infiltration Versus Adductor Canal Nerve Block Alone Versus Periarticular Infiltration Alone.
Total knee arthroplasty is a painful surgery that requires early mobilization for successful joint function. Multimodal analgesia, including spinal analgesia, nerve blocks, periarticular infiltration (PI), opioids, and coanalgesics, has been shown to effectively manage postoperative pain. Both adductor canal (AC) and PI have been shown to manage pain without significantly impairing motor function. However, it is unclear which technique is most effective. This 3-arm trial examined the effect of AC block with PI (AC + PI) versus AC block only (AC) versus PI only (PI). The primary outcome was pain on walking at postoperative day (POD) 1. ⋯ Participants who received AC + PI reported significantly less pain on walking on PODs 1 and 2 compared with those who received AC only or PI only.

ReviewThe Anesthesiologist's Role in Treating Abusive Head Trauma.
Abusive head trauma (AHT) is the most common cause of severe traumatic brain injury (TBI) in infants and the leading cause of child abuse-related deaths. For reasons that remain unclear, mortality rates after moderate AHT rival those of severe nonintentional TBI. The vulnerability of the developing brain to injury may be partially responsible for the poor outcomes observed after AHT. ⋯ The acute-on-chronic nature of the trauma along with synergistic injury mechanisms that include rapid rotation of the brain, diffuse axonal injury, blunt force trauma, and hypoxia-ischemia make AHT challenging to treat. The anesthesiologist must understand the complex injury mechanisms inherent to AHT, as well as the pediatric TBI treatment guidelines, to decrease the risk of persistent neurologic disability and death. In this review, we discuss the epidemiology of AHT, differences between AHT and nonintentional TBI, the severe pediatric TBI treatment guidelines in the context of AHT, anesthetic considerations, and ethical and legal reporting requirements.

Multicenter StudyThe Association Between Rheumatoid Arthritis and Adverse Postoperative Outcomes: A Retrospective Analysis.
Patients with rheumatoid arthritis have a high overall incidence of mortality, primarily because of cardiovascular complications. Thus, we tested the primary hypothesis that rheumatoid arthritis is independently associated with increased postoperative cardiovascular complications. Second, we determined whether rheumatoid arthritis is associated with increased thromboembolic complications, microcirculatory complications, and mortality. ⋯ Rheumatoid arthritis was not associated with an increased risk for postoperative cardiovascular complications.

Multicenter StudyObstetric Anesthesia Workforce Survey: A 30-Year Update.
Obstetric Anesthesia Workforce Surveys were conducted in 1981, 1992, and 2001, and the 10-year update was conducted in 2012. Anesthesia providers from US hospitals were surveyed to identify the methods used to provide obstetric anesthesia. Our primary hypothesis was that the provision of obstetric anesthesia services has changed in the past 10 years. ⋯ Since 2001, there have been significant changes in how responding hospitals provide obstetric anesthesia care and staff the labor and delivery ward. Obstetric anesthesia surveys, updated every 10 years, continue to provide information about changes in obstetric anesthesia practice.

Multicenter Study Observational StudyThe Use of Neuraxial Catheters for Postoperative Analgesia in Neonates: A Multicenter Safety Analysis from the Pediatric Regional Anesthesia Network.
Currently, there is limited evidence to support the safety of neuraxial catheters in neonates. Safety concerns have been cited as a major barrier to performing large randomized trials in this population. The main objective of this study is to examine the safety of neuraxial catheters in neonates across multiple institutions. Specifically, we sought to determine the incidence of overall and individual complications encountered when neuraxial catheters were used for postoperative analgesia in neonates. ⋯ Neuraxial catheter techniques for intraoperative and postoperative analgesia appear to be safe in neonates. Further studies to confirm our results and to establish the efficacy of these techniques across different surgical procedures are required. We suggest that each center that uses neuraxial anesthesia techniques in neonates closely evaluate the dose limits for local anesthetic agents and develop rigorous quality assurance methods to ensure potentially toxic doses are not used.
