ReviewUnderstanding fascial anatomy and interfascial communication: implications in regional anesthesia.
With the extensive application of ultrasound in regional anesthesia, there has been rapid development of interfascial plane block techniques recently. Compared with neuraxial anesthesia or nerve plexus blocks, the interfascial plane blocks have many advantages, such as technical simplicity, fewer complications and comparable or better analgesia. The concept of fascial interconnectivity is fundamental in understanding the effects and complications of interfascial plane blocks. ⋯ This anatomical feature suggests that the space beneath the cervical prevertebral fascia, the thoracic paravertebral space, the space between transversalis fascia and psoas muscles (psoas major and quadratus lumborum), and the fascia iliaca compartment are a confluent potential cavity. Additionally, the permeability of the fascia at different anatomical locations to local anesthetics is different, which can also influence the block effect and the incidence of complications. This article summarizes the anatomical characteristics and communication relationships of the major fascia which are related to regional anesthesia, and their relationships with block effects and complications.

Review Case ReportsAn unusual foreign body in the oral cavity: a case report from a patient safety point of view and literature review.
Accidental foreign bodies (FBs) in the oral cavity, airway, esophagus and breathing circuit associated with anesthetic procedures are rare but can cause serious and life-threatening complications. We here present a case in which an unusual FB in the oral cavity was found after emergence from general anesthesia. ⋯ We then performed a review of the literature on FBs other than those of dental origin which were entrapped in the oral cavity, pharynx, larynx, trachea, esophagus, and anesthetic breathing circuit due to anesthetic procedures. From our case and 53 cases found in the search, we concluded that 1) use of disposable medical devices is recommended, 2) FBs can easily migrate into the oral cavity and airway during anesthesia, 3) delayed FB recognition may be associated with difficult intubation situations, and 4) more attention should be paid to the possibility of any medical or non-medical device becoming an FB during anesthesia.

Review Meta AnalysisInterpreting and assessing confidence in network meta-analysis results: an introduction for clinicians.
We aimed to provide clinicians with introductory guidance for interpreting and assessing confidence in on Network meta-analysis (NMA) results. ⋯ We recommend a careful approach to interpreting NMA results and the validity of an NMA depends on its underlying statistical assumptions and the quality of the evidence used in the NMA.

ReviewLess stress, better success: a scoping review on the effects of anxiety on anesthetic and analgesic consumption.
Preoperative anxiety has an incidence of 11-80% in patients undergoing surgical or interventional procedures. Understanding the role of preoperative anxiety on intraoperative anesthetic requirements and postoperative analgesic consumption would allow personalized anesthesia care. Over- or under-anesthetizing patients can lead to complications such as postoperative cognitive dysfunction in elderly patients, or procedural discomfort, respectively. ⋯ The analysis of the literature is limited by the heterogeneity of preoperative anxiety tools used, study designs, data analyses, and outcomes. The use of shorter, validated preoperative anxiety assessment tools may help optimize the intraoperative anesthetic and postoperative analgesic regimen. Further research to determine the most feasible and clinically relevant preoperative anxiety tool and subsequent implementation has the potential to optimize perioperative care and improve patient outcomes.
