Use of hydroxocobalamin to treat intraoperative vasoplegic syndrome refractory to vasopressors and methylene blue during liver transplantation.

Introduction: For patients with catecholamine-resistant vasoplegic syndrome (VS) during liver transplantation (LT), treatment with methylene blue (MB) and/or hydroxocobalamin (B12) has been an acceptable therapy. However, data on the effectiveness of B12 is limited to case reports and case series.

Methods: We retrospectively reviewed records of patients undergoing LT from January 2016 through March 2022.

Safety and Feasibility of a Fast-Track Pathway for Neurosurgical Craniotomy Patients: Bypassing the Intensive Care Unit.

Objective: To describe the safety and feasibility of a fast-track pathway for neurosurgical craniotomy patients receiving care in a neurosciences progressive care unit (NPCU).

Patients And Methods: Traditionally, most craniotomy patients are admitted to the neurosciences intensive care unit (NSICU) for postoperative follow-up. Decreased availability of NSICU beds during the coronavirus disease-2019 delta surge led our team to establish a de-novo NPCU to preserve capacity for patients requiring high level of care and would bypass routine NSICU admissions.

Comparison of onset of neuromuscular blockade with electromyographic and acceleromyographic monitoring: a prospective clinical trial.

Background: Reliable devices that quantitatively monitor the level of neuromuscular blockade after neuromuscular blocking agents' administration are crucial. Electromyography and acceleromyography are two monitoring modalities commonly used in clinical practice. The primary outcome of this study is to compare the onset of neuromuscular blockade, defined as a Train-Of-Four Count (TOFC) equal to 0, as measured by an electromyography-based device (TetraGraph) and an acceleromyography-based device (TOFscan).

Bookshelf: A Biomedical Database of Books and Documents.

Bookshelf is a database maintained by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine that contains freely accessible online biomedical documents, including systematic reviews, technical reports, textbooks, and reference books. The database allows users to browse and search across all content and within individual books, and it is linked to other NCBI content. This article provides an overview of Bookshelf and demonstrates its usage in a sample search.

Perioperative Outcomes of Immersive Virtual Reality as Adjunct Anesthesia in Primary Total Hip and Knee Arthroplasty.

Background: Immersive virtual reality (IVR) is utilized as an adjunct to anesthesia to distract patients from their intraoperative environment, thereby potentially reducing sedative and narcotic medication usage. This study evaluated intraoperative and acute postoperative results of patients undergoing primary total hip (THA) and total knee arthroplasty (TKA) with and without IVR.

Methods: Utilizing IVR as an adjunct to spinal anesthesia, 18 primary THAs (n = 8) and TKAs (n = 10) were performed.

Transnasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) in type 1 thyroplasty.

Introduction: Transnasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) has been shown to benefit oxygenation, ventilation, and upper airway patency in laryngeal surgery. Its use in thyroplasty procedures has not been described. We hypothesized that the addition of THRIVE during type 1 thyroplasty procedures increases patient's safety and decreases the risk of an obstructive airway, while also decreasing the FiO with potential pooling of oxygen under the drapes.

Apneic Technique in Laryngotracheal Surgery.

Background Apneic oxygenation can be applied to select laryngotracheal procedures to improve operative visualization and avoid potential complications associated with intubation and jet ventilation.  Aims/objectives The authors sought to determine if apneic oxygenation using a high-flow nasal cannula could be used as a safe alternative airway management strategy for the duration of select laryngotracheal procedures. Methods Single institution, multi-site retrospective review of 38 adult (>18 years old) patients undergoing apneic oxygenation in the setting of various laryngotracheal procedures from January 2017 through January 2018.

Immersive Virtual Reality Used as Adjunct Anesthesia for Conversion Total Hip Arthroplasty in a 100-Year-Old Patient.

Immersive virtual reality (IVR) is an adjunctive form of anesthesia intended to distract patients from their intraoperative environment and reduce other side effects of sedating or narcotic agents. While this technology has been applied sparingly in various orthopedic procedural environments, its clinical utility has not been widely evaluated in major, nonelective surgical settings. The use of IVR in the geriatric hip fracture population represents a novel indication with potential benefit to reduced cognitive dysfunction and delirium.

Oxygen delivery failure due to improper installation of carbon dioxide absorbent canister: a case report.

The CLIC system in the Dräger Apollo anesthesia workstation allows a successful pre-use machine checkout without the presence of a carbon dioxide absorbent canister. It also allows the canister to be changed without interrupting controlled ventilation. However, this canister can be easily installed improperly with the CLIC adapter.

Oxygen therapy via a noninvasive helmet: A COVID-19 novelty with potential post-pandemic uses.

COVID-19 has placed a significant strain upon healthcare resources at a global level and refractory hypoxemia is the leading cause of death among COVID-19 patients. The management of limited resources such as mechanical ventilators has remained a contentious issue both at an individual and institutional level since the beginning of the pandemic. As a result, the COVID-19 pandemic has presented challenges to critical care practitioners to find innovative ways to provide supplemental oxygen therapy to their patients.

Bayesian predictive probabilities: a good way to monitor clinical trials.

Background: Bayesian methods, with the predictive probability (PredP), allow multiple interim analyses with interim posterior probability (PostP) computation, without the need to correct for multiple looks at the data. The objective of this paper was to illustrate the use of PredP by simulating a sequential analysis of a clinical trial.

Methods: We used data from the Laryngobloc trial that planned to include 480 patients to demonstrate the equivalence of success between a laryngoscopy performed with the Laryngobloc® device and a control device.

Emergency Airway Management During Awake Craniotomy: Comparison of 5 Techniques in a Cadaveric Model.

Background: During awake craniotomy, securing the patient's airway might be necessary electively or emergently. The objective of this study was to compare the feasibility of airway management using a laryngeal mask airway (LMA) and 4 alternative airway management techniques in an awake craniotomy simulation.

Methods: After completing a questionnaire, 9 anesthesia providers attempted airway management in a cadaver positioned to simulate awake craniotomy conditions.

A consensus checklist to help clinicians interpret clinical trial results analysed by Bayesian methods.

Introduction: In the context of an increasing number of publications of trial data analysed by Bayesian methods, clinicians need support to better understand Bayesian statistical methods. The existing checklists are intended for people who already know these methods. We aimed to establish and validate a checklist that contains a group of items considered crucial in interpreting the results of a phase III RCT analysed with Bayesian methods.
