Failure of spinal anaesthesia for caesarean section may have deleterious consequences for the mother as well as the newborn baby. In this article, we discuss the mechanisms of failure of spinal anaesthesia as well as the approach to a failed block. We performed a literature search in Google Scholar, PubMed, and Cochrane databases for original and review articles concerning failed spinal anaesthesia and caesarean section. Strategies for a failed spinal anaesthetic include manoeuvers to salvage the block, repeating the block, epidural anaesthesia or a combined spinal-epidural (CSE) technique, or resorting to general anaesthesia. Factors influencing the choice of these alternative options are discussed. A "failed spinal algorithm" can guide the anaesthesiologist and help reduce morbidity and mortality.

Pericapsular nerve group cryoneurolysis as an option for palliative nonoperative management of hip fracture in a patient with end-stage medical comorbidities.

Department of Anesthesiology, Perioperative and Pain Medicine, Alberta Health Services and Cumming School of Medicine, University of Calgary, South Health Campus, 4448 Front St. SE, Calgary, AB, T3M 1M4, Canada.
Purpose: We report the use of a pericapsular nerve group (PENG) cryoneurolysis for longer-term analgesia in a patient with a hip fracture and severe medical comorbidities as an alternative to hip fracture surgery.
Clinical Features: A frail but lucid and fully autonomous 97-yr-old female from an assisted living facility sustained a subcapital fracture of her right proximal femur following a ground level fall. She had significant comorbidities including end-stage respiratory disease.
An Overview of Adult Acute Traumatic Neurologic Injury for the Anesthesiologist: .
Curr Anesthesiol Rep
January 2025
Department of Anesthesiology and Pain Medicine, Harborview Medical Center, University of Washington, Seattle, WA, USA.
Purpose Of Review: We examine what is known, what is new, and what is emerging in acute neurotrauma relevant to the anesthesiologist.
Recent Findings: Timely and goal-directed care is critical for all patients requiring urgent/emergent anesthesia care. Anesthesia care for acute neurological injury should incorporate understanding the evolution of traumatic brain injury and spinal cord injury that translates to preoperative preparation, hemodynamic resuscitation, prevention of second insults, and safe transport between care settings.
Current research and guidelines for euthanasia in laboratory fish with a focus on fathead minnows.
Lab Anim
January 2025
Environment and Climate Change Canada, Burlington, Canada.
This paper reviews the methods and approaches used to humanely anesthetize (render unconscious) and or euthanize (kill) laboratory fish (in research settings), with a specific focus on the fathead minnow. We surveyed the literature (333 scientific studies published 2004-2021) to examine euthanasia methods used for various life stages. Our findings showed that many published scientific papers do not provide an adequate description of anesthesia or euthanasia methods, particularly for larval fathead minnows.

Neurofibromatosis is a genetic disorder arising de novo or with an autosomal dominant transmission that typically presents either at birth or in early childhood, manifesting through distinctive clinical features such as multiple café-au-lait spots, benign tumors in the skin, bone enlargement, and deformities. This literature review aims to resume the spectrum of maternal and fetal complications encountered in pregnant women with neurofibromatosis type 1 (NF1). Thorough research was conducted on databases such as Web of Science, PubMed, Science Direct, Google Scholar, and Wiley Online Library.

The pathogenesis of recurrent urinary tract infections (rUTIs), a common problem in the female population, is becoming better understood following recent studies of bacterial persistence and intracellular bacterial communities. Incorporating these new insights, we propose pulsed antibiotic therapy with intracellular activity as a possible treatment for rUTIs.
