Objective: To assess the influence of spinal anesthesia on bladder neck position and a clinical stress test in continent women.

Methods: In a prospective investigation, 14 women underwent urodynamic, sonographic and clinical assessment during spinal anesthesia. Results were compared to those obtained immediately preoperatively in the same patient.

Results: During spinal anesthesia, the bladder neck was found to be located significantly lower and more posterior, and in 4/7 parous patients (0/7 nullipara) the clinical stress test was positive.

Conclusion: These data provide additional evidence for the importance of neuromuscular function in the etiology of pelvic floor dysfunction and genuine stress incontinence.

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.

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.

Recurrent Urinary Tract Infections (UTIs): A Review and Proposal for Clinicians.

Antibiotics (Basel)

January 2025

Department of Anesthesia and Intensive Care Unit, ULSS6 Euganea, 35013 Cittadella, Padova, Italy.

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.

Background: The use of a fluid co-load has been shown to enhance hemodynamic stability and diminish the occurrence of hypotension after spinal anesthesia when paired with prophylactic norepinephrine. This research aimed to identify the effective dosages (ED and ED) of prophylactic norepinephrine boluses, in conjunction with a crystalloid co-load, for the prevention of hypotension after spinal anesthesia in cesarean delivery patients.

Methods: Patients were administered crystalloid co-loads at a dosage of 10 mL/kg, in addition to preventive norepinephrine dosages direct following spinal anesthesia administration.
