Author Abstract

Background: Squeezing the reservoir bag on the anaesthetic breathing system to inflate the lungs (colloquially known as bagging) is a technique commonly used during general anaesthesia in veterinary practice. Despite being straightforward to perform, the physiological implications are important to understand. Furthermore, catastrophic consequences can occur and staff must be vigilant and trained correctly when using this technique to manage ventilation during anaesthesia.

Aim of the article: This article provides an overview of the indications and contraindications of manual bagging, and reviews relevant literature from human medicine.

Duration of efficacy and effect of implant location in adult queens treated with a 9.4 mg deslorelin subcutaneous implant.
The average duration of action of the 9.4 mg deslorelin implant was 790 ± 155 days (range 525-1140 days) with no significant difference in duration or efficacy depending on implantation sites. The 9.4 mg deslorelin implant causes pharmacological sterilization for about 2 years in female cats, is fully reversible, and caused no clinically relevant side effects when administered at both interscapular and periumbilical sites.

Choose Your Own Adventure: Using Twine for Gamified Interactive Learning in Veterinary Anaesthesia.
Five interactive clinical cases were developed using Twine, simulating realistic anaesthesia scenarios with decision points and gamified elements, such as scoring systems and resource management. Feedback was highly positive; 90.8% found it effective for training, and 97.0% agreed it improved knowledge. User-friendliness was rated as "easy" or "very easy" by 94.6%. Regarding overall satisfaction, 96.7% of students described the workshop as "good" or "excellent".

Case Series: Computed Tomography Features of Extraskeletal Osteosarcoma in Six Dogs.
Although the presence of intralesional mineralization is not a pathognomonic finding, it was consistently identified in the present case series. Therefore, exOSA should be considered in the differential diagnosis when mineralization occurs in a mass unrelated to osseous structures.

Resolution of egg binding is possible in most client-owned parrots when multiple treatment strategies are considered.
Of the 150 events that had complete follow-up, 109 (72.7%) resulted in a successful outcome. A successful outcome was observed in 44 of 133 events (33.1%) that were initially managed medically without resorting to additional treatment strategies, in 31 events (86.1%) managed with mechanical assistance, in 20 events (60.6%) managed surgically, and in 12 events (85.7%) managed with ovocentesis.

Retrospective cohort study on diseases and risk factors associated with death in hospitalized neonatal foals.
Most prevalent diseases were sepsis (43.9%), enteritis (14.0%), and omphalitis (9.0%). Case fatality rate was 33.3%. Neonatal sepsis significantly increased the risk of death.
