Article Synopsis
- - Pulmonary atelectasis is a common issue during anesthesia, and mechanical ventilation along with alveolar recruitment maneuvers (ARMs) and positive end-expiratory pressure (PEEP) can help improve lung function, despite the risk of lung injuries like volutrauma and barotrauma.
- - The study aimed to assess how lung volume distribution changes with different levels of PEEP during ARMs in 12 anesthetized dogs, using CT scans for detailed monitoring.
- - Results showed that ARMs significantly improved lung ventilation and static compliance, especially at specific PEEP levels (10 and 5 cmHO), while also affecting cardiovascular measures like heart rate and mean arterial blood pressure.
Background: Electrical impedance tomography (EIT) has been an essential tool for assessing pulmonary ventilation in several situations, such as the alveolar recruitment maneuver (ARM) in PEEP titration to maintain the lungs open after atelectasis reversion. In the same way as in humans and dogs, in horses, this tool has been widely used to assess pulmonary aeration undergoing anesthesia, mechanical ventilation, recruitment maneuver, standing horses, or specific procedures.
Objectives: The present study aimed to evaluate the distribution of regional ventilation during ARM based on lung monitoring assessment by EIT, with a focus on better recruitment associated with less or no overdistention.
Objective: To evaluate gas exchange, respiratory mechanics, and hemodynamic impact of mechanical ventilation with low tidal volume (V) in dogs with the use of positive end-expiratory pressure (PEEP) or preceded by alveolar recruitment maneuver (ARM).
Study Design: Prospective randomized clinical trial.
Animals: Twenty-one healthy client-owned mesocephalic healthy dogs, 1-7 years old, weighing 10-20 kg, and body condition scores 4-6/9 admitted for periodontal treatment.
Background: During protective mechanical ventilation, electrical impedance tomography (EIT) is used to monitor alveolar recruitment maneuvers as well as the distribution of regional ventilation. This technique can infer atelectasis and lung overdistention during mechanical ventilation in anesthetized patients or in the ICU. Changes in lung tissue stretching are evaluated by monitoring the electrical impedance of lung tissue with each respiratory cycle.

Domestic healthy dogs received dental scaling and polishing under general anesthesia. Under standard feeding and homecare during 7 days, 20 dogs were randomly placed into 2 different groups for dental treatment.

Objectives: We aimed to evaluate hematologic, biochemical, and blood gas variable alterations that occur in canine pRBCs during storage, and their effects on recipient clinicopathologic parameters.
Methods: The study was conducted in two phases.
