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.
The objective of this study was to compare the hemodynamic effects of dobutamine and ephedrine during the management of anesthesia-related hypotension in healthy horses. Thirteen horses underwent general anesthesia with isoflurane and were randomly divided into two different groups, one of which received a dobutamine constant rate infusion (CRI) (1 µg/kg bwt/min) and the other received an ephedrine CRI (20 µg/kg bwt/min) when hypotension (<60 mmHg) was identified, following up to 15 min after the blood pressure reached 70 mmHg. All horses were equipped with a pulmonary artery catheter and a peripheral artery catheter, and multiparameter monitoring commenced as soon as they were under mechanical ventilation.

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.
