Abstract

OBJECTIVE: To determine the impact of mechanical ventilation (MV) and perfusion conditions on the efficacy of pulse-delivered inhaled nitric oxide (PiNO) in anesthetized horses. ANIMALS: 27 healthy adult horses. PROCEDURES: Anesthetized horses were allocated into 4 groups: spontaneous breathing...

Abstract

The arterial to end-tidal CO2 difference (P(a-ET)CO2) and alveolar dead space fraction (VDalvfrac=P(a-ET)CO2/PaCO2), are used to estimate Enghoff's "pulmonary dead space" (V/QEng), a factor which is also influenced by venous admixture and other pulmonary perfusion abnormalities and thus is not just ...

Abstract

Objectives: To investigate the influence of two inspired oxygen fractions (Fi'O2) on the arterial oxygenation in horses anaesthetized with isoflurane. Study Design: Retrospective, case-control clinical study. Animals: Two hundred equine patients undergoing non-abdominal surgery (ASA class 1-2),...

Abstract

Objective: To discuss how hypoxaemia might be harmful and why horses are particularly predisposed to developing it, to review the strategies that are used to manage hypoxaemia in anaesthetized horses, and to describe how successful these strategies are and the adverse effects associated with them....

Abstract

Background: The purpose of this study was to compare the effects of 0.5 fraction of inspired oxygen (FiO2) and >0.95 FiO2 on pulmonary gas exchange, shunt fraction and oxygen delivery (DO2) in dorsally recumbent horses during inhalant anesthesia. The use of 0.5 FiO2 has the potential to reduce...

Abstract

Impairment of gas exchange and arterial oxygenation during general anaesthesia and recumbency of the horse are a common and well-known problem. Often these alterations are poorly responsive to intermittent positive pressure ventilation (IPPV) and increasing levels of supplemental oxygen. Over the...

Abstract

A horse with acute colic underwent exploratory laparotomy. Following anaesthetic induction, the inspired fraction of oxygen (FiO2) was found to be 0.23 and severe hypoxaemia (PaO2: 4.12 kPa [30.9 mmHg]) was detected. The terminal oxygen outlet was delivering mostly pressurised room air due to a...

Abstract

Horses are susceptible to developing large areas of pulmonary atelectasis during recumbency and anesthesia. The subsequent pulmonary shunt is responsible for significant impairment of oxygenation. Since ventilation perfusion mismatch persists into the post-operative period, hypoxemia remains an...

Abstract

Objectives: Anaesthetized horses commonly become hypoxaemic due to ventilation/perfusion (Vdot over˜A/Qdot over˜) mismatch and increased pulmonary shunt fraction (Qdot over˜s/Qdot over˜t). Pulse-delivered inhaled nitric oxide may improve oxygenation but may increase plasma concentration of the...

Abstract

The equine patient suffering from acute abdomen syndrome anesthesia remains one of the biggest challenges for the veterinary anesthesiologist. Despite many advances on mechanical ventilation, volemic status monitoring and critical care patient management it is still extremely difficult to achieve...
