Abstract

Background: Mannitol has been proven effective in treating cerebral oedema, owing to its osmotic diuretic effect. However, its potential to transiently increase plasma volume raises uncertainties about its impact on dogs with mitral avalve insufficiency.

Objectives: This study aimed to investigate the effects of mannitol on haemodynamics and cardiac load in dogs with experimentally induced mitral regurgitation (MR), with a particular focus on the potential adverse effects of high doses of mannitol.

Methods: We used implantable telemetry to monitor MR dogs for 12 consecutive hours, recording and comparing the dynamic changes in their mean left atrial pressure (mLAP) and heart rate at different doses of mannitol (low [0.5 g/kg], medium [1 g/kg] and high [2 g/kg]).

Results: Compared with that in the control group, the low- and medium-dose groups demonstrated a proclivity towards increased mLAP after administration, but without statistical significance. The high-dose group exhibited an immediate increase in the mLAP after administration (p < 0.001), followed by a gradual return to baseline 1 h later.

Conclusions: This study provides crucial reference data for the use of mannitol in treating MR. It is particularly important to exercise caution when administering high doses of mannitol to dogs with advanced stages of MR.

期刊介绍： Veterinary Medicine and Science is the peer-reviewed journal for rapid dissemination of research in all areas of veterinary medicine and science. The journal aims to serve the research community by providing a vehicle for authors wishing to publish interesting and high quality work in both fundamental and clinical veterinary medicine and science. Veterinary Medicine and Science publishes original research articles, systematic reviews, meta-analyses, and research methods papers, along with invited editorials and commentaries. Original research papers must report well-conducted research with conclusions supported by the data presented in the paper. We aim to be a truly global forum for high-quality research in veterinary medicine and science, and believe that the best research should be published and made widely accessible as quickly as possible. Veterinary Medicine and Science publishes papers submitted directly to the journal and those referred from a select group of prestigious journals published by Wiley-Blackwell. Veterinary Medicine and Science is a Wiley Open Access journal, one of a new series of peer-reviewed titles publishing quality research with speed and efficiency.
