Background: Advancements in veterinary medicine have expanded the potential of critical care;
however, prolonged immobilization may lead to substantial physical debilitation. While
early physiotherapy is crucial in human medicine for preventing and treating intensive
care unit-acquired weakness, its application in veterinary practice is less reported.
Materials and Methods: A 12-year-old Miniature Dachshund underwent pericardiectomy to relieve cardiac compression
caused by a heart base tumour and developed ARDS-like symptoms postoperatively, requiring
mechanical ventilation from postoperative days 2 to 5. Lymphatic drainage and PROM
exercises were administered to mitigate oedema and prevent joint contractures. After
weaning from the ventilator, oxygen therapy was needed due to reduced oxygenation.
Chest physiotherapy was employed to facilitate the expectoration of endotracheal secretions,
while exercise therapy was implemented to promote early mobilization ([Fig. 1]). Oxygenation was monitored via SpO2, and ventilation was assessed through PvCO2 and resting respiratory rate.
Results: Lymphatic drainage reduced oedema, improved vein visibility and eased venous catheterization.
Chest physiotherapy facilitated expectoration, improving SpO2 levels. Despite a gradual decrease in the oxygen concentration within the ICU, the
SpO2 levels remained elevated. Additionally, both the PvCO2 and the resting respiratory rate converged toward normal ranges ([Fig. 2]). The dog was initially unable to stand without assistance but was able to ambulate
independently at the time of discharge, 13 days postoperatively.
Conclusion: This case highlights the potential feasibility of early physiotherapy interventions
in critical care settings, including prevention of joint contractures, oedema reduction,
management of secretions, and exercise therapy during rest periods.
Fig. 1 The upper figure illustrates the changes in oxygen levels in the ICU and SpO2 values, while the lower figure depicts the changes in PvCO2 and resting respiratory rate. In this case, mechanical ventilation was administered
from postoperative days 2 to 5, and oxygen therapy was conducted from days 6 to 11.
