Objectives: To identify factors involved in reno-pulmonary interactions during mechanical ventilation.
Materials and methods: The study included a total of 25 domestic piglets. The animals were divided into three groups based on different strategies of ventilation. Group A; spontaneously breathing piglets; group B animals ventilated with tidal volume of 6 ml.kg–1 and group C with animals ventilated with tidal volume 10 ml.kg–1. Clinical monitoring and laboratory tests were performed for all groups at baseline and then at 1 hour and 12 hours for groups B and C. Ventilation indices, hemodynamics, urine output, creatinine clearance, glomerular filtration index, fractional excretion of sodium, free water clearance and tissue samples were recorded. The data obtained were statistically analysed.

Lower creatinine clearance and renal indices were seen in group B (p < 0.05) and in group C (p < 0.001) at 1 hour, and a difference in urine output for group C (p < 0.01) compared to group A was observed.

At 12 hours, there was a further reduction in creatinine clearance and renal indices for group B (p < 0.05) and group C (p < 0.01).

The lung mechanics and hemodynamics were not significantly influenced.
Conclusions: The study showed a causal relationship between renal dysfunction and positive pressure mechanical ventilation with respect to tidal volume and time (Tab. 4, Fig. 2, Ref. 17).

Keywords: renal, dysfunction, interactions, ventilation, tidal, volume.
