Abstract:
BACKGROUND: Peripheral parenteral nutrition (PPN) is increasingly considered as an alternative to central parenteral nutrition (CPN) given the higher cost and more frequent clinical complications associated with the latter. However, the assessment of potential risks and benefits of PPN in critically ill pediatric canine patients has not been extensively performed. In this study, we aimed to explore the effect of short-term, hypocaloric PPN on weight loss, length of hospital stay, the incidence of complications, adverse effects, and mortality in critically ill pediatric canine patients. RESULTS: Between August 2015 and August 2018, a total of 59 critically ill pediatric canine patients aged from 1 to 6 months admitted at the Veterinary Sciences Research Institute of the Autonomous University of Baja California were included in this non-randomized clinical trial. Canine pediatric patients were initially allocated to 3 groups: 11 in group 1 receiving parenteral nutrition (PN) supplementation equivalent to 40% of the resting energy requirement (RER), 12 in group 2 receiving supplementation of 50% of the RER, and 36 in group 3 receiving no PN supplementation. After establishing that there was no significant difference between 40 and 50% of PN supplementation, these groups were not separated for downstream analysis. Similar lengths of hospital stays were noted among study subjects who received PN supplementation and those who did not (4.3 ± 1.5 vs. 5.0 ± 1.5, days, p = 0.097). No metabolic-, sepsis- or phlebitis-related complications were observed in any animal in the PPN supplemented group. Higher mortality (19.4% vs. 0%, p = 0.036), and a greater percentage of weight loss (9.24% vs. 0%, p < 0.001) were observed in patients who received no supplementation. CONCLUSION: Even though short-term, hypocaloric PPN did not reduce the length of hospital stay, it was associated with lower mortality and resulted in mitigation of weight loss. In contrast to previous studies evaluating central and peripheral parenteral nutrition protocols, we observed a lower frequency of metabolic, septic, and phlebitis complications using a 40-50% parenteral nutrition treatment. The parenteral nutrition therapeutic intervention used in our study may reduce PN-related adverse effects and promote a favorable disease outcome in critically ill canine patients. Larger studies will be needed to confirm these observations.
