This study is a comparative evaluation of the incidence of parenteral nutrition-associated liver disease (PNALD) when administering intravenous fat emulsions containing fish oil.
The medical records of patients who were in the neonatal intensive care unit at Severance Hospital from January, 2012 to December 2015, were reviewed retrospectively. Patients who were administered either soybean oil (SO) or SMOF (containing soybean oil, medium chain triglycerides, olive oil, and fish oil) more than 14 days were included. The patients were excluded if they were administered both agents or had underlying hepatic disease. An increase in bilirubin to 2 mg/dL was defined as PNALD.
PNALD occurred in only 8 out of a total of 77 patients: 6 out of 31 (19.4%) in the SO group and 2 out of 46 (4.3%) in the SMOF group (P=0.055). The number of patients, whose lab values, such as direct bilirubin, total bilirubin, asparate aminotransferase (AST), alanine amino-transferase, gamma-glutamyl transpeptidase, C-reactive protein, serum triglyceride, and alkaline phosphate, exceeded the normal range, were similar in both groups. The gestational age, birth body weight, and APGAR score at 1 min and 5 min were significantly higher in the SO group and the PN duration was significantly long in the SMOF group. Considering only term infants, there were no significant differences in baseline characteristics and incidence of PNALD. The number of patients whose AST exceeded the normal range was significantly higher in the SO group (P=0.034).
The incidence of PNALD was similar in both groups. On the other hand, considering the tendency, there was a high correlation between the type of lipid emulsion and an increased direct bilirubin level in the SO group.
This study performed a comparative evaluation of nutritional condition’s improvement and clinical effects in accordance with the Nutrition Support Team (NST) consultation compliance of critically ill pediatric patients.
The medical records of 64 critically ill pediatric patients (2 to 18 years old), who were officially referred to a NST consultant in pediatric intensive care unit from January to August 2015, were reviewed. The patients were divided into 2 groups according to the compliance of NST consultation answers. The total delivered/required caloric and protein ratio, weight, serum total protein, serum albumin, hemoglobin, and hematocrit were compared.
According to the NST consultation answer, ‘nutrition support increase’ occupied the largest proportion at 38.5%; ‘maintenance’ and ‘decrease’ accounted for 35.7% and 18.2% respectively. The NST compliance group and non-compliance group were 20 and 14 patients, respectively. Although total delivered/required caloric ratio was significantly increased in the NST compliance group (19.7%, P=0.036), there was no significant difference in the NST non-compliance group (5.1%, P=0.692). The total delivered/required protein ratio was increased (15.1%, P=0.163) in the NST compliance group and decreased (?4.7%, P=0.774) in the NST non-compliance group. The NST non-compliance group (?8.6%, P=0.219) was further reduced weight than the NST compliance group (?1.0%, P=0.820). The serum albumin was significantly increased in the NST compliance group (13.1%, P=0.003), but there was no difference in the NST non-compliance group (7.1%, P=0.433).
Although 56.7% of NST consultations were needed for nutritional interventions, a lower NST compliance (53.8%) is the limit of nutritional support. The NST compliance group was supplied adequately with more calories and protein than before consultation and a more improved nutritional status. Therefore, aggressive NST consultation can help increase the therapeutic effect by improving the nutritional status. This study will form the basis to seek ways to further enhance NST compliance.
