OBJECTIVE: To study the clinical effect of multi-oil fat emulsion for parenteral nutrition support in extremely low birth weight (ELBW) infants. METHODS: A retrospective analysis was performed for 49 ELBW infants who were admitted from January 1, 2018 to July 30, 2020, with an age of ≤14 days on admission and a duration of parenteral nutrition of > 14 days. According to the type of lipid emulsion received, the ELBW infants were divided into two groups: soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) ( RESULTS: The 49 ELBW infants had a mean birth weight of (892±83) g and a mean gestational age of (28.2±2.3) weeks. There was no significant difference between the two groups in the incidence rates of hemodynamically significant patent ductus arteriosus, intraventricular hemorrhage, neonatal necrotizing enterocolitis, retinopathy of prematurity, bronchopulmonary dysplasia (BPD), grade Ⅲ BPD, sepsis, and pneumonia ( CONCLUSIONS The application of multi-oil fat emulsion in ELBW infants does not reduce the incidence rate of complications, but compared with MCT/LCT emulsion, SMOF can reduce the severity of PNAC in ELBW infants.

Herbal products have been used for therapeutic purposes for a long time. However, many herbs can be toxic and even life-threatening. If refractory ventricular tachycardia (VT) is caused by herbal products and shows no response to conventional therapy, intravenous lipid emulsion (ILE) therapy can be considered. We report a case of herbal intoxication leading to refractory VT, which was successfully treated with ILE therapy. A 36-year-old woman with aplastic anemia presented with mental changes. She had taken an unknown herbal decoction three days before visiting the hospital. Soon after coming to the hospital, she went into cardiac arrest. Cardiopulmonary resuscitation was performed, and return of spontaneous circulation with VT was achieved. Synchronized cardioversion was then performed and amiodarone was administered. However, VT with pulse continued, so ILE therapy was attempted, which led to the resolution of VT.

Aluminum (Al) is the third most abundant element in the earth's crust and is omnipresent in our environment, including our food. However, with normal renal function, oral and enteral ingestion of substances contaminated with Al, such as antacids and infant formulae, do not cause problems. The intestine, skin, and respiratory tract are barriers to Al entry into the blood. However, contamination of fluids given parenterally, such as parenteral nutrition solutions, or hemodialysis, peritoneal dialysis or even oral Al-containing substances to patients with impaired renal function could result in accumulation in bone, parathyroids, liver, spleen, and kidney. The toxic effects of Al to the skeleton include fractures accompanying a painful osteomalacia, hypoparathyroidism, microcytic anemia, cholestatic hepatotoxicity, and suppression of the renal enzyme 25-hydroxyvitamin D-1 alpha hydroxylase. The sources of Al include contamination of calcium and phosphate salts, albumin and heparin. Contamination occurs either from inability to remove the naturally accumulating Al or from leeching from glass columns used in compound purification processes. Awareness of this long-standing problem should allow physicians to choose pharmaceutical products with lower quantities of Al listed on the label as long as this practice is mandated by specific national drug regulatory agencies.

At an intensive care unit, four neonates died consecutively within 80 minutes. Citrobacter freundii was isolated from blood samples of the 4 patients. It was also cultured from the leftover SMOFlipid that had been infused intravenously into the patients. In this in vitro study, we evaluated the bacterial growth kinetics and change in size of fat globules in SMOFlipid contaminated with C. freundii. Following the growth of bacteria, pH of SMOFlipid decreased to < 6, and the number of fat globules larger than 5 µm increased. Pulmonary fat embolism is proposed as a possible cause of the sudden deaths as well as fulminant sepsis.

OBJECTIVETo investigate the fat emulsion tolerance in preterm infants of different gestational ages in the early stage after birth.

METHODSA total of 98 preterm infants were enrolled and divided into extremely preterm infant group (n=17), early preterm infant group (n=48), and moderate-to-late preterm infant group (n=33). According to the dose of fat emulsion, they were further divided into low- and high-dose subgroups. The umbilical cord blood and dried blood filter papers within 3 days after birth were collected. Tandem mass spectrometry was used to measure the content of short-, medium-, and long-chain acylcarnitines.

RESULTSThe extremely preterm infant and early preterm infant groups had a significantly lower content of long-chain acylcarnitines in the umbilical cord blood and dried blood filter papers within 3 days after birth than the moderate-to-late preterm infant group (P<0.05), and the content was positively correlated with gestational age (P<0.01). On the second day after birth, the low-dose fat emulsion subgroup had a significantly higher content of short-, medium-, and long-chain acylcarnitines than the high-dose fat emulsion subgroup among the extremely preterm infants (P<0.05). In the early preterm infant and moderate-to-late preterm infant groups, there were no significant differences in the content of short-, medium-, and long-chain acylcarnitines between the low- and high-dose fat emulsion subgroups within 3 days after birth.

CONCLUSIONSCompared with moderate-to-late preterm infants, extremely preterm infants and early preterm infants have a lower capacity to metabolize long-chain fatty acids within 3 days after birth. Early preterm infants and moderate-to-late preterm infants may tolerate high-dose fat emulsion in the early stage after birth, but extremely preterm infants may have an insufficient capacity to metabolize high-dose fat emulsion.

PURPOSE: This study is a comparative evaluation of the incidence of parenteral nutrition-associated liver disease (PNALD) when administering intravenous fat emulsions containing fish oil. METHODS: 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. RESULTS: 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). CONCLUSION: 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.

Aconitum is a genus of various species of flowering plants that belongs to the Family Ranunculaceae. Most Aconitum sp. have extremely toxic alkaloid substances such as aconitine, mesaconitine and hypaconitine. Among these substances, aconitine can cause fatal cardiotoxicity by activating sodium channels followed by calcium channels in myocardial cells. Even though there have been various therapeutic plans suggested comprising antidotes based on diverse case reports and studies, there is no confirmatory treatment protocol for aconite poisoning. Here, we report an aconite poisoning patient who had refractory ventricular tachyarrhythmia that did not respond to intravenous amiodarone therapies even though they were sustained for over 2 hours, but showed successful recovery following intravenous fat emulsions (IFE) therapy.

OBJECTIVETo investigate the effect of parenteral nutrition support with a lipid emulsion formulation (containing soybean oil, medium chain triglycerides, olive oil, and fish oil [SMOF]) in intensive care patients following major gastrointestinal surgeries.

METHODSAccording to a randomized, prospective and case-controlled design, 72 intensive care patients following major gastrointestinal surgeries between January and December, 2014 were randomized equally into SMOF group and control group to receive parenteral nutrition support with SMOF and medium or long chain lipid emulsion, respectively. Before and at 4 and 9 days after commencement of parenteral nutrition support, the patients were examined for alanine aminotransferase (ALT), total bilirubin (TBIL), albumin (propagated), C-reactive protein (CRP), interleukin 6 (IL-6), and endotoxin levels. The patients' average length of stay in intensive care unit (ICU), the days of using antibiotics, and the incidence rate of postoperative complication were recorded.

RESULTSOn day 4 postoperatively, the levels of CRP and IL-6 were significantly lower in SMOF group than in the control group (t=2.669 and 2.676, respectively; P<0.05), and on day 9, the patients in SMOF group showed significantly lower levels of ALT, TBIL, CRP and IL-6 (t=2.487, 3.497, 3.762, 2.180, respectively; P<0.05) than the control group, but ALB and endotoxin levels remained comparable between the two groups. The average length of stay in ICU and the days of using antibiotics were significantly shorter in SMOF group than in the control group (t=2.94 and 2.17, respectively; P<0.05); SMOF group showed a lower incidence of postoperative infections than the control group, but the difference was not statistically significant (χ² =1.047, P>0.05).

CONCLUSIONFor intensive care patients following major gastrointestinal surgeries, postoperative parenteral nutrition support with SMOF can effectively reduce the release of inflammatory mediators, protect important visceral functions, reduce postoperative complications, shorten the length of ICU stay, and improve the prognosis of the patients.

PURPOSE: The purpose of this study was to evaluate the usefulness of intravenous lipid emulsion as well as adverse events in acute poisoning patients. METHODS: Literature was accessed through PubMed, EMBASE, Cochrane library, Web of science, and KoreaMed. All forms of literatures relevant to human use of intravenous lipid emulsion for acute poisoning were included. Cases reports or letters without description of clinical outcomes for each case were excluded. The literature search was conducted by two investigators in March, 2015, with publication language restricted to English and Korean. The effect, onset time, and adverse event of lipid emulsion and final outcome of each case were analyzed. RESULTS: Eighty-one published articles were included, excluding articles whose title and abstract were not relevant to this study. No articles were classified as high level of evidence. Sixty-eight case reports were identified, consisting of 25 local anesthetics and 43 other drugs, such as tricyclic antidepressants and calcium channel blockers. Although most cases described significant clinical improvements, some of them showed no beneficial effect or worsening of clinical course. Several adverse events including hyperamylasemia and laboratory interference were reported. CONCLUSION: Although there were many case reports illustrating successful use of lipid for various drug poisonings, the effect cannot be estimated due to significant possibility of publication bias. Therefore, lipids might be considered in severe hemodynamic instability resulting from lipophilic drug poisoning, however further studies should follow to establish the use of lipid as the standard of care.
