Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Total parenteral nutrition (TPN) is usually prescribed for patients recommended prolonged fasting after LT. The supplement of SMOFlipid (soybean oil, MCT oil, olive oil, and fish oil) has the advantage of being easily metabolised to produce energy, and it has anti-inflammatory effects. The major therapeutic mechanism of fish oil is the attenuation of systematic inflammation, which may decrease the mortality risk in patients with severe injury and sepsis. SMOFlipid has been proven to be safe and well tolerated in a wide range of clinical conditions, and it is used as the standard lipid emulsion. Moreover, the short-term application of parenteral fish oil with soybean oil not only significantly reduces the parameters of liver damage in the postoperative period but also leads to a more balanced immune response, which may result in the faster resolution of inflammation and recovery. However, SMOFlipid emulsion use may be associated with coagulopathy after LT. Early studies have shown that the dietary intake of n-3 fatty acids, which is a component of fat, is associated with antithrombotic effects but increases the risk of bleeding. A detailed analysis is lacking, and these observations have yet to be proven; this concern persists. Hence, the investigators should pay attention to the bleeding tendency when using fish oil fat emulsion because it may aggravate the risk of bleeding. Therefore, the use of fish oil-containing fat emulsion and its related risks is a clinically important issue in early LT that should be investigated, because liver function is not restored immediately after transplantation, and there is a tendency of coagulopathy. Thus, classical haemostasis parameters such as activated partial thromboplastin time (aPTT) and platelet count are measured prior to surgery and before the start of TPN. However, many questions remain unanswered regarding nutritional assessment and support for these seriously ill, nutritionally, and metabolically complex patients. This study evaluated the effect of the SMOFlipid supplement in TPN in LT patients.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
SMOFlipid group
TPN and SMOFlipid support were indicated for patients who received NPO for more than 3 days, such as those with repeated laparotomy, staged biliary reconstruction, massive nasogastric (NG) drainage (\>500 mL/day), ileus, diarrhoea, poor digestion (NG extraction \>50 mL/time), and chylous ascites.
Furthermore, SMOFlipid was discontinued when the platelet count decreased to 40,000/μL or less. In all cases, heparinisation was prescribed to maintain the aPTT level between 1.5 and 2 times the normal controlled level at least for 10-14 days, with daily blood examination conducted. Oral administration of dipyridamole (75 mg, QID) for 3 months was indicated for stimulation of antiplatelet activity when the platelet count increased to 40,000/μL or more.
SMOFlipid
non SMOFlipid group
On the basis of our experience in patient management at this institute, we allocated patients with a pretransplant platelet count less than 40,000/μL and those with a count more than 40,000/μL to the non-SMOFlipid group and the SMOFlipid group , respectively. Patients with well-tolerated oral intake and those in whom the TPN supplement was discontinued within 10 days were excluded from this study.
