Study Notes

Drawbacks and Limitations of Intravenous Fat Emulsion in Fertilization

Clinical manifestations of toxicities secondary to TCA overdose and ineffective metabolite of TCA are responsible for clinical problems, and lipid emulsion can neutralize only the effective metabolite of TCA.
Lipid emulsion can decrease the duration of physical findings of elevated vital organs, protecting life.
Serious or life-threatening adverse effects of IFE include hepatotoxicity, hypercoagulability, nausea, vomiting, facial swelling, pruritus, elevated factor VII plasma levels, disseminated intravascular coagulation, fat embolism syndrome, pulmonary embolism, anaphylaxis, hypotension, and acute pancreatitis.
Less severe adverse effects include electrolaryngy, distress syndrome in fetus, cyanosis, acrocyanosis, and discoloration.

Adverse Effects

Fat overload syndrome is rare, but factors like metabolic, pulmonary, cerebral, or thrombocytic-circulatory can increase its probability.
Intralipid is not previously studied in compromised kidneys, and its therapeutic use requires proper medication timing prior to surgery.
Intralipid shows no reliance on duration of action nor for INT operators.
Lipids are widely used in hospitals and chemistry.

Challenges in Implementation

Shipment of products prepared for emergency management should be centralized, including ready-to-use PREX MAT kits, drugs for reversal of neuromuscular blocking agents, ephedrine, vasopressin, IVFE, and IV fluids.
Standard NS infuse sets should have the longest NS injection angle to ensure undiluted product availability.
Nurses require practical knowledge of peripheral IV line dilution, including minimizing IV catheter flush volume and maximum administration rate.
Education modules or simulators can be implemented for IV medical administration.

IVFE Administration

Recommended dose of IVFE is 1.5 mL kg-1 as a single bolus, but it's unclear if other routes, doses, or patterns of administration could have similar or greater therapeutic success in treating LAST.
Time elapsed from the appearance of the first sign to the time of initiating IVFE administration is critical in obtaining a successful response.
IVFE has been administered 20 min after the onset of LAST symptoms in surgical patients with acceptable therapeutic success.
