PURPOSE OF REVIEW: Tumescent anaesthesia is a method of administering dilute local anaesthetic into the subcutaneous tissue. Many anaesthesiologists are unfamiliar with the technique, its applications and potential risks. RECENT FINDINGS: The maximum safe dose of lidocaine with epinephrine in tumescent anaesthesia for liposuction is probably between 35 and 55 mg/kg. Without liposuction, the maximum dose of lidocaine with epinephrine should be no more than 28 mg/kg...

Combinational nanomedicine is becoming a topic of much interest in cancer therapy, although its translation into the clinic remains extremely challenging. One of the main obstacles lies in the difficulty to efficiently co-deliver immiscible hydrophilic/hydrophobic drugs into tumor sites. The aim of this study was to develop co-loaded lipid emulsions (LEs) to co-deliver immiscible hydrophilic/hydrophobic drugs to improve cancer therapy and to explore the co-delivery abilities between co-loaded LEs and mixture formulation...

Breast cancer is among the most important causes of cancer related death in women. There is a need for novel agents for targeting key signaling pathways to either improve the efficacy of the current therapy, or reduce toxicity. There is some evidence that curcumin may have antitumor activity in breast cancer. Several clinical trials have investigated its activity in patients with breast cancer, including a recent trial in breast cancer patients receiving radiotherapy, in whom it was shown that curcumin reduced the severity of radiation dermatitis, although it is associated with low bioavailability...

REVIEW

This review discusses the use of intravenous lipid emulsion (ILE) in the treatment of intoxications with lipophilic agents in veterinary medicine. Despite growing scientific evidence that ILE has merit in the treatment of certain poisonings, there is still uncertainty on the optimal composition of the lipid emulsion, the dosing, the mechanism of action, and the efficacy. Therefore, a critical view of the clinician on the applicability of this modality in intoxications is still warranted. The use of ILE therapy is advocated as an antidote in cases of intoxications with some lipophilic substances...

Objective Omega-3 fatty acids are vital for brain and retinal maturation. It is not clear if early use of ω-3 fatty acids in the form of fish-oil lipid emulsions (FLEs) prevents retinopathy of prematurity (ROP) in preterm infants. The aim of this meta-analysis is to evaluate whether early administration of parenteral FLEs reduces ROP requiring laser therapy or severe ROP ≥stage 3 in preterm infants. Methods A literature search was performed to identify studies comparing parenteral FLEs with soybean-based lipid emulsions (SLEs) in preventing ROP...

The incidence of toxic effects of drugs leading to emergency department visits has increased in the United States in the past several years. Most of these patients can be adequately managed by supportive care alone. However, pharmacological antidotes may be necessary, particularly in patients with hemodynamic instability. In severe cases refractory to conventional antidote therapy, rescue therapy with intravenous lipid emulsion (ILE) may be necessary. Traditionally, ILE has been used as an antidote of choice in treating toxic effects of local anesthetics...

OBJECTIVES: Intravenous lipid emulsion (ILE) has been used increasingly over the last decade for a range of drug overdoses. Although the use of ILE in local anesthetic toxicity (LAST) is well established, the hemodynamic effectiveness of ILE in non-LAST poisonings is still unclear. Thus, the primary objective of this study was to examine a cohort of poisoned patients in whom ILE was administered. METHODS: Consecutive patients were identified by calls to a regional poison center from May 1, 2012 to May 30, 2014...

Intoxications may lead to life-threatening emergencies. While stabilising the patient, therapy should focus on a rapid and effective elimination of the toxin. General measures for decontamination (gastrointestinal, dermal, ocular) aim to effectively decrease the absorption of the poisonous substance. Further classification of the substance and its properties can assist with the choice of specific treatment options, including dialysis and specific antidotal therapy. In recent years, treatment with lipid emulsions for enhanced elimination of lipophilic substances has become an important therapeutic option...

Intravenous fat emulsion (IVFE) is an important source of calories and essential fatty acids for patients receiving parenteral nutrition (PN). Administered as an individual infusion or combined with PN, the fats provided by IVFE are vital for cellular structural function and metabolism. The affinity of some medications to lipids has led to the use of IVFE as a treatment for any lipophilic drug overdose. This article will explain the available formulations of IVFE, administration, and maintenance issues, as well as the risks and benefits for various applications...
