Symptoms And Signs

ABSTRACT Cataract surgery is performed routinely under regional orbital blocks including retrobulbar and peribulbar blocks. Several complications have been reported while performing these blocks, the most significant of which is the local anesthetic systemic toxicity (LAST). The symptoms and signs present in a varied spectrum, but every such case requires early recognition and immediate resuscitation to avoid long-term morbidity and even death. Lipid emulsion therapy forms the mainstay of treatment. We present a case of a 49-year-old man who planned to undergo cataract surgery under the peribulbar block, who developed LAST and was successfully treated with 20% lipid emulsion without any adverse sequelae.

Local Anesthetic Systemic Toxicity

Local anesthetics are used with neuraxial and regional techniques to provide pain relief, most commonly postoperatively. Each agent is a sodium-channel blocker, although each agent differs in onset of action, potency, duration of action, and safety profile. Chemical structure and lipophilicity are the main determinants of these characteristics. The agents may be used alone or in combination with an additive which alters the local anesthetic’s properties . Clinically, local anesthetics provide pain relief in a multimodal approach. This reduces opiate consumption, opiate-related adverse effects, and length of stay. Additional benefits when using neuraxial techniques include decreases in mortality, venous thromboembolism, myocardial infarction, pneumonia, respiratory depression, and duration of ileus. Although there are many adverse effects, the most serious include neurologic and cardiovascular. Seizures and cardiac arrest may result from local anesthetic systemic toxicity when systemic levels are elevated or the patient is predisposed. Dose adjustment, removal, or reversal of the agent may be clinically indicated. Lipid emulsion therapy is a reversal agent which acts as a sequestering vehicle for the local anesthetic. Liposomal bupivacaine, the newest formulation of local anesthetic, may provide an increased duration of action compared with standard formulations, although more evidence is needed. This review contains 5 figures, 5 tables, and 59 references.

Delays In Diagnosis

Local anesthetic systemic toxicity is a major concern in both the inpatient and the outpatient setting, especially with the current increased use of regional, local, and tumescent anesthesia. Lack of protective strategies, delays in diagnosis, and the inability to provide timely lipid emulsion treatment are among the leading preventable causes to contribute to patients’ harm.

Local Anesthetic Systemic Toxicity

Abstract Background: The paper presents a case report of an episode of local anesthetic systemic toxicity (LAST) with cardiac arrest after continuous femoral nerve blockade in a 74-year-old female patient after elective total knee replacement surgery. Case presentation: A 74-year-old patient burdened with hypertension, osteoarthritis, underwent elective total knee replacement surgery (TKR). After surgery, a continuous femoral nerve blockade was performed and an infusion of a local anesthetics (LA) was started using an elastomeric pump. Five hours after surgery, the patient had an episode of generalized seizures followed by cardiac arrest. After resuscitation, spontaneous circulation was restored and the patient was transferred to the Intensive Care Unit. 20% lipid emulsion was used in the treatment. On day 2 of the ICU stay, the patient was fully cardiovascularly and respiratorily stable without neurological deficits and was discharged to the orthopedic department to continue treatment. Conclusion: Systemic toxicity of LA is a serious and potentially fatal complication of the use of LA in clinical practice. The incidence of LAST is underestimated, although in recent years there has been a significant decrease in the incidence of this serious complication. It should be noted that in nearly 40% of patients, LAST deviates from the classic and typical course and may have an atypical manifestation, and the first symptoms may appear with a long delay, especially when continuous blockades are used. Therefore, proper supervision of the patient and the developed procedure in the event of LAST is undoubtedly important here. If the first serious symptoms of LAST appear, current guidelines recommend early application of 20% lipid emulsion.

Local Anesthetic Systemic Toxicity

Abstract Introduction: Local Anesthetic Systemic Toxicity (LAST) is the most feared local anesthesia accident. As the cardiac arrest determined by LAST is mostly refractory to known resuscitation protocols, due local anesthetic blockade produced in the cardiac cells, the Lipid Emulsion (L.E) has been proved to be beneficial in resuscitating the cardiac arrest determined by local anesthetic. The aim for this presentation is to ease future studies on this topic, to ensure a starting point for next related research on LAST and LE mechanism of action. Method: Under genaral anesthesia we induced Local Anesthetic Systemic Toxicity to a rat model, by injecting Ropivacaine into the inferior vena cava. We monitored the cardiac activity of the subjects during the experiment. We used 4 groups of rats, control group- no intervention, lipid group- lipid emulsion was adminsitered, local anesthetic group- local anesthetic was administered and local anesthetic and lipid emulsion group- a dose of lipid emulsion was adminsitered before administering the local anesthetic. Results: After a few attemps to incannulate teh peripheral veins we tried the more complex approach of inferior vena cava, which ensured a secure access which allowed us to repetedly adminster the local anesthetic and the lipid emulsion. Conclusion: The presented experimental animal model of induced LAST and the protective effects of LE is one of the few described in the literature, is a reproducible model, feasible, simple, low cost and can be used as starting point in future LAST research.
