It is primarily used for local pain control in minor procedures, as an antiarrhythmic for cardiac arrhythmia, and as ointments and gels for topical anesthesia. The active ingredient blocks voltage-gated sodium channels in cell membranes, inhibiting the conduction of nerve impulses. This property makes lidocaine an effective pain reliever, but overdose or improper use poses significant risks for small animals.\n\nLidocaine toxicity differs significantly between animal species. Cats are particularly sensitive due to their limited capacity for glucuronidation\u2014an important metabolic pathway for breaking down medications in the liver. While dogs have somewhat higher tolerance, even small overdoses can cause severe signs of poisoning in them as well. The therapeutic window\u2014the gap between an effective and a toxic dose\u2014is relatively narrow in both species.","wirkungsmechanismus":"Lidocaine increases the excitation threshold in nerve cells and slows impulse conduction.\nIn the heart muscle, lidocaine reduces excitability, the speed of impulse conduction and contractile force, thereby lowering the risk of arrhythmia.\n\nLidocaine poisoning in pets mainly arises from three scenarios: iatrogenic overdose during veterinary treatment, accidental oral ingestion of lidocaine-containing products, or improper use by pet owners.\n\nIn iatrogenic poisoning, excessively high doses, overly rapid intravenous administration, or unintended intravascular injection during what was meant to be subcutaneous use can lead to toxic plasma levels. Animals with impaired liver or kidney function are particularly at risk, as metabolism and excretion of the active ingredient may be delayed.\n\nAccidental oral ingestion usually occurs when animals gain access to the owner\u2019s medications. Although orally ingested lidocaine is subject to a significant first-pass effect in the liver, toxic plasma levels can still occur if larger amounts are ingested. In cats, this effect is even more pronounced due to their metabolic characteristics.\n\nAnother common cause is improper use by pet owners who apply human lidocaine products to their pets. The concentration of these products is often unsuitable for animals, and the dose is frequently calculated incorrectly. Combination products are particularly dangerous because, in addition to lidocaine, they may contain other active ingredients that can be toxic to animals.","toxisches_prinzip":"Lidocaine is absorbed after oral ingestion. It is also dangerous because cats have limited ability to break it down.\nThe toxic effects of lidocaine initially affect the central nervous system (CNS).

Conclusion<\/h3>\n<p data-start=\"4789\" data-end=\"5465\">Lidocaine poisoning in dogs and cats results from systemic overdose and mainly affects the CNS (central nervous system) and the cardiovascular system. The underlying mechanism is the blockade of voltage-gated sodium channels, which massively disrupts the electrical excitability of nerve cells and cardiomyocytes. While dogs show moderate tolerance, cats are extremely sensitive, especially with oral or intravenous exposure. Lidocaine poisoning is a veterinary emergency and requires immediate symptomatic treatment, especially in cases of convulsions or circulatory weakness.<\/p>","symptome_einer_intoxikation":"Regarding the nervous system\n<ul>\n \t<li>Confusion<\/li>\n \t<li>Restlessness<\/li>\n \t<li>Tremors and<\/li>\n \t<li>Convulsions (tonic-clonic)<\/li>\n<\/ul>\nRegarding the cardiovascular system\n<ul>\n \t<li>Initially increased heart rate and blood pressure<\/li>\n \t<li>Later decrease in heart rate and blood pressure<\/li>\n \t<li>Cardiac arrhythmias<\/li>\n \t<li>Ventricular fibrillation<\/li>\n \t<li>Cardiac arrest (asystole)<\/li>\n \t<li>Coma<\/li>\n \t<li>Respiratory Arrest<\/li>\n<\/ul>\nThe clinical signs of lidocaine poisoning primarily affect the nervous system and the cardiovascular system, with neurological symptoms usually appearing first. Symptoms usually develop rapidly after exposure and can vary in severity depending on the degree of intoxication \/ poisoning.\n\nIn the CNS (central nervous system), affected animals initially show restlessness, disorientation and confusion. As plasma levels rise, muscle tremors (tremor), ataxia and coordination disorders may occur. In severe cases, tonic-clonic convulsions develop, which can progress to coma. These neurological symptoms result from blockade of inhibitory neurons in the CNS (central nervous system), leading to overactivity of excitatory systems.\n\nCardiovascular effects typically begin with initial tachycardia and hypertension, followed by progressive bradycardia and hypotension with ongoing exposure. By blocking sodium channels in the heart muscle, disturbances in impulse conduction occur, which can manifest as various arrhythmias. In severe cases, ventricular fibrillation and ultimately cardiac arrest can occur. These cardiovascular effects are particularly dangerous because they can persist even after the neurological symptoms have subsided.\n\nIn cats, symptoms may last longer and be more severe due to delayed breakdown of lidocaine. In addition, gastrointestinal symptoms such as vomiting and drooling may occur, especially after oral ingestion of the active ingredient.","diagnose_gift":"Diagnosis of lidocaine poisoning is based primarily on the medical history, clinical signs, and ruling out other causes. A thorough discussion with the owner is crucial to obtain information about possible sources of exposure, timing of exposure, and the estimated amount ingested.\n\nThe clinical exam includes a full neurological evaluation and cardiovascular assessment. Particular attention is paid to heart rate, heart rhythm, and blood pressure. An electrocardiogram is an important diagnostic tool because lidocaine can cause characteristic changes, including sinus bradycardia, prolonged PR intervals, widened QRS complexes, and various forms of heart block.\n\nLaboratory tests mainly serve to rule out other causes and assess organ function. A complete blood count, serum electrolytes, kidney values and liver values should be measured to assess the patient\u2019s overall condition and detect possible complications. Direct measurement of lidocaine plasma levels is rarely available in veterinary practice and is often not timely enough for acute treatment.\n\nDifferential diagnoses include other poisonings (especially from other local anesthetics, antiarrhythmics, or CNS-active substances), metabolic disorders, primary neurological diseases, and primary cardiac arrhythmias. The temporal correlation between exposure and onset of symptoms, the characteristic pattern of clinical signs, and the response to therapy support the diagnosis.","therapeutische_prinzipien":"After oral ingestion of lidocaine, decontamination by inducing vomiting, administering activated charcoal and\/or intestinal lavage depends on the time that has passed between ingestion of lidocaine and presentation to the veterinarian.\nThere is no antidote.\nTherapy is symptomatic.\nIn the event of cardiac arrest, immediate resuscitation is required.\nBecause cats break down lidocaine more slowly, cardiovascular monitoring needs to be extended and repeated resuscitation may be necessary.\nIn human medicine, intravenous lipids are administered immediately after successful resuscitation.\nThe effect of a lipid infusion is explained by the binding of fat-soluble lidocaine molecules to the infused lipids.\nSeizures and tremor are controlled with medication so that symptoms are relieved as much as possible, but deep anesthesia is not the goal. By repeatedly giving smaller individual doses and combining several medications, the dose of anticonvulsants can be reduced and the risk of side effects minimized.\n\nSupplements\n\nTreating lidocaine poisoning requires a fast, structured approach. Since there is no specific antidote, therapy is based on three pillars: decontamination, symptomatic treatment, and supportive measures.\n\nIf oral ingestion was recent, decontamination can be performed by inducing vomiting (only in an alert animal and within the first 1\u20132 hours) and administering activated charcoal (1\u20134 g\/kg body weight). With dermal exposure, the affected area should be thoroughly rinsed with lukewarm water to remove any remaining lidocaine.\n\nSymptomatic therapy is guided by the predominant clinical signs. For convulsions, anticonvulsants such as diazepam (0.5\u20132 mg\/kg IV) or phenobarbital (2\u20136 mg\/kg IV) are used. It is important to titrate the dose to avoid excessive respiratory depression. For cardiovascular complications, specific antiarrhythmics may be indicated depending on the type of arrhythmia. For bradycardia, atropine (0.02\u20130.04 mg\/kg IV) can be administered, while hypotension is treated with fluid therapy and, if needed, vasopressors.\n\nA promising therapy option for severe lidocaine poisoning is intravenous lipid infusion (Lipid Rescue Therapy). This treatment is based on the principle that lipophilic substances such as lidocaine can be bound in a lipid emulsion, reducing their plasma concentration and thus their toxic effect. The protocol typically includes an initial bolus of 20% lipid emulsion (1.5 ml\/kg over 1\u20132 minutes), followed by a continuous infusion (0.25 ml\/kg\/min for 30\u201360 minutes).\n\nSupportive measures include fluid therapy to promote renal elimination, oxygen supplementation in hypoxia, and in severe cases possibly mechanical ventilation. Continuous monitoring of vital signs, especially heart function, is essential in order to respond quickly to changes.","prognose":"The prognosis is good.\n\nWith early recognition and appropriate treatment, the prognosis for lidocaine poisoning is generally favorable. The course and chances of recovery depend largely on the amount ingested, the time to start of therapy, and the animal\u2019s individual health status.\n\nWith mild to moderate poisoning, complete recovery without long-term effects is usually expected after successful treatment. Neurological symptoms usually resolve within 24 hours, while cardiovascular effects may persist somewhat longer. In cats, the recovery phase may be prolonged due to their delayed metabolism.\n\nSevere intoxication \/ poisoning with prolonged convulsions or serious cardiac arrhythmia can potentially lead to permanent neurological damage or myocardial impairment. In such cases, close follow-up with regular cardiology and neurological check-ups is indicated.\n\nFollow-up initially includes inpatient monitoring for at least 24\u201348 hours after the acute symptoms have subsided, especially in cats. After discharge, owners should watch for possible relapses or delayed-onset symptoms. These include subtle neurological abnormalities such as changes in behavior, coordination disorders or weakness, as well as signs of heart problems such as reduced performance, cough or shortness of breath.\n\nPreventive measures to avoid re-exposure are an essential part of follow-up care. These include safely storing medications out of pets\u2019 reach and educating owners about the risks of self-medicating their animals with human products.","zusammenfassung_gift":"Lidocaine poisoning is a relevant toxicological problem in small animal medicine and can result from both medical use and accidental exposure. The active ingredient blocks sodium channels, thereby impairing impulse conduction in nerve and heart muscle cells. Cats in particular are at risk due to their limited metabolism.\n\nClinical signs primarily affect the nervous system with symptoms such as restlessness, tremor and convulsions, and the cardiovascular system in the form of arrhythmia and blood pressure changes. Diagnosis is based mainly on the medical history and the characteristic symptom pattern, supported by electrocardiogram examinations.\n\nTherapy includes decontamination measures, symptomatic treatment of neurological and cardiovascular symptoms, and supportive measures. Intravenous lipid therapy has proven to be a promising treatment option in severe intoxication \/ poisoning.\n\nWith early recognition and appropriate treatment, the prognosis is favorable, although recovery time in cats may be longer due to their delayed metabolism. Follow-up care focuses on monitoring possible long-term effects and prevention of renewed exposure.\n\nFor veterinarians and pet owners, it is important to know the risks of lidocaine and to take species-specific differences into account when using it. Careful dosing and safe storage of lidocaine-containing products are crucial to prevent poisoning cases.","ausblick_gift":"Research into lidocaine toxicity in small animals is continuously evolving, with several promising approaches being pursued. One focus is on optimizing Lipid Rescue Therapy, which has been increasingly adopted in veterinary practice in recent years. Current studies are investigating the optimal dosage, administration rate, and composition of lipid emulsions for different animal species and degrees of poisoning.\n\nAnother area of research involves developing specific biomarkers for early detection of local anesthetic-induced toxicities. These could help identify at-risk patients early and initiate preventive measures. In parallel, new lidocaine formulations with improved pharmacokinetic properties and lower toxicity potential are being researched, tailored specifically to the needs of different animal species.\n\nSpecial attention is also being paid to genetic factors that influence individual sensitivity to lidocaine. By identifying genetic polymorphisms associated with an increased risk of poisoning, personalized dosing regimens could be developed in the future to minimize toxicity risk.\n\nIntegrating point-of-care tests for rapid measurement of lidocaine plasma levels in veterinary practice could improve diagnostic certainty and enable more targeted therapy. Such rapid tests are currently in development and may become available in the coming years.\n\nLast but not least, research is also focusing on the long-term prognosis after surviving lidocaine poisoning. Longitudinal studies are examining possible subtle neurological or cardiac sequelae and their impact on the affected animals\u2019 quality of life.","weitere_inhalte_hauptteil":"","haufig_gestellte_fragen_faqs":"<ol>\n \t<li><strong> How quickly do the symptoms of lidocaine poisoning appear?<\/strong><\/li>\n<\/ol>\nSymptoms of lidocaine poisoning can occur very quickly.
