Toxicity of local anesthetics
Systemic neurotoxicity due to excessive cerebral local anesthetic blood levels is one of the most severe and most frequent adverse outcome of local anesthetic use. Toxic levels are most often produced by unintentional intravenous or intraarterial injection(1,2). Toxicity can also result from the rapid absorption of drug following perineural injection. Peak blood levels are usually obtained acco...
متن کاملLocal Anesthetics Systemic Toxicity.
Lidocaine Hydrochloride is an amide ester, which is widely used local anesthetic agent that is well tolerated but what is less known is the occurrence of systemic toxicity which manifests in the central nervous and cardiovascular systems. We report here 3 cases of Lidocaine associated Seizures.
متن کاملCardiovascular Toxicity of Local Anesthetics
In general, much greater doses of local anesthetics are required to produce cardiovascular (CV) toxicity than CNS toxicity. Similar to CNS toxicity, potency for CV toxicity reflects the anesthetic potency of the agent. Recent attention has focused on the apparently exceptional cardiotoxicity of the more potent, more lipid-soluble agents (bupivacaine, levo-bupivacaine, etidocaine, ropivacaine). ...
متن کاملFetal toxicity of local anesthetics
This article reviews mechanisms by which local anesthetics may compromise the fetus during conduction analgesia in obstetrics. In addition to presenting pertinent information about perinatal pharmacology of local anesthetics, the author discusses comparative effects of 2-chloroprocaine and amide-linked compounds. Recommendations are made for prevention of maternal hypotension and local anesthet...
متن کاملCardiovascular toxicity of local anesthetics: an alternative hypothesis.
The current study examined the possibility that high local anesthetic concentrations within the central nervous system could contribute to the toxic cardiovascular effects observed clinically after an accidental intravenous injection. Equal numbers of molecules of lidocaine (1.6 microliter of a 2% solution) and bupivacaine (1.0 microliter of a 4% solution) were injected at three vasomotor and c...
