Guest guest Posted August 10, 2011 Report Share Posted August 10, 2011 Amazing thanksSent from my BlackBerry Torch® wireless deviceFrom: Mandy F <drmandysul@...>Sender: Date: Wed, 10 Aug 2011 21:15:52 +0100 (BST) < >Reply Subject: LA overdose FYISigns and Symptoms of Local Anaesthetic ToxicityThe systemic toxic effects due to local anaesthetic overdose primarily involve the central nervous and cardiovascular systems. In general the Central Nervous System (CNS) is more sensitive to local anaesthetics than the Cardiovascular System (CVS). Therefore CNS manifestations tend to occur earlier. Brain excitatory effects occur before the depressant effects.CNS signs & symptomsEarly or mild toxicity: light-headedness, dizziness, tinnitus, circumoral numbness,abnormal taste, confusion and drowsiness. Patients often will not volunteer information about these symptoms unless asked. Throughout the injection talk to the patient asking them how they feel. Any suggestion of confusion should alert you to the possibility of toxicity and you should stop any further injection.Severe toxicity: tonic-clonic convulsion leading to progressive loss of consciousness, coma, respiratory depression, and respiratory arrest.Depending on the drug and the speed of the rise in blood level the patient may go from awake to convulsing within a very short time.Hope it helps:) Quote Link to comment Share on other sites More sharing options...
