- Dosage
- <p><strong>Dosage and Administration:</strong><br>
Lidocaine Injection is for one dose in one patient only, discard any remaining contents.</p>
<p><u>As a local anaesthetic for infiltration and nerve block:</u><br>
The dosage varies and depends upon the area to be anaesthetised, vascularity of the tissues, number of neuronal segments to be blocked, individual tolerance and the technique of anaesthesia. The lowest dose needed to provide effective anaesthesia should be administered. For specific techniques and procedures, refer to standard textbooks.<br>
It is recommended that the dose of lidocaine at any one time should not exceed 3mg/kg. However, the dose administered must be tailored to the individual patient and procedure, and the maximum doses here quoted should be used as a guide only.</p>
<p><u>Adult</u><br>
The normal recommended dosage of lidocaine for various anaesthesic procedures in average, healthy 70kg adult patients are as follows:</p>
<img src="/TGIF/Lycan-Table1.png" alt="Lycan Sodium Dosage Table 1" /><br><br>
<p>The doses suggested above are only a guide. Toxic levels vary widely between patients so doses should be individualised and blood levels should be monitored.<br>
Epidural injections should be administered slowly with frequent aspirations. Subarachnoid and intravascular injections are two of the most serious complications of this technique. If blood or spinal fluid become manifest during aspiration, the needle must be withdrawn and relocated.</p>
<p>The technique of epidural anaesthesia should only be attempted by physicians skilled in this area and readiness for emergencies must be ensured. During spinal anaesthesia the positioning of the patient is very important and the patient's pulse and blood pressure should be monitored. During thoracic, lumbar and caudal epidural anaesthesia, a marked fall in blood pressure and/or intercostal paralysis may be seen, possibly due to the use of excessive doses, improper positioning of the patient or accidental disposition of the anaesthetic within the subarachnoid space. Hypotension and bradycardia may occur as a result of sympathetic blockade.</p>
<p>For continuous epidural or caudal anaesthesia and paracervical block for obstetric analgesia the maximum dose should not be repeated at intervals of less than 1.5 hours.<br>
Adults: The dose should not exceed 200mg. For spinal anaesthesia, the dose should not exceed 100mg.<br>
Children: For children, a reduced dosage based on body weight or surface area should be used. The dosage should be calculated for each patient individually and modified in accordance with the physician’s experience and knowledge of the patient. Early signs of local anaesthetic toxicity may be difficult to detect in cases where the block is given during general anaesthesia. In order to minimise the possibility of toxic effects, the use of Lidocaine Injection 1% is recommended for most anaesthetic procedures involving paediatric patients.</p>
<p>The dose should not exceed 3mg/kg.</p>
<p><u>For intravenous use in cardiac arrhythmias:</u><br>
Patients with congestive heart failure or cardiogenic shock may require smaller bolus doses.<br>
Adults: The usual dose is lignocaine 50 to 100mg administered intravenously under ECG monitoring. The dose may be injected at a rate of approximately 25 to 50mg (1.25 to 2.5ml of the 2% solution) per minute. A sufficient period of time should be allowed to enable a slow circulation to carry the drug to the site of action. If the initial dose of 50 to 100mg does not produce the desired response, a second dose may be given after five minutes. No more than 200 to 300mg of lignocaine should be administered during a one hour period.</p>
<p>Following a single injection in those patients in whom arrhythmia tends to recur and who are incapable of receiving oral antiarrhythmic therapy, intravenous infusions of lignocaine may be administered at a rate of 1 to 4mg/minute (20 to 50 mcg/kg/minute). Intravenous infusions must be given under ECG monitoring to avoid potential overdosage and toxicity. The infusion should be terminated as soon as the patient’s cardiac rhythm appears to be stable or at the earliest signs of toxicity. It should rarely be necessary to continue the infusion beyond 24 hours. As soon as possible, patients should be changed to an oral antiarrhythmic agent for maintenance therapy.<br>
Paediatrics: For children, a reduced dose based on body weight or surface area should be used. It is recommended that the 1% solution be used to minimise the possibility of toxic effects. Experience with lidocaine is limited.</p>
<p><u>Use in elderly</u><br>
A reduction in dosage may be necessary for elderly patients especially those with compromised cardiovascular and/or hepatic function.</p>
<p><u>Impaired hepatic function</u><br>
Although lidocaine is metabolised by the liver, dosage reduction for local anaesthesia is probably not warranted. However, caution should be exercised with repeated doses.</p>
<p><u>Impaired renal function</u><br>
Impairment of renal function is unlikely to affect lidocaine clearance in short term (24 hours). However, toxicity due to accumulation may develop with prolonged or repeated administration.</p>
<p><strong>Route of Administration:</strong><br>
The method of administration of Lignocaine varies according to the procedure (infiltration anaesthesia, intravenous regional anaesthesia or nerve block).</p>
- Route Of Administration
- INTRAVENOUS, INFILTRATION
- Indication Info
- <p><strong>Indication(s):</strong><br>
Lidocaine is intended for the production of local or regional anaesthesia by nerve block, infiltration injection, caudal or other epidural blocks:<br>
Treatment or prophylaxis of life-threatening ventricular arrhythmias, including those associated with myocardial infarction, general anaesthesia in patients predisposed to ventricular arrhythmias, digitalis intoxication, or following resuscitation from cardiac arrest.</p>
- Contraindications
- <p><strong>Contraindication(s):</strong></p>
<ol>
<li>Hypersensitivity to the active substance, to anaesthetics of the amide type or to any of the excipients.</li>
<li>Lidocaine is contraindicated in patients with complete heart block and hypovolaemia.</li>
<li>Inflammation or sepsis at the proposed site of injection and in the presence of septicaemia.</li>
<li>Patients with myasthenia gravis, severe shock or impaired cardiac conduction.</li>
<li>Epidural or spinal anaesthesia in patients with
<ul class="bullet">
<li>uncorrected hypotension or</li>
<li>coagulation disorders or receiving anticoagulants or</li>
<li>serious diseases of the central nervous system or spinal cord such as meningitis, spinal fluid block, cranial or spinal haemorrhage, tumours, poliomyelitis, syphilis, tuberculosis or metastatic lesions of the spinal cord.</li></ul>
</li>
<li>Antiarrhythmic use in patients with
<ul class="bullet">
<li>supraventricular arrhythmia or</li>
<li>Stokes – Adams syndrome or severe degrees of sinoatrial, atrioventricular or intraventricular block unless the patient has an artificial pacemaker.</li></ul>
</li>
<li>Lidocaine suppresses ventricular pacemaker activity and may cause ventricular standstill in such patients.</li>
<li>General contraindications related to epidural anaesthesia, regardless of the local anaesthetic used, should be taken into account.</li>
