What must be monitored closely when administering Lidocaine?

When administering Lidocaine, close monitoring of heart rhythm is crucial due to its primary use as an antiarrhythmic medication. Lidocaine works by stabilizing the cardiac membrane and is effective in treating ventricular arrhythmias. During administration, it is essential to observe for any changes in the heart rhythm, such as the development of new arrhythmias or the resolution of existing ones.

Monitoring the heart rhythm allows healthcare providers to assess the efficacy of the drug and to detect any potential side effects, including toxicity, which can lead to further arrhythmias or complications. Vigilant observation enables timely intervention if any adverse effects occur, ensuring patient safety and optimal therapeutic outcomes.
