Comparison of IV Lignocain and IV Dexmedetomidine for Attenuation of Laryngoscopic Stress Response to Direct Laryngoscopy

Summary

Hemodymanic stress response to direct laryngoscopy and endotracheal intubation is a known phenomenon that occur in almost every patient undergoing general anesthesia before surgical procedure. This response leads to sudden rise in heart rate and blood pressure which may cause serious complications in compromised patients having cardiovascular diseases. There are certain drugs which are used to blunt this response and to prevent the life threatening complications. Intravenous Lignocain is commonly used drug to blunt the laryngoscopic response in our setup. Intravenous Dexmedetomidine is a newer and rarely used drug to prevent stress response to direct laryngoscopy and endotracheal intubation. This study aims to compare the efficacy of both the drugs to provide better control of complications like Arrythmias, stroke and cardiovascular instability.
