Tracheal extubation under intravenous xylocaine

Area of Science:

• Anesthesiology
• Cardiology
• Critical Care Medicine

Background:

• Tracheal extubation can precipitate adverse circulatory changes, particularly in patients with coronary artery disease (CAD) or multiple cardiac risk factors.
• Managing hemodynamic stability during extubation is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the effect of intravenous lidocaine (xylocaine) on the quality of tracheal extubation.
• To assess circulatory changes during extubation in patients with CAD or cardiac risk factors, with and without prior lidocaine administration.

Main Methods:

• A study involving 30 patients with CAD or at least two cardiac risk factors.
• Patients received either intravenous lidocaine (1 mg/kg) or a placebo (control group) before extubation.
• Extubation quality was graded, and circulatory changes, including rate pressure product, were monitored.

Main Results:

• A significantly higher proportion of patients receiving lidocaine experienced smooth extubation (Grade I) compared to the control group (73.33% vs. 46.66%).
• The lidocaine group exhibited statistically insignificant circulatory changes post-extubation.
• The control group showed a highly significant increase in the rate pressure product, indicating greater hemodynamic stress.

Conclusions:

• Intravenous lidocaine administration improves the quality of tracheal extubation in patients with CAD or cardiac risk factors.
• Lidocaine attenuates adverse circulatory responses during extubation, contributing to improved hemodynamic stability.
• These findings suggest lidocaine as a valuable adjunct for smoother and safer extubation in at-risk cardiac patients.
