Abstract

During the administration of general anesthesia, direct laryngoscopy and endotracheal intubation cause an increase in heart rate, arterial pressure, and dysrhythmias in upto 90% of patients. These changes can be particularly hazardous for patients with cerebral or coronary diseases. Both clonidine and gabapentin have been used for anesthetic effects, but a better drug for controlling hemodynamic parameters is being investigated. The study was done to evaluate and compare the efficacy of oral clonidine 0.3 mg and oral gabapentin 900 mg as a premedication for attenuation of pressor response to laryngoscopy and endotracheal intubation. After obtaining approval from the ethics committee, 75 patients, American Society of Anesthesiologists physical status classes I and II between the ages of 18 and 60 years scheduled to undergo elective noncardiac surgical procedure were enrolled in the study. Patients were randomized into three groups of 25 each who received 0.3 mg clonidine, 900 mg gabapentin, and placebo. The hemodynamic parameters were recorded at various time intervals along with any adverse effects. Quantitative variables were compared using unpaired t-test between the two groups and ANOVA for three groups. Qualitative variable...Continue Reading

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
