About
Patients scheduled for cardiac surgery are fragile. Hemodynamic fluctuation might be associated with adverse outcomes. Therefore, it is essential to keep hemodynamics stable during and after the induction period. Previous studies have shown that topical anesthesia can provide excellent superior supraglottic and subglottic local anesthetic effects and can significantly reduce the dosage of intravenous anesthetics. Therefore, we designed this study to explore whether the combination of topical anesthesia and intravenous anesthetics could decrease the stress response of endotracheal intubation and keep hemodynamics stable during and after the induction period.
Full description
Patients scheduled for cardiac surgery are often accompanied by cardiac insufficiency. Hemodynamic fluctuation might lead to disastrous events. Therefore, it is essential to keep hemodynamics stable during and after the induction period. The routine anesthesia induction strategy for cardiac surgery is to decrease stress response during endotracheal intubation by using large doses of opioids. However, high doses of opioids often leads to persistent and recurrent hypotension in patients from the anesthesia induction period to the beginning of the surgery. Previous studies have shown that topical anesthesia can provide excellent superior supraglottic and subglottic local anesthetic effects and can significantly reduce the dosage of intravenous anesthetics. Therefore, we designed this study to explore whether the combination of topical anesthesia and intravenous anesthetics could decrease the stress response of endotracheal intubation and keep hemodynamics stable during and after the induction period.
