Vancouver, British Columbia—Preloading alkalinized lidocaine in the endotracheal tube (ETT) cuff significantly decreases emergence cough after general anesthesia in surgeries lasting less than an hour. The investigators also found an inverse relationship between opioid dose and the incidence of coughing.
“In the early 2000s, European studies showed that alkalinized lidocaine would diffuse out of the endotracheal tube cuff after 90 to 120 minutes,” said Papu Nath,
