Lidocaine spray may reduce muscle relaxant needed for tube insertion

This study tested whether using a lidocaine spray along with a low dose of a muscle relaxant (cisatracurium) can make placing a breathing tube easier and safer during ERCP, a procedure for bile duct problems. 186 adults with liver issues were randomly assigned to receive either the low-dose combo or the standard muscle relaxant dose. The goal was to see if the combo could achieve good intubation conditions while using less medication, potentially speeding recovery and reducing side effects.
