Nasotracheal intubation under curve-tipped suction catheter guidance reduces epistaxis . BACKGROUND Nasotracheal intubation ( NTI ) has greater potential for trauma of nasopharyngeal mucosa than orotracheal intubation . The present study investigated the success rate of NTI and frequency of nasal bleeding using a curve-tipped suction catheter ( CTSC ) to guide nasotracheal tube advancement . METHODS Subjects comprised 131 adult patients who under-went NTI . Subjects were randomly divided into two groups : a ) NTI under CTSC guidance ( G [ + ] group ) . The CTSC ( 14 Fr ) was first inserted through the tracheal tube , with the tip of the CTSC emerging from the distal end of the tube . The curved tip was directed ventrally . Both tracheal tube and CTSC were advanced together through the nasopharynx ; b ) NTI without CTSC guidance ( G [ - ] group ) . The tracheal tube was advanced into the nasal cavity and passed into the pharynx without CTSC guidance . The time required to pass the endotracheal tube through the nasal cavity ( nasal passage time ) , success rate of nasal passage with nasotracheal tube , and the incidence and severity of nasal bleeding were compared . RESULTS Success rate for nasal passage was 100 % in the G ( + ) group ( 62/62 ) and 82.6 % in the G ( - ) group ( 57/69 ; P = 0.0006 ) . Frequency of nasal bleeding was significantly lower in the G ( + ) group ( 21/62 , 33.9 % ) than in the G ( - ) group ( 37/69 , 53.6 % ; P = 0.023 ) . Severity of nasal bleeding was also significantly lower in the G ( + ) group than in the G ( - ) group ( P = 0.030 ) . CONCLUSIONS Nasotracheal intubation under CTSC guidance increases the success rate of airway instrumentation , and also reduces the incidence and severity of epistaxis .
