ABSTRACT
Objective:To evaluate the efficacy of visual laryngoscope for tracheal intubation for resuscitation in the premature infants born within 32 weeks of gestation.Methods:A total of 84 premature infants who were born < 32 weeks of gestation in the Third Affiliated Hospital of Zhengzhou University and required tracheal intubation after birth from January 2019 to December 2021 were enrolled and divided into direct laryngoscope group and visual laryngoscope group according to the random number table method, with 42 cases in each group.The glottis exposure, intubation time, successful tracheal intubation at first attempt and complications related to intubation were recorded in the two groups.Results:Compared with direct laryngoscope group, the time of glottis exposure and tracheal intubation was significantly shortened, and the success rate of endotracheal intubation at first attempt was increased in visual laryngoscope group ( P<0.05).There was no significant difference in the glottis exposure during laryngoscope-assisted intubation and incidence of complications related to tracheal intubation between the two groups ( P>0.05). Conclusions:Visual laryngoscope provides better efficacy than direct laryngoscope when used for tracheal intubation for resuscitation in the premature infants born within 32 weeks of gestation.
