Abstract：Objective To explore the application effect of minimally invasive meconium aspiration technique in neonates with third-degree fecal staining of amniotic fluid.Methods A total of 86 newborns admitted to the neonatal intensive care unit after birth with third-degree amniotic fluid in the Department of Obstetrics of Pengpai Memorial Hospital of Haifeng County Affiliated to Guangdong Medical University from January to June 2019 were selected as the research subjects.They were divided into the observation group (n=43) and the control group (n=43) by the random number table method.Both groups underwent meconium aspiration on the assessment of inactivity.In the control group,the common tracheal intubation followed by a meconium aspirator was used,and in the observation group,the minimally invasive meconium aspiration technique was adopted,that was,guiding the suction tube into the glottis under the laryngoscope for meconium suction.The number of meconium suctions,operation time,clinical symptoms after treatment,chest radiograph results,hospitalization time and incidence of complications were compared in the two groups.Results There was no statistically significant difference in the number of meconium suctions between the two groups (P＞0.05).The operation time of the observation group was shorter than that of the control group,and the difference was statistically significant (P＜0.01).There was no statistically significant difference in the proportion of requiring ventilator assisted ventilation between the two groups (P＞0.05).The proportion of laryngeal injuries (edema or hemorrhage) in the observation group was lower than that in the control group,and the difference was statistically significant (P＜0.05).The results of chest radiograph between the two groups indicated that there was no statistical difference in the proportion of meconium aspiration syndrome or the proportion of air leak syndrome (P＞0.05).There was no statistically significant difference in hospitalization time between the two groups (P＞0.05).Conclusion The minimally invasive meconium suction technique is safe and effective for amniotic fluid third-degree fecal-stained and inactive newborns who do not need tracheal intubation to resuscitate after birth,the operation time is short,and the incidence of complications such as laryngeal injuries after operation is lower.
