Methods

This was a prospective, observational study. Children 18 years of age and under who presented to the pediatric emergency department (PED) and required PSA were enrolled. We obtained Mallampati scores as part of pre-PSA assessments. We defined adverse events as oxygen desaturation< 90%, apnea, laryngospasm, bag-valve-mask ventilation performed, repositioning of patient, emesis, and “other.” We used chi-square analysis to compare rates of adverse events between groups.

Results

We enrolled 575 patients. The median age of the patients was 6.0 years (interquartile range= 3.1, 9.9). The primary reasons for PSA was fracture reduction (n= 265, 46.1%). Most sedations involved the use of ketamine (n= 568, 98.8%). Patients with Mallampati scores of III/IV were more likely to need repositioning compared to those with Mallampati scores of I/II (p= 0.049). Overall, patients with Mallampati III/IV scores …
