With increasing improvement in perioperative care, post-surgical complication and mortality rates have continued to decline in the United States. Nonetheless, not all racial groups have benefitted equally from this transformative improvement in postoperative outcomes. We tested the hypothesis that among a cohort of "sick" (ASA physical status 4 or 5) Black and White children, there would be no systematic difference in the incidence of postoperative morbidity and mortality. ⋯ In this cohort of children with high ASA physical status, Black children compared to their White peers experienced significantly higher rates of 30-day postoperative morbidity and mortality. These findings suggest that racial differences in postoperative outcomes among the sickest pediatric surgical patients may not be entirely explained by preoperative health status.

To minimize the risk of cervical spinal cord injury in patients who have cervical spine pathology, minimizing cervical spine motion during laryngoscopy and tracheal intubation is commonly recommended. However, clinicians may better aim to reduce cervical spinal cord strain during airway management of their patients. The aim of this study was to predict laryngoscope force characteristics (location, magnitude, and direction) that would minimize cervical spine motions and cord strains. ⋯ The model predicts clinicians can most effectively minimize cervical spine motion and cord strain during laryngoscopy by decreasing laryngoscope force magnitude. Very low force magnitudes (<5 N, ~10% of routine) are necessary to decrease overall cervical extension to <50% of routine values. Force magnitudes ≤24.4 N (≤50% of routine) are predicted to help prevent potentially injurious compressive cord strain.
