Adverse Tracheal Intubation Events in Critically Ill Underweight and Obese Children: Retrospective Study of the National Emergency Airway for Children Registry (2013-2020)

OBJECTIVES

Extremes of patient body mass index are associated with difficult intubation and increased morbidity in adults. We aimed to determine the association between being underweight or obese with adverse airway outcomes, including adverse tracheal intubation (TI)-associated events (TIAEs) and/or severe peri-intubation hypoxemia (pulse oximetry oxygen saturation < 80%) in critically ill children.

DESIGN/SETTING

Retrospective cohort using the National Emergency Airway for Children registry dataset of 2013-2020.

PATIENTS

Critically ill children, 0 to 17 years old, undergoing TI in PICUs.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Registry data from 24,342 patients who underwent TI between 2013 and 2020 were analyzed. Patients were categorized using the Centers for Disease Control and Prevention weight-for-age chart: normal weight (5th-84th percentile) 57.1%, underweight (< 5th percentile) 27.5%, overweight (85th to < 95th percentile) 7.2%, and obese (≥ 95th percentile) 8.2%. Underweight was most common in infants (34%); obesity was most common in children older than 8 years old (15.1%). Underweight patients more often had oxygenation and ventilation failure (34.0%, 36.2%, respectively) as the indication for TI and a history of difficult airway (16.7%). Apneic oxygenation was used more often in overweight and obese patients (19.1%, 19.6%) than in underweight or normal weight patients (14.1%, 17.1%; p < 0.001). TIAEs and/or hypoxemia occurred more often in underweight (27.1%) and obese (24.3%) patients ( p < 0.001). TI in underweight children was associated with greater odds of adverse airway outcome compared with normal weight children after adjusting for potential confounders (underweight: adjusted odds ratio [aOR], 1.09; 95% CI, 1.01-1.18; p = 0.016). Both underweight and obesity were associated with hypoxemia after adjusting for covariates and site clustering (underweight: aOR, 1.11; 95% CI, 1.02-1.21; p = 0.01 and obesity: aOR, 1.22; 95% CI, 1.07-1.39; p = 0.002).

CONCLUSIONS

In underweight and obese children compared with normal weight children, procedures around the timing of TI are associated with greater odds of adverse airway events.

Interval laparoscopic appendectomy for appendicitis complicated by pylephlebitis

BACKGROUND

Although rare, portal mesenteric venous thrombosis and pylephlebitis remain potential life-threatening sequelae of ruptured appendicitis in children. Treatment recommendations from recent reports have included urgent exploratory laparotomy with appendectomy, prolonged intravenous antibiotic therapy, and anticoagulation for up to a year.

METHODS

This report describes successful management of pylephlebitis and mesenteric venous thrombosis complicating ruptured appendicitis with intravenous antibiotics and anticoagulation followed by interval laparoscopic appendectomy.

RESULTS

A previously healthy 5-year-old girl was diagnosed with ruptured appendicitis complicated by pylephlebitis and mesenteric venous thrombosis at the time of presentation. She was treated with intravenous antibiotics and anticoagulated for 3 months. She subsequently underwent interval laparoscopic appendectomy. At 3-year follow-up, she is healthy without evidence of adverse sequelae.

DISCUSSION

This is the first reported case of successful, minimally invasive management of ruptured appendicitis complicated by mesenteric venous thrombosis and pylephlebitis.

CONCLUSION

Similar treatment of other children with this rare presentation seems reasonable.

"Narrowing the Gap": decreasing emergency department use by children enrolled in the Medicaid program by improving access to primary care

OBJECTIVE

To evaluate the effectiveness of increased primary care access created by North Carolina's Medicaid managed care plan, Carolina Access (CA), in reducing unnecessary emergency department (ED) use in Guilford County.

METHODS

Emergency department records of pediatric visits before and after the implementation of CA were analyzed. Variables included patient age, International Classification of Diseases, Ninth Revision discharge diagnosis, insurance status, date of visit, time of visit, and ZIP code. Visits were classified as either urgent or nonurgent based on discharge diagnosis. Rates of ED use per 1000 persons were calculated using county population and Medicaid enrollment figures.

RESULTS

A total of 54,742 ED visits occurred between January 1, 1995, and December 31, 1997. Thirty-eight percent of these visits were by children (defined as those aged 0-18 years in this study) enrolled in the Medicaid program. After the implementation of CA, monthly ED rates per 1000 children with Medicaid insurance decreased 24% from 33.5 +/- 5.3 to 25.6 +/- 2.3 (P<.001), which translates to 158 fewer visits per month by children enrolled in the Medicaid program. Nonurgent visits among the population enrolled in the Medicaid program decreased from an average monthly rate per 1000 of 17.9 +/- 3.5 to 11.2 +/- 2.5 after the implementation of CA (P<.001), accounting for most of the decrease in total visits. (All data are given as mean +/- SD.) The rates of total and nonurgent visits among the population not enrolled in the Medicaid program increased slightly.

CONCLUSIONS

For children with Medicaid insurance, we found a strong temporal relation between decreased visits to the ED and increased access to primary care services, services that were made available by the implementation of North Carolina's Medicaid managed care plan, CA. Specific services that may be responsible for the decreased ED use include the expanded availability of primary care physicians and the use of telephone triage systems. No similar decrease in ED use was seen among the non-Medicaid-insured group. Arch Pediatr Adolesc Med. 2000;154:791-795
