Risk of post-tonsillectomy hemorrhage among COVID-19 positive pediatric patients.

OBJECTIVE: COVID-19 infection has been demonstrated to increase risk for post-operative bleeding. This study investigated the impact of COVID-19 infection on post-tonsillectomy hemorrhage in pediatric patients, a potentially devastating complication. STUDY DESIGN: Retrospective cohort study. METHODS: The TriNetX database was queried for pediatric patients who underwent tonsillectomy and evaluated for outcomes of primary and secondary post-tonsillectomy hemorrhage. RESULTS: Among subjects 18 years and younger, 1226 were COVID-19 positive and 38,241 were COVID-19 negative in the perioperative period. There was statistically significant increased risk of bleeding with perioperative COVID-19 infection at postoperative days 1, 5, and 10. Additionally, when assessing the role of COVID-19 infection before or after surgery, the risk of bleeding remained statistically significant at all three time points, however these results did not suggest that infection before surgery confers more/less risk compared to infection after. CONCLUSION: The results of this investigation suggest that the presence of COVID-19 in the perioperative period may pose an increased risk for acute or delayed post tonsillectomy hemorrhage. This study employed a large, diverse population and is the first to address this clinical question.

Demographic Differences in Clinical Presentation of Pediatric Paradoxical Vocal Fold Motion (PVFM).

OBJECTIVES: Paradoxical vocal fold motion (PVFM) is involuntary closure of the vocal folds during inspiration, often presenting in children and young adults. Although common symptoms and triggers are known, differences in clinical presentation based on patient demographics are unknown. This study characterizes differences in clinical presentation of pediatric PVFM based on age, sex, and race/ethnicity. METHODS: We reviewed electronic medical records of patients 0-21 years old with PVFM based on ICD codes from 2009 to 2019 within a tertiary academic health system. Demographics, symptoms, triggers, concurrent diagnoses, and laryngoscopy findings were abstracted. Odds ratios (ORs) and 95% confidence intervals (CI) were estimated using logistic regression. RESULTS: Among 96 individuals the mean age was 10.6 years (standard deviation ±6.5) and 66 (69%) were female. In comparison to 13-21 year olds, those 0-2 years more often had PVFM observed on laryngoscopy (OR = 17.84, 95% CI: 3.14-101.51) and had less shortness of breath (OR = 0.01, 95% CI: 0.00-0.09). Those 3-12 years had more asthma (OR = 3.07, 95% CI: 1.07-8.81) and cough (OR = 6.12, 95% CI: 1.77-21.13). Both 0-2 (OR = 0.07, 95% CI: 0.02-0.24) and 3-12 year olds (OR = 0.13, 95% CI: 0.04-0.40) presented less with activity as a trigger. Racial/ethnic minorities were more likely to present with pharyngeal findings (eg mucosal inflammation, adenotonsillar hypertrophy) on laryngoscopy (OR = 4.58, 95% CI: 1.45-15.37) compared to non-Hispanic Whites. Differences in clinical presentation by sex were not observed. CONCLUSION: We identified several differences in symptoms, triggers, and laryngoscopy findings in pediatric PVFM based on age and race/ethnicity. Associations between sex and clinical presentation were not observed.

Determining the utility of standard hospital microbiology testing: Comparing standard microbiology cultures with DNA sequence analysis in patients with chronic sinusitis.

OBJECTIVE: To demonstrate DNA sequencing analysis (DNAsa) of sinus cultures in patients with CRS is a reliable method of detecting pathogens in polymicrobial CRS infections. METHODS: After obtaining Institutional Review Board approval for this prospective cohort study, we selected a random sample of 50 patients with CRS at Medstar Georgetown University Hospital between September 2016 and March 2017. We defined CRS as a history of rhinosinusitis refractory to maximal medical therapy and prior endoscopic sinus surgery. Patients demonstrating active purulence in a sinus cavity were prospectively selected to undergo standard hospital cultures (SHC) and DNAsa cultures. Organisms identified in both methods were compared for each patient. RESULTS: Specimens were obtained from 29 female and 16 male patients with a mean age of 50 years. A total of 45 cultures were included in our final analysis; five cultures were excluded after inappropriate laboratory processing. Results from these patients were compared and analyzed. Cohen's weighted kappa analysis showed agreement between the two testing methods in identifying predominant microorganisms. DNAsa detected 31.9% more microorganisms compared to SHC (P < 0.05). When multiple microorganisms were detected, DNAsa yielded more positive results compared to SHC (P < 0.05). CONCLUSIONS: DNAsa detects all microorganisms identified by SHC as well as predominant microorganisms not detected by SHC. Thus molecular pathogen identification may be more reliable for identifying multiple microorganisms as compared to standard culture techniques that identify only one or two microorganisms. In recalcitrant cases of CRS, DNAsa may provide better guidance in selection of appropriate antimicrobial treatment.

Tracheostomy manipulations: Impact on tracheostomy safety.

IMPORTANCE: Tracheotomy is one of the riskiest procedures for composite morbidity within pediatric otolaryngology. During the postoperative period, each time the tracheostomy tube is manipulated, there is opportunity for morbidity (e.g. a patient is vulnerable to accidental decannulation and airway loss). OBJECTIVE: To identify areas of improvement in caring for "fresh tracheostomy" patients by determining the number of times a tracheostomy tube is manipulated from placement until discharge. The hypothesis is that the more a tracheostomy is manipulated, the higher probability of morbidity. METHODS: A quality improvement initiative was conducted to map the care of patients who underwent tracheostomy placement over 12 months. Tracheostomy care and manipulation by all providers were reviewed. Complications, wound care, and respiratory treatments were also evaluated. RESULTS: Patients were hospitalized for an average of 39 days (7-140) following tracheostomy. The first tracheostomy tube change occurred on average 6 days (5-10) following placement. Tracheostomy tubes were manipulated an average of 6 (2.5-11.9) times a day to amount to 216 (51-1091) times between placement and discharge. Bedside nurses and respiratory therapists were responsible for 95% of these actions; physicians accounted for 4%. There were 6 tracheostomy related complications. Three were accidental decannulations resulting in cardiopulmonary arrest. One of these caused long term patient morbidity. Patients with more than 4 manipulations per day during the 2 weeks following tracheostomy tube placement, were more likely to have a tracheostomy related complication than those with less than 4 (OR: 12.5; 95% CI: 1.2-130.6; P = 0.0349). INTERPRETATION: While uncommon, complications related to tracheostomy can have serious long term effects and at best prolongs length of stay for patients. Reducing the number of tracheostomy manipulations may provide safer postoperative care ultimately reducing morbidity and potentially mortality; children on average have 6 tracheotomy manipulations/day with only 2% being by the physician.
