Abstract
Obstructed breathing is the most common indication for tonsillectomy in children. Although tonsillectomy is performed frequently worldwide, the surgery is associated with a number of significant complications such as bleeding and respiratory failure. Complication risk depends on a number of complex factors, including indications for surgery, demographics, patient comorbidities, and variations in perioperative techniques. While polysomnography is currently accepted as the gold standard diagnostic tool for obstructive sleep apnea, studies evaluating outcomes following surgery suggest that more research is needed on the identification of more readily available and accurate tools for the diagnosis and follow-up of children with obstructed breathing.

Shaikh N, Kais A, Dewey J, Jaffal H. Effect of perioperative ketorolac on postoperative bleeding after pediatric tonsillectomy. Int J Pediatr Otorhinolaryngol 2024; 180:111953. [PMID: 38653108 DOI: 10.1016/j.ijporl.2024.111953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 03/28/2024] [Accepted: 04/11/2024] [Indexed: 04/25/2024]
Abstract
INTRODUCTION Ketorolac is a frequently used anesthetic pain agent which is traditionally avoided during tonsillectomy due to concern for postoperative hemorrhage. Our goal was to assess the degree of risk associated with the use of Ketorolac following pediatric tonsillectomy. METHODS The TriNetX electronic health records research database was queried in January 2024 for patients undergoing tonsillectomy with or without adenoidectomy under the age of 18 years and without a diagnosed bleeding disorder. Patients were separated into two cohorts either having received or not having received ketorolac the same day as surgery. Propensity score matching was performed for age at the time of surgery, sex, race, ethnicity, and preoperative diagnoses. The outcomes assessed were postoperative hemorrhage requiring operative control within the first day (primary hemorrhage) and within the first month after surgery (secondary hemorrhage). RESULTS 17,434 patients were identified who had undergone pediatric tonsillectomy with or without adenoidectomy and had received ketorolac the same day as surgery. 290,373 patients were identified who had undergone pediatric tonsillectomy with or without adenoidectomy and had not received ketorolac the same day as surgery. 1:1 propensity score matching resulted in 17,434 patients within each cohort. Receipt of ketorolac the same day as surgery resulted in an increased risk of primary hemorrhage OR 2.158 (95 % CI 1.354, 3.437) and secondary hemorrhage OR 1.374 (95 % CI 1.057, 1.787) requiring operative control. CONCLUSION Ketorolac use during pediatric tonsillectomy with or without adenoidectomy was associated with an increased risk of postoperative primary and secondary bleeding requiring surgery.

Abstract
OBJECTIVE To investigate the impact of the surgical indication on posttonsillectomy bleed rates. DATA SOURCES PubMed, Scopus, CINAHL. REVIEW METHODS A systematic review was performed searching for articles published from the date of inception to July 6, 2022. English language articles describing posttonsillectomy hemorrhage rates in pediatric patients (age ≤ 18) stratified by indication were selected for inclusion. A meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. All studies were assessed for risk of bias. RESULTS A total of 72 articles with 173,970 patients were selected for inclusion. The most common indications were chronic/recurrent tonsillitis (CT/RT), obstructive sleep apnea/sleep-disordered breathing (OSA/SDB), and adenotonsillar hypertrophy (ATH). Posttonsillectomy hemorrhage rates for CT/RT, OSA/SDB, and ATH were 3.57%, 3.69%, and 2.72%, respectively. Patients operated on for a combination of CT/RT and OSA/SDB had a bleed rate of 5.99% which was significantly higher than those operated on for CT/RT alone (Δ2.42%, p = .0006), OSA/SDB alone (Δ2.30%, p = .0016), and ATH alone (Δ3.27%, p < .0001). Additionally, those operated on for a combination of ATH and CT/RT had a hemorrhage rate of 6.93%, significantly higher than those operated on for CT/RT alone (Δ3.36%, p = .0003), OSA/SDB alone (Δ3.01%, p = .0014), and ATH alone (Δ3.98%, p < .0001). CONCLUSION Patients operated on for multiple indications had significantly higher rates of posttonsillectomy hemorrhage than those operated on for a single surgical indication. Better documentation of patients with multiple indications would help further characterize the magnitude of the compounding effect described here.

Estimated Probability Distribution of Bleeding After Pediatric Tonsillectomy: A Retrospective National Cohort Study of US Children. JAMA Otolaryngol Head Neck Surg 2023; 149:431-438. [PMID: 36995688 PMCID: PMC10064285 DOI: 10.1001/jamaoto.2023.0268] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 02/06/2023] [Indexed: 03/31/2023]
Abstract
Importance The American Academy of Otolaryngology-Head and Neck Surgery Foundation has recommended yearly surgeon self-monitoring of posttonsillectomy bleeding rates. However, the predicted distribution of rates to guide this monitoring remain unexplored. Objective To use a national cohort of children to estimate the probability of bleeding after pediatric tonsillectomy to guide surgeons in self-monitoring of this event. Design, Settings, and Participants This retrospective cohort study used data from the Pediatric Health Information System for all pediatric (<18 years old) patients who underwent tonsillectomy with or without adenoidectomy in a children's hospital in the US from January 1, 2016, through August 31, 2021, and were discharged home. Predicted probabilities of return visits for bleeding within 30 days were calculated to estimate quantiles for bleeding rates. A secondary analysis included logistic regression of bleeding risk by demographic characteristics and associated conditions. Data analyses were conducted from August 7, 2022 to January 28, 2023. Main Outcomes and Measures Revisits to the emergency department or hospital (inpatient/observation) for bleeding (primary/secondary diagnosis) within 30 days after index discharge after tonsillectomy. Results Of the 96 415 children (mean [SD] age, 5.3 [3.9] years; 41 284 [42.8%] female; 46 954 [48.7%] non-Hispanic White individuals) who had undergone tonsillectomy, 2100 (2.18%) returned to the emergency department or hospital with postoperative bleeding. The predicted 5th, 50th, and 95th quantiles for bleeding were 1.17%, 1.97%, and 4.75%, respectively. Variables associated with bleeding after tonsillectomy were Hispanic ethnicity (OR, 1.19; 99% CI, 1.01-1.40), very high residential Opportunity Index (OR, 1.28; 99% CI, 1.05-1.56), gastrointestinal disease (OR, 1.33; 99% CI, 1.01-1.77), obstructive sleep apnea (OR, 0.85; 99% CI, 0.75-0.96), obesity (OR,1.24; 99% CI, 1.04-1.48), and being more than 12 years old (OR, 2.48; 99% CI, 2.12-2.91). The adjusted 99th percentile for bleeding after tonsillectomy was approximately 6.39%. Conclusions and Relevance This retrospective national cohort study predicted 50th and 95th percentiles for posttonsillectomy bleeding of 1.97% and 4.75%. This probability model may be a useful tool for future quality initiatives and surgeons who are self-monitoring bleeding rates after pediatric tonsillectomy.

Abstract
OBJECTIVES To report a case of a morbidly obese 17-year-old boy who presented 4 days post-tonsillectomy with acute deep venous thromboses and a massive pulmonary embolism. To describe a protocol and decision-making tree for providing anticoagulation in the immediate post-tonsillectomy period. METHODS A chart review and review of the literature. RESULTS The patient ultimately did well and had no bleeding from the tonsil beds or further thromboembolic complications. A review of the literature revealed no available data regarding the safety of anticoagulation in the immediate post-tonsillectomy period. CONCLUSIONS We propose that if anticoagulation is needed within 14 days of tonsillectomy, submaximal anticoagulation with a reversible and titratable anticoagulant may be optimal. A multidisciplinary team approach is needed for these complex cases. Future reporting and investigation of anticoagulation post-tonsillectomy is needed.

Abstract
Background The main obstacle to a patient's recovery following a tonsillectomy is complications, and bleeding is the most frequent culprit. Predicting post-tonsillectomy hemorrhage (PTH) allows for accurate identification of high-risk populations and the implementation of protective measures. Our study aimed to investigate how well machine learning models predict the risk of PTH. Methods Data were obtained from 520 patients who underwent a tonsillectomy at The 940th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army. The age range of the patients was 2-57 years, and 364 (70%) were male. The prediction models were developed using five machine learning models: decision tree, support vector machine (SVM), extreme gradient boosting (XGBoost), random forest, and logistic regression. The performance of the models was evaluated using the area under the receiver operating characteristic curve (AUC). Shapley additive explanation (SHAP) was used to interpret the results of the best-performing model. Results The frequency of PTH was 11.54% among the 520 patients, with 10.71% in the training group and 13.46% in the validation set. Age, BMI, season, smoking, blood type, INR, combined secretory otitis media, combined adenoidectomy, surgical wound, and use of glucocorticoids were selected by mutual information (MI) method. The XGBoost model had best AUC (0.812) and Brier score (0.152). Decision curve analysis (DCA) showed that the model had a high clinical utility. The SHAP method revealed the top 10 variables of MI according to the importance ranking, and the average of the age was recognized as the most important predictor variable. Conclusion This study built a PTH risk prediction model using machine learning. The XGBoost model is a tool with potential to facilitate population management strategies for PTH.

Abstract
Objectives To examine the volume, topics, and reporting trends in the published literature of randomized clinical trials for pharmacologic pain management of pediatric tonsillectomy and adenotonsillectomy and to identify areas requiring further research. Data Sources PubMed (National Library of Medicine and National Institutes of Health), Scopus (Elsevier), CINAHL (EBSCO), and Cochrane Library (Wiley). Methods A systematic search of four databases was conducted. Only randomized controlled or comparison trials examining pain improvement with a pharmacologic intervention in pediatric tonsillectomy or adenotonsillectomy were included. Data collected included demographics, pain-related outcomes, sedation scores, nausea/vomiting, postoperative bleeding, types of drug comparisons, modes of administration, timing of administration, and identities of the investigated drugs. Results One hundred and eighty-nine studies were included for analysis. Most studies included validated pain scales, with the majority using visual-assisted scales (49.21%). Fewer studies examined pain beyond 24 h postoperation (24.87%), and few studies included a validated sedation scale (12.17%). Studies have compared several different dimensions of pharmacologic treatment, including different drugs, timing of administration, modes of administration, and dosages. Only 23 (12.17%) studies examined medications administered postoperatively, and only 29 (15.34%) studies examined oral medications. Acetaminophen only had four self-comparisons. Conclusion Our work provides the first scoping review of pain and pediatric tonsillectomy. With drug safety profiles considered, the literature does not have enough data to determine which treatment regimen provides superior pain control in pediatric tonsillectomy. Even common drugs like acetaminophen and ibuprofen require further research for optimizing the treatment of posttonsillectomy pain. The heterogeneity in study design and comparisons weakens the conclusions of potential systematic reviews and meta-analyses. Future directions include more noninferiority studies of unique comparisons and more studies examining oral medications given postoperatively.

Abstract
OBJECTIVES/HYPOTHESIS Post-tonsillectomy hemorrhage (PTH) is a potentially life-threatening complication. A recent meta-analysis suggests that ibuprofen may increase the risk of PTH. The aims of this study were to 1) re-evaluate the effect of ibuprofen on PTH given additional recent evidence and 2) to evaluate a potential dose effect of ibuprofen. STUDY DESIGN Meta-analysis and meta-regression; single-institution retrospective review. METHODS We conducted a systematic review of the literature and a meta-analysis of 12 studies comparing postoperative ibuprofen analgesia to non-nonsteroidal anti-inflammatory drug (NSAID) controls. Next, we performed a meta-regression analysis to assess for an effect of dose, if any, on rates of PTH. Five studies specifying a dose of 5 mg/kg (828 patients, 1,411 controls) and 7 studies using 10 mg/kg (5,633 patients, 7,656 controls) were included. We then conducted a novel single-institution, retrospective review of data for 1,046 patients prescribed intermediate-dose 7.5 mg/kg ibuprofen. RESULTS Ibuprofen was not associated with an increased rate of PTH (log odds ratio [OR], 0.21; 95% confidence interval [CI] -0.15, 0.57). Meta-regression showed that ibuprofen dose (5 and 10 mg/kg) did not have a statistically significant effect on PTH (OR, 1.32; 95% CI 0.30, 5.84). Uncontrolled, aggregate rates of PTH across all studies were 2.29% (N = 828) for 5 mg/kg and 4.65% (N = 5,633) for 10 mg/kg dosing. The rate of secondary hemorrhage in patients prescribed 7.5 mg/kg ibuprofen was 3.10% (N = 1,046). CONCLUSION We found no statistically significant increased risk of PTH when ibuprofen is prescribed at the low or high range of commonly used clinical dosages, compared to a non-ibuprofen regimen. Further studies with less heterogeneity are needed to determine if there is a clinically relevant dose-dependent difference in PTH with ibuprofen. LEVEL OF EVIDENCE 3 Laryngoscope, 2021.
