Management of Persistent, Post-adenotonsillectomy Obstructive Sleep Apnea in Children: An Official American Thoracic Society Clinical Practice Guideline.

Background: Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder. Although adenotonsillectomy is first-line management for pediatric OSA, up to 40% of children may have persistent OSA. This document provides an evidence-based clinical practice guideline on the management of children with persistent OSA. The target audience is clinicians, including physicians, dentists, and allied health professionals, caring for children with OSA. Methods: A multidisciplinary international panel of experts was convened to determine key unanswered questions regarding the management of persistent pediatric OSA. We conducted a systematic review of the relevant literature. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to rate the quality of evidence and the strength of the clinical recommendations. The panel members considered the strength of each recommendation and evaluated the benefits and risks of applying the intervention. In formulating the recommendations, the panel considered patient and caregiver values, the cost of care, and feasibility. Results: Recommendations were developed for six management options for persistent OSA. Conclusions: The panel developed recommendations for the management of persistent pediatric OSA based on limited evidence and expert opinion. Important areas for future research were identified for each recommendation.

Obstructive sleep apnea affects the psychological and behavioural development of children-a case-control study.

This study aims to investigate the effects of obstructive sleep apnea on paediatric psychological and behavioural abnormalities. A total of 1086 paediatric patients with obstructive sleep apnea and 728 sample snoring controls were enrolled in the study. Patients with obstructive sleep apnea underwent bilateral tonsillectomy plus adenoidectomy or adenoidectomy alone. Repeated Autism Behaviour Checklist, Spence Children's Anxiety Scale, and Children's Depression Inventory were performed to assess the autism symptoms, anxiety level and depressive symptoms before and after surgery. The score of Autism Behaviour Checklist in preschool children with obstructive sleep apnea was higher than that in control. In school children with obstructive sleep apnea, the score of Spence Children's Anxiety Scale was also higher. School children with obstructive sleep apnea with depressive symptoms were significantly higher than that in control. The scores of Autism Behaviour Checklist, Spence Children's Anxiety Scale, and Children's Depression Inventory in the obstructive sleep apnea group after surgery were significantly lower than that before surgery. Our study showed that the score of Spence Children's Anxiety Scale and Children's Depression Inventory had a close correlation with the illness course and hypoxia duration. The Spence Children's Anxiety Scale and Children's Depression Inventory scores are also closely associated with the Autism Behaviour Checklist score. These results suggest that obstructive sleep apnea may have a significant impact on autism symptoms, anxiety levels and depressive symptoms in children. We found that the longer the duration of the obstructive sleep apnea course and hypoxia, the greater the impact on anxiety level and depressive symptoms. The suspected autism symptoms, anxiety level and depressive symptoms in children with obstructive sleep apnea were also significantly correlated. Thus, early detection and timely treatment may often reverse the psychological and behavioural abnormalities caused by obstructive sleep apnea.

The role of adenoid immune phenotype in polysensitized children with allergic rhinitis and adenoid hypertrophy.

BACKGROUND: There is increasing interest in elucidating the relationship between adenoid hypertrophy (AH) and allergic rhinitis (AR). However, the impact of aeroallergen sensitization patterns on children with AH and AR remains unclear. METHODS: Patients aged 2-8 years (recruited from January 2019 to December 2022) with nasal symptoms were assessed for allergies, adenoid size, and respiratory viral infection history. The serum total immunoglobulin E (IgE) and specific IgE levels were measured, and flexible nasal endoscopy was performed. The relationship between AH, aeroallergen sensitization patterns, and lymphocyte subpopulations in adenoid samples was analyzed using flow cytometry. RESULTS: In total, 5281 children were enrolled (56.5% with AR; and 48.6% with AH). AH was more prevalent in children with AR. Compared to nonsensitized individuals, those polysensitized to molds had a higher prevalence of AH (adjusted OR 1.61, 95% CI 1.32-1.96) and a greater occurrence of two or more respiratory viral infections, particularly in adenoidectomy patients. The percentages and corrected absolute counts of regulatory T (Treg) cells, activated Tregs, class-switched memory B cells (CSMBs), natural killer (NK) T cells, and NK cell subpopulations were reduced in the adenoid tissues of children with both AH and AR (AH-AR) compared to AH-nAR children. Polysensitization in AH-AR children correlated with lower CSMB percentages. CONCLUSION: Polysensitivity to molds is associated with an increased risk of AH in children with AR. Fewer B cells, NK cells, and Treg cells with an effector/memory phenotype were detected in the adenoids of AR children, and these lower percentages of immune cells, particularly CSMBs, were closely linked to aeroallergen sensitization models and respiratory viral infection.

Positive end-expiratory pressure in chronic care of children with obstructive sleep apnoea.

Positive end-expiratory pressure (PEEP) consists of the delivery of a constant positive pressure in the airways by means of a noninvasive interface aiming to maintain airway patency throughout the entire respiratory cycle. PEEP is increasingly used in the chronic care of children with anatomical or functional abnormalities of the upper airways to correct severe persistent obstructive sleep apnea despite optimal management which commonly includes adenotonsillectomy in young children. PEEP may be used at any age, due to improvements in equipment and interfaces. Criteria for CPAP/NIV initiation, optimal setting, follow-up and monitoring, as well as weaning criteria have been established by international experts, but validated criteria are lacking. As chronic PEEP is a highly specialised treatment, patients should be managed by an expert pediatric multidisciplinary team.

Measuring immediate surgical success in children undergoing adenotonsillectomy.

Adenotonsillectomy is the most common indication for sleep-disordered breathing in children. Measuring pharyngeal closing pressures in anaesthetised children allows identification of severe obstructive sleep apnoea. This technique could help quantify immediate surgical impact and risk stratify postoperative treatment in these patients.

Bispectral Index versus the University of Michigan Sedation Scale in assessing sedation depth during pediatric drug-induced sleep endoscopy.

BACKGROUND AND PURPOSE: Bispectral Index (BIS) and University of Michigan Sedation Scale (UMSS) were two commonly used methods of monitoring the sedation depth, but their correlation was not clear. The purpose of this study is to ascertain if BIS correlates with UMSS in determining the sedation level during pediatric drug-induced sleep endoscopy (DISE). METHODS: One-hundred children, aged 36-143 months, with ASA I~II grade, were enrolled. They were subject to general anesthesia for an elective adenotonsillectomy. Two drug regimens were used. After UMSS ≥ 3, the sites of airway obstructions were located by checking the supraglottic airway structures with a fibrous laryngoscope. UMSS scores, BIS values, electromyography (EMG), and signal quality indices (SQIs) were recorded at the pre-medication and pre-DISE baseline (T0), 5 min subsequent to medication administration but prior to DISE initiation (T1), 1 min after DISE was initiated (T2), 1 min after DISE was completed (T3), 1 min subsequent to tracheal intubation (T4), 1 min following extubation (T5), and 30 min past extubation (T6). RESULTS: There were strong correlations between BIS monitor readings and UMSS scores for total and two regimens. Kappa values revealed moderate agreement between BIS and UMSS for total and two regimens. The agreement rates were 67.47% for the total, 61.43% for Regimen 1, and 73.42% for Regimen 2, respectively. CONCLUSION: BIS correlates with UMSS in determining the sedation level during pediatric DISE for two regimens. BIS might serve as an appropriate indicator of sedation intensity when UMSS could not be used.

Is there an OAHI or O2 nadir that predicts the need for preoperative echocardiogram prior to adenotonsillectomy for children with severe obstructive sleep apnea?

PURPOSE: To investigate threshold values for obstructive apnea-hypopnea index (OAHI) and nadir oxygen saturation (NspO2) in children with severe obstructive sleep apnea (OSA) to identify children most appropriate for preoperative echocardiography. METHODS: A multi-institutional retrospective chart review was performed on children who underwent echocardiography and polysomnogram within a year. Children with severe OSA as defined by OAHI > 10 or NspO2 < 80% were included. Receiver operator curves and Youden's J index were used to assess the discriminatory ability and threshold values of OAHI and NspO2 for right heart strain (RHS) on echocardiography. RESULTS: A total of 173 prepubertal (< 10 years) children and 71 postpubertal (≥ 10 years) children of age were included. RHS was seen in 9 (5%) prepubertal children and 4 (6%) postpubertal children. In prepubertal children, OAHI and NspO2 were poor predictors of RHS (area under the curve [AUC] 0.53 [95%CI 0.45-0.61], p = 0.748; AUC 0.56 [95%CI 0.48-0.64], p = 0.609). In postpubertal children, threshold values of 55 events/hour and 69% were strong predictors for RHS (AUC 0.88 [95%CI 0.78-0.95], p < 0.001; AUC 0.92 [95%CI 0.83-0.97], p < 0.001). CONCLUSION: In children with severe OSA, evidence of RHS is low. Postpubertal children with OAHI > 55 and NspO2 < 69% appear most appropriate for echocardiography. Clinicians should weigh the risks and benefits of preoperative echocardiography for each child with these threshold values in mind.

Metabolomic profiling of pediatric post-tonsillectomy pain: A proof-of-concept study.

INTRODUCTION: Tonsillectomies are among the most common surgical procedures in children, with over 500 000 cases annually in the United States. Despite universal administration of intraoperative opioid analgesia, three out of five children undergoing tonsillectomy report moderate-to-severe pain upon recovering from anesthesia. The underlying molecular mechanisms of post-tonsillectomy pain are not well understood, limiting the development of targeted treatment strategies. Our study aimed to identify candidate serum metabolites associated with varying severity of post-tonsillectomy pain. METHODS: Venous blood samples and pain scores were obtained from 34 children undergoing tonsillectomy ± adenoidectomy, and metabolomic analysis was performed. Supervised orthogonal projections to latent structures discriminant analysis were employed to identify differentially expressed metabolites between children with severe and mild pain, as well as between moderate and mild pain. RESULTS: Pain scores differentiated children as mild (n = 6), moderate (n = 14), or severe (n = 14). Four metabolites (fatty acid 18:0(OH), thyroxine, phosphatidylcholine 38:5, and branched fatty acids C27H54O3) were identified as candidate biomarkers that differentiated severe vs. mild post-tonsillectomy pain, the combination of which yielded an AUC of 0.91. Similarly, four metabolites (sebacic acid, dicarboxylic acids C18H34O4, hydroxy fatty acids C18H34O3, and myristoleic acid) were identified as candidate biomarkers that differentiated moderate vs. mild post-tonsillectomy pain, with AUC values ranging from 0.85 to 0.95. CONCLUSION: This study identified novel candidate biomarker panels that effectively differentiated varying severity of post-tonsillectomy pain. Further research is needed to validate these data and to explore their clinical implications for personalized pain management in children undergoing painful surgeries.

Does resident involvement in tonsillectomy affect outcomes?

OBJECTIVE: Tonsillectomy is essentially a solo surgery with a well-described complication profile. It may serve as a good benchmark to evaluate the resident-as-surgeon. This study examined complications such as post-tonsillectomy bleeding in children undergoing tonsillectomy by attending surgeons (AS) or pediatric otolaryngologist-supervised residents. METHODS: Charts were reviewed of all children aged 12 and under who had tonsillectomy +/- adenoidectomy at a children's hospital between Jan 2019 and Dec 2020. Patient age, gender, BMI, indication for surgery, surgical technique, presence of a resident surgeon, primary bleeding, secondary bleeding, treatment of bleeding, other Emergency Room (ER) visits, and clinic phone calls were recorded. Binary logistic regression was performed. RESULTS: 2051 total children (1092 (53.2 %) males and 956 (46.6 %) females) with a mean age of 6.1 years (95 % CI 6.0-6.2) were included. 1910 (93.0 %) underwent surgery for tonsillar obstruction. 1557 (75.9 %) underwent monopolar cautery tonsillectomy. 661 (32.2 %) had a resident surgeon. 274 (13.4 %) had a related ER visit within 15 days. 18 (0.9 %) had a primary bleed and 155 (7.6 %) had a secondary bleed. Binary logistic regression showed that significant predictors of postoperative ER visits were patient age (OR = 1.101, 95 % CI = 1.050-1.154, p < .001) and resident involvement (OR = 0.585, 95 % CI = 0.429-,797, p < .001). Only age was associated with overall postoperative bleeding incidence (OR = 1.131, 95 % CI = 1.068-1.197, p < .001), as well as secondary bleeding (OR = 1.128, 95 % CI = 1.063-1.197, p < .001). There were no significant predictors of primary bleeding. CONCLUSION: Resident involvement in pediatric tonsillectomy is associated with decreased postoperative ER utilization and does not appear to increase common postoperative complications including bleeding and dehydration.

Long-term efficacy of balloon dilation of the pediatric Eustachian tube: A six-year matched cohort study.

PURPOSE: Balloon dilation of the Eustachian tube (BDET) has not been evaluated extensively in children outside of retrospective case series. The purpose of this study is to report the long-term safety and efficacy of this procedure in children with matched controls. MATERIALS AND METHODS: This is a two-center retrospective matched cohort study. Children having undergone tympanostomy tube (TT) placement and adenoidectomy with recurrence of symptoms underwent BDET at an academic affiliated multi-specialty practice. Comparison was made with children receiving TT at a tertiary medical center, matching for number of prior TT, prior adenoidectomy, age, and sex. Outcome measures were risk of failure and the need for additional surgery. Kaplan-Meier survival plots were used to compare risk of failure. RESULTS: Thirty-three Eustachian tubes were dilated in 20 patients, aged 14 months-14 years. All patients had previously undergone TT insertion and adenoidectomy. Patients undergoing BDET had normal post-operative tympanograms in 80 % of cases. Mean follow up was 6.7 years with 2 patients failing in the BDET group and 8 in the TT insertion group. Dilated patients had a significantly lower risk of failure than those who underwent TT insertion (adjusted HR: 0.18; 95 % CI: 0.04, 0.81; p = 0.03). The probability of being failure free at six years was 88 % (95 % CI: 71, 95 %) in the BDET cohort and 53 % (95 % CI: 33, 70 %) in the TT insertion cohort. There were no complications. CONCLUSIONS: BDET appears to be safe and possibly superior to TT placement in children with refractory Eustachian tube dysfunction. LEVEL OF EVIDENCE: 2b.

Effectiveness of bismuth subgallate for preventing bleeding following adenotonsillectomy: A multicentre study.

BACKGROUND: Tonsillectomy and adenotonsillectomy are surgical procedures routinely performed worldwide, with various complications, including postoperative bleeding (PTH). Among haemostatic agents, bismuth subgallate (BS) has been employed in the past decades, but its use is controversial in children. OBJECTIVE: This retrospective, multicentre study aims to evaluate the effectiveness and safety of BS in preventing PTH following tonsillectomy and adenotonsillectomy. MATERIALS AND METHODS: Two cohorts of children between 0 and 18 years of age were compared in two different hospitals. The first (active) group of patients included children who underwent tonsillectomy/adenotonsillectomy performed using BS added to gauze swabs, whereas this agent was not administered to the second (control) group. The following variables were analysed: age, gender, degree of tonsillar hyperplasia, length of hospital stay, acute complications (including bleeding and infection), further admissions to the Paediatric Emergency Department (PED), and further hospital admissions in the 30 days postoperatively. RESULTS: Four-thousand- seven hundred forty-four children were included in the study, 2598 in the active group and 2146 in the control group. The cases included in the active treatment group displayed a significantly reduced PTH prevalence, 1.4 versus 2.6 % (p < 0.05). No cases of neurological complications or aspiration pneumonia were detected. CONCLUSIONS: This study supports BS as a safe and reliable option for preventing severe PTH following tonsillectomy/adenotonsillectomy.

Artificial intelligence and ChatGPT: An otolaryngology patient's ally or foe?

BACKGROUND: As artificial intelligence (AI) is integrating into the healthcare sphere, there is a need to evaluate its effectiveness in the various subspecialties of medicine, including otolaryngology. Our study intends to provide a cursory review of ChatGPT's diagnostic capability, ability to convey pathophysiology in simple terms, accuracy in providing management recommendations, and appropriateness in follow up and post-operative recommendations in common otolaryngologic conditions. METHODS: Adenotonsillectomy (T&A), tympanoplasty (TP), endoscopic sinus surgery (ESS), parotidectomy (PT), and total laryngectomy (TL) were substituted for the word procedure in the following five questions and input into ChatGPT version 3.5: "How do I know if I need (procedure)," "What are treatment alternatives to (procedure)," "What are the risks of (procedure)," "How is a (procedure) performed," and "What is the recovery process for (procedure)?" Two independent study members analyzed the output and discrepancies were reviewed, discussed, and reconciled between study members. RESULTS: In terms of management recommendations, ChatGPT was able to give generalized statements of evaluation, need for intervention, and the basics of the procedure without major aberrant errors or risks of safety. ChatGPT was successful in providing appropriate treatment alternatives in all procedures tested. When queried for methodology, risks, and procedural steps, ChatGPT lacked precision in the description of procedural steps, missed key surgical details, and did not accurately provide all major risks of each procedure. In terms of the recovery process, ChatGPT showed promise in T&A, TP, ESS, and PT but struggled in the complexity of TL, stating the patient could speak immediately after surgery without speech therapy. CONCLUSIONS: ChatGPT accurately demonstrated the need for intervention, management recommendations, and treatment alternatives in common ENT procedures. However, ChatGPT was not able to replace an otolaryngologist's clinical reasoning necessary to discuss procedural methodology, risks, and the recovery process in complex procedures. As AI becomes further integrated into healthcare, there is a need to continue to explore its indications, evaluate its limits, and refine its use to the otolaryngologist's advantage.

Different techniques of adenoidectomy and its impact on middle ear pressure: a randomized controlled study.

OBJECTIVES: The aim of this work is to compare between different techniques of adenoidectomy: endoscopic microdebrider-assisted, coblation and conventional adenoidectomy and its effect on middle ear pressure. BACKGROUND: Adenoidectomy, either alone or with tonsillectomy, is considered among the most performed procedures in pediatric otorhinolaryngology. This procedure usually related to the Eustachian tube function and middle ear status. Eustachian tube dysfunction is mainly caused by mechanical obstruction of the tubal orifice, insufficient swallowing and inflammation in the nasopharyngeal mucosa. METHODS: This prospective randomized study was conducted on 90 patients with symptomatic adenoid hypertrophy confirmed by nasopharyngeal X-ray and endoscopic grading preoperatively. Patients were admitted at Otorhinolaryngology department of our institute during the period from January 2022 to January 2023. They were divided into three groups that were operated either by conventional (Group I), endoscopic microdebrider (Group II), or coblation technique (Group III). Each group was assessed through the audiometric parameters plus postoperative bleeding, and VAS results for pain score and postoperative endoscopic grading for adenoid recurrence. RESULTS: Mean age in group A was 9.03 years and in group B was 8.99 years and was 8.99 years in group C with insignificant differences between three groups. There is significant improvement of tympanographic results comparing all groups of the patients at 6 months postoperatively. There is significant relation between the mean VAS comparing preoperative and postoperative results. CONCLUSION: There are better results in tympanographic data at conventional adenoidectomy versus other techniques. However, there are also better postoperative results after either coblation or endoscopic microdebrider adenoidectomy over the conventional technique.

Maximal medical treatment of adenoid hypertrophy: a prospective study of preschool children.

PURPOSE: This study aimed to examine the effectiveness of the combined maximal medical treatment for adenoid hypertrophy in preschool children. METHODS: Sixty-four children underwent one-year combined therapy with intranasal mometasone furoate, oral desloratadine, nasal saline irrigation, and bacteriotherapy. Additionally, decongestion drops were applied during scheduled breaks. RESULTS: Of the 64 treated children, 72% showed clinical improvement in adenoid symptoms while 28% did not improve and underwent surgery. These groups differed significantly in terms of the overall reduction in ailments after treatment (p < 0.001), infection rate (p < 0.001), catarrh severity (p < 0.001) and nasal patency (p < 0.001). Endoscopic examination confirmed that responders experienced, on average, a decrease of 8.4% in the adenoid/choana ratio and an improvement in mucosal coverage of the adenoid. These effects were not observed in the group of children whose parents opted for surgery after nine months of conservative treatment. CONCLUSIONS: The proposed new schema of long-term maximal medical treatment with the use of combined intermittent treatment of intranasal mometasone furoate and decongestion drops, oral desloratadine, nasal saline irrigation, and bacteriotherapy can be attempted in patients with adenoid hypertrophy symptoms, and responders may avoid the need for surgery. The applied treatment breaks resulted in a low number of therapeutic side effects.

Comparison of classical, coblation, and combined adenoidectomy techniques in paediatric patients: a single-blind, prospective study.

BACKGROUND AND OBJECTIVES: Adenoidectomy is one of the most commonly performed surgeries in pediatric otolaryngological practice. This prospective study compared three different adenoidectomy techniques' intra-operative and postoperative outcomes in pediatric patients. The techniques evaluated were classical (blind curettage), coblation, and a combined approach. MATERIALS AND METHODS: Ninety pediatric patients undergoing adenoidectomy were enrolled in the study. The patients were divided into three groups based on the technique used: Group A, classical adenoidectomy (blind curettage); Group B, coblation adenoidectomy and Group C, combined (blind curettage + coblation) adenoidectomy. The intra-operative time, degree of bleeding, and complications during and after the operations were recorded. RESULTS: Group A had a significantly shorter operative time than the other groups. However, there was no significant difference in the mean operative time between Groups B and C. The mean amount of intra-operative bleeding differed significantly among the groups. Group B had significantly less bleeding than Group A or Group C. The amount of bleeding also differed significantly between Groups A and C. The postoperative pain scores did not differ significantly among the groups. While complications were infrequent in all groups, Group C did not exhibit a higher complication rate than Groups A and B. The absence of residual or recurrent adenoid tissue in any of the groups during long-term follow-up examinations highlights the effectiveness of all three adenoidectomy techniques in preventing adenoid regrowth. CONCLUSIONS: The combined approach, which was one of the techniques studied, demonstrated an intermediate profile in terms of operative time and intra-operative bleeding compared to the classical and coblation techniques. These findings suggest that this combined approach may be a feasible option for adenoidectomy in pediatric patients, considering its similar low incidence of postoperative complications.

Central and mixed apneas in children with obstructive sleep apnea: effect of adenotonsillectomy.

PURPOSE: Investigate the effect of adenotonsillectomy on mixed apnea index (MAI) and central apnea index (CAI) in children with moderate-to-severe obstructive sleep apnea syndrome (OSAS). METHODS: Observational retrospective analysis of polysomnographic data in children diagnosed with moderate-to-severe OSAS and without comorbidity, submitted to adenotonsillectomy. RESULTS: Data were available for 80 children, 55 boys and 25 girls, with a median age of 3.6 years (2.1-5.9). Before surgery AHI was 14.1 (11.0-18.4) per hour, with a median preoperative OAI of 7.1 (4.1-10.6), MAI of 1.2 (0.6-1.6) and CAI of 1.0 (0.4-2.0). Adenotonsillectomy caused significant improvements in MAI, from 1.2 (0.6-1.6) to 0.5 (0.1-0.8) (p < 0.001) and CAI from 1.0 (0.4-2.0) to 0.5 (0.1-0.9) (p < 0.001). This represents a normalization of MAI in 91.7% and CAI in 75.6% of children that had an abnormal value prior surgery. CONCLUSION: Non obstructive apneas are common in children with OSAS. Adenotonsillectomy caused significant decrease not only in OAI, but also in MAI and CAI in children with moderate-to-severe OSAS.

Pediatric chronic rhinosinusitis.

PURPOSE: An up-to-date overview of diagnosis, differential diagnosis, comorbidities, and current medical and surgical management of pediatric chronic rhinosinusitis (PCRS). METHODS: Review of current evidence-based literature on PCRS. RESULTS: Diagnosis of PCRS seems to be improving based on recent evidence using nasal endoscopy as well as computed tomography scanning. Recent literature supports the fact that chronic adenoiditis can be an independent etiology of symptoms of chronic sinusitis, that are very similar to chronic adenoiditis. Allergic rhinitis and immune deficiency play important roles in the management of PCRS. Surgery for PCRS has evolved significantly in the last 15-20 years to include adenoidectomy as well as endoscopic sinus surgery. CONCLUSIONS: PCRS is very common in children causing poor QOL for these children. Medical management remains the main stay of treatment with attention to management of co-morbidities that may contribute to the disease severity. Making the correct diagnosis will help with the choice of surgical intervention if medical management fails.

The efficacy of perioperative antibiotic therapy in adenotonsillectomy children.

PURPOSE: To evaluate the role of perioperative antibiotics use in children after adenotonsillectomy. METHODS: SPSS 27.0 was used for statistical analysis. Two independent samples mean T test was used to evaluate the throat pain scores consecutive 3 days after the surgery, the time to resume to normal diet, and the wound healing time. Logistic regression analysis was used to evaluate the independent risk factors of the two groups. The generalized estimation model was used to evaluate the correlation between age and postoperative pain scores, and the relationship between different tonsillar bed gradings and postoperative pain scores. RESULTS: The pain scores were 5.83 ± 1.879, 5.20 ± 1.933, and 4.02 ± 1.936 in the observation group; and 6.83 ± 1.892, 6.17 ± 2.001, and 5.29 ± 2.068 in the control group on days 1-3 after surgery, respectively. The time of pain disappearance was 6.24 ± 2.121 days in the observation group and 7.73 ± 2.210 days in the control group. The wound repair time was 18.66 ± 2.200 days in the observation group and 18.70 ± 2.468 days in the control group. Logistic regression analysis showed that fever was an independent risk factor for the two groups and was negatively correlated (B = - 1.237, P < 0.001, OR = 0.290). Generalized estimation model showed that there was a positive correlation between age and pain scores (P < 0.001), and with the increasing grading of tonsillar bed, the higher the pain scores was (P < 0.001). CONCLUSIONS: Perioperative use of antibiotics in children with adenotonsillectomy can effectively reduce postoperative fever, throat pain symptoms, and shorten the pain time. With the increasing of tonsillar bed grading, perioperative antibiotic therapy was more necessary.

Diagnosis of Fever Source Following Tonsillectomy and Adenoidectomy in the Pediatric Emergency Department.

OBJECTIVES: This study aimed to describe the epidemiology and diagnoses of children with postoperative fever (a temperature of 38°C or higher) during the week after tonsillectomy and/or adenoidectomy and to assess the yield of the laboratory tests and otolaryngologist consultations of these patients in the pediatric emergency department (ED). METHODS: We conducted a retrospective cohort study that included all children who presented with fever to the pediatric ED of a tertiary university-affiliated medical center between May 2017 and April 2020 during the week after a tonsillectomy and/or adenoidectomy. RESULTS: There were 94 patients who fulfilled study entry criteria during the 3-year study period, representing a 6% rate of postoperative fever for combined tonsillectomy and adenoidectomy and 3% for adenoidectomy alone. Only 9 patients (<10% of the total) were classified as having bacterial infection, whereas the most common cause for the fever was pneumonia diagnosed by chest radiography. None had surgical site infection. There was no significant difference in blood test findings of patients diagnosed with a bacterial infection and patients with a presumed viral infection or an inflammatory response to surgery. CONCLUSIONS: The results of this investigation revealed that the source of fever of the overwhelming majority of children who were referred to the pediatric ED for fever after undergoing tonsillectomy and/or adenoidectomy was pneumonia as determined by chest radiography, which can be performed in an outpatient setting. Blood tests and otolaryngologist consultations were not contributory in classifying the source of fever, questioning the value of their routine use in these patients.

Change in Pediatric Adenotonsillectomy Postoperative Visit Patterns After Opioid Food and Drug Administration Warning.

STUDY OBJECTIVE: This study aimed to determine the association between opioid prescriptions given after tonsillectomy with adenoidectomy (T + A) and pain-related return visit rates in pediatric patients. Determine association between Food and Drug Administration (FDA) black box warning against opioid use in this population and pain-related return visit rates. METHODS: This was a single-institution retrospective cohort study of pediatric patients who underwent T + A between April 2012 and December 2015 and had return visits to the emergency department or urgent care center. Data were obtained from the hospital electronic warehouse using International Classification of Diseases-9/10 procedure codes. Odds ratios (ORs) with 95% confidence intervals (CIs) for return visits were calculated. Multivariate logistic regression analysis was used to measure association between opioid prescriptions and return visit rates as well as FDA warning and return visit rates adjusting for confounders. RESULTS: There were 4778 patients who underwent T + A, median age, 5 years. Of these, 752 (15.7%) had return visits. Pain-related return visits were higher in patients who received opioid prescriptions (adjusted OR, 1.31; 95% CI, 1.09-1.57). After FDA warning, opioids were prescribed at a lower rate (47.9%) compared with previous (98.6%) (OR, 0.01; 95% CI, 0.008-0.02). Pain-related return visits were lower after FDA warning (OR, 0.73; 95% CI, 0.61-0.87). Steroid prescription rate increased after FDA warning (OR, 415; 95% CI, 197-874). CONCLUSIONS: Opioid prescriptions were associated with higher pain-related return visits after T + A, whereas issuance of FDA black box warning against codeine use was associated with lower pain-related return visits. Our data suggest that the black box warning potentially had unintended benefits in pain management and health care usage.
