ABSTRACT
OBJECTIVE: Thoracic surgery is associated with one of the highest rates of chronic postsurgical pain (CPSP) among all surgical subtypes. Chronic postsurgical pain carries significant medical, psychological, and economic consequences, and further interventions are needed to prevent its development. This study aimed to determine the prevalence, characteristics, and risk factors associated with CPSP after thoracic surgery. DESIGN: A prospective cohort study. SETTING: Single-center tertiary care hospital. PARTICIPANTS: This study included 285 adult patients who underwent thoracic surgery at Toronto General Hospital in Toronto, Canada, between 2012 and 2020. MEASUREMENTS AND MAIN RESULTS: Demographic, psychological, and clinical data were collected perioperatively, and follow-up evaluations were administered at 3, 6, and 12 months after surgery to assess CPSP. Chronic postsurgical pain was reported in 32.4%, 25.4%, and 18.2% of patients at 3, 6, and 12 months postoperatively, respectively. Average CPSP pain intensity was rated to be 3.37 (SD 1.82) at 3 months. Features of neuropathic pain were present in 48.7% of patients with CPSP at 3 months and 71% at 1 year. Multivariate logistic regression models indicated that independent predictors for CPSP at 3 months were scores on the Hospital Anxiety and Depression Scale (adjusted odds ratio [aOR] of 1.07, 95% CI of 1.02 to 1.14, p = 0.012) and acute postoperative pain (aOR of 2.75, 95% CI of 1.19 to 6.36, p = 0.018). INTERVENTIONS: None. CONCLUSIONS: Approximately 1 in 3 patients will continue to have pain at 3 months after surgery, with a large proportion reporting neuropathic features. Risk factors for pain at 3 months may include preoperative anxiety and depression and acute postoperative pain.

PURPOSE: Hypotension after induction of general anesthesia is common and is associated with significant adverse events. Identification of patients at high risk can inform the use of preoperative mitigation strategies. We conducted a systematic review and meta-analysis to assess the diagnostic accuracy of the inferior vena cava collapsibility index (IVC-CI) and maximal diameter (dIVCmax) in predicting postinduction hypotension and to identify their predictive performance across different threshold ranges. METHODS: We searched MEDLINE, PubMed®, and Embase from inception to March 2023 for prospective observational studies exploring the performance of IVC-CI and dIVCmax in predicting postinduction hypotension in adults presenting for elective surgery under general anesthesia. We excluded studies reporting on IVC parameters predicting postinduction hypotension in the obstetric patient population or exclusively in patients with obesity. Trials screening and data extraction were conducted independently. We performed meta-analyses to identify the performance of IVC parameters in predicting postinduction hypotension, followed by subgroup analyses that sought the IVC-CI range with the highest hierarchical summary receiver-operating characteristic area under the curve (HSROC-AUC). We used a bivariate random effects model to calculate summary estimates. We evaluated study quality using Newcastle-Ottawa scores and certainty of evidence using the GRADE framework. RESULTS: We included 14 studies involving 1,166 patients. Pooled sensitivity and specificity of the IVC-CI to predict postinduction hypotension was 0.68 (95% confidence interval [CI], 0.55 to 0.79; coverage probability, 0.91) and 0.78 (95% CI, 0.69 to 0.85; coverage probability, 0.9), respectively, with an HSROC-AUC of 0.80 (95% CI, 0.68 to 0.85, high quality of evidence). An IVC-CI threshold range of 40-45% had an HSROC-AUC of 0.86 (95% CI, 0.69 to 0.93, high quality of evidence). CONCLUSIONS: Preoperative IVC-CI is a strong predictor of postinduction hypotension. We recommend that future studies use an IVC-CI threshold of 40-45% (low certainty of evidence). Future studies are needed to establish whether ultrasound-guided preoperative optimization improves outcomes in high-risk patients.

RéSUMé: OBJECTIF: L'hypotension après l'induction de l'anesthésie générale est fréquente et est associée à des effets indésirables importants. L'identification des patientâ¢es à haut risque peut éclairer l'utilisation de stratégies préopératoires d'atténuation. Nous avons réalisé une revue systématique et une méta-analyse pour évaluer la précision diagnostique de l'indice de collapsibilité de la veine cave inférieure (IC-VCI) et du diamètre maximal (dVCImax) pour prédire l'hypotension post-induction et identifier leurs performances prédictives dans différentes plages de seuils. MéTHODE: Nous avons fait des recherches dans les bases de données MEDLINE, PubMed® et Embase de leur création jusqu'en mars 2023 pour en extraire les études observationnelles prospectives explorant les performances de l'IC-VCI et du dVCImax pour la prédiction de l'hypotension post-induction chez des adultes se présentant pour une chirurgie non urgente sous anesthésie générale. Nous avons exclu les études rapportant des paramètres de VCI prédisant l'hypotension post-induction dans la population obstétricale ou exclusivement chez des personnes obèses. Le tri des études et l'extraction des données ont été menés indépendamment. Nous avons réalisé des méta-analyses pour identifier la performance des paramètres de VCI dans la prédiction de l'hypotension post-induction, suivies d'analyses de sous-groupes qui ont recherché la plage d'IC-VCI avec le plus haut niveau de hiérarchie de l'aire sous la courbe de la courbe ROC (HSROC-AUC). Nous avons utilisé un modèle bivarié à effets aléatoires pour calculer des estimations sommaires. Nous avons évalué la qualité des études à l'aide des scores de Newcastle-Ottawa et la certitude des données probantes à l'aide de l'outil GRADE. RéSULTATS: Quatorze études portant sur 1166 patient·es ont été incluses. La sensibilité et la spécificité combinées de l'IC-VCI pour prédire l'hypotension post-induction étaient de 0,68 (intervalle de confiance [IC] à 95 %, 0,55 à 0,79; probabilité de couverture, 0,91) et 0,78 (IC 95 %, 0,69 à 0,85; probabilité de couverture, 0,9), respectivement, avec une HSROC-AUC de 0,80 (IC 95 %, 0,68 à 0,85, données probantes de haute qualité). Une plage de seuils d'IC-VCI de 40 à 45 % avait une HSROC-AUC de 0,86 (IC 95 %, 0,69 à 0,93, haute qualité des données probantes). CONCLUSION: L'IC-VCI préopératoire est un bon prédicteur de l'hypotension post-induction. Nous recommandons que les études futures utilisent un seuil d'IC-VCI de 40 à 45 % (faible certitude des données probantes). De futures études sont nécessaires pour déterminer si l'optimisation préopératoire échoguidée améliore les devenirs chez la patientèle à risque élevé.

PURPOSE: Hypotension after induction of general anesthesia (GAIH) is common and is associated with postoperative complications including increased mortality. Collapsibility of the inferior vena cava (IVC) has good performance in predicting GAIH; however, there is limited evidence whether a preoperative fluid bolus in patients with a collapsible IVC can prevent this drop in blood pressure. METHODS: We conducted a single-centre randomized controlled trial with adult patients scheduled to undergo elective noncardiac surgery under general anesthesia (GA). Patients underwent a preoperative point-of-care ultrasound scan (POCUS) to identify those with a collapsible IVC (IVC collapsibility index ≥ 43%). Individuals with a collapsible IVC were randomized to receive a preoperative 500 mL fluid bolus or routine care (control group). Surgical and anesthesia teams were blinded to the results of the scan and group allocation. Hypotension after induction of GA was defined as the use of vasopressors/inotropes or a decrease in mean arterial pressure < 65 mm Hg or > 25% from baseline within 20 min of induction of GA. RESULTS: Forty patients (20 in each group) were included. The rate of hypotension after induction of GA was significantly reduced in those receiving preoperative fluids (9/20, 45% vs 17/20, 85%; relative risk, 0.53; 95% confidence interval, 0.32 to 0.89; P = 0.02). The mean (standard deviation) time to complete POCUS was 4 (2) min, and the duration of fluid bolus administration was 14 (5) min. Neither surgical delays nor adverse events occurred as a result of the study intervention. CONCLUSION: A preoperative fluid bolus in patients with a collapsible IVC reduced the incidence of GAIH without associated adverse effects.

RéSUMé: OBJECTIF: L'hypotension après induction de l'anesthésie générale (AG) est fréquente et est associée à des complications postopératoires, notamment à une augmentation de la mortalité. La collapsibilité de la veine cave inférieure (VCI) a été utilisée avec succès pour prédire la l'hypotension post-induction de l'AG; cependant, il existe peu de données probantes qu'un bolus liquidien préopératoire chez les patient·es présentant une collapsibilité de la VCI puisse prévenir cette baisse de la tension artérielle. MéTHODE: Nous avons réalisé une étude randomisée contrôlée monocentrique auprès de patient·es adultes devant bénéficier d'une chirurgie non cardiaque non urgente sous anesthésie générale. Les patient·es ont passé une échographie préopératoire ciblée (POCUS) pour identifier les personnes présentant une collapsibilité de la VCI (indice de collapsibilité de la VCI ≥ 43 %). Les personnes présentant une collapsibilité de la VCI ont été randomisées à recevoir un bolus de liquide préopératoire de 500 mL ou des soins de routine (groupe témoin). Les équipes chirurgicales et d'anesthésie ne connaissaient pas les résultats de l'examen ni l'attribution des groupes. L'hypotension après induction de l'AG a été définie comme l'utilisation de vasopresseurs/inotropes ou une diminution de la tension artérielle moyenne < 65 mm Hg ou > 25 % par rapport aux valeurs de base dans les 20 minutes suivant l'induction de l'AG. RéSULTATS: Quarante patient·es (20 dans chaque groupe) ont été inclus·es. Le taux d'hypotension après induction de l'AG était significativement réduit chez les personnes recevant des liquides préopératoires (9/20, 45 % vs 17/20, 85 %; risque relatif, 0,53; intervalle de confiance à 95 %, 0,32 à 0,89; P = 0,02). Le temps moyen (écart type) pour compléter l'échographie ciblée était de 4 (2) min, et la durée de l'administration du bolus liquidien était de 14 (5) min. Ni retards chirurgicaux ni effets indésirables ne sont survenus à la suite de l'intervention à l'étude. CONCLUSION: Un bolus liquidien préopératoire chez les patient·es présentant une collapsibilité de la VCI a réduit l'incidence d'hypotension après l'induction de l'anesthésie générale sans effets indésirables associés.

ABSTRACT
OBJECTIVES: As point-of-care ultrasound (POCUS) has emerged as a valuable tool for intussusception screening, this quality improvement study aimed to implement a "POCUS-first" pathway in a Pediatric Emergency Department (ED) to streamline workflow and expedite care for children with suspected intussusception. METHODS: This was a prospective analysis of children diagnosed with ileocolic intussusception in a Pediatric ED between June 2022 and June 2023. The study compared the "POCUS-first" cohort with the group receiving only radiology-performed ultrasound. Key outcomes included physician initial assessment to radiology-performed US time and physician initial assessment to reduction time. Continuous improvement efforts incorporated pediatric emergency medicine physician training, education, and pathway dissemination through plan-do-study-act cycles. RESULTS: The study included 29 patients in the "POCUS-first" pathway group and 70 patients in the non-POCUS group. The "POCUS-first" pathway demonstrated a significantly shorter physician initial assessment to reduction time compared to the non-POCUS group (170.7 min vs. 240.6 min, p = 0.02). Among non-transferred patients, the "POCUS-first" group also had a significantly shorter emergency department length of stay (386 min vs. 544 min, p = 0.047). CONCLUSIONS: Implementation of a "POCUS-first" pathway for managing ileocolic intussusception led to notable improvements in process efficiency. The shorter physician initial assessment to reduction time highlights the potential for expedited decision-making and intervention. These study findings support the potential of this pathway to optimize the management and outcomes of children with ileocolic intussusception.
RéSUMé: OBJECTIFS: Comme l'échographie au point de soin (POCUS) est devenue un outil précieux pour le dépistage de l'intussusception, cette étude d'amélioration de la qualité visait à mettre en Åuvre une voie "POCUS-first" dans un service d'urgence pédiatrique (ED) rationaliser le flux de travail et accélérer les soins aux enfants présentant une intussusception suspectée. MéTHODES: Il s'agissait d'une analyse prospective des enfants diagnostiqués avec une intussusception iléo-colique dans un DE pédiatrique entre juin 2022 et juin 2023. L'étude a comparé la cohorte "POCUS-first" avec le groupe recevant uniquement des ultrasons radiologiques. Les principaux résultats comprenaient l'évaluation initiale par le médecin du temps de radiologie effectué aux États-Unis et l'évaluation initiale par le médecin du temps de réduction. Les efforts d'amélioration continue ont incorporé la formation, l'éducation et la diffusion des parcours des médecins en médecine d'urgence pédiatrique par le biais de cycles de plan-do-study-act. RéSULTATS: L'étude a inclus 29 patients dans le groupe "POCUS-first" et 70 patients dans le groupe non-POCUS. La voie "POCUS-first" a démontré une évaluation initiale significativement plus courte du temps de réduction par rapport au groupe non POCUS (170,7 minutes vs. 240,6 minutes, p = 0,02). Parmi les patients non transférés, le groupe "POCUS-first" a également eu une durée de séjour à l'urgence significativement plus courte (386 minutes vs. 544 minutes, p = 0,047). CONCLUSIONS: La mise en Åuvre d'une voie "POCUS-first" pour gérer l'intussusception iléo-colique a conduit à des améliorations notables de l'efficacité des processus. L'évaluation initiale plus courte du médecin pour réduire le temps met en évidence la possibilité d'une prise de décision et d'une intervention accélérée. Les résultats de cette étude confirment le potentiel de cette voie pour optimiser la prise en charge et les résultats des enfants atteints d'intussusception iléo-colique.

OBJECTIVES: To provide a systematic review of the literature on the effects of peripheral magnetic stimulation (PMS) in the treatment of chronic peripheral neuropathic pain. METHODS: A systematic search of MEDLINE, EMBASE, CENTRAL, CINHAL, Web of Science, and ProQuest was conducted from inception to July 2023 to identify studies of any design published in English language that enrolled adult patients (≥18 years) that received PMS for treatment of a chronic peripheral neuropathic pain disorder (pain > 3 months). RESULTS: Twenty-three studies were identified which included 15 randomized controlled trials (RCTs), five case series, two case reports, and one non-randomized trial. PMS regimens varied across studies and ranged from 5 to 240 min per session over 1 day to 1 year of treatment. Results across included studies were mixed, with some studies suggesting benefits while others showing no significant differences. Of nine placebo-controlled RCTs, four reported statistically significant findings in favor of PMS use. In the meta-analysis, PMS significantly reduced pain scores compared to control within 0-1 month of use (mean difference -1.64 on a 0-10 numeric rating scale, 95% confidence interval -2.73 to -0.56, p = 0.003, I2 = 94%, 7 studies [264 participants], very low quality of evidence), but not at the 1-3 months and >3 months of PMS use (very low and low quality of evidence, respectively). Minimal to no adverse effects were reported with PMS use. DISCUSSION: There is limited and low-quality evidence to make definitive recommendations on PMS usage, however, the available data is encouraging, especially for short-term applications of this novel modality. Large high-quality randomized controlled trials are required to establish definitive efficacy and safety effects of PMS.

Point-of-care ultrasound (PoCUS) is used by health care professionals of various specialties worldwide, with excellent results demonstrating significant potential to advance patient care. However, in low resource areas of the world, where other imaging modalities are scarce and the potential of handheld pocket-sized PoCUS devices with great versatility and increasing affordability seems most significant, its use is far from being widespread. In this report, our group of Chadian, Israeli, and Canadian physicians with experience in rural, military, and conflict zone medical aid, discusses the barriers to the implementation of PoCUS in low resource areas and offers potential solutions.

Introduction: Postoperative urinary retention (POUR) frequently complicates the course of patients following hip and knee arthroplasty. Intrathecal morphine (ITM) was identified as a significant risk factor for POUR. The objective of this study was to investigate the incidence and risk factors for POUR in fast-track total joint arthroplasty (TJA) under spinal anaesthesia (SA) with ITM. Methods: We conducted a retrospective study of our institutional joint registry of patients who underwent primary TJA under SA with ITM between October 2017 and May 2021. Preoperative (baseline demographics) and perioperative data were collected. The primary outcome was the incidence of POUR after 8 h or earlier, either due to lack of voiding or according to patient's complaints of bladder distension. Univariate and adjusted analyses were performed to identify predictors of POUR. Results: Sixty-nine patients who underwent total knee arthroplasty (TKA) and 36 patients who underwent total hip arthroplasty (THA) under SA with ITM were included in the study. POUR requiring bladder catheterisation was diagnosed in 21% of patients. Independent predictors of POUR were age over 65 years and male gender. Conclusions: SA with ITM for TJA is associated with high rates of POUR in males older than 65 years of age. Other previously identified risk factors such as intraoperative fluid administration or comorbidities may not be as influential.
ABSTRACT
BACKGROUND: Chronic postsurgical pain is a common complication of surgery. The role of psychologic risk factors like depression and anxiety is substantially understudied in cardiac surgery. This study sought to identify perioperative factors associated with chronic pain at 3, 6, and 12 months after cardiac surgery. The authors hypothesize that baseline psychologic vulnerabilities have a negative influence on chronic postsurgical pain. METHODS: The authors prospectively collected demographic, psychologic, and perioperative factors in a cohort of 1,059 patients undergoing cardiac surgery at the Toronto General Hospital between 2012 and 2020. Patients were followed and completed chronic pain questionnaires at 3, 6, and 12 months after surgery. RESULTS: The study included 767 patients who completed at least one follow-up questionnaire. The incidence of postsurgical pain (more than 0 out of 10) at 3, 6, and 12 months after surgery was 191 of 663 (29%), 118 of 625 (19%), and 89 of 605 (15%), respectively. Notably, among patients reporting any pain, the incidence of pain compatible with a neuropathic phenotype increased from 56 of 166 (34%) at 3 months to 38 of 97 (39%) at 6 months and 43 of 67 (64%) at 12 months. Factors associated with postsurgical pain scores at 3 months include female sex, pre-existing chronic pain, previous cardiac surgery, preoperative depression, baseline pain catastrophizing scores, and moderate-to-severe acute pain (4 or more out of 10) within 5 postoperative days. CONCLUSIONS: Nearly one in three patients undergoing cardiac surgery reported pain at 3 months of follow-up, with approximately 15% reporting persistent pain at 1 yr. Female sex, pre-existing chronic pain, and baseline depression were associated with postsurgical pain scores across all three time periods.

General anesthesia is frequently administered during oocyte retrieval. Its effects on the outcomes of IVF cycles are uncertain. This study investigated whether administration of general anesthesia (specifically propofol) during oocyte retrieval affects IVF outcomes. A total of 245 women undergoing IVF cycles were included in this retrospective cohort study. IVF outcomes of 129 women who underwent oocyte retrieval under propofol anesthesia and 116 without anesthesia were compared. Data were adjusted for age, BMI, estradiol on triggering day and total gonadotropin dose. The primary outcomes were fertilization, pregnancy and live birth rates. A secondary outcome was the efficiency of follicle retrieval associated with the use of anesthesia. Fertilization rate was lower in retrievals under anesthesia compared to without (53.4% ± 34.8 vs. 63.7% ± 33.6, respectively; p = 0.02). There was no significant difference in the ratio of expected to retrieved oocytes between retrievals with and without anesthesia (0.8 ± 0.4 vs. 0.8 ± 0.8, respectively, p = 0.96). The differences in pregnancy and live birth rates between the groups were not statistically significant. General anesthesia administered during oocyte retrieval may have adverse effects on the fertilization potential of oocytes. This impact on the developmental potential of oocytes may lead to negative IVF outcomes and should be investigated further.

BACKGROUND: Thiamine is an essential co-factor for aerobic intracellular respiration, nerve conduction, and muscle contraction. Thiamine deficiency is common in the intensive care unit (ICU). Delirium is a frequent unwanted symptom among critical ill patients. Although the exact cause of ICU-associated delirium is unknown, abnormal nutrition and thiamine deficiency may contribute to the etiology. OBJECTIVES: To compare the prevalence of delirium among ICU patients who received thiamine with those who did not and to compare morbidity and mortality. METHODS: A retrospective study was conducted among ICU patients admitted 2014-2018. Routine thiamine administration began in 2016. Collected data included patient demographics, medical history, indication for ICU admission, hospital admission times, ventilation days, inotropic therapy, hemodialysis, tracheostomy, 28-day mortality, and need for anti-psychotic therapy. Group A received thiamine, group B did not. All data were statistically analyzed according to type. RESULTS: The study included 930 patients: 465 patients in group A and 465 in group B. At admission and throughout the hospitalization severity of disease parameters was worse in group A compared to group B, including acute physiology and chronic health evaluation (APACHE) score, admission lactate level, ventilation days, inotropic support, renal replacement therapy, tracheostomy, and ICU hospitalization. Group A had fewer delirium events without difference of maximal delirium score. No difference in mortality rate was observed. CONCLUSIONS: Thiamine administration was associated with lower delirium prevalence despite longer ICU admission times and higher disease severity parameters at admission and during ICU stay.

PURPOSE: Genitofemoral neuralgia (GFN) is a chronic pain condition that may be refractory to commonly employed treatment modalities. Implantation of a peripheral nerve stimulator (PNS) may provide significant pain relief; however, few reports have described placement of and response to a GFN PNS implant. CLINICAL FEATURES: We implanted a StimRouter® PNS in a 42-yr-old male with severe GFN that did not respond to pharmacologic and interventional pain management modalities and impaired all aspects of his function and quality of life. The often-challenging sonographic visualization of the genitofemoral nerve was aided by intraprocedural sensory mapping using a stimulating probe. Preoperatively, the patient's average pain was rated as 7 on a 0 to 10 numeric rating scale. Following the procedure, the patient experienced over 90% pain relief after one week. At one and five months post implantation, the patient's average pain scores were 1 and 0.5, respectively. The patient also reported substantial improvement in the physical component scores on the 12-Item Short Form Survey (SF-12), which remained similar at the five-month follow-up (from 26.1 preop to 57.2 at one month and 49.7 at five months). CONCLUSIONS: Peripheral nerve stimulator implantation may be a promising intervention when other analgesic modalities fail to manage refractory GFN. Further research to verify the effectiveness of this intervention and evaluate for appropriate integration in patient care is required.
RéSUMé: OBJECTIF: La névralgie génito-crurale (NGC) est une douleur chronique pouvant être réfractaire aux modalités de traitement couramment utilisées. L'implantation d'un stimulateur nerveux périphérique (SNP) peut apporter un soulagement significatif de la douleur. Cependant, peu de présentations de cas ont décrit la mise en place et la réponse à l'implantation d'un SNP pour soulager une névralgie génito-crurale. CARACTéRISTIQUES CLINIQUES: Nous avons implanté un SNP StimRouter® chez un homme de 42 ans atteint d'une NGC grave qui ne répondait pas aux modalités pharmacologiques et interventionnelles de prise en charge de la douleur et entravait tous les aspects fonctionnels et de qualité de vie. La visualisation échographique souvent difficile du nerf génito-crural a été facilitée grâce à une cartographie sensorielle intraprocédurale, réalisée à l'aide d'une sonde de stimulation. Avant la procédure, la douleur moyenne du patient a été évaluée à 7 sur une échelle d'évaluation numérique de 0 à 10. Suite à l'intervention, le patient a ressenti un soulagement de la douleur de plus de 90 % après une semaine. À un et à cinq mois suivant l'implantation, les scores moyens de douleur du patient étaient de 1 et 0,5, respectivement. Le patient a également rapporté une amélioration substantielle des scores de la composante physique du questionnaire SF-12, scores qui sont restés similaires au suivi à cinq mois (de 26,1 avant l'intervention à 57,2 à un mois et 49,7 à cinq mois). CONCLUSION: L'implantation d'un stimulateur nerveux périphérique pourrait être une intervention prometteuse lorsque d'autres modalités analgésiques ne parviennent pas à prendre en charge une névralgie génito-crurale réfractaire. D'autres recherches sont nécessaires pour vérifier l'efficacité de cette intervention et évaluer son intégration appropriée dans les soins aux patients.

STUDY OBJECTIVE: Adenotonsillectomy is the recommended treatment for children with obstructive sleep apnea (OSA). Since adenoidectomy alone may be associated with significantly lower morbidity, mortality, and cost, we aimed to investigate whether adenoidectomy alone is a reasonable and appropriate treatment for children with OSA. METHODS: Five-hundred fifteen consecutive children diagnosed with moderate-to-severe OSA (apnea-hypopnea index > 5) based on polysomnography and who underwent adenoidectomy or adenotonsillectomy were reevaluated after 17-73 months (mean 41) for residual or recurrent OSA using a validated questionnaire (Pediatric Sleep Questionnaire, PSQ). Failure of OSA resolution was defined as a positive mean PSQ score ≥ 0.33. Contribution of age, obesity, tonsil size, and OSA severity at baseline to adenoidectomy or adenotonsillectomy failure was examined. RESULTS: Positive PSQ score occurred in 15% of the entire sample and was not influenced by age or gender. No difference in failure rate was observed between adenoidectomy and adenotonsillectomy for children who were not obese with apnea-hypopnea index < 10 and had small tonsils (< 3). Children with apnea-hypopnea index ≥ 10 and/or tonsil size ≥ 3 showed a higher failure rate after adenoidectomy compared to adenotonsillectomy (20% versus 9.8%, p = 0.028). CONCLUSIONS: We suggest that subjective, long term outcomes of adenoidectomy are comparable to those of adenotonsillectomy in non-obese children under 7 years old with moderately OSA and small tonsils. Hence, adenoidectomy alone is a reasonable option in some children. Future prospective randomized studies are warranted to define children who may benefit from adenoidectomy alone and those children in whom adenoidectomy alone is unlikely to succeed.
