Contamination of equipment and surfaces in the operating room anesthesia workspace: a cross-sectional study

ABSTRACT BACKGROUND: Contamination of the breathing circuit and medication preparation surface of an anesthesia machine can increase the risk of cross-infection. OBJECTIVE: To evaluate the contamination of the anesthetic medication preparation surface, respiratory circuits, and devices used in general anesthesia with assisted mechanical ventilation. DESIGN AND SETTING: Cross-sectional, quantitative study conducted at the surgical center of a philanthropic hospital, of medium complexity located in the municipality of Três Lagoas, in the eastern region of the State of Mato Grosso do Sul. METHODS: Eighty-two microbiological samples were collected from the breathing circuits. After repeating the samples in different culture media, 328 analyses were performed. RESULTS: A higher occurrence of E. coli, Enterobacter spp., Pseudomonas spp., Staphylococcus aureus, and Streptococcus pneumoniae (P < 0.001) were observed. Variations were observed depending on the culture medium and sample collection site. CONCLUSION: The study findings underscore the inadequate disinfection of the inspiratory and expiratory branches, highlighting the importance of stringent cleaning and disinfection of high-touch surfaces.

General anesthesia versus conscious sedation in mechanical thrombectomy for patients with acute ischemic stroke: systematic review and meta-analysis / Anestesia geral versus sedação consciente na trombectomia mecânica para pacientes com AVC isquêmico agudo: revisão sistemática e metanálise

Abstract Background After recently published randomized clinical trials, the choice of the best anesthetic procedure for mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to large vessel occlusion (LVO) is not definite. Objective To compare the efficacy and safety of general anesthesia (GA) versus conscious sedation (CS) in patients with AIS who underwent MT, explicitly focusing on procedural and clinical outcomes and the incidence of adverse events. Methods PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials (RCTs) comparing GA versus CS in patients who underwent MT due to LVO-AIS. Odds ratios (ORs) were calculated for binary outcomes, with 95% confidence intervals (CIs). Random effects models were used for all outcomes. Heterogeneity was assessed with I2 statistics. Results Eight RCTs (1,300 patients) were included, of whom 650 (50%) underwent GA. Recanalization success was significantly higher in the GA group (OR 1.68; 95% CI 1.26-2.24; p < 0.04) than in CS. No significant difference between groups were found for good functional recovery (OR 1.13; IC 95% 0.76-1.67; p = 0.56), incidence of pneumonia (OR 1.23; IC 95% 0.56- 2,69; p = 0.61), three-month mortality (OR 0.99; IC 95% 0.73-1.34; p = 0.95), or cerebral hemorrhage (OR 0.97; IC 95% 0.68-1.38; p = 0.88). Conclusion Despite the increase in recanalization success rates in the GA group, GA and CS show similar rates of good functional recovery, three-month mortality, incidence of pneumonia, and cerebral hemorrhage in patients undergoing MT.

Resumo Antecedentes A trombectomia mecânica (TM) é o padrão de tratamento para pacientes com acidente vascular cerebral isquêmico agudo (AVCI) devido à oclusão de grandes vasos (OGV). No entanto, ainda não está claro qual é o procedimento anestésico mais benéfico para a TM. Objetivo Nosso objetivo foi comparar a eficácia e a segurança da anestesia geral (AG) versus sedação consciente (SC) em pacientes com AVCI submetidos à TM, focando especificamente nos resultados procedimentais e clínicos, bem como na incidência de eventos adversos. Métodos Foram realizadas buscas sistemáticas nas bases PubMed, Embase e Cochrane por ensaios clínicos randomizados (ECRs) comparando AG versus SC em pacientes submetidos à TM devido a AVCI por OGV. Razões de chances (ORs) foram calculadas para desfechos binários, com intervalos de confiança de 95% (ICs). Modelos de efeitos aleatórios foram usados para todos os resultados. A heterogeneidade foi avaliada com estatísticas I2. Resultados Oito ensaios clínicos randomizados (1.300 pacientes) foram incluídos, dos quais 650 (50%) foram submetidos à AG. O sucesso da recanalização foi significativamente maior no grupo AG (OR 1,68; IC 95% 1,26-2,24; p < 0,04) em comparação com SC. No entanto, não houve diferença significativa entre os grupos para recuperação funcional adequada (OR 1,13; IC 95% 0,76-1,67; p = 0,56), incidência de pneumonia (OR 1,23; IC 95% 0,56- 2,69; p = 0,61), mortalidade em três meses (OR 0,99; IC 95% 0,73- 1,34; p = 0,95) ou hemorragia cerebral (OR 0,97; IC 95% 0,68- 1,38; p = 0,88). Conclusão Apesar do aumento significativo nas taxas de sucesso de recanalização no grupo AG, AG e SC mostram taxas semelhantes de recuperação funcional, mortalidade, pneumonia e hemorragia em pacientes com AVCI submetidos à TM.

Post-operative nausea and vomiting prophylaxis: A meta-review on systematic reviews and meta-analyses

Introduction: Postoperative nausea and vomiting (PONV) are common complications in surgical patients undergoing general anesthesia, and multiple strategies have been suggested to prevent them. Objective: To describe the available evidence on the effectiveness of pharmacological and non-pharmacological strategies for preventing PONV in adults undergoing surgery under general anesthesia, as reported in previous meta-analyses and systematic reviews. Methodology: An overview of systematic reviews and meta-analyses was conducted. Searches were performed in PubMed, EBSCO, EMBASE, Cochrane Database, Science Direct, and Scopus, without restrictions as to gender, clinical condition, or date of publication, including articles in Spanish, French, and English only. Two reviewers independently and in duplicate did the screening, data extraction, quality evaluation, and risk of bias assessment according to AMSTAR-2. The PRISMA and PRIOR statements were followed for reporting. PROSPERO registration number CRD42021251999. Results: Out of 80 candidate articles, three were viable for meta-analysis. 1.5 mg to 18 mg doses of Dexamethasone showed a significant reduction in the risk of PONV, with a RR of 0.48 (95 % CI 0.41-0.57; p<0.001), I2=63 % (p=0.07), and a NNTc of 5 and 7. Other effective strategies included the use of acoustic stimulation/acupuncture/acupressure, 5HT3 antagonists, NK1 antagonists, gabapentinoids, haloperidol, droperidol, metoclopramide, midazolam, mirtazapine, among others. The risk of publication bias was low. Conclusion: Different strategies are effective for PONV prophylaxis in surgeries under general anesthesia. Dexamethasone shows the best available evidence at the moment. The documented methodological quality suggests the need for better studies to establish the effectiveness of the strategies.

Comparison of direct costs associated with the use of balanced general anesthesia and total intravenous anesthesia (TIVA) techniques / Comparación de los costos directos asociados al uso de técnicas de anestesia general balanceada y anestesia total intravenosa (TIVA)

Abstract Introduction: Healthcare costs are increasing against the backdrop of scarce resources. Surgical procedures are an important part of healthcare spending, and the cost of anesthetic techniques is relevant as part of the total cost of care and it is a potential target for expenditure optimization. Although important economic differences have been reported internationally for general anesthesia options, there are no publications in Colombia that compare current costs and allow for informed and financially responsible decision-making. Objective: To quantify and compare direct costs associated with the various general anesthesia options most frequently used at the present time. Methods: Cost minimization analysis based on a theoretical model of balanced general anesthesia using isoflurane, sevoflurane, desflurane in combination with remifentanil, and TIVA (propofol and remifentanil). Initial results were obtained using a deterministic simulation method and a sensitivity analysis was performed using a Monte Carlo simulation. Results: The average total cost per case for the different anesthetic techniques was COP 126381 for sevoflurane, COP 97706 for isoflurane, COP 288605 for desflurane and COP 222 960 for TIVA. Conclusions: Balanced general anesthesia with desflurane is the most costly alternative, 1.2 times more expensive than TIVA, and 2 and 3 times more costly than balanced anesthesia with sevoflurane and isoflurane, respectively. TIVA ranks second with a cost 1.8 times higher than balanced anesthesia with sevoflurane and 2.5 times higher than balanced anesthesia with isoflurane.

Resumen Introducción: Los costos de la atención en salud son crecientes y se enfrentan a un escenario de recursos escasos. La realización de procedimientos quirúrgicos hace parte importante de la atención y del gasto en salud, el costo de las técnicas anestésicas utilizadas es relevante en el costo total de la atención y es un objetivo potencial para la optimización del gasto. Aunque a escala internacional se han reportado diferencias económicas importantes entre las alternativas para anestesia general, en Colombia no se cuenta con publicaciones que comparen los costos actuales y permitan una toma de decisiones informada y responsable económicamente. Objetivo: Cuantificar y comparar los costos directos para Colombia de las diferentes alternativas para anestesia general usadas con más frecuencia en la actualidad. Métodos: Análisis de minimización de costos basado en un modelo teórico de anestesia general balanceada con isoflurano, sevoflurano, desflurano en combinación con remifentanilo y TIVA (propofol y remifentanilo). Se obtuvieron resultados iniciales utilizando una simulación con un método determinista y se realizó un análisis de sensibilidad con una simulación de Montecarlo. Resultados: El costo total promedio por caso para las diferentes técnicas anestésicas fue de COP 126.381 para sevoflurano, COP 97.706 para isoflurano, COP 288.605 para desflurano y COP 222.960 para TIVA. Conclusiones: La anestesia general balanceada con desflurano es la alternativa de mayor costo, es 1,2 veces más costosa que la TIVA, y 2 y 3 veces más que la balanceada con sevoflurano e isoflurano, respectivamente. La TIVA ocupa el segundo lugar con un costo 1,8 veces superior a la balanceada con sevoflurano y 2,5 veces a la balanceada con isoflurano.

Airway management in general anesthesia for endovascular treatment of cerebral arteriovenous malformation: a retrospective observational study.

BACKGROUND AND OBJECTIVE: This retrospective and observational study aimed to retrospectively evaluate the use of the endotracheal tube (ETT) and the Laryngeal Mask Airway (LMA) for the airway management with respect to airway safety, hemodynamic stability, adverse respiratory events, and recovery characteristics in patients who underwent endovascular treatment (EVT) for cerebrovascular arteriovenous malformation under general anesthesia between 2011 and 2018. METHODS: The study included data from the patient's electronic medical records and anesthesia files. The primary outcome measure was the incidence of hemodynamic disturbances and respiratory adverse events during airway management. The secondary outcome measure was the comparison of recovery characteristics. RESULTS: The airway was secured using ETT in 41 patients and LMA in 39 patients. Airway safety was established in all patients without a complication throughout the procedure. Mean arterial blood pressure and heart rate were increased to > 20% of baseline levels at intubation and extubation periods in more patients in the ETT group than the LMA group (27 vs. 3; p = 0.07, and 11 vs. 2; p = 0.021). Respiratory adverse events including straining and coughing were observed in ten patients in the ETT group but only in one patient in the LMA group (p = 0.013). Time to extubation, to neurological assessment, and to discharge from the angiography unit were similar (p > 0.05). CONCLUSION: It was concluded that LMA provided sufficient airway safety as with ETT and may be used as an alternative to ETT for EVTs under general anesthesia.

General anesthesia for old Werner syndrome patient: a case report.

Werner syndrome (WS) is a rare autosomal recessive, premature aging disorder whose clinical manifestations include short stature, bilateral cataracts, diabetes mellitus, hypertension, and atherosclerosis. WS first manifests during adolescence and patients usually die at 40-50 years of age. Only symptomatic treatment options available according to clinical manifestations. In anesthetic management, they need to be considered to elderly patients. Difficult intubation is expected and the patients are regarded as a high-risk group for anesthesia, owing to the concomitant cardiovascular and cerebrovascular disorders. The anesthetic management of WS requires a meticulous preoperative history taking, physical examination, and preparation for cardiovascular events.

The Effect of Hemodynamic Parameters on Cerebral Oxygenization During Carotid Endarterectomy.

OBJECTIVE/INTRODUCTION: Near-infrared spectroscopy (NIRS) is a non-invasive technique to detect cerebral ischemia by monitoring changes in regional cerebral oxygenation (rSO2) in the frontal lobes. However, there are no studies showing the changes in NIRS values in response to hemodynamic variations during stages of carotid endarterectomy (CEA) procedure and clinical implications of these changes. The aim of this study was to determine if hemodynamic changes affect NIRS values during carotid endarterectomy and if our results may help to provide strategies for hemodynamic management in these patients. METHODS: A total of 50 consecutive patients undergoing CEA were prospectively included in the study. NIRS was measured at first minute after clamping of carotid artery, and then systolic blood pressure was increased above 150 mmHg. NIRS values from both hemispheres were recorded simultaneously at certain time points and were analyzed to evaluate the changes at different stages of operation and to assess correlations with hemodynamic parameters. RESULTS: NIRS values on the right and left sides were correlated with systolic (right P<0.001, R2:0.24; left P=0.02, R2:0.10) diastolic (right P<0.001, R2:0.36; left P=0.001, R2:0.18) and mean (right P<0.001, R2:0.33; left P=0.003, R2:0.17) blood pressures when the patient was under general anaesthesia. NIRS values were significantly lower than pre-incision values just after clamping of carotid artery in both hemispheres (P=0.005 for the right and P<0.001 for the left side). CONCLUSION: NIRS values measured in our study show that there is a correlation between hemodynamic changes and cerebral oxygenation. This effect is especially pronounced while the patient is asleep and intubated, which implies the importance of close monitoring of patients with carotid disease during any surgery requiring general anaesthesia.

Comparación de máscaras laríngeas (I-gel Fastrach) para realización de intubación endotraqueal guiada con broncofibroscopio flexible / Comparison of I-gel Fastrach laryngeal masks in conducting flexible bronchofiberscope-guided

GOALS: Determine the success rate of guided intubation with a flexible bronchofibroscope (BFC) through supraglottic devices: I-gel or Fastrach, establish the degree of fibroscopic visualization and determine the insertion time of the laryngeal mask airway (LMA) and endotracheal intubation. METHODS: Experimental, prospective, comparative and randomized study of 60 ASA I-II-III patients, older than 18 years, undergoing elective surgeries that required general anesthesia and endotracheal intubation. After anesthetic induction, the assigned LMA was placed and intubation with BFC was performed through it. Both the success of laryngeal mask insertion and intubation were recorded, as well as the time (in seconds) equired for these procedures. The vision of the laryngeal structures was classified according to the Brimacombe Scale. RESULTS: The groups analyzed presented similar general characteristics. Insertion time of he LMA was significantly lower with I-gel than Fastrach (median 12 s vs 16 s. Respectively, p = 0.001). Also, in the intubation time BFC guided through the laryngeal mask, differences in favor of I-gel were found, with a median of 72 s. vs 89 s. (p = 0.001). Regarding the degree of glottic visualization with BFC, no statistically significant differences were found between both groups.CONCLUSIONS: Although both devices had the highest success rate (both in their placement and in intubation through them), with I-gel the intubation was performed quicker.

OBJETIVOS: Determinar la tasa de éxito de intubación guiada con broncofibroscopio flexible (BFC) a través de los dispositivos supraglóticos: I-gel o Fastrach, establecer el grado de visualización fibroscópica y determinar el tiempo de inserción de la máscara laríngea y de intubación endotraqueal. MATERIALES Y MÉTODOS: Estudio experimental, prospectivo, comparativo y aleatorizado de 60 pacientes ASA I- II ­III, mayores de 18 años, sometidos a cirugías electivas que requerían anestesia general e intubación endotraqueal. Luego de la inducción anestésica, se procedió a colocar la máscara laríngea asignada y se realizó la intubación con BFC a través de la misma. Tanto el éxito de inserción de máscara laríngea como de intubación fueron registrados, así como el tiempo (en segundos) requerido para dichos procedimientos. La visión de las estructuras laríngeas fue clasificada de acuerdo a Escala de Brimacombe. RESULTADOS: Los grupos analizados presentaron características generales similares. El tiempo de inserción de la ML fue significativamente menor con I-gel que con Fastrach (medianas: 12 s. vs 16 s. respectivamente, p = 0,001). También en el tiempo de intubación guiada con BFC a través de la máscara laríngea, se encontraron diferencias en favor de I-gel, con una mediana de 72 s. vs 89 s. (p = 0,001). Respecto al grado de visualización glótica con BFC, no se encontraron diferencias estadísticamente significativas entre ambos grupos. CONCLUSIONES: Aunque ambos dispositivos tuvieron la máxima tasa de éxito (tanto en su colocación como en la intubación a través de ellos), con I-gel se realizó la intubación de manera más rápida.

Flexible ureterorenoscopy and laser lithotripsy with regional anesthesia vs general anesthesia: A prospective randomized study

ABSTRACT Purpose To compare the effect of general anesthesia (GA) and regional anesthesia (RA) on f-URS outcomes and surgeon comfort. Material and Methods The study was conducted between June 2017 to January 2018 and data collection was applied in a prospective, randomized fashion. 120 patients participated in the study and were divided into RA group (n=56) and GA group (n=64). Demographic, operative and post-operative parameters of patients were analysed. The end point of this study was the effect of two anesthesia regimens on the comfort of the surgeon, and the comparability of feasibility and safety against perioperative complications. Results The study including 120 randomized patients, 14 patients were excluded from the study and completed with 106 patients (45 in RA group and 61 in GA group). No difference was detected between the two groups in terms of preoperative data. During the monitorization of operative vital signs, 3 patients in RA group experienced bradycardia, and this finding was significant when compared with GA group (p=0.041). Additionally, 2 patients in RA group experienced mucosal tears and 1 patient experienced hemorrhage during the operation, but no complications were observed in the GA group (p=0.041). Postoperative surgeon comfort evaluation revealed statistically significant results in favor of GA group (p=0.001). Conclusions Both GA and RA are equally effective and safe anesthesia methods for f-URS procedures. However, RA group showed significantly increased likelihood of bradycardia and mucosal injury during surgery, and significantly decreased surgeon comfort during surgery.

(1.96) Margen de error (e): 5% Probabilidad de ocurrencia del evento (p): 15% Probabilidad de no ocurrencia del evento (q): 85%. Resultados: 220 casos ingresados al estudio. El índice de complicaciones laríngeas es 5.9% , frecuentemente la tos y secreción sanguinolenta, asociándose factores como mascara clásica, edad (2-5 años), tiempo mayor de 60 minutos, mayor número de intentos, ASA> I, estado nutricional sobrepeso, e insertar en formación. Conclusión: La máscara laríngea es validada como dispositivo en anestesia pediátrica por aprendizaje rápido, baja tasa de fracaso, menores complicaciones y utilidad en vías aéreas difíciles, Es insuficiente la evidencia para respaldar el uso de un determinado dispositivo por encima de otro

Introduction: The laryngeal mask is the equipment with the aim of increasing quality, safety, care, however, despite having universal use and high efficacy for ventilation, it is not without complications. The objective of this research was to identify the frequency of complications with the use of a laryngeal mask in the Vicente Corral Moscoso and José Carrasco public hospitals in the city of Cuenca. Methods: It is an observational, descriptive, prospective study in 220 pediatric patients, ASA I, II and III who underwent elective and emergent surgeries under general anesthesia in a time interval of 30 to 240 minutes, of all surgical medical specialties of the year 2018, the different types of mask were used. The sample was obtained by applying the formula for unknown population (n = (Z2 x p x q) / e2), confidence level (Z): 95%. (1.96) Margin of error (e): 5% Probability of occurrence of the event (p): 15% Probability of non-occurrence of the event (q): 85%. Results: 220 cases entered the study. The rate of laryngeal complications is 5.9%, frequently cough and bloody discharge, associating factors such as classic mask, age (2-5 years), time greater than 60 minutes, greater number of attempts, ASA> I, nutritional status, overweight, and insert in formation. Conclusion: The laryngeal mask is validated as a device in pediatric anesthesia due to rapid learning, low failure rate, fewer complications and usefulness in difficult airways. The evidence is insufficient to support the use of a certain device over another.

The effect of prophylactic rewarming on postoperative nausea and vomiting among patients undergoing laparoscopic hysterectomy: a prospective randomized clinical study

ABSTRACT BACKGROUND: Postoperative nausea and vomiting (PONV) is a common complication from general anesthesia that impacts on postoperative recovery. OBJECTIVE: To evaluate prophylactic rewarming following general anesthesia, so as to decrease the incidence of PONV among patients undergoing laparoscopic hysterectomy. DESIGN AND SETTING: Prospective randomized clinical study at a hospital in China. METHODS: Sixty-two patients were randomly assigned into two groups. The forced air warming (FAW) group received pre-warmed Ringer's solution with FAW until the end of surgery. The control group received Ringer's solution without FAW. The pre-warmed Ringer's solution was stored in a cabinet set at 40 °C. The FAW tube was placed beside the patient's shoulder with a temperature of 43 °C. RESULTS: Sixty patients completed the study. The FAW group showed significant differences versus the controls regarding temperature. At 6, 24 and 48 hours postoperatively, the incidences of PONV were 53.3%, 6.7% and 3.3% in the FAW group versus 63.3%, 30% and 3.3% in the controls. VAS scores were significantly lower in the FAW group than in the controls at 24 hours (P= 0.035). Forty-item questionnaire total scores in the FAW group were significantly higher than in the controls. The physical independence and pain scores at 24 hours and emotional support and pain scores at 48 hours in the FAW group were higher than in the controls (P < 0.05). There was no difference in hemodynamics or demographics between the two groups (P > 0.05). CONCLUSIONS: Prophylactic rewarming relieved PONV and improved the quality of postoperative recovery.

Ventajas de la anestesia intravenosa libre de opioides en cirugía ambulatoria oncológica de mama / Advantages of opioid-free intravenous anesthesia over anesthesia in ambulatory breast cancer surgery

RESUMEN Introducción: la anestesia general libre de opioides surge ante la necesidad de evasión del uso de opioides en el transoperatorio y sus efectos indeseados en el posoperatorio. Objetivo: evaluar el comportamiento hemodinámico y la recuperación anestésica en pacientes intervenidas mediante cirugía ambulatoria por cáncer de mama, en las cuales se administró anestesia general total intravenosa libre de opioides o general balanceada. Métodos: se realizó un estudio cuasiexperimental, prospectivo en pacientes a las que se aplicó anestesia general balanceada (n=34) y total intravenosa libre de opioides (n=34) intervenidas quirúrgicamente por cáncer de mama, en el Hospital General Docente "Abel Santamaría Cuadrado", durante el 2018. Resultados: el grupo de anestesia general balanceada mostró mayor variación intraoperatoria de los parámetros evaluados, con diferencias significativas (p=0,019). El tiempo medio de despertar fue menor en el grupo de anestesia total intravenosa (2,10 ± 0,907 min vs 5,35 ± 1,250 min; p<0,01), al igual que el dolor, con diferencia significativa (p<0,05) y el tiempo de recuperación, donde una hora después de la intervención, el 85 % cumplía los criterios de alta anestésica. El retraso en el alta de la unidad de recuperación ocurrió principalmente por el bajo nivel de actividad motora, con mayor incidencia en el grupo de anestesia general balanceada (71 % vs 26 %; p=0,00). Conclusiones: la anestesia total intravenosa libre de opioides fue superior al método general balanceado, pues mostró mayor estabilidad hemodinámica y analgesia, menor incidencia de complicaciones posoperatorias y menor tiempo de estancia en sala de recuperación posanestésica.

ABSTRACT Introduction: opioid-free general anesthesia arises from the need to avoid the use of opioids in the transoperative period and the undesirable effects in the postoperative period. Objective: to assess the hemodynamic behavior and anesthetic recovery in patients who underwent ambulatory surgery for breast cancer and those who were given either opioid-free intravenous general or balanced general anesthesia. Methods: a quasi-experimental, prospective study was carried out on patients who received balanced general anesthesia (n=34) and total opioid-free intravenous anesthesia (n=34), who underwent breast cancer surgery at Abel Santamaria Cuadrado General Teaching Hospital during 2018. Results: the group of balanced general anesthesia showed greater intraoperative variation of the parameters assessed, with significant differences (p=0.019). The mean time of awakening was lower in the intravenous total anesthesia group (2.10 ± 0,907 min vs. 5,35 ± 1,250 min; p<0.01), as was pain, with significant difference (p<0.05) and the recovery time, where one hour after the surgery, 85 % met the criteria for anesthesia discharge. The delay in discharge from the recovery unit occurred mainly because of the low level of motor activity, with a higher incidence in the group of balanced general anesthesia (71% vs. 26 %; p=0.00). Conclusions: intravenous opioid-free total anesthesia was higher to the balanced general approach because it showed greater hemodynamic and analgesic stability, lower incidence of postoperative complications, and shorter time spent in the post-anesthesia recovery room.

Primary Tooth Extraction Pattern Among Turkish Children with Severe Early Childhood Caries Treated Under General Anesthesia

Abstract Objective: To determine the frequency and distribution of extracted primary teeth due to severe Early Childhood Caries (ECC) in young pediatric patients treated under general anesthesia. Material and Methods: This study employed a retrospective design and consisted of a total of 1644 children (1011 boys, 633 girls) children aged 3 to 5 who had been diagnosed with several ECC and treated under general anesthesia in a dental faculty between 2013-2019. The data was obtained from the medical and dental forms obtained from the faculty database. The patients were divided according to age groups and sex. A total of 2605 teeth were classified according to the sex, tooth number, and age groups. Results: Of the subjects, 14% (n = 245) were 3 years old, 31% (n = 505) were 4 years old, 55% (n = 894) were 5 years old. The mean ± SD age of subjects was 4.2 ± 0.8 yr. While the most extracted teeth were found to be maxillary primary central incisors and molar teeth, the less were found to be mandibular primary canines. While there was a statistically significant difference between canines and incisors with molars (p<0.05), no difference existed between incisors and molars. There was a statistically significance difference among all age groups (p<0.05). While 3 years old group had the less number of extracted teeth, 5 years old group had the most number of extracted teeth. Conclusion: Severe ECC causes higher tooth extraction in patients treated under general anesthesia. Effective personal and community programs should be initiated to prevent ECC and mitigate its potential disruptive impacts in children's oral health.
