¿Podría ser útil la puntuación Apgar quirúrgica para predecir las complicaciones postoperatorias tras la cirugía de fractura femoral proximal? Un estudio retrospectivo de cohorte / Would surgical Apgar score be useful to predict postoperative complications after proximal femoral fracture surgery? A retrospective cohort study

Antecedentes: El Apgar quirúrgico (AQ) es una puntuación evaluadora del riesgo perioperatorio, que evalúa intraoperatoriamente la frecuencia cardiaca mínima, la presión arterial media mínima y la pérdida de sangre estimada. Aunque ha sido validado en múltiples campos quirúrgicos, el AQ sigue siendo controvertido en el campo traumatológico. El objetivo principal de este estudio fue investigar si AQ guarda relación con la incidencia de complicaciones durante los primeros 30 días tras la cirugía de fractura femoral proximal. Métodos: Estudio retrospectivo que incluyó todos los pacientes consecutivos sometidos a cirugía de fractura femoral proximal entre enero y julio de 2019. Se excluyó a los pacientes que carecieran de información sobre el AQ. Se dividió a los pacientes en dos grupos, sobre la base de la incidencia de complicaciones durante los primeros 30 días postoperatorios y el cálculo de su AQ. Se utilizaron curvas ROC (característica operativa del receptor) para evaluar el modelo predictivo de complicaciones. Resultados: El 44% (n = 76) de los 181 pacientes incluidos en el estudio desarrollaron complicaciones durante los primeros 30 días postoperatorios. Ocho pacientes (4,4%) fallecieron durante dicho periodo. La edad media de los pacientes fue de 79 años, y el 30,9% (n = 56) fueron varones. La insuficiencia cardiaca (IC), el uso de marcapasos, la enfermedad renal crónica, la enfermedad pulmonar obstructiva crónica y la demencia estuvieron significativamente asociadas a la morbilidad postoperatoria. No existió correlación significativa entre AQ y la incidencia de complicaciones durante los primeros 30 días postoperatorios. El ABC de AQ como modelo predictivo de complicaciones postoperatorias tras la cirugía de fractura femoral proximal fue de 0,522, lo cual es insuficiente para poder considerarse un modelo predictivo aceptado. Conclusión: Sobre la base de este estudio, concluimos que AQ no es predictivo del desarrollo de complicaciones en los primeros...(AU)

Background: The surgical Apgar score (SAS) is a perioperative risk evaluation score, which considers intraoperative minimum heart rate, minimum mean arterial pressure and estimated blood loss. Although validated in multiple surgical fields, SAS remains quite controversial in the orthopedic one. The main purpose of this study was to investigate if SAS relates with the occurrence of complications during the first 30-days after proximal femoral fracture surgery. Methods: Retrospective study including all consecutive patients submitted to proximal femoral fracture surgery between January and July 2019. Patients with no information about SAS were excluded. Patients were divided in two groups, based on the occurrence of complications during the first 30 post-operative days and their SAS calculated. Receiver operating characteristic (ROC) curves were used to assess SAS power as a predictive model of complications. Results: Forty-two percent (n = 76) of the 181 patients included in the study developed complications during the first 30 postoperative days. Eight patients (4,4%) died during that period. The patient's mean age was 79 years and 30,9% (n = 56) were men. Heart failure, pacemaker use, chronic kidney disease, chronic obstructive pulmonary disease and dementia were significantly associated with post-operative morbidity. There was no significant correlation between SAS and the occurrence of complications during the first 30 postoperative days. The AUC of SAS as a predictive model for postoperative complications after proximal femoral fracture surgery was 0,522, being insufficient to be considered an accepted model of prediction. Conclusion: Based on this study, we conclude that SAS is not predictive of the development of complications in the first 30 post-operative days in patients submitted to proximal femoral fracture surgery. However, other clinical factors have been identified as associated with postoperative morbidity...(AU)

Apgar quirúrgico como criterio de activación de código 77 en el Hospital Ángeles Pedregal / Surgical Apgar score as a criteria for activation of code 77 at Angeles Pedregal Hospital

Resumen: Introducción: El Apgar quirúrgico (AQ) es un sistema de 10 puntos que valora tres variables intraoperatorias: frecuencia cardíaca más baja, presión arterial media más baja y sangrado. El AQ es un indicador de la mortalidad y morbilidad en el postoperatorio inmediato. Objetivo: Describir la incidencia del puntaje AQ en pacientes postoperados y con activación del código 77 en el Hospital Ángeles Pedregal. Material y métodos: Estudio observacional, descriptivo, retrospectivo, de corte transversal que incluyó pacientes con indicación de activación del código 77 en su postoperatorio inmediato y traslado a Unidad de Cuidados Intensivos, durante el período de enero a diciembre de 2015 en el Hospital Ángeles Pedregal. Resultados: Se contó con 58 pacientes de los cuales 68% obtuvieron un Apgar quirúrgico ≥ 7 puntos (estables) y 32% un Apgar quirúrgico 6 (inestables). La incidencia del Apgar quirúrgico 6 para el período de estudio fue de 12 casos por cada 100 personas intervenidas con una sensibilidad del 68%. Conclusiones: El AQ puede considerarse un criterio confiable para la activación del código 77 en aquellos pacientes con puntaje AQ ≤ 6 durante el postoperatorio inmediato, permitiendo un manejo oportuno de las complicaciones postquirúrgicas y la disminución de riesgo de morbimortalidad.

Abstract: Introduction: The surgical Apgar score (SAS) is a 10-point system that assesses three intraoperative variables: lower heart rate, lower mean arterial pressure, and bleeding. SAS is an indicator of mortality and morbidity in the immediate postoperative period. Objective: To describe the incidence of the SAS in postoperative patients with activation of code 77. Material and methods: Observational, transversal, retrospective and descriptive study, included patients with indication of activation of code 77 during their immediate postoperative time, and transferred to the Intensive Care Unit, during the period from January to December 2015. Results: 68% of the sample obtained a SAS greater than or equal to 7 points (stable patient), and 32% a SAS less than or equal to 6 (unstable). The incidence of SAS less than or equal to 6 points for the period of the study was about 12 cases per 100 persons intervened with a sensibility of 68%. Conclusions: SAS should be taken as another criteria for the activation of code 77 in those patients with a result lower than 6 points; during the immediate postoperative period, allowing a timely management of postoperative complications and a reduction on the risk of morbidity and mortality.

Surgical Apgar score as a complication predictor in gastrointestinal oncologic surgery.

INTRODUCTION AND AIMS: Surgical resection of gastrointestinal (GI) cancer is the cornerstone of curative treatment but entails considerable morbidity. The surgical Apgar score (SAS) is a practical and objective instrument that provides immediate feedback. The aim of the present study was to evaluate the performance of the SAS for predicting complications at 30 days in patients with primary GI cancer that underwent curative surgery. MATERIALS AND METHODS: A prospective observational study was conducted that included 50 patients classified into a low SAS (≤ 4) group or a high SAS (≥ 5) group. Complications were defined as any event classified as a Clavien-Dindo grade II to V event. Bivariate and multivariate analyses were performed through the Cox regression and a p<0.05 was considered significant. RESULTS: Overall postoperative morbidity was 50.0%, with no mortality. Eighty-six percent of cases were catalogued as having an ASA≥3. Eighty-eight percent had a high SAS, of whom 45.5% presented with a complication, whereas 12.0% had a low SAS and a complication rate of 83.3%. In the multivariate analysis, the BMI (OR: 3.351, 95% CI: 1.218-9.217, P=.019), SAS (OR: 0.266, 95% CI: 0.077-0.922, P=.037), surgery duration (OR: 3.170, 95% CI: 1.092-9.198, P=.034), and ephedrine use (OR: 0.356, 95% CI: 0.144-0.880, P=.025) were significantly associated with the development of adverse outcomes. CONCLUSIONS: SAS was shown to be an independent predictive factor of postoperative morbidity at 30 days in the surgical management of GI cancer and appears to offer a reliable sub-stratification in a high-risk population with an ASA≥3.
