Subjects: CESAREAN section, HYPOTENSION, SPINAL anesthesia, BODY mass index, NEWBORN infants
Abstract (English): Introduction: Because of its incidence, hypotension under spinal anesthesia has been the subject of study and debate. Studies have been aimed at defining risk factors, clarifying pathophysiology, and creating prophylaxis and management protocols. There are no studies of anthropometric measurements, such as waist-tohip ratio (WHR) and body mass index (BMI), associated with maternal hypotension. The higher the content of the abdominal cavity, the greater the likelihood of aorto-caval compression syndrome and the higher the risk of hypotension. Objective: To determine if the WHR and the BMI correlate with the probability of developing hypotension in pregnant women undergoing cesarean section under subarachnoid anesthetic block. Materials and methods: A prospective cohort study of 231 women undergoing cesarean section under regional anesthesia. Anthropometric measurements were made before anesthesia, and vital signs were recorded during the procedure at predetermined time points to analyze the hemodynamic status. Hypotension was defined as a systolic blood pressure below 90 mm Hg. Results: The incidence of hypotension was 38%; 45.8% of the women had a WHR >0.99, with an incidence of 21.7% versus 15.2%, and a nonsignificant risk ratio of 2.12 (95% confidence interval [CI] 1.52-3.54, P=0.021). Women with a BMI >29 had an incidence of 42.8% versus 57.14%, without a significant difference (P=0.576). There was a significant association between the weight of the newborn >3900g and the risk of hypotension (relative risk 2.12, 95% CI 1.52-3.54, P=0.021). Conclusion: There was no positive correlation between WHR and BMI, and the risk of developing hypotension. The weight of the newborn must be further analyzed in future studies. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Introducción: La hipotensión bajo anestesia regional subaracnoidea ha sido tema de estudio y debate, dada su alta incidencia. Los estudios se han encaminado a encontrar factores de riesgo, estudiar fisiopatología, crear protocolos demanejo y profilaxis. No hay estudios de medidas antropométricas, como el índice de relación cintura-cadera (IRCC) e Índice de masa corporal (IMC) asociados a hipotensión en maternas. A mayor contenido en cavidad abdominal, mayor probabilidad de síndrome de compression aorto-cava y mayor riesgo de hipotensión. Objetivo: Determinar si el Índice de Relación Cintura Cadera y el Índice de masa Corporal se correlacionan con la probabilidad de desarrollar hipotensión en gestantes sometidas a Cesárea bajo anestesia subaracnoidea. Materiales y métodos: Estudio analítico de cohorte prospectivo. 231 maternas sometidas a cesárea bajo anestesia regional; se tomaron medidas antropométricas antes de anestesia, se registraron signos vitales durante el procedimiento en momentos preestablecidos para analizar el comportamiento hemodinámico. Se definió hipotensión como tensión arterial sistólica< 90mmHg. Resultados: La incidencia de hipotensión fue 38%. El 45,8% tuvieron IRCC >0,99 con incidencia de hipotensión de 21,7% vs 15.2% y RR no significativo de 2.12 (IC95% 1.52-3.54 p=0.021). Pacientes con IMC>29 la incidencia de hipotensión fue 42,8% versus 57.14%, sin diferencias significativas. (p=0,576). El peso del recién nacido >3.900 gramos se asoció significativamente con riesgo de hipotensión; RR:2.12 (IC95% 1.52-3.54 p=0.021). Conclusiones: EL Índice Cintura Cadera y el Índice de Masa Corporal no presentaron correlación positiva con el riesgo de presentar hipotensión. El peso del recién nacido debe documentarse en futuros estudios. [ABSTRACT FROM AUTHOR]
