UTILIDAD CLÍNICA DE DOS DISPOSITIVOS DE ACCESO VASCULAR PARA INFUSIONES INTRAVENOSAS DURANTE LA HEMORRAGIA POSPARTO

Resumen

OBJECTIVE. This study examined the clinical utility of using two vascular access devices for intravenous infusions in women who experienced postpartum hemorrhage during cesarean section. METHODS. A case-control study was designed to evaluate the characteristics of the vascular access device used for intravenous infusions in 186 women selected by simple random sampling and assigned to two groups: the group that experienced hemorrhage (n=31) and the control or non-hemorrhage group (n=155). Linear regression assessed the relationship between hemorrhage and the predictors of intravascular therapy. RESULTS. During cesarean section, 31 women had hemorrhage, bleeding on average 1,129 ml with a dispersion of 560 ml, with a statistical difference of means between both groups in the t test of -14.74, and a p value of 0.001. The most commonly used vascular device was the 18-gauge peripheral catheter with 60%, and the 14-gauge was the least commonly used with 2.7%. In the group with hemorrhage, 83.9% used a peripheral catheter, 35.5% had two catheters, and 48.4% had the appropriate catheter (14 or 16 gauge). Linear regression with R 0.801 and ANOVA p 0.001, identifying a statistical relationship between the vascular device and hemorrhage. CONCLUSIONS. In evaluating the clinical utility of two vascular devices during postpartum hemorrhage, it was found that both groups mainly used the 18-gauge peripheral catheter and in cases of hemorrhage, only a third of the women had a double device and half had an appropriate large-caliber catheter for intravenous infusion.
