Overview
Brief Summary
This clinical study aims to compare the recent septic shock management protocol from American College of Critical Care Medicine (ACCM) to Ultrasound-guided Septic Shock Management (USSM) protocol. USSM protocol laid on Doppler ultrasonography to evaluate stroke volume, cardiac index, and systemic vascular resistance in each step of management to decide the proper fluid resuscitation and vasoactive therapy; differs from ACCM protocol which use clinical finding in its early step. ACCM protocol application elicits risk of improper therapy since clinical sign per se often could not describe the certain cardiac output. This can be prevented earlier by USSM protocol. The outcome compared of the two protocols is: mortality rate, clinical parameter, macrocirculation hemodynamic parameter, laboratory microcirculation parameter, and signs of fluid overload. The investigators hypothesized if the USSM protocol had a better outcome and less fluid overload complication.
Detailed Description
This study is a randomized controlled trial to compare the usage of ACCM protocol and USSM protocol in fluid resuscitation for septic shock pediatric patients. The USSM protocol is the intervention, and the ACCM protocol is the control. This study implemented in septic shock pediatric patients treated in the intensive care unit. Each patient will be randomized into 2 groups, the USSM group or the ACCM group. In the initial step, all patient in each group will receive early acute/emergency therapy: oxygen support, vascular access, and fluid resuscitation. The monitoring of the patient including clinical parameters and laboratory examination for both groups, except Doppler ultrasonography that performed in each step of management of the intervention group. The monitoring is performed every 15 minutes in the first hour of resuscitation. If the patient show good response (fluid responsive shock), the monitoring stops in 1 hour. In contrast, if the patient reveal fluid refractory shock, the vasoactive agent will be administered and monitoring continues until 6 hours. All outcome parameters, except mortality rate, will be recorded at 6 hours. The mortality rates will be recorded at 72 hours and time of intensive care discharge. Sample size in this study was calculated by clinical trial formula for mortality rate with a significance level of 0.05 and study power of 0.2. From the calculation, the subject needed is 170 patients for each group (total 340 subjects). The basic characteristics of the patient will be analyzed descriptively. All parameter data will be analyzed statistically by Statistical Product and Service Solution (SPSS) 20, preceded by normality test and homogeneity test. The study analysis will be intention-to-treat. The mortality rate was analyzed by Kaplan-Meier survival analysis. Data transformation will be performed if needed in case of outlier data or out-of-range results.
