Retrospective Analysis of the Clinical Efficacy of Early Goal-Directed Therapy Combined with Meticulous Nursing Intervention in Patients with Posttraumatic Sepsis

Objective. To explore the intervention effect of early goal-directed therapy (EGDT) combined with meticulous nursing on patients with posttraumatic sepsis. Methods. The data of 50 patients with posttraumatic sepsis undergoing EGDT in the emergency department of our hospital from January 2020 to December 2020 were retrospectively analyzed. According to different nursing methods, they were divided into control group (n = 25) with routine nursing measures and observation group (n = 25) with meticulous nursing measures. The application effect of the two nursing modes was scientifically evaluated. Results. No statistical differences in general data were found between the two groups ( P > 0.05 ). After 6 h of intervention, the circulatory function, oxygenation function, and renal function of both groups were better than those before intervention, and central venous pressure (CVP), mean arterial pressure (MAP), blood oxygen (PaO2), oxygenation index (PaO2/FiO2), central venous oxygen saturation (ScvO2), and urine volume in the observation group were notably higher than those in the control group ( P < 0.05 ). The heart rate (HR), serum creatinine (SCr), and blood lactic acid in the observation group were notably lower than those in the control group ( P < 0.05 ). The 28-day survival rate and quality of life after intervention in the observation group were notably higher than those in the control group, with obvious differences between the two groups ( P < 0.05 ). Conclusion. Meticulous nursing intervention for patients with posttraumatic sepsis undergoing EGDT can effectively improve the body’s functional indexes, which is superior to the routine nursing in controlling the patients’ condition, improving the survival rate and quality of life after intervention, and ensuring the clinical treatment effect. Therefore, it is worthy of promotion.

Comparison of Intermittent versus Continuous Superior Venal Caval Oxygen Saturation Monitoring in Early Goal Directed Therapy in Septic Shock: A Systematic Review

Early goal directed therapy (EGDT) is a bundle of care (monitoring ScvO2 and lactate along with clinical parameters and instituting therapy) that has shown to improve outcomes in patients with septic shock. We conducted a systematic review of clinical trials and observational studies to compare intermittent versus continuous monitoring of ScvO2. We did major database searches till August 2020. Hospitalized children (>2 months age) and adults with septic shock were included. The intervention was “intermittent ScvO2 monitoring,” and the comparator was “continuous ScvO2 monitoring.” The primary outcome is “all-cause mortality.” Of 564 citations, 3 studies (n = 541) including both children and adults were included in the analysis. There was no significant difference in the “overall/all-cause mortality” (two randomized controlled trials; 258 participants) between the “intermittent” and “continuous” ScvO2 monitoring groups (relative risk [RR]: 1.00; 95% confidence interval [CI]: 0.8–1.24). However, a single observational study (283 participants) showed a significant increase in mortality in the intermittent group (RR: 1.46; 95% CI: 1.03–2.05). The GRADE evidence generated for “overall/all-cause mortality” was of “moderate certainty.” To conclude, the present meta-analysis did not find any significant difference between “intermittent” and “continuous” ScvO2 monitoring in patients with septic shock.

Efficacy of Intraoperative Hemodynamic Optimization Using FloTrac/EV1000 Platform for Early Goal-directed Therapy to Improve Postoperative Outcomes in Patients Undergoing Coronary Artery Bypass Graft with Cardiopulmonary Bypass: A Randomized Controlled Trial

Background: Early goal-directed therapy (EGDT) using the FloTrac system reportedly decreased mortality, morbidity, and length of stay (LOS) in intensive care unit (ICU) and hospital among high-risk patients undergoing non-cardiac surgery. The objective of this study was to evaluate the efficacy of the FloTrac/EV1000 platform for improving postoperative outcomes in cardiac surgery. Methods: Eighty-six adults undergoing coronary artery bypass graft (CABG) with cardiopulmonary bypass (CPB) were randomized to the EV1000 or Control group. The Control group was managed with standard care to achieve the following goals: mean arterial pressure 65-90 mmHg; central venous pressure 8-12 mmHg; urine output ≥ 0.5 mL/kg/h; oxygen saturation > 95%; and hematocrit 26-30%. The EV1000 group was managed to reach similar goals using information from the FloTrac/EV1000 monitor. The targets were: stroke volume variation (SVV) < 13%; cardiac index (CI) 2.2-4.0 L/min/m2; stroke volume index (SVI) 33‑65 mL/beat/m2; and systemic vascular resistance index (SVRI) 1600‑2500 dynes/s/cm5/m2. Results: The LOS in ICU of the EV1000 group was significantly shorter (mean difference -29.5 h; 95%CI -17.2 to -41.8, p < 0.001). The mechanical ventilation time was also shorter in the EV1000 group (mean difference -11.3 h; 95%CI -2.7 to -19.9, p = 0.011). The hospital LOS was shorter in the EV1000 group (mean difference -1.1 d; 95%CI -0.1 to -2.1, p =0.038). The EV1000 group received a higher number of inotropic or vasoactive drugs than the Control group in pre-bypass period, but less in post-bypass, postoperative period before transfer to the ICU, and in the ICU. The EV1000 group had less atrial fibrillation with rapid ventricular response, acute respiratory distress syndrome, and acute renal injury.Conclusions: Compared with standard care, intraoperative hemodynamic optimization using the FloTrac/EV1000 platform for the EGDT protocol in patients undergoing CABG with CPB resulted in shorter ventilator time, shorter ICU and hospital LOS, and fewer postoperative complications. The EV1000 group required more fluid and inotropic or vasoactive drugs in the pre-bypass period to optimize SVV, CI, and SVRI and to maintain the target MAP resulting in better myocardium oxygen supply reflected in fewer drugs required during post-bypass, before transfer to, and in, the ICU.Trial registrationThe study was registered with ClinicalTrials.gov (NCT04292951) on 03/03/2020.

Feasibility and beneficial effects of an early goal directed therapy after cardiac arrest: evaluation by conductance method

Although beneficial effects of an early goal directed therapy (EGDT) after cardiac arrest and successful return of spontaneous circulation (ROSC) have been described, clinical implementation in this period seems rather difficult. The aim of the present study was to investigate the feasibility and the impact of EGDT on myocardial damage and function after cardiac resuscitation. A translational pig model which has been carefully adapted to the clinical setting was employed. After 8 min of cardiac arrest and successful ROSC, pigs were randomized to receive either EGDT (EGDT group) or therapy by random computer-controlled hemodynamic thresholds (noEGDT group). Therapeutic algorithms included blood gas analysis, conductance catheter method, thermodilution cardiac output and transesophageal echocardiography. Twenty-one animals achieved successful ROSC of which 13 pigs survived the whole experimental period and could be included into final analysis. cTnT and LDH concentrations were lower in the EGDT group without reaching statistical significance. Comparison of lactate concentrations between 1 and 8 h after ROSC exhibited a decrease to nearly baseline levels within the EGDT group (1 h vs 8 h: 7.9 vs. 1.7 mmol/l, P < 0.01), while in the noEGDT group lactate concentrations did not significantly decrease. The EGDT group revealed a higher initial need for fluids (P < 0.05) and less epinephrine administration (P < 0.05) post ROSC. Conductance method determined significant higher values for preload recruitable stroke work, ejection fraction and maximum rate of pressure change in the ventricle for the EGDT group. EGDT after cardiac arrest is associated with a significant decrease of lactate levels to nearly baseline and is able to improve systolic myocardial function. Although the results of our study suggest that implementation of an EGDT algorithm for post cardiac arrest care seems feasible, the impact and implementation of EGDT algorithms after cardiac arrest need to be further investigated.

Echocardiography-Guided Hemodynamic Management of Severe Sepsis and Septic Shock in Adults: A Randomized Controlled Trial

Background: Echocardiography (ECHO) is used to guide septic shock resuscitation, but without evidence for efficacy. Therefore, we compared the outcome of early goal-directed therapy (EGDT) and ECHO-guided management of hemodynamics in severe sepsis and septic shock. Materials and Methods: This is a single center, randomized controlled trial conducted on 100 adult patients with severe sepsis or septic shock. Patients were assessed and treated with either EGDT protocol (EGDT group) or ECHO-guided resuscitation protocol (ECHO group). Results: Only 87 patients (45 in group I and 42 in group II) were analyzed. There was a significant increase of mean norepinephrine and dobutamine doses and a significant decrease in total fluids in the first 24 hours, time to normalization, time to weaning of vasopressors, total MV days, MV free days and ICU and hospital stays in ECHO group. At 30 days, the mortality rate in EGDT group was 35.6% which was significantly higher compared to 14.3% in ECHO group. At 90 days, the overall mortality was significantly higher in EGDT group compared to Echo group (40.0% vs 16.7% respectively). Hazardous ratio of mortality was 1.630 (95% confidence interval (CI): 1.123 - 2.366) and 1.653 (95% CI: 1.137 - 2.404) at 30 and 90 days respectively in EGDT group compared to ECHO group. Conclusions: In severe sepsis and septic shock, ECHO-guided management of hemodynamics resulted in a decrease in mortality, lower total fluid intake, higher vasopressor and inotrope support, earlier weaning of vasopressors and less MV days, ICU and hospital stay.

Septic shock in children

Chapter 1 begins by examining the definitions of sepsis and septic shock as subsets of the systemic inflammatory response syndrome, discusses the epidemiology of paediatric sepsis, and provides a structured approach to the assessment of a child with suspected sepsis. The evidence for and limitation of investigations, such as lactate measurement and attempted quantification of cardiac function in paediatric sepsis, is examined. Optimal management strategies for paediatric sepsis remain much studied and debated. This chapter addresses the use of inotropes—both early inotropes and choice of inotropes, intravenous fluids, including the current evidence base for choice of fluids, and the increasingly studied areas of fluid overload and fluid removal (de-resuscitation) following the initial phases of resuscitation. The evidence base for use and timing of antibiotics and steroids is discussed, along with the roles of the supportive therapies renal replacement therapy and extracorporeal membrane oxygenation. Finally, the chapter examines some of the key aspects of the care of patients with sepsis of relevance to intensivists: early goal-directed therapy; sepsis bundles; and the Surviving Sepsis Campaign.
