Refractory septic shock (Part 1)

Refractory septic shock develops in 6–7% of sepsis patients with short-term lethality rate of more than 50%. It is necessary to assess the effectiveness of intensive therapy methods used in this case.The objective of the review: to analyze publications on the intensive care of refractory septic shock.Results. 56 studies published in the period from January 1, 1990 to September 1, 2020 were analysed, they reflect the effectiveness of some methods used for management of refractory septic shock (treatment of the underlying disease, liquid bolus, the use of norepinephrine, adjuvant therapy, management of metabolic acidosis). The second part of this article will reflect the evaluation of the effectiveness of other approaches to the treatment of this complication.

Refractory Septic Shock

Refractory shock is the shock that does not respond to vasopressor therapy. Refractory shock with a short-term mortality rate of more than 50% is diagnosed in 6-7% of critically ill patients. There is an objective need to Investigate methods of intensive therapy for refractory septic shock.The objective of the study: to analyze literature data on the intensive care of refractory septic shock.Results. The second part of the article analyzes 37 studies, both Russian and foreign ones devoted to the intensive care of refractory shock. At present, based on the analysis of the publication, it is impossible to draw reasonable conclusions about the advantage of one or another method of intensive therapy for refractory shock (veno-venous hemofiltration, the use of angiotensin II and vasopressin, as well as methylene blue, vitamin B12, ECMO) over basic therapy.

Abstract Background The European Society of Pediatric and Neonatal Intensive Care (ESPNIC) developed and validated a definition of pediatric refractory septic shock (RSS), based on two septic shock scores (SSS). Both bedside SSS (bSSS) and computed SSS (cSSS) were found to be strongly associated with mortality. We aimed at assessing the accuracy of the RSS definition on a prospective cohort from India. Methods Post hoc analysis of a cohort issued from a double-blind randomized trial that compared first-line vasoactive drugs in children with septic shock. Sequential bSSS and cSSS from 60 children (single-center study, 53% mortality) were analyzed. The prognostic value of the ESPNIC RSS definition was tested for 28-day all-cause mortality. Results In this septic shock cohort, RSS was diagnosed in 35 patients (58.3%) during the first 24 h. Death occurred in 30 RSS patients (85.7% mortality) and in 2 non-RSS patients (8% mortality), OR = 60.9 [95% CI: 10.5–676.2], p < 0.001 with a median delay from sepsis onset of 3 days [1.0–6.7]. Among patients diagnosed with RSS, the mortality was not significantly different according to vasopressors randomization. Diagnosis of RSS with bSSS and cSSS had a high discrimination for death with an area under the receiver operating curve of 0.916 [95% CI: 0.843–0.990] and 0.925 [95% CI: 0.845–1.000], respectively. High prognostic accuracy of the bSSS was found in the first hours following intensive care admission. The best interval of prognostication occurs after the 12th hour following treatment initiation (AUC 0.973 [95% CI: 0.925–1.000]). Conclusions The ESPNIC refractory septic shock definition accurately identifies, within the first 6 h of septic shock management, children with lethal outcome.
