2 Valutazione della gravità
Riconoscimento che qualche cosa non va alterazione del sensorio dispnea, tachipnea, alterazione della meccanica-dinamica ventilatoria SpO2 alterazione della PA tachicardia, aritmia contrazione della diuresi  T° alterazione degli esami ematochimici ecc. quanto sopra + iper-ipotermia / leucocitosi-leucopenia infezione Che fare di fronte ai segnali d’allarma che ho indicato precedentemente? Una delle cose da fare, anche se il quadro clinico (anamnesi + es.obiettivo) ci inducono a ritenere presente un quadro di sepsi, sepsi grave o, peggio, shock settico, è ricordare che esistono altre patologie che possono mimare tali quadri (anche perché ne condividono parte della patogenesi)(v dia successiva) Quanto non va ?

9 Special admission paths: sepsis
R Ferrer, A.Navas, ML Martinez, A.Artigas The key to success involves the implementation of a hospital wide system that recognizes septic patients early, and at the same time rapidly administers effective therapy ( sepsis-rapid response team)(?) The results of the meta-analysis are very consistent in showing that sepsis bundles improve survival by improving the way sepsis treatments are delivered Health care organizations traditionally favour investing in new technology and drugs, but are reluctant to invest in organizational development. For sepsis care bundles to succeed, this must change elementi del bundle probabilmente correlati a sopravvivenza: antibioticoterapia, rapido riconoscimento della sorgente d’infezione, volemia e pressione, supporto respiratorio, proteina C attivata (?), controllo della glicemia (?)

11 Immunoinflammatory response of three hypothetical patients
Immunoinflammatory response of three hypothetical patients with sepsis. The individual immune response in sepsis is determined by many factors, including pathogen virulence characteristics, size of the bacterial inoculum, patient comorbidities. The initial immune response is hyperinflammatory, but the response rapidly progresses to hypoinflammatory. In the healthy individual who experiences meningococcemia, there is a robust hyperinflammatory response. Death may occur rapidly because of a hyperinflammatory state, and antiinflammatory treatments may improve survival. If infection resolves, there is only a minimal hypoimmune state. In the elderly patient with malnutrition who experiences diverticulitis, the initial response is limited, and if the infection persists, a prolonged hypoinflammatory response develops, followed by recovery or death. In the patient with diabetes, chronic renal failure, and pneumonia, the initial response is blunted, and there is a prolonged depression of immune function.

18 Cardiac conditions considered to increase a patient’s risk of developing infective endocarditis, i.e. ‘at risk’ heart valve lesions.

19 The endocarditis risk in GUCH patients is substantially higher than in the general population, with marked variation between lesions. It has to be emphasized that good oral hygiene and regular dental review have an essential role in reducing the risk of IE. Aseptic measures are mandatory during manipulation of venous catheters and during any invasive procedure in order to reduce the rate of healthcare-associated IE. GUCH patients should also be discouraged from getting piercings and tattoos.

20 The approach to antibiotic endocarditis prophylaxis has changed for several reasons.
In short, transient bacteraemia occurs not only after dental procedures but frequently in the context of daily routine activities such as tooth brushing, flossing, or chewing. Due to the lack of scientific evidence for the efficacy of antibiotic prophylaxis, the estimated huge number of patients that may need to be treated to prevent one single case of IE, the small but existing risk of anaphylaxis, and the general problem of emergence of resistant microorganisms resulting from widespread, often inappropriate use of antibiotics, it is currently recommended by expert consensus to limit antibiotic prophylaxis to patients with the highest risk of IE undergoing the highest risk procedures (IIaC).

21 This recommendation includes the following patient groups:
Patients with a prosthetic valve or a prosthetic material used for cardiac valve repair Patients with previous IE Patients with CHD: a cyanotic CHD, without surgical repair, or with residual defects, palliative shunts, or conduits a CHD after repair with prosthetic material whether placed by surgery or by percutaneous technique, up to 6 months after the procedure (until endothelialization) a when a residual defect persists at the site of implantation of a prosthetic material or device by cardiac surgery or percutaneous technique. The recommendation is limited to dental procedures requiring manipulation of the gingival or periapical region of the teeth or perforation of the oral mucosa. Antibiotics are not recommended for respiratory tract, gastrointestinal, genitourinary, dermatological, or musculoskeletal procedures unless there is an established infection.

27 Steroids ◦ Consider intravenous hydrocortisone for adult septic shock when hypotension remains poorly responsive to adequate fluid resuscitation and vasopressors. (2C) ◦ ACTH stimulation test is not recommended to identify the subset of adults with septic shock who should receive hydrocortisone. (2B) ◦ Hydrocortisone is preferred to dexamethasone. (2B) ◦ Fludrocortisone (50μg orally once a day) may be included if an alternative to hydrocortisone is being used which lacks significant mineralocorticoid activity. Fludrocortisone is optional if hydrocortisone is used. (2C) ◦ Steroid therapy may be weaned once vasopressors are no longer required. (2D) • Hydrocortisone dose should be ≤300 mg/day. (1A) • Do not use corticosteroids to treat sepsis in the absence of shock unless the patient’s endocrine or corticosteroid history warrants it. (1D) Strength of recommendation and quality of evidence have been assessed using the GRADE criteria, presented in brackets after each guideline. For added clarity: • Indicates a strong recommendation or “we recommend”; ◦ indicates a weak recommendation or “we suggest” CIRCI = Critical Illness-related corticosteroid insufficiency

28 Nov.2008 Steroids Negli ultimi anni l’uso dei corticosteroidi nello shock settico è risultato controverso Pro: miglioramento emodinamico con più rapida sospensione dei vasopressori > rapidità di risoluzione della disfunzione d’organo < mortalità (?)

Recommendations for the diagnosis and management of corticosteroid insufficiency in critically ill adult patients: Consensus statements from an international task force by the American College of Critical Care Medicine Crit Care Med 2008; 36:1937–1949 Recommendation 6: Hydrocortisone should be considered in the management strategy of patients with septic shock, particularly those patients who have responded poorly to fluid resuscitation and vasopressor agents. Strength of Recommendations: 2B

31 Corticosteroids in the Treatment of Severe Sepsis and Septic Shock in Adults Annane D, Bellissant E, Bollaert PE, et al. JAMA. 2009; 301: 28-day mortality was modestly reduced (relative risk [RR] = 0.84, P = .05) and was also modestly reduced in the subset of studies reporting prolonged corticosteroid administration (RR = 0.84, P = .02). Treatment increased the proportion of patients achieving reversal of shock and reduced the length of intensive care unit stay without a detectable increase in gastrointestinal bleeding, superinfection, or neuromuscular complications. Corticosteroids did increase the risk for hyperglycemia and hypernatremia. The authors concluded that the prolonged use of corticosteroids safely reduces short-term mortality in patients with severe sepsis or septic shock. Until a definitive clinical trial answers this question, corticosteroid use will continue to be highly variable and at the discretion of intensivists worldwide metaanalisi

32 Conclusions: Based on clinically meaningful thresholds (RRR[15–25%) for mortality reduction in severe sepsis or septic shock, the Bayesian approach to all three meta-analyses consistently showed that low-dose steroids were not associated with survival benefits. The probabilities of developing steroid- induced side effects (superinfections, bleeding, and hyperglycemia) were high for all analyses.

33 R. Moreno C. L. Sprung D. Annane S. Chevret J. Briegel D. Keh M. Singer Y. G. Weiss D. Payen B. H. Cuthbertson J.-L. Vincent Conclusion Patients randomized to treatment with hydrocortisone demonstrated a faster decrease in total organ dysfunction/failure determined by the SOFA score, primarily driven by a faster improvement in cardiovascular organ dysfunction/failure. This organ dysfunction/failure improvement was not accompanied by a decreased mortality.

Note that this technique is different from the previous technique in that we use plasma instead of ultrafiltrate and a much greater quantity of resin. UF out Reinfusate in

35 CPFA used successfully in non-ARF patients
Hemodynamic response to coupled plasmafiltration-adsorption in human septic shock Marco Formica, Carlo Olivieri, Sergio Livigni, Giulio Cesano, Antonella Vallero, Mariella Maio and Ciro Tetta Intensive Care Med (2003) 29: Objective: The objective was to examine the effect of repeated applications of coupled plasmafiltration-adsorption on the hemodynamic response in septic shock patients hospitalized in intensive care units (ICUs). entusiati Conclusion: Coupled plasmafiltration-adsorption was a feasible and safe extracorporeal treatment and exerted a remarkable improvement in the hemodynamics, the pulmonary function, and the outcome in septic shock patients with or without concomitant ARF.

36 Anne-Corne´lie J. M. de Pont, MD, PhD Adult Intensive Care Unit Academic Medical Center University of Amsterdam Amsterdam, The Netherlands …The improvement of blood purification techniques and membranes has generated new opportunities for the use of extracorporeal techniques in sepsis. Removal of both pro- and anti-inflammatory mediators by means of these new techniques is feasible and might add to the restoration of homeostasis by controlling excessive cytokine production (the so-called peak concentration hypothesis). Whether this approach will result in a better clinical outcome for patients with severe sepsis remains to be investigated. più prudenti da definire: metodica, tipologia di filtri utilizzati, volumi trattati, tempo di applicazione
