This document defines sepsis and related conditions like septic shock. It discusses signs and symptoms, risk factors, investigations and treatments. Sepsis is defined as a systemic inflammatory response due to infection. Septic shock involves hypotension despite fluid resuscitation. Common causes are bacterial infections. Treatments include antibiotics, fluid resuscitation, vasopressors and source control through removal of infected lines or drainage of abscesses. Prognosis is assessed using scores like SOFA that evaluate organ dysfunction severity.
It includes new definition, pathophysiology, management of sepsis, septic shock and neutropenic sepsis and even newer evolving concepts or types of sepsis.

I'm barely responsible for compilation of various resources per my interest. These resources are free for use, and I do not claim any copyright. Hoping knowledge remains free for all, forever.
It is the first kind of cases that I had to learn to manage. The cases ere so abundant and management so rapid that it took me a while to wrap my head around it. I did not sepsis from septic shiock, I did not know the signs and symptoms and I definitely did not how it all came together. Sepsis bundles included in the presentation need to be updated.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

4. DEFINITONS
• Bacteremia :presence of bacteria in blood,as evidenced
by positive blood culture
• Septicemia: presence of microbes or their toxins in blood
5. SIRS
• Systemic inflammatory response syndrome: defined by
the presence of two or more of the following
1. tachypnea : RR>20 breaths/min or PaCO2<32mmHg
2. WBC count<4000 cells/µL or >12000 cells/µL
3. Tachycardia: pulse>90 beats/min
4. Hypo or hyperthermia : temp>38°c or <36°c
6. • In 2016, SIRS was replaced with a shortened sequential
organ failure assessment score(SOFA score) known as
the quick SOFA score(qSOFA)
The score ranges from 0 to 3 points.
The presence of 2 or more qSOFA points near the onset of
infection is associated with a greater risk of death or
prolonged intensive care unit stay.
Assesment qSOFA score
Low blood pressure(SBP≤100mmHg) 1
High RR(≥22breaths/min) 1
Altered mental status(GCS≤14) 1
8. SEVERE SEPSIS
• Sepsis with one or more signs of organ dysfunction
1. CVS: arterial SBP≤90 mmHg or mean arterial BP ≤70
mmHg that responds to administration of iv fluid
2. Renal: urine output <0.5 ml/kg per hour for 1 h despite
adequate fluid resuscitation
3. Respiratory: PaO2/FiO2 ≤250 or, if the lung is only
dysfunctional organ ,≤200
4. Hematologic: platelet count <80000/µL or 50%
decrease in platelet count from highest recorded over
previous 3 days
5. Unexplained metabolic acidosis ;ph ≤7.30 or base
deficit ≥5 mEq/L and plasma lactate level >1.5 times
upper limit of normal for reporting lab
9. SEPTIC SHOCK
• Sepsis with hypotension(arterial SBP<90 mmHg or 40
mmHg less than patients normal BP) for at least 1 h
depite adequate fluid resuscitation
• OR
• Need for vasopressor to maintain SBP≥90 mmHg or
MAP ≥70mmHg
• Stages :
a) Hyperdynamic(warm) shock
b) Hypodynamic (cold) shock
10.
11. CAUSES
• Infections leading to sepsis are usually bacterial, but may
be fungal or viral.
• gram-positive bacteria, most commonly staphylococci,are
thought to cause more than 50% of cases of
sepsis.(enterococci, streptococcus pneumoniae)
• Gram negative bacteria such as enterobacteriaceae,
pseudomonads, haemophilus spp
• Fungal sepsis accounts for approximately 5% of severe
sepsis and septic shock cases; the most common cause of
fungal sepsis is infection by Candida species of yeast,
15. • It is important to identify any potential source of infection.
Localizing signs and symptoms referable to organ
systems may provide useful clues to the etiology of
sepsis and are as follows:
• Head and neck infections – Severe headache, neck
stiffness, altered mental status, earache, sore throat,
sinus pain/tenderness, cervical/submandibular
lymphadenopathy
16. • Chest and pulmonary infections – Cough (especially if
productive), pleuritic chest pain, dyspnea, dullness on
percussion, bronchial breath sounds, localized rales, any
evidence of consolidation
• Cardiac infections – Any new murmur, especially in
patients with a history of injection or IV drug use
17. • Abdominal and gastrointestinal (GI) infections –
Diarrhea, abdominal pain, abdominal distention,
guarding or rebound tenderness, rectal tenderness or
swelling
• Pelvic and genitourinary (GU) infections – Pelvic or
flank pain, adnexal tenderness or masses, vaginal or
urethral discharge, dysuria, frequency, urgency
18. • Bone and soft-tissue infections – Localized limb pain
or tenderness, focal erythema, edema, swollen joint,
crepitus in necrotizing infections, joint effusions
• Skin infections – Petechiae, purpura, erythema,
ulceration, bullous formation, fluctuance
19. SOFA SCORE
• The SOFA scoring system is useful in predicting the
clinical outcomes of critically ill patients
• RESPIRATORY system:
PaO2/FiO2 (mmHg) SOFA score
≥ 400 0
< 400 +1
< 300 +2
< 200 and mechanically ventilated +3
< 100 and mechanically ventilated +4
27. • Cultures:(pus, blood, urine)
• To identify the causative organism(s), at least two sets
of blood cultures using bottles
with media for aerobic and anaerobic organisms should
be obtained, with at least one drawn through the
skin and one drawn through each vascular access
device (such as an IV catheter) in place more than 48
hours.
28. • Imaging modalities:
• Chest radiography to rule out pneumonia and diagnose
other cause of pulmonary infiltrates
• Abdominal USG
• Abdominal CT or MRI for assessing a suspected
nonbiliary intra abdominal source of infection or
delineating intrarenal and extrarenal pathology
29. • Invasive diagnostic procedures:
• Thoracocentesis(in patient with substantial pleural
effusion)
• Paracentesis(in patients with gross ascites)
30. TREATMENT OF SEVERE SEPSIS/SEPTIC
SHOCK
1. Volume resuscitation
2. Cardiovascular supports
3. Antimicrobial therapy
4. Source control
5. Early goal directed therapy
6. Surgery
31. VOLUME RESUSCITATION
• Iv access with 2 wide bore cannulas are secured
• Patient should initially receive 30mL/kg iv crystalloid fluid
within first hour of presentation
• Then re-assess, and repeat as appropriate
• Urethral catheter is passed to empty the bladder then to
monitor the hourly urine output(30-50ml/hr)
• Central venous catheter is inserted(10-15cmH20)
32. RESPIRATORY SUPPORT
• Supplemental oxygen should be administered to all
patients with suspected sepsis.
• Early intubation and mechanical ventilation should be
strongly considered for patients with any of the following:
• Oxygen requirement
• Dyspnea or tachypnea
• Persistent hypotension
• Evidence of poor peripheral perfusion
33. CORRECTION OF ANEMIA AND
COAGULOPATHY
• if hemoglobin levels fall below 7 g/dL, red blood cell
(RBC) transfusion is recommended to a target
hemoglobin range of 7-9 g/dL
• Platelet transfusion may also be considered when
bleeding risk is increased and platelet counts are below
20 × 109/L (20,000/µL).
34. CARDIOVASCULAR SUPPORT
• If the patient does not respond to resuscitation with
several liters (usually ≥4 L) of isotonic crystalloid solution
or if evidence of volume overload is present, the
depressed cardiovascular system can be stimulated by
means of vasopressor therapy.
• First-line agents: Norepinephrine,dopamine
• Norepinephrine has predominant alpha-receptor agonist
effects and results in potent peripheral arterial
vasoconstriction without significantly increasing heart
rate or cardiac output.
35. • The dosage range for norepinephrine is 5-20 µg/min,
and it is not based on the weight of the patient.
• Norepinephrine is preferred to dopamine for managing
septic shock because dopamine is known to cause
unfavorable flow distribution (more arrhythmias). In this
setting, norepinephrine has been shown to be both
significantly safer and somewhat more effective.
36. • Dopamine: is used only in certain highly specific
situations, such as when there is a low risk of
tachyarrhythmias and in the presence of coexistent
bradycardia.
• Treatment usually begins at 5-10 µg/kg/min IV, and the
infusion is adjusted according to the blood pressure and
other hemodynamic parameters.
38. ANTI MICROBIAL THERAPY
• Agents suitable for empiric monotherapy regimens may
include the following:
• Imipenem
• Meropenem
• Tigecycline
• Piperacillin-tazobactam
• Ampicillin-sulbactam
• Moxifloxacin
39. IMMUNOCOMPETENT ADULT
• If no obvious source:
(1) piperacillin-tazobactam (3.375 g q4–6h)
(2) imipenem-cilastatin (0.5 g q6h), ertapenem (1 g q24h),
or meropenem (1 g q8h)
(3) cefepime (2 g q12h
(4) If the patient is allergic to β-lactam agents, use
ciprofloxacin (400 mg q12h) or levofloxacin (500–750 mg
q12h) plus clindamycin (600 mg q8h).
(5) Vancomycin (15 mg/kg q12h) should be added to each
of the above regimens if there is high prevalence of
MRSA
40. • If urosepsis:
• aerobic gram-negative bacilli employs aztreonam,
levofloxacin, a third- or fourth-generation cephalosporin,
or an aminoglycoside.
• urosepsis due to enterococci (E faecalis) involves the
use of ampicillin or vancomycin (penicillin-allergic).
41. • In case of iv drug user
Vancomycin (15 mg/kg q12h) is essential
• In case of AIDS: Cefepime alone (2 g q8h) or
piperacillintazobactam (3.375 g q4h) plus tobramycin (5–
7 mg/kg q24h) should be used.
• If the patient is allergic to β-lactam drugs, ciprofloxacin
(400 mg q12h) or levofloxacin (750 mg q12h) plus
vancomycin (15 mg/kg q12h) plus tobramycin should be
used.
42. • Treatment duration is typically 7–10 days with the type of
antibiotic used directed by the results of cultures.
• If the culture result is negative, antibiotics should be de-
escalated according to person's clinical response or
stopped altogether if infection is not present
43. REMOVAL OF THE SOURCE OF
INFECTION
• Sites of occult infection should be sought carefully,
particularly in the lungs, abdomen, and urinary tract.
• Indwelling IV or arterial catheters should be removed
• Foley and drainage catheters should be replaced
44. EARLY GOAL DIRECTED THERAPY
• is an approach to the management of severe sepsis
during the initial 6 hours after diagnosis
• involves monitoring of hemodynamic parameters and
specific interventions to achieve key resuscitation targets
which include maintaining a central venous pressure
between 8–12 mmHg, a mean arterial pressure of
between 65–90 mmHg, a central venous oxygen
saturation (ScvO2) greater than 70% and a urine output
of greater than 0.5 ml/kg/hour
45.
46. SURGERY
• Patients with focal infections should be sent for definitive
surgical treatment after initial resuscitation and
administration of antibiotics
• Certain conditions will not respond to standard treatment
for septic shock until the source of infection is surgically
removed
47. • for example:
• intra-abdominal sepsis (perforation, abscesses),
empyema, mediastinitis, cholangitis, pancreatic
abscesses, pyelonephritis or renal abscess from ureteric
obstruction, infective endocarditis, septic arthritis,
infected prosthetic devices, deep cutaneous or perirectal
abscess, and necrotizing fasciitis.
