What are the three types of Influenza? Which ones cause illness?
A, B, C
A&B cause illness
What are the two types of Flu-vaccine and what groups of patients are they given to?
Live, intranasal vaccine (to children)
Inactivated, injectable (to at risk groups)
What are contraindications to giving the live, intranasal vaccine to children?
- If Immunocompromised
- If aged <2 years old
- Current febrile illness / blocked nose / rhinorrhoea
- Current wheeze or history of severe asthma
- Egg allergy
- If child is taking aspirin (e.g. for Kawasaki’s Disease) due to a risk of Reye’s syndrome
What does the Inactivated, injectable form of Influenza given to at risk groups consist of?
- Trivalent, consist of two subtypes of influenza A and one subtype of influenza B
What are the indications of giving the Inactivated, Injectable form of Influenza to at risk groups?
- All people over the age of 65 years old
- All people over the age of 6 months plus the following:
- Chronic respiratory disease, including asthmatics who use steroids
- Chronic heart disease (heart failure, ischaemic heart disease, including hypertension if associated with cardiac complications)
- Chronic kidney disease
- Chronic liver disease: cirrhosis, biliary atresia, chronic hepatitis
- Chronic neurological disease: (e.g. Stroke/TIAs)
- Diabetes mellitus (including diet controlled)
- Immunosuppression due to disease or treatment (e.g. HIV)
- Asplenia or splenic dysfunction
- Pregnant women
- Adults with a body mass index >40 kg/m²
- Health and social care staff directly involved in patient care
- Those living in long-stay residential care homes
- Carers of the elderly or disabled person whose welfare may be at risk if the carer becomes ill
What are the contraindications for the Inactivated, Injectactable Influenza vaccine?
Egg protein allergy
When is Tetanus offered to children?
At five points in their life:
- 2 months, 3 months, 4 months, 4-5 years, and 13-18 years
A patient has high risk wounds, give examples of such wounds?
What would you give?
- Wounds: Compound fractures, delayed surgical intervention, necrotic tissue
- Treatment: IM Human Tetanus Immunoglobulin
If patient has a high risk wound, and no vaccination history, what would you give?
A dose of tetanus vaccine plus intramuscular human tetanus immunoglobulin
What is Sepsis defined as?
A syndrome that occurs when an infection causes a patient to become systemically unwell due to a severe systemic inflammatory response (SIRS)
What is the pathophysiology of Sepsis?
- Pathogens recognised bymacrophages,lymphocytesandmast cells → Releaseof cytokines
- Cytokinesincrease blood vessel permeability → Fluid leakage intoextracellular space →Oedema + a reduction inintravascular volume. Oedema reduces oxygen to tissues
- Cytokines cause further release of chemicals i.e.NO→vasodilation
- Activation of coagulation system→ Fibrin deposition compromising organ and tissue perfusion. Platelet + clotting factor consumption as more blood clots form →Thrombocytopenia,haemorrhagesand an inability to form clots and stop bleeding → Disseminated Intravascular Coagulopathy(DIC)
- Anaerobic respirationin the hypo-perfused tissues → Increased lactate
What is Septic Shock?
When Sepsis → Cardiac dysfunction. Arterial BP falls → Hypoperfusion. This also causes anaerobic respiration and a rise in blood lactate
What things are assessed regarding the Traffic Light System for Sepsis?
Traffic Light System: Colour, Activity, Respiratory Rate, Circulation & Hydration, and Other
How is Septic Shock managed?
Manage as Sepsis plus:
- Aggressive IV Fluid therapy → Improves BP and tissue perfusion
- If IV Fluid fails → ITU/HDU admission, consider inotropes i.e. noradrenaline to stimulate CVD
How is Neonatal Sepsis Categorised?
- Early onset → First 72 hours of life
- Late onset → From Day 7-28 of life
What are common causes of Neonatal Sepsis in:
Early onset Sepsis
Late onset Sepsis
- Early onset: Group B Streptococcus
- Late onset: Staphylococcus epidermidis, Pseudomonas aeruginosa, Klebsiella and Enterobacter, and fungal species
What are risk factors for Neonatal Sepsis?
- Mother who has had a previous baby with GBS infection
- Mother who hascurrent GBS colonisationfrom prenatal screening, current bacteruria, intrapartum temperature ≥38ºC, membrane rupture ≥18 hours, or current infection throughout pregnancy
- Premature (<37 weeks)
- Low birth weight (<2.5kg)
- Evidence of maternal chorioamnionitis
What is the antibiotic of choice for Neonatal Sepsis according to NICE Guidelines?
Benzylpenicillin with Gentamicin
What is Meningitis?
Inflammation of the meninges, which are linings of the brain and spinal cord usually caused by a bacterial or viral infection
