MERS

Middle East respiratory syndrome coronavirus (MERS-CoV)

MERS is classified as a High Consequence Infectious Disease (HCID), and although unlikely is serious and could be imported into the UK at ANY time. Risks are higher when there is increased travel to endemic areas such as Hajj.

Symptoms include fever and cough that progress to a severe pneumonia causing shortness of breath and breathing difficulties. In some cases, a diarrheal illness has been the first symptom to appear.

UK Health Security Agency:

Suspected = Isolate & Full PPE

  • Trust Guidance
  • PPE Notes:
    • FFP3 (can’t use hoods)
    • Buddy System vital
  • Senior Review needed
    • Collect relevant information
    • Contact Microbiologist immediately (as may de-escalate without tests)

SITE Specifics

HRI:

  • Primary site for Pre-alerts
  • 1 Patient – goes to Isolation. room
  • 2 Patients  – second patient goes to Minors 5
    • end of corridor and lounge closed off
  • 3+ Patients – ALL MERS patients moved to Minors Corridor
    • Minors corridor closed
    • Minors/UCH moved to uSDEC
    • Internal Trust Majax

Think -TB

The prevalence of Tuberculosis in our region is increasing and has significant issues for both the patient and public health if we miss it.

Symptoms

  • Cough
  • Fever
  • Night Sweats
  • Lymphadenopathy
  • Weight loss

High-Risk factors to consider

Characteristics

  • Previous/Latent TB
  • TB Contact
  • Immunocompromised
  • Substance Misuse
  • Homeless/Prision
  • Pubs – esp. Vulcan Hudds

Travel/Ethnicity

  • Eastern Europe
  • India/Pakistan
  • East Asia
  • Africa

CXR Changes

  • Upper Lobe Consolidation
  • Hilar Lymphadenopathy
  • Cavities

Actions

  • Provide 3 AFB samples – Ideally performed in ED/Ward (but if patient fit for discharge and unable provide samples in ED give patient pots and request which they return to their GP.
  • Don’t Commence TB treatment – unless instructed by respiratory team
  • If admitted isolation requested
  • If discharged Patient told to isolate and if must go into public wear face mask
  • Contact TB team:
    • Huddersfield/Halifax – Based on GP postcode
    • In-Hours: either through Switch board or as EPR referral
    • Out of Hours: Though EPR referral
    • They will ensure appropriate notification of Public Health

Huddersfield

  • Dr Anneka Biswas
  • Chantelle Lashington
  • Deborah Howgate

Halifax

  • Dr Nicholas Scriven
  • Mary Hardcastle

LA – Toxicity

We are regularly doing blocks next to major vessels. So warn the patient of the symptoms, & keep them monitored(at least 15 min).

Symptoms of local anaesthetic toxicity

  • Circumoral and/or tongue numbness
  • Metallic taste
  • Lightheadedness/Dizziness
  • Visual/Auditory disturbances (blurred vision/tinnitus)
  • Confused/Drowsiness/Fitting
  • Arrhythmia
  • Cardio-Resp Arrest

Remember – Do basics WELL

Without Cardio-Resp Arrest

Use conventional therapies to treat:

  • Seizures
  • Hypotension
  • Bradycardia
  • Tachyarrhythmia (Lidocaine should not be used as an anti-arrhythmic therapy)

In Cardio-Resp Arrest

  • CPR – using standard protocols (Continue CPR throughout treatment with lipid emulsion)
  • Manage arrhythmias – using standard protocols
  • Consider the use of cardiopulmonary bypass if available
  • Recovery from LA-induced cardiac arrest may take >1 h
  • Lidocaine should not be used as an anti-arrhythmic therapy

Malignant/Accelerated Hypertension

There are several terms commonly used “Accelerated Hypertension”, “Hypertensive Emergency”, “Malignant Hypertension”. They all have a very similar definition (ESC/ESH, NICE, ACEP)

Patient has both:

  1. Blood pressure: Systolic ≥180mmHg OR Diastolic ≥110mmHg (often >220/120mmHg)
  2. End-Organ Damage: Retinal Changes, Encephalopathy, Heart Failure, Acute Kidney Injury, etc.

Mortality has improved in recent years with 5yr survival of 80% if treated. However, untreated average life expectancy is 24 months.

Acute Behavioural Disturbance / Excited Delirium

Most of us will have seen patients like this – agitated, aggressive and often with police or security pinning them down.

  1. High risk of Cardiovascular Collapse/Death – likely due to adrenaline surge, heat exhaustion and injury. It can happen very suddenly.
  2. Keep physical restraint to a minimum – Don’t allow patient to forced face down, it’s the most likely way of killing them.
  3. Sedation – if you’re restraining you will almost certainly need to sedate. IV is best but if access is too risky IM will have to do.
  4. Aggressive management of underlying issues – esp. hyperthermia and acidosis and look out for rhabdomyolysis and DIC

Trust Guide

Acute Heart Failure (AHF) – ESC

Patients presenting with AHF have a high mortality 4-10% in-hospital and 25-30% at 1yr, and 45% if re-admitted. So rapid diagnosis a treat is essential.

AHF Triggers

there are many triggers for AHF, which if recognized and treated with help improve outcomes

  • Cardiac: ACS, Arrhythmia, Aortic Dissection, Acute Valve Incompetence, VSD, Malignant Hypertension
  • Respiratory: PE, COPD
  • Infection: Pneumonia, Sepsis, Infective endocarditis
  • Toxins/Drugs: Alcohol, Recreational drugs, NSAIDs, Steroids, Cardiotoxic meds
  • Increased Sympathetic Drive: Stress
  • Metabolic: DKA, Thyroid dysfunction, Pregnancy, Adrenal Dysfunction
  • Cerebrovascular Insult

ESC Guide – 2021 Heart Failure

Presentations

Decompensated Heart Failure

Isolated Right Vent-Failure

Pulmonary Oedema

Cardiogenic Shock

Managment

Treatment – Time Matters!!!

  • Mortality increased by 1%/hour IV treatment not started

Treat The Cause!: If you can identify the trigger treat it it will in turn improve the AHF. (e.g. AMI, Arrythmia(Tachy/Brady), Massive PE)

Oxygen
  • Not all patients should be given Oxygen ESC suggest maintain SaO2 >90%
  • Early NIV is suggested if any of:
    • RR >25bpm or SaO2 <90% despit oxygen
    • Signs type 2 respiratory failure

Metanalysis suggests early NIV may reduce need for intubation and improve mortality
