Pulmonary Embolism in Pregnancy

Unfortunately the the normal pathway for investigation of PE performs poorly in pregnancy RCOG have the following pathway

1. Investigation – of suspected PE

  • Clinical assessment – its all on the history and exam scoring doesn’t work
  • Perform the following tests:
    • CXR – sheilding can protect the baby and may avoid further radiation
    • ECG
    • Bloods: FBC, U&E, LFTs, Clotting
  • Commence Tinzaparin (unless treatment is contraindicated – use booking weight to calculate dose) –[BNF]

 

VTE prophylaxis in lower limb Immobilisation (ED – 2023)

In the Emergency Department (ED) lower leg immobilisation after injury is a necessary treatment but is also a known risk factor for the development of venous thromboembolism (VTE). This accounts for approximately 2% of all VTE cases which are potentially preventable with early pharmacological thromboprophylaxis.

RCEM – Frailty in the ED

As we all know frailty and care of older patients is becoming a more and more important in the ED. The elderly population is growing rapidly and as you age your health costs shoot up.

The study day not only highlighted several import areas of care within ED, but also how relatively small interventions/conversations can make significant differences.

  1. Think Home First:
    • What is stopping them going home?
    • What tests will guide your decision making? (don’t just investigate because you can)
    • Get them up (you don’t need to wait for physios)
  2. Do the easy stuff: Feed, Water, Toilet, Communicate
  3. DON’T create barriers: e.g. catheters, exessive testing
  4. Ask for help: Local service are your friend

Population & Costs

Increasing aging population:

Costs as we age:

Life Expectancy

Life Expectancy:

Average life expectancies are often longer than you imagine and after 100yrs life expectancy increases!

  • 80yr woman – 10yr
  • 85yr woman – 7yr
  • 90yr woman – 5yr
  • 99yr woman – 2yr

However, Clinical frailty score is often more predictive.

 

Frailty Trajectory and Life Expectancy

Study shows that the rate of change in frailty has a significant impact on life expectancy. People with “Stable” growth in frailty score remaining at their base line but the faster the CFS changes more impact that has. 

So its worth asking how things have changed over the last year.

Trauma

Frailty has a significant influence on recovery and mortality in relation to both “MINOR” and “MAJOR” trauma. 

 

Rib injury is probably more important than most of us realise – suggesting 15% increase in mortality for every rib a frail person fractures.  JRCALC have since updated guidance to recommend “rib spring” rather than “gentle palpation” in examination.

Silver Trauma Review Clinic:

Mater hospital Dublin have introduced a review clinic for patients following significant traumas.

Mater hospital – Adult only ED

  • 90’000 attendances/yr
  • 10.5WTE ED consultants
  • Major Trauma Centre

Silver Trauma Review Clinic

  • Weekly clinic sees 10 patients/week
  • Follows up: trauma patients discharged with non-operative management or post admission
  • Team: EM, Geris, Frailty ACP, Physio
  • Main work: Thoracic, Spinal, humeral, pelvic injuries
  • Requires access to DEXA and MRI (they MRI all spinal injury through clinic not only to age but also find other diagnosis)
  • Reduced admissions.
  • EMJ
Syncope

A really common presentation elderly patients that can be tricky with a higher baseline probability of cardiac causes.

80% is on the history:

  • However, both memory of events & prodromal symptoms are often reduced in older patients
  • Look for causes “What was different that day”
  • Witnesses are really important – the elderly will tend to down play and may confabulate if memory is an issue

Investigation:

sBP takes longer to improve after standing as you get older. Recovery in <45s tends to be good.
  • Heart sounds – Murmurs
  • Neurological 
  • LSBP
  • Bloods inc BM
  • ECG
  • Get up and Go – to look at gate etc.

Get up and Go test

Causes – the frail often have more than 1

  • Orthostatic Hypotension
    • Drugs, Drugs, DRUGS
    • Volume
    • Autonomic failure: Diabetes, Amyloid, PD, Adrenal insuf etc..
    • Alcohol

 

 

  • Reflex (neurally mediated)
    •  
    • Vasovagal
    • Situational – cough, micturition, post exercise, eating
    • Carotid sinus Syndrom
  • Cardiac Arrhythmia
    • Sinus node, AV conduction, Tachy, device malfunction, inherited
    • ALWAYS interrogate devices if they have one
  • Structural Heart Disease
    • Is there a murmur?

Syncope Pathway – Reduces LoS

Delirium

4AT = NEWS for the Brain

 We miss Delirium in 50% of cases & when we do miss it we are 70-80% confident that we were right – so use 4AT 

 

Then PINCH-ME

We often over test look for the simple things first they are the most common.

End of Life

“Wasting a dying persons remaining time is WRONG”

Most patients would prioritise time with love ones rather than fruitless time with us.

Recognise

  • History: CFS, co-morbidities, exersize tolerance, ADL’s Residential status
  • Trends/Trajectories: what has happened since arrival and what has happened ob=ver the last few months?
  • Differential diagnosis: what is the prognosis and are the treatments desirable?

Outcomes

Emergency Laparotomy: CFS is more predictive than age

 

Covid:

 

In-hospital CPR: frailty can predict outcome in UK trial

 

Do Not Resuscitate Decisions  

Ombudsman states: End of Life

  • “Decisions about not resuscitating a patient, or about putting a DNACPR notice on a patient’s record, are made by doctors and do not need patient consent. This can be an immediate clinical decision made when a patient is seriously unwell, or a decision that goes on a patient’s records in advance and affects treatment at a later stage. But it is a legal requirement for doctors to consult with a patient about a DNACPR decision if they have capacity, and with their next of kin otherwise.”

But our communication needs to be clear to patients and families, not just saying “they are sick” but how sick. And not just what we are not going to do but what we are going to do for the patient.

Preparation:

  • Ensure Anticipatory Medication prescribed
  • End of Life trolly (Dandilion trolly – QLD)
    • Syringe driver kit
    • Paperwork
    • Black towels – to hide blood loss (reduces distress)
    • Taste for pleasure – mouth care with things people actually like (families can bring)

Bell’s Palsy

Bell’s Plays is a lower motor neurone (LMN) lesion of the facial nerve (CN VII), which causes one side of the face to “droop” [1% of cases are bilateral], and patients are often concerned that it is a stroke.

However, unlike in stroke the whole face is affected, in stroke and other upper motor neurone (UMN) lesions the upper portion of the face is unaffected due to input from both sides of the brain. Read more

Hypoglycaemia – Adult

Hypoglycaemia (Blood glucose under 4.0 mmol/l) is potentially fatal and should be treated. it may be defined as “mild” self-treated, or “severe” treated by a third party i.e. you.

Hypoglycaemia is a common side-effect of insulin and sulfonylureas (they start with gli-) as they both work by lowering glucose concentration in the blood. Other diabetic medications work by preventing glucose rise, thus posing a lesser risk.

 

Signs & Symps

  • Autonomic: Sweating, Palpitations, Shaking, Hunger
  • Neuroglycopenic: Confusion, Drowsy, Odd behaviour, Incoordination, Speech difficulty
  • General: Nausea, Headache

Risk Factors

  • Medical: 
    • Diabetic: Strict control, Long term Insulin, Lipohypertrophy at injection sites,Impaired awareness of hypoglycaemia
    • Organ dysfunction: Severe hepatic dysfunction, Renal impairment, Cognitive dysfunction/dementia, Endocrine (Addisons, hypothyroid, hypopituitary)
    • GIT: Gastroenteritis, impaired absorption, Bariatric surgery
    • Medication: Concurrent use of medicines with hypoglycaemic agents e.g. warfarin, quinine, salicylates, fibrates, sulphonamides (including cotrimoxazole), monoamine oxidase inhibitors, NSAIDs, probenecid, somatostatin analogues, SSRIs.
    • Sepsis
    • Terminal illness
  • Lifestyle:
    • Reduced/Irregular intake: Poor diet, Irregular lifestyle, Alcohol
    • Increased use: Exercise (relative to usual), Early pregnancy, Breast feeding
    • Poor control: Increasing age, No or inadequate blood glucose monitoring, Alcohol

Treatment

Conscious & Orientated

  1. 15-20g fast acting glucose
    • 4-5 jelly babies
    • 3-4 heaped teaspoons of sugar dissolved in water (milk delays absorption)
    • 150-200ml fresh fruit juice
  2. Rpt Blood Glucose 10-15min
    • if blood glucose remains <4.0mmol/l step one may be repeated up to 3 times in total
  3. Blood Glucose remains <4.0mmol/l
    • 150-200ml 10% Glucose IV
    • 1mg Glucogon IM (if starved or sulfonylureas may not work well)
  4. Blood Glucose >4.0mmol/l – Give long acting Carbs
    • 2 Biscuits
    • 1 Slice bread/toast
    • 200-300ml milk (not soya)
    • Meal
  5. Don’t omit insulin injections
  6. Diabetic review: most patients can be followed up by diabetic nurses but some may need admission.
  7. Patient Advice Sheet

Conscious but agitated, confused, unable to cooperate

  • If patient CAN cooperate – follow guide above
  • If patient CAN’T cooperate
    • 1.5 -2 tubes 40% glucose gel (Glucogel) squeezed into the mouth between the teeth and gums (can be substituted for step 1 above)
    • 1mg Glucogon IM (if starved or sulfonylureas may not work well)
    • Follow subsequent steps as above

Unconscious, seizures, very aggressive

Start at step 3 above (while managing ABC), the choice of whether to use IV glucose or IM glycogen will be determined by practicality of achieving IV/IO access.

Although you will need to follow the remaining steps the patient will almost certainly require admission.

Hypokalaemia

Hypokalaemia (low potassium), is a common problem. It is found in 14% of outpatients and 20% of inpatients, however only 4-5% of those are of clinical significance.

Severity

  • Severe: <2.5 mEq/l OR Symptomatic – Look for Hypomagnesaemia
  • Moderate: 2.5-2.9 mEq/l (No or Minor symptoms)
  • Mild: 3.0-3.4 mEq/l  (Usually asymptomatic)

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
