LVAD – Resus & Troubleshooting

ctsurgerypatients.org

LVADs (Left Ventricular Assist Device) are becoming more common and there are patients in our region with them as a bridge to transplant or recovery and in some cases a destination therapy.

The patient and their family will likely know more about this device than you and should have brought spare parts. Our local LVAD centre is Wythenshaw however, there are other units around the country the patient may direct you to.

The patient may not have a palpable pulse, the blood pressure will be low and the heart pump sounds like a buzz when you listen.

If patient is unresponsive or has a history of collapse its important to troubleshoot the device and resusitation may be required

COPD – exacerbations

COPD patients vary widely, due to their comorbidities, social circumstances, and wishes. So choosing the best treatment pathway for the patient can be complex. Involve senior decision makers.

Questions

  • Is hospital the best place for them?
  • Do they need NIV?
  • Are they dying? – would you want to die surrounded by strangers or with your family?

Asthma – Adult

  • Severity – Severe or Life threatening – think RESUS
  • Treatment within 30 min – bronchodilators and steroids should bee given within 30min
  • 1hrs Observation after Neb – better after a neb don’t just send home they may deteriorate when it wears off.
  • PEFR – must be >75% expected prior to discharge (at least 1hr after treatment finished)
  • Discharge advice sheet – can print off from this guide, remember to check inhaler technique and consider a spacer

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]

 

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.
