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

Diuretic

Vasodilator

Inotropes

Hypomagnesaemia

Classification

  • Normal: 1.1-0.7
  • Mild: 0.69-0.5 – No symptoms or non-specific symptoms, such as lethargy, muscle cramps, or muscle weakness
  • Severe: <0.5 – Severe neurologic symptoms such as nystagmus, tetany, seizures, and cardiac arrhythmias

Signs/Symps (normally <0.5)

  • MSK: Muscle Twitch, Tremor, Tetany, Cramps
  • CNS: Apathy, Depression, Hallucination, Agitation, Confusion, Seizure
  • CVS: Tachycardia, Hypertension, Arrhythmia, Digoxin Toxicity
  • BioChem: Hypokalaemia, Hypocalcaemia, Hypophosphataemia, Hyponatraemia

Mental Capacity Act (2005)

Applies to all over 16’s

Principles

  1. Everyone is presumed to have capacity – until a lack of capacity has been established
  2. All practical efforts have been made to help patient make a decision
    • Explain decision and options as clearly and concisely as possible (be flexible)
    • Make every effort to help the person understand (language line, writing, etc.)
    • Are there others who might help them understand? (nursing, medical, family, freinds)
  3. People are free to make an unwise decision
  4. Anything done under the act MUST be in the patients best interest
  5. Carefully consider what is the least restrictive option

Ingested Magnets

Ingestion of Strong Magnets is a TIME CRITICAL EMERGENCY

(Multiple Magnets OR a single Magnet and Metallic Objects)

Strong magnets  (such as Neodymium)

  • Now common place around the house
  • From; fridge magnets to toys and peicings

Ingested:

  • Intestinal injury can occur within 8-24 hours
  • However, symptoms may take weeks to develop
  • Symptomatic patients are a SURGICAL emergency

Detection:

  • 2 views – to determine number of magnets (if in doubt assume multiple)

RCEM recommendation (best practice)

Swallowed Foreign Body – Metal Detector

Pseudo-Hyperkalaemia Pathway

When patients sent in by GP “” – how much do you do?

Pseudo-Hyperkalaemia Pathway

* Examples of High Risk Patients: Dialysis, Renal Transplant, CKD under renal team. Previous Hyperkalaemia.

** All patients being discharged need to be discussed or seen by a Tier 3+ level Dr who will assign themselves to the patient. Put the Diagnoses as ‘No abnormality Detected’ AND ‘Potassium Level.’

Streaming Pathway

Patients POC results, ECG and PMH reviewed.

Make sure the patients contact number is correct. Inform them if their lab result comes back high then we will contact them. OPer them the choice if the result is normal – would they like a phone call or not. Add their choice to the bubble I.e ‘no call’ ‘wants call’

Move the patient to the ‘Streaming’ Tab and record the time they left in the bubble. Once the lab result is back, if it is raised then recall the patient for treatment. If it is normal then discharge from the system ensuring to put the discharge time as when they left the department.

If the lab sample haemolyses – The decision to recall is at the discretion of the Tier 3+ doctor.

Notes

This pathway has been created as a guide to help reduce the investigation burden and length of stay of patients with pseudo-hyperkalaemia. The purpose of having an Tier 3+ level doctor responsible for these patients is they can make a quick global assessment of the patient and decide whether the patient is high risk and if the streaming pathway is appropriate, rather than relying on a regimented list of conditions or parameters.

In hours this should be done by the front door doctor. Out of hours Tier 1/2 doctors can still see these patients but they should then be discussed with a Tier 3+ Doctor.

2WW – Suspected Cancer

Some patients present to ED with symptoms or investigations suspicious an undiagnosed cancer, but don’t require emergency admission. To reduce the barriers to care the trust has implemented a referral route for ED.

Emergency Department MDT referral request – HERE

Once completed the PPC team will review the request and feed them into either “Fast-Track Clinics” if further workup required or MDT’s if fits those pathways.

This should allow our patients quick access to appropriate clinics, without the inherent delays and wasted clinical time of asking the patient to attend their GP. BMA/NHSe
