Respiratory Flashcards
Massive Hematemesis
Defined by volume of blood:
Typically: 100 – 600ml/24 hours for MASSIVE
Cardiac cause of massive heamatemesis
- PE / infract
- M. Stenosis
- AVM
- Ateriobrachial fistula
pneumothorax finding on chest x-ray
White visceral pleural line
No pulmonary vessels visible peripherally
absence of lung vessels lower lobes
gaol when treating pneumothorax
- remove air from pleural space
2. prevent recurrence
Contra-indications to chest drain insertion
Bleeding disorder
INR > 1.5
Platelets < 50 x 109, or dysfunctional (uraemia, anti-platelet agents)
Patient on anti-coagulation (DOAC’s / Warfarin)
Diagnosis is uncertain
Lung adherent to chest wall
Complication at insertion of chest drain
At insertion
Pain
Infection
Neurovascular bundle damage
Haemorrhage (Perforation of aorta / pulmonary vessel)
Subcutaneous emphysema
Lack of resolution / Failure of procedure
Re-expansion pulmonary oedema
Organ injury/perforation (liver / spleen)

S And S life threatening
SYMPTOMS Decreasing level of consciousness Difficulty completing sentences Severe dyspnoea No symptomatic relief following immediate trial of frequent inhaled beta-2-agonist
SIGNS Looks distressed Looks exhausted Cyanotic Silent Chest Bradycardia Hypotensive Confused Comatose
SS severe asthma
Symptoms:
Unable to complete sentences
Only partial relief to immediate trial of frequent inhaled beta-2-agonist
Previously symptoms last > 3 days after treatment initiated
Sign:
Resp rate > 25 bpm
HR > 110 bpm
BP = within normal limits
PEFR
< 33-60% of Predicted or Best
Moderate asthma
Symptoms: Increasing symptoms
No features of acute severe asthma
PEFR
> 50-70% predicted or best
If no responds to normal tx of acute asthma
If not responding consider:
ICU review: ventilator support
IV Magnesium
IV beta-agonist, aminophylline
Signs of severity in asthma
Other signs to examine for: Pluses Paradoxus Use of Accessory Muscles Diaphoresis Inability to lie supine, tachycardia
Risk factors for acute asthma
Previous severe exacerbation (e.g. ICU admission/mechanical ventilation required)
>2 hospitalizations for asthma in the last year
>3 A&E visits for asthma in the last year
Hospitalisation/A&E visit for asthma within the last month
Use of more than two canisters of short-acting beta agonist per month
Difficulty perceiving asthma symptoms/severity
Difficult social circumstances/lack of access to primary care
Co-morbidities: cardiovascular, chronic lung, or psychiatric disease
