A Hypertensive emergency is any elevation in blood pressure in the presence of end-organ dysfunction. Aggressively treating severe asymptomatic hypertension (very high blood pressure without clear end organ damage) is not indicated, not supported by the literature and DANGEROUS. First, do no harm.
2020 International Society of Hypertension Global Hypertension Practice Guidelines
In accordance with most major guidelines it is recommended that hypertension be diagnosed when a person’s systolic blood pressure (SBP) in the office or clinic is ≥140 mm Hg and/or their diastolic blood pressure (DBP) is ≥90 mm Hg following repeated examination.

10. All Shock Explained
|Non-ischemic (high-flow)||Ischemic (low-flow)|
|Physical Exam||Typically painless, not fully tumescent||Painful, fully tumescent with corpus cavernosa rigidity without involvement of corpus spongiosum and glans penis|
|Aetiology||High-flow priapism is extremely rare and most commonly associated with antecedent trauma including blunt trauma, or resulting from needle injury of the cavernosal artery.||Low-flow priapism is caused by impaired relaxation and/or paralysis of cavernosal smooth muscle and in sickle-cell disease|

6. Did you know about the RULE OF TENS for Fluid Resuscitation in Burns?
Burns Rule of TENS:
1. Estimate burn size (TBSA) to the nearest 10%.
2. Multiply %TBSA x 10 = Initial fluid rate in mL/hr (for adult patients weighing 40 kg to 80 kg).
3. For every 10 kg above 80 kg add 100 mL/hr to the rate.

4. LFTs explained
- LFTs = ‘hepatocellular’ or ‘cholestatic’ arrangement based on the pattern of elevation.
- Hepatocellular pattern = transaminases > ALK
- ALT is generally considered to be more specific to liver damage
- Magnitude of aminotransferase elevation => guide initial diagnosis: mild (<5x), moderate (5-10x), or marked elevation (>10x)
- Mild = NAFLD, Drug Induced Liver Injury, Alcohol-Induced Liver Injury
- Moderate = Alcoholic Hepatitis, Biliary Tract Disease
- Severe = Acute Viral Hepatitis, Ischemic Injury, Acetaminophen Toxicity
3. The GCS is out-of-stock
Contrary to common belief, The Glasgow Coma Scale (GCS) is NEVER out-of-stock and the lowest score possible is 3.
- An intubated patient still gets 1 point for verbal meaning they score 3T…there is nothing like a 2T score (at least not in human beings)
- The phrase ‘GCS of 11’ is essentially meaningless, and it is important to break the figure down into its components, such as E3V3M5 = GCS 11.
- The Scale was described in 1974 by Graham Teasdale and Bryan Jennett (Assessment of coma and impaired consciousness. A practical scale. Lancet 1974; 2:81-4.) and is the most reference paper in medical literature
2. Nairobi Accident Hotspots
The most dangerous time to walk on Nairobi’s streets is on a Friday, around 7am, particularly along Mombasa Road.
1. Salter-Harris Fracture (remember the mnemonic SALTR)
- Slipped (i.e., through growth plate and not involving bone) / Type I
- Above growth plate (i.e., through metaphysis) / Type II (most common)
- Lower growth plate (i.e., through epiphysis) / Type III
- Through (i.e., through metaphysis growth plate and epiphysis) / Type IV
- Rammed (i.e., Crush injury) / Type V (worst prognosis)
#WDR2016 World Day of Remembrance for Road Traffic Victims
The World Day of Remembrance for Road Traffic Victims (WDR) is commemorated on the third Sunday of November each year – to remember the many millions killed and injured on the world’s roads, together with their families, friends and many others who are also affected. It is also a Day on which we thank the emergency services and reflect on the tremendous burden and cost of this daily continuing disaster to families, communities and countries, and on ways to halt it.
Shut up during triage or end up on antihypertensives (learnt this from one of our nurses today)
