Estimating blood loss
Ask the patient!
Soaked linen (towels, bedding, clothing)
On the floor (may be vomitus)
Consider the area covered by a pint of milk if
dropped
Blood in water goes a lot further!
Pure blood clots easily in air
Physiological disturbance

Tonsillitis – relevant history
pain on swallowing
fever (>38°C [>100.5°F])
tonsillar exudate
tonsillar erythema
tonsillar enlargement
presence of cough or runny nose (-ve)
enlarged anterior cervical lymph nodes

Tonsillitis
5% to 10% of adults - caused by group A
beta-haemolytic streptococci (GABHS)
If suspected treat with Antibiotics (PenV 10
days – see local guidelines)
Centor score is a well calibrated CPR score
for suggesting a high probability of a patient
>14 years old with acute tonsillitis having a
GABHS infection.

Tonsillitis
The Centor criteria are: History of fever over 38°C (100.5°F)
Tonsillar exudate
Absence of cough
Tender anterior cervical lymphadenopathy.

Tonsillitis
Centor score ≥3 = positive predictive value is
40% to 60% of a GABHS infection.
Score of ≤1 negative predictive value of 80%
. . . do you want to see that again?

Tonsillitis - Complications
Rheumatic fever
preventable with antibiotics. However, its low incidence
(<1:100,000) renders their routine use in low-risk
populations (i.e., in developed countries) unjustified
Glomerulonephritis
no evidence that antibiotic treatment can prevent it
The efficacy of antibiotics is lessened in terms of
symptom reduction after 3 days, and, beyond 9 days
of symptom onset, for rheumatic fever prevention

Tonsillitis - Treatment
Analgesia
Antibiotics – local guidelines (Pen V 500mg
tds PO 10/7)
Steroids (10mg Dexamethasone IM)
IV fluids or supportive measures

Tonsillitis - Antibiotics
Antibiotics are also indicated in patients who
are critically unwell or from vulnerable
populations in which susceptibility to acute
rheumatic fever is high (e.g., in South Africa,
Australian indigenous communities, Maori
communities of New Zealand, the
Philippines, and in many developing
countries).

ASSESMENT OF EPISTAXIS ABC
HISTORY SHOULD COVER THE FOLLOWING
Degree of bleeding in last 24 hours
If patient had similar problem before
Search for causative factors like (Trauma,Tumour and
Infection)
Nose picking habit
Hay fever history
Recent Air travel
Drug history
