Q

Initial Management of an epiglotitis patient.

A

Do not disturb the child
Ask mother to keep oxygen mask on child’s face.
Do not examine throat, do not cannulate
Call anaesthetist and ENT Surgeon
Send the child to theatre or ICU
Intubation in Theatre

Put a canula and start IV antibiotics (Cefotaxime, ceftriaxone)
When child gets better, Take tube out and send to ward.

Q

Mx of a child presenting with FB Aspiration

A

If FB clearly visible in mouth, take it out in direct vision (Blind finger sweeping is not advised).
If FB not visible but child can cough, encourage coughing.
If coughing does not bring FB out or child does not cough - Back blows, chest thrusts, abdominal thrusts.
If that does not work, cricothyroid puncture.
If that does not work, Tracheostomy
If that does not work, Bronchoscopy

Q

What are the X-Ray changes in a FB aspiration causing Complete obstruction?

Q

What are the X-Ray changes in a FB aspiration causing incomplete obstruction?

A

Affected lung will be hyperextended. Trachea deviates to the opposite side.

Hyperexpansion - Since inspiration is an active process and expiration is passive, while air comes in not all air comes out collecting air leading to hyperexpansion.

    If Yes - DC Shock
    If No - Adenosine, Amiodarone
78
Q

How is Adenosine administered?

A

It has a very short life. It should be administered as a rapid injection from a vein near to the heart followed by a normal saline flush.

79
Q

How do you calculate the normal Systolic BP?

A

80 + (Age * 2)

79
Q

13yrs old 40Kg child with severe diarrhea and vomiting for 5 days presented with drowsiness. PR - 160/min. BP - 70/40mmHg. CRT - 5s. What is the most likely Dx?

A

Hypovolemic Shock.

79
Q

How do you initially approach Hypovolemic shock?

A
  1. Put 2 cannulae and then give a crystalloid - Normal saline 20ml/kg RAPID BOLUS (Squeeze bottle)
  2. If no impovement - repeat Normal saline 20ml/kg rapid bolus.
  3. If no impovement - Give a colloid.
  4. If no impovement, Give a vasoconstrictor - Adrenaline
80
Q

What are the types of Colloids?

A

Dextran, Hetastarch, Blood

81
Q

In general practice, why isn’t a colloid given as the first step of Mx of Hypovolemic Shock?

A

Expensive
Remains in circulation for a long time
Can cause anaphylaxis by reacting

82
Q

A child developed difficulty in breathing and faintishness while on a blood transfusion. What’s the most likely Dx?

A

Anaphylaxis/ Anaphylactic shock

83
Q

What are the features of anaphylaxis?

A

Rhonchi on auscultation
Vasodilatation leading to reduced blood supply to brain causing faintishness

84
Q

Mx of anaphylaxis due to a blood transfusion

A

Stop blood transfusion immediately
IM adrenaline 0.01ml/kg 1 : 1000

DUMBBELSS
Diarrhea
Urination
Miosis
Bradycardia
Bronchoconstriction
Emesis
Lacrimation
Secretions
Salivation

128

Organophosphate blocks the activity of Acetylcholine esterase causing accumulation of Ach.
Accumulated Ach causes hyperstimulation of Muscarinic and nicotinic receptors. leading to a cholineregic crisis
