Introduction

Before OSCE:

o Sleep well: Sleeping well is more beneficial than studying all night long. o Bring all your equipment: Stethoscope, hammer, ophthalmoscope…" o The key to OSCE success is practice. o Behave in a polite, professional way.

Before starting any examination:

o Wash your hands. o Introduce yourself to the parents and the child. o Explain to the patient, take permission and maintain privacy. o Respect the child presence and establish a relationship. o Consider starting with auscultation if the child is quite. o After you finish, thank the child and cover him\her.

Spacer MDI inhalation technique

o Explain why it's used and what their effects and side effects are. o Explain that there is no risk of addiction. o Explain the technique: Demonstrate and let the patient to do it.

Check the expiratory date. Remove the cap of the inhaler & spacer then shake (3-4 times). Attach the inhaler to the spacer. Put the mouthpiece into the child's mouth. Spray 1 puff into the spacer by pressing down on the canister. Keep the spacer attached tightly to the child's nose and mouth

for 5-10 seconds. Explain that there is no risk of suffocation. In case of more than on puff, repeat the steps after one minute. Wipe mouthpiece and cover it &Wash it twice a week. Wash the spacer with water weakly and let it dry by itself.

o If the patient uses 2 types, use the dilator first. o If the patient uses steroid, wash the mouth after (candidiasis).

Approach to Gastroenteritis

Airway Breathing Circulation.

Assessment of dehydration:

o Mild: Everything is normal except for dry mucous membrane. o Moderate: You see most of the signs of dehydration listed on the table

below. o Severe: Moderate + Anuria and lethargic due to decreased end-organ

perfusion.

Management of dehydration:

o Bolus if in shock (tachycardia and hypertension): IV NS 20 ml/kg. o Deficit: over 24 hour (the first half on the first 8 hours).

Infants (5%: 50ml/kg, 10%: 100ml/kg, 15%:150ml/kg). >1 year (3%: 30ml/kg, 6%: 60ml/kg, 9%:90ml/kg).

o Maintenance: should be added to deficit. 100 ml/kg/day or 4 ml/kg/hour for the 1st 10 kg. 50 ml/kg/day or 2 ml/kg/hour for the 2nd 10 kg. 20 ml/kg/day or 1 ml/kg/hour for every kg.

o E.g. 4 kg with moderate dehydration: Maintenance=16 ml/hr. Deficit=400 ml/day (200ml/8hr= 25 and 200ml/16hr= 12.5). The first 8 hr= 16+25= 41ml/hr. The next 16 hr=16+12.5=28.5ml/hr.

o Use for maintenance: Dextrose 5% 1/2 Normal Saline. If high Na, NS. o Indications for admission: Severe, systemic infection (Sheigella, E-coli),

not responding to ORS.

Page 8: Pediatrics OSCE

P a g e | 7 Pediatric Block OSCE | AlBrahim & Tarabzoni

Oral rehydration solution (ORS)

o ORS is the best to replace ongoing loss except for persistent vomiting, intolerance to oral feeding, or severe dehydration.

o ORS: small, frequent, 2-3 minutes after vomiting. o 2 types of ORS (Pedialyte – high in sugar-, WHO –high in salt-).

Investigations:

o CBS and differentials. o Electrolytes (K, Na). o BUN and Creatinine. o Glucose (DKA is a differential diagnosis of GE). o Urine analysis and culture. o Blood culture.

Miscellaneous presentations:

- The most common cause of gastroenteritis (GE) is Rotavirus. - If GE + seizure sheigella. - If GE + hemolytic uremic syndrome (low Hgb, low Plt) E-coli. - If GE + decreased immunity cryptosporidium. - If GE then persistant diarrhea: Secondary lactose intolerance. Resolve in 3 weeks. - If GE then paralysis after 3 weeks Guillain Barre syndrome.

Type 1 Diabetes

Etiology: o T-cell mediated autoimmune destruction of islet cell cytoplasm, insulin

autoantibody.

Pathophysiology: o Diabetes:

Hyperglycemia osmotic dieresis; when renal threshold for glucose reabsorption is reached (180 mg/dl) glycosuria.

Loss of fluid, electrolyte, calories, and dehydration.

o DKA: Accelerated lipolysis and impaired lipid synthesis

lincreased free fatty acids ketone bodies metabolic acidosis (aggrevated by lactic acidosis due to dehydration) and Kussmaul respiration (to wash out CO2) decreased consciousness.

K level could be high in the blood due to acidosis but depleted intracellular K.

Clinical presentation: o Polyuria, polydipsia, polyphagia, weight loss o 20-40 % initially present with diabetic ketoacidosis which should be

suspected in any patient presented with: Dehydration. Acidotic (Kussmaul’s) breathing, with a fruity smell

(acetone). Abdominal pain and\or distension. Vomiting. Altered mental status ranging from disorientation to coma.

Precipitating factors to DKA: o New onset of type 1 DM. o Infections (the most common cause in general). o Drugs: e.g. Steroids, thiazides. o Omission of Insulin: The most common in adolescent. This is due to:

Non-availability. Fear of hypoglycemia. Rebellion of authority. Fear of weight gain (Diabulimia). Stress of chronic disease.

Page 26: Pediatrics OSCE

Diagnosis of diabetes: o Symptoms + Random glucose > 200 mg/dl or 11.1 mmol/l. o Fasting blood sugar > 126 mg/dl or 7 mmol/l. o 2 hour OGTT 200 mg/dl or 11.1 mmol/l.

Diagnosis of DKA: o Hyperglycemia: of > 300 mg/dl & glucosuria (could be normal due to

insulin given at home). o Ketonemia and ketonuria. o High anion gap metabolic acidosis: pH < 7.3, serum bicarbonate < 15

mmol/l. Anion gap >10. o Anion gap= [Na]+[K] – [Cl]+[HCO3]. o (This is usually accompanied with severe dehydration and electrolyte

imbalance).

Management of DKA: o History: Symptoms of hyperglycemia, precipitating factors, diet and

insulin dose. o Examination:

Look for signs of dehydration, acidosis, and electrolytes imbalance, including shock, hypotension, acidotic breathing, CNS status…etc.

Look for signs of hidden infections (Fever strongly suggests infection) and If possible, obtain weight.

o Quick Diagnosis: In known diabetic children confirm: hyperglycemia,

ketonuria and acidosis. In newly diagnosed diabetic children: be careful not to miss

it because it may mimic serious infections like meningitis. Blood glucose level (using glucocheck) glucosuria, &

ketonuria (using dip stick) must be measured in the ER and treatment should be started without waiting for Lab results which may be delayed.

o Lab investigation: Plasma & urine levels of glucose & ketones. ABG, Electrolytes (including Na, K, Ca, Mg, Cl, PO4, HCO3). Complete Blood Count with differential. Further tests e.g., cultures, X-rays are done when needed.

o Fluid: If in Hypovolemic shock, 0.9% saline as a bolus (20 ml/kg). If Dehydration without shock

- Calculate the deficit as per the degree of dehydration (mild, moderate, and severe). - Administer 0.9% NS 10 ml/kg/hour for an initial hour, to restore blood volume and

renal perfusion. - The remaining deficit should be added to the maintenance, & replaced over 36-48 hr. - To avoid rapid shifts in serum osmolality (cerebral edema) 0.9% Saline can be used

for the initial 4-6 hours, followed by 0.45% saline. Keep the child NPO till pH is >7.3 and bicarbonate is >15. If the child is comatose, ABC.

o Electrolyte: Start after 1 hour. Potassium: Regardless of K conc. at presentation, total

body K is low. So, as soon as the urine output is restored, potassium supplementation must be added to IV fluid at a conc. of 20-40 mmol/l (4-6 mEq/kg/24 hr at a rate of maximum 0.5 mEq/kg/hr).

o Insulin: Start after 1 hour. Start infusing regular insulin at a rate of 0.1U/kg/hour using

a syringe pump. Optimally, serum glucose should decrease in a rate no faster than 100mg/dl/hour to prevent cerebral edema.

Continue the Insulin infusion until acidosis is cleared: pH > 7.3, bicarbonate > 15 mmol/l, normal anion gap 10-12.

If blood glucose <15, give dextrose 5-10%. Can decrease gradually to reach 0.02 U/kg/hour and leave

till you are ready to switch to SC insulin. IV insulin is discontinued ½ hour after SC insulin is given.

o Subcutaneous (SC) Insulin: 0.5 U/kg/day, divided into 2/3 n the morning and 1/3 in the evening (almost 2:1 ration of NPH to regular)

Complication of insulin: o Hypoglycemia (sweating, irritability, tremor, anxiety, palpitation,

confusion, seizure, coma). o Weight gain: It can be avoided with good diet and exercise. o Lipoatrophy and lipohypertrophy.

Teaching about diabetes: o Deal with the patient psychology (denial, anger, depression, adaptation). o Background information about physiology (glucose and insulin),

pathology in DM. o Insulin: types, effects, how to use (subcutaneous). o Blood glucose home monitoring, urine for ketones. o Hypoglycemia: if symptoms present, oral sugar containing fluid should be

taken. Glucagon 30 ug/kg/dose if unconscious or seizing. o Illness management: they can affect DM patients in 2 ways:

Lack of appetite which can lead to hypoglycemia. Hyperglycemia and ketosis.

Outpatient care: o Follow up every 3-4 months with HbA1C. o Check clinically and biochemically for the associated condition e.g.

hypothyroidism every 1-2 years, celiac disease, and vitiligo.

Complications of diabetes: o Retinopathy, neuropathy, nephropathy, and failure to thrive.

Adolescent and diabetes: o Increased risk for psychiatric comorbidities (suboptimal disease control). o Family support is the most important factor in preventing the onset

psychiatric problem in adolescent with T1DM. o Barriers to self-management of T1DM in adolescents:

Peer pressure and lack of awareness of the disease. Family struggle and rebellion against authority. Embarrassment about the diagnosis. Search for identity and frustration with life changes.

o Warning signs of eating disorder in T1DM adolescents: Hyperglycemia and poor glycemic control. Frequent DKA and early onset microvascular complication. Poor self-esteem, depressive symptoms and anxiety. Weight loss or excessive exercise. Preoccupation of meal planning and binging. Severe family stress. Delayed onset of puberty.
