10. Que 5
A 54-year-old woman undergoes thyroidectomy for follicular carcinoma of the thyroid. About 6 h after surgery,
the patient complains of tingling around her mouth. She subsequently develops a pins-and-needles sensation in
the fingers and toes. The nurse calls the physician to the bedside to evaluate the patient after she has severe
hand cramps when her blood pressure is taken. Upon evaluation, the patient is still complaining of intermittent
cramping of her hands. She has had no change in her vital signs and is afebrile and ECG was as below. What is
the next step in evaluation and treatment of this patient?

Total T3 0.6 nmol/L (0.9–2.5 nmol/L)
1) Interpretation of thyroid profile
2)How will you treat this patient ?
15. Ans 7
1) Sick euthyroid
low total T3 level associated with normal T4 and thyroid-stimulating hormone
(TSH) levels. The absence of a high TSH level excludes primary hypothyroidism.
This pattern would fit a
2) No active management. Observation
Abnormalities in the levels of circulating TSH and thyroid hormone are thought
to result from the release of cytokines in response to severe stress

40-year-old woman posted for posterior spinal fusion. During the pre- anesthesia
evaluation she had tachycardia and hypertension which was optimised and posted for
surgery. Induction of anaesthesia was uneventful. Intr oprative she had rise in

20. Que 10 A 33-year-old man, without known co-morbidities, was brought into the emergency
department with sudden onset of headache and severe central chest pain, radiating to the back. Heart
rate 105 beats per minute, blood pressure was 180/125 mmHg, temperature 36.1°C, oxygen-
saturation 98% and the respiratory-rate was 28 per minute. An arterial blood gas (ABG) revealed
significant lactate acidosis with pH 7.14, pO2 of 15.4 kPa, pCO2 of 4.5 kPa, bicarbonate of 12 mEq/L,
base excess of −16 mmol/L and lactate value of 12 mmol/L.
Bedside echocardiography revealed regional
hypokinesia in the lateral area of the left
ventricle, and an estimated left ventricular
ejection fraction (LVEF) of 20–30%. The
patients’ blood samples demonstrated
abnormal with a troponin T of 300 ng/L,
white blood cell count of 39 × 109/L and
normal c-reactive protein. Non enhanced CT
is as shown.

dysfunction?
21. Ans 10
1) Right adrenal pheochromocytoma
2) Catecholamine-induced or takotsubo-like cardiomyopathy

Urine sodium was 49 meq/L. Urine osmolality was 145 mosmol/kg
1) Diagnosis
2) How you will manage ?
23. Ans 11
1) Cerebral salt wasting syndrome
2) Mild to moderate hyponatremia : isotonic saline . isotonic fluid provides the
fluid for the hypovolemic patient as well as helps to restore the body's sodium
stores.
Moderate to severe hyponatremia: more aggressive sodium replenishment may
be required with either hypertonic saline 3% hypertonic saline and/or salt tabs
(1 to 2 grams up to three times daily) and fludrocortisone
