A 6-year-old girl is brought to the emergency department by her parents due to generalized tonic-clonic seizures that have been ongoing for 15 minutes. She recently returned from a 4-week trip visiting relatives in rural Uganda. Her parents report she has had a high fever, vomiting, and increasing lethargy over the last 3 days. She has not received any travel-related prophylaxis. On presentation, her temperature is 39.8∘C39.8^\circ\text{C} (103.6∘F103.6^\circ\text{F}), heart rate is 160/min160/\text{min}, and blood pressure is 85/50 mmHg85/50\text{ mmHg}. She is unresponsive to verbal stimuli. Point-of-care blood glucose is 45 mg/dL45\text{ mg/dL}. Arrange the following acute management steps in the most appropriate sequential order.

  1. 1Administer intravenous lorazepam and a bolus of 10%10\% dextrose
  2. 2Obtain thick and thin peripheral blood smears for parasite identification
  3. 3Initiate intravenous artesunate therapy
  4. 4Transition to a full course of oral artemether-lumefantrine

Cevap

The correct sequence is: 1) Administer intravenous lorazepam and a bolus of 10% dextrose, 2) Obtain thick and thin peripheral blood smears, 3) Initiate intravenous artesunate therapy, and 4) Transition to a full course of oral artemether-lumefantrine.
The patient presents with severe (cerebral) malaria complicated by status epilepticus and profound hypoglycemia. The absolute first priority in any critically ill patient is stabilization; thus, administering lorazepam to abort the seizure and dextrose to correct the hypoglycemia must occur first. Once stabilized, blood for thick and thin smears should be drawn to confirm the diagnosis and establish the baseline parasitemia before medications alter the results. Immediately following the blood draw, intravenous artesunate (the drug of choice for severe malaria) is administered. Finally, after the patient's neurological status improves and oral intake is tolerated, the patient must be transitioned to a full oral course of an artemisinin-based combination therapy to prevent recrudescence.

Adım Adım Çözüm

1
Stabilize life-threatening emergencies (status epilepticus and hypoglycemia) with lorazepam and dextrose.
Cessation of seizure activity and restoration of normal blood glucose levels.
Airway, breathing, and circulation (ABCs) along with correction of critical metabolic derangements always take precedence over diagnostic testing.
2
Draw blood for thick and thin peripheral smears.
Confirmation of Plasmodium falciparum infection and calculation of the baseline parasitemia percentage.
Diagnostic sampling must be performed before the administration of antiparasitic agents to avoid clearing the organism before species identification can be completed.
3
Administer intravenous artesunate.
Rapid reduction of the Plasmodium parasite burden in the bloodstream.
Intravenous artesunate is the standard of care for severe malaria (including cerebral malaria) and significantly reduces mortality compared to older regimens.
4
Prescribe a complete course of oral artemether-lumefantrine.
Complete eradication of the parasite and prevention of disease recrudescence.
Step-down to an oral artemisinin-based combination therapy (ACT) is strictly required once the patient regains consciousness and can safely swallow.

The sequential management of severe pediatric malaria involves immediate hemodynamic and neurologic stabilization, followed by diagnostic smears prior to the initiation of IV artesunate, and concluding with a transition to an oral artemisinin-based combination therapy.
