CHILD NEUROLOGY, CRITICAL CARE AND INFECTIOUS DISEASES: THE INTERSECTION
A multidisciplinary Approach to CNS Infection
July 10, 2014
To present a case of CNS infection and discuss the multidisciplinary approach in the management of CNS infection and its complications.
Objective
1. To recognize, diagnose and manage status epilepticus which is a usual co-morbidity of CNS infection.
2. To discuss CNS infections and its differential diagnoses.
3. To emphasize the different diagnostic modalities necessary in the approach of CNS infections.
4. To provide the current management of CNS infections and its complications.
5. To design a framework for the long term care of post-infectious cases with CNS complications by a multidisciplinary team.
Specific objectives:
ID: JBU,4/M from Bulacan admitted for the first time
CC: depressed sensorium HPI:
◦ 2-week history of fever (T max: 39.6 C) relieved with Paracetamol
◦ No other associated S/S◦ Fever persisted until 3 days PTA, there was
decreased appetite and increased sleeping time◦ Admitted in a local hospital. Imp: Kawasaki disease◦ Patient then developed GTC seizures. Diazepam was
given at 0.3mg/kg/dose.◦ Transfer to PCMC
Case Protocol

in Nursery class prior to illness Birth/Maternal History: non-contributory Developmental History: at par for age Feeding: eats regular table food 3x/day Immunization: completed EPI
During transfer, patient continued to have brief generalized tonic-clonic seizures without regaining consciousness. Travel time was approximately 30 minutes.

Case Protocol
Objectives1. To recognize, diagnose and manage status
epilepticus.
How would you manage the patient? Neurology (7-10 min)
◦ Define status epilepticus (convulsive/non-convulsive)◦ Discuss the algorithm for the management of SE
(based on the PCMC CNS algorithm)1st line: benzodiazepines2nd line: long-acting AEDs (Pb, Phy, VA, LEV)
3rd line: Refractory SE (ICU) (MDZ drip, Pentobarbital, Thiopental, Propofol)
◦ Define subclinical status and the role of EEG
ICU (2 min)◦ ICU admission◦ ABCs in the mgt of SE

After diazepam, patient continued to have seizures lasting for more than 5 minutes. He was loaded with Phenobarbital with a loading dose of 20 mg/kg/dose, then maintained at 5 mg/kg/day.
Patient’s sensorium continued to deteriorate. Patient still has no eye opening with extension of the right extremities on pain stimulation. Pupils were 2 mm SRTL, with no corneals and no Doll’s. He was intubated using a 4.5 tube at level 15 and was hooked to the mechanical ventilator.

Summary
After a month, MRI was repeated which showed resolution of the abscesses. Ventriculomegaly persisted.
