Parameters | Definitions |
Some/severe dehydration | Defined by “Dhaka methods” of assessment of dehydration, which is almost similar to WHO method and approved by WHO [32]. |
Severe wasting | <−3 Z score of weight for height of median value of the WHO [33]. |
Hypoxaemia | |
Hypoglycemia | Blood glucose <3 mmol/l measured by a bedside glucose test [13] |
Hypernatremia | |
Hyponatremia | |
Leucocytosis | Leucocyte count that exceeds the reference range for age [34] |
Neutrophilia | Neutrophil count that exceeds the reference range for age [34] |
Sepsis | Presence of inflammation [abnormal WBC count (>12 × 109/l or, <4 ×109/l or, band and neutrophil ratio ≥ 0.1) plus presence or presumed presence of infection with thermo-instability (hypo ≤ 35.0˚C) or hyperthermia (≥38.5˚C)], tachycardia (>2 SD above the normal value for age) in the absence of clinical dehydration or after correction of dehydration [22,35]. |
Severe sepsis | Sepsis plus signs of poor peripheral perfusions (absent peripheral pulses or capillary refilling time ≥ 2 s or hypotension) [22,35] |
Pneumonia | Defined by WHO guideline of acute respiratory tract infection [26] or presence of lobar or patchy consolidation |
Urinary tract infection | If the culture shows >100,000 colonies of a single pathogen, the child is considered to have UTI [34] |
