Abstract
This prospective study was undertaken in Dhaka Shishu Hospital from 15th March 2005 to 15th October 2006 to determine the role of micro-ESR and immature and total neutrophil (I/T) ratio in early diagnosis of neonatal septicaemia. Eighty suspected cases of septicaemia admitted in neonatal ward of Dhaka Shishu Hospital were included in this study. Patients those who had history of perinatal asphyxia, infant of diabetic mother, congenital cyanotic heart disease etc. were excluded from the study. Thirty neonates without sign symptoms of septicaemia admitted for other causes like jaundice, feeding problems etc. were taken as a control group. After taking informed consent data were collected in structured questionnaire. Following hematological investigations like total WBC count, differential count, absolute neutrophil count, band cell count, platelet count, CRP, blood culture were done. Micro-ESR was done as bed side test. I/T ratio detected from total neutrophil and band form count. Patients with positive blood culture were categorized as definite sepsis. Patients with negative blood culture but abnormal hematological report suggestive of sepsis were categorized as probable sepsis. Those who had no signs of sepsis were categorized as control group. Micro-ESR more than age of the patient in days + 3mm in 1st hour were considered significant for sepsis. I/T ratio more than 0.2 was considered positive for sepsis. Sensitivity and specificity of micro-ESR was 63.3% and 60% respectively. Sensitivity and specificity of I/T ratio was 70% and 56% respectively. Combination of micro-ESR and I/T ratio showed high sensitivity (80%) and specificity (70%).
