Background
Each year 4 million children die in the first 4 weeks of life
Global average of 30-36/1000 Live Birth Geneva WHO report,2005
Many neonatal deaths are preventable with existing low-cost intervention
Planners and policy makers required reliable cause-of –death information
Int J Epidemiol 2003;362-65-70
The reduction of child mortality has been included among the Millennium Development Goals(MDG-4) that the United Nations has set to be attained by year 2015.
With out reduction in global NMR MDG-4 will not be achieved
Strategies, which address inequalities both within a country and between countries, are necessary if there is going to be further improvement in global perinatal health.

NMRs ranged from 2 to 18 per 1000 live births. Based on 193 countries; the major causes Infection (sepsis/pneumonia, tetanus, and
diarrhea 35% Preterm birth 28% Asphyxia 23% 98% information on cause of death is lacking
because of inadequate vital registration (VR)

The major death determinants were low birth weight (LBW)/ prematurity, congenital malformation and birth asphyxia.
Respiratory insufficiency (89.9% of cases) and sepsis (36% of cases) were the main causes of neonatal deaths in low birth weight infants.

The overall neonatal mortality rate declined from 15.6 to 8.1/1000 live births (LB), and after excluding lethal malformations mortality fell from 14.0 to 5.6/1000 LB
Congenital malformations, RDS, and asphyxia were the 3 most common causes of death.
These conditions and severe immaturity account for 74% of deaths.

OBJECTIVE: To describe and monitor the causes of neonatal and postneonatal deaths in the Neonatal Intensive Care Unit (NICU) over a 10-year-period. METHODS: This is a descriptive study of all infants who died in the NICU from January 1995 until December 2004 at Riyadh Military Hospital, Riyadh, Kingdom of Saudi Arabia. Data were collected prospectively on all infants admitted to NICU. The cause of death for each infant was discussed and determined by at least 2 consultant neonatologists. Deaths were classified according to the modified Wigglesworth's classification of perinatal death. RESULTS: During the study period, there were 79871 live births and 526 deaths, in which 446 84.2% were inborn deaths and 80 15.8% were outborn. Of the inborn deaths, 251 infants died between 1-6 days, 103 died between 7-27 days, and 92 died after 27 days. Lethal malformations led to death in 36%, prematurity and its complications in 42%, hypoxic ischemic encephalopathy in 5%, while other specific diagnoses, combined, led to death in 17% of the cases. CONCLUSION: Prematurity and its complications followed by congenital malformations were the leading causes of death.

Objective
To describe trend in neonatal mortality in AFH Southern region between
1st January 2001 to 31st Dec 2006 Determine the major causes of death in different
birth weight group The data could be used to plan the future direction
of perinatal neonatal care at Armed Force hospitals south regions
Compare the outcome with Armed force hospitals programme.
04/19/23 29
METHODS
Descriptive analysis of data of all neonates died IN neonatal intensive care unit at AFHSR from January 2001 to Dec 2006
All perinatal and neonatal data collected from the maternal and neonatal medical records * The “underlying cause of death” is derived from
the diagnosis listed on each death certificate according to International Classification of
Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), ( 4th edition, Craig D. Puckett: volume 1,2,3 channel publishing Ltd
* Lotus approach 97 data program
04/19/23 30
METHODS In cases where the cause of death was in
doubt, case notes were reviewed with the doctor who certified the death of the neonate to arrive at a consensus direct cause of death
Exclusion criteria (D.R. DEATHS + STILL BIRTH)
The birth weight of 6-year study period was grouped into 3 groups
1) ELBW infants below 1000gm
2) VLBW infants 1000 -1499gm
3) Near term infant more than or equal to 1500gm
