Overview :

The Neonatal Morbidity Scale was developed by Minde et al to evaluate the relationship between the severity of complications in premature infants and subsequent maternal-child interactions. The score is based on 20 of the most common significant problems seen at the Hospital for Sick Children in Toronto, Canada.

 

Parameters:

(1) convulsions

(2) hydrocephalus

(3) intracranial hemorrhage

(4) perinatal asphyxia

(5) diarrhea

(6) necrotizing enterocolitis

(7) meningitis

(8) sepsis

(9) pneumothorax

(10) apnea

(11) respiratory distress syndrome

(12) chronic lung disease

(13) cardiac failure

(14) hyperbilirubinemia

(15) hypoglycemia

(16) acidosis

(17) bleeding tendency

(18) anemia

(19) NPO status

(20) tracheostomy
