Preterm babies are those born before 37 weeks of gestation. They often have low birth weight and exhibit signs of clinical immaturity. Common problems include respiratory (HMD, BPD), gastrointestinal (NEC), cardiovascular (PDA), neurological (IVH, ROP) and thermal instability issues. Management involves providing supportive care in the NICU, including warmth, minimal stimulation, feeding and monitoring for complications. Nursing care focuses on thorough assessment, monitoring for problems, providing developmental care and teaching parents for home management of preterm infants.
