Background: The Neonatal Intensive Care Unit is specially built to prevent pain, promote quiet sleep and maintain stable physiological parameters among preterm neonates. The essential components of brain development in neonatal period are sleep. Nesting is individually modelled and specially designed and has proved in providing effective comfort, support and help preterm to develop normally in NICU. Neonatal Nurse requires skill, dedication and emotional strength to care for newborn, preterm and sick infants.

Aims: Thesis of the study is to evaluate effectiveness of nesting on sleep pattern and physiological parameters of preterm infants and also to find the correlation, association between the sleep pattern with physiological parameters.

Method: A Qualitative research, pre-test and post-test control group design was adopted. A total Premature Neonates were selected using non- probability purposive sampling and assigned equally into study (n=30) and control (n=30) groups admitted in SNCU. The study group received nesting technique to assess the sleeping pattern and physiological parameters in premature neonates admitted in SNCU. Sleep pattern assessed by Modified Prechtl’s criteria and self-structured observation check list to assess physiological parameters (Heart rate, respiration rate and saturation of oxygen through biomedically tested standard equipment through Cardiac Monitor).

Results: The findings of the study revealed that there was a significant improvement in sleep pattern and Physiological Parameters after intervention of Nesting at ‘p’ value < 0.05 level of significance. Statistical analysis using paired and unpaired test confirmed the effectiveness of the intervention. Premature Neonatal outcomes were also favorable in the intervention group, with higher sleeping pattern with maintain physiological parameters. In the post-test assessment, a remarkable induction in sleep pattern and maintained physiological parameters in study group. Their mean sleep pattern increased (SD =1.92) compared to (SD=3.45) in the control group. Their mean in physiological parameters (heart rate, respiration rate, saturation of oxygen) stable heart rate to (SD=6.12 to SD 6.12) in control group, respiration rate (SD=5.22 to SD=3.15) in control group and saturation of oxygen (SD= 10.55 to SD=6.60) in control group. The statistical test confirmed a significant difference (t= 5.13, p =<0.001). Premature neonates their physiological parameters also reflected an improved by the Nesting technique intervention.

Conclusion: The mean Post test score of Sleep Pattern and PP (Physiological Parameters)

5.20 and 5.96 and 10.55 were significantly higher than the mean pretest score of 5.13 and 9.96, 4.86, 1.81. The findings clearly revealed that nesting was effective in increasing the Physiological Parameters and Sleep Pattern in the Preterm Neonates. And a significant correlation at p<0.05.
