Abstract To explore the influence of the different humidity in the incubator on the weight of premature infants. Methods: From March 2022 to September 2023, 100 premature infants (less than 37 gestational weeks) were selected and were divided into two groups (50 cases in each group) by random number table method. The neonates in the two groups were given care with different humidity in the incubator, including the neonates in the observation group with the humidity of 85%- 90% within 1 week after birth and the neonates in the control group with normal humidity of 55%-65%. The weight change of the neonates within 1 week after birth, the time of weight recovery and the complications rate of the neonates in the two groups were recorded. The score of neonatal skin condition rating scale (NSCS) of the neonates was compared between the two groups. Results: The weight loss of the neonates (32.8±10.3g) in the observation group on the 3rd day after birth was significantly less than that (43.1±13.8g) of the neonates in the control group. The weight gain (40.6±12.7g) in the observation group on the 7th day after birth was significantly more than that (30.5±9.0g) of the neonates in the control group. The scores of the skin dryness (1.45±0.31 points) and the skin damage (1.20±0.37 points), and the total score (3.83±1.02 points) evaluated by NSCS scale of the neonates in the observation group were significantly lower than those (1.70±0.25 points, 1.40±0.28 points and 4.43±0.95 points) of the neonates in the control group. The average daily weight gain (19.1±5.7g) of the neonates in the observation group during hospitalization was significantly higher than that (15.6±4.2g) of the neonates in the control group. The time to the weight return to the birth weight (6.00±1.45d) and the hospital stay (15.60±5.13 d) of the neonates in the observation group were significantly shorter that those (7.39±1.50 d and 18.67±5.97 d) of the neonates in the control group (all P<0.05). There were no significant differences in the incidences of pneumonia, upper respiratory tract infection, skin infection, diarrhea and thrush, and the total incidence of nosocomial infection of the neonates between the two groups (P>0.05). Conclusion: Appropriately increasing the ambient humidity of the premature infants in the infant incubator can slow their early weight loss, promote their weight gain, reduce their risk of skin damage, and without increasing the risk of infection, which is conducive to the growth and development of the premature infants.
