(Universidad Privada Norbert Wiener, 2018-11-25) Callata Cisneros, Veronica Esther; Peralta Ccuno, Maribel Eulalia; Bonilla Asalde, César Antonio
Objective: To analyze the evidence on the effectiveness of adequate humidity in incubators to prevent heat loss in the premature newborn. Material and methods: Of the articles reviewed, 10% (N= 1/10) his design is systematic reviews, 20% (N= 2/10) are meta-analysis, 30% (N= 3/10) are descriptive, 10% (N= 1/10) is transversal analytical, 10% (N=1/10) is controlled and randomized clinical trials, 10% (N=1/10) is cases and controls and 10% (N=1/10) is prospective. According to the strength of recommendation strong 30%, weak 40% and very weak 30%, according to the country where the investigations were carried out, there were found: France 40%, Brazil 20%, USA 30% and Argentina 10% respectively. Results: According to the review, it is evident that 100% of the articles (N = 10/10) point out the effectiveness of adequate humidity in incubators to prevent excessive heat loss in the premature newborn. Conclusion: It is concluded that the systematic review of the 10 scientific articles points out the effectiveness of adequate humidity in incubators to prevent heat loss in the premature newborn, because it manages to maintain a balance between the partial vapor pressure of the water close to the skin and the surrounding air, thus avoiding high insensible losses due to evaporation and therefore preventing heat loss.

Effectiveness of heated humidifiers in reducing dryness of the mucosa in the airways related to non-invasive ventilation
(Universidad Privada Norbert Wiener, 2017-12-03) Villagomez Chang, Liz Maribel; Rivera Lozada de Bonilla, Oriana
Objective: To systematize the evidence on the efficacy of heated humidifiers in reducing mucosal dryness in the respiratory airways related to non-invasive ventilation. Materials and Methods: Systematic review, observational, and retrospective study. The search was restricted to 14 full-text articles, which were critically reviewed using the GRADE evaluation to determine their level of evidence. The studies were conducted in France, Italy, Japan, Spain, New Zealand, and Australia. In the final selection, 100% (14) were randomized controlled clinical trials, with 28.6% (4) from France and Japan, 21.4% (3) from Italy, and 7.1% (1) from Spain, New Zealand, and Australia. Results: 92.9% (13/14) affirmed the efficacy of heated humidifiers in reducing mucosal dryness in the respiratory airways related to non-invasive ventilation, while 7.1% (1/14) did not recommend using heated humidifiers for this purpose. Conclusions: The 13 studies reviewed show that heated humidifiers are effective in reducing mucosal dryness in the respiratory airways related to non-invasive ventilation, while 1 study does not recommend their use for this purpose.
