Objective: Determine the effectiveness of the use of polyethylene bags for the prevention of hypothermia in premature and low birth weight newborns. Materials and Methods: Observational and retrospective systematic review, the search has been restricted to articles with full text, and the selected articles were subjected to a critical reading, together with the intensive bibliographic search algorithm and the PICO strategy. Results: 10 articles were obtained as a population, of which 100% (10/10) demonstrated that the use of the polyethylene bag to prevent hypothermia in premature and low birth weight newborns is effective; We also point out that of these, 20% correspond to the United States as well as those from Mexico, while 10% are from Uruguay, Canada, Thailand, Zambia, Brazil and England respectively. Therefore, it is concluded to consider the use of polyethylene bags as an additional effective and safe intervention to prevent hypothermia in premature and low birth weight newborns. Conclusions: 100% (10/10) of scientific articles have shown that the use of polyethylene bags is effective in interrupting heat loss through convection, conduction and evaporation mechanisms. Likewise, by preventing hypothermia we not only find stable oxygen saturation but also other vital functions and consequently the most serious complication such as neurological damage is avoided.
