Premature babies need to sleep in the incubator. Premature babies have less subcutaneous fat and poorer ability to regulate their own body temperature, so they need a constant temperature and humidity environment to help them pass the danger period. Premature babies sleeping in the incubator can generally eat normally, breathe on their own, and weigh more than 2000g to be judged as out of the danger period and can be taken out of the incubator; and most preterm babies are combined with infection and other high-risk factors, so whether they can be taken out of the incubator needs to be combined with the existence of infection and other phenomena; in addition, whether the baby can be taken out of the incubator is not only related to body temperature, but also has a certain relationship with the room temperature, so it needs to be judged by the doctor In addition, whether the baby can be discharged from the incubator is not only related to the body temperature, but also to the room temperature.
