Study summary

The permanent bedding of critically ill neonates and infants in the pediatric intensive care unit (PICU) for an extended amount of time can result in the development of pressure injuries (PI). PIs can form due to high and permanent local interface pressure induced by contact with bed surfaces or other medical devices. The currently used state-of-the-art support systems consist of conventional foam mattresses. In this study, the investigators explore the effect of a newly developed air mattress with regard to contact are and reduction in the average interface pressure in infants assigned to the pediatric intensive care unit of the childrens hospital in Zurich.

Read the detailed description

The permanent bedding of critically ill neonates and infants in the pediatric intensive care unit (PICU) for an extended amount of time can result in the development of pressure injuries (PI). This results in a further prolongation of the hospital stay, additional suffering of the patient, scarring, increased mortality and morbidity, and increased healthcare costs. Infants are at particular risk since their skin hasn't matured yet and is mechanically weak, and for example neonates lack a robust stratum corneum entirely. Furthermore, the thickness of their skin is reduced by 60% when compared to skin of adults. Thus, pressure cannot be equally absorbed leading to higher tissue internal stress. PIs can form due to high and permanent local interface pressure induced by contact with bed surfaces or other medical devices. Contact pressure can hamper blood flow in subcutaneous areas, increasing susceptibility for pressure injuries. While sophisticated equipment to manage the interface pressure and reduce the risk of developing pressure injuries is abundant for adults, very little is designed explicitly for neonates and infants. The currently available air mattresses are not being used due to safety concerns and impracticability. Furthermore, they are designed for infants from half a year of age and, thus, not considering the low body weight of premature babies or neonates. This is why the currently used conventional foam mattresses remain first choice. However, foam mattresses are designed for optimal support of a specific weight and, therefore, making them unsuitable for the use as a one-fits-all solution in a highly heterogenic patient cohort. In addition, compressed foam gets stiffer at compressed areas, increasing the local pressure impact and, thus, PI risk. On the other hand, the structures of the hereby-developed air mattress can freely move and optimally adjust to the patient's body shape. This increases contact area, reduces the average interface pressure and blunts local pressure peaks at the areas with the most indentation, ensuring a more homogenous pressure distribution at a lower level. This ultimately is expected to result in a lower PI incidence. As a side effect, lying comfort for the patient will be increased.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
