Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, researchers developed a mattress made of 3D spacer fabric to relieve pressure during cardiovascular surgery. Following the development process, an initial assessment of the mattress's effectiveness was carried out on healthy volunteers. The same people lay first on the developed product and then on the surgical mattress in the supine position. In both cases, the pressure between the person and the mattress was measured using a force-sensitive resistor (using Interlink's FRS-406 series sensors). Thirty patients were included in the initial evaluation. A randomised controlled trial was then carried out with patients undergoing surgery (patients were divided into two groups; (a) mattress developed by the researchers and (b) standard operating theatre mattress). Sixty patients were divided into two groups using block randomisation. In the block randomisation, patients below or above body mass index 27 were equally distributed between the groups. Pressure levels were measured continuously during surgery using the same sensors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, the researchers developed a mattress made of 3D spacer fabric for pressure relief during cardiovascular surgery. Following the development process, an initial assessment of the mattress's effectiveness was carried out on healthy volunteers. The same people lay first on the developed product and then on the surgical mattress in the supine position. In both cases, the pressure between the person and the mattress was measured using a force-sensitive resistor (using Interlink's FRS-406 series sensors). 30 patients were included in the initial evaluation. A randomised controlled trial was then carried out with patients who underwent surgery (patients were divided into two groups; (a) mattress developed by the researchers and (b) operating theatre mattress in common use). 60 patients were divided into two groups using block randomisation. In the block randomisation, patients below or above body mass index 27 were evenly distributed between the groups. Pressure levels were continuously measured during surgery using the same sensors. Data were analysed using IBM SPSS software v26.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

There were two groups in the trial. The first group was the group in which the patients used the mattress developed by the researcher. This was the intervention group. In the second group, the patients used the standard operating theatre mattress. This was the control group

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

3D Spacer Mattress

For the patients in this group, the mattress which developed by the researchers was used. Pressure level between the body and the mattress was measured throughout the surgery.

Group Type EXPERIMENTAL

3D spacer Fabric Based Mattress

Intervention Type COMBINATION_PRODUCT

For the patients in the intervention group, the 3D spacer fabric-based mattress was used instead of the operating room theater mattress. The pressure level of the patients was monitored throughout the surgery.

Operating Room Mattress

For the patients in this group, the mattress which was in common use was used. The mattress used for the patients in this group was made up of foam. The pressure level between the body and the mattress was measured throughout the surgery.

Group Type NO_INTERVENTION
