The Effect of the Use of Gel Pillows on the Sleep Quality and General Comfort Levels
Condition: Preoperative; Sleep; Comfort
Study type: Interventional

Summary: 
      The study was conducted to evaluate the effect of using gel pillows on the sleep quality and
      general comfort levels of patients in the preoperative period.The main hypotheses are:

      H1: 'The sleep quality of patients who use gel pillows in the preoperative period is higher
      than those who do not use gel pillows' H2: "The general comfort level of the patients who
      used gel pillows in the preoperative period is higher than those who did not use gel
      pillows".

      Participants will be asked to use a gel pillow with a cooling surface the night before the
      day of surgery.

      If there is a comparison group: Researchers will compare patients' control group to see if
      there is any difference in sleep quality and comfort levels.
    

Detailed description: 
      Randomization method will be used to determine the groups. Randomization of the patients was
      done using the 'Random Allocation Software 2.0' program and they are allocated into 2 groups:
      1) the control group and 2) the intervenion group.

        1. The Control Group: The patients in this group will be visited by the researcher in their
           rooms on the morning before the surgery. Patients will be informed that they will be
           visited again in the evening of the day before the surgery and that they will be given a
           pillow to use while sleeping at night. They will receive no other interventions.Patients
           will be visited again on the morning of the surgery day.The Richard Campbell Sleep Scale
           was used to evaluate the nighttime sleep quality of the patients;General Comfort Scale
           to evaluate comfort levels.

        2. The Intervenion Group: The patients in this group will be visited by the researcher in
           their rooms on the morning before the surgery. Patients will be informed that they will
           be visited again in the evening of the day before the surgery and that they will be
           given a pillow to use while sleeping at night. Patients who are visited in their rooms
           on the evening of the day before the surgery will be given a gel pillow with a cooling
           surface feature for night use. If patients stop using pillows at night, they will be
           asked to inform the investigator when they come to their room in the morning.Patients
           will be visited again on the morning of the surgery day.The Richard Campbell Sleep Scale
           was used to evaluate the nighttime sleep quality of the patients;General Comfort Scale
           to evaluate comfort levels.
    

Intervention name(s): Using a gel pillow
Intervention type(s): Other
Intervention description(s): Within the scope of the study, gel pillows with a cold surface were used in the patients in the study group. It is produced by combining the obtained special liquid with elastic material with NASA approved molecule exchange technology and is made of OEKO-TEX CLASS 1 certified material.Thanks to the gel material on the pillow surface, the surface temperature is reduced from 37°C to 24°C in about 10 seconds. It gives a feeling of coolness with its thermal conductivity feature.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: The research will be conducted using randomized controlled, experimental type and single-blind research methods. For this purpose, after the data are collected, they will be coded as A and B groups, so the researcher who will make the research statistics will analyze the data without knowing the study and control groups. Randomization method will be used to determine the groups. For this, the patients who meet the study criteria and volunteer will be assigned to the groups using the randomization program 'Random Allocation Software 2.0' according to the order of hospitalization.
Masking: Single (Outcomes Assessor)
