About

Purpose: This study was conducted to examine the effect of warmed intravenous fluids (WIVF) on the core body temperature and the patients' thermal comforts during the postoperative period in patients undergoing transurethral resection of the prostate (TURP).

Design: This was a prospective, randomized controlled experimental study. Methods: A total of 105 male patients undergoing TURP surgery and bladder irrigation were randomized to one of either room temperature (n=51) or warmed intravenous fluids (n=54) groups in postanesthesia care unit. The fluids in the experimental group were warmed until the body temperature was reached 36.0°C.

Purpose: This study was conducted to examine the effect of warmed intravenous fluids (WIVF) on the core body temperature and the patients' thermal comforts during the postoperative period in patients undergoing transurethral resection of the prostate (TURP).

Design: This was a prospective, randomized controlled experimental study. Methods: A total of 105 male patients undergoing TURP surgery and bladder irrigation were randomized to one of either room temperature (n=51) or warmed intravenous fluids (n=54) groups in postanesthesia care unit. The fluids in the experimental group were warmed until the body temperature was reached 36.0°C. The intravenous (IV) fluid given to the two groups was 1000 ml of 0.9% isotonic sodium chloride solution.

Enrollment: 105 patients

Sex: Male

Ages: 37 to 90 years old

Volunteers: No Healthy Volunteers

• patients were undergoing bladder irrigation were included in the study.
• patients the sense, expression of heat by the patient in recovery,
• patient who accepted to participate to the study

Exclusion criteria

• patients have any infection, fever
• patients have underlying diseases (hypothyroidism, hyperthyroidism, diabetes, cardiovascular disease or kidney failure)
• patients who had mental deficiency that could prevent communication,

105 participants in 2 patient groups

Warmed Fluids

Experimental group

Description:

When patients recovered from the effect of anesthesia, awakened and were able to switch to normal spontaneous breathing, they were taken from the sober unit to the service or intensive care unit, and subsequent follow-ups were carried out by the researcher in these units. The IV fluid given to the patients in the intervention group was heated to 36ºC using the medical heating device.

Treatment:

Other: Warmed Fluids

Room Temperature Fluids

No Intervention group

Description:

When patients recovered from the effect of anesthesia, awakened and were able to switch to normal spontaneous breathing, they were taken from the sober unit to the service or intensive care unit, and subsequent follow-ups were carried out by the researcher in these units. The IV fluid given to the patients in the control group was given at room temperature without heating and without intervention
