Body Temperature Changes and Early Postoperatıve Pressure Sore

The Effect of Body Temperature Changes Durıng Total Knee Arthroplasty Surgery on The Formatıon of Early Postoperatıve Pressure Sore

This study aims to determine effect of body temperature changes during total knee arthroplasty surgery on early postoperative pressure sore formation.

BACKGROUND: Intraoperative hypothermia for a prolonged period increases the risk of hospital-acquired pressure sores.

PURPOSE: This study aims to determine effect of body temperature changes during total knee arthroplasty surgery on early postoperative pressure sore formation.

METHODS: This experimental study was performed with experimental-control group (N=122) patients. Data were collected with "Personal Information Form", "Body and Ambient Temperature Record Form", "Braden Risk Assessment Scale". Experimental group participants were covered with a wool blanket, and control group was given standard care.

Inclusion Criteria:

• Aged 20-85 years
• Hospitalized for at least four days and accepted to participate were included in the study.

Exclusion Criteria:

• Under the age of 20 - over 85,
• Pregnant and having comorbid diseases,
• Spinal cord injuries,
• Skin problems in areas where there is a risk of pressure loss,
• Undergoing hemodialysis,
• Having creatinine and serum albumin levels higher than 3 mg/dl,
• Having immobility, incontinence, anemic, having malignant tumor(s),
• BMI <19 or BMI >40,
• Hemoglobin level below 10 g/dl,
• Infection,
• American Society of Anesthesiology (ASA) score of 3 or more,
• Experiencing friction, tearing and shearing,
• Undergoing more than one surgical intervention,
• Having conditions requiring the use of non-normal anesthetic agents and sedation,
• Using vasoconstrictive drugs,
• Using positioning devices,
• Undergoing prolonged surgical intervention,
• Having arterial pressure lower than 32 mmHg,
• Having diabetes mellitus requiring insulin therapy.
