Clinical Trial Summary

The aim of study is to investigate the effects of active external warming of patient concurrently with application of ice to incision site on thoracotomy pain and analgesic consumption. The research is a quasi-experimental design with control and study groups.

Description:

The study was initiated after obtaining the written approval of the study centers. The center of the study and the hospital where the research was conducted. Written permission was obtained from the hospital management. Within the scope of the research, the research was explained to the participants and their consent was obtained.

The routine analgesia protocol was applied to patients in the control group. In addition to the routine analgesia protocol, the study group was administered non-pharmacological pain control interventions comprising active external warming and ice application. In the Intensive Care Unit (ICU), all patients stayed in the same area without a separator so they could easily observe each other's interventions and hear the conversations occurring during medical intervention. For this reason, the control group was evaluated first. After the last patient in the control group was transferred to the clinic, the study group was evaluated.

Active External Warming: In the literature, the use of electric blankets and warm blowing devices were recommended as the best methods for postoperative active external warming.In this study, methods used routinely in the Intensive Care Unit (ICU) such as cotton blankets and socks were used for the control group. In addition to the cotton blankets and socks, electric blankets were used for the patients in the intervention group. In accordance with the literature, the temperature of the electric blanket was set at 38 °C (Celsius) at the beginning and increased to a maximum of 40-41 °C based on the patient's body temperature.

Application of ice to the incision site: Studies have reported that the cooling effect of ice packs is higher than that of cooled gel packs. In the intervention group, an ice pack was applied to the incision site for pain control in addition to active external warming. Ice packs at 0-5 °C with external dimensions of 160 × 91 × 34 mm and a filled weight of 363 g that were kept in the fridge were used for ice application. In this study, ice packs were applied in the first 12 postoperative hours for 20 minutes every 2 hours, and a parallel pain assessment was performed.

Measurements of body temperature, analgesic consumption, and pain level were made to evaluate the effectiveness of active external warming and ice application. The measurements and follow-up of the patients in the study and control groups in the ICU were carried out by these investigators.

Intervention

Other:
• Active external warming
In this study, methods used routinely in the Intensive Care Unit (ICU) such as cotton blankets and socks were used for the control group. In addition to the cotton blankets and socks, electric blankets were used for the patients in the intervention group. In accordance with the literature, the temperature of the electric blanket was set at 38 °C (Celsius) at the beginning and increased to a maximum of 40-41 °C based on the patient's body temperature .
• Ice application
In the intervention group, an ice pack was applied to the incision site for pain control in addition to active external warming. Ice packs at 0-5 °C with external dimensions of 160 × 91 × 34 mm and a filled weight of 363 g that were kept in the fridge were used for ice application. To prevent direct contact of the ice pack with the patient's skin, the ice pack was wrapped in a thin cotton sheath.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain score	McGill Pain Questionnaire Short-Form was used for pain assessment. The Verbal Pain Scale, contained in the McGill Pain Questionnaire Short-Form, measured pain intensity at the four-hour mark rating pain of 0 - 5 with 0 = no pain, 1 = mild pain, 2 = discomforting pain, 3 distressing pain, 4 = horrible pain and 5 = excruciating pain.	Pain scoring was initiated when the patient was extubated and until the postoperative 48th hour were recorded
Primary	Analgesic consumption (mg)	Algesic consumption: The analgesic consumption of the patient was evaluated with the analgesics used until the postoperative 48th hour. The amount of analgesic administered to the patient was recorded in milligrams.	Analgesic consumption was started to be recorded when the patient was admitted to the intensive care unit, and until the postoperative 48th hour were recorded
Primary	Body temperature degree	The patient's body temperature was recorded in degrees Celsius.	The patient's body temperature was measured in the first four hours postoperatively
