There were not enough numbers in all boxes so statistical analyses not appropriate to assess for this title.

Between two groups duration of hospitalizations were not statistically different including parameters of Total Duration of Hospitalization (p=0.879), Preoperative Duration of Hospitalization (p=0.601), Postoperative Duration of Hospitalization (0.995) and Duration of ICU Hospitalization (0.346).

In our study 11 patients from intervention group and 16 patients from control group needed ICU follow up after surgery. (p=0.348)

These data is not result of standardized (like in the literature suggests) costs data.These data made by our patients data system which can calculate goverments payments fees, etc for any procedure performed to any patient. (intervention based data ) (p=0.524)

There were not enough numbers in all boxes so statistical analyses not appropriate to assess for preoperative and peroperative warming. Postoperative warming choices were significiantly different between two groups as excepted because of study protocols contents.(p<0.001)

Preoperative Warming which is not our center's traditional method for routine maintaining normothermia procedures, performed for only and to all of intervention group patients . For this reason it is not inculed to this analyze table.

During the preoperative patient's approval period, if surgical site is predicted as contaminated and dirty, these patients not appropriate for study. (preoperatively) In 2 patients preoperatively appropriate was found that peroperatively they had closed microperforation of tumor.Though minimal contamination detected perioperatively and there were not any clinical findings of infection, they accepted as contaminated.

There were not enough numbers in all boxes so statistical analyses not appropriate to assess.

For ASA scores groups were homogeneous. (p=0.943) ASA 4,5,6 is not shown because of the study inclusion criterias. (ASA which has known as American Society of Anesthesiologists Physical Status, min. 1 and max. 6). Definitions: ASA 1-Normal healthy patients, ASA 2-A patient with mild systemic disease. ASA 3-A Patient with severe systemic disease, ASA4-A patient with severe systemic disease that is a constant threat to life, ASA5-A moribund patient who is not expected to survive without the operation, ASA6-A declared brain-dead patient whose organs are being removed for donor purposes)

For NNISS scores groups were homogeneous. (p=0.875) NNISS Score which has known as The National Nosocomial Infections Surveillance System Scoring System used for prediction of the risk of Surgical Site İnfections (SSI).The NNIS basic SSI risk index is composed of the following criteria: American Society of Anesthesiologists score of 3, 4, or 5 (>2 takes one score; wound class( contaminated or dirty takes one point; and duration of surgery (There are percantile times defined and above 75 percantile, score takes one point) NNISS Score may be 0 to 3, and SSI risks were increased by score.

For SENIC scores groups were homogeneous. (0.581) This Scoring system has known as Study on Efficacy of Nosocomial Infection Control (SENIC) project's SSI Risk Scoring System (Min. 0 to max. 4 points may be calculated , risk of SSI incerases by score ). 4 criterias include duration of surgery (>2 hours), abdominal surgery, wound class( contaminated or dirty takes one point) and comorbidities (>2) which is any of them is one points.

Because of the participants who in each score (0-4) was not enough to analyse statisticaly, participants divided into two groups. (<3 and ≥3)

There were not enough numbers in all boxes so statistical analyses not appropriate to assess for this title. Buy for classifaciton of the comobidities, Elixhauser Classification used for standart data presentation.

In our study 11 patients from intervention group and 16 patients from control group needed ICU follow-up after surgery. For this reason ICU patient's measurements were not including service data.

Also these measurements were not including 300, 360, 420, 480, 540, 600 minutes data.Because most of the patients operation times are less than 6 hours.

Our study's main outcome which is SSI is significiantly different between two groups.(p=0.044)

ASEPSIS Wound Scoring System used in our study. ASEPSIS postoperative total Points (p=0.029) was different between two groups. Simply points are given for the need for Additional treatment, the presence of Serous discharge, Erythema, Purulent exudate, and Separation of the deep tissues, the Isolation of bacteria, and the duration of inpatient Stay (ASEPSIS). (min. is 0 points and max. doesn't have any limit but 0-10 points is succesful, 11-20 points is impaired healing and 21-30 points is mild, 31-40 is moderate, >41 points is severe SSI.)

Within the surgery day, from patient bed through the operating room to PACU or ICU or back to patient bed.

With these results our intervention group's maintaining normothermia rates were higher respectively. ( p=0.001) For each patients around 11 temperature measurement had been made according to the operation time . If any measurement of any patients was <36 ºC , that patient accepted as hypothermic. (Failure to maintain normothermia)

Patients and their results assessed on the basis of intention to treat per protocole.

Perioperative management and warming was performed according to a standard normothermia protocol with active prewarming.
