About this study

Official title: Efficacy of Perioperative Hypothermia Prevention Measures in Osteosynthesis. Clinical Trial With Control Group and Validation Into Spanish of the "BEDSIDE SHIVERING ASSESSMENT SCALE".

Randomized control study with a control group and 90 days follow-up for assessing the decrease in the incidence of inadvertent perioperative hypothermia in the osteosynthesis surgical patients after the application of a bundle in prevention measures during the perioperative period, assessing thermal comfort, tremors (validation into spanish a tremors assessment scale), surgical site infections and readmissions.

Read the detailed description

Introduction: Perioperative hypothermia, defined as a core body temperature lower than 36 ºC (Celsius degree), is a major problem in the surgical setting. Between 20 and 70% of patients may develop it unintentionally, affecting, to varying degrees, patient safety. Since the beginning of the 90's, serious complications associated with its appearance have been described: infection, alteration of thermal comfort, shivering and increased readmissions.

Objective: to identify whether the application of a bundle of prevention measures against the occurrence of Inadvertent Perioperative Hypothermia in the osteosynthesis surgical patient decreases the incidence of perioperative hypothermia. Secondary objectives to identify the prevalence of inadvertent perioperative hypothermia in the osteosynthesis surgical patient, to determine if the application of a bundle of preventive measures against the occurrence of inadvertent hypothermia decreases the incidence of postoperative or postanesthetic tremors in the surgical patient, to determine if the application of a bundle of preventive measures against the occurrence of inadvertent hypothermia increases the thermal comfort of surgical patients in the immediate postoperative period, to identify the impact of the application of a bundle of prevention measures against the occurrence of inadvertent perioperative hypothermia in the osteosynthesis surgical patients in relation to surgical site infection up to 90 days postoperative follow up and hospital readmissions associated with the occurrence of infection up to 90 days from surgery, to identify possible variables related to the incidence of surgical site infection at 90 days in the hypothermic patient with respect to the normothermic patient and to validate the Spanish translation of the "BEDSIDE SHIVERING ASSESSMENT SCALE" for tremors in the post anesthesia care unit (PACU).

Methodology:First phase: validation and adaptation to Spanish of the "BEDSIDE SHIVERING ASSESSMENT SCALE" (measurement of tremor in patients) with a prospective study with 40 patients.

Second phase: a controlled Randomized Clinical Trial (RCT) will be carried out, in which the intervention group (IG) will implement the bundle of prevention measures against the appearance of perioperative hypothermia and the control group (CG), the usual treatment with textile blankets will be carried out at the patient's request.

A stratified randomization will be carried out to guarantee an equal distribution by groups in the variables type of operating room, type of anesthesia, anesthetic risk (ASA Physical Status 3, maintaining an equal or similar cluster in both the IG and the CG.

124 osteosynthesis trauma surgery patients will be randomized, 62 in each group.

To the intervention group, a bundle of hypothermia prevention measures will be applied before the start of anesthesia, based on: pre-warming of the patient for 10 minutes with a convective heating system (forced air blankets) which will be maintained during surgery and immediate postoperative period, intravenous perfusions will be warmed to 38 Celsius degree(ºC) and the environmental temperature will be controlled at 21 Celsius degree(ºC) . To the control group, will perform the usual treatment with textile blankets on patient demand as usual.

This study will be carried out at the Economic Health Assistance for Employees and Laborers hospital (ASEPEYO) in Barcelona (Spain) which is an accidents at work hospital. The target population is all patients undergoing osteosynthesis trauma surgery of the upper limb, lower limb, and spine.

Expected results: an improvement in patient safety is expected with a decrease in the incidence of perioperative hypothermia, shivering, with an improvement in postoperative thermal comfort.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. incidence of perioperative hypothermia

    Core temperature assessed with 3M (registered trademark) Spot-on dual sensor thermometer. It will be attached to the frontal region of the patient in awake and anesthetized patient. Validated in the USA by Eshragui et al. in 2014. Compared with pulmonary artery catheter (gold standard), difference of 0,5 ºC; validated in Spain by Gómez-Romero et al. in 2019; 289 repeated measures, Spearman correlation coefficient (r) 0.82[95% Confidence Interval (CI)] 0.77-0.85 with p<0.001, with an interrelation coefficient (ICC) of 0.88 (95%CI 0.85-0.90).

    Bland-Altman repeated measures analysis for Spot-On and Swan Ganz catheter revealed a bias (SD) [95% CI] of 0,21°C (0.34) [-2.27 to 2.71].

    Kollmann-Camaiora et al. validated it in 2019 respect to esophageal temperature probe measurement.

    Bland Altman Plot, Pearson Correlation (PC) and intraclass correlation coefficient with 400 repeated measures: PC 0.82, Bias of -0.27(95%CI [-0.61-0.55], and ICC 0.90 (95%CI [0.88-0.92.])

    Measured: perioperative period (since OR arrival until PACU Discharge)

  2. incidence of postoperative or postanesthetic tremors in the surgical patient.

    BEDSIDE SHIVERING ASSESMENT SCALE (BSAS): ordinal scale that evaluates the presence or absence of postoperative or postanesthetic tremors. Created in 2008 by Badjatia et al. it consists of 4 levels, with a minimum value of 0 and a maximum value of 3;

    Measured: postoperative period (since Postanaesthesia care unit arrival until the first documented vital sign registration)

  3. incidence of postoperative or postanesthetic tremors in the surgical patient. assessment of thermal comfort in postanesthesia care unit

    Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Scale endorsed by the International Organization for Standardization 10551:2019. Scale for measuring indoor thermal comfort.

    It consists of 7 Likert-type items, where the patient is asked the sensation of cold or heat before discharge from the PACU; the center of the scale is thermal neutrality (0), the left pole registers cold, and the minimum score is -3 and the right pole evaluates heat and the maximum value is +3.

    Measured: postoperative period (since Postanaesthesia care unit (PACU) arrival until PACU discharge)

On the ClinicalTrials.gov record for NCT05469958, which also lists 29 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
