Treatment of Procedural Pain Associated With Turning in Patients With Mechanical Ventilation

Study Overview
=================
Brief Summary
-----------------
Background: Few studies have addressed the situation of procedural pain and the use of preemptive analgesia for turning in patients under mechanical ventilation. Aim: Evaluation effect of preemptive fentanyl on the incidence of pain during turning maneuvers in critically ill patients under mechanical ventilation. Design: Single-center clinical trial, national, randomized, double-blind, with a parallel group, and two arms of treatment: saline placebo and fentanyl. Primary Endpoint: Incidence of pain during the turning procedures that are carried out by nurses measured by means of the Behavioral Pain Scale (BPS). Study Population: Critically ill patients, age > 18 years, admitted to ICU and expected to require mechanical ventilation for at least 24 h. Sample Size: 80 patients divided into the two groups (40 patients each). Statistical Analysis: A preliminary descriptive analysis will be carried. Later, results of primary end point will be comparing after the eventual corrections of corresponding variables using a multivariable approach. The AUC variable will be analyzed by a t-test for unpaired data. A second analysis using a multivariate approach will be carried out for those factors considered as clinically relevant in relation to pain and therefore a logistic regression will be used. Ethical Considerations: The study will be strictly conducted following the Declaration of Helsinki and the protocol and Standard Operating Procedures (SOPs) to ensure compliance with the Good Clinical Practice (GCP) standards. It is the responsibility of the researcher to obtain the valid informed consent from the guardian / legal representative, as the patient's condition will not allow to consent. Before obtaining the consent the investigator will explain to each guardian / legal representative the nature of the study, its purpose, the procedures, the estimated duration, the potential risks and benefits associated with the participation, as well as any inconvenience that this may involve. Duration of Treatment: The treatment has a maximum duration of 60 min for each patient. The follow-up includes visits and has duration of 6 consecutive days. Safety Assessment: Potential side effects of treatments will be recorded. Frequent adverse effects of fentanyl administration include respiratory depression, apnea, muscle rigidity, bradycardia and transient hypotension.

Primary Purpose: Prevention
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: Placebo<br>Placebo Treatment: A sterile sodium chloride injection 0.9% 10 ml | Other: Placebo<br> <br> |
| Experimental: Fentanest<br>For this study Fentanest doses were adjusted based on published guidelines from the values recommended media to a whole number and differentiating two groups of patients (multiple trauma / surgical or medical) The maximum dose is 100 mcg Fentanest. The multiple trauma patients / surgical 1.5 mcg / kg and in medical patients 1.0 mcg / kg were given a single bolus Fentanest / Placebo by type of patient (surgical / multiple trauma or physician) 5 'before turning mobilization with personal hygiene. The bolus is given slowly (30'') intravenously, to be preferred by a peripheral without vasoactive drugs (only with fluid therapy). Pharmaceutical form: Sterile solution for injection. Each mL of injectable solution contains the equivalent of 0.05 mg of Fentanest; Excipients: sodium chloride and water for injection. | Drug: Fentanyl<br> <br> |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the incidence of pain at the beginning and end of rotation | Participants will be evaluated at the beginning and the end of rotation, an expected average of 5 minutes. The evaluation of the change in the incidence of pain will be done calculating the mean between the beginning and the end of rotation. | Expected average of 5 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area under the curve (AUC) of incidence of pain (BPS) during mobilizations with spin |  | Since the end of the turn until 30 minutes after |
