About this study
Endotracheal suctioning is a common procedure used to remove secretions from the airways of patients receiving mechanical ventilation. Although this procedure is necessary for respiratory care, it may cause pain and discomfort. Assessing pain can be challenging in patients who cannot communicate verbally, making appropriate pain assessment and management particularly important.
Natural sounds, such as sounds from nature, may offer a non-pharmacological approach to reducing procedural pain. Selecting sounds based on family members' knowledge of a patient's preferences may provide a more personalized approach, while standardized natural sounds may offer a consistent alternative. Noise reduction may also help limit unnecessary environmental sound exposure during the procedure.

This four-arm randomized controlled trial will compare the effects of family-proxy-selected natural sound therapy, standardized natural sound therapy, noise reduction, and the designated control condition on procedural pain during endotracheal suctioning in non-communicative adults receiving mechanical ventilation.
Eligible participants will be randomly assigned to one of the four study groups. Pain will be assessed using a prespecified instrument appropriate for non-communicative critically ill patients. The study will compare pain outcomes across the groups to determine whether family-proxy-selected natural sounds, standardized natural sounds, or noise reduction are associated with lower procedural pain.
The findings may help inform non-pharmacological approaches to procedural pain management in mechanically ventilated adults who cannot communicate their pain verbally.
Read the detailed description
Background and Rationale
Endotracheal suctioning is frequently performed in mechanically ventilated patients to maintain airway patency and remove accumulated respiratory secretions. Despite its clinical importance, suctioning can be associated with pain and physiological stress. Patients who are unable to communicate verbally may be particularly vulnerable because they cannot directly describe the intensity or nature of their pain.
Pain assessment in non-communicative critically ill patients therefore requires systematic observation using an appropriate validated behavioral pain assessment instrument. In addition to routine clinical pain management, non-pharmacological interventions may provide supportive strategies for reducing procedural pain.
Natural sound therapy is a potential non-pharmacological intervention that may help reduce distress during painful or uncomfortable procedures. However, the effect of natural sounds may depend on the type of sound used and its relevance to the individual patient. Family members may provide useful information about a patient's familiar sounds and preferences when the patient cannot communicate these preferences directly. Family-proxy-selected natural sounds may therefore offer a personalized approach, whereas standardized natural sounds provide a more uniform intervention that can be delivered consistently across participants.
Environmental noise reduction represents a separate approach that focuses on minimizing unnecessary sound exposure rather than introducing therapeutic sounds. Comparing these strategies may help clarify their respective effects on procedural pain during endotracheal suctioning.
Study Objective
The primary objective is to compare procedural pain during endotracheal suctioning among non-communicative, mechanically ventilated adults assigned to family-proxy-selected natural sound therapy, standardized natural sound therapy, noise reduction, or the protocol-defined control condition.
The study will evaluate whether these approaches differ in their effects on observed procedural pain. The results may contribute to evidence-based nursing care for critically ill patients who cannot communicate verbally.
Study Design
This study is a four-arm randomized controlled trial involving non-communicative adults receiving mechanical ventilation who require endotracheal suctioning. Eligible participants will be randomly allocated to one of four groups according to the study's randomization procedure.
The four groups will be defined as follows:
- Family-Proxy-Selected Natural Sound Therapy Group: Participants will receive natural sound therapy using sounds selected by a family member or designated proxy based on the proxy's knowledge of the patient's preferences or familiarity with particular sounds.
- Standardized Natural Sound Therapy Group: Participants will receive a predefined natural sound intervention selected by the research team according to a standardized protocol.
- Noise Reduction Group: Participants will receive the protocol-defined environmental noise reduction intervention during the relevant procedural period. The intervention will focus on reducing unnecessary environmental sound exposure.
- Control Group: Participants will receive the standard care specified in the study protocol without the additional intervention assigned to the other groups.
The precise intervention procedures, timing, duration, sound delivery method, and control condition will follow the finalized study protocol.
Study Population
The study population will consist of adults receiving invasive mechanical ventilation who are unable to communicate their pain verbally and require endotracheal suctioning. Participants will be screened against prespecified eligibility criteria before enrollment.
Outcome Assessment
The primary outcome will be procedural pain associated with endotracheal suctioning. Pain will be assessed using the behavioral pain assessment instrument specified in the protocol and appropriate for non-communicative critically ill adults. Assessments will be conducted at prespecified time points in relation to the suctioning procedure.
The study will compare pain scores across the four randomized groups according to the prespecified statistical analysis plan. Any secondary outcomes, additional physiological measurements, assessment time points, and safety assessments will be defined in the finalized protocol and registered in the appropriate outcome fields.
Potential Significance
This study will provide a comparative evaluation of three non-pharmacological approaches to procedural pain management in mechanically ventilated adults who cannot communicate verbally. By examining personalized natural sound therapy, standardized natural sound therapy, and environmental noise reduction within a randomized design, the study may help identify approaches that can be considered as supportive components of nursing care during endotracheal suctioning.
These interventions are intended to be evaluated within the context of appropriate routine clinical care and should not replace indicated analgesia, established pain assessment, or other necessary clinical management.

What is being measured
The primary outcome is the main question the study is designed to answer.
Procedural Pain Score During Endotracheal Suctioning
Procedural pain will be assessed using the Critical-Care Pain Observation Tool (CPOT), a behavioral pain assessment instrument for critically ill patients who cannot communicate verbally. The CPOT score will be recorded during endotracheal suctioning according to the study protocol. Scores will be compared among the four randomized groups to evaluate differences in procedural pain. The instrument will be administered and scored according to its established instructions.
Measured: 5 minutes before suctioning (baseline), during suctioning (at the point of greatest observed pain-related behavior), and 5 minutes after completion of suctioning.
