About this study

Official title: The Effect of Bed Bath Given to Intensive Care Unit Patients With Auditory Hypnosis on Physiological and Comfort Parameters: a Randomized Controlled Experimental Study

Intensive care units (ICUs) are specialized units where complex life-saving treatment and care activities are performed. Due to the treatment procedures performed in these specialized units, a large number of tools/equipment/devices/cables (endotracheal tubes, monitor cables, hemodialysis machines, mechanical ventilation, etc.) are placed on critically ill patients. These treatment devices restrict the movement of patients, creating obstacles to the independent performance of basic human needs such as personal hygiene. One of the individual hygiene practices frequently applied in ICUs is bed bathing. The application of bed bathing in ICUs varies according to institutional and clinical policies. In addition to its beneficial effects such as preventing infection, accelerating blood circulation, providing comfort and relaxation, etc., bed bathing also carries the risk of having a negative effect on physiological parameters. Eliminating or minimizing this risk is one of the primary care objectives of intensive care nurses. In this regard, it is crucial that bed baths, which are considered a routine nursing activity in ICUs, are performed in accordance with specific standards and protocols. In recent years, there has been an increase in the use of certain non-pharmacological care interventions in ICUs. One such intervention is auditory suggestion. Auditory suggestion refers to messages delivered through hearing to facilitate the adoption of specific thoughts, feelings, or behaviors. This method includes music, verbal suggestion, nature sounds, and other auditory stimuli that are believed to have the potential to influence the subconscious. In recent years, auditory suggestion has been integrated into the treatment processes of critically ill patients, particularly in intensive care units. This method is applied to reduce patients' stress, control pain, and support hemodynamic stability. Research has provided strong evidence supporting the physiological and psychological effects of auditory suggestion on both adult and pediatric patients. On the other hand, maintaining the patient's physiological parameters under control and increasing their comfort level while administering bed baths in the ICU are desired outcomes of nursing care. Based on this, the study was designed as a randomized controlled trial to investigate the effects of bed baths administered with auditory suggestion on physiological and comfort parameters in intensive care patients. The study, which will be conducted with a total of 66 ICU patients meeting the sample selection criteria, will apply the "bed bath protocol with auditory suggestion" to the study group and routine bed baths to the control group (only once). The study data will be collected using the "Patient Information Form" and the "Physiological and Comfort Parameters Monitoring Form" (data from the form will be collected and recorded before the bath, immediately after the bath, and 30 minutes after the bath). The study data will be analyzed using appropriate statistical methods.

Read the detailed description

Intensive care units (ICU) are specialized units where complex life-saving treatment and care activities are performed. Due to the treatment interventions applied in these special units, a large number of tools/equipment/devices/cables (intubation tube, monitor cables, hemodialysis device, mechanical ventilation, etc.) are placed in critically ill patients. These treatment equipments restrict the movement of patients and hinder the independent fulfillment of the most basic human needs such as personal hygiene. One of the most common individual hygiene practices in ICUs is bed bathing. At the same time, in addition to the beneficial effects of bed bathing such as preventing infection, accelerating blood circulation, providing comfort and relaxation, etc., there is also a risk of negative effects on physiological parameters. Elimination or minimization of this risk is one of the primary care-giving goals of the intensive care nurse.

Considering the duties, authorities and responsibilities of intensive care nurses, ensuring the safety and comfort of the critical patient in the ICU should be the primary goal of the nurse. In this direction, some non-pharmacological applications can be utilized to prevent the risk of deterioration in the patient's physiological parameters and to increase his/her comfort during bed bathing, which is frequently applied to critically ill patients in the ICU and seen as an ordinary procedure.

One of these applications, the effects of which have been investigated on critically ill patients in ICU in recent years, is auditory suggestion. Auditory suggestion refers to verbal or auditory messages given through hearing to facilitate individuals to adopt certain thoughts, feelings or behaviors. This method includes music, verbal suggestion, nature sounds and other auditory stimuli that are thought to have the potential to influence the subconscious mind.

Recent studies have shown that auditory suggestion can play an important role in improving the physiological and psychological parameters of critically ill patients, especially in intensive care units (ICU). Clinical applications of auditory suggestion often include music therapy, white noise, nature sounds, meditation music and audio recordings with subliminal messages. Music therapy is the most common and most researched form of auditory suggestion. In the mid-20th century, music therapy began to be used as an adjunct therapy in the treatment of various psychological and neurological disorders. However, in modern medicine and psychology, the physiological effects of auditory suggestion are being taken more into account. Studies on the use of auditory suggestion, especially in intensive care units, show that this method can increase the hemodynamic stability of patients and reduce their stress levels.

With the sense of hearing, which is the last lost sense of hearing of human beings, the physiological and comfort parameters of the patients can be positively changed by the bed bath given to critically ill patients accompanied by auditory suggestion. Since patients who cannot communicate verbally have no control over themselves and their environment, it is known that talking with these patients has a therapeutic value. Accordingly, the aim of this study was to examine the effect of bed bath given to intensive care unit patients accompanied by auditory suggestion on physiologic and comfort parameters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bed Bath With Auditory HypnosisOther

    In the bed bath protocol accompanied by audio suggestion, a 30-60 minute audio recording containing audio suggestions specific to the ICU patient will be prepared with the support of a specialist hypnotherapist. This audio recording will include the following messages: - The purpose of the bed bath, - Procedures to be performed during the bed bath, - The benefits of the bed bath, - Feeling safe during the bed bath, - Improvement in physiological parameters and comfort levels after the bed bath.

    While it is noted that auditory suggestion typically lasts 30-60 minutes, even a 15-minute auditory suggestion has been reported to provide benefits.

What is being measured

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

  1. Intensive Care Pain Observation Scale

    It is a scale used specifically for the assessment of pain in unconscious patients receiving mechanical ventilation treatment in ICU. The scale consists of four parameters to assess facial expression, body movements, ventilator compliance and muscle tension. Each parameter is scored between 0 and 2. The minimum score is 0 and maximum score is 8. Scores between 0 and 4 show mild to moderate pain and scores between 5 and 8 show severe pain. Since pain is one of the most important markers of comfort, investigators planned to use this scale for criterion-related validity. It is expected that as pain increases, comfort level decreases.

    Measured: Before bed bath, immediately and 30 minutes after the bed bat

  2. Comfort Behaviors Checklist

    The Comfort Behaviors Checklist consists of 30 behavioral indicators. In addition, Kolcaba suggests that if the list is the only measurement tool that measures comfort, the individual should give a numerical score to pain and comfort so that comfort can be objectively evaluated. Questions 2, 3, 5, 7, 8, 8, 9, 11, 12, 13, 19, 20, 21, 22, 24, 25, 27 are reverse coded. The list is scored on a 4-point Likert scale. When the list is completed, questions that are not applicable to the individual are given 0 points. The total number of questions answered is multiplied by 4 to obtain the possible score. The scores for all questions are calculated by reversing the questions, and the raw comfort score is obtained. Finally, the possible comfort scores are divided by the raw scores to obtain a decimal number. The decimal part of the obtained score is expressed as a two-digit number. The total score is calculated and then standardized to a scale of 0 (lowest comfort) to 120 (highest comfort).

    Measured: Before bed bath, immediately and 30 minutes after the bed bath

  3. Change in Heart Rate

    Heart rate (beats per minute) will be measured before bed bath, immediately after, and 30 minutes after.

    Measured: Baseline (pre-bed bath), immediately post-bed bath, and 30 minutes post-bed bath

  4. Change in Systolic and Diastolic Blood Pressure

    Systolic and diastolic blood pressure (mmHg) will be measured at three time points: before, immediately after, and 30 minutes after bed bath.

    Measured: Baseline, immediately post, and 30 minutes post-intervention

  5. Change in Respiratory Rate

    Respiratory rate (breaths per minute) will be assessed at baseline, immediately after, and 30 minutes after the bed bath.

    Measured: Baseline, immediately post, 30 minutes post

  6. Change in Body Temperature

    Body temperature (in degrees Celsius) will be recorded at three time points: before, immediately after, and 30 minutes after the bed bath.

    Measured: Baseline, immediately post, 30 minutes post

  7. Change in Peripheral Oxygen Saturation (SpO₂)

    SpO₂ will be measured using pulse oximetry before and after the bed bath at designated time points.

    Measured: Baseline, immediately post, 30 minutes post

  8. Change in Blood pH

    Blood pH will be assessed through arterial blood gas sampling at three time points.

    Measured: Baseline, immediately post, 30 minutes post

  9. Change in Partial Pressure of Oxygen (pO₂)

    pO₂ will be measured through arterial blood gas analysis at three time points.

    Measured: Baseline, immediately post, 30 minutes post

  10. Change in Partial Pressure of Carbon Dioxide (pCO₂)

    pCO₂ values will be obtained via arterial blood gas analysis at the specified intervals.

    Measured: Baseline, immediately post, 30 minutes post
