Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was conducted to understand how training given to patients before and after open-heart surgery affects their reactions during intubation (when a breathing tube is inserted), their agitation levels, and the time it takes to remove the breathing tube.

Study Design

The research followed a quasi-experimental design, meaning patients were divided into two groups:

Experimental Group - Received special training before and after surgery. Control Group - Received standard hospital care without additional training. Key Variables Independent Variable (What was changed): The training given before and after surgery.

Dependent Variables (What was measured):

Patient reactions during intubation Agitation levels Time taken to remove the breathing tube Study Hypotheses Patients who received the training would show different reactions compared to those who did not.

1.1. The trained group would show fewer negative reactions during intubation. Patients who received the training would have different agitation levels compared to the control group.

2.1. The trained group would be less agitated. The time taken to remove the breathing tube would be different between the two groups.

3.1. The trained group would have their breathing tube removed faster. Where and When Was the Study Conducted? The research took place at Bezmialem Vakif University Hospital in Istanbul in the cardiovascular surgery department, between October 10, 2022 - January 7, 2023.

Participants The study initially considered 123 patients who had undergone open-heart surgery during this period.

Patients were selected based on certain health conditions and criteria (age, no chronic respiratory disease, type of surgery, etc.).

After applying these criteria, 30 patients (15 in each group) were included in the final study.

How Were Patients Selected? To ensure fairness, patients were randomly assigned to either the experimental or control group.

A computer-generated random list was used to assign them. Who Was Included in the Study? Patients who had Coronary Artery Bypass (CABG), Aortic Valve Replacement (AVR), or Mitral Valve Replacement (MVR) surgery.

Patients aged 45-70 years old. Who Was Excluded? Patients with chronic respiratory disease (as it could affect intubation time). Patients who had previous open-heart surgery (as prior experience could influence their reaction).

Patients who did not speak Turkish or had cognitive issues. Patients with severe psychiatric conditions. Data Collection \& Training Process

Before the surgery:

Patients were asked about their age, gender, smoking habits, medical history, and other factors.

Their anxiety levels were measured using a scale from 0 to 10 (0 = No anxiety, 10 = Extreme anxiety).

Training for the experimental group:

A special 40-50 minute training session was given a day before surgery. The training included breathing techniques, relaxation methods, and information about what to expect during recovery.

Family members were also involved.

After the surgery:

Patients were sedated as part of hospital protocol and then observed when they first woke up in the Intensive Care Unit (ICU).

The trained group received additional therapeutic communication techniques when they first woke up to help them stay calm.

The control group received only standard hospital care. Four hours after waking up, all patients were evaluated for their agitation levels and reactions to intubation.

How Were Reactions Measured? Richmond Agitation Sedation Scale (RASS ) - This measured how restless or calm the patient was.

Observation of Intubation Reactions - The research team noted behaviors such as:

Trying to pull out the breathing tube Biting the tube Facial expressions (like frowning or grimacing) Grabbing bed sheets Moving legs restlessly Breathing in sync with the ventilator Each behavior was scored from 0 (Not observed) to 4 (Strongly observed). A higher score meant the patient was more uncomfortable with intubation.

Results General reactions to intubation (measured with a scale) were similar in both groups.

However, when specific behaviors were examined, the control group had more visible distress:

More frowning and wrinkled facial expressions (p=0.030). More grabbing of bed sheets (p=0.013). There was no significant difference in agitation levels between the two groups. The time taken to remove the breathing tube was also not significantly different between the two groups.

Conclusion The special pre- and post-surgery training helped patients remain more comfortable during intubation, reducing visible signs of distress.

However, the training did not significantly impact overall agitation levels or the time needed to remove the breathing tube.

This suggests that therapeutic communication techniques may improve patient comfort but do not necessarily speed up the recovery process.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Trained group

Pre-Surgery:

Patients received a special training including therapeutic communication techniques.

The training was prepared by reviewing the literature and integrated into hospital practices.

One day before surgery, the patient and patient's relatives were trained in a session lasting 40-50 minutes.

All stages of the training were monitored using the "Preoperative Training Checklist ".

Postoperative:

When the patients were taken to the intensive care unit, sedation was applied again at the first awakening according to the hospital protocol.

After the effect of sedation wore off and the patient was conscious but still intubated, therapeutic interventions were performed.

This process was done with the "Postoperative Education Checklist " prepared based on the literature.

Data Collection:

4 hours after the patients woke up, by the researcher: RASS (Richmond Agitation Sedation Scale) was applied. Intubation Reactions Form was filled. The time to come out of intubation was recorded.

Group Type EXPERIMENTAL

THERAPEUTIC APPROACH TRAINING

Intervention Type BEHAVIORAL

This study focuses on pre- and post-operative training for open-heart surgery patients, aiming to reduce anxiety, agitation, and discomfort during intubation and recovery.

In the meeting phase, the nurse introduces herself, explains the research, and obtains written/verbal consent. The patient's anxiety level is assessed.

In the study phase, patients are informed about the surgical process, breathing exercises, Intensive Care Unit conditions, and postoperative care. They are encouraged to express fears and concerns to improve psychological preparedness.

Key topics include:

Fasting before surgery Breathing exercises to ease extubation Use of mechanical ventilation Intensive Care Unit environment \& pain management Early mobilization \& recovery timeline Patients receive guidance on their role in recovery, ensuring better adaptation and reduced distress post-surgery.

Non-training group

Preoperative No special training was given to the control group. Patients were only subjected to routine hospital procedures.

Postoperative:

Standard hospital protocol was applied when the patients were admitted to the intensive care unit.

Sedation was applied again, but no additional therapeutic intervention was performed.

Patients received only routine nursing care.

Data Collection:

4 hours after patients woke up, by the investigator: RASS (Richmond Agitation Sedation Scale) was administered. Intubation Reactions Form was completed. The time to come out of intubation was recorded.
