Postoperative Anxiety

This study evaluates the effectiveness of Virtual Reality (VR) as a non-pharmacological intervention to reduce intraoperative anxiety and postoperative agitation in elderly patients undergoing elective hip arthroplasty under regional anesthesia. Half of the patients will experience an immersive, calming nature-based VR environment during the surgery, while the control group will receive standard care.

The purpose of this clinical trial is to learn whether the use of a "cold and arm sling elevation pillow" affects anxiety and comfort levels in children aged 7-12 years undergoing surgery for upper extremity fractures. The main questions it aims to answer are: * Does the use of a cold and arm sling elevation pillow reduce postoperative anxiety levels in children? * Does the use of a cold and arm sling elevation pillow increase postoperative comfort levels in children? Researchers will compare the experimental group (using the specially designed cold and arm sling elevation pillow) with the control group (receiving standard clinical care, including standard pillows and separate ice packs) to see the effects of the integrated pillow on anxiety and comfort. Participants will: * Receive education before surgery based on their randomly assigned group (experimental or control), * Use the assigned elevation and cold application method for the first 24 hours following surgery, * Complete anxiety and comfort assessment scales at four different time points: before the intervention, just before surgery, 6 hours after surgery, and at the time of discharge.

Postoperative complications after surgical procedures, including following total knee arthroplasty (TKA), have a negative impact on the health and well-being of surgical patients. Older adults (≥65 years) are particularly vulnerable to postoperative complications and their associated morbidities due to the biological aging process. Older adults comprise nearly half of surgical patients worldwide, and this number is expected to increase in the next 10-20 years as the aging population continues to grow. TKA is the most common procedure undergone by older adults, and the rate of TKA procedures is also expected to rise. Despite perioperative guidelines and protocols to prevent postoperative complications, the prevalence of postoperative complications following TKA is approximately 12%. Given these statistics, millions of older adults undergoing TKA may be at risk for postoperative complications and their associated morbidities in the coming decades. Therefore, additional interventions are needed to combat postoperative complications in this population. The body's natural response to surgery, also known as the surgical stress response (SSR), contributes to postoperative complications through complex mechanisms involving the autonomic nervous system (ANS). Increased sympathetic nervous system (SNS) activity, or the body's fight-or-flight response, causes dysregulation in feedback systems that regulate the stress response, potentially leading to poorer outcomes. Interventions, such as breathwork, that induce the parasympathetic nervous system (PNS), or the body's rest-and-digest response, have been shown to balance the ANS, regulate stress biology, and improve outcomes. This study will examine the feasibility of adding a breathwork intervention (Box Breathing), compared to an attention control, to standard perioperative care for older adults undergoing TKA. This study will also examine the proof of concept that Box Breathing, compared to an attention control, may help regulate the SSR by assessing an objective measure of stress-related biology, diurnal cortisol rhythm, and gathering self-report information on pain, anxiety, depression, and quality of recovery following TKA.

This study aims to evaluate the effects of virtual reality (VR) and eye mask (EM) applications on pain, anxiety, and physiological parameters during dressing after Coronary Artery Bypass Graft (CABG) surgery. Postoperative dressing procedures, especially after sternotomy, often cause significant pain and anxiety in patients. These issues can negatively impact recovery and increase the need for medication. Non-pharmacological interventions such as VR and EM may help reduce these symptoms. In this randomized controlled trial, 90 patients are divided into three groups: VR group, EM group, and a control group receiving standard care. Pain and anxiety levels are monitored baseline, immediately after, and 15 minutes after both the first and second dressing procedures. Physiological parameters are measured baseline, during, immediately after, and 15 minutes after both dressing procedures. Additionally, analgesic use is followed baseline and immediately after each dressing procedure. The study is conducted in a cardiovascular intensive care unit in Istanbul, Türkiye. It is expected that the findings will support the integration of VR and EM as effective, low-cost, and non-invasive options for postoperative care, improving patient comfort and healthcare quality.
