Abstract Introduction: Head injury is a global health problem that often resulted from traffic accidents, and has a serious impact on brain and nervous system function. One of the main symptoms of head injury is intense pain, which often affects patients' quality of life. Although pain medications are widely used, non-pharmacological interventions such as the Slow Deep Breathing (SDB) technique have been proposed as an effective alternative to reduce pain in head injury patients. This study was aimed to evaluate the impact of SDB on pain reduction in patients with head injury. Subject and Methods: This systematic review was conducted using the PRISMA method with journal searches in several databases such as Google Scholar and PubMed. The search focused on studies published between 2020 to 2024. Screened articles had to meet the inclusion criteria involving observational studies on SDB in head injury pain. In this systematic review, information was collected by highlighting key elements, including the population group, type of intervention measures, outcomes observed, and methodological approach chosen. Result: of the 425 journals identified, 95 articles were screened, and 4 journals met the criteria for further The results of the four studies showed that the SDB technique significantly reduced pain intensity in head injury patients. SDB helped lower heart rate, blood pressure, and improve blood oxygenation, all of which contributed to pain reduction. Conclusion: Slow Deep Breathing technique was shown to be effective as a non-pharmacological treatment for managing pain in head injury patients. Despite some limitations in sample size and study design, consistent results support the use of SDB as a complementary therapy in pain management. Future research is needed to inform the maximum therapeutic activity of SDB and explore the potential for combination with other therapies. Key words: Slow deep breathing, pain, head injury Introduction Head injury is one of the major health problems faced worldwide, including in Indonesia. According to a study reported by Riskesda in 2013, approximately 40. 6% of head injury cases in Indonesia were caused by traffic accidents. 1 Head injuries can have a serious impact on brain and nervous system function, resulting in morbidity, physical disability and death. 2,3 Head injuries are classified by severity, with mild, moderate and severe head injuries. 3 Many patients with head injuries report severe pain as one of the main This pain often interferes with the neuroanestesi Indones 2025. : 8Ae15 patient's quality of life and can affect the recovery 4,5 In its management, pharmacological approaches such as the administration of pain medications are often used. 5 However, the use of these medications is not always effective and may cause adverse side effects, especially if used over a long period of time. 6,7 As an alternative to pharmacological approaches, various nonpharmacological interventions have been proposed to help reduce pain in head injury patients. 8,9 One of the most promising methods is slow deep breathing (SDB) relaxation. SDB is a breathing technique that involves a slow and controlled inhalation of a deep breath, followed by a slow 8 The main purpose of this technique doi: https://doi. org/10. 24244/jni.

Impact of Slow Deep Breathing on Pain in Head Injury Patients: a Review Systematics is to create a deep state of relaxation in the body, can control the nervous system, and reduce the body's response to pain. 10 The SDB technique has several advantages over pharmacological First, this technique does not require special equipment, so it can be applied in health services and at home. Second, patients can do it according to their condition or pain, which means that this technique can be applied without the need for assistance from medical personnel. Third, this therapy does not cause side effects, so it is safe to be used for a long period of time. Several previous studies have shown that the SDB technique is effective in reducing pain intensity in various medical conditions, including patients with head injuries. 11 For example, a study conducted in 2020 reported that patients who applied the SDB technique during head injury treatment experienced a significant reduction in pain scale compared to those who did not use this technique. 12 Other studies have also shown that SDB can help reduce anxiety and stress, which are often related to pain intensity. 14 The mechanism of action of SDB is related to the activity of the parasympathetic nervous system, which is responsible for reducing the body's stress response, when a person takes a deep and slow breath, the heart rate slows down and blood pressure decreases, which creates a calming effect on the body, in addition, deep breathing also helps increase oxygenation of the brain and other body tissues, which can speed up the recovery process and reduce pain. 15 Through literature review and research findings, it is important to further understand how the SDB Technique can benefit patients with head injuries. This study was aimed to evaluate the impact of slow deep breathing on pain reduction in headinjured patients, as well as to understand the mechanisms underlying the effectiveness of this technique in reducing pain. With the existence of non-pharmacological interventions such as this, it is hoped that it can provide a safer, effective and affordable alternative in the management of pain in head injury patients. 16 Thus, the results of this study are expected to not only contribute to the management of pain in head injury, but also provide new insights into how non- pharmacological interventions can be applied more broadly in different medical contexts. Overall, the SDB technique has great potential to be an integral part of a holistic approach to pain management in head injury patients. the hope that comprehensive and continuous research on SDB techniques can become one of the leading nonpharmacological techniques in overcoming pain problems.

Of these, 30 articles were deleted because they were duplicates, while 200 articles were excluded because they did not meet the originality criteria. Furthermore, 50 articles were excluded because they were not relevant to the SDB technique, while another 50 articles were excluded because they did not review the evaluation of the technique. An additional 68 articles were eliminated after further review through abstracts and keywords. In addition, 20 articles were excluded due to inappropriate year of publication, and another 2 articles were excluded due to language not meeting the criteria . nly English and Indonesian were selecte. Thus, 4 articles met the final requirements to be analyzed in this systematic Discussion Consistent Research Results The results of the four studies analyzed in this review showed consistency in reducing the level of discomfort in patients with head trauma who were given SDB technique. Each study reported a significant reduction in pain scale after SDB intervention, indicating that this technique is effective as a non-pharmacological method in managing pain in head injury patients. The study conducted by Vita Insani Hospital Pematangsiantar showed a significant reduction in post-craniotomy patients, where SDB provided benefits not only to reduce subjective pain but also to reduce the need for pharmacological 2 Similar results were also found at Dr. Moewardi Hospital, where SDB successfully reduced the pain scale in mild head injury Research at RS Bhayangkara Manado also supported these findings by noting a rapid reduction in pain for head injury patients in the emergency department. 10 These similar results suggest that SDB could be a feasible intervention to implement in various healthcare facilities, whether in the emergency room, inpatient setting, or in the context of post-operative care. 11,12 Mechanisms of Pain Reduction Physiologically, the SDB technique works through a mechanism that involves regulation of the autonomic nervous system. 1 The technique affects the parasympathetic nervous system, which works to calm the body and lower the stress response through the reduction of sympathetic nervous system activity. 4 In this regard. SDB helps to lower heart rate, blood pressure and improve blood oxygenation. 6 All these factors contribute to a decrease in pain perception as the body is in a deeper state of relaxation. 3 Past research has also shown that deep breathing techniques can affect pain receptors and neurotransmitters involved in pain processing, such as endorphins and serotonin. By performing SDB, patients can achieve a state of muscular relaxation and mental calmness, which accelerates the release of these hormones, reducing tension and stress that often worsen pain. Research Limitations Although the results from the four journals showed significant effectiveness, there are some limitations that need to be considered: Sample Size: Some studies had small sample sizes, which could affect the generalizability of the results. Studies with larger sample sizes and more diverse populations would be more convincing to support the wider effectiveness of SDB. Research Design: Two out of four studies used a quasi-experimental design, which while providing important data, is more prone to bias compared to a Randomized Controlled Trial (RCT) design. The lack of control groups in some studies could also affect the validity of the results. Uncontrolled Variables: Some studies may not comprehensively control for other variables that could affect the results, such as the use of additional analgesic medications, patient anxiety levels, or other factors related to demographic background . ge, gender, medical histor. Duration of Intervention: In some studies, the duration of the SDB intervention was relatively Impact of Slow Deep Breathing on Pain in Head Injury Patients: a Review Systematics short . only once or for a few day. 8 There is a need for more large-scale scientific development to assess the sustained benefits of SDB techniques in managing chronic pain in head injury patients. Pain Measurement Tools: Studies used various pain measurement tools such as the Numeric Rating Scale (NRS) and Visual Analog Scale (VAS). While both tools are valid and reliable, differences in the use of measurement tools may affect the consistency of results between studies. Clinical Implications This discovery has several important clinical Wide Application in Various Healthcare Facilities: The SDB technique can be applied in various clinical settings, both in the management of acute pain in the emergency room and in postoperative pain management. This gives room for healthcare professionals to use this technique as an easy-to-perform, safe and effective adjunctive intervention without significant side effects. Reduced Dependence on Analgesics: With a proven significant reduction in pain intensity. SDB can be used as a way to reduce the use of analgesic medications, which often have side effects and risk of dependence. In the context of head injury treatment, especially in patients who may already be receiving various other medications, this is a significant advantage. Flexibility and Cost Effective: SDB is a simple technique, can be learned by patients quickly, and does not require expensive medical equipment. This makes it a cost-effective solution, especially in areas with limited healthcare resources. Recommendations for Future Research Based on the results and limitations found in this study, there are several recommendations for future research: Studies with RCT Design: Further research with a Randomized Controlled Trials (RCT) design involving control and experimental groups may provide stronger and more reliable results. Larger Sample Size: Future studies should use larger sample sizes to increase statistical power and ensure that the study results can be generalized to a wider population. Long-term Studies: Studies that look at the broader effects of SDB use are needed. in patients with chronic pain from head injuries. This is to evaluate whether the reported positive effects can be sustained over a longer period of time. Combination with other therapies: Given that SDB is a non-invasive and easy-to-implement technique, further research could also explore its effectiveness when combined with other non-pharmacological pain therapies, such as progressive muscle relaxation or music therapy. Conclusion The results of the four studies in this review support the hypothesis that SDB is a useful intervention of managing pain in head injury Although there are some limitations in design and sample size, these results still provide strong support that SDB can be used as a complementary non-pharmacological therapy in pain management. Practitioner Recommendations SDB can be implemented in various clinical settings, especially in the context of mild to moderate head injuries. Nurses and other healthcare personnel need to be trained to effectively apply this technique in patients who require non-pharmacological pain management.
