ABSTRACT: An operation is one of the most traumatic event children face and many of the children experience post-surgical pain lasting for weeks or months. A combination of pharmacological and non-pharmacological method of pain control yields the most effective relief for the patient. Nurses have many approaches to treat pain by a variety of non-pharmacological methods such as distraction, relaxation, meditation, massage and auditory stimulation in combination with the traditional methods of analgesics and of which music is one of the important among these. Music has been recommended as an adjuvant to medication given to relief pain. Music therapy provides distraction and disassociation by focusing on the characteristics of the music selection. Music can block certain pain pathways and diminish the amount of perceived pain. A quasi-experimental study was conducted in Dr. Prabhakar  Kore Hospital and MRC, Belagavi among 30 post-operative children between 6-12 years undergoing abdominal surgeries to evaluate the effectiveness of music therapy on post-operative pain intensity and to associate the pretest scores of pain intensity of children with selected socio-demographic variables. The subjects were assigned to experimental and control groups by using convenience sampling with an evaluative approach. In experimental group, music therapy (instrumental music) was administered through head phone for 20 minutes of two sessions, at an interval of one hour between each session. Data was collected by using Oucher numerical pain scale. Data obtained were tabulated and analyzed in terms of objectives of the study using descriptive and inferential statistics. The mean post test pain scores for the experimental group after 1stsession was 44 and that of 2nd session was 39.3 while the mean 1st and 2ndpost test pain scores of the control group was 56.7.The study findings showed that there was statistically significant difference in the post interventional pain scores between experimental and control groups at P<0.05 level of significance but there was no association found between the pre test pain scores with selected socio-demographic variables.

 

KEY WORDS: Music therapy, pain intensity, post-operative children, abdominal surgeries, Oucher numerical pain scale.

 


 

INTRODUCTION:

“Pain is whatever the experiencing person says it is, existing whenever the person says it does.’’

                                                Mccaffery and Pasero

 

Pain is a complex multidimensional experience. For many people, it is a major problem that causes suffering and reduces quality of life. A thorough understanding of the physiologic and psychologic dimensions of pain is important for effective assessment and management of patients with pain.1  An operation is one of the most traumatic event children face, and many of the children experience post-surgical pain lasting for weeks or months.2To manage post-operative pain safely and effectively in children, focus should be given on reorganization of pain in children, minimization of moderate and severe pain safely in all children, to preserve pain where it is predictable, to bring pain rapidly under control and to continue pain control after discharge from the hospital.3

 

A combination of pharmacological and non-pharmacological method of pain control yields the most effective relief for the patient. Nurses have many approaches to treat pain by a variety of non-pharmacological methods such as distraction, relaxation, meditation, massage and auditory stimulation in combination with the traditional methods of analgesics and of which music is one of the important among these.4Music has been recommended as an adjuvant to medication given to relief pain.5 Music therapy can help to relieve pain and reduce stress and anxiety for the patient thereby decreasing sympathetic nervous system output and dampening the overall excitability of the central nervous system. The relaxation response results to improve breathing, lower blood pressure and heart rate, reduce muscle tension, increase attention span, improve memory, mental acuity and social interaction and increase orientation to reality.6

 

Additional advantages of using music therapy in pain relief are that it is not harmful to patients; has minimal risks, and its costs are low, which means that music therapy has great potential to reduce suffering. As a specific nursing intervention, music was found to be advantageous, particularly owing to its lack of adverse reactions and as a non-invasive therapy, it is relatively inexpensive, and ease to administer.7

 

NEED FOR THE STUDY:

“He took his pain and turned it into something beautiful. Into something that people connect to. And that's what good music does. It speaks to you. It changes you.”

-Hannah Harrington, Saving June:

 

When coming into hospital, children and their families are often worried that they may be in pain and are anxious to know what will be done to prevent and relieve any discomfort. Although pain is a predictable part of the postoperative experience; inadequate management of pain is common and can have profound implications. Unrelieved postoperative pain may result in clinical and psychological changes that increase morbidity, mortality, and costs and decrease the quality of life. Despite recognition of the importance of effective control, up to 70% of children still complain of moderate to severe pain post operatively. Pain relief is an important part of child’s care after an operation or procedure and it is our aim to plan for and minimize pain as far as possible. Research has shown that children whose pain is well controlled recover more quickly and have fewer lasting effects.8

 

Music therapy provides distraction and disassociation by focusing on the characteristics of the music selection. The auditory pathway interacts with the endogenous opiate system at several foci within the brain including the hypothalamus and the limbic system. These are known to project to periaqueductal gray (PAG), providing a mechanism to contribute to pain reduction and /or relief through cerebral activity and spinal cord response. The client should be allowed to choose the type of music when music therapy is used to relief pain and music should be given for at least 15mins.9A statistical pooling shows that patients who listened to music had a 70% greater probability of having at least 50% of pain relief than patients who did not listen to music.10

 

So, helping pediatric patients cope with the painful procedures is a critical element in providing comprehensive medical care. Although pharmacologic agents such as analgesics, sedatives are used, they do not address all the elements of a painful experience and can have undesirable side effects. Because of this, there has been a concerted effort to find non-pharmacologic therapies that can be used to reduce reliance on pharmacologic agents. The use of music to help children and adolescents cope with pain has been the subject of considerable research.11

 

Music is a form of communication, and has been described as a universal language, and so it can provide an escape from negative stimuli such as pain and anxiety to something pleasant and encouraging. A patient’s mind can escape into his or her own familiar and soothing world. Music can block certain pain pathways and diminish the amount of perceived pain.12

 

The researcher in her clinical nursing practice observed that nurses are constantly challenged with the management of post-operative pain in children. As nurses are the only person who provide round the clock care of the post-operative children, it is vital for the nurse to find other means for reducing pain in children like music therapy besides routine analgesic so that the children’s comfort and well-being can be improved; on the other hand they are being prevented from the adverse side effects of the routine analgesics. Therefore, this study further inspired to investigate this predicament and generate facts that will equip nurses with the necessary knowledge; to make better evidence- based decisions regarding the use of music therapy for reducing post-operative pain in children.

5. Association between the pre-interventional pain scores with selected socio-demographic variables.

The chi square test result showed that there was no significant association between the pre interventional pain scores with selected socio- demographic variables of the study subjects.

 

CONCLUSION:

The result of the study showed that there was a statistically significant difference in the post interventional pain scores between experimental and control group at 0.05 level of significance. i.e. there was significant reduction in the pain intensity among the post-operative children after the administration of music therapy. So, music therapy was proved to be effective treatment for pain. Therefore, this policy should be promoted as an Institutional policy and implemented as a routine care for all post-operative children following surgery for the effective management of pain

 

NURSING IMPLICATIONS:

The findings of this study have implication for nursing services, nursing education, nursing administration and nursing research.

 

1. Nursing Services:

This study highlights the nurses about the importance of the management of post-operative pain in pediatric patients with abdominal surgeries. Based on the findings of the study results, the nurses can use music therapy as an effective management of post-operative pain in pediatric patients following abdominal surgeries thereby reducing the use of pharmacological interventions in the management of post-operative pain in them. Also, it will improve the skills of pain assessment using Oucher numerical pain scale.

 

2. Nursing Education:

Pain in the pediatric patients is of major concern especially after surgery. The findings of this study will help the nurse educator to know about the post-operative pain following abdominal surgeries and thus guide her in imparting knowledge regarding assessment as well as treatment of pain. This study will also help the nurse educator to motivate the student nurses to include music therapy as an effective method of pain management.

 

3. Nursing Administration:

The findings of the study can be utilized for the development of evidenced based protocols and policies regarding post-operative pain assessment and its care. Also, the nurse administrator can encourage the utilization of the study findings in daily clinical nursing practices and also can plan for in-service education programs to make staff nurses aware of the use of music therapy as an effective treatment for pain in children

 

4. Nursing Research:

The findings of the study contribute to the body of knowledge of nursing research. It provides guidelines for the researcher to carry out other similar studies in different settings and on a different population on a large scale for greater generalization of the results. The evidenced based nursing will gain higher scope in nursing setting.

LIMITATIONS:

1.       The study was delimited to pediatric surgical ward of KLE Dr. Prabhakar Kore Hospital and MRC, Belagavi, Karnataka.

2.       The study included only 30 post-operative children between 6-12 years who had undergone abdominal surgeries

3.       Control of the extraneous variables was not possible in the clinical setting.   

 

RECOMMENDATIONS:

1.       A similar study can be carried out on larger sample for a longer period of time for broader generalization of the result.

2.       A similar study can be conducted in different setting.

3.       A similar study can be done on patients with other surgeries and during nursing procedures.

4.       A similar study can be conducted using randomized sampling technique.

5.       A study can be done to compare the effect of music with a placebo to evaluate the effect on intensity of pain.

6.       A similar study can be conducted on children of other age group using other pain scale assessment tool.

7.       A study can be done on the staff nurses to assess the knowledge and practice regarding pain management of post-operative children
