Post-operative pain in children: a review of the literature

Summary

• ? Post-operative pain has been increasingly reported over the last 40 years.
• ? Literature reporting pain in children is increasing.
• ? Although methods of assessing pain in children have been developed over the last 15 years, difficulties still exist.
• ? The long-standing problems of managing pain persist because practice is often based on misconceptions rather than research.
• ? This failure to base practice on research is caused, in part, by the fact that neither medical nor nurse training recognizes pain as a specific subject area in its own right.
• ? Until training changes and practice improves, post-operative pain in children is likely to remain poorly recognized and undertreated.

     

Post-operative pain management: a literature review

• ? The appropriateness of any set of criteria generated to measure the quality of a particular intervention is dependent upon a thorough, up-to-date assessment of the current state-of-the-art. Few areas in nursing have received as much research attention as that of pain control, particularly post-operative pain control.
• ? The following review of the literature ^{* *}The literature review was undertaken as part of a 3–year Department of Health-funded study called the ODySSSy Project where a nursing quality-assurance system was being evaluated in relation to its effect on nursing actions and patient outcomes on the quality of post-operative pain management in 10 acute surgical wards.
  on this subject complements earlier reviews undertaken by Seers (1988) by organizing the information according to four distinct categories, namely environmental issues, nursing actions, patient outcomes and a review of a number of pain measures. This particular format was selected in order to help in the development of structure, process and outcome criteria on the topic of post-operative pain management.
• ? The section on measurement is to inform practitioners about pain-assessment charts and provide ideas about auditing this area.

     

Anticipating and experiencing post-operative pain: the patients' perspective

• ? This study uses a qualitative approach to explore patients' expectations and experiences of pain, factors contributing to the effective/ineffective management of their pain and strategies patients reported as helpful when experiencing pain. Ten patients on a mixed surgical ward at a District General Hospital in the south of England participated in the study.
• ? Pain scores, using a visual analogue scale, were obtained for ‘expected’ pain pre-operatively and ‘worst pain experienced’. A taped in-depth interview exploring patients' experience of pain after surgery took place on the fifth post-operative day.
• ? Details of analgesia were also collected for the 5 days following surgery.
• ? Patients expected pain after surgery but the intensity of the pain they experienced was often significantly greater than anticipated.
• ? Lack of information, inadequate pain assessment and ineffective pain control contributed to this finding.
• ? It is suggested that new pain technology, such as epidural and patient-controlled analgesia, may not change the prevalence and incidence of pain unless the systems these technologies are placed within also change.

     

Postoperative pain in older people: a review of the literature

Aims and objectives. The literature review was conducted to explore those factors which complicate pain management in older people to inform future research, education and nursing practice in this area. Background. Acute pain management in hospitalized older people is complex because of the physiological changes of ageing, pharmacological factors and under‐representation of this patient group in reported research about assessing acute pain. Methods. A review of the literature was undertaken using electronic databases and specified search terms, some hand searching was also used and included the grey literature, textbooks and conference proceedings. A computerized literature search was carried out using CINAHL, Bandolier, Cochrane, Medline, the British Nursing Index and the International Association for the Study of Pain website for the period 1992–2004. The search terms were acute pain, older people, elder care, pain assessment and acute pain services. Thirty‐seven research‐based reviews and published studies and 17 policy documents were included. Conclusions. Managing acute pain well in older adults involves understanding the influence of a series of integrated factors: attitudes and beliefs, physiological ageing processes, pharmacological factors and the social construction of the older person in healthcare contexts. Relevance to clinical practice. This review offers new insight into those factors which, taken together, add complexity to managing acute pain in older people well. Moreover, nurses are the professional group mainly responsible for assessing pain, administering and now prescribing analgesia and evaluating the quality of pain relief in older people. On this basis, they are also the group most likely to effect improved patient outcomes.     

Postoperative pain management: study of patients' level of pain and satisfaction with health care providers' responsiveness to their reports of pain

The present prospective survey was conducted in a 1200-bed hospital to examine postoperative patients' current pain intensity, most intense pain experienced, satisfaction with postoperative pain management, and differences regarding pain and satisfaction levels. All adult patients admitted to a hospital in Hong Kong for surgery, except those receiving local anesthesia, were eligible to enter this study. The patient outcome questionnaire developed by the American Pain Society was used to solicit data about patients' pain and satisfaction with pain relief. The subjects were 294 postoperative patients. Approximately 85% complained about varying degrees of pain during the 24 h prior to the assessment of their pain. When interviewed, most patients complained of mild to moderate pain (median = 2 on a 10-point scale), while the median for 'worst pain intensity' was 5. Approximately 80% of the subjects indicated that both the nurses and physicians reminded them to report pain when it occurred. Only 143 (48.6%) agreed that the nurses and physicians sufficiently emphasized the importance of pain relief. Those who received acute pain services, provided by anesthetists, reported lower levels of current pain intensity. Over 65% of the subjects were satisfied with all levels of health care providers, regarding their postoperative pain management.     

Sensory deprivation and chronic pain: A review of the literature

Aims and objectives: The aim of this paper is to explore the literature into the use of 'Snoezelen' (Sensory Stimulation) for the management of chronic pain. Within the literature there are a number of research studies which have investigated the concept of sensory deprivation and these are considered. The studies indicate the potential of sensory input as a field of research in particular relation to the care of patients within hospital settings where they are removed from their 'normal' level of sensory input and could subsequently experience sensory deprivation. The relationship between sensory restriction and chronic pain is emphasized. This links with investigations of sensory stimulation (Snoezelen) as a potential strategy for the management of chronic pain.

Conclusions: In conclusion, it is suggested that sensory deprivation cannot exist and the term 'sensory restriction' would be more appropriate. It is proposed that there is a need to develop a tool to assist carers in identifying the existence of sensory restriction in their specific client groups to provide a basis for intervention.     

Atypical odontalgia: a review of the literature

OBJECTIVE: To review previous reports of cases of atypical odontalgia to examine its epidemiological and clinical characteristics and to explore the etiology and pathophysiology of the disease. BACKGROUND: Atypical odontalgia is one of many painful conditions that affect the oral cavity and is often overlooked in the differential diagnosis. METHODS: A search of the literature was performed for all cases of atypical odontalgia reported from 1966 to the present. RESULTS: The typical clinical presentation of atypical odontalgia that has been reported involves pain in a tooth in the absence of any sign of pathology; the pain may spread to areas of the face, neck, and shoulder. The existing literature suggests that this condition occurs in 3% to 6% of the patients who undergo endodontic treatment, with high female preponderance and a concentration of cases in the fourth decade of life. Deafferentation seems to be the most likely mechanism to initiate the pain, but psychological factors, alteration of neural mechanisms, and even an idiopathic mechanism have been implicated. Not all reported cases were preceded by trauma to the teeth or gums. The treatment of choice is a tricyclic antidepressant, alone or in combination with a phenothiazine. The outcome is usually fair, with many patients obtaining complete relief from pain. Especially in the absence of overt pathology, particular attention should be paid to avoiding any unnecessary and potentially dangerous dental intervention on the teeth. CONCLUSION: Atypical odontalgia is surprisingly common, of uncertain origin, and potentially treatable.     

Asthma treatment needs: a comparison of patients' and health care professionals' perceptions

BACKGROUND: Patients' perceptions of asthma tend to differ from those of clinicians, who primarily focus on asthma control. Patients' treatment needs and preferences may not be adequately addressed. OBJECTIVE: The aims of this study were as follows: to provide data on unmet treatment needs and to investigate the main finding of a qualitative study using a questionnaire study. METHODS: To assess treatment needs in patients with asthma, focus groups were conducted with patients/parents and clinicians. Based on these results, quantitative surveys of adult patients and parents were performed in the United Kingdom, Germany, and Spain. RESULTS: The UK focus group comprised 11 patients and 8 parents; in Germany, there were 10 patients and 11 parents; in Spain, there were 5 patients and 8 parents. The focus groups showed some differences between clinicians' and patients'/parents' perceptions of treatment. For patients, side effects meant long-term effects (ie, 10-20 years); for clinicians, it meant occasional local problems. The quantitative study comprised 454 participants: 310 adult patients (mean [SD] age, 37.13 [13.12] years) and 142 parents (children's mean [SD] age, 13.98 [1.37] years), plus 2 nonspecified. Some patients reported good asthma control and simultaneously reported frequent exacerbations. Most patients and parents expressed a preference for a simpler regimen using fewer drugs, and most had concerns about their treatment. Although some patients concurred with treatment guidelines, 62.2% tended to rely on reliever medication (ie, bronchodilators). Additionally, 6.9% described their asthma as very well-controlled but reported experiencing asthma symptoms > or =3 days per week. Finally, 1.9% of patients and 2.1% of parents reporting very well-controlled asthma also reported visiting the emergency department or calling a physician for a home visit in the previous 3 months. CONCLUSIONS: Asthma patients and parents of asthmatic children had unmet treatment needs and may interpret medical terminology differently than clinicians.     

Pain: a review of three commonly used pain rating scales

Aims and objectives. This review aims to explore the research available relating to three commonly used pain rating scales, the Visual Analogue Scale, the Verbal Rating Scale and the Numerical Rating Scale. The review provides information needed to understand the main properties of the scales. Background. Data generated from pain‐rating scales can be easily misunderstood. This review can help clinicians to understand the main features of these tools and thus use them effectively. Method. A MedLine review via PubMed was carried out with no restriction of age of papers retrieved. Papers were examined for methodological soundness before being included. The search terms initially included pain rating scales, pain measurement, Visual Analogue Scale, VAS, Verbal Rating Scale, VRS, Numerical/numeric Rating Scale, NRS. The reference lists of retrieved articles were used to generate more papers and search terms. Only English Language papers were examined. Conclusions. All three pain‐rating scales are valid, reliable and appropriate for use in clinical practice, although the Visual Analogue Scale has more practical difficulties than the Verbal Rating Scale or the Numerical Rating Scale. For general purposes the Numerical Rating Scale has good sensitivity and generates data that can be statistically analysed for audit purposes. Patients who seek a sensitive pain‐rating scale would probably choose this one. For simplicity patients prefer the Verbal Rating Scale, but it lacks sensitivity and the data it produces can be misunderstood. Relevance to clinical practice. In order to use pain‐rating scales well clinicians need to appreciate the potential for error within the tools, and the potential they have to provide the required information. Interpretation of the data from a pain‐rating scale is not as straightforward as it might first appear.     

A pain monitoring program for nurses: effects on communication, assessment and documentation of patients' pain

Nurses need to be informed about the patient's pain to be able to take appropriate measures to alleviate pain. However, communication, assessment, and documentation of pain by nurses is often a problem for hospitalized patients. In this study we aimed to overcome the main barriers by developing, implementing, and evaluating a Pain Monitoring Program (PMP) for nurses. The PMP consists of two components: educating nurses about pain, pain assessment and pain management; and implementing daily pain assessment by means of a numeric rating scale. We describe the effects of the PMP on communication about pain between nurses and patients and between physicians and patients, agreement between patients' pain intensity and nurses estimations of patients' pain intensity, and documentation about pain in the nursing records. Factors that might influence communication, assessment, and documentation are also discussed. The effects of the PMP were measured in a quasi-experimental design with a nonequivalent control group. In total, 703 patients participated: 358 patients in the control group and 345 in the intervention group. Results of the control group showed that communication about pain between nurses and patients, agreement between patients' and nurses pain ratings, and documentation about pain in nursing records, remain inadequate. Patients' pain intensity and age were related to communication, assessment, and documentation. Communication and documentation is better in patients with moderate to severe pain than in patients with mild pain, and assessment is better in patients with mild pain. Older patients communicate less with nurses and physicians about pain, and nurses document less about pain in nursing records for older patients compared with younger patients. The PMP proved to be effective in improving nurses' assessment of patients' pain and documentation about pain in nursing records. Patients' pain intensity and care setting were related to the efficacy of the PMP. Communication about pain between patients and nurses, and between patients and physicians did not improve as a result of the PMP. Based on this study it can be concluded that in using a simple method such as the numeric rating scale, together with an education program, attention is focused in a systematic way on patients' pain complaints and creates a common language between patients and nurses. Because the PMP proved effective in a heterogenous population in multiple care settings, it is recommended to implement the PMP in nursing practice.     

The neuropathic component in persistent postsurgical pain: A systematic literature review

Persistent postsurgical pain (PPSP) is a frequent and often disabling complication of many surgical procedures. Nerve injury–induced neuropathic pain (NeuP) has repeatedly been proposed as a major cause of PPSP. However, there is a lack of uniformity in NeuP assessment across studies, and the prevalence of NeuP may differ after various surgeries. We performed a systematic search of the PubMed, CENTRAL, and Embase databases and assessed 281 studies that investigated PPSP after 11 types of surgery. The prevalence of PPSP in each surgical group was examined. The prevalence of NeuP was determined by applying the recently published NeuP probability grading system. The prevalence of probable or definite NeuP was high in patients with persistent pain after thoracic and breast surgeries—66% and 68%, respectively. In patients with PPSP after groin hernia repair, the prevalence of NeuP was 31%, and after total hip or knee arthroplasty it was 6%. The results suggest that the prevalence of NeuP among PPSP cases differs in various types of surgery, probably depending on the likelihood of surgical iatrogenic nerve injury. Because of large methodological variability across studies, a more uniform approach is desirable in future studies for evaluating persistent postsurgical NeuP.     

The emotional pain and distress of borderline personality disorder: a review of the literature

This paper presents a synthesis of content and assessment of the methodological rigour of published literature related to concepts of emotional pain and distress in women with a diagnosis of borderline personality disorder (BPD). In the past two decades, there has been an increase in research about the prevalence of BPD, interventions, and relative effectiveness of various forms of treatment. However, there are few studies regarding emotional pain and distress in women with BPD. Emotional pain has been reported as an adaptive response to repetitive traumatic experiences in childhood. Searches of the EBSCO host, OVID MEDLINE, CINAHL, and PsycINFO databases were carried out using the following search words: borderline personality disorder, emotional pain, distress, self, suffering, women, for the period 1996-2006. Fifteen papers were assessed for methodological rigour, followed by the analysis of the concepts of emotional pain and distress. Three themes emerged from the literature, the emotionally abused and neglected child; struggling with emotions leading to self-injury; and social problems related to difficulties regulating emotions. A high prevalence of reported childhood abuse was revealed. Emotional pain was described as intense for women suffering from BPD. A further synthesis of research findings is recommended to provide information on the effectiveness of interventions.     

A literature review exploring how healthcare professionals contribute to the assessment and control of postoperative pain in older people

Little research has examined the care older people receive in the acute surgical setting. Although pain assessment and management are judged to be a priority in nursing, often pain, in older people, is undermanaged for a variety of reasons. Factors such as stoicism, communication and ageism can shape both the patients’ and nurses’ attitude towards the perception of pain which subsequently affects pain management. Through a review of the literature, this paper aims to: (i) identify how healthcare professionals contribute to the assessment and control of postoperative pain in older people and (ii) explore potential barriers to achieving more advantageous pain control in this group. It is suggested that to improve pain management there is a need to individualize pain assessment for older people and to assist clinicians with enhancing their education and decision‐making abilities in this field. This may best be achieved by supporting a programme of change to develop the skills of staff and encouraging learning through reflective practice. There is however a need for further research in this area.     

Validity of 24-h recall ratings of pain severity: biasing effects of "Peak" and "End" pain

Despite the frequent use of pain recall ratings in clinical research, there remains doubt about the ability of individuals to accurately recall their pain. In particular, previous research indicates the possibility that the most pain experienced during a recall period and the most recent pain experienced (known as peak and end effects, respectively) might bias recall ratings. The current study used data from a published clinical trial to determine the relative validity of a 24-h recall rating of average post-operative pain and the nature and extent of any biasing influence of peak and end effects on nine separate 24-h recall ratings. The results supported a statistically significant but small biasing influence of both peak and end pain. Also, the influence of peak pain was stronger than that of end pain. However, the biasing impact of both peak and end pain together was very small, suggesting that 24-h recall ratings are adequately valid indicants of average pain for patients participating in post-surgery clinical pain trials.     

Addiction to opioids in chronic pain patients: a literature review.

Opioids have proven very useful for treatment of acute pain and cancer pain, and in the developed countries opioids are increasingly used for treatment of chronic non-malignant pain patients as well. This literature review aims at giving an overview of definitions, mechanisms, diagnostic criteria, incidence and prevalence of addiction in opioid treated pain patients, screening tools for assessing opioid addiction in chronic pain patients and recommendations regarding addiction problems in national and international guidelines for opioid treatment in cancer patients and chronic non-malignant pain patients. The review indicates that the prevalence of addiction varied from 0% up to 50% in chronic non-malignant pain patients, and from 0% to 7.7% in cancer patients depending of the subpopulation studied and the criteria used. The risk of addiction has to be considered when initiating long-term opioid treatment as addiction may result in poor pain control. Several screening tools were identified, but only a few were thoroughly validated with respect to validity and reliability. Most of the identified guidelines mention addiction as a potential problem. The guidelines in cancer pain management are concerned with the fact that pain may be under treated because of fear of addiction, and the guidelines in management of non-malignant pain patients include warnings of addiction. According to the literature, it seems appropriate and necessary to be aware of the problems associated with addiction during long-term opioid treatment, and specialised treatment facilities for pain management or addiction medicine should be consulted in these cases.     

The use of benzodiazepines in the treatment of chest pain: a review of the literature

Benzodiazepines, although not listed in the American Heart Association's guidelines for the treatment of chest pain, are often used to provide symptomatic relief to patients who experience chest pain. To investigate the utility of benzodiazepines in the treatment of chest pain, the pharmacologic actions and cardiovascular effects of benzodiazepines were reviewed. In addition, a literature search regarding the use of benzodiazepines to treat patients with chest pain was conducted. The results indicated that benzodiazepines reduce anxiety, pain, and cardiovascular activation. Benzodiazepines amplify gamma-aminobutyric acid (GABA) throughout the central nervous system, and act more peripherally to reduce catecholamines. In addition, preliminary evidence indicates that benzodiazepines may cause coronary vasodilatation, prevent dysrhythmias, and block platelet aggregation, though further study is needed. Both non-cardiac chest pain (associated with musculoskeletal, esophageal, neurologic, and psychiatric conditions) and cardiac chest pain (associated with acute and chronic myocardial ischemia) seem to be effectively treated with benzodiazepines. Benzodiazepines are safe and well tolerated when administered alone or in combination with other medications. Moreover, the risk of dependence is minimal when benzodiazepines are prescribed on a short-term basis. Further study of benzodiazepines in the treatment of acute chest pain is needed to confirm these favorable actions and better define their use in the acute medical setting.
