Comparison of oral and intravenous morphine following acute injury in children.

The objective of this research was to examine the speed of onset and effectiveness of pain relief between oral and intravenous morphine in acutely injured children. An observational study of children aged 3 to 13 years with closed forearm fractures was performed in three accident and emergency departments. The study gathered information on age, gender, body weight, time of arrival, dose, route and time of morphine administration. Pain assessment using a Faces Scale was documented on arrival and repeated at 10, 30 and 60 minutes after morphine was given. Forty-seven children were studied. Of these, 25 were given intravenous morphine, 22 were given oral morphine. There was no statistically significant difference in age, body weight or time until morphine was administered. The change in median pain scores was analysed using the Mann-Whitney U test. This showed that there was a statistically significant reduction in pain score in the intravenous group compared with the oral group between arrival and 10 minutes after giving morphine and between arrival and 60 minutes after giving morphine. Intravenous morphine appears to give more rapid onset and more prolonged pain relief than oral morphine for children with acute injuries. We recommend that in accident and emergency departments where staff are experienced in paediatric cannulation, morphine should be given via the intravenous route in acutely injured children. However we do not advocate inexperienced staff attempting multiple venepunctures in a child resulting in increased anxiety.

Magnetic resonance imaging as the primary imaging modality in children presenting with acute non-traumatic hip pain.

The role of magnetic resonance imaging (MRI) in children presenting with acute non-traumatic hip pain was evaluated prospectively. Hip MRI was performed in addition to standard investigations (arthrosonography +/- hip radiographs) in 50 children presenting to the accident and emergency department of a paediatric hospital. MRI was performed on an open 0.23T system and comprised gradient echo T1 weighted coronal, fast spin echo T2 weighted coronal and inversion recovery spin echo (IRSE) axial sequences. Diagnostic quality MRI examinations were obtained in 94% of children. The IRSE sequence was the most reliable at determining underlying disorder (p<0.002). Interobserver agreement on the MRI examinations was very good with unweighted kappa value of 0.89, 95% confidence intervals 0.79, 0.99. Sensitivity of MRI was 0.79 (0.68, 0.90, specificity 1.00 (0.89, 1.00), accuracy 0.81 (0.70, 0.92), PPV 1.00 (0.89, 1), NPV 0.36 (0.25, 0.47). Sensitivity of standard imaging was 0.70 (0.54-0.86), specificity 0.57 (0.41, 0.73), accuracy 0.72 (0.56, 0.88), PPV 0.91 (0.75, 1.00), NPV 0.24 (0.08, 0.40). MRI correctly identified all seven children with serious underlying disorder whereas conventional imaging correctly diagnosed only two. Pelvic musculoskeletal infection was associated with the combination of marked alteration in signal in tissues adjacent to a symptomatic hip and an erythrocyte sedimentation rate of >20 mm 1st h (p<0.0001). In conclusion, MRI is a practical, well accepted and accurate non-invasive imaging technique in children presenting with acute non-traumatic hip pain. Combined with inflammatory markers MRI can be used to determine those children who require aggressive management. Where it is available, MRI is the imaging modality of choice in this condition.

The association between deprivation levels, attendance rate and triage category of children attending a children's accident and emergency department.

OBJECTIVE: To determine the relation between deprivation category, triage score and accident and emergency (A&E) attendance for children under the age of 13. DESIGN: Retrospective study of all children attending an A&E department over one year. SETTING: A paediatric teaching hospital in Edinburgh. SUBJECTS: All children attending the A&E department who had a postcode and a triage score documented on attendance. The postcode was used to determine the deprivation category and the triage scored the severity of illness or injury. MAIN OUTCOME MEASURE: The relation between deprivation category, triage score and frequency of attendance. RESULTS: There is a trend towards increased attendance in all triage categories for deprivation categories 6 and 7. CONCLUSIONS: Attendance at A&E is not only related to severity of injury but also to deprivation category. The reason why people from disadvantaged areas attend more frequently needs further evaluation.

Why do children vomit after minor head injury?

OBJECTIVE: To determine factors associated with vomiting after minor head injury in a paediatric population with the intention of defining the role of vomiting in management decisions. METHODS: A prospective study of all patients presenting with minor head injury to the Royal Hospital for Sick Children, Edinburgh, between 1 May and 30 June 1997. Information regarding basic demographics, features of the head injury and past and family history was noted on a proforma. This included mechanism of injury, site of impact, presence or absence of scalp haematoma, skull fracture or brain injury and intrinsic factors such as age, family history of migraine and a personal history of migraine, its childhood variants and associated conditions. The relation between vomiting and these features was analysed using chi2 and Fisher's exact tests. RESULTS: 563 children aged from birth to 13 years presented with minor head injury. Complete data were obtained on 463 patients. Some 15.8% vomited after minor head injury. Comparing vomiters with non-vomiters the only associated factors that could be identified were a past history of recurrent vomiting or motion sickness (p= 0.0035, p=0.036 respectively). CONCLUSIONS: Vomiting after minor head injury seems to be related to individual intrinsic factors rather than specific features of the head injury and its role in management decisions needs to be explored further.

Presenting features of paediatric meningococcal disease--a five year experience from a paediatric accident and emergency department.

OBJECTIVES: To determine the clinical features, initial management and outcome of meningococcal disease presenting to a paediatric accident and emergency (A&E) department. DESIGN: A retrospective study of all cases of meningococcal disease seen in the department over a five year period. SETTING: A paediatric A&E department which treats approximately 30,000 patients a year. SUBJECTS: All children under the age of 13 years with a discharge diagnosis of meningococcal disease RESULTS: Fifty patients, forty-six with microbiological confirmation of their diagnosis were identified. Sixty six percent of patients were seen first by their general practitioner. However only 28% had received prehospital parenteral antibiotics. Twenty six percent of children had neither meningism nor a classical purpuric rash, 60% showed signs of shock and 66% had an altered conscious level. The case fatality rate was 4%, with 78% making a full recovery. CONCLUSION: Classical features of meningococcal disease are often absent. Assessing simple clinical parameters such as capillary refill, respiratory rate and conscious level adds to the detection of the disease. If meningococcal disease is suspected parental benzylpenicillin should be given and the child transferred to hospital.

Under representation of morbidity from paediatric bicycle accidents by official statistics--a need for data collection in the accident and emergency department.

OBJECTIVES: To determine the accuracy of currently available data on bicycle related injuries in children. SETTING: A paediatric accident and emergency (A&E) department which annually treats approximately 30000 new patients under the age of 13 years. METHODS: Data on all attendances with bicycle related injuries over a four week period were compared with that currently available from police road traffic accident data (Stats 19) and the International Classification of Diseases, 10th revision, hospital discharge coding. RESULTS: Eighty six children attended the A&E department. Only two bicycle related injuries were identified from Stats 19, and 10 from hospital discharge data. CONCLUSION: Currently available official data do not give an accurate representation of the incidence of bicycle related injuries in children. If health promotion measures are to be assessed properly data collection needs to be improved.

The limping child: epidemiology, assessment and outcome.

We investigated the epidemiology, assessment and outcome of acute atraumatic limp in 243 children under the age of 14 years presenting to a paediatric accident and emergency department (AED) over a period of six months. Data were collected at presentation and medical notes were re-examined after 18 to 21 months. The incidence of limp was 1.8 per thousand. The male:female ratio was 1.7:1 and the median age 4.35 years. Limp was mainly right-sided (54%) and painful (80%); 33.7% of the children had localised pain in the hip. A preceding illness was found in 40%. The main diagnosis was 'irritable hip'/transient synovitis (39.5%); Perthes' disease accounted for 2%. Most patients (77%) were managed entirely in the AED. Acute atraumatic limp is a common problem in children presenting to the AED. Most can be safely managed there if guidelines are followed and will have a benign outcome. Further studies are needed to identify the role of preceding illness in the aetiology of acute atraumatic limp.

Sports related injuries in Scottish adolescents aged 11-15.

OBJECTIVES: To measure the age and sex distribution of self reported sports and leisure injuries in a 12 month retrospective recall period among a representative national sample of Scottish adolescents, and to examine the characteristics (gender, age, handedness, and level of sports participation) of sports related injuries in relation to injuries sustained during other activities. DESIGN/SETTING: Self completion questionnaire survey administered in schools during April-June 1994. SUBJECTS: 4710 pupils aged 11, 13, and 15 years drawn from a representative sample of 270 classes with returns from 224 classes (83% completion rate). RESULTS: 42.1% of the sample reported a medically attended injury. These were significantly more frequent among boys but there were no significant age differences in overall frequency of injury. Sport related injuries accounted for 32.2% of all medically attended injuries. As with all injuries, frequency was greater in boys than girls at all ages, and there are differences in the pattern of lesions in sports and nonsports injuries. Lower limb injuries were more frequent than upper limb injury in sports (57.6 v 23.9%), whereas there were no differences in non-sports injuries (31.5 v 31.3%). Age and handedness differences in sports injury rates were also identified. High sports participation was significantly associated with a higher risk of injury in general and sports related injury in particular. CONCLUSION: Age, gender, handedness, and level of sports participation have been shown to be implicated in differential risk of sports related injury. Reducing sports injury among adolescents should be a priority, but research into the injury profiles of different sports is needed before detailed injury prevention strategies can be developed.

Measures of injury severity in childhood: a critical overview.

Many different methods for assessing injury severity have appeared in the literature. This paper discusses the commonly used measures, many of which are subjective and depend on clinical practice or sociological factors. Even if apparently objective measures are used their appropriateness for use in children is questionable. Particular problems occur with scoring or categorising events such as poisoning, choking, and near drowning. Researchers need to reach a consensus on injury severity reporting to ensure comparability between studies and programs for injury prevention.

Prehospital emergency care.

Prehospital care is a diverse and complex entity. Recent studies have begun to emphasize the importance of all aspects of care in the community, leading through to critical analysis of the process of prehospital care provision. This paper examines the various aspects of prehospital care and discusses the various elements which need to be considered to provide effective care prior to patients being attended to at hospital.

Socioeconomic status and adolescent injuries.

Injuries are the major cause of morbidity among children and adolescents in developed countries, but there is a lack of consensus on the relationship between socioeconomic status and risk of injuries. A self-complete questionnaire survey, to gather information on non-fatal injuries and sociodemographic details, was administered in schools during April-June 1994 to a national sample of 4710 Scottish adolescents aged 11, 13 and 15 years. Although there was no evidence of a socioeconomic gradient in the total incidence of medically attended injuries among adolescents, based on the Registrar General's classifications of paternal occupation and a composite measure of family affluence, marked socioeconomic variation in the circumstances in which injuries occurred was observed. There were also socioeconomic differences in the extent and type of risk behaviours reported by adolescents, indicating differential rates of risk exposure. The finding that socioeconomic status affects the kinds of injury events adolescents experience and levels of risk behaviour has implications for the design of injury prevention strategies.
