Recovery position significantly associated with a reduced admission rate of children with loss of consciousness.

BACKGROUND: Loss of consciousness (LOC) is often seen in children. The response of caregivers to a child with LOC has been poorly investigated. Potential caregivers (parents, teachers) seem to have a poor knowledge of the recovery position (RP)-that is, the position into which an unconscious child should be placed in order to protect the airway. OBJECTIVES: To report the management and diagnoses of LOC in childhood, and to evaluate variables associated with an increased hospital admission rate. METHODS: We conducted a prospective cohort study of consecutive children aged between 0 and 18 years diagnosed with LOC at 11 paediatric emergency departments (PEDs) of 6 European countries. The enrolment period was 3 months. Data were obtained from parental interviews, PED reports and clinical examination. RESULTS: 553 children were enrolled. The most frequent final diagnoses causing LOC were seizures (n=278, 50.3%), and vasovagal syncope (n=124, 22.4%). Caregivers put the child in the RP in 145 cases (26.2%). The RP was independently associated with a significant decrease in the admission rate (aOR=0.28; 95% CI 0.17 to 0.48; p<0.0001). CONCLUSIONS: Our study demonstrates for the first time that the RP may reduce the admission rate of infants with LOC. Caregivers often perform inadequate manoeuvres when a child becomes unconscious. Campaigns aiming at increasing knowledge of the RP should be promoted.

Lung function, diagnosis, and treatment of sleep-disordered breathing in children with achondroplasia.

Children with achondroplasia are at risk of sleep-disordered breathing. The aim of the study was to evaluate lung function and sleep-disordered breathing in children with achondroplasia. An interview, clinical examination, lung function tests with blood gases, and a polygraphic sleep study were obtained as part of routine annual evaluation in consecutive children with achondroplasia. We included 30 children (median age 3.0 years, range: 0.4-17.1) over a period of 21 months. Habitual snoring and witnessed apneas were observed in 77% and 33% of the patients, respectively. Prior to the sleep study, 10/29 (34%) patients had undergone upper airway surgery and 5/29 (17%) craniocervical decompression operation. Arterial blood gases were abnormal in two (7%) patients. Sleep findings were abnormal in 28/30 (93%) patients. Eleven (37%) patients had an apnea index≥1 event/hr and 26 (87%) had an apnea-hypopnea index≥5 events/hr. The ≥3% desaturation index was >5/hr in 22 (73%) patients. Sixteen (53%) patients had a minimal pulse oximetry<90% but only two (7%) patients had a maximal transcutaneous carbon dioxide pressure>50 mmHg during sleep. As a consequence, the following therapeutic interventions were performed: upper airway surgery in four patients and noninvasive positive pressure ventilation (NPPV) in five other patients, resulting in an improvement in sleep studies in all nine patients. Systematic sleep studies are recommended in children with achondroplasia because of the high prevalence of sleep-disordered breathing. Upper airway surgery and NPPV are effective treatments of sleep-disordered breathing.
