Popis: | Aims of the study Respiratory-related evoked potentials (RREPs) are a method of recording brain activities in response to respiratory stimuli. Although data in childhood are scarce, the absence of the early P1 component of RREPs has been reported in children with a history of life-threatening asthma. This study was focused on the presence, latencies, and amplitudes of the P1, N1, P2, and N2 components of the RREPs in a paediatric series of asthmatic patients. Patients and methods RREPs were recorded in 21 patients with stable asthma, age range 8–17 years, 11 healthy children, age range 6–16 years, and 24 healthy adults, age range 20–28 years. The signals from left (C3–Cz) and right (C4–Cz) central (rolandic) location were recorded separately, using surface electrodes. Evoked responses to two series of 80 consecutive mid-inspiratory occlusions were averaged. Recordings were analysed manually. Results All 4 RREPs components were significantly more often absent in asthmatic children than in healthy children and adults (P1, p = 0.01; N1, p = 0.008; P2, p = 0.008, N2, p = 0.01). The latencies and amplitudes of the four components were similar in patients and healthy subjects. Conclusion RREPs components were less frequently present in children with asthma than in healthy subjects. This finding should promote the recording of RREPs in other acute and chronic respiratory diseases in children in order to search for possible electroclinical correlations. |
