A daytime polysomnography, which might be more useful than a night-time recording was proposed in childhood cases. The subjects were 25 children suffering from sleep respiratory disturbances. They were given monosodium trichlorethyl phosphate as a somniferous agent, and underwent a daytime polysomnography. Polysomnographic recordings were also made during the night with no sedation. The polysomnographic parameters, including AT, AHI, lowest SaO2 and mesopharyngeal pressure amplitude (MPA), were computed and daytime and nighttime data were compaired.
Correlations between daytime and nighttime values were evident: AT (r=0.903), AHI (r=0.921), lowest SaO2 (r=0.876) and MPA (r=0.812). Daytime polysomnography, including the measurement of MPA, was thus considered to be useful for the diagnosis of pathological site and severity of sleep respiratory disoders in children.
