Sleep-related laryngospasm

Laringospasmo relacionado ao sono

Abstracts

Seven patients (mean age 46.6; range 33-58; 6M.1F) presented with sleep-related choking episodes and were found to have features in common that distinguished them from other known causes of choking episodes during sleep. The characteristic features include: an awakening from sleep with an acute choking sensation, stridor, panic, tachycardia, short duration of episode Gess than 60 seconds), infrequent episodes (typically less than 1 per month), and absence of any known etiology. The disorder most commonly occurs in middle-aged males who are otherwise healthy. In one patient an episode of laryngospasm was polysomnographically documented to occur during stage 3. The clinical features and the polysomnographic findings suggest spasm of the vocal cords of unknown etiology.

Sete pacientes (média de idade = 46,6; variação de 33-58; 6M,1F) apresentavam episódios de sufocamento estritamente relacionados ao período de sono. Esses episódios tinham características que os diferiam de outras causas conhecidas de sufocamento durante o sono. Estas características incluem: despertar com súbita sensação de sufocamento, estridor, pânico, taquicardia. Os episódios eram breves (< 60s), infrequentes (< 1 por mês) e não apresentam qualquer evidência de etiologia conhecida. O distúrbio ocorre em homens saudáveis de meia idade. Em um paciente um episódio foi documentado polissonograficamente durante o estágio 3. Os aspectos clínicos e polissonográficos sugerem espasmo das cordas vocais de etiologia desconhecida.

SUMMARY

Seven patients (mean age 46.6; range 33-58; 6M.1F) presented with sleep-related choking episodes and were found to have features in common that distinguished them from other known causes of choking episodes during sleep. The characteristic features include: an awakening from sleep with an acute choking sensation, stridor, panic, tachycardia, short duration of episode Gess than 60 seconds), infrequent episodes (typically less than 1 per month), and absence of any known etiology. The disorder most commonly occurs in middle-aged males who are otherwise healthy. In one patient an episode of laryngospasm was polysomnographically documented to occur during stage 3. The clinical features and the polysomnographic findings suggest spasm of the vocal cords of unknown etiology.

Key words: laryngospasm, vocal cord spasm, choking, stridor, sleep.

RESUMO

Sete pacientes (média de idade = 46,6; variação de 33-58; 6M,1F) apresentavam episódios de sufocamento estritamente relacionados ao período de sono. Esses episódios tinham características que os diferiam de outras causas conhecidas de sufocamento durante o sono. Estas características incluem: despertar com súbita sensação de sufocamento, estridor, pânico, taquicardia. Os episódios eram breves (< 60s), infrequentes (< 1 por mês) e não apresentam qualquer evidência de etiologia conhecida. O distúrbio ocorre em homens saudáveis de meia idade. Em um paciente um episódio foi documentado polissonograficamente durante o estágio 3. Os aspectos clínicos e polissonográficos sugerem espasmo das cordas vocais de etiologia desconhecida.
