Introduction: The obstructive sleep apnea-hypopnea syndrome (OSAHS) is usually established using polysomnography (PSG). Most patients diagnosed with this condition receive treatment with continuous positive airway pressure (CPAP). The conventional approach requires performing a full-night PSG and CPAP titration over a two-night stay in a sleep laboratory, which is costly and may present scheduling difficulties. However, the combined use of polysomnography and CPAP titration in a single night, procedure known as split-night polysomnography (SNPSG), is less-expensive and is a time saving strategy for diagnosis and treatment.
Objectives: To characterize the SNPSG studies conducted in the sleep laboratory of the Hospital Universitario Santa Fe de Bogotá (HUFSFB) and assess their performance in the diagnosis and treatment of OSAHS.
Materials and methods: Retrospective, observational and longitudinal study performed on a sample of 221 patients.
Results: 208 (94.1%) SNPSG studies were compatible with OSAHS. Most cases (54.7%) had a hypopnea apnea index (AHI) ≥30. Adequate CPAP titration was achieved in 78% of patients who had severe AHI (p=0.00).
Conclusions: OSAHS was diagnosed and an adequate CPAP titration was achieved in most of the SNPSG studies of the analyzed sample.
Introducción. El diagnóstico del síndrome de apnea/hipopnea obstructiva del sueño (SAHOS) se realiza mediante estudio de polisomnografía (PSG) y la mayoría de los pacientes con este diagnóstico recibe tratamiento con presión aérea positiva continua (CPAP). Este abordaje convencional requiere dos estudios de PSG: uno diagnóstico y otro de titulación. El uso combinado de PSG diagnóstica y de titulación en una sola noche, conocido como noche partida (PSGNP), es una alternativa diagnóstica y terapéutica válida que optimiza la utilización de tiempo y recursos.
Objetivo. Caracterizar los estudios de PSGNP realizados en el laboratorio de sueño del Hospital Universitario de la Fundación Santa Fe de Bogotá (HUFSFB) y evaluar su desempeño.
Materiales y métodos. Se realizó un estudio observacional analítico de tipo longitudinal retrospectivo de una muestra de 221 pacientes.
Resultados. Se registraron 208 (94.1%) estudios de PSGNP compatibles con SAHOS, de los cuales la mayoría de los pacientes (54.7%) presentaron un índice de apnea hipopnea (IAH) ≥30. En 78% de los pacientes que presentaban IAH severo se logró una titulación adecuada del CPAP (p=0.00).
Conclusiones. En la mayor parte de los estudios de PSGNP de la muestra analizada se diagnosticó SAHOS y se consiguió una titulación adecuada del CPAP.
