RESUMEN
STUDY OBJECTIVES: Drug-induced sleep endoscopy (DISE) using propofol is commonly used to identify the pharyngeal structure involved in collapse among patients with obstructive sleep apnea. DISE has never been compared with zolpidem-induced sleep endoscopy. We hypothesized that propofol at recommended sedation levels does not influence upper airway collapsibility nor the frequency of multilevel pharyngeal collapse as compared with zolpidem-induced sleep. METHODS: Twenty-one patients with obstructive sleep apnea underwent polysomnography and sleep endoscopy during zolpidem-induced sleep and during DISE with propofol. A propofol target-controlled infusion was titrated to achieve a bispectral index between 50 and 70. Airway collapsibility was estimated and compared in both conditions by peak inspiratory flow and the magnitude of negative effort dependence. Respiratory drive was estimated by the difference between end-expiratory and peak-negative inspiratory pharyngeal pressure (driving pressure). Site and configuration of pharyngeal collapse during zolpidem-induced sleep and DISE with propofol were compared. RESULTS: The frequency of multilevel collapse during zolpidem-induced sleep was similar to that observed during DISE with propofol (72% vs 86%, respectively; difference: 14%; 95% confidence interval: -12% to 40%; P = .453). The endoscopic classification of pharyngeal collapse during both conditions were similar. Peak inspiratory flow, respiratory drive (effect size: 0.05 and 0.03, respectively), and negative effort dependence (difference: -6%; 95% confidence interval: -16% to 4%) were also similar in both procedures. CONCLUSIONS: In this pilot study, recommended propofol doses did not significantly increase multilevel pharyngeal collapse or affect upper airway collapsibility and respiratory drive as compared with zolpidem-induced sleep.

OBJECTIVE: To investigate the profile of motivations for smoking among inpatients at a hospital in southern Brazil. METHODS: A survey study involving hospitalized smokers. The Modified Reasons for Smoking Scale (MRFSS) and its domains were analyzed according to gender and dependence degree. RESULTS: The sample consisted of 85 adults (mean age 53 years), low schooling/family income, and well-adjusted in terms of gender (male= 52.9%) and clinical (48%) or surgical (47%) specialty. Most were in Action as the motivational stage (68%), with elevated smoking exposure (median = 39 years/packs) and dependence degree of nicotine (56.4%). The highest domains of the MRFSS were: Smoking Pleasure (4.34 ± 1.2), Relaxation/Tension Reduction (4.24 ± 1.2) and Dependence (3.8±1.4). Significantly, women presented higher scores, in domain Relaxation/Tension Reduction (4.7±0.9). In those with elevated nicotine dependence, higher scores were observed in the Automatism/Habit and Stimulation domains. CONCLUSIONS: Smoking Pleasure and Relaxation/Tension Reduction, especially in women and Automatism, in those more dependents, are factors that should be more highlighted in future strategies for smoking cessation in inpatients.

RESUMO OBJETIVO: Investigar o perfil de motivações para o tabagismo entre pacientes internados em um hospital do sul do Brasil. MÉTODOS: Estudo tipo survey que incluiu pacientes tabagistas hospitalizados. Utilizou-se a Escala de Razões para Fumar Modificada (ERPFM) e seus domínios, analisados em função do sexo e do grau de dependência. RESULTADOS: A amostra foi composta por 85 adultos (média de 53 anos), com baixa escolaridade/renda familiar e equilibrada quanto ao sexo (masculino= 52,9%) e por especialidade clínica (48%) ou cirúrgica (47%). A maioria estava em estágio motivacional Ação (68%), com carga tabágica (mediana= 39 anos/maços) e grau de dependência à nicotina elevados (56,4%). Os domínios de maior escore da ERPFM foram: Prazer de Fumar (4,34 ± 1,2), Relaxamento/Redução da Tensão (4,24 ± 1,2) e Dependência (3,8 ± 1,4). De forma significativa, com maior pontuação, as mulheres apresentaram o domínio Relaxamento/Redução da Tensão (4,7 ± 0,9). Naqueles com maior grau de dependência, observou-se com significância, escores mais elevados nos domínios Automatismo/Hábito e Estimulação. CONCLUSÕES: Prazer de Fumar e Relaxamento/Redução da Tensão, especialmente em mulheres e Automatismo, naqueles mais dependentes, são fatores que devem ser mais valorizados em futuras estratégias de cessação de tabagismo em hospitalizados.
