Brazilian tracheotomy speech valve: diaphragm pressure standardization.

UNLABELLED: Tracheotomy is performed in cases of upper airway obstruction or chronic pulmonary disorders. The Tracheotomy Speech Valves (TSV) improve communication and airway hygiene and humidification of tracheotomized patients. AIM: To show the low cost Brazilian TSV and its use in speech rehabilitation of tracheotomized patients, to evaluate diaphragm opening resistance and comfort to the patient. STUDY DESIGN: Experimental, contemporary cohort. MATERIALS AND METHODS: The TSV was used in 32 patients. The valve has a diaphragm within a stainless steel body with plastic fittings. We studied the level of respiratory comfort according to the degree of valve diaphragm resistance, 40, 50 and 60 shores. RESULTS: All the patients used the TSV coupled to the cannula in a regular basis, 26 of them did it for more than 12 hours daily and from these, 14 used it for 24h daily. The diaphragm pressure obtained was that of 40 shores for 13 patients and 50 shores for 19 patients. 60 shores was never used. CONCLUSION: the metal TSV helps with speech without the need for closing the cannula with one's finger, and breathing was comfortable. We achieved standard diaphragm resistance. Currently all the patients from this study use this TSV with speech and 43.75% use it full time.

Válvula fonatória brasileira para traqueotomia: padronização de pressão de diafragma / Brazilian tracheotomy speech valve: diaphragm pressure standardization

A traqueotomia está indicada em condições com obstrução respiratória alta ou doença pulmonar obstrutiva crônica. As Válvulas Fonatórias (VF) melhoram a comunicação, higienização e umidificação das vias aéreas dos pacientes traqueotomizados. OBJETIVO: Demonstrar a VF nacional, de menor custo, e sua utilização na reabilitação fonatória desses pacientes, avaliar resistência de abertura pelo diafragma, o que confere melhor conforto ao paciente. Forma de Estudo: Experimental, coorte contemporâneo. MATERIAL E MÉTODO: A VF foi utilizada em 32 pacientes. A válvula tem diafragma dentro de um corpo em aço inox com encaixes de plástico. Estudou-se grau de conforto respiratório de acordo com a resistência do diafragma da válvula, 40, 50 e 60 shores. RESULTADOS: Obteve-se uso regular da VF acoplada à cânula por todos os pacientes, 26 o fizeram por mais de 12h diárias e destes 14 por 24h diárias. A pressão do diafragma obtida foi de 40 shores para 13 pacientes e 50 shores para 19 pacientes, sem utilização de 60 shores. CONCLUSÃO: A VF metálica permite fonação, sem a oclusão digital da cânula, e respiração sob conforto. Obteve-se resistência padronizada do diafragma. Atualmente todos os pacientes do estudo utilizam estas VF com fonação e 43,75% período integral.

Tracheostoma humidifier: influence on secretion and voice of patients with total laryngectomy.

BACKGROUND: total laryngectomy has several consequences such as loss of the laryngeal voice and alterations in the respiratory system. AIM: to evaluate the influence of a tracheostoma humidifier (heat moisture exchanger - HME) on the control of lung secretion and esophageal and tracheoesophageal vocal quality in patients with total laryngectomy. METHOD: nine male individuals, aged between 46 to 67 years, submitted to total laryngectomy. The patients answered a protocol containing subjective questions related to lung secretion in three different moments: T1 (pre-use assessment of the HME), T2 (pre-use assessment of the HME six weeks after the first assessment) and T3 (assessment six weeks after the use of the HME). Voice samples were recorded during these 3 different assessments and were evaluated by three speech-language pathologists, in a blind study format, according to a perceptual auditory vocal analysis protocol. The non-parametric test of Wilcoxon was used to compare results of both protocols. RESULTS: no significant differences were observed for tracheoesophageal and esophageal vocal quality in the three different moments of assessment: T1 (pre-use assessment of the HME), T2 (pre-use assessment of the HME six weeks after the first assessment) and T3 (assessment six weeks after the use of the HME). On the other hand, there were significant differences, after the period of the HME use, regarding occurrence of cough and forced expectoration during the day time. CONCLUSION: The use of the HME during the period of six weeks reduced cough and expectoration of patients with total laryngectomy. However, the use of the humidifier did not have any influence on the tracheoesophageal and esophageal vocal quality of these patients.

Umidificador de traqueostoma: influência na secreção e voz de laringectomizados / Tracheostoma humidifier: influence on secretion and voice of patients with total laryngectomy

TEMA: a laringectomia total acarreta sequelas como a perda da voz laríngea e alteração no sistema respiratório. OBJETIVOS: avaliar a influência do uso do umidificador de traqueostoma (heat moisture exchanger - HME) no controle da secreção pulmonar e na qualidade vocal esofágica e traqueoesofágica de pacientes submetidos à laringectomia total. MÉTODO: nove pacientes do sexo masculino, com idades entre 46 a 67 anos, submetidos à laringectomia total. Os pacientes responderam a um protocolo sobre questões subjetivas relacionadas à secreção pulmonar em três momentos, sendo T1 (avaliação pré-uso do HME), T2 (avaliação pré-uso do HME após seis semanas da primeira avaliação) e T3 (avaliação após seis semanas do uso do HME). Conjuntamente foram feitas gravações das vozes dos pacientes nos mesmos três momentos citados acima. As vozes foram avaliadas por três fonoaudiólogas, em estudo cego, de acordo com um protocolo de avaliação perceptivo-auditiva da voz. Para comparar os resultados obtidos em ambos os protocolos aplicados foram utilizados teste não-paramétrico e Wilcoxon. RESULTADOS: não foi observada nenhuma diferença estatisticamente significativa dos parâmetros de qualidade vocal esofágica ou traqueoesofágica entre os tempos T1 (avaliação pré-uso do HME) e T2 (avaliação pré-uso do HME pós seis semanas) e T3 (avaliação após seis semanas do uso do HME). Verificaram-se diferenças estatisticamente significativas para as variáveis de quantidade de tosse e expectoração forçada, durante o dia, após o período de uso do HME. CONCLUSÃO: O uso do HME durante seis semanas diminuiu a tosse e a expectoração em pacientes laringectomizados totais, porém não apresentou influência na qualidade vocal esofágica ou traqueoesofágica.

Primary versus secondary tracheoesophageal puncture for speech rehabilitation in total laryngectomy: long-term results with indwelling voice prosthesis.

OBJECTIVE: To evaluate the long-term use of indwelling Blom-Singer voice prosthesis (VP) for vocal rehabilitation of patients submitted to total laryngectomy (TL). The influence of the timing (primary or secondary) of tracheoesophageal puncture (TEP), use of radiotherapy (xRT), patient age, and length of follow-up were studied to evaluate the success rate of VP use. STUDY DESIGN AND SETTING: Prospective clinical study in a tertiary referral center. Seventy-one patients were submitted to TL and rehabilitated with indwelling VP. All patients were evaluated for vocal functional issues by an otolaryngologist and a speech pathologist at 1 month, then at every 3 months up to 1 year, and then at every 6 months after 1 year of follow-up. The relative data on time of placement of VP, time of VP use, xRT, age, length of follow-up, and life span of each VP were recorded during the follow-up. RESULTS: Eighty-seven percent of the patients underwent primary and 13%, secondary TEP. The follow-up varied from 12 to 87 months, with an average of 38 months for primary and 51 months for secondary TEP. Fifty-nine percent of the patients were submitted to xRT. The general rate of success was 94%, with 97% for primary and 78% (P = 0.07) for secondary TEP; after 2 years, the success rate was 96% for primary and 75% for secondary (P = 0.07) TEP. The use of xRT and patient age had no influence on the success of VP use for primary and secondary TEP, independently of the length of follow-up. CONCLUSIONS: The success rate of voice rehabilitation with VP was 94%. In primary TEP, the success rate was 97%, whereas in secondary TEP it was 78%; 2 years later, it was 96% and 75%, respectively. A tendency for a higher success rate in voice rehabilitation after TL was observed in primary TEP. The use of xRT and age of patient had no influence on the success rate.
