Pulmonary function pre- and post-total laryngectomy

Abstract

Pulmonary function pre- and post-total laryngectomy was assessed in 16 patients without overt inspiratory stridor preoperatively. It could be shown that total laryngectomy is associated with a significant decrease in vital capacity and in an increase in inspiratory flow-volume values 9 days postoperatively. The inspiratory values tended to increase slightly over the next half year. The measured expiratory flow-volume values were preoperatively already significantly lower than the predicted values, and no significant changes could be observed immediately after the operation nor after 6 months. These alterations have to be taken into account when judging the pulmonary function after total laryngectomy.

A study of the effect of a resistive heat moisture exchanger (trachinaze) on pulmonary function and blood gas tensions in patients who have undergone a laryngectomy: A randomized control trial of 50 patients studied over a 6‐month period

“…All symptom assessment scales have been used in studies by others and ourselves [11][12][13][14][15] and have been validated for this study in pilot studies during development of the filter. It was found that these five simple scales could accurately differentiate symptoms produced by altered physiology, environment, or disease.…”

“…These were FEV 1 , FVC, and PIF. 14,15 Flow volume loops were recorded but after analysis with calculus yielded no more useful information than the three standard measures of lung function. 14 The usual spirometer mouthpiece is useless in patients with an end tracheostomy.…”

Umidificador de traqueostoma: influência na secreção e voz de laringectomizados

“…Prior studies, most of them conducted on the Dutch Cancer Institute by Ackerstaff et al (1)(2)(3)6,9), with objective and subjective tests have shown decrease of breathing problems and therefore the improvement of subject's voice quality. It is important to point out that the improvement of voice quality wasn't evidenced through objective tests.…”

“…As a consequence respiratory problems characterized by the excessive production of secretion, cough, forced expectoration to air-way cleansing , stoma cleansing and reduced lung capacity are common features on this kind of patient. In addition changes on the pulmonary physiology may produce a decrease on the pressure gradient of pulmonary alveolus and trachea (2)(3)(4)(5)(6)(7)(8).…”

Effectiveness of Bronchodilator Therapy on Dyspnoea After Total Laryngectomy

“…1 In laryngectomies, in the first two months after a tracheostomy, an increase occurs in the efficiency of the mucociliary clearance. This is probably due to a reactive bronchial hypersecretion, which protects the respiratory mucosa by direct contact with the airflow, which is no longer filtered and conditioned by nasal mucosa.…”
