Use and care of an endotracheal/tracheostomy tube cuff--are intensive care unit staff adequately informed?

BACKGROUND: There is an apparent high incidence of tracheal stenosis in the Bloemfontein area. The aim of this study was to determine intensive care unit (ICU) staff knowledge of the use and care of endotracheal and tracheostomy tube cuffs. METHODS: One hundred and twelve qualified nurses, working in 11 different ICUs, were asked to complete an anonymous questionnaire regarding endotracheal/tracheostomy tube cuffs. RESULTS: The results highlight the following three areas of concern: (i) there was an overall misconception in 38% of the respondents that the function of the cuff was to secure the tube in position in the trachea to prevent self-extubation; (ii) accurate regulation of cuff pressure was not routine practice in any of the ICUs; and (iii) only half of the respondents felt their training regarding cuff care management was sufficient. CONCLUSIONS: ICU staff had misconceptions regarding the function and care of endotracheal/tracheostomy tube cuffs. The concept of a higher cuff pressure for better stabilisation of the tube is probably an important factor that could have caused the increase in tracheal stenosis in the Bloemfontein area. Critical care nursing needs to emphasise the use of current techniques, discourage routine cuff deflation, and encourage collaboration with ICU physicians on standards of care. A protocol that could be used in the ICUs regarding the use and care of an endotracheal/tracheostomy tube cuff is proposed.

Use and care of an endotracheal / tracheostomy tube cuff - are intensive care unit staff adequately informed? : intensive care

Background. There is an apparent high incidence of tracheal stenosis in the Bloemfontein area. The aim of this study was to determine intensive care unit (ICU) staff knowledge of the use and care of endotracheal and tracheostomy tube cuffs. Methods. One hundred and twelve qualified nurses; working in 11 different ICUs; were asked to complete an anonymous questionnaire regarding endotracheal / tracheostomy tube cuffs. Results. The results highlight the following three areas of concern: (i) there was an overall misconception in 38of the respondents that the function of the cuff was to secure the tube in position in the trachea to prevent selfextubation; (ii) accurate regulation of cuff pressure was not routine practice in any of the ICUs; and (iii) only half of the respondents felt their training regarding cuff care management was sufficient.

Incidence and management of acoustic neuromas in South Africa.

OBJECTIVES: To determine the extent to which the various treatment modalities are used in the management of acoustic neuromas treated in South Africa and to estimate the incidence of acoustic neuromas in South Africa. METHODS: A telephonic survey was conducted of all otorhinolaryngologists, neurosurgeons, and radiotherapy centers in South Africa to determine whether they had treated any patients with acoustic neuromas during the calendar year 2000. RESULTS: One hundred and fifteen patients with acoustic neuromas were treated in South Africa during the calendar year 2000, and 8 patients were referred to other countries for treatment. This resulted in an incidence of approximately 0.3 per 100,000 population per year. There was a marked difference in the incidence between the various racial groups: the incidence was at least 1.76 per 100,000 population per year among whites and at least 0.01 per 100,000 population per year among blacks. Of the 115 patients, 78 (68%) were treated surgically and 24 (21%) by stereotactic radiotherapy. Fourteen (12%) patients had newly diagnosed acoustic neuromas that were managed conservatively in the year concerned. The surgical approach used was middle fossa in 8 (7%) patients, retrosigmoid in 61 (53%) patients, and translabyrinthine in 9 (8%) patients. CONCLUSIONS: The majority of acoustic neuromas in South Africa were treated surgically, mainly by a retrosigmoid approach. The incidence of acoustic neuromas in South Africa was approximately 0.3 per 100000 population per year. There were significant racial differences in the incidence.
