OBJECTIVE: To provide physicians, physiotherapists, nurses and respiratory therapists with guidelines for the application of airway suctioning. DESIGN: This clinical practice guideline was developed using the model by Browman and colleagues. A working group of representatives from four professional colleges (nurses, physicians and surgeons, physiotherapists and respiratory therapists) and research experts was formed to conduct a systematic review, develop evidence-based recommendations and generate clinical practice guidelines. MEDLINE (1966 to 1998), CINAHL (1982 to 1997) and EMBASE (1974 to 1996) as well as the reference lists of identified articles were searched. Inclusion of articles was determined by at least two group members, and studies were classified according to type. Randomized, controlled; randomized; and nonrandomized crossover and comparative cohort trials were grouped by type of intervention and population for use in the development of recommendations. Other observational and animal studies dealing with adverse effects of suctioning were included in the review but were not used in the development of recommendations. Input on the evidence-based recommendations was sought and incorporated from members of all four professions and from experts on content and methodology. SETTING: Any setting (hospital or home) where suctioning is performed. POPULATION: Intubated and nonintubated adults, infants and children. RESULTS AND CONCLUSIONS: An attempt was made to develop recommendations in each of the subcategories of suctioning techniques addressed by at least one study. In some subcategories, definite recommendations were made (13 in adults, and three in children and infants); in other subcategories, insufficient evidence precluded recommendations. The recommendations addressed the following aspects of suctioning: preoxygenation, hyperinflation, insufflation, hyperoxygenation, hyperventilation, saline instillation, adaptor use, medication use, open and closed systems, and various types of catheters.

Use of restraint devices to prevent collision injuries and deaths among welfare-supported children.

Evidence that death and injury rates for young children involved in automobile collisions could be reduced if children were restrained prompted the State of Tennessee to pass the nation's first child passenger law, a law that became effective in January 1978. Although similar laws have now been enacted throughout the United States, usually restraint devices are not provided to low-income groups who may have difficulty affording them. Few studies have examined the use of such devices by welfare recipients. A total of 56 black women, receiving Medicaid and residing in inner city Memphis, were interviewed about their use of passenger restraints during automobile travel for their children ages 0-3 years. About two-thirds of the mothers interviewed said they rarely or never used child passenger restraint devices when transporting their child. Children age 3 years were significantly less likely to be transported in child restraint devices than younger children. Women who had received welfare payments for 3 years or more or who made fewer than one automobile trip a week with their child were significantly less likely to use child passenger restraints. These results suggest that, in spite of child passenger laws, automobile restraint devices are not used for a high percentage of children ages 0-3 years receiving medical care under State and Federal Medicaid programs. Since treatment costs are paid under these programs when children are injured in collisions, program administrators may have strong incentives to increase the proportion of these children being restrained while traveling in motor vehicles.

Controlled supplemental oxygenation during tracheobronchial hygiene.

The effect of controlled supplemental oxygenation without bag ventilation on transcutaneous partial pressure of oxygen (TcPO2) measurements during tracheobronchial hygiene was evaluated. Procedure A, no supplemental oxygenation, was compared to Procedure B, in which controlled supplemental oxygenation was used. For controlled supplemental oxygenation, the FiO2 was increased until TcPO2 measurements rose to levels between 90 and 100 torr. Sixteen premature infants who required mechanical ventilation were studied in the neonatal center. Both procedures were performed on each patient in random order. In both procedures, a precipitous decrease in TcPO2 was observed during chest vibration, and further decrease in TcPO2 was noted with endotracheal suctioning. Except for baseline readings, throughout the tracheobronchial hygiene TcPO2 measurements were significantly higher and more subjects maintained TcPO2 values greater than 40 torr in Procedure B. In Procedure A corresponding TcPO2 measurements were 40 torr or less. Mean recovery time was shorter in Procedure B, 2.1 +/- 2.3 minutes, than in Procedure A, 4.9 +/- 2.8 minutes, p less than .003. Thus, in most patients, controlled supplemental oxygenation without manual bag ventilation seems sufficient to prevent hypoxia during tracheobronchial hygiene; it also shortens recovery time from hypoxemia as a result of the bronchopulmonary hygiene procedure.
