Aim As the rates of complications related to tracheostomy procedures have fallen in recent years, the routine taking of pulmonary radiographs following tracheostomy has become a matter of debate. The aim of this study was to compare the incidence of complications developing in 120 children who had pulmonary radiographs taken following surgical tracheostomy and to thereby evaluate the necessity of routine pulmonary radiographs after tracheostomy. Methods The data were retrospectively reviewed of 120 children who had pulmonary radiographs taken following surgical tracheostomy between January 2012 and January 2018. The pulmonary radiographs taken before and immediately after tracheostomy were evaluated independently by two paediatric radiology specialists and the results were recorded. Results The incidence of complications after tracheostomy was determined as 23.3%, and no pneumothorax was determined in any patient. An increase was not seen in the complication incidence in those who had undergone emergency tracheostomy and patients aged < 2 years, which are accepted as high-risk groups. In the evaluation of the pre- and post-tracheostomy radiographs, new findings were determined on the post-tracheostomy radiograph that had not been there previously in eight patients (6.6%). These findings were newly formed infiltration in seven patients (5.8%), and malposition of the tracheostomy tube in one patient (0.8%). No pathology requiring intervention was determined on the radiographs of any patient. Conclusion The results of this study support the view that it is not necessary to take pulmonary radiographs routinely following tracheostomy in the paediatric age group, including those at higher risk.

Objective. To review the technical principles of transcutaneous Po2 (tcPo2) monitors and pulse oximeters and to discuss methodological and practical issues related to the use of these devices in infants and children. Design. Literature review and summary of personal experience. Results. tcPo2 measurements are influenced by skin thickness, sensor temperature, amount of contact gel used, and state of peripheral perfusion. The average in vivo response time to a rapid decrease in Pao2 is approximately 16 seconds. Sensitivity to both hypoxemia (Pao2 &lt; 50 mm Hg) and hyperoxemia (Pao2 &gt; 80 to 100 mm Hg) is approximately 85%. Pulse oximeters require careful sensor placement (to avoid optical shunts) and adequate pulse pressures (&gt; 20 mm Hg). They are prone to movement artifact. There are considerable differences in bias and precision between different brands, resulting, for example, in quite different upper alarm limits required to detect hyperoxemia reliably. The normal range of oxygen saturation measured by pulse oximetry, measured with one brand of pulse oximeter (Nellcor) during regular breathing, is 95% to 100% in preterm infants and 97% to 100% in full-term infants and children. Conclusions. Because both devices have their specific shortfalls, they should ideally be used in combination, particularly in critically ill preterm neonates. Where this is not feasible or necessary, clinicians must be aware of the limitations of the device they are using.
