Long Term Oxygen Therapy

Long term oxygen therapy (LTOT) has been shown to improve the survival rate in Chronic Obstructive Pulmonary Disease (COPD) patients with severe resting hypoxemia by NOTT and MRC studies, published more than 25 years ago. The improved survival was found in patients who received oxygen for more than 15 hours/day. The effectiveness of LTOT has been documented only in stable COPD patients with severe chronic hypoxemia at rest (PaO255%. In fact no evidence supports the use of LTOT in COPD patients with moderate hypoxemia (55<PaO2<65 mmHg), and in those with decreased oxygen saturation (SO2<90%) during exercise or sleep. Furthermore, it is generally accepted without evidence that LTOT in clinical practice is warranted in other forms of chronic respiratory failure not due to COPD when arterial blood gas criteria match those established for COPD patients. The prescription of oxygen in these circumstances, as for unstable patients, increases the number of patients receiving supplemental oxygen and the related costs. Comorbidities are likely to affect both prognosis and health outcomes in COPD patients, but at the moment we do not know if LTOT in these patients with complex chronic diseases and mild-moderate hypoxemia could be of any use. For these reasons a critical revision of the actual guide lines indications for LTOT in order to optimise effectiveness and costs, and future research in the areas that have not previously been addressed by NOTT and MRC studies, are mandatory.

Long Term Oxygen Therapy

Background: Proper adjustment of arterial oxygen saturation (SaO2) during daily activities in patients with interstitial lung disease (ILD) requiring long-term oxygen therapy is challenging. Given the multifactorial nature of the limited exercise tolerance in patients with ILDs, the isolated use of oxygen therapy may not be enough. As demonstrated previously in patients with chronic obstructive pulmonary disease, the use of a noninvasive ventilation (NIV) device combined with oxygen therapy may prevent the falling of oxygen saturation during exercise, due to an improvement of the ventilation–perfusion ratio and a reduction of the respiratory work, thus enhancing exercise tolerance. We sought to assess in patients diagnosed with ILD who are in need of oxygen therapy, the effect of associating an NIV to improve oxygen parameters and the distance covered during the 6 min walking test (6MWT). Methods: We conducted a prospective observational study in patients with ILDs. After a clinical characterization, we performed a 6MWT in two different situations: using a portable oxygen concentrator with the regular flow used by the patient during their daily life activities and afterwards adding the additional support of a NIV. The oxygen saturation parameters were registered with a portable oximeter. Results: We included 16 patients with different ILDs who have oxygen therapy prescribed. The use of NIV associated with oxygen therapy in comparison with the use of oxygen therapy alone showed an increase of the average SaO2 [91% (88–93) versus 88% (86–90%); p = 0.0005] and a decrease in the percentage of time with oxygen saturation <90%: 36% (6–56%) versus 58% (36–77%); p < 0.0001. There were no changes in the 6MWT distance: 307 m (222–419 m) versus 316 m (228–425 m); p = 0.10. Conclusions: In our study the use of a NIV system associated with long-term oxygen therapy during exercise showed beneficial effects, especially improvement of oxygen saturation.

Using Data

The incidence of medical diseases in surgical patients was assessed using data gathered from 5944 consecutive anaesthetics. Medical disease which might affect anaesthetic management was present in 23.2% of patients. The commonest diseases were hypertension, anaemia, chronic obstructive airway disease, diabetes mellitus, and pulmonary tuberculosis. No significant difference was detected in sex incidence for ischaemic heart disease and cerebrovascular disease. There was a disproportionate preponderance of males with respiratory diseases. It is suggested that anaesthetics should be administered only by qualified anaesthetists, that the establishment of anaesthetic outpatient clinics is desirable, and that internal medicine should be included in anaesthetic training.
