Comparative StudyPulsed Doppler echocardiography to assess pulmonary artery hypertension in chronic obstructive pulmonary disease.
Noninvasive assessment of pulmonary artery hypertension would be of great value in patients with chronic obstructive pulmonary disease (COPD). Although continuous wave Doppler echocardiographic measurement of right atrial to right ventricular pressure gradient is the most useful method of noninvasive assessment of pulmonary artery hypertension, this technique is often limited in patients with COPD. ⋯ AT and AT/RVET were significantly shorter in COPD patients (AT 92 +/- 4.3 ms; AT/RVET 0.38 +/- 0.03) as compared with healthy volunteers (AT 132 +/- 4.5 ms; p < 0.001; AT/RVET 0.46 +/- 0.02; p < 0.005), whereas RVET, PEP and PEP/RVET were not significantly different in both groups. A significant correlation was demonstrated between AT and PAPs (r = -0.76; p < 0.001) and PAPm (r = -0.82; p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Considerations on 200 cases of percutaneous cricothyroidotomy (minitracheotomy).
More than 10 yrs ago, minitracheotomy was suggested as an elective method in the treatment of sputum retention, resulting from impaired ability to cough, in many medical and surgical diseases. We report our experience of 200 cases of percutaneous cricothyroidotomy in our Intensive Care Unit (145 patients), and in other wards (55 patients). ⋯ About 60-70% of treated patients benefited by minitracheotomy and did not require more invasive interventions. A better control of technique, moreover, allowed other possible applications to be discovered.
