Abstract
Treatment with intermittent positive pressure breathing (IPPB) and incentive spirometry (I.S.) was compared in 109 patients after heart surgery with cardiopulmonary bypass. Assessment was done by measurement of vital capacity, arterial oxygen tension and identification of the radiological signs of atelectasis. All patients were instructed pre-operatively in the treatment which was to be used. Vital capacity, arterial oxygen tension while breathing air for the first three postoperative days and the incidence of atelectasis showed no significant difference between groups. Ten minutes after treatment the arterial oxygen tension fell, but this was only statistically significant after I.P.P.B. At 60 minutes the arterial oxygen tension had returned to pretreatment level in both groups. The use of the incentive spirometer four times daily is no better than l.P.P.B. in preventing atelectasis after open-heart surgery. Possibly incentive spirometer treatment given more frequently may be more effective. On a comparé la spirométrie incitative aux traitements avec pression positive intermittente en phase post-opératoire chez 109 opérés à coeur ouvert. Les paramètres mesurés et comparés étaient la capacité vitale, la Pa02 et les signes radiologiques d’adélectasie. L’une ou l’autre méthode, selon le cas, était enreingée aux malades avant la chirurgie. Les capacités vitales et les Pa02 en respiration é 1’air ambiant, au cours des trois premiers jours aprés chirurgie, ainsi que f’incidénce d’atélectasie n’étaient pas différents de façon significative entre les patients des deux groupes. La Pa02 s’abaissait 10 minutes apres les traitements mais cette baisse n’était significative que dans le groupe traité avec la pression positive intermittente. Une heure aprés les traitements, ces Pa02 étaient comparables aux valeurs avant traitement. L’utilisation de spirométrie incitative quatre fois par jour n’est pas supérieure aux traitements avec pression positive intermittente comme méthode de prévention de l’atelectasie pulmonaire après chirurgie cardiaque. Peut-être la spirométrie incitative utilisée plus de quatre fois par jour serait-elle plus efficace.This publication has 15 references indexed in Scilit:
