Relation between transdiaphragmatic pressure and oxygen consumption in patients with intestinal obstruction

  • 1798 Accesses

Background and goals

Dysfunction of the diaphragm generally causes an additional load on other respiratory muscles [1]. It may be expressed by the increased oxygen cost of breathing and oxygen consumption (VO2) [2]. The increased abdominal pressure in patients with an intestinal obstruction may cause the dysfunction of the diaphragm.

Materials and methods

We studied the relation between VO2 and the end tidal transdiaphragmatic pressure (PdiET) in 16 patients with the diagnosis of an intestinal obstruction. The investigations were carried out after operation and before extubation. The average age of the patients was 41 ± 12. The same technique of anesthesia was performed in all patients. The APACHE II count was 22 ± 3. The device Capnomac Ultima- measured VO2.

Results

The relation between PdiET and VO2 are submitted in the Figure.

Conclusion

The patients with an intestinal obstruction demonstrate the moderate linear correlation (r = 0.63) between PdiET and VO2.
