Effets de l’utilisation de la capnométrie en salle de surveillance post-interventionnelle : une étude randomisée monocentrique

Abstract : Introduction: there is a lack of data on the optimal value of capnometry in Post-Anaesthesia Care Unit (PACU) for recovering patients after general anaesthesia. However, this value could lead to changes in the ventilation applied by PACU nurses with consequences in recovery time, delay of extubation and length of stay in PACU. The goal of this study was to observe the effects of capnometry monitoring for intubated patients recovering from general anaesthesia in PACU. Methods: we conducted a monocentric, prospective, randomized study. In the group without accessible EtCO2 (« Capno- »), capnometry was monitored but not accessible to PACU’s staff. In the group with EtCO2, (« Capno+ ») capnometry was monitored and accessible to PACU’s staff. Patients had the same anesthesia protocol and were intubated, non-curarized and manually ventilated in PACU. Primary outcome was the rate of patients developping hypercapnia superior to 45 mmHg before extubation. Results : 48 patients were randomised in the two groups (24 patients per group). 20 patients (83,3%) developped hypercapnia before extubation in the « Capno – » group versus 13 patients (54,1%) in the « Capno + » group. This difference was statistically significant (p = 0,029). Conclusion: monitoring capnometry for recovering patients in PACU seems to reduce hypercapnia rate before extubation. This results should be confirmed by studies with larger population, and compared with ventilation protocols in PACU.
