ABSTRACT

It’s important to the anaesthesiologist to know and parse the concentrations of the end tidal carbon dioxide (ETCO₂), by means of a continuous survey of this variable in the patient under regional anaesthesia by a peridural lumbar blockade, because it has been seen that in the patient under regional anaesthesia plus sedation with benzodiazepines sometimes shows clinical alterations not corresponding with the clinical course expected during transanaesthesia. Patients and methods: 142 patients were studied in two groups of 71 each one. The group I received lumbar regional anaesthesia, and group II midazolam as sedation, was added. In both groups the patients were in dorsal decubitus, and monitoring with capnography and capnometry. Results: In patients of group II an important increase of the values of ETCO₂ at 20, 30 and 45 minutes was gotten. In patients of group I only and slight increase of such values was seen. Conclusions: This can be explained by the respiratory depression provoked by the benzodiazepine join to the patient’s position during surgery, so that it is mandatory the ETCO₂ monitorization in the patient undergone regional anaesthesia plus sedation.
