Abstract

Objective: To see if PETCO₂ reflects PaCO₂ with acceptable accuracy. Methods: In this audit the anaesthetic chart of fifty consecutive patients, age 12 years and above undergoing craniotomy for intracranial pathology, were reviewed. Results: The difference between end tidal carbon dioxide (ETCO₂) value corresponding to the time of taking the arterial sample and the PaCO₂ was calculated. The mean end tidal CO₂ was 29.3± 2.8 and the mean PaCO₂ was 32.63± 4.5. The mean difference between the two values was calculated as 4.09 ± 3.0. The regression coefficient was 0.496, which showed a moderate association. A wide variability was observed in the results. Conclusion: Based on our results we recommend that arterial samples should be taken to determine PaCO2 in neurosurgical patients where maintenance of cerebral blood flow is crucial e.g. cerebral aneurysm surgery.
