  • Look Inside

In attempt to define extubation criteria that everyone could practice easily and estimate objec-tively, we tried to score twelve factors of our cri-teria.

Between successed group in extubation and failed one, significant difference was found on six factors; 1. Normality on X-ray photograph of chest 2. Ability of lifting one's head 3. Normal respiratory rate (10/min≦R. R.≦30min) 4. Enough forced vital capacity (F.V.C.≧12/ml/kg) 5. R-index under 0.8 (R-index= AaDO2/PaO2) 6. Good ge-neral impression (They were scored 0 point.) In order to simplify the calculation of the score, a value of either 0 or 1 point was assigned to each of the six factors. Total scores of the six factors ranged from 0 to 6 points, increasing with severity of symptoms and signs. Total scores were signifi-cantly different (p<0.01) between successed group (1.11±1.0) and failed one (3.13±1.15). In successed group patients with total score under 2 points accounted for 90 percent and in failed one over 3 to 6 points accounted for 70 percent.

We concluded that patients with total scores under 2 points could be extubated successfully.
