Not Applicable
- Conditions
- Patients who received epidural anesthesia during surgery
- Registration Number
- JPRN-UMIN000027843
- Lead Sponsor
- Department of anesthesia, Saiseikai Shiga hospital,Shiga, JAPA
- Brief Summary
The estimated intervertebral level and the confirmed intervertebral level confirmed perfectly between the 2 groups of the conventional method (group C) and predictive formula usage group (group S) were 32.2% for group C and 32.2% and 54.1% for group S(p = 0.00176). On the other hand, the concordance rate allowed up to +-1 vertebral discrepancy was 98.4% (p = 0.000195) in S group versus 76.3% in C group.

- Primary Outcome Measures
Name Time Method sing the prediction formula to calculate the length of the thoracic spine from body height, we determine the estimated position of the 12th thoracic spinous process of the participants. The epidural catheter is then indwelled from any intervertebral space with reference to that position. In the postoperative X - ray, the actual indwelling intervertebral space and the predicted intervertebral space are obtained. When the difference is 0, we determined as success, otherwise when deviation within the 1 vertebra, we determined as intermediate success. Between the cases of epidural puncture using prediction formula and puncture using other methods, that is, puncture using conventional method, we find success ratio and intermediate success ratio. The main evaluation item is the success ratio and the intermediate success ratio. It is judged whether there is a statistically significant difference in the success ratio between the two groups.
- Secondary Outcome Measures
Name Time Method We will process the influence of the background factor of the patient and that of participating doctors on the predictive value by multivariate analysis. We use this result as a secondary evaluation item.
