Aim: In this study, we aimed to show which parameter can be used to get a realible result in differentiation of cerebro spinal fluid (CSF) and saline by using the urine test strips. We compared the effectiveness of glucose and pH parameters by dripping CSF samples obtained from spinal needle during combined spinal-epidural anesthesia (CSEA) by means of glucose and pH regions of the urine test strip. Methods: After obtaining written consent, 70 patients scheduled for lower extremity surgery under CSEA were included in this unicenter and randomized clinical study. During the intervention, block levels and color changes in urine test strips' glucose and pH parameters were all recorded. Results: In both groups, urine test strip color change were positive in 34 patients and negative in 1 patient. There was no statistically significant difference. In our study, even free CSF flow was detected after CSEA implementation, block levels were detected as and ldquo;none and rdquo; in 3 patients in and ldquo;glucose and rdquo; group (9%) and 1 patient in and ldquo;pH and rdquo; group (3%). There was a statistically significant difference in comparison of block levels. Conclusion: We found out that CSF samples dripped on urine test strips caused a color change in glucose and pH parameters, similar to previous results. However there was no block levels in 1 patient in and ldquo;pH and rdquo; and 3 patients in and ldquo;glucose and rdquo; groups. We concluded that pH parameters are more reliable than glucose parameters in detecting CSF [TAF Prev Med Bull 2015; 14(3.000): 198-201]
