Purpose
Intracranial hypotension due to cerebrospinal fluid leak is mainly the causal factor for the pathophysiology of postdural puncture headache (PDPH). In this study, we aimed to evaluate the effectiveness of optic nerve sheath diameter (ONSD) measurement in predicting the development of PDPH in patients undergoing spinal anesthesia.
Methods
According to the American Society of Anesthesiology (ASA) physical classification I–III, 83 patients aged 18–65 years scheduled for spinal anesthesia for elective surgery were included in the study. Demographic data (age, ASA, sex, smoking, migraine, and PDPH history) and operative data were recorded. Preoperative ONSD measurements were taken in the right and left eye, axial, and sagittal planes. The mean of four measurements was recorded before and 24 h after the spinal anesthesia.
Results
A total of 83 patients (59 males and 24 females) were included in the study. In our study, the rate of PDPH development was determined as 22.9% (n = 19). There was a statistically significant difference in the preoperative and postoperative ONSD values between patients with and without PDPH development (p = 0.046). In the receiver operating characteristic analysis, the area under the curve was 0.843, and the cutoff value was 0.4.
Conclusion
The difference between the ONSD values measured before and after spinal anesthesia may be an important parameter for predicting the risk of PDPH development.
