We investigated the potential positive effect of acetazolamide in reducing CSF leak after spine surgery. Materials and methodsWe conducted a single-center, double-blind, randomized-controlled trial comparing Oral Acetazolamide plus Corrected body (prone) position (CP+A) versus Corrected body (prone) position alone(CP−A) from January 2014 to September 2015 in the Neurosurgery ward of Shariati Teaching Hospital, Tehran University of Medical Sciences, Tehran, Iran. Seventy-two Patients divided into two groups [CP−A group (n=36, 50%) and CP+A group (n=36, 50%)] were randomly assigned to this Clinical Trial study. CP+A group (maintained the 3/4 lateral position+dose of acetazolamide 20mg/kg/day in 3–4 divided doses for 7 days), and CP−A group (Control group) (maintained the 3/4 lateral position for 7 days with no acetazolamide). ResultsBaseline characteristics between the two groups showed no significant differences: Sex (P<0.637), Age (P<0.988) and previous CNS operation at other location besides the spine (P<0.496). Although we reported post-surgical CSF leak in 2/36 (5.55%) of CP+A group and 4/36(11.11%) of CP−A (control) group, there was no significant difference observed between the two groups (95%CI, 0.081–2.748; OR=0.471; P<0.402; Adjusted P<0.247). Additionally, no significant differences were observed when we examined surgical characteristics, such as the size of the dural opening (P<0.489) and type of operation (P<0.465). ConclusionAcetazolamide has no positive effect in controlling CSF leak after dural opening/dural tear in adult patients who undergo spinal surgery, when we considered alongside the one-week prone position. Therefore, acetazolamide administration may not be essential for postoperative spinal surgery for dural tear. Prospective studies involving a larger sample size may be needed to track long-term acetazolamide complications on patients with CSF leak. ER -
