Parameters Related to Lumbar Puncture Do not Affect Occurrence of Postdural Puncture Headache but Might Influence Its Clinical Phenotype

Abstract

Background: Post-dural puncture headache (PDPH) has been the most common complication of diagnostic and therapeutic lumbar puncture (LP). The occurrence and clinical features of PDPH in relationship to different demographic, clinical, and paraclinical parameters and parameters related to LP were assessed. Methods: We conducted a cohort, prospective, single-center study of 252 consecutive patients (105 men and 147 women; average age, 47.3 ± 15.0 years), who had undergone LP for different medical reasons from February 2018 to June 2018 at the Clinic for Neurology Clinical Center of Serbia (Belgrade, Serbia). Results: Of the 252 patients, PDPH was reported in 133 (52.8%). The incidence of PDPH was more frequent in women (64.7%; P = 0.043). Univariate analyses identified the following significant risk factors for PDPH: female gender (odds ratio [OR], 1.74; 95% confidence interval [CI], 1.05–2.89), age (OR, 0.95; 95% CI, 0.94–0.97), smoking duration (OR, 0.91; 95% CI, 0.88–0.95), preexisting headaches (OR, 2.40; 95% CI, 1.39–4.17), circulatory system disease (OR, 0.52; 95% CI, 0.29–0.92), and musculoskeletal system and connective tissue disease (OR, 0.31; 95% CI, 0.12–0.81). In the multivariable model, duration of smoking and preexisting headaches remained independent risk factors for PDPH (OR, 0.93; 95% CI, 0.88–0.97; P = 0.002; and OR, 4.23; 95% CI, 1.27–14.08; P = 0.019, respectively). For various PDPH characteristics, significant risk factors were identified, including age, female gender, body mass index, circular or endocrine system diseases, and the use of caffeinated drinks before LP. In addition, the caliber of the traumatic needle, direction and number of needle stitches during LP, occurrence, intensity, and radiation of pain during LP, volume of sampled cerebrospinal fluid, rest and hydration after LP, preexisting headache, and earlier PDPH were significant. All these models were well-calibrated (Hosmer-Lemeshow test, P > 0.05). Conclusion: The results of the present study are important for the prediction of the occurrence of PDPH and the differential diagnosis of headaches after LP. © 2019 Elsevier Inc.
