Does Bed Rest or Fluid Supplementation Prevent Post–Dural Puncture Headache?

The review included 24 trials with 2,996 participants. Of these, 12 trials provided moderate-quality evidence of increased incidence of post–dural puncture headache with bed rest compared with immediate mobilization (RR 1.24; 95% CI 1.04 to 1.48). Furthermore, 18 trials similarly provided moderate-quality evidence that bed rest increased incidence of any headache compared with immediate mobilization (RR 1.16; 95% CI 1.02 to 1.32). Subgroup analyses based on indication for dural puncture, including diagnostic lumbar puncture, myelography, and spinal anesthesia, found no decreased incidence of post–dural puncture headache with bed rest.
