Reversal of Spinal Anesthesia Residual Motor Block Via Intrathecal Catheter: A Pilot Study
Beth Israel Deaconess Medical Center
Summary
The purpose of this study is to determine the feasibility of administering a predetermined amount of normal saline into the intrathecal or subarachnoid space via a small spinal catheter to reduce or eliminate the effects of previously injected spinal anesthetic following lower extremity orthopedic surgery.
Description
This is a prospective, randomized, interventional study to assess the feasibility and effectiveness of administering normal saline into the intrathecal or subarachnoid space through a small gauge epidural catheter via a single spinal needle to reverse residual anesthesia following lower extremity orthopedic surgery. This method is adapted from observations in obstetric populations where saline administered via the spinal catheter reduced headaches. This study investigates whether orthopedic patients will also receive unique benefits. Research procedures overview: * Randomization to intervent…
