Reversal of Spinal Anesthesia Residual Motor Block Via Intrathecal Catheter
Purpose
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.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
No Intervention Control |
Patients randomized to the control group will receive a combined spinal intrathecal catheter and the same dosing of spinal medications. All aspects of care and monitoring will be the same as non-study patients. The control group will not receive a dose of intrathecal saline post-op |

|
Experimental Saline administered via the intrathecal catheter |
Patients randomized to the Intervention group will be administered 10ml of sterile normal saline via the intrathecal catheter post-op prior to catheter removal. |

Detailed 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 intervention or control arm, - Use of 6-inch BD 20-gauge Quincke spinal needle, through which a B. Braun Perifix 24-gauge polyurethane catheter - Administration of normal saline - Administration of post-operative survey while in the PACU 1 hour - Follow-up survey 3 days post-surgery - Medical record review and abstraction.
