Intrathecal analgesia involves implanting a catheter into the subarachnoid space at the vertebral segment corresponding to the painful site through a puncture procedure under local anesthesia. The injection port is placed subcutaneously and connected to the catheter. Analgesics can be delivered to the subarachnoid space via the injection port for targeted drug administration, thereby achieving the goal of pain relief.
The analgesic efficacy of intrathecal morphine is approximately 100 times that of intravenous administration and about 300 times that of oral administration
