Post Procedural Complication following Cervical Epidural Local Anesthetic Injection: A Case Report.

ABSTRACT: Cervical radiculopathy is a common condition affecting many people each year. The efficacy of cervical epidural steroid injection for patients that have not responded to conservative treatment has been demonstrated. Even with confirmatory radiocontrast dispersion indicating correct presence in the epidural space, there still may be rostral spread of steroid and local anesthetic resulting in an unusual presentation of symptoms and potentially life threatening complications.We present the case of a 52-year-old male presenting for a right sided C6-C7 epidural steroid injection. The epidural space was identified and a Tuohy needle was advanced using loss of resistance technique. Isovue contrast was used for needle localization and after confirmation of the presence of the contrast in the epidural space, dexamethasone and lidocaine were injected to the area without any complications. Five minutes after arrival to the PACU, the patient developed a constellation of symptoms including inability to swallow, vertigo, and horizontal nystagmus which required reassurance and vigilant monitoring.Interventional pain physicians must be cognizant that even with confirmatory epidural radiocontrast dispersion, there still may be inadvertent uptake of steroid and local anesthetic rostrally resulting in an unusual presentation of symptoms and potentially life threatening complications. Potential reasons for the rostral spread include inadvertent subdural or intrathecal injection.

Project description:Background:The rationale for injection of epidural medications through the needle is to promote sooner onset of pain relief relative to dosing through the epidural catheter given that needle injection can be performed immediately after successful location of the epidural space. Some evidence indicates that dosing medications through the epidural needle results in faster onset and improved quality of epidural anesthesia compared to dosing through the catheter, though these dosing techniques have not been compared in laboring women. This investigation was performed to determine whether dosing medication through the epidural needle improves the quality of analgesia, level of sensory blockade, or onset of pain relief measured from the time of epidural medication injection. Methods:In this double-blinded prospective investigation, healthy term laboring women (n=60) received labor epidural placement upon request. Epidural analgesia was initiated according to the assigned randomization group: 10 mL loading dose (0.125% bupivacaine with fentanyl 2 µg/mL) through either the epidural needle or the catheter, given in 5 mL increments spaced 2 minutes apart. Verbal rating scale (VRS) pain scores (0-10) and pinprick sensory levels were documented to determine the rates of analgesic and sensory blockade onset. Results:No significant differences were observed in onset of analgesia or sensory blockade from the time of injection between study groups. The estimated difference in the rate of pain relief (VRS/minute) was 0.04 (95% CI: -0.01 to 0.11; p=0.109), and the estimated difference in onset of sensory blockade (sensory level/minute) was 0.63 (95% CI: -0.02 to 0.15; p=0.166). The time to VRS ?3 and level of sensory block 20 minutes after dosing were also similar between groups. No differences in patient satisfaction, or maternal or fetal complications were observed. Conclusion:This investigation observed that epidural needle and catheter injection of medications result in similar onset of analgesia and sensory blockade, quality of labor analgesia, patient satisfaction, and complication rates.
