Thoracic paravertebral nerve catheter reduces postoperative opioid use for vertebral body tethering patients

Vertebral body tethering is increasingly being performed, yet postoperative pain management has not yet been optimized. We sought to determine whether the addition of a thoracic paravertebral block in addition to a standard multimodal postoperative pain management program could provide greater pain relief, reduced analgesic requirement, and reduced length of stay.

Patients who underwent VBT at a single tertiary referral center were retrospectively reviewed. All patients received a single-shot intrathecal (IT) injection at the completion of the procedure in addition to a standardized multimodal pain management program. 45 patients received a thoracic paravertebral catheter with lidocaine infusion (TPVB) which was left in place for 4-6 days, whereas 24 control patients did not have a TPVB. Length of stay, maximum postoperative Numeric Pain Intensity Scale (NPIS), and total dose of opioids, ibuprofen, ketorolac and acetaminophen administered during hospitalization were evaluated.

69 patients met inclusion criteria. The mean cumulative dose of opioids administered during hospitalization was 148 oral morphine milligram equivalent (MME) in the control group vs. 47 MME in the TPVB group (p < 0.0001). Severe postoperative NPIS of ≥ 7 was reported in 9 out of the 24 control patients (38%) and in 13 out of the 45 patients (29%) who received a TPVB in addition to the standardized care (p = 0.46). There was no significant difference in the mean cumulative dose of NSAIDs (ibuprofen, ketorolac) consumed by the control group compared to the TPVB group (2632 mg vs. 1630 mg, p = 0.77). Mean length of stay in the control group was 3.8 vs. 3.0 days in the TPVB group (p < 0.001). There were no major complications associated with use of the TPVB.

In this series compared to controls, patients treated with a TPVB had reduced postoperative requirement of opioids and decreased length of hospital stay.
