Objectives:
To assess the safety and efficacy of ultrasound-guided high thoracic erector spinae plane block (HT-ESPB) in the management of post-thoracotomy ipsilateral shoulder pain (PTISP).
Design:
Randomized, double-blind, parallel-group, controlled, clinical trial.
Setting:
The National Cancer Institute.
Participants:
Seventy-six adult patients undergoing thoracic cancer surgery.
Interventions:
Patients were randomized into two equal groups: A control group received thoracic epidural analgesia (TEA) alone (TEA group), and a study group received ultrasound-guided HT-ESPB plus TEA (ESPB group).
Measurements And Main Results:
Outcomes included the incidence of PTISP, time to first rescue analgesia and total rescue analgesic doses for ISP, intraoperative fentanyl consumption, heart rate, mean arterial pressure, oxygen saturation, and complications. The ESPB group had a significantly lower incidence of ISP in the first postoperative hour compared to the TEA group (60.5% v 97.4%, p < 0.001). The ESPB group also exhibited lower postoperative visual analog scale scores, longer time to first rescue analgesia, and a reduced number of rescue analgesic doses for ISP, as well as lower heart rate and mean arterial pressure. No significant complications were reported.
Conclusions:
Ultrasound-guided HT-ESPB is a safe and efficacious strategy for the management of PTISP. It demonstrated a significant reduction in the incidence and severity of ISP and postoperative analgesic requirements when compared to TEA alone. This approach enhanced hemodynamic stability without significant complications.
