Abstract

Objective:: To assess the safety and efficacy of the analgesic of unilateral erector spinae plane block (ESPB) in minimally invasive cardiac surgery (MICS). From November 2018 to July 2020, Subjects nad method: 30 patients aged 18-75, underwent minimally invasive cardiac surgery via the right thoracotomy with endoscopic support at the Vietnam National Heart Institute, Bach Mai Hospital. Ultrasound-guided right unilateral ESP catheter performed after general anesthesia for surgery, injected ropivacaine 0.5%; 20ml. At the end of surgery: patient received continuously ropivacaine 0.1% through the ESP catheter 0.2ml/kg/hour; combined with paracetamol intravenous infusion 1g every 6 hours; Patients were assessed for visual analogue scale (VAS) score at rest, during exercise at times within 72 hours after extubation, additional opioid consumption, and adverse events. Results: Effective in enhancing pain relief during surgery, the amount of fentanyl consumed was 212.51 ± 71.58 µg. Postoperative period the average VAS score at rest, and dynamic < 4; 5 patients (16.7%) needed additional intravenous PCA morphine, with the amount consumption in 24h, 48h, 72h, respectively: 4mg, 8mg, 14.2mg. In the study, there were no serious complications related to ESPB. Conclusion: ESPB provided effective analgesic for MICS via thoracic incision in reducing the VAS score and the morphine required. It is also a safe method with no severe ESPB-related complications.
