Ultrasound-guided single thoracic paravertebral nerve block and erector spinae plane block for perioperative analgesia in thoracoscopic pulmonary lobectomy: a randomized controlled trial

Abstract

Abstract Objective To explore the effect of a single preoperative ultrasound-guided thoracic paravertebral nerve block (TPVB) and erector spinae plane block (ESPB) for perioperative analgesia in thoracoscopic pulmonary lobectomy. Methods Seventy-two patients aged 40–70 years who underwent thoracoscopic pulmonary lobectomy under general anesthesia were enrolled and randomly divided into the control group (Group C), the TPVB group (Group T) and the ESPB group (Group E). The primary observation indicators included the visual analogue scale (VAS) at 1, 6, 12, 24, and 48 h postoperatively at rest and with a cough. The secondary observation indicators included the intraoperative sufentanil consumption, anesthesia awakening time and extubation time, the sufentanil consumption in the analgesic pump, and flurbiprofen ester consumption for remedial analgesia within 48 h after surgery and the incidence of postoperative adverse events. Results The intraoperative sufentanil consumption, anesthesia awakening time, and extubation time were lower in groups T and E than those in group C (p < 0.05). Patients in group T had lower VAS scores at rest and with a cough at 1, 6, and 12 h postoperatively than in group C at the same time points (p < 0.05). The VAS scores at rest at 1 and 6 h postoperatively and coughing status at 1, 6, and 12 h postoperatively were lower in group E than in group C at the same time points (p < 0.05). Conclusion The ultrasound-guided preoperative single TPVB and ESPB for thoracoscopic pulmonary lobectomy could both reduce the postoperative pain VAS score and reduce the dose of perioperative sufentanil and postoperative remedial analgesics.
