Utility of bilateral superficial cervical plexus block in thyroidectomy patients for post-operative analgesia

Background: Thyroidectomy is painful procedure hence multimodal analgesia is required. Superficial cervical plexus block can be used for analgesia in thyroid surgeries. USG guided cervical plexus block administration is safe and latest technique as a part of multimodal analgesia for thyroid surgery.Methods: After obtaining consent 60 ASA grade I-II adult patients undergoing elective thyroid surgery were included and randomly divided into two groups (group B)-0.25% bupivacaine and (group S)-normal saline. Induction and maintenance under general anesthesia carried out as per standard protocol. After Induction USG guided block was administered with the drug solution as per allocated group. After surgery, patients were extubated and shifted to recovery room. Vital parameters were monitored. Patients were asked about their pain based on the 11-point numerical rating scales (NRS) score. The NRS score and other variables were documented at 3rd hour, 6th hour, 12th hour, and 24th hour at wards after the end of surgery. Time since the end of surgery to the first analgesia request was documented together with total analgesia consumed in the first 24 hours. If NRS score was ≥4 inj. Tramadol iv in incremental doses of 25 mg was given until pain relieved.Results: Time to first dose of analgesia was higher in group B compared to group S. Total analgesic dose of tramadol during first 24 hours was lower in group B compared to group SConclusions: bilateral superficial cervical plexus block can be used as a part of multi-modal analgesia in patients of thyroidectoy.

Ultrasound-guided bilateral superficial cervical plexus block enhances the quality of recovery of uremia patients with secondary hyperparathyroidism following parathyroidectomy: a randomized controlled trial

Background Parathyroidectomy has been proposed as a method for reducing parathyroid hormone levels. We evaluated the effects of ultrasound-guided bilateral superficial cervical plexus block (BSCPB) on the quality of recovery of uremia patients with secondary hyperparathyroidism (SHPT) following parathyroidectomy. Methods Eighty-two uremia patients who underwent parathyroidectomy and exhibited SHPT were randomly allocated to the BSCPB group or the control group (CON group). The patients received ultrasound-guided BSCPB with 7.5 ml of ropivacaine 0.5% on each side (BSCPB group) or equal amount of 0.9% normal saline (CON group). The primary outcome of the Quality of Recovery-40(QoR-40) score was recorded on the day before surgery and postoperative day 1(POD1). Secondary outcomes including total consumption of remifentanil, time to first required rescue analgesia, number of patients requiring rescue analgesia, and total consumption of tramadol during the first 24 h after surgery were recorded. The occurrence of postoperative nausea or vomiting (PONV) and the visual analogue scale (VAS) scores were assessed and recorded. Results The scores on the pain and emotional state dimensions of the QoR-40 and the total QoR-40 score were higher in the BSCPB group than in the CON group on POD1 (P = 0.000). Compared with the CON group, the total consumption of remifentanil was significantly decreased in the BSCPB group (P = 0.000). The BSCPB group exhibited longer time to first required rescue analgesia (P = 0.018), fewer patients requiring rescue analgesia (P = 0.000), and lower postoperative total consumption of tramadol during the first 24 h after surgery (P = 0.000) than the CON group. The incidence of PONV was significantly lower in the BSCPB group than in the CON group (P = 0.013). The VAS scores in the BSCPB group were lower than those in the CON group at all time-points after surgery (P = 0.000). Conclusion Ultrasound-guided BSCPB with ropivacaine 0.5% can enhance the quality of recovery, postoperative analgesia, and reduce the incidence of PONV in uremia patients with SHPT following parathyroidectomy.
