100cc normal saline is injected into the subcutaneous layer for the initial flap dissection.

1 mg/mL 1cc epinephrine is diluted in 100cc normal saline and then 7.5 mg/mL 30cc ropivacaine is diluted in the same normal saline. The mixture is injected into the subcutaneous layer for the initial flap dissection.

To assess the pain relief and the hemodynamic stability of ropivacaine with epinephrine in BABA endoscopic and robotic thyroidectomy.

Diluted ropivacaine with epinephrine is injected into the subcutaneous space to relieve pain and reduce bleeding during procedures. The synergistic effect of ropivacaine with epinephrine can contribute to patients' welfare, such as relieving pain and structuring the hemodynamic stability.

Efficacy of Ropivacaine (With Epinephrine) in BABA Endoscopic and Robotic Thyroidectomy

Phase 3 Study of Ropivacaine (With Epinephrine) in BABA Endoscopic and Robotic Thyroidectomy

The numerical rating scale is utilized to assess the postoperative pain change for the first 12 hours according to location.

Range: 0(minimal pain, better outcome) \~ 10(maximum pain, worse outcome)

Unlike the general NRS pain score as reported in the "post-operative 48 hour" result which deals with post-operative discomfort in general, this outcome measures the pain score of the specific location in which flap dissection had taken place.

The maximal systolic blood pressure is monitored during surgery.

The maximal diastolic blood pressure is monitored during surgery.

The maximal heart rate is monitored during surgery.

The blood loss amount is estimated at the end of surgery.

1. Single-institution study
2. We did not directly examine the vasoconstrictive properties of epinephrine in helping reduce bleeding.
3. Issue regarding importance of statistical vs. clinical significance of the pain score remains to be addressed
