Serratus Plane Block in Preventing Postoperative Pain of Mastectomy

Not Applicable

Completed

• Conditions: Breast Cancer; Serratus Plane Block; Chronic Pain

• Registration Number: NCT03615430
• Lead Sponsor: Feng Xia

Brief Summary

A prospective, double-blinded randomized controlled, 1-year follow-up study was designed to compare the analgesic effect of serratus plane block (SPB) after breast cancer surgery. Women undergoing radical mastectomy were dIvided into Control group and SPB group. The postoperative acute pain was evaluated by numerical rating scale (NRS) and the effect of preventing chronic pain was assessed at 3, 6, 12 months after surgery by NRS.

Primary Outcome Measures

Name	Time	Method
Numerical Rating Scale (NRS) of chronic pain	3 months after surgery	Pain intensity of patients was evaluated by Numerical Rating Scale, rating from 0 (no pain) to 10 (extreme pain) in order to evaluate the effect of SPB in preventing chronic pain

Secondary Outcome Measures

Name	Time	Method
Morphine consumption	0-24 hours after operation	extra need of analgesic
the change trend of Numerical Rating Scale (NRS) after surgery	0-24 hours after operation	Pain intensity of patients was evaluated by Numerical Rating Scale, rating from 0 (no pain) to 10 (extreme pain) in order to evaluate the analgesic effect of SPB
