Usefulness of ultrasound-guided serratus-anterior block in prevention of postoperative pain after breast surgery. A cohort study
Authors' conclusion
Superficial serratus anterior plane blocks are effective and safe in pain control in the immediate postoperative period for breast cancer surgery as a part of the multimodal approach. No significant differences were found one week and one month after surgery.
Study context
- Population
- Adults undergoing breast oncological surgery
- Participants
- 195 adults
- Exposure
- GA combined with superficial serratus anterior plane block vs GA alone
- Group Ln = 99
- Group Gn = 96reference
- Outcome
- Postoperative pain intensity (EVN scale)
- Follow-up
- Immediate postoperative period, 24 h, 7 days and 1 month
