Comparison of Ultrasound-Guided Thoracic Paravertebral Block Using Ropivacaine and Balanced General Anesthesia in Breast Surgeries.

Abstract

Background and Aims:Despite the latest advances in breast surgery, the procedure is frequently associated with postoperative pain, nausea, and vomiting, which leads not only to increased patient's suffering but also to a prolongation of hospital stays and related costs. Thoracic paravertebral block (TPVB) has been successfully used to provide analgesia for multiple thoracic and abdominal procedures in both children and adults.Methods:Forty patients were allocated for this observational, comparative study and divided into two groups of 20 each, namely thoracic paravertebral group (Group P) study group and general anesthesia (GA) group (Group G), control group, and observations made for duration of procedure, visual analog score, rescue analgesia, surgeon and patient's satisfaction, postoperative complications, and duration of postanesthesia care unit (PACU) stay in both the groups.Results:We found that there was a statistically significant difference in duration of procedure, more time was taken in performing TPVB. Pain was better controlled in Group P and requirement of rescue analgesia was higher in Group G patients, postoperative complications such as shivering, nausea, vomiting, and duration of PACU stay were more in patients receiving GA.Conclusion:Hence, we conclude that ultrasound-guided TPVB appears to be safe, reliable, and effective technique for breast surgeries with several advantages over GA in terms of long-lasting pain relief, fewer complications, and shorter hospital stay.
