Comparison between Bilateral Superficial Cervical Plexus Block & Local Infiltration with 0.5 % Ropivacaine for Postoperative Analgesia in Thyroidectomy Patients
Main Article Content
Abstract
Background: Thyroid surgery is a quite painful procedure performed in a sensitive skin area of the human body. Local anaesthetic wound infiltration, Bilateral Superficial Cervical Plexus Block are examples of regional anaesthesia. Present study was aimed to compare bilateral superficial cervical plexus block versus local infiltration with 0.5 % ropivacaine for postoperative analgesia in thyroidectomy patients.
Material and Methods: Present study was single-center, Prospective, double blinded, randomized controlled study., conducted in adult patients of either gender, ASA physical status II, undergoing elective thyroid surgeries under general anaesthesia, Patients were randomly divided into Group A (Wound infiltration) & Group B (bilateral superficial cervical plexus block - BSCPB).
Results: A total of 60 consecutive patients posted for thyroidectomy were enrolled. In this study female gender has comparatively undergone thyroidectomy more when compared to male. 76.7% had no pain during extubation in Group A whereas 46.7% had no pain during extubation. 73.3% study participants had no PONV in Group A and 50.0% study participants had no PONV in Group B. Patients from bilateral superficial cervical plexus block (BSCPB) required rescue analgesia later (655.67 ± 171.840) as compared to Wound infiltration group (332.67 ± 127.548), difference was statistically significant (0.005) Patients from Wound infiltration group required less rescue analgesia (3.10 ± 0.960) as compared to bilateral superficial cervical plexus block (BSCPB) (3.60 ± 1.102), difference was not statistically significant (0.066).
Conclusion: In thyroid surgeries ultrasound guided Bilateral Superficial Cervical Plexus block using 0.5% Ropivacaine 10 ml on either side after induction of general anaesthesia provided better postoperative analgesia when compared to wound site infiltration with 0.5% Ropivacaine.
