AbstractBackground: In recent years, interfacial plane blocks are used to reduce pain and opioid consumption for multimodal analgesia strategies. Serratus Anterior Plane (SAP) block is widely used clinical practice, in which local anesthetics are injected into the fascial plane superficial or deep to the serratus anterior muscle (SAM). This will block the lateral cutaneous branches of the intercostal nerves, this effectively relieving postoperative pain for procedures such as breast surgery, thoracoscopic surgery, rib fractures, and minimally invasive heart surgery.
Aim & Objective of the Study: The study aims to compare Serratus Anterior Plane Block between 0.125% Bupivacaine 20ml and 0.2% Ropivacaine 20ml for the duration of postoperative Analgesia.
Methods: The clinical study was conducted in the Department of Anaesthesiology at Rajah Muthiah Medical College and hospital, Annamalai University from December 2019 to September 2021. The study includes 40 adults patients coming for elective adult breast surgeries. Patients were assigned by random numbers into one of the two treatment groups: Serratus Anterior Plane block with 20ml Bupivacaine 0.125% (group B) and 20ml Ropivacaine 0.2% (Group R). The parameters monitored and recorded are heart rate, blood pressure,VAS score, and side effects. The results were subjected to statistical analysis.
Results: Heart rate variation between the groups, (group B and group R) at regular intervals from 0 mins to 24 hours is not statistically significant (p > 0.05). Systolic Blood Pressure variation between the groups (group B and group R) at regular intervals from 12 to 24 hours, is statistically significant (p <0.05). Diastolic Blood Pressure variation between the groups, group B and group R, at regular intervals from 0 to 24 hours, is not statistically significant (p >0.05). Duration of postoperative analgesia was prolonged in Group R 16.7±3.8 hrs when compared with Group B 9±1.7hrs. The p value was based on independent sample t test which gives a value of.
