Effects of stellate ganglion block on intraoperative hemodynamic responses to pneumoperitoneum in adult patients undergoing laparoscopic cholecystectomy- Hospital based randomised controlled trail.

This is double blinded randomized controlled trial recruiting 60 participants equally divided into two groups of study and control. Study group participants will receive ultrasound guided right sided stellate ganglion block using 10ml of 0.75% Ropivacaine in the preoperatively 15 mins before surgery. Whereas control group participants will receive ultrasound guided right sided stellate ganglion block using 10 ml of normal saline as a placebo. All the participants are induced in under general anesthesia according to standard institutional protocols. Patient baseline vitals will be monitored before the block, during laryngoscopy, intubation, pneumoperitonuem,  5 mins, 10 mins, 15 mins, 20 mins, 30 mins intraoperatively. Heart rate and mean arterial pressure values will be statistically analysed in both the groups to extrapolate the results of the study.
