Clinical Trial Summary

This is a randomized, double-blinded, placebo-controlled trial of serratus plane blocks in subjects undergoing outpatient unilateral or bilateral breast surgery. Ninety subjects will be enrolled into the study at presurgical testing. Subjects will be stratified based on surgery type and randomized to receive a serratus plane block with either bupivicaine HCL or placebo. All patients will receive standard intraoperative anesthesia and standard postoperative pain control. The primary endpoint is the amount of opioid administered postoperatively. Secondary endpoints include postoperative pain intensity at timed intervals, amount of opioid administered intraoperatively and postoperatively, incidence of nausea and vomiting, time to discharge and patient satisfaction

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Postoperative Opioid Requirements	Postoperatively, oral and IV rescue medication will be administered to both groups upon request as per standard of care. The use of narcotics will also be recorded intra-operatively, for the duration of PACU and hospital stay and up until the end of postoperative day one. Consumption of rescue medication will be converted to the morphine equivalent (ME) dose for analysis.	4 to 10 hours
Secondary	Postoperative Pain With Numeric Rating Scale	Postoperatively, pain intensities at rest and on movement will be assessed every 30 minutes in the PACU for the first four hours and at hourly intervals up until PACU discharge, using the visual analog scale (VAS) with two anchor points; 0 being no pain and 10 being the worst pain imaginable. Pain scores were combined to find the mean and standard deviation.; The study will collect pain and scores in the PACU every 30 minutes up to 4 hrs and at 1 hr intervals after 4 hours for the duration of PACU stay.	every 30 minutes in the PACU for the first four hours and at hourly intervals up until PACU discharge, up to 10 hours.
Secondary	Postoperative Nausea and Vomiting With Verbal Rating Scale	Nausea assessed at time intervals with numeric rating scale and episodes of vomiting and retching recorded.; Evaluation will be performed at every 30 minutes in the PACU for the first four hours and at hourly intervals up until PACU discharge using a standard 11-point verbal rating scale, for which "0" represents "no nausea" and 10 represents "worst nausea imaginable." Nausea and vomiting scores were combined to find the mean and standard deviation.; The study will collect nausea and scores in the PACU every 30 minutes up to 4 hrs and at 1 hr intervals after 4 hours for the duration of PACU stay.	every 30 minutes in the PACU for the first four hours and at hourly intervals up until PACU discharge, up to 10 hours.
Secondary	Number of Participants Who Required Antiemetics During the Postoperative Period.	Number of Participants who Required Antiemetics During the Postoperative Period.	4 to 10 hours
Secondary	PACU Length of Stay	Time to PACU discharge	0 to 10 hours
Secondary	Patient Experience and Satisfaction With a 5-point Categorial Scale	This survey assessed patient experience and satisfaction. The scale ranged from "Very dissatisfied" or "1" was the minimum value. "Very satisfied" or "5" was the maximum value.	1 week
