Brief summary

The purpose of the study is to evaluate the effectiveness of EXPAREL in a transversus abdominis plane block by assessing the demand of postoperative narcotic, length of hospital stay and incidence of postoperative complications.

Interventions

DRUGExparel

In this arm as described above the intervention will be TAP block injection under ultrasound guidance using Exparel.

Design outcomes

Primary

MeasureTime frameDescription
Postoperative Pain Scoreparticipants will be followed for the duration of hospital stay, an expected average of 4 daysPatient will be evaluate for their post operative pain by nurses using visual analog scale from 0 to 10, zero means no pain, 10 is the worst pain can patient ever experience.

Secondary

MeasureTime frameDescription
Postoperative Narcotic Useparticipants will be followed for the duration of hospital stay, an expected average of 4 daysWill be measured, by converting all narcotic medicine used during postoperative period to equal morphine in mg, a calculator created by our pharmacy expert is able to convert any narcotic medicine such as fentanyl, oxycodone, hydromorphone, to morphine in mg. By doing that will have one variable to compare to the two groups.

MeasureTime frameDescription
Postoperative Complications.participants will be followed for the duration of hospital stay, and 30 days after discharge.Any postoperative complications within 30 days of procedure, including death will be recorded.
Length of Hospital Stay.participants will be followed for the duration of hospital stay, an expected average of 4 daysLength of hospital stay will be measured in number of days patient spends in the hospital from the day of procedure till discharge.
