The purpose of the study is to determine if the administration of liposomal bupivacaine at the completion of a suburethral sling procedure will result in decreased postoperative pain compared to no injection.
The purpose of the study is to determine if the administration of liposomal bupivacaine at the completion of a suburethral sling procedure will result in decreased postoperative pain compared to no injection. The hypothesis is that administration of liposomal bupivacaine at the completion of retropubic suburethral sling procedure will result in decreased postoperative pain compared to no injection. Although multiple routes for sling placement exist, no difference in pain has been found when comparing obturator verses retropubic suburethral sling. Previous trials have investigated varying formulations of injections along the sling pathway in order to reduce complications such as pain and voiding dysfunction. Local anesthesia along the trocar pathway has shown some improvements in pain. Other techniques, however, have varying results. In 2011, the FDA approved liposomal bupivacaine as a single dose wound infiltration for treatment of postoperative pain following hemorrhoidectomy and bunionectomy. Initial studies demonstrated decreased pain compared to placebo, prolonged release in a bimodal distribution, and greater sensory than motor blockade. Additionally, postoperative benefits such as decreased overall pain, decreased opioid use, and increased time to opioid need were observed. Liposomal bupivacaine may also have the advantage of reducing hospital stays and decreasing overall hospital costs. The side effect profile has similar or improved rates of adverse events compared to traditional bupivacaine, a favorable cardiac profile, and no increased risk of poor wound healing. With such promise, we aim to evaluate the use of liposomal bupivacaine to reduce postoperative pain for the placement of slings to treat stress urinary incontinence. The study will be a blinded randomized controlled trial. Patients randomized to receive liposomal bupivicaine, the standard 20ml vial will be diluted with 1 Oml of saline to a reconstituted volume of 30 ml. Those in the control group will receive 30ml of normal saline injected in the same fashion as the study arm.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Liposomal Bupivacaine | Experimental | The placement of the retropublic sling will be placed in routine fashion under general anesthesia. If randomized to liposomal bupivacaine, the standard 20 milliliter (ml) vial (266mg dose) will be diluted with 10ml of preservative-free, sterile normal saline (0.9%) for injection to a reconstituted volume of 30ml. At the completion of the procedure, and at least 20 minutes after the injection of 30ml lidocaine with epinephrine (routine for the surgical procedure), those subjects in the liposomal bupivacaine arm will have the 30ml dilutional volume injected. 10ml will be injected into the vaginal epithelium in the mid-urethral area and 10ml will be injected into each of the trocar paths through the suprapubic incisions bilaterally. An aspiration and moving needle technique will be employed. |
|
| Saline Placebo | Placebo Comparator | The placement of the retropublic sling will be placed in routine fashion under general anesthesia. At the completion of the procedure, and at least 20 minutes after the injection of 30ml lidocaine with epinephrine (routine for the surgical procedure), those subjects in the saline placebo arm will receive 30ml normal saline injected. 10ml will be injected into the vaginal epithelium in the mid-urethral area and 10ml will be injected into each of the trocar paths through the suprapubic incisions bilaterally. An aspiration and moving needle technique will be employed. |
