Brief Summary

More than 600,000 hysterectomies are performed in the United States each year, making it the most common non-obstetric major surgery performed on women1. Estimates suggest that at least 30% of hysterectomies are performed laparoscopically or robotically with an increasing trend toward minimally invasive approaches2. While a minimally invasive approach certainly provides improved recovery, patients still experience substantial pain and most require opiate medications for pain control. Incorporating a multimodal approach to postoperative pain management through the use of field nerve blocks is potentially an ideal way to enhance recovery and minimize the need for narcotic pain medications. Over the past decade, the use of Transversus Abdominis Plane (TAP) blocks as an adjunct for postoperative pain management has gained in popularity. First described in 2001 by Dr. Rafi of Limerick3, Ireland, TAP blocks are now typically performed by an anesthesiologist with the use of ultrasound guidance. The transversus abdominis plane is the neurovascular plane between the aponeurosis of the internal oblique and transversus abdominis muscles. Herein lie the afferent nociceptor nerve endings of T7-L1. Injection of a 20-30cc volume of anesthetic into this plane causes a sensory nerve block to the ipsilateral antero-abdominal wall from the costal margin to the symphysis pubis4. Clinical trials have documented the validity of using TAP blocks for both open and laparoscopic procedures and verified their use for postsurgical pain relief. Studies have demonstrated that TAP blocks for both open and laparoscopic hysterectomies are safe and efficacious5, 6. In 2011, De Oliveira et al. demonstrated improved quality of recovery for women undergoing preoperative ultrasound guided TAP infiltration with ropivacaine at the time of laparoscopic hysterectomy7.
