Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The paravertebral block is a technique that has been used perioperatively for breast (3,4), thoracic (5), abdominal (6), and hernia surgeries (7). It has also been used for pain control after rib fractures and penetrating trauma (8,9). The paravertebral block is performed by injecting local anesthetic above or below the transverse processes of the vertebral bodies where the spinal nerve roots emerge from the intervertebral foramina. The most common technique is to insert a needle 2.5 centimeters lateral to the spinous process at each level and "walk off" the transverse process. Injections at one or multiple levels block the somatic and sympathetic innervation to these dermatomes (10).
Rare complications of thoracic paravertebral blocks include epidural spread, intrathecal injection, and Horner's Syndrome (1,11,12). One of the most feared complications of the traditional technique is pleural puncture, which has an incidence of 0.64% to 6.7% in the published literature (3,11,13).
Ultrasound guidance in regional anesthesia is gaining widespread popularity. This technology provides visualization of key anatomic structures and has been shown to decrease block placement and onset times (14,15) and improve patient comfort (15). Ultrasound-guided blocks are associated with success rates of greater than 90% (15,16). In the thoracic region, ultrasound can be used to identify the vertebral transverse processes, as well as the ribs and the pleura of the lungs (17). In this way, pleural puncture can be avoided during paravertebral block placement.
To date there have been no published prospective, randomized trials comparing the multiple injection thoracic paravertebral technique using ultrasound guidance to general anesthesia in breast cancer surgery patients.
Our hypothesis is that paravertebral block anesthesia will result in shorter Post Anesthesia Care Unit (PACU) stays and decreased Visual Analog Scale (VAS) scores when compared to general anesthesia in patients undergoing breast cancer surgery. Secondary endpoints will include the need for postoperative opioids and the presence of nausea and/or vomiting.

Paravertebral Block
Patients receiving Paravertebral Block.
Paravertebral Block
Sedation will be provided with midazolam and fentanyl. The transverse processes of T1-T6 will be located using ultrasound guidance. The area will be prepped with betadine. At each level, a 21 Gauge, 4-inch Stimuplex needle will be inserted in order to make contact with the transverse process. Once the transverse process has been located, the needle will be "walked off" the process and inserted 1 cm deep to its inferior border. After negative aspiration, 3 mL of 1.5% mepivacaine with epinephrine 1:200,000 and bicarbonate and 3 mL of 0.5% bupivacaine with epinephrine 1:200,000 will be injected. Sedation will be provided with 50-100 mcg/kg/min of propofol during the surgical procedure. Approximately 20 minutes before the end of the procedure, 4 mg of zofran will be administered.
General Anesthesia
Patients receiving General Anesthesia.
General Anesthesia
Patients in the general anesthesia group will receive midazolam preoperatively for anxiolysis. Anesthesia will be induced with propofol and fentanyl. An LMA will be inserted and anesthesia maintained with sevoflurane in air and oxygen. 4 mg of zofran will be administered approximately 20 minutes before the end of the surgical procedure. The LMA will be removed and the patient will be transported to the PACU at the conclusion of the surgery.
