Summary
Brief summary (as posted)
Nephrectomy (kidney removal) is one of the most common surgical procedures in urologic practice. Recent advances in laparoscopic (keyhole) procedures have resulted in a significant decrease in open nephrectomies. Most laparoscopic surgeries are performed through 3 to 4 small (1 to 1.5 cm) incisions; however, laparoscopic nephrectomies for cancer include one of the incisions being extended to 7 to 10 cm for kidney removal. Although pain after laparoscopic surgery is somewhat less than that after open surgery, it is still significant, and opioid consumption is similar. Opioids have been a mainstay for the treatment of post-operative pain, but they are associated with many adverse effects and a potential for long-term use. Thus, combining opioid analgesia with other forms of analgesia has the potential to reduce opioid use. Paravertebral nerve blocks, where local anesthetic is injected near the spinal nerves, have recently shown good pain control in patients undergoing thoracic and abdominal surgeries. However, this technique is technically challenging, time consuming, and has the risk of significant side effects. Fascial plane blocks are an alternative to paravertebral blocks. Fascial plane blocks, where local anesthetic is injected in areas further away from the spinal nerves, are easier to perform than paravertebral blocks, and have fewer associated risks. A recently described fascial plane block, the Erector Spinae Plane (ESP) block, has been shown to be effective in controlling pain in a variety of surgeries. However, currently, there is little information regarding its use in laparoscopic nephrectomy. We are proposing this pilot randomized control trial to look at the feasibility of completing a larger randomized control trial to evaluate ESP blockade in patients undergoing laparoscopic nephrectomy for cancer. We will also investigate total opioid consumption, and pain scores at rest and during movement.

- type
- EXPERIMENTAL
- label
- Ultrasound-guided continuous ESP block with opioid PCA
- description
- A high-frequency linear ultrasound transducer will be placed in a longitudinal parasagittal orientation 3 cm lateral to the T7/T8 spinous process. The patient's skin will be anesthetized with 2% lidocaine. A Contiplex Echo ultra 360 18G needle with 20G × 55 cm Contiplex Echo catheter will be inserted using an in-plane superior-to-inferior approach to place the tip into the fascial plane on the deep (anterior) aspect of erector spinae muscle. The location of the needle tip will be confirmed by visible fluid spread lifting erector spinae muscle off the bony shadow of the transverse process. A total of 30 mL of 0.375% ropivacaine with 5mcg/mL of epinephrine will be injected in 5-mL aliquots through the needle (maximum of 3mg/kg) followed by insertion of the echo catheter system under direct vision 2-3 cm beyond the needle tip.

- The exact same procedure as the experimental group will be followed, substituting saline for local anesthetic at the same amounts and rate. As with the ESP group, the patients will have PCA initiated postoperatively in the PACU at the same doses.
