Abstract
An erratum was issued for: Noninvasive and Invasive Renal Hypoxia Monitoring in a Porcine Model of Hemorrhagic Shock. The Protocol section was updated.
Step 2.3.1 - 2.3.1.2 of the Protocol was updated from:
- Measure PuO2 in the bladder.
- Remove all air from the bladder by slowly squeezing the bladder while ensuring urine does not leak out.
- Place the tip of the luminescence quenching-based PuO2 sensor in the bladder via a cystotomy, similar to the catheter.
- Connect the fiber optic cable from the bladder sensor to the data collection device.
to:
- Measure PuO2 at the outlet of the bladder
- Identify the balloon on the catheter. Just below the balloon make an incision along the long axis of the catheter, ensuring that you do not cut the lumen that connects to the balloon.
- After making the incision, insert a t-connector that contains the sensing material into the incision.
- Use tissue glue to secure the t-connector in place.
- Connect the fiber optic cable from the bladder data collection device to the connector that contains the sensing material.
Step 2.3.2.2 - 2.3.2.7 of the Protocol was updated from:
- Make a flank incision large enough to expose the kidney (approx. 2-3 in) on the side of the pig at approximately the same location where the kidney was identified.
- With the tips of a retractor together, introduce the retractor into the incision and then spread the tips of the retractor to expose the kidney.
- Use a micro-manipulator or similar tool to hold the oxygen probe steady. If possible, attach this tool to the end of an articulating arm.
- Attach the other end of the articulating arm to the surgical table so that the other end that will hold the oxygen probe is near the opened incision. If the tool that is used to hold the oxygen probe is not connected to an articulating arm, position the tool so the oxygen sensor is near the opened incision and is stable.
- Unlock all articulating joints of the arm. Using ultrasound, place the tip of the oxygen probe in the medulla region of the kidney. Lock all articulating joints on the arm.
- After confirming placement of the tip of the sensor in the medulla with ultrasound, use the micromanipulator to retract the needle housing the luminescence-based oxygen sensor. Connect the other end of the sensor to the data collection device connected to the computer running the data collection software. Start recording.
to:
- Move the bowel so that you have a clear line of site and access to the entire kidney.
- Insert the sensor into 2" 18 gauge catheter. Adjust the luer lock connector on the sensor so that the tip of the sensor is exposed. Remove the catheter and place it over an 18 gauge needle.
- Place the 18 gauge needle and 2 in catheter into the renal medulla under ultrasound guidance.
- Remove the needle, keeping the catheter in place. Thread the tissue sensor through the catheter and use the luer lock to connect the sensor to the catheter.
- Use tissue glue to secure the catheter in place.
- Connect the tissue sensor to the data collection box.
