研究概览
简要总结
The purpose of this study is to compare the difference between two different pain control methods in patients who will be having a hysterectomy surgery. By collecting this data, we aim to show improved postoperative pain scores, decreased opioid needs, and decreased opioid side effects (nausea, sedation, ileus, urinary retention, respiratory depression).
详细描述
For the TAP block, the ultrasound probe is placed transverse to the abdominal wall, between the iliac crest and the costal margin. The needle is placed in the plane of the probe and advanced until it is between the internal oblique and the transversus abdominis muscles. Once in the plane, 2 mL of saline is injected to confirm needle position, then the local anesthetic solution is injected. [10]
For the ESP block, as mentioned previously, the ultrasound is positioned in a parasagittal fashion, 2-3 inches lateral to the spinous process. This approach visualizes the transverse process. The needle is inserted cranial-to-caudal to make contact with the shadow of the transverse process, with the needle tip deep to the fascial plane of the erector spinae muscle. Injection of saline confirms the location of the needle, and the anesthetic is injected.
All patients will receive PO acetaminophen and PO gabapentin the morning of surgery. Pt. will be placed on PRN oxycodone/acetaminophen (Percocet) postoperatively. PRN IV dilaudid may be given for severe breakthrough pain.
Opioid usage at 1, 24 and 48 hours after the block will be recorded by a member of the research team. Pain scores at rest and on movement will be measured by the investigator using Visual Analog Scale (VAS). Nausea will be measured using a categorical scoring system (none=0; mild=1; moderate=2; severe=3). Sedation scores will also be assessed by a member of the study team using a sedation scale (awake and alert=0; quietly awake=1; asleep but easily roused=2; deep sleep=3). All these parameters will be measured at 1, 24 and 48 hours after the blocks and patients will be encouraged to ambulate on postoperative day 1 under supervision. Their ambulation activity will be recorded.

研究组 & 干预措施
ESP Block
For the ESP block the ultrasound is positioned in a parasagittal fashion, 2-3 inches lateral to the spinous process. This approach visualizes the transverse process. The needle is inserted cranial-to-caudal to make contact with the shadow of the transverse process, with the needle tip deep to the fascial plane of the erector spinae muscle. Injection of saline confirms the location of the needle, and the anesthetic is injected (40 ml into each side; 20 ml injected at T8 and 20 ml injected at T12)
干预措施: Liposomal bupivacaine (Drug)

The needle is placed in the plane of the probe and advanced until it is between the internal oblique and the transversus abdominis muscles. Once in the plane, 2 mL of saline is injected to confirm needle position, then the local anesthetic solution is injected (40 ml into each side; 20 ml injected for subcostal TAP and 20 ml injected for posterior TAP).
