- Brief Summary
Open Gastrectomy surgery is a big surgery with upper umbilical median incision where the postoperative pain is occur frequently. pain managements of this surgery with intravenous opioid analgesics are currently standard approach. but its side effects as sedation, decreased bowel movement and respiratory depression are limiting its use. so local anesthesia done with regional block methods provides good analgesia after surgery that decrease use of opioid analgesics. in this study we intend to compare subcostal TAP block with external oblique intercostal block
- Detailed Description
in our study, we include the patients who has diagnosed Gastric Cancer and going to open gastrectomy surgery. this surgery performing with initial upper umbilical median incision of abdomen and then removing part or all of the stomach organ, which is cause postoperative pain on all abdominal area and affect the patient's recovery and morbidity. perioperative pain management is also important part of recovery after surgery. intravenous morphine using is part of protocols in analgesics. lately opioid free analgesia is aimed because of opioids side effects such as sedation, respiratory depression and decrease in bowel movement affect patients' recovery and duration in hospital. in this way regional and local anesthetics methods are getting more interested in pain management. To ensure the analgesic effects of the upper umbilical median incision area we planned to perform External Oblique Intercostal (EOI) block and Subcostal Transversus Abdominis Plane (SCTAP) block. To get better results we performed both blocks with Ultrasound Guided Imaging and injected bilateral with 15-20 ml of diluted local anesthetics on each side before the surgery. We divide patients into two groups: Group 1: the patients who get SCTAP block and Group 2: the patients who get EOI block. After the general anesthesia and intubation of patient we clean the abdominal area within antiseptic to perform injection before the surgery is began. In Group 1, SCTAP Block is performing by USG probe positioned on the anterior abdominal wall immediately inferior to the costal margin and then needle advanced to 2 to 3 cm lateral to the aponeurosis of the external oblique muscles, internal oblique muscles, and transversus abdominis in the TAP. Saline 0.5mL was injected to determine the position of the transverse fascia and 15-20 ml local anesthetics injected both in right and left sides of abdomen. In Group 2, EOI block is performed by placing the US probe in paramedian sagittal orientation at the T6-7 level and visualizing the external oblique and intercostal muscles. Local anesthetics inject the under the external oblique muscle. After the surgery patient controlled analgesia (PCA) is given to patients if there will not enough analgesic management confirmed. Pain assessment will be evaluated with the visual pain scale at 2/6/12/24 hours after surgery completed.
