Analgesia, Obesity, Postoperative Pain
Conditions
Brief summary
The external oblique intercostal (EOI) plane block is a novel approach upper abdominal wall analgesia. The EOI plane block can provide dermatomal sensory blockade of T6-T10 at the anterior axillary line and T6-T9 at the midline. It may be used for postoperative analgesia in obese patients because it is superficial and rapidly identifiable and performed in the supine position. the aim of this study is to investigate the postoperative analgesic efficacy of external oblique intercostal plane block in obese patients undergoing laparoscopic sleeve gastrectomy. Researchers will compare the external oblique intercostal plane block group with control group to see if the EOI plane block is effective for postoperative analgesia in patients undergoing sleeve gastrectomy.
Detailed description
Patients scheduled for elective laparoscopic sleeve gastrectomy will be separated into 2 groups: Control Group and External Oblique Intercostal Plane Block Group. Patients in Control Group will be received patient controlled analgesia with morphine for postoperative analgesia. Patients in External Oblique Intercostal Plane Block Group will be performed bilateral External Oblique Intercostal Plane Block before the surgery and received patient controlled analgesia with morphine for postoperative analgesia. Morphine consumption for first postoperative 24 hours, visual analog scale scores, time to need for first rescue analgesia, amount of rescue analgesic drug, incidence of postoperative nausea and vomiting will be recorded.
Interventions
OTHERIntravenous morphine patient control device

Primary
| Measure | Time frame | Description |
|---|---|---|
| Morphine consumption | Postoperative 24 hours | The amount of morphine required by the patient and given by the device will be recorded for the first 24 hours. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative visual analog scale scores | Postoperative 24 hours | Postoperative pain will be assessed using a visual analog scale (VAS) (from 0 = no pain to 10 = maximum possible pain) for the first 24 hours. |
| Time to first rescue analgesic | postoperative 24 hours | The time for administration of first rescue analgesic will be recorded. |
| Rescue analgesic drug consumption | postoperative 24 hours | The amount of rescue analgesic in mg required by the patient will be recorded for the first 24 hours. |
| Incidence of postoperative nausea and vomiting | postoperative 24 hours | Number of patients developing postoperative nausea and vomiting will be recorded for the first 24 hours |
