External Oblique Intercostal Plane Block for Laparoscopic Sleeve Gastrectomy

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.

About this study

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.

External Oblique Intercostal Plane Block

Other

External oblique intercostal plane block will be administered before the surgery.

Primary outcomes

  1. Morphine consumption

    Time frame: 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 outcomes

  1. Postoperative visual analog scale scores

    Time frame: 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.

  2. Time to first rescue analgesic

    Time frame: postoperative 24 hours

    The time for administration of first rescue analgesic will be recorded.

  3. Rescue analgesic drug consumption

    Time frame: postoperative 24 hours

    The amount of rescue analgesic in mg required by the patient will be recorded for the first 24 hours.

  4. Incidence of postoperative nausea and vomiting

    Time frame: postoperative 24 hours

    Number of patients developing postoperative nausea and vomiting will be recorded for the first 24 hours
