Conditions

Laparoscopic Cholecystectomy

Brief summary

Objective: Regional anesthesia techniques, such as peripheral nerve blocks, have a lower side effect profile and higher patient satisfaction compared to central blocks. With the introduction of Ultrasonography (USG), these techniques have become more commonly and reliably performed. The purpose of our study is to compare parameters such as intraoperative hemodynamics, postoperative analgesic requirement, and patient satisfaction between patients undergoing External Oblique Intercostal Plane Block (EOIB) with those who did not receive EOIB, which has few studies conducted on it.

Interventions

PROCEDUREExternal Oblique Intercostal Plane Block

After endotracheal intubation, a 22-gauge 100 mm long block needle will be inserted at the T6-T7 level under USG guidance and bilateral EOIB will be applied with 20 cc of 0.25% Bupivacaine on each side under the external oblique intercostal muscle (total 40ml bilaterally).

Design outcomes

Primary

MeasureTime frameDescription
Numeric Rating ScalePostoperative 30.second,2 hours, 6 hours,12 hours,24 hoursThey will be numbered from 1 to 10. If reporting a score on a scale, please include the unabbreviated scale title, the minimum and maximum values, and whether higher scores mean a better or worse outcome
Visual Analogue ScalePostoperative 30.second,2 hours, 6 hours,12 hours,24 hoursThe Visual Analogue Scale (VAS) is a subjective measure of pain. It consists of a 10cm line with two endpoints representing 'no pain' and 'worst pain imaginable'. Patients are asked to rate their pain by placing a mark on the line corresponding to their current level of pain. The distance along the line from the 'no pain' marker is then measured with a ruler giving a pain score out of 10.

Secondary

MeasureTime frameDescription
Postoperative vomiting and nauseaPostoperative 30.second,2 hours, 6 hours,12 hours,24 hoursPostoperative vomiting and nausea: yes or no
Opioid usePostoperative 24 hoursTramadol use
