Brief summary
This study is to demonstrate the effectiveness of external oblique intercostal plane block, a new block method, in the treatment of postoperative pain occurring after laparoscopic cholecystectomy operations, which are frequently and widely performed today. It aims to add new applications to multimodal analgesia methods, which provide the greatest contribution to the early recovery process after surgery, and to contribute to the early recovery process by increasing patient satisfaction.
Detailed description
Postoperative pain is an acute pain that begins with surgical trauma and gradually decreases with tissue healing, and its elimination is important for ideal patient care after surgery. Postoperative pain; It varies depending on the type of surgery, the patient, and the need and type of analgesic in the intraoperative period. Although there have been new developments in recent years to relieve postoperative pain, studies have shown that 25% of patients can receive adequate postoperative pain treatment.The increase in thromboembolic, cardiac and respiratory complications caused by untreatable postoperative pain is one of the most important problems in operated patients. Laparoscopic cholecystectomy; It is one of the most frequently performed surgical procedures in adult patients, and different types of pain such as parietal, visceral and somatic (shoulder pain) can be observed due to tissue damage after laparoscopic cholecystectomy, postoperative pain, diaphragmatic irritation and residual pneumoperitoneum.Multimodal analgesia in laparoscopic cholecystectomies; It can be provided with combinations of regional anesthesia techniques, incision site local anesthetic applications, intravenous opioids, nonsteroidal anti-inflammatory drugs, paracetamol and preemptive analgesia methods. Regional anesthesia techniques have become more popular recently for the purpose of postoperative pain control, and regional anesthesia techniques in laparoscopic cholecystectomy such as epidural block, paravertebral block, transversus abdominis plan (TAP) block and External Oblique Intercostal Plan (EOIP) block, whose effectiveness has been shown by new studies. Includes methods. Oblique subcostal transversus abdominis plane (OSTAP) block is a regional anesthesia technique defined as a modified version of the TAP block used especially in upper abdominal surgeries such as Laparoscopic cholecystectomy.EOIP block is a new regional anesthesia technique that can provide analgesia in the postoperative period in upper abdominal abdominal surgery, which was demonstrated by anatomical studies in 2021. EOIP block, the spread of regional anesthesia to the lateral and anterior cutaneous branches of T6/7 and T10/11, the origin of the intercostal nerves, constitutes the mechanism of this technique and shows that Laparoscopic cholecystectomies can be effective in postoperative analgesia management. Regional anesthesia methods are frequently used in our clinic for patients undergoing upper abdominal surgery for analgesia. In this study, the investigators aimed to compare the EOIP block, OSTAP block and local anesthetic infiltration methods in laparoscopic cholecystectomy in terms of pain effectiveness in the postoperative period.
Interventions
PROCEDUREunilateral external oblique intercostal plane block group
USG guided external oblique intercostal plane block will perform unilateral with Bupivacaine 25 patient included and patients were observed for pain for 24 hours
PROCEDUREunilateral oblique subcostal transversus abdomınıs plane block group
USG guided oblique subcostal transversus abdomınıs plane block block will perform unilateral with Bupivacaine. 25 patient included and patients were observed for pain for 24 hours
PROCEDURELocal anesthetic infiltration group
Bupivacaine infiltration will be performed to trocar insertion sites. 25 patient included and patients were observed for pain for 24 hours
DRUGControl group
All patients were followed using a standardized postoperative analgesia protocol which includes tramadol patient controlled analgesia. Tramadol at a concentration of 5 mg/mL is included in our patient controlled analgesia protocol (total volume 100 mL.) patient controlled analgesias were set to no basal infusion and 10 mg bolus doses with a 20 min lock time 25 patient included and patients were observed for pain for 24 hours

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Amount of postoperative opioid use | 24 hours | Patient controlled analgesia (PCA) will provide with tramadol PCA. Total tramadol consumption will calculate and record till the postoperative 24th hours |
| Finding out which method is more effective according to the Numerical Rating Scale (0-10) | 24 hours | To find out which method provides more effective analgesia according to the Numeric Rating Scale patients followed for 24 hours. A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. 0 is no pain and 10 is the worst pain |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| postoperative nause and vomiting | 24 hours | The patient with nausea and vomiting will be recorded postoperative nausea and vomiting; will be evaluated as present or absent |
| postoperative shoulder pain | 24 hours | The patient with shoulder pain will be recorded postoperative shoulder pain; will be evaluated as present or absent |
