Trial summary

The most important determinant of the recovery in abdominal surgery is postoperative pain. Postoperative pain can be explained by 2 pathways connected to the peritoneum; The first is the parietal peritoneum, whose innervation is very rich and the other is the visceral peritoneum which is stimulated at the vagus level.

About this study

The most important determinant of the recovery in abdominal surgery is postoperative pain. Postoperative pain can be explained by 2 pathways connected to the peritoneum; The first is the parietal peritoneum, whose innervation is very rich and the other is the visceral peritoneum which is stimulated at the vagus level. Since 1950, they have been injecting local anesthetic for post-surgery pain. inflammation and peritoneal irritation are the most important factors of pain when acute appendicitis is diagnosed. . This increases the length of hospital stay and increases the cost of pain relief, and reduces patient satisfaction. The aim of this study is to evaluate the application of Transversus Abdominis Plane Block . local anesthetic injection to the port sites, intraperitoneal periappendiceal local anesthetic injection is compared with the control group without any local anesthetic application to investigate which group has more analgesic effectiveness and thus reduce the amount of analgesics needed postoperatively, hospitalization Shortening the duration of the patient and taking the patient comfort to the next level.

Read the detailed description

Laparoscopic Appendectomy procedure will be performed in patients over 18 years of age who are hospitalized from the emergency department for acute appendicitis. 4 patient group will be established. The number of samples determined for Power: 0.80 and alpha: 0.05 was determined as minimum n: 28 for each group. Therefore, the groups will be determined to include 28 patients. In our clinic, local anesthetic injection to the trocar areas is routinely performed in laparoscopic appendectomy operations. After endotracheal intubation at the beginning of the operation, after appropriate skin staining and sterile dressing Transversus abdominis plane block (10 cc / 10 cc, 0.5% bupivacaine to the right and left transversus abdominis muscle regions) will be applied. local anesthetic injection to the pre-incision trocar sites (8 cc instead of infraumbilical trocar, 6 cc instead of the other 2 trocar 20 cc 0.5% bupivacaine solution will be applied), following intraperitoneal direct visualization of the appendiceal region - local anesthetic spraying into the periappendiceal area(1: 1 diluted with 20 cc saline, 20 cc 0.5% bupivacaine solution total 40 cc spraying ) will be applied. The fourth group will be the control group and any of these methods will not be applied, operation time and peroperative complications (appendiceal perforation etc.) will be recorded.Paracetamol 1 g + 1 mg / kg tramadol IV will be applied to all four groups as standard before extubation. Visual analogue scale (VAS) will be applied to all patients in the postoperative period. If VAS> 3 is still present, a dose of 1 mg / kg tramadol will be administered. Tenoxicam 1x1 IV will be applied to the patients on the 12th hour. All patients were postoperative; 1,2,4,6,12,24. VAS scores , patient satisfaction (0: never satisfied, 5: very satisfied) will be recorded. The group of patients will be determined according to the order of surgery. Pain scores of the patients will be performed by a physician who is not in the operation who does not know which group is taken. The patients included in the group will not be known to the patient by the pain scoring system and the study will be done as double blind. Patients will be randomized with this method.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. compare of local anesthetic applying methods for postoperative pain relief by VAS (Visual Analog Scala)

    pain scores of the participants will be followed at postoperative 1,2,4,6,12,24 hour (up to 24 hours).

    (VAS: from 0 to 10, 0 = no pain, 10 = the worst pain) The higher score idicates the worse outcome.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bupivacaine in people with Postoperative Pain, run by Fatih Sultan Mehmet Training and Research Hospital at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

compare of local anesthetic applying methods for postoperative pain relief by VAS (Visual Analog Scala) (time frame: 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Mar 2021.
