About this study
Official title: TAPA Block Versus Conventional Analgesia Methods on Cognitive Functions and Postoperative Opioid Consumption in Major Abdominal Surgery
It was planned to compare the opioid consumption and cognitive functions in the postoperative period of patients who received TAPA block for postoperative analgesia and patients who did not prefer the block and who preferred intravenous patient-controlled analgesia (PCA) with opioids. Both the surgery applied and the drugs used in anesthesia can cause changes in cognitive functions by affecting the inflammatory process. It is thought that if the patients' pain can be relieved sufficiently in the postoperative period with TAPA block, the consumption of opioids used will be less and their cognitive functions will be less affected.
Read the detailed description
Postoperative pain management after major surgical operations is a very important issue. Features such as waking up without pain, early recovery from anesthesia, not suppressing respiration by the drugs used for postoperative pain treatment, not delaying recovery from anesthesia, not having unwanted side effects, and not delaying discharge from the intensive care unit are the desired features of postoperative pain management. A wide variety of drug therapy modalities are available for this purpose. However, peripheral nerve blocks are widely used to minimize undesirable effects of drug therapy. TAP block (trans abdominal plane block) has been used for this purpose since ancient times. TAPA block (thoracoabdominal block with perichondral approach) is a newly developed plane block and was developed to obtain higher level block with a single injection. In this study, we planned to compare the recovery times from anesthesia, postoperative pain scores, opioid consumption, and cognitive functions of patients who underwent TAPA block for postoperative pain treatment and patients who were not preferred to TAPA block and were planned for pain treatment with conventional methods, whether these treatments affected or not.
Neuropsychological dysfunction is a frequently encountered condition after surgery. Postoperative cognitive dysfunction can affect various cognitive functions such as attention, memory, and information processing speed. The most notable symptoms are memory deficits and decreased ability to cope with intellectual difficulties. It has been stated that postoperative cognitive dysfunction depends on advanced age, duration of anesthesia, development of complications, pre-existing cognitive disorders, and education level.
In a study, it was reported that the incidence of postoperative cognitive dysfunction in patients aged around 60 years who underwent major noncardiac surgery was 25.8% after 1 week and 9.9% after 3 months.
In the literature, it has been mentioned that inflammatory processes that occur as a result of surgical trauma and subsequent complications play a role in cognitive dysfunction. Normal cognitive functions can be maintained in low-level inflammatory processes, while very high-level proinflammatory factors can significantly affect cognitive functions.
Traditional lateral TAP block is performed on the midaxillary line between the iliac crest and subcostal. With this approach, with cadaveric dye injection, T11 was shown to be maintained and T12 was maintained 100% time, L1 93% time and T10 50% time. The lateral TAP block reached a dermatome high enough to benefit the patient after open cholecystectomy.
The TAPA block is performed at the rib margin where the 9th and 10th ribs meet. A linear transducer is placed at the costochondral angle in the sagittal plane. It is carried out by injecting 20 ml of drug between the upper and lower surface of the chondrium. The authors state that TAPA block provides analgesia to T5-T12. They hypothesize that the TAPA block numbs both the lateral cutaneous branch and the anterior region.
Although the standardized mini-mental test is not a definitive diagnostic test, it is used by clinicians as an auxiliary test to measure the degree of cognitive deterioration of patients.
We planned this study to compare the recovery times from anesthesia, postoperative pain scores, opioid consumption, and cognitive functions of patients who underwent TAPA block for postoperative pain management and patients who were not preferred TAPA block and were planned for pain treatment with conventional methods, whether these treatments were affected or not.

Group I: TAPA blockProcedure or surgery
Also called thoracoabdominal block perichondral appearance
Postoperative analgesia will be provided with peripheral nerve block (TAPA)
Group II: IV MorphineProcedure or surgery

Postoperative analgesia will be provided with opioids
| Study group | Role | What they receive |
|---|---|---|
| Group I (n=45, TAPA) | The patients who received TAPA block for postoperative analgesia are named as a Group I ( n=45). The TAPA block is performed at the rib margin where the 9th and 10th ribs meet. A linear transducer is placed at the costochondral angle in the sagittal plane. It is carried out by injecting 20 ml of Bupivacaine %0.200 between the upper and lower surface of the chondrium. All patients receive IV PCA with morphine 0.5 mg/ml. Receives: Procedure: Group I: TAPA block | |
| Group II (n=45, IV opioid) | The patients who did not prefer the block and preferred intravenous patient-controlled analgesia (PCA) are named as Group II (n=45). IV PCA is prepared with morphine 0.5 mg/ml. Receives: Procedure: Group II: IV Morphine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cognitive functions
Cognitive functions will be evaluated with Mini-mental test in each patient on postoperative day 3.
Measured: postoperative day 3
Secondary outcomes (2)
postoperative pain scores
Postoperative pain scores will be recorded. The evaluation will be made with Visual Analogue Scale (VAS) score in the 1st, 2nd, 6th, 12th and 24th hours postoperatively.
VAS score is determined via using a ruler, measuring the distance on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-10.
Measured: 24 hours postoperatively
Postoperative morphine consumption within 24 hours postoperatively
Total morphine consumption in 24 hours postoperatively will be recorded via Patient Controlled Analgesi (PCA) device.
Measured: 24 hours postoperatively

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Both the surgery applied and the drugs used in anesthesia can cause changes in cognitive functions by affecting the inflammatory process.

Questions about this trial
What is this clinical trial studying?
An observational study of Pain, Postoperative and Cognition, run by Dr Abdurrahman Yurtaslan Ankara Oncology 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 4 inclusion and 11 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 2 Mar 2023. 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.
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?
Cognitive functions (time frame: postoperative day 3). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05215691, which also lists 7 linked publications.
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 2 Mar 2023; AzTrials last refreshed its copy on 8 Nov 2026.
