Brief Summary

This study aims to determine the most effective and long-lasting pain relief method for post-operative analgesia in kidney donor and recipient patients in kidney transplantation programme with the least invasive and least drug administration.

For this reason, it is planned to perform Quadratus lumborum plane block (QLB) in a group of patients who will be kidney donors and kidney recipients in kidney transplantation and who meet the American Society of Anesthesiologists (ASA) Physical Status Classification System 1-3 risk classification between the ages of 18-70 years, and to administer intravenous pain medication without block in another group. It is planned to include at least 84 patients in the Quadratus lumborum plan block (QLB) and Intravenous Analgesia group (IVA) without gender discrimination.

Postoperative Sedation-Agitation assessment and NRS (numeric pain scale) at 1st hour, 2nd, 6th, 12th and 24th hours, as well as possible side effects such as nausea, vomiting, shoulder pain, respiratory depression, bradycardia and hypotension, total amount of opioid analgesics consumed within 24 hours and duration of hospital stay will be observed and recorded.

Detailed Description

Plane block ultrasound-guided intra-abdominal injection into the appropriate anatomical area

* the injection will be administered immediately after general anaesthesia and intubation of the patient

* to monitor compliance with the intervention The medical files and laboratory blood tests of the patients will be examined to determine whether there are any contraindications to the intervention (patients will be excluded in case of bleeding diathesis such as intra-abdominal fluid accumulation, cystic formation, International Normalized Ratio (INR) \> 2 or thrombocytopenia).

Blood pressure and heart rate values of the patient and the amount of fentanyl consumed will be recorded throughout the surgery.

The level of sedation-agitation will be evaluated during extubation at the end of surgery.

In the postoperative period, blood pressure, heart rate, pain scoring and the amount of opioid analgesic consumed will be recorded by the anaesthesiologist in the general surgery organ transplant unit and the general surgery specialist and nurses in the organ transplant service at the 1st, 2nd, 6th, 12th, and 24th hours.

The patient's satisfaction level will be evaluated and recorded 24 hours after the operation.

Primary Outcome Measures
NameTimeMethod
Assessment of pain (NRS) levelpostoperative 1st, 2nd, 6th, 12th, 24th hours

The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable"

Secondary Outcome Measures
NameTimeMethod
Sedation- agitation levelWill be assessed from immediately after extubation until transfer from the recovery room to the ward.

The Riker Sedation Agitation Scale (RSAS): identifies seven levels of sedation and agitation, which range from dangerous agitation to deep sedation, with a thorough description of patient behavior.

Riker sedation-agitation Scale:1- Unarousable, 2 -Very Sedated, 3- Sedated, 4 Calm and Cooperative, 5 -Agitated, 6 -Very Agitated, 7 -Dangerous Agitation

Duration of first analgesic requirementDuring the 24 hours postoperative period

Time in minutes from the patient's extubation to the first analgesic requirement

Blood pressure measurementIt will be recorded 10 minutes before induction of anesthesia and every 15 minutes after intubation until the end of the operation.

Systolic, diastolic and mean arterial pressure measurements will be recorded by invasive arterial monitoring.

Measurement of heart rateIt will be recorded 10 minutes before induction of anesthesia and every 15 minutes after intubation until the end of the operation.

The number of heart beats per minute obtained by electrocardiographic monitoring

Amount of fentanyl consumed during the operationDuring surgery

Micrograms of fentanyl consumed during surgery

Patient satisfaction assessmentAt the end of 24 hours postoperatively

Patients' satisfaction with the quality of pain management will be assessed at 24 hours postoperatively using the following scale:

1 = very dissatisfied; 2 = quite dissatisfied; 3 = moderate; 4 = quite satisfied; 5 = very satisfied.

Nausea-vomitingDuring the 24 hours postoperative period

Questioning about the presence/absence of nausea and/or vomiting in the postoperative period

Length of hospital stayIt is assessed for up to 12 months from the date of surgery to the date of the first documented progression or the date of death from any cause, whichever comes first

Days of hospitalisation after the operation

Total postoperative tramadol consumptionWithin 24 hours postoperatively

milligrams
