The goal of this clinical trial is to find out whether WALANT is an alternative local anesthesia method that can increase patient comfort and reduce pain during CVC procedure, which is one of the invasive procedures to be performed especially in areas where bleeding control is difficult. The main questions it aims to answer are: * Can we offer an alternative local anesthesia method that can be used to treat patients who require CVC insertion with minimum pain and maximum comfort? * Can the WALANT technique reduce the risk of complications during CVC insertion? Participants were: randomized using a single-blind allocation method based on hospital file numbers: odd numbers received WALANT and even numbers received lidocaine. The WALANT solution was prepared according to the standard protocol and injected into a 3×3 cm target area 20 minutes before catheter insertion. CVCs were placed without ultrasound guidance in jugular, subclavian, or femoral veins by anatomical localization. Pain intensity was assessed using the Visual Analog Scale (VAS) before and after the procedure. In the control group, after marking the anatomical location, the vein where the procedure would be performed was identified by using a 10cc syringe, which was then passed through the skin and subcutaneous tissues using negative pressure. As the needle tip was slowly withdrawn, local anesthesia was induced with an average of 2-10ml lidocaine (1.5-2 mg/kg) applied to the designated 3x3cm area. The CVC was then placed according to routine procedures. Patient assessments were recorded using a visual analog scale before and after the procedure.

Comparison of the pain felt by patients after central venous catheter placement when local anesthesia is performed with Lidocaine and when it is performed with the Wide Awake Tourniquet-Free Local Anesthesia Technique (WALANT).
Timeframe: 45 minutes for each patient.
Comparison of Pain Experienced by Patients After Central Venous Catheter Insertion Procedure with Local Anesthesia with Lidocaine and the Wide-Awake Tourniquet-Free Local Anesthesia Technique (WALANT)
Timeframe: The time from the beginning of the CVC insertion process until the patient can describe the pain he/she feels is a maximum of 30 minutes. The study duration was 45 minutes per patient.
Pain felt after local anesthesia
Timeframe: The maximum time elapsed from the moment the patient was able to describe the pain felt after the local anesthesia procedure was 30 minutes.
