NCT06036498

Brief Summary

The goal of this clinical trial is to test intracranial blood flow and cerebral oxygenisation changes in patients who have pneumoperitoneum in laparoscopic cholecystectomy procedure. The main questions aim to answer are:

  • How does pneumoperitoneum in laparoscopic cholecystectomy procedure changes blod flow in patients?
  • Are there any differences between Near-Red spectroscopy and transcranial doppler ultrasonography assesment? Participants will be diagnosed with using NIRS probes and Doppler ultrasonography probes if any changes in surgical procedure. Researchers will compare NIRS and TCD detection outcomes to see if there is any differences.

Outcome Measures

Primary Outcomes (2)

  • Detecting Cerebral Blood Flow Changes at Pneumoperitoneum Time via New Assessment Methods

    In this study, aimed at patients scheduled for laparoscopic cholecystectomy, Researchers intend to utilize transcranial doppler ultrasonography to detect changes in intracranial blood flow changes during the preoperative, intraoperative, and postoperative periods.

  • Detecting Cerebral Tissue Oxygenisation Changes at Pneumoperitoneum Time via New Assessment Methods

    In this study, aimed at patients scheduled for laparoscopic cholecystectomy, Researchers intend to utilize Near Infrared spectrophotometry methods to detect oxygenisation changes in cerebral hemispheres during the preoperative, intraoperative, and postoperative periods.
