Different Intra-abdominal Pressures & Optic Nerve Size

Status Completed

Clinical Trial Summary

In intensive care patients, high intraabdominal pressure is frequently encountered. Intra-abdominal pressure is often measured as high, especially after major abdominal surgery procedures. In recent years, various studies have reported that the increase in optic nerve diameter measured by ultrasound correlates with the level of intracranial pressure. Optic nerve diameter measurement with ultrasound is a non-invasive procedure. Intra-abdominal pressure measurements are also routinely performed in intensive care patients. In the measurement of abdominal pressure, the bladder catheter, which is already available in every patient who comes to intensive care, is used. In this study, the intra-abdominal pressure values present in the file of each patient undergoing major abdominal surgery who were taken to intensive care unit will be taken. Orbital USG will be performed on the 6th, 12th and 24th hours on admission to the intensive care unit to measure the diameter of the optic nerve, and the relationship between the intra-abdominal pressure value and optic nerve diameters will be investigated.

Clinical Trial Description

In intensive care patients, high intraabdominal pressure is frequently encountered. Intra-abdominal pressure is often measured as high, especially after major abdominal surgery procedures. This situation creates ischemia in the abdominal organs in the patient, decreases venous return as a result of inferior vena cava compression and leads to a decrease in cardiac output. In addition, intracranial pressure frequently increases as a result of the venous circulation being affected. In recent years, various studies have reported that the increase in optic nerve diameter measured by ultrasound correlates with the level of intracranial pressure. Optic nerve diameter measurement with ultrasound is a non-invasive procedure. Intra-abdominal pressure measurements are also routinely performed in intensive care patients. In the measurement of abdominal pressure, the bladder catheter, which is already available in every patient who comes to intensive care, is used. In this study, the intra-abdominal pressure values present in the file of each patient undergoing major abdominal surgery who were taken to intensive care unit will be taken.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
