Filter by:The purpose of this research, which has been determined as non-significant risk by the central IRB overseeing the study, is to obtain information to help further develop a machine (a medical device) to measure the pressure around the brain from the outside (this pressure is called intracranial pressure or ICP). Monitoring and managing ICP is an important part of care for patients with conditions such as Traumatic Brain Injury (TBI). However, the current way of measuring ICP requires surgery to drill a hole into the skull, and therefore can introduce additional risks such as infections and pain. Recent research has shown it may be possible to measure ICP without needing surgery. This technology is in development, but large amounts of data is required to build these new devices. Through collecting a large database of information from patients who have both the routine surgical device and the research device applied to their head, the research team will work to develop and test an effective and potentially safer way of monitoring patient ICP.
Depending on the physiology of pregnancy, the risk of increased aspiration, difficult airway, increased oxygen consumption and reduced functional residual capacity, breathing problems make general anesthesia application risky. In obstetric operations, neuraxial anesthesia is preferred because of both maternal and maternal mortality and morbidity. Epidural area has decreased due to pregnancy physiology. Previous studies have shown that the blood given to the epidural area increases the intracranial pressure by compressing the dura mater.Optic nerve diameter measurements ultrasound guided is a non-invasive and reliable method for detecting intracranial pressure increase. In this study, aimed to compare the optic nerve sheath diameter before and after epidural anesthesia with USG.
