Aneurysmal Subarachnoid Hemorrhage Treatment Based on Intracranial Pressure Monitoring

ASTIM
Start date: April 1, 2024

ASTIM is a multicenter, prospective, randomised, blinded end-point assessed trial, to investigate the efficacy and safety of treatment based on intracranial pressure monitoring in improving the prognosis of patients with aneurysmal subarachnoid hemorrhage.

NCT ID: NCT06209034 Recruiting - Clinical trials for Intracranial Pressure Increase

Intraoperative Optic Nerve Sheath Diameter Changes After Laparoscopic Surgery

Start date: December 30, 2023
Phase: N/A
Study type: Interventional

Laparoscopic surgery is a widely used alternative to open surgery; Advantages include reduced bleeding and pain intensity, shorter hospital stay, and improved cosmetic results. Laparoscopic surgery involves the creation of a carbon dioxide (CO2) pneumoperitoneum to facilitate a clear surgical view, which can result in increased intracranial pressure (ICP). Ultrasonographic measurement of optic nerve sheath diameter (ONSD) is a simple, non-invasive, yet reliable technique for ICP assessment.Ultrasonographic assessment of optic nerve sheath diameter (ONSD) has been proposed as a non-invasive measurement of intracranial pressure.

NCT ID: NCT06048900 Completed - Clinical trials for Intracranial Pressure Increase

Evaluation of the Effect of Trendelenburg Position Duration on Intracranial Pressure

Start date: March 10, 2021
Phase: N/A
Study type: Interventional

The Lloyd Davies position is a position used in laparoscopic hysterectomies where the head is lowered 45 degrees and the legs are bent from the knee area.It is a version of the Trendelenburg position. Both this position and for laparoscopic surgery carbon dioxide (CO2) gas given into the abdomen, causes problems for the patient. Increased abdominal and thoracic pressure impairs venous return and increases intracranial pressure. Optic nerve sheath diameter can be measured by placing an ultrasound probe over the eye. It is possible to follow up the increase in intracranial pressure with this diameter measurement. In this study, it was planned to measure the optic nerve sheath diameter by ultrasound in patients who will undergo laparoscopic hysterectomy. It is aimed to observe the changes in the increase in intracranial pressure as the time lengthens with the measurements to be made at certain intervals during the operation. Secondary aim is to determine whether there is a cut-off value where the intracranial pressure starts to increase.

NCT ID: NCT05931991 Recruiting - Clinical trials for Intracranial Pressure Increase

Intra-operative Evaluation of the External Ventricular Drain Catheter Position With Structured Light for Patients (Bullseye EVD)

Start date: July 7, 2023
Phase:
Study type: Observational [Patient Registry]

The placement of external ventricular drainage (EVD) is a life-saving procedure used to relieve high pressures in the brain. Often performed at the bedside, a small tube (catheter) is inserted into one ventricle of the brain to drain cerebrospinal fluid and release the pressure build up. In standard practice, EVDs are placed freehand and initial catheter malpositioning occurs in up to ~60% of procedures. Currently, there are no adequate means to verify the position of the catheter before insertion which is a significant impediment to ensure accurate positioning. This non-interventional study aims to validate a novel technology, Bullseye EVD, for verifying the position of the EVD catheter during these emergency procedures.

NCT ID: NCT05731765 Active, not recruiting - Clinical trials for Intracranial Pressure Increase

SVP Detection Using Machine Learning

SVP-ML
Start date: March 1, 2023
Phase:
Study type: Observational

This diagnostic study will use 410 retrospectively captured fundal videos to develop ML systems that detect SVPs and quantify ICP. The ground truth will be generated from the annotations of two independent, masked clinicians, with arbitration by an ophthalmology consultant in cases of disagreement.

NCT ID: NCT05668208 Completed - Clinical trials for Intracranial Pressure Increase

Do Extraperitoneal Laparoscopic Surgeries Increase Intracranial Pressure?

Start date: January 6, 2023
Phase: N/A
Study type: Interventional

When the literature is examined, it has been reported in many studies that intracranial pressure increases due to laparoscopic procedures performed in the intraperitoneal area. The mechanism of increased intracranial pressure (ICP) associated with insufflation is most likely due to impaired venous drainage of the lumbar venous plexus at increased intra-abdominal pressure. Changes in ICP can be monitored by ultrasonographic measurement of optic nerve sheath diameter (ONSD), which is a generally accepted simple, reliable and non-invasive ICP measurement technique. In meta-analyses conducted on this subject, it has been revealed that ICP elevation during laparoscopy can be observed with a significant increase in ONSD in the early (0 30 minutes) and late (30-120 minutes) periods during carbondioxid (CO2) pneumoperitoneum. However, the effect of laparoscopic procedures performed in the extraperitoneal area on the central nervous system is not clear. There is not found any study in the literature comparing laparoscopic procedures, especially performed extraperitoneally and transperitoneally, and their effects on intracranial pressure. The aim of the study compare to laparoscopic cholecystectomy performed in the transperitoneal area and (totally extra-peritoneal) TEP inguinal hernia repair performed in the extraperitoneal area in terms of intracranial pressure relationship.

NCT ID: NCT05609071 Active, not recruiting - Brain Diseases Clinical Trials

Technology of Intracranial Pressure Estimation by Single-Channel EEG in Brain Disease

Start date: March 22, 2022
Phase:
Study type: Observational

If intracranial pressure can be measured non-invasively using single-channel EEG, clinicians will be able to easily monitor changes in intracranial pressure in patients with brain diseases in the clinical setting. Therefore, a more efficient treatment plan can be established and the prognosis of patients with brain disease can be expected to improve in the long term.

NCT ID: NCT05499754 Completed - Clinical trials for Intracranial Pressure Increase

Effect of Different Supralottic Airway Devicess on Optic Nerve Sheath Diameter

Start date: July 1, 2019
Phase:
Study type: Observational

Direct laryngoscopy and tracheal intubation are associated with increases in intraocular pressure (IOP), intracranial pressure (ICP), heart rate (HR), and blood pressure. The use of supraglottic airway devices (SADs) are known to be beneficial in overcoming the disadvantages of laryngoscopy and tracheal intubation, especially ocular and pressure stress responses. In recent years, it has been reported that ultrasonographic measurement of optic nerve sheath diameter (ONSD) can be used in the diagnosis of increased ICP. The aim of our study is to compare the effects of Proseal laryngeal mask airway (pLMA), Suprem laryngeal mask airway (sLMA) and I-gel on hemodynamic response and ONSD during insertion in adult patients.

NCT ID: NCT05445271 Not yet recruiting - Clinical trials for Intubation Complication

Optic Nerve Sheath Diameter in Pediatric Patients

Start date: July 1, 2022
Phase: N/A
Study type: Interventional

Endotracheal intubation and laryngeal mask are generally applied to secure the airway during general anesthesia. There is a widespread opinion among anesthesiologists that endotracheal intubation increases intracranial pressure. Since there were no non-invasive methods measuring intracranial pressure in the past, adequate studies on this subject could not be done. With this measurement, we aimed to show whether ETT or LMA applications have effects on intracranial pressure.

NCT ID: NCT05434975 Recruiting - Clinical trials for Brachial Plexus Block

The Effect of Interscalene Block on Intracranial Pressure

Start date: February 25, 2022
Phase: N/A
Study type: Interventional

The study aims to show the effects of interscalene brachial plexus (ISBP) block on intracranial pressure by measuring optic nerve sheath diameter (ONSD) and internal vein collapsibility index (IJV-CI).
