Active clinical trials for "Compartment Syndromes"

Some robotic endoscopic surgeries require a steep Trendelenburg position and a carbon dioxide pneumoperitoneum. This minimally invasive approach has the advantages of less postoperative pain, shorter hospital stay and faster recovery. After prolonged operative time in a Trendelenburg position rare but significant complications are a cerebral oedema or a well leg compartment syndrome. Well leg compartment syndrome results from inadequate perfusion in the lower limbs and the perfusion pressure is decreased proportionally to the lower extremity elevation. The condition can lead to release of intracellular proteins and myoglobinuria, hyperpotassaemia and metabolic acidosis followed by cell necrosis. The risk for tissue damage increases after 4 hours in a Trendelenburg position. If not promptly diagnosed and treated, a compartment syndrome has devastating complications like permanent dysfunction, limb loss, renal failure or even death. There are no specific guidelines for diagnosis and for the timing of surgical decompression. Fasciotomy is a clinical decision. There is no universal agreement at which compartment pressure irreversible muscle damage occurs. The only objective diagnostic tool available is currently to measure the intramuscular pressure, however this is invasive, painful and may yield unreliable results. An intracompartment pressure of 0- 10mm Hg is the normal range. Near Infrared Spectroscopy (NIRS) monitors are validated and approved to measure cerebral and somatic tissue oxygenation below the sensors and may help detecting promptly a compartment syndrome. Therefore, the investigators designed the present study to detect a change in the tissue oxygenation in the lower legs during robotic assisted, laparoscopic surgery in the Trendelenburg position.

This study is a prospective, randomized trial. Our study aims to study the effects of perioperative patient education about compartment syndrome on patients' perception of their own pain, amount of opioid medication utilization, and rate of diagnosis of compartment syndrome.

The CAPSS Study is a retrospective and prospective, multi-center, single-arm post-market data collection study with an FDA cleared device. Physiologic data measurements will be collected from enrolled subjects using electronic health records and data streams via the Accuryn Monitoring System. Analysis of these data has the potential to be able to acutely guide resuscitation and monitor trends for emerging critical conditions.

The Accuryn Registry Study is an open-ended, global, multi-center, retrospective and prospective, single-arm data collection study with an FDA cleared device. The target population are cardiovascular surgery patients. Physiologic data measurements will be collected from enrolled subjects using electronic medical records and data streams via the Accuryn Monitoring System.

The purpose of this study is to define the reliability and accuracy of Near Infrared Spectroscopy (NIRS) in the detection of intra-compartmental tissue perfusion in injured and noninjured extremities over time. The investigators hypothesize that this technology, combined with vital signs, intracompartmental pressures and clinical examinations, will be useful in diagnosing acute compartment syndrome (ACS), monitoring patients at risk for ACS, and evaluating the adequacy of fasciotomy in patients treated for ACS.

The aim of the proposed study is to determine the incidence and prevalence of intra-abdominal hypertension and abdominal compartment syndrome in consecutive intensive care admissions using broad inclusion criteria.

Early detection of intra-abdominal hypertension is essential to the prevention of abdominal compartment syndrome and requires close surveillance of intra-abdominal hypertension in patients at increased risk. intra-abdominal hypertension measurements are often taken by the bedside nurse, and in some cases, initiation of serial intra-abdominal hypertension monitoring is prompted by critical care nurses.

Acute compartment syndrome (ACS) is a complication of lower leg trauma that occurs when the pressure inside the leg due to swelling exceeds the body's ability to provide blood to the muscle of the leg. This condition cuts off blood flow to the leg. Left untreated, the condition can result in devastating consequences including complete loss of function of the lower extremity or amputation. Near-infrared spectroscopy (NIRS)-based tissue perfusion monitors are a non-invasive means of continuously monitoring the amount of oxygen in the tissues of an injured extremity. The device utilizes harmless red light to detect the proportion of hemoglobin saturated with oxygen up to 3 cm below the skin surface. The purpose of this study will be to launch the first stages of validation of this device as a diagnostic tool for compartment syndrome, by observing this device in uninjured subjects.

Study on quantitative perfusion parameters acquired on MR imaging of patients with non-tumoral pathology of the musculoskeletal system.

Near infrared spectroscopy (NIRS) provides a non-invasive means of continuously monitoring tissue oxygenation, which may be useful for diagnosis of acute compartment syndrome (ACS). Placement of these sensor pads on the surface of the skin must be such that light penetrates the intended compartment without inadvertently obtaining measurements of an adjacent compartment. The objective of this study is to examine whether the NIRS measurements of each compartment truly represent the tissue perfusion of the intended compartment, as indicated by the predictable decrease in muscle oxygenation of a given compartment in response to muscle fatigue. The investigators hypothesize that the tissue oxygenation values of the stimulated compartment will significantly decrease following muscle stimulation, indicating that the intended muscle compartment was successfully isolated. Additionally, the investigators hypothesize that NIRS values of unstimulated muscle compartments will not change from baseline.
