Filter by:This is a prospective, single arm, open, single centre clinical investigation designed to examine the feasibility and safety of the IscAlert™ device in patients scheduled for limb (arm/leg) surgery with tourniquet. IscAlert is measuring carbon dioxide in muscular and subcutaneous tissue. IscAlert is inserted into normal muscle and subcutaneous tissue in ischemic (operated limb with a tourniquet) and non-ischemic limb (non-operated limb).After the tourniquet is inflated, ischemia develops in the muscles and subcutaneous tissue. This will result in an increase in carbon dioxide, which will be detected by the sensor on the operated extremity, while the sensor on the non-operated will show normal values. After releasing the tourniquet cuff, the muscle will be reperfused and the carbon dioxide level is expected to decrease into normal levels. 50 number of patients will be enrolled to undergo the procedures. The IscAlert will be removed from the patient before the patient is discharged from the operating room, but in 25 of the patients, IscAlert™ will be inserted for 72 hours in the operated extremity after the end of surgery. After this, the sensors are removed.250 Devices is planned to be used in this clinical study.
This study is being conducted to determine whether providers who have access to their patients' acoustic intestinal rate score as calculated by an abdominal acoustic sensor that continuously monitors bowel sounds (AbStats) will be more likely to advance their patients' diets to a solid diet sooner than those who do not have access to this rate. AbStats calculates intestinal rates by using two small sensors placed on a patient's abdomen to measure and analyze their abdominal sounds. Patients will be asked to wear a sensor every morning for 20 minutes while they are fasting daily during their inpatient visit. The sensor will measure the sounds within their abdomen. This data will be interpreted by the AbStats device, which will provide an intestinal rate measurement based on the sounds recorded by the sensors. This intestinal rate will be provided to the patient's treating physician together with other vital signs. The doctor, at his/her discretion, may choose to use this information to make decisions about the patient's feeding status.
