Brief Summary

**Brief Summary of the Study:**

**Objective:** Theobjective of this study is to collect digital biomarker (tissue oxygensaturation) measurements from patients using a near-infrared spectrophotometrydevice to explore early warning for surgical site infection.

**Methodology:** Crely has developed a sensor for continuous monitoring of tissuesaturation of Oxygen (StO2) that has higher potency in early prediction ofsurgical site infection. About 30 patients undergoing open abdominal surgeriesbetween the ages of 18 to 80 years would be enrolled in the study. The studyinvolves use of a gold standard device to measure tissue oximetry near site ofincision (Inspectra 650) used once before surgery (Day 0) followed by 2times/24 hours from POD 0-5. The investigational device from Crely,Non-Invasive, Low-Risk Experimental Medical Device continuously monitors StO2for 5 days post operation. The device will be carefully attached to the patientin the post operative recovery room only on extubation and under supervision bythe PI or Co-PI. In brief, the sensors are attached to the patient’s skin byadhesive, bilaterally 2 cm from the center of the incision line. The sensorsare subsequently connected to the data collector which is attached to thepatient’s chest to collect data continuously until day 5 post surgery. Data isstored through bluetooth in a pre-assigned laptop computer.Patients experiencestandard perioperative surgical procedures and medication of Medical Clinicincluding antibiotic prophylaxis, pain relief medication for muscle relaxationand anesthetized using Analgesics. Patient’s medical history would be obtainedand monitorinf of vitals on POD0-5, WBC count and CRP before surgery and on POD5would be carried out. Wound characteristics would be assessed daily after POD2,photographs taken and tissue oximetry readings recorded.

**Outcome of the study:** The ability of the sensor developed by Crely in early predictionof surgical site infection would be deciphered.

**Publication:** The findings from the study would be published in a peer reviewedjournal.
