Detaljeret beskrivelse

A total of 30 participants aged 18 or older, with a planned plastic surgical reconstructive flap operation, will be recruited in this investigation. The primary purpose is to investigate the ability of the SpectroCor Tissue Oxygenation Monitor and its accessory SpectroCor Sensor to observe and monitor peripheral tissue oxygenation perioperatively. The investigation is designed as an open, non-controlled observational study with the primary goal of assessing the devices' ability to monitor and observe tissue oxygenation and safety in routine operation, reflecting the real-world patient population and treatment scenarios. Therefore, no control group is needed in this investigation.

In this study, the SpectroCor Tissue Oxygenation Monitoring is used to observe flap viability during and after plastic surgical reconstruction. SpectroCor sensor is inserted into the reconstructed flap or into the subcutaneous tissue in the distal wound to observe and collect data on tissue oxygenation. During the procedure, the flap tissue undergoes an ischemic period during microsurgical anastomosis, followed by reperfusion upon release of the vascular clamp. During the reconstructive flap surgery, spectroscopic data of tissue oxygenation are collected and compared to the recorded tissue saturation levels and to occurring events, procedures, and clinical parameters.

Foranstaltningsbeskrivelse
Tidsramme
Observe changes in flap tissue oxygenation
Tidsramme: From sensor placement until sensor removal minutes before completion of surgery (intraoperative period, approximately 2-6 hours)

To observe the changes in flap tissue oxygenation (combined hemoglobin/myoglobin saturation, %) measured by the SpectroCor Monitoring System during the ischemia-reperfusion sequence of microvascular flap reconstruction.

Continuous spectroscopic measurement of combined hemoglobin and myoglobin oxygen saturation in the transferred flap tissue, recorded from a SpectroCor Sensor inserted into the flap, with a second sensor placed in subcutaneous tissue of the distal wound. Saturation values are time-stamped against intraoperative events affecting flap perfusion (pedicle division and flap detachment from the donor site, completion of the microvascular anastomosis, release of the vascular clamp and reperfusion, and any anastomotic revision) and compared with paired arterial and venous blood gas samples obtained at the beginning and at the end of the surgery.
From sensor placement until sensor removal minutes before completion of surgery (intraoperative period, approximately 2-6 hours)

Foranstaltningsbeskrivelse
Tidsramme
Incidence of adverse events, adverse device effects, and device deficiencies
Tidsramme: From sensor placement during the operation until discharge from hospital (up to 30 days)
Number and proportion of participants experiencing at least one adverse event (AE), adverse device effect (ADE), serious adverse event (SAE), serious adverse device effect (SADE), or unanticipated serious adverse device effect (USADE), and the number of device deficiencies (DD) recorded. Events are recorded from the time of sensor placement until discharge from hospital and assessed for causal relationship to the investigational device by the investigator. Anticipated device-related events include topical bleeding at the sensor attachment site, local tissue reaction associated with tissue glue fixation, and local infection at the insertion site.
From sensor placement during the operation until discharge from hospital (up to 30 days)
