## Brief Summary

Present study aimed to evaluate the accuracy of Masimo Radical 7 to monitor hemoglobin concentrations through compared with laboratory measurement during major hepatic surgery, and to determine the source of discordance between two methods.

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 75 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* adult patients

```

## Primary Outcomes

- **Hemoglobin measurement using the Masimo device** _(time frame: 0.5h after skin incision)_

## Secondary Outcomes
