Comparative StudyBlood pressure and free flap oxygenation in head and neck cancer patients.
This study suggests that although oxygen partial pressure in tissue (p(ti)O(2)) measurement is a feasible method for continuous postoperative monitoring of free flaps, low correlation between blood pressure (BP) and p(ti)O(2) might predict compromised overall outcome. Thus, it is of utmost importance to keep the BP optimal for adequate perfusion of re-anastomosed tissue transfers. ⋯ The correlation coefficient between p(ti)O(2) and BP was relatively high in all patients with uneventful flap survival (r (mean) = 0.63, n = 5). In flaps with haemodynamic problems or compromised flap vitality the correlation appeared low (r(mean) = -0.02, n = 5).
