Table 3. Impact of postoperative complications on the microcirculation.
| SO2 day 0 | Hb day 0 | Flow day 0 | Velocity day 0 | SO2 day 7 | Hb day 7 | Flow day 7 | Velocity day 7 | |
|---|---|---|---|---|---|---|---|---|
| Necrosis | −0.158 (0.102) | −0.177 (0.068) | 0.026 (0.788) | 0.012 (0.902) | −0.326 (0.003) | −0.227 (0.038) | −0.437 (<0.0001) | −0.431 (<0.0001) |
| Haematoma | 0.031 (0.782) | 0.086 (0.435) | −0.014 (0.896) | −0.100 (0.366) |
Pearson’s correlation was used for the statistical analysis. The Pearson coefficient, r, and the two-tailed P values (in brackets) are provided. Abbreviations: (Day 0) the day of the operation after the flap was raised, (Day 7) postoperative day 7, (SO2) oxygen saturation, (Hb) haemoglobin level, (Flow) blood flow, (Velocity) blood flow velocity. The rates of both necrosis and haematoma were assessed on day 7. Not all comparisons made logical sense, and statistical tests were therefore not performed in these cases (empty boxes). Statistically significant differences (P < 0.05) are marked in bold.
