Table 4. Hemostatic Likert score assessment of SDR firings on pulmonary arteries and pulmonary veins.
| Assessment and hemostatic score | SDR firings on arteries (n=145) | SDR firings on veins (n=157) | Total SDR firings (n=302) |
|---|---|---|---|
| Acceptable | 143 (98.6) | 156 (99.4) | 299 (99.0) |
| 1. No bleeding at tissue site after initial blotting of staple-line | 127 (88.8) | 148 (94.9) | 275 (92.0) |
| 2. Blood oozing at tissue site; stops prior to 15 seconds; no intervention needed | 4 (2.8) | 0 (0.0) | 4 (1.3) |
| 3. Blood oozing, still progressive after 15 sec., no intervention needed | 4 (2.8) | 0 (0.0) | 4 (1.3) |
| With Likert scores (1–3) | 135 (94.4) | 148 (94.9) | 283 (94.6) |
| Likert scores not recorded† | 8 (5.6) | 8 (5.1) | 16 (5.4) |
| Not acceptable | 2 (1.4) | 1 (0.6) | 3 (1.0) |
| 4. Blood oozing at tissue site, mild intervention (i.e., cautery) | 2 (100.0) | 1 (100.0) | 3 (100.0) |
| 5. Significant bleeding requiring intervention such as extensive coagulation or ligation with clips | 0 (0.0) | 0 (0.0) | 0 (0.0) |
| With Likert scores [4, 5] | 2 (100.0) | 1 (100.0) | 3 (100.0) |
| Likert scores not recorded† | 0 | 0 | 0 |
Data are presented as n (%). †, there were sixteen firings that did not require hemostatic intervention based on surgeon review of their operative notes, however a Likert scale score was not assigned to these firings by the surgeons. For this reason, all sixteen firings are grouped with scores 1–3 and considered acceptable staple-lines not requiring intervention. SDR, Signia™ Small Diameter Reloads.
