Table 3 Comparison of bleeding incidence and hemodynamic changes induced by NGI

From: A preinstalled nasopharyngeal airway in the right nasal passageway to facilitate nasogastric intubation in anesthetized and intubated patients: a prospective randomized controlled trial

Outcomes

Group NPAa (n = 53)

Group Ob (n = 55)

Statistical test results

Bleeding, % (n/N)

5.7 (3/53)

12.7 (7/55)

P = 0.321 (Fisher exact test)

ARR = 7.1, 95% CI = − 3.7 to 17.9

RRR = 55.5, 95% CI = − 63.0 to 87.9

ΔHR (BPM), mean (SD)

7.4 (9.6)

7.7 (11.3)

P = 0.884 (Student t test)

Mean difference = − 0.3, 95% CI = − 4.3 to 3.7

ΔMBP (mmHg), mean (SD)

12.6 (12)

12.0 (12.9)

P = 0.813 (Student t test)

Mean difference = 0.6, 95% CI = − 4.2 to 5.3
