Table 2 Lung lavage time and volume of lavage fluid in both groups

From: Lung injury induced by different negative suction pressure in patients with pneumoconiosis undergoing whole lung lavage

Variables Group H (n = 13) Group L (n = 11) P
Right lung lavage time (min) 56.2 ± 15.3 65.0 ± 14.7 0.16
Right lung resuscitation time (min) 18.5 ± 5.2 17.7 ± 3.4 0.69
Left lung lavage time (min) 57.3 ± 15.4 62.7 ± 11.9 0.35
Left lung resuscitation time (min) 21.5 ± 4.7 20.0 ± 5.5 0.47
PIP (right lung lavage time) 26.0 ± 7.5 29.3 ± 8.3 0.40
PIP (left lung lavage time) 36.9 ± 5.7 35.4 ± 6.5 0.62
PIP (bilateral lung ventilation) 28.8 ± 7.4 27.5 ± 6.6 0.71
Right lung lavage volume (ml) 9625.0 ± 1060.7 8700.0 ± 1059.4 0.08
Right lung residual volume (ml) 550.0 ± 207.0 785.0 ± 221.2* 0.04
Left lung lavage volume (ml) 9500.0 ± 1069.0 8400.0 ± 1173.8 0.05
Left lung residual volume (ml) 425.0 ± 225.2 780.0 ± 278.1* 0.01
  1. Measurement data are expressed as means ± SD. Counting data were expressed as numbers and percentages. *was statistically significant compared with Group H, P < 0.05. Compared with group H, right and left lung residual volume were significantly (bold) increased in the group L (P = 0.04, P = 0.01)
  2. Group H, high negative suction pressure group; Group L, low negative suction pressure group
  3. PIP peak inspiratory pressure
