Objective: To observe the effect of acute lung injury after abdominal surgical operations treated with herbs activating blood circulation and dispersing stasis.Methods: Forty-four patients complication with acute lung injury after abdominal operation were analyze with multiple clinical and laboratory parameters and were treated early with herbs activating blood circulation and dispersing stasis.Results: After 2 days of medication

arterial oxygen saturation (SaO2) and partial pressure of oxygen in artery (PaO2) markedly improved

with significant difference as compared with those before medication (P<0.01). After continous medication for 4 days

SaO2

PaO2 and chest X-ray as well as synthetic physiologic parameters obviously improved

prostaglandin F1a

thromboxane B2 (TXB2)

C-reactive protein (CRP)

erythrocyte C3b were very significantly different from those medication (P<0.01)

the synthetic physiological parameters returned generally to normal. After 5 days of herbal medication

all parameters resumed normal with satisfactory physiologic criteria.Conclusions: Early application of herbs activating blood circulation and dispersing stasis could obviously improve hypoxemia and the lung lesions

and consequently the general condition of the patient.
