Objective To explore the feasibility to use pain scale and arterial oxygen partial pressure(PaO2)as screening internal fixation indications for patients with multiple rib fractures. Methods Clinical data of 48 patients with multiple rib fractures who were admitted to Shanghai Pudong Hospital from September 2010 to February 2013 were retrospectively analyzed. Visual analogue scale (VAS) was used for pain assessment. Twenty-four patients whose VAS was greater than or equal to 6 and PaO2 was less than 60 mm Hg 3 days after injury were chosen as the experimental group, including 16 males and 8 females with their age of 49.29±15.73 years. Another 24 patients whose VAS was less than or equal to 5 and PaO2 was greater than 60 mm Hg 3 days after injury were chosen as the control group, including 19 males and 5 females with their age of 48.63±13.49 years. Patients in both groups received rib internal fixation with steel plates. Three days and 1 week after surgery respectively, VAS and PaO2 were compared between the 2 groups. Results In the experimental group, VAS 3 days after surgery was significantly lower than preoperative VAS (4.09±0.93 vs. 8.21±1.18, P < 0.05), and VAS 1 week after surgery was significantly lower than preoperative VAS (3.20±0.98 vs. 8.21±1.18, P < 0.05). In the control group, there was no statistical difference between VAS 3 days after surgery and preoperative VAS (P > 0.05), and there was no statistical difference between VAS 1 week after surgery and preoperative VAS (P > 0.05). Three days after surgery, PaO2 of the experimental group was significantly higher than preoperative PaO2 (61.00±3.47 mm Hg vs. 53.00±3.97 mm Hg, P < 0.05). There was no statistical difference between PaO2 3 days after surgery and preoperative PaO2 in the control group (66.71±5.15 mm Hg vs. 66.00±5.00 mm Hg, P > 0.05). Three days after surgery, pneumonia occurred in 4 patients in the experimental group and 2 patients in the control group (χ2=0.762, P > 0.05). Three days after surgery, pain scale reduction of the experimental group was significantly higher than that of the control group (4.13±1.45 vs. 0.00±0.42, P < 0.05). One week after surgery, pain scale reduction of the experimental group was significantly higher than that of the control group (5.04±1.23 vs. 0.08±0.28, P < 0.05). Three days after surgery, PaO2 increase of the experimental group was significantly higher than that of the control group (7.42±3.59 mm Hg vs. 0.21±0.98 mmHg, P < 0.05). Conclusion It's reasonable and feasible to use pain scale greater than or equal to 6 and PaO2 less than 60 mm Hg as internal fixation indications for patients with multiple rib fractures.
