Objective To testify the efficacy of revised trauma score （RTS） in evaluating the severity of trunk injury，analyze its inadequacy and make modifications to improve its specificity and accuracy in evaluating trunk injury. Methods Medical records of 278 patients undergoing emergency surgery for the treatment of trunk injury in West China Hospital of Sichuan University between January 2006 and June 2012 were retrospectively analyzed. There were 231 males and 47 females in the age of 1-75 （33.7±14.1） years. RTS was calculated for each patient. Hemoglobin （Hb） concentrations in these patients acquired at the emergency room were included to reflect the severity of blood loss. The correlations between RTS and patient response to treatment as well as RTS and prognosis were analyzed. Patient response to treatment and prognosis were compared between the normal RTS group and the abnormal RTS group. Univariate analysis was performed followed by multivariate analysis for the variables which may impact prognosis. Modified RTS was established by regression analysis. Results RTS was significantly correlated with patient response to treatment as well as prognosis. RTS was significantly correlated with the time duration between the onset of injury and the beginning of operation （r =0.249，P＜0.001）， thoracic and abdominal blood loss volume （r = -0.255，P＜0.001），fluid resuscitation volume （r = -0.244，P＜0.001） as well as length of ICU stay （r = -0.202，P=0.001）. Mortalities in patients with different RTS were statistically different （P=0.004）. In the patient group with normal RTS the mortality was 5.1%，which indicates the inadequacy of RTS in evaluating trunk injury. Univariate analysis revealed that both emergency room Hb and RTS were correlated with patients’ prognosis. After putting these two factors into the regression analysis，a new formula to calculate modified RTS is established：Logit （P death）=6.450-0.769×RTS-0.029×Emergency room Hb. Conclusion Modified RTS is more specific in evaluating trunk injury and maintains the advantages of simplicity and rapidness.
Objective To summarize the experience of emergency coronary artery bypass grafting （CABG） after failed percutaneous coronary intervention. Methods From January 1998 to December 2002, 9 patients underwent emergency CABG after failed percutaneous coronary intervention. The indications of emergency CABG were coronary artery dissection （5 cases）or perforation （2 cases） and acute arterial occlusion （2 cases）. The time averaged 2 hours from onset of ischernia to revascularization. The CABG was performed under off-pump bypass in 3 cases and under CPB in 6 cases. The mean graft number was 3. Results There were no hospital death. The mean follow-up was 17 months. No death and angina occurred. The function of New York Heart Association class Ⅰ-Ⅱ were in 8 patients, class Ⅲ in 1 patient. Conclusion Emergency CABG is an effective management for failed percutaneous coronary intervention if the indication is right.
Objective To summarize the experience of emergency coronary artery bypass grafting(CABG) on serious myocardium ischemia in early post CABG. Methods Between 1998 and 2002, emergency redo CABG was performed in 13 patients with serious early post operative myocardium ischemia. The causes included vein graft embolize(4 cases),uncompleted revascularize(3 cases), graft spasm(1 case) and anastomose stenosis or occlusion (5 cases). The grafts was 1 3(1.8±0.9) during redo CABG. Results There were 6 deaths, the mortality was 46%. The mean follow up was 31 months. There was no recurrence of angina. NYHA function was Ⅰ Ⅱ. Conclusion Emergency CABG is an important method in saving the patients with severe myocardium ischemia in early post CABG. The perioperative prevention and early treatment should be emphasized.
