Acute lung injury is a kind of common complication after cardiopulmonary bypass. Acute lung injury is attributed to the ischemia-reperfusion injury and systemic inflammatory response syndrome. Several factors common in cardiac surgery with cardiopulmonary bypass may worsen the risk for acute lung injury including atelectasis, transfusion requirement, older age, heart failure, emergency surgery and prolonged duration of bypass. Targets for prevention of acute lung injury include mechanical, surgical and anesthetic interventions that aim to reduce the contact activation, systemic inflammatory response, leukocyte sequestration and hemodilution associated with cardiopulmonary bypass. We aim to review the etiology, risk factors and lung protective strategies for acute lung injury after cardiopulmonary bypass.
ObjectiveTo evaluate the effectiveness of Ilizarov technique-based transverse tibial bone transport on the treatment of severe diabetic foot ulcer (Wagner grades 3 to 5) complicated with systemic inflammatory response syndrome (SIRS).MethodsBetween August 2014 and December 2017, 33 patients with severe diabetic foot and SIRS were treated with Ilizarov technique-based transverse tibial bone transport. There were 27 males and 6 females, with a mean age of 60.6 years (range, 34-79 years). All of them suffered from type 2 diabetes mellitus. The duration of diabetes was 1-28 years (mean, 10 years) and the duration of diabetic foot was 1-12 months (mean, 2.7 months). According to Wagner classification, there were 8 cases in grade 3, 23 cases in grade 4, and 2 cases in grade 5. The wound healing condition was observed after operation, and the limb salvage rate was calculated. The changes in body temperature, heart rate, respiratory rate, white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were assessed. The skin temperature of the dorsum of the foot was measured, and the visual analogue scale (VAS) score was used to evaluate the improvement of foot pain.ResultsAll 33 patients were followed up 3-30 months (mean, 14.1 months). All ulcers healed and the healing time was 3-12 months (mean, 5.3 months); the limb salvage rate was 100%. Postoperative body temperature, heart rate, respiratory rate, white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were significantly lower than those before operation (P<0.05). The skin temperature of the dorsum of the foot was (32.64±2.17)℃ at 1 month after operation, which was significantly improved when compared with preoperative value [(31.28±1.99)℃] (t=0.05, P=0.00); but there was no significant difference in skin temperature compared with healthy side [(32.46±2.10)℃] (t=2.04, P=0.41). The VAS score was 2.4±0.7 at 1 month after operation, which was significantly improved when compared with preoperative score (4.3±0.8) (t=3.10, P=0.00).ConclusionIlizarov technique-based transverse tibial bone transport is an effective way to treat severe diabetic foot complicated with SIRS. It can promote foot ulcer healing and avoid amputations.
ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.
Radiofrequency ablation for hepatic hemangioma is safe and effective, and can obtain the same curative effect as traditional surgical resection. For hepatic hemangiomas with large volume, abundant arterial blood supply and long ablation time, systemic inflammatory response syndrome (SIRS) often occurs after radiofrequency ablation, which can lead to injury or dysfunction of important organs. This paper systematically summarizes the mechanism, prevention and treatment of SIRS after radiofrequency ablation of hepatic hemangioma, so as to provide reference for improving the safety of radiofrequency ablation of hepatic hemangioma.
