??Abstract??The treatment of acute poisoning has always been a challenge in modern medicine??because there are so many types of poisonous materials and the poisoning individual varies??and the detoxification drugs with special effects are lacking.Extracorporal blood purification has an established role in the treatment of various intoxications.Hemoperfusion??hemodialysis??hemofiltration and plasmapheresis are effective methods for removal of toxin from the body and usually applied in selected cases of diagnosed severe forms as the options of fast elimination of the intoxicating agent.With the improvement of blood purification techniques and new life supporting systems??their clinical applications are rapidly increasing in number and scope.These methods have been applied whenever certain potentially lethal intoxications are diagnosed and/or suspected??even without evidence of life impediment at the time of institution of therapy.However??the large and high quality controlled trials are needed to prove the clear elimination of each type of intoxication by extracorporal blood purification techniques. 相似文献

百草枯(paraquat)为联吡啶类除草剂,化学名为1,1′-二甲基-4,4′联吡啶阳离子盐。随着百草枯在农业生产中的广泛应用,中毒事件日渐增多。虽然有关百草枯中毒的研究很多,但临床治疗效果仍然不能令人满意,病死率通常达50%~80%。结合笔者自身体会,现就百草枯中毒救治中的有关问题加以讨论。1百草枯中毒的诊断百草枯可以经消化道、皮肤和呼吸道吸收。一般情况下,完整的皮肤能够有效阻止百草枯的吸收,但长时间接触,如穿被百草枯溶液污染的衣服,阴囊或会阴部被污染,破损的皮肤大量接触,大面积皮肤被浓缩液污染,仍有可能造成全身毒性。百草枯不挥发… 相似文献

Valproic acid is increasingly used in the treatment of epilepsy, and also prescribed for bipolar affective disorders, schizoaffective disorders, schizophrenia and migraine prophylaxis. Valproic acid intoxication with suicide attempt is a relatively common clinical problem that can result in coma, respiratory depression, pancytopenia, hemodynamic instability and death. The drug's relatively low molecular weight, small volume of distribution and saturable protein-binding render it potentially amenable to exracorporeal removal (hemodialysis, hemoperfusion or hemofiltration ), but published experience is scarce. We describe a case report involving valproic acid intoxication with ingestion of ethanol, who was successfully treated with charcoal hemoperfusion. With this treatment the half-life of valproic acid was reduced with rapid lowering of valproic acid levels and clinical improvement. Based on our experience in this patient and a review of previously reported cases, charcoal hemoperfusion should be considered for serious valproic acid intoxication because free as well as bound drug fractions are eliminated via this technique. 相似文献

Aggressive removal of circulating free light chains (FLC) by blood purification accompanied by chemotherapy is a promising approach for the treatment of acute renal failure due to myeloma cast nephropathy. Plasma exchange has been performed to remove serum FLC; in order to examine an alternative strategy we performed hemodiafiltration using protein-leaking dialyzers for the treatment of dialysis-dependent acute renal failure due to myeloma cast nephropathy. In the first case with κ-light chain cast nephropathy, the pre-treatment serum creatinine was 9.65 mg/dL, and the serum κ-FLC was 27100 mg/L. Plasma exchange or hemodiafiltration was performed from Monday to Friday during the first several weeks. Chemotherapy was started with high-dose dexamethasone and then switched to bortezomib plus dexamethasone. The mean removal rates of κ-FLC were 45.8% (one plasma volume) and 66.9% (one-and-a-half plasma volumes) by plasma exchange. The removal rates of κ-FLC by hemodiafiltration (66.9%, FB210UHβ; 71.6%, PES210Dα; 75.2%, FXS220) were comparable to those by plasma exchange. In the second case with λ-light chain cast nephropathy, the pre-treatment serum creatinine was 4.14 mg/dL, and the serum λ-FLC was 4140 mg/L. The mean removal rates of λ-FLC were 60.2% (FXS140) and 64.2% (FB210UHβ) by hemodiafiltration. Both cases became dialysis-independent. The combination of an intense blood purification regimen and bortezomib plus dexamethasone therapy appears to be an efficient approach to renal recovery. Hemodiafiltration using protein-leaking dialyzers could become an alternative to plasma exchange as a method of removing FLC. 相似文献

AIM:To investigate an appropriate strategy for the treatment of patients with acute sigmoid volvulus in the emergency setting.METHODS:A retrospective review of 28 patients with acute sigmoid volvulus treated in the Department of Colorectal Surgery,Changhai Hospital,Shanghai from January 2001 to July 2012 was performed.Following the diagnosis of acute sigmoid volvulus,an initial colonoscopic approach was adopted if there was no evidence of diffuse peritonitis.RESULTS:Of the 28 patients with acute sigmoid volvulus,19(67.9%)were male and 9(32.1%)were female.Their mean age was 63.1 ± 22.9 years(range,21-93 years).Six(21.4%)patients had a history of abdominal surgery,and 17(60.7%)patients had a history of constipation.Abdominal radiography or computed tomography was performed in all patients.Colonoscopic detorsion was performed in all 28 patients with a success rate of 92.8%(26/28).Emergency surgery was required in the other two patients.Of the 26 successfully treated patients,seven(26.9%)had recurrent volvulus.CONCLUSION:Colonoscopy is the primary emergency treatment of choice in uncomplicated acute sigmoid volvulus.Emergency surgery is only for patients in whom nonoperative treatment is unsuccessful,or in those with peritonitis. 相似文献

Management with glucocorticoid, high iv fluid saline intake, furosemide and calcitonin may not result in a favorable reduction of hypercalcemia and may cause several side effects in infants with acute vitamin D intoxication. The bisphosphonate pamidronate, a specific inhibitor of bone resorption through osteoclast mediation was successfully used in a 6-month old infant with acute vitamin D intoxication managed in the Pediatric Emergency and Intensive Care Unit, after an ineffective trial of hydration, furosemide, calcitonin and prednisolone. After a double infusion of pamidronate on two consecutive days (1 mg/kg/day), an early and safe correction of hypercalcemia/hypercalciuria was supplied. Pamidronate therapy may be considered in patients with hypercalcemia secondary to acute vitamin D poisoning. 相似文献

Background/objectivesHypertriglyceridaemia increases risks from acute pancreatitis (HTG-AP) over other aetiologies, but optimal management for HTG-AP remains undefined. We performed a systematic review and meta-analysis of studies of insulin-based treatment (IT) versus blood purification treatment (BPT) for HTG-AP.MethodsSearches were conducted to identify randomised trials and observational studies published between 1946 and 2022 that compared IT and BPT for HTG-AP reporting baseline and post-treatment serum triglyceride (TG) levels with clinical outcomes. The primary outcome was serum TG reduction (Δ-TG) from baseline while secondary outcomes included complications, length of stay, adverse events, and cost.ResultsFifteen (1 randomised, 2 prospective case-controlled, and 12 retrospective cohort) studies were analysed comprising 909 cases with HTG-AP. Pooled results demonstrated IT was significantly less efficient than BPT in Δ-TG at 24 h (WMD -666.06, 95% CI -1130.18 to ?201.94, P = 0.005; 12 studies), at 48 h (WMD -672.60, 95% CI -1233.44 to ?111.77; 8 studies), and overall Δ-TG by day 7 (WMD -385.81, 95% CI -711.07 to ?60.54; 8 studies) (both P = 0.02). IT, however, was associated with significantly fewer adverse events (OR 0.09, 95% CI 0.03 to 0.27, P < 0.0001; 7 studies) and significantly reduced cost (WMD -2.50, 95% CI -3.61 to ?1.39, P < 0.00001; 3 studies). Other secondary outcomes were not significantly different between the two regimens (all P ≥ 0.11). In subgroup analysis Δ-TG at 24 h and overall Δ-TG became insignificant, while other results were unaffected.ConclusionOur findings support the general use of IT for inpatient management of HTG-AP, restricting BPT to those predicted or found to respond poorly to IT. 相似文献
