Povidone-iodine in umbilical cord care interferes with neonatal screening for hypothyroidism 总被引:2,自引:0,他引:2
Out of 1346 newborns screened for congenital hypothyroidism, 31 non-hypothyroid infants were summoned because of a thyroid stimulating hormone (TSH) level above 10 U/ml. False-positive TSH levels were significantly more frequent in the babies treated with povidone-iodine (4.6%) than in those treated with either alcohol or triple dye (0.7%).Conclusion Iodine containing solutions should be avoided in umbilical cord care of the newborn 相似文献

PURPOSE: Exfoliated or soiled free malignant cells have serious consequences in patients undergoing gastrointestinal cancer surgery. The present study evaluates the toxicity and efficacy of cytotoxic agents in the prevention of cell seeding and tumor growth in the peritoneal cavity in an experimental model. METHODS: Mtln3 adenocarcinoma cell viability was testedin vitro using the trypan blue exclusion test after incubation with povidone-iodine or chlorhexidine.In vivo, Fischer rats were inoculated with 105 or 106 cells followed by peritoneal lavage with physiological saline, chlorhexidine 0.02 percent, providone-iodine low molecular weight 1 percent or povidone-iodine high molecular weight 1 and 2 percent in different quantities and incubation times. RESULTS: Chlorhexidine 0.02 percent and povidone-iodine low molecular weight 1 percent or high molecular weight 2 percent, killed over 98 percent of 105 or 106 tumor cellsin vitro. Povidone-iodine low molecular weight 1 percent and high molecular weight 2 percent were toxic and lethal when 5 ml were applied in the peritoneal cavity three times for five minutes. Chlorhexidine 0.02 percent applied after inoculation of 105 or 106 cells, reduced the tumor development only to 70 and 80 percent. Application of 5 ml povidone-iodine 1 percent low molecular weightor high molecular weight, three times for one and five minutes, after inoculation of 106 cells did not change the tumor take. However, inhibition of Mtln3 cells to form metastases was observed. When povidone-iodine low molecular weight 1 percent was used three times for one minute after 105 tumor cells were soiled, no toxicity was observed and the tumor take was reduced to 30 percent (P<0.05). CONCLUSIONS: Povidone-iodine toxicity proved to be a major issuein vivo. However, povidone-iodine low molecular weight 1 percent was safe when used for short periods and very effective when a limited number of tumor cells was inoculated. The use of cytotoxic agents to prevent recurrent disease caused by tumor cell seeding in patients seems to make sense only when the inoculum size of exfoliated or soiled cancer cells is limited. 相似文献

Purpose: To evaluate the effect of PVP-I liposome hydrogel on intraperitoneal postoperative adhesions. Material and Methods: Thirty Wistar-Albino male rats were randomly divided into three groups. After midline laparotomy, a 1 cm2 area of the caecum was abraded with a sterile gauze until subserosal haemorrhage had developed. A 1 χ 1 cm patch of peritoneum located opposite of caecal abrasion was completely dissected. In group 1 (control group, C) adhesion induction was performed and nothing was applied to the wounds. In group 2 and 3, PVP-I solution (3%) (group 2, PI) and PVP-I liposome hydrogel (group 3, PIL) were applied to the caecal abrasion areas and peritoneal defects. Adhesions were classified according to a classification system based on the evaluation of the appearance, extent and strength of the adhesions on postoperative 21st day.Results: There was no significant difference of the adhesion scores between the groups (U1 = 45, p > 0.05; U2 = 48, p > 0.05; U3 = 47.5, p > 0.05).Conclusions: We found that PVP liposome hydrogel did not influence postoperative intraabdominal adhesions and should be further explored for its potential use in various intraabdominal procedures. 相似文献

Objective Central venous catheter (CVC)-related infections may be caused by micro-organisms introduced from the skin surface into deeper tissue at the time of CVC insertion. The optimal disinfection regimen to avoid catheter-related infections has not yet been defined. This study compares three different approaches.Design Prospective randomised trial.Setting A tertiary care hospital.Patients and participants One hundred nineteen patients scheduled electively to receive 140 CVCs.Interventions Skin disinfection was performed with either povidone-iodine 10% (PVP-iodine), chlorhexidine 0.5%/propanol 70%, or chlorhexidine 0.5%/propanol 70% followed by PVP-iodine 10%. Prior to disinfection, a swab from the site of insertion was taken for culture. CVCs were removed if no longer needed or infection was suspected. All catheters were cultured quantitatively after removal.Measurement and results Bacteria could be isolated from 20.7% of the catheter tips. Bacterial growth was found in 30.8% of the catheters placed after skin disinfection with povidone-iodine, in 24.4% after disinfection with propanol/chlorhexidine and in 4.7% after disinfection with propanol/chlorhexidine followed by povidone-iodine (p=0.006). In 15 cases, the same organism was isolated from the skin swab and the catheter tip. Ten of these paired isolates showed the same pattern in a pulsed-field gel electrophoresis analysis.Conclusions Skin disinfection with propanol/chlorhexidine followed by PVP-iodine was superior in the prevention of microbial CVC colonisation compared to either of the regimens alone. These results support the concept that catheter infections can originate from bacterial translocation at the time of catheter insertion. 相似文献

目的比较两种不同浓度(0.05%与0.025%)碘伏液(聚维酮碘)在白内障术前冲洗结膜囊后,患者角膜荧光染色、主觉症状、结膜囊细菌培养等方面的差异,以期找到更安全、有效的白内障术前冲洗结膜囊的碘伏液浓度。方法选择住院行白内障超声乳化术的患者83例(83只眼),随机分为A、B两组,术前分别采用0.05%碘伏液(A组)、0.025%碘伏液(B组)冲洗结膜囊,比较两组术后患者主观症状、术眼眼表荧光素钠染色评分的差异,以及术前、术后结膜囊采样细菌学培养情况。结果A、B两组浓度的聚维酮碘稀释液均能达到相同的结膜囊细菌消毒效果,但B组较之A组术后患者眼部感觉更舒适,同时客观的眼表损伤更轻微。结论较低浓度(0.025%)的聚维酮碘液在保证有效清除结膜囊细菌的同时,还能明显地降低术后患者的主观不适症状和客观的眼表损伤体征,有利于视功能的更快恢复,可作为临床推广应用。 相似文献
