Background
The placement of a central venous catheter for the administration of vasopressors is still recommended and required by many institutions because of concern about complications associated with peripheral administration of vasopressors.Objective
Our aim was to determine the incidence of complications from the administration of vasopressors through peripheral venous catheters (PVC) in patients with circulatory shock, and to identify the factors associated with these complications.Methods
This was a prospective, observational study conducted in the emergency department (ED) of a tertiary care medical center. Patients presenting to the ED with circulatory shock and in whom a vasopressor was started through a PVC were included. Research fellows examined the i.v. access site for complications twice daily during the period of peripheral vasopressor administration, then daily up to 48 h after treatment discontinuation or until the patient expired.Results
Of the 55 patients that were recruited, 3 (5.45% overall, 6% of patients receiving norepinephrine) developed complications; none were major. Two developed local extravasation and one developed local thrombophlebitis. All three complications occurred during the vasopressor infusion, none in the 48 h after discontinuation, and none required any medical or surgical intervention. Two of the three complications occurred in the hand, and all occurred in patients receiving norepinephrine and with 20-gauge catheters.Conclusions
The incidence of complications from the administration of vasopressors through a PVC is small and did not result in significant morbidity in this study. Larger prospective studies are needed to better determine the factors that are associated with these complications, and identify patients in whom this practice is safe. 相似文献6.

Dynamic contrast-enhanced ultrasonography (DCE-US) using a second-generation contrast agent and perfusion software is a new
technique enabling a quantitative assessment of solid tumor perfusion using raw linear data. Clinical trials have shown that
it can be used to assess the anticancer efficacy of antiangiogenesis treatment, for which conventional, size-based efficacy
criteria are unsuitable. Reduction in tumor vascularization can easily be detected in responders after 1 or 2 weeks and is
correlated with progression-free survival and overall survival. DCE-US is supported by the French National Cancer Institute
(INCa), which is currently studying the technique in metastatic breast cancer, melanoma, colon cancer, gastrointestinal stromal
tumors and renal cell carcinoma, as well as in primary hepatocellular carcinoma, to establish the optimal perfusion parameters
and timing for quantitative anticancer efficacy assessments. 相似文献

The usefulness and safety of transesophageal echocardiography during cardiac surgery have been well described in the literature. However, rare complications of this procedure can occur and should be familiar to surgeons and anesthesiologists. A case of esophageal perforation by echoprobe during coronary artery bypass grafting treated successfully by endoscopic stenting is reported. 相似文献
