We report a case of first-degree atrioventricular (A-V) block progressing to second-degree (Wenckebach-type) A-V block after administration of indigo carmine in a patient undergoing hysterectomy under general anesthesia. We believe that the onset of Wenckebach-type A-V block may have been induced by one or more of three factors: 1) preoperative first-degree A-V block, 2) the anesthetics used (p...

Indigo carmine forms a stable complex with different ions, and the stability constant of the complexes were evaluated as log K equal to 5.75; 5.00; 4.89 and 3.89 for complexes with Cu(II), Ni(II), Co(II) and Zn(II) ions, respectively, in 0.1 mol L-1 carbonate buffer solution at pH 10. The interaction between Cu(II) ions and indigo carmine (IC) in alkaline medium resulted in the formation of the...

OBJECTIVES To determine the incidence of and risk factors for injury to the lower urinary tract during total laparoscopic hysterectomy. METHODS All patients who underwent total laparoscopic hysterectomy for benign disease from January 1, 2002 to December 31, 2005, at an academic medical center are included. Subjects undergoing laparoscopic-assisted vaginal hysterectomy, supracervical hysterec...

  Abstract: Spectrophotometric studies were successfully used in quantitative analysis of Amitriptyline Hydrochloride (ATH) Two new methods using spectrophotometry are described for the determination of (ATH) with potassium bromate as the oxidizing agent and acid dyes, Methyl orange and Indigo carmine. Both spectrophotometric methods are based o...

a simple, economical, precise and fast visible spectrophotometric method has been developed for the determination of azathioprine in tablet dosage form. developed method is based on the formation of extractable colored complex of drug with colouring agent indigo carmine and methyl orange. a wavelength maximum was found to be 683.7 nm and 566 nm. the concentration range of 15-50 μg ml-1 with of ...

The degradation of the dye indigo carmine in aqueous solution induced by two oxidative processes (H(2)O(2)/iodide and O(3)) was investigated. The reactions were monitored by electrospray ionization mass spectrometry in the negative ion mode, ESI(-)-MS, and the intermediates and oxidation products characterized by ESI(-)-MS/MS. Both oxidative systems showed to be highly efficient in removing the...

Introduction. To compare the accuracy of digital and real-time chromoendoscopy for the differential diagnosis of diminutive (<5 mm) neoplastic and nonneoplastic colorectal lesions. Materials and Methods. This is a prospective randomized study comparing the Fujinon intelligent color enhancement (FICE) system (65 patients/95 lesions) and indigo carmine (69 patients/120 lesions) in the analysis of...
