Effect of Methylene Blue on Perioperative Organ Function in Patients With Obstructive Jaundice

2019-10-04 08:31:36 | BioPortfolio


Increased production of vasodilating substances such as NO plays an important role in the development of vasoplegic syndrome caused by obstructive jaundice.Methylene blue plays a role in raising blood pressure by inhibiting the vasodilator Nitric Oxide (NO)


The level of circulating hydrogen sulfide (H2S) in patients with obstructive jaundice is significantly increased. As a direct opener of KATP channels in vivo, H2S also has diastolic peripheral vasculature . H2S participates in the occurrence of vasoplegic syndrome in patients with obstructive jaundice by interacting with NO. However, it is unclear whether methylene blue can relieve vasoplegic syndrome in patients with obstructive jaundice by inhibiting the vasodilating effect of substances such as H2S and NO.

Therefore, this clinical study intends to include patients with obstructive jaundice, using randomized, controlled, prospective study to explore the effect of methylene blue on the occurrence of vasoplegic syndrome, organ function and prognosis in patients with obstructive jaundice.

Medical and Biotech [MESH] Definitions

A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.

Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.

A genus of HALOBACTERIACEAE distinguished from other genera in the family by the presence of specific derivatives of TGD-2 polar lipids. Haloarcula are found in neutral saline environments such as salt lakes, marine salterns, and saline soils.

A clinical manifestation of HYPERBILIRUBINEMIA, characterized by the yellowish staining of the SKIN; MUCOUS MEMBRANE; and SCLERA. Clinical jaundice usually is a sign of LIVER dysfunction.

A family of gram-negative, moderately halophilic bacteria in the order Oceanospirillales. Members of the family have been isolated from temperate and Antarctic saline lakes, solar salt facilities, saline soils, and marine environments.
