To retrospectively investigate the effects of indigo carmine intravenous injection on oxygen reserve index (ORi™) in 20 patients who underwent elective gynecologic surgery under general anesthesia. The study subjects were patients who underwent elective gynecologic surgery under general anesthesia between April 2016 and January 2017, and were administered a 5-ml intravenous injection of 0.4% indigo carmine for clinical purposes during surgery with ORi monitoring. Changes in ORi within 20 min after indigo carmine injection were observed. A relevant decrease in ORi was defined as ≥ 10% reduction in ORi from pre-injection level. ORi rapidly decreased after indigo carmine intravenous injection in all patients. In 10 of 19 patients, ORi decreased to 0 after indigo carmine injection. The median lowest value of ORi was 0 (range 0-0.16) and the median time to reach the lowest value of ORi was 2 min (range 1-4 min) after injection. ORi values returned to pre-injection levels within 20 min in 13 of 19 patients, and the median time to return to pre-injection levels was 10 min (range 6-16 min) after injection. During ORi monitoring it is necessary to consider the rapid reduction in ORi after intravenous injection of indigo carmine.

Background: Pit pattern diagnosis using crystal violet staining for colorectal tumors is useful for qualitative and depth diagnosis. However, due to its reported carcinogenic potential, the use of crystal violet has been restricted. This study was aimed at investigating the efficacy of texture and color enhancement imaging (TXI) magnification in pit pattern diagnosis.

The photocatalytic efficiency of TiO has been opposed by the fast recombination speed of photogenerated carriers. Here, g-CN -modified sulfate-built-in TiO quantum dots (ST-QDs) were successfully created using a simple ultrasonication-thermal procedure. g-CN-enrapped ST QDs with a 10 nm size were revealed by the characterization results.

Background: The detection of tumor localization is difficult in robotic surgery because surgeons have no sense of touch and rely on visual information. This study aimed to evaluate the efficacy of preoperative CT-guided dye marking of lung nodules prior to robotic surgery.
Methods: Patients undergoing CT-guided dye marking prior to robotic surgery at our hospital between September 2019 and April 2024 were retrospectively analyzed.

Purpose: During breast cancer surgery, the use of dyes such as indigo carmine, methylene blue, or indocyanine green (ICG) for targeting axillary lymph nodes (ALNs) under ultrasound guidance can result in rapid diffusion, complicated tissue differentiation, and disruption of staining. LuminoMark™, a novel ICG-hyaluronic acid mixture, can provide real-time visualization and minimize dye spread, thereby ensuring a clear surgical field. The aim of our study was to evaluate the efficacy of LuminoMark™ for targeting ALNs in patients with breast cancer.

At the scrub sink, we discussed the best ways to evaluate for ureteric patency during cystoscopy. For decades, surgeons have been using intravenous indigo carmine for evaluating ureteric patency. Ten years ago, a shortage of indigo carmine halted production.
