Peripartum anesthesia management and outcomes of patients with congenital heart disease: a single-center retrospective analysis (2009-2023).

Background: Advances in medicine have enabled more patients with congenital heart disease (CHD) to become pregnant. However, these patients face significant challenges during the peripartum period. Current peripartum anesthesia guidelines for CHD patients mainly rely on case reports and small series.

[BIOLOGICAL HERMETICITY, MECHANICAL STRENGTH AND MORPHOLOGICAL CHARACTERISTICS OF ONE-ROW AND TWO-ROW COLON ANASTOMOSES].

Aim - comparison of biological hermeticity, mechanical strength and differences in morphological characteristics of one-row and two-row colon anastomoses. 20 animals were used in the experiment. Rabbits of both sexes aged from 8 months to 1.

Oscillator strengths of UV absorption and luminescence for oxygen-deficient centers in germanosilicate fibers.

The time-resolved measurements of triplet and singlet luminescence from germanium oxygen-deficient centers (GODC's) in germanosilicate fibers excited by short UV laser pulses are used to determine the cross section of UV absorption of GODC's at lambda = 248 nm (sigma = 5 x 10(-18) cm(2)), the oscillator strength of UV absorption (f(abs) = 0.027), and UV luminescence (f(lum) = 0.031).

Correlation of defect centers with photoinduced second-harmonic generation in Er- and Sm-doped aluminosilicate fibers.

The spectral dependence of photoinduced optical losses after chi((2)) writing have been obtained in Sm- and Er-doped fibers. The results show that Sm(2+) and Er(2+) can be a source of photoelectrons during fiber preparation.

Photoinduced second-harmonic generation in fibers doped with rare-earth ions.

Photoinduced second-harmonic generation in silica fibers doped with Er(3+), Sm(3+), and Tb(3+) has been investigated. Er(3+)-doped fibers have been found to tune a chi((2)) grating easily to the mode structure of the laser radiation, whereas Sm(3+)-doped fibers have been found to possess the greatest resistance to chi((2)) grating erasure by radiation at 532 nm. From the beginning of the preparation processes, the third harmonic at 355 nm is registered in all the fibers.
