    Description / Table of Contents: Abstract A 3.5-year-old girl suffered from a thermal injury affecting 37% of the body surface area. The parents, being Jehovah's witnesses, refused permission for their child to receive blood transfusions. As the haemoglobin level was only 7.5% and a necrectomy was planned, the patient was likely to need blood transfusions. Indications for transfusion were defined as clinical signs of hypoxia and/or cardiovascular instability. A judicial declaration was proposed. Hb decreased during the therapy. To stimulate the erythropoiesis erythropoietin and iron were administered. During the clinical course the anaemia worsened. First, a conservative treatment with polyvidoniodine ointment for tanning was started, to avoid an operation during the acute phase after the injury, as in this case it was thought a blood transfusion would definitely be necessary. On the 19th day after the injury a necrectomy of 10% of the body surface was necessary because of fever and leucocytosis not responding to antibiotics. The most likely cause of the symptoms was an infection of the burned area. Hb was 4.6 g/dl%. General anaesthesia was performed with midazolam, ketamine and vecuronium and mechanical ventilation. No blood transfusion was required during the operation.Vital signs were stable during the preoperative period, during anaesthesia and following the operation. There were no signs of tissue hypoxia. Peripheral oxygen saturation ranged between 98% and 100%, lactate and arterial blood gas samples were normal, and the child was awake and cooperative before and after anaesthesia. The lowest Hb was 3.3 g/dl on the 22th day after injury (3rd postoperative day). In this phase the patient was still playing and riding a tricycle. On the 45th day after injury the child was discharged home with Hb of 10.9 g/dl and reticulocytosis of 33%.
    Notes: Zusammenfassung Ein 3,5jähriges Mädchen, dessen Eltern als Zeugen Jehovas eine Bluttransfusion bei ihrem Kind kategorisch ablehnten, wurde mit einer Verbrennung von 37% der Körperoberfläche und einem Hb von 7,5 g/dl zur Operation verlegt. Als Transfusionsindikationen wurden für den stationären Aufenthalt klinische Zeichen einer Hypoxie und/oder Kreislaufinstabilität festgelegt. Es wurde eine richterliche Verfügung erwirkt, die den Eltern das Sorgerecht für die medizinischen Maßnahmen entzog, um ggf. bei oben beschriebener Indikation eine Transfusion durchführen zu können. Im Verlauf der Behandlung nahmen Hb und Hk weiter ab. Trotz Gabe von Erythropoetin und Eisen konnte die Erythropoese nicht stimuliert werden. Um eine Operation im Akutstadium zu vermeiden, die mit einer hohen Wahrscheinlichkeit eine Bluttransfusion erforderlich gemacht hätte, wurde primär eine konservative Therapie mit einer Gerbung durch Polyvidon-Jodsalbe durchgeführt. Aufgrund einer nekrosebedingten systemischen Infektion erfolgte am 19. Tag eine Nekrosektomie von ca. 10% der Körperoberfläche mit Deckung durch Eigenhaut vom Unterschenkel in intravenöser Anästhesie und kontrollierter Beatmung (Ketamin/Midazolam/Vecuronium). Der Hb betrug präoperativ 4,6 g/dl, der Hk 14%. Da das Kind während des gesamten stationären Aufenthalts kreislaufstabil war und keine Zeichen einer Hypoxie auftraten, wurde keine Transfusion durchgeführt. Der niedrigste Hb betrug am 22. Tag nach Unfall (=3. postoperativer Tag) 3,3 g/dl. Am 45. Tag nach Unfall wurde das Kind mit einem Hb von 10,9 g/dl und 33% Retikulozyten im Differentialblutbild nach Hause entlassen.

    Notes: High-resolution Stokes and anti-Stokes Raman spectra of isotopically pure 127I79Br were recorded with excitation by argon ion laser radiation using CCD camera detection and a scanning multi-channel technique. The observed spectra show a complex rotational-vibrational structure, which can be explained in terms of Q branches, S band heads, unresolved O branches and corresponding hot band transitions. The spectral band shapes of the fundamental vibrational transitions and of several overtones were studied as a function of laser power and excitation wavelength. A symmetry principle between Stokes and anti-Stokes spectra is also demonstrated. In addition, hyperfine structure in the electronic Raman spectra of atomic 127I and 79Br was observed under high resolution.

    Notes: High-resolution Raman spectra of isotopically pure 35Cl2 were recorded using UV argon ion laser radiation of 275.4, 300.3, 302.4 and 305.5 nm. Overtone progressions could be observed for excitation with 300.3, 302.4 and 305.5 nm radiation. All overtone transitions could be simulated satisfactorily using both the traditional Kramers-Heisenberg-Dirac equation and time-dependent quantum theory. The results obtained for 35Cl2 are compared to those derived earlier for I2 and Br2. The spectral features of the fundamental band for excitation in the UV region can be explained by assuming a destructive interference effect between resonant and non-resonant Raman scattering resulting from adjacent high-energy electronic states.
