Transcutaneous pO2 of volunteers during hyperbaric oxygenation.

Continuous transcutaneous pO2 measurements (tcPO2 measurements) were performed in healthy volunteers who were breathing air and oxygen under hyperbaric conditions (max. 4 ata). The results show a close correlation of PO2 values measured by the noninvasive method, in blood from discret arterial punctures, chamber PO2, respectively, the PO2 of the inspiratory gas mixture which was checked up to maximal values of 2,200 mm Hg. The PO2 in the arterial blood samples was measured immediately after the puncture insight the hyperbaric chamber using a specially designed through electrode.

[Placental transfer of carticaine (Ultracain) a new local anesthetic agent (author's transl)].

Serum levels of carticaine were measured in 9 parturient women after peridural anesthesia as well as in the newborns. The neonatal serum level of carticaine amounted to 32 +/- 7% of the maternal (ratio = 0,32). This proportion is compared to those given in the literature for the local anesthetics Lidocaine (0,52-0,58), Mepivacaine (0,64) and Bupivacaine (0,23-0,26).

[Transcutaneous PO2-measurement during heart catheterization in childhood (author's transl)].

Transcutaneous oxygen blood tension (tcpO2), heart rate, respiratory amplitude, respiratory rate, and relative local perfusion have been monitored continuously during heart catheterization in 37 children with congenital heart disease. The tcpO2 method allows an adequate measurement of the severity and duration of hypoxemia following arrhythmias or injection of contrast medium. The extent of hyperoxia following diagnostic procedures can also be controlled by this method.

Transcutaneous pO2 monitoring in anaesthesia.

In 23 patients 18 to 73 years old transcutaneous PO2, relative local perfusion and cardiorespirogram during induction and end stage of anaesthesia were monitored. This method allows continuous sufficiently exact estimation of PaO2. The comparison between tcPO2 and corresponding blood gas analysis from arterial samples showed a good correlation of r=0.94. Thus continuous tcPO2 registration enables quick diagnosis of hypoxia and its therapy.
