Tissue oxygen measurement and 31P magnetic resonance spectroscopy in patients with muscle tension and fibromyalgia.

Muscle tissue oxygen tension was measured by a polarographic oxygen fine-needle probe, and inorganic phosphate and creatine phosphate spectra were recorded using magnetic resonance spectroscopy in patients with chronic low back pain and in patients with fibromyalgia. Results were compared with healthy controls. The tissue oxygen tension was markedly higher in those with tense muscles than in normal subjects.

Monitoring cerebral oxygenation: experimental studies and preliminary clinical results of continuous monitoring of cerebrospinal fluid and brain tissue oxygen tension.

Cerebral ischaemia is considered to be the central mechanism leading to secondary brain damage in patients with severe head injury. It would therefore seem appropriate to monitor cerebral oxygenation in these patients. The possibilities of continuous monitoring of brain tissue and CSF oxygen tension as parameters for cerebral oxygenation were evaluated.

pO2-profiles in human muscle tissue as indicator of therapeutical effect in septic shock patients.

Automatically stepwise driven pO2 electrodes were transcutaneously inserted into muscle tissue of severely ill septic shock patients. The pO2 profile was plotted from 200 individual measurements registered during 5 minutes and a histogram plotted for documentation. Arterial and venous blood gases, cardiac output, systemic and pulmonary vascular resistance were measured continuously on-line.

[Tissue pO2 measurement in taut back musculature (m. erector spinae)].

Measurements with polarographic needle probes in fibromyalgic muscles (mm. erectores spinae) revealed an elevated mean tissue-pO2. The total mean tissue-pO2 in the patient group was significantly higher than that in the control group.
