Introduction
The high cost of critical care resources has resulted in strategies to reduce the costs of ruling out low-risk patients by developing intermediate care units (IMCs). The aim of this study was to compare changes in total hospital costs for intensive care patients before and after the introduction of an IMC at the University Hospital Maastricht. 相似文献722.
Background
The life-time incidence of low back pain is high and diagnoses of spinal stenosis and disc prolapse are increasing. Consequently, there is a steady rise in surgical interventions for these conditions. Current evidence suggests that while the success of surgery is incomplete, it is superior to conservative interventions. A recent survey indicates that there are large differences in the type and intensity of rehabilitation, if any, provided after spinal surgery as well as in the restrictions and advice given to patients in the post-operative period. 相似文献723.
Endometrial perfusion across the normal human menstrual cycle assessed by laser Doppler fluxmetry 总被引:1,自引:5,他引:1
This study investigated variations in microvascular perfusion of human
endometrium across the menstrual cycle, using a laser Doppler technique to
assess red blood cell (RBC) flux. Endometrial RBC flux was monitored by
laser Doppler fluxmetry via a fibre optic probe inserted transvaginally
into the uteri of 19 conscious normal volunteer women, on four occasions at
weekly intervals over one menstrual cycle. Regional variation in RBC flux
was investigated in 16 surgical patients under general anaesthesia and in
five excised uteri. Endometrial perfusion exhibited short-term temporal
variations consistent with the cardiac cycle and often also showed
vasomotion (5-12 cycles/min). Mean endometrial perfusion differed between
phases of the menstrual cycle in conscious women, being highest during
early proliferative and early follicular phases. There were no significant
regional differences in local mean endometrial perfusion in anaesthetized
patients. No evidence of endometrial ischaemia/reperfusion episodes was
found in any subject using this technique. This study provides benchmark
data of variations in RBC flux per unit volume of tissue in the luminal
approximately 1 mm of endometrium, across the normal human menstrual cycle.
Flux values were highest at times associated with endometrial growth and
preparation for implantation, indicating that RBC flux may be a useful
parameter for assessment of endometrial physiology.
