Laser-Doppler Flowmetry in Neurosurgery

Journal of Neurosurgical Anesthesiology, 1993
Laser-Doppler flowmetry (LDF) provides a reliable measurement of local cerebral blood flow (lCBF) as demonstrated by multiple validation studies. This article evaluates the clinical applications of LDF in neurosurgery. With the availability of modified probes, it is possible to carry out LDF monitoring of neurosurgical patients in the intensive care ...

Laser Doppler Flowmetry in Burn Wounds

Journal of Burn Care & Rehabilitation, 1995
Traditional methods for judgment of burn depth by clinical evaluation of the wound based on appearance and sensation remain in wide use but are subject to individual variation by examiner. In addition to the clinical difficulties with burn wound management, observer dependency of wound assessment complicates clinical trials of burn wound therapy.

Laser Doppler Flowmetry in Asymmetric Glaucoma

Current Eye Research, 2005
To evaluate the relationship between extent of glaucoma damage and optic nerve blood flow, we investigated optic nerve head bloodflow in patients with asymmetric glaucoma damage between their two eyes and also in glaucomatous eyes with asymmetric damage inferiorly versus superiorly.From our institutional practice, 16 subjects with asymmetric glaucoma ...

[Laser-Doppler flowmetry].

Nihon rinsho. Japanese journal of clinical medicine, 1992
Laser-Doppler flowmetry (LDF) is a non-invasive technique for measuring the tissue blood flow. It has been shown in the skin that LDF discloses blood flow fluctuations due to vasomotor nerve activity. LDF can give measurements of blood flow at various sites of different tissue.

Laser doppler flowmetry in the hyperbaric environment

Lasers in Medical Science, 1997
Continuous monitoring of laser Doppler (LD) flowmetry was performed in eight healthy volunteers (mean age 42.0 + 12.1 yr; range 25-62 yr) before, during and after hyperbaric oxygenation ([HBO at 2.5 and 1.95 ATA (atmosphere absolute)]).Two models of the discrimination analysis are presented which allow classification, resulting from the parameter ...

Waveform analysis applied to laser doppler flowmetry

Microsurgery, 1986
AbstractLaser Doppler flowmetry (LDF) has been found useful in monitoring free flaps. In the present study, waveform analysis has been applied to the LDF waveform. Waveform changes were investigated in the microcirculation during varying degrees of arterial or venous occlusion in the saphenous island and flap of the dog and the human digit.

Vaginal Laser Doppler Flowmetry Pre- and Posthysterectomy

Journal of Sex & Marital Therapy, 2004
The objective of this study was to demonstrate the applicability of laser doppler flowmetry to pre- and posthysterectomy vaginal blood flow assessment. We used laser Doppler flowmetry to measure pre-and postoperational vaginal blood flow in 8 premenopausal women undergoing benign hysterectomies; we also measured serum E2, FSH, FT and administered a ...

Laser Doppler Flowmetry for monitoring traumatized teeth

Dental Traumatology, 2001
Abstract – Laser Doppler Flowmetry (LDF) has been shown to be valuable in monitoring revascularization of immature incisors following severe dental trauma. Several investigators have demonstrated the ability of LDF to record blood flow signals from vital tooth pulps.

Application of Laser Doppler Flowmetry in Neurosurgery

Neurosurgery Clinics of North America, 1996
Experience with LDF has indicated that intraoperative estimation of cerebral blood flow can be very useful and that long-term recordings of cortical perfusion pressure are possible. The disadvantage of LDF is that measurements are extremely local and that the units of measurements are arbitrary.

Principles of Laser-Doppler Flowmetry

1990
Light scattering has long been used to probe properties of bulk matter. In transparent media such as air or clear water, measurements can be analyzed easily and remote sensing can be done over great distances. The basic principles relating the intensity of scattered light to underlying molecular structure were established by Lord Rayleigh in his ...
