Increased microvascular water permeability in patients with septic shock, assessed with venous congestion plethysmography (VCP)

Intensive Care Medicine, 1998
To investigate microvascular water permeability (filtration capacity, Kf) in patients with septic and non-septic shock using a new non-invasive method for studying microvascular parameters in man.Intensive Care Unit of a university hospital.We investigated 28 patients, presenting with cardio-vascular instability due to either septic shock, or non ...

Do dressings with increased permeability reduce the incidence of central venous catheter related sepsis?

Intensive and Critical Care Nursing, 1997
The incidence of catheter-related sepsis associated-with the use of Tegaderm or Opsite IV3000 dressings on 100 critically ill patients with liver disease was studied. All the patients had central venous catheters in situ and they were randomly assigned to one of the two dressings.

Permeability pulmonary edema caused by venous air embolism.

The American review of respiratory disease, 1984
A 22-yr-old man developed severe pulmonary edema after blowing air into tubing connected to a catheter inserted in a vein in his forearm. Pulmonary edema was rapid in onset, peaking in intensity about 12 h after the air had been insufflated. The patient's edema fluid to plasma protein concentration ratio of 0.79 showed that the edema fluid was rich in ...

[Permeability of venous aortocoronary bypass 5 years later].

Archives des maladies du coeur et des vaisseaux, 1979
47 consecutive patients who had undergone aorto-coronary venous bypass surgery (mean: 1.6 graft per patient) have been investigated after a mean follow-up period of 5 years and 9 months (range: 44-108 months). 52 grafts out of 73 were found to be patent (71 p. 100), the best patency rate being shown by grafts on the LAD artery (27/32 = 85 p. 100).

Diapedesis and the permeability of venous microvessels to protein macromolecules: The impact of leukotriene B4 (LTB4)

Microvascular Research, 1988
The cellular basis of the reported neutrophil-dependent increase in microvascular permeability evoked by leukotriene B4 (LTB4) was probed using protein intravascular fluorescent and electron dense tracers in conjunction with intravital, light and electron microscopy. LTB4 (1 microM) applied topically to the hamster cheek pouch promoted neutrophil (PMN)

A note on the errors of using venous congestion in intact rats for determinations of microvascular permeability

Acta Physiologica Scandinavica, 1991
The established ideas of transcapillary exchange have recently been challenged based on studies in intact rats. In vivo measurements of net fluid flux and albumin clearance in muscle (and skin) have given estimates of the reflection coefficient (s̀) for albumin of 0.98–0.99 compared to the s̀ value of 0.90 obtained by most other techniques.

Extensive Brain Swelling with Neurological Deterioration after Intracranial Meningioma Surgery - Venous Complication or ‘Unspecific’ Increase in Tissue Permeability

Zentralblatt für Neurochirurgie - Central European Neurosurgery, 2008
We retrospectively analyzed a series of patients who deteriorated after resection of an intracranial meningioma due to extensive brain edema (EBE) with regard to etiology of the neurological worsening and outcome.Out of a series of 376 consecutive patients who underwent resection of an intracranial meningioma, 13 (3.5%) experienced postoperative ...

[Permeability of venous aortocoronary bypasses one year after their implantation].

Archives des maladies du coeur et des vaisseaux, 1987
For a short-term evaluation of the patency of aortocoronary bypass vein grafts, 54 consecutive patients who underwent this operation alone were examined, irrespective of their functional state, 12.4 +/- 2.1 months after surgery. Examinations included coronary arteriography, selective opacification of the graft and ventriculography. The patients were 47

Microvascular permeability, venous stasis and oedema.

International angiology : a journal of the International Union of Angiology, 1990
Microvascular permeability to fluid and hydrophilic solutes is restricted to channels between the endothelial cells and through the fenestrations when these are present. The channels have a molecular filter which appears to be a lattice of fibrous molecules reinforced by plasma proteins.

Permeability of human venous endothelial cell monolayers perfused in microcarrier cultures: Effects of flow rate, thrombin, and cytochalasin D

Journal of Cellular Physiology, 1991
AbstractWe have applied a multiple isotope dilution technique to examine junctional permeability of human umbilical vein endothelial cells (HUVEC) in vitro. Primary cultures were grown to confluence on porous Cytodex‐3 microcarrier beads, packed into 0.3 ml columns (3 × 106 cells) and perfused at varying flow rates (0.3–1.2 ml/min) with HEPES‐buffered ...
