BACKGROUND Distal-to-proximal technique has been recommended for anticancer therapy administration. There is no evidence to suggest that a 24-hour delay of treatment is necessary for patients with a previous venous puncture proximal to the administration site. OBJECTIVES This study aims to identify if the practice of 24-hour delay between a venous puncture and subsequent cannulation for antic...

Specimens of skin-puncture serum and plasma and venous serum were simultaneously obtained from healthy adults and in each specimen the concentrations of 12 chemical constituents were measured. No clinically important difference was found in the concentrations of the constituents measured in skin-puncture serum and plasma with or without warming the skin before puncture. When the concentration o...

We compared the behaviours of rats, and measured various blood parameters, after three blood sampling techniques: orbital puncture while they were under diethyl-ether anaesthesia, blood collection by tail vein puncture under O2-N2O-halothane anaesthesia and puncture of the saphenous vein without anaesthesia. Twelve rats were subjected to the three treatments according to a Latin square design. ...

The spatial distribution and clinical correlation of cerebrospinal fluid leakage after lumbar puncture have not been determined. Adult in-patients receiving diagnostic lumbar punctures were recruited prospectively. Whole-spine heavily T2-weighted magnetic resonance myelography was carried out to characterize post-lumbar puncture spinal cerebrospinal fluid leakages. Maximum rostral migration was...

A simple and consistent puncture of the anterior stroma was created with the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser in a rabbit model. Varying energy levels were tested, and settings at 2.0 mJ produced well-formed anterior stromal breaks. The laser shock wave disrupted Descemet's membrane in only 1 of 50 animals. The wound healed normally in vivo over a 3-month period. Compared to nee...

When leaf epidermal cells are puncture wounded with a glass microcapillary tip, a small droplet of fluid is discharged and then evaporates, leaving a solid residue on the cell surface. For puncture wounds of about 3.5 micrometers in diameter, this process is complete within 2 to 3 seconds. A second puncture wound also exhibits a similar discharge, indicating the persistence of some turgor press...
