Abstract Background: The determination of reference intervals for the concentration of total S-nitrosothiols (RSNOs) in blood is a highly controversial topic, likely because of the inherent instability of these species. Most currently available techniques to quantify RSNOs in blood require considerable sample handling and multiple pretreatment steps during which light exposure is difficult to completely eliminate. We investigated the effect of brief light exposure on the stability of RSNO species in blood during the initial sampling process. Methods: A novel amperometric RSNO sensor, based on an immobilized organoselenium catalyst at the distal tip of an electrochemical nitric oxide detector, was used to determine RSNO species in diluted whole blood without centrifugation or pretreatment. Porcine blood was collected into aluminum foil–wrapped syringes via a 12-inch butterfly needle tube assembly. Two blood samples were collected from the same animal—one with the butterfly needle tubing wrapped in aluminum foil and one with the tubing exposed to ambient room light. The RSNO concentrations in these sequential blood samples were determined by a standard addition procedure. Results: Eight sets of measurements were made in 6 animals. Samples exposed to light yielded RSNO concentrations only 23.6% (7.2%) [mean (SD)] of the RSNO concentrations determined in samples that were shielded from light and obtained from the same animals. Conclusions: These results suggest significant photoinstablity of RSNOs in whole blood and indicate the critical importance of proper light protection during sampling and processing of blood samples for the accurate determinations of endogenous RSNO concentrations.

AbstractObjective:To compare the percutaneous injury rate associated with a standard versus a safety resheathable winged steel (butterfly) needle.Design:Before-after trial of winged steel needle injuries during a 33-month period (19-month baseline, 3-month training, and 11-month study intervention), followed by a 31-month poststudy period.Setting:A 1,190-bed acute care referral hospital with inpatient and outpatient services in New York City.Participants:All healthcare workers performing intravascular-access procedures with winged steel needles.Intervention:Safety resheathable winged steel needle.Results:The injury rate associated with winged steel needles declined from 13.41 to 6.41 per 100,000 (relative risk [RR], 0.48; 95% confidence interval [CI95], 0.31 to 0.73) following implementation of the safety device. Injuries occurring during or after disposal were reduced most substantially (RR 0.15; CI95, 0.06 to 0.43 Safety winged steel needle injuries occurred most often before activation of the safety mechanism was appropriate (39%); 32% were due to the user choosing not to activate the device, 21% occurred during activation, and 4% were due to improper activation. Preference for the safety winged steel needle over the standard device was 63%. The safety feature was activated in 83% of the samples examined during audits of disposal containers. Following completion of the study, the safety winged steel needle injury rate (7.29 per 100,000) did not differ significantly from the winged steel needle injury rate during the study period.Conclusion:Implementation of a safety resheathable winged steel needle substantially reduced injuries among healthcare workers performing vascular-access procedures. The residual risk of injury associated with this device can be reduced further with increased compliance with proper activation procedures.

The Central Nervous System

The drug discovery and pharmacokinetic studies of drugs of the central nervous system depend on the successful collection of cerebrospinal fluid from lab animal models. Many a time, the treatment regime and management of diseases depends on the penetration and distribution of medicaments across the blood-brain barrier and for which a non-contaminated cerebrospinal fluid sample is essential. The present study was to simplify the cerebrospinal fluid collection from cisterna magna of rat, maximizing the quantity and minimizing the contamination. The rat is anaesthetized with Xylazine Ketamine combination intravenously and was kept on an inverted polypropylene tray with its head down at 45° angle. A depressible surface which look like a rhomb between occipital protuberances and the spine of the atlas becomes noticeable. A butterfly needle attached to a syringe was introduced into the cisterna magna, and cerebrospinal fluid is aspirated. The method is non-invasive and doesn’t require any sophisticated equipment and lessens the chance of contamination of the sample with blood. The technique is also less time consuming and easy to perform.

The epidural blood patch (EBP) requires a syringe that connects to the intravenous and epidural route. Thereby contravening Department of Health guidance, which recommends adoption of equipment that, prevents wrong route drug administration. To comply with these recommendations a non-Luer butterfly needle with one-way valve has been produced by GBUK. The one-way valve and length of tubing has the potential of activating the clotting cascade. This could reduce the time clinicians have to utilise the blood in the syringe. Also any alteration in clotting could affect the therapeutic value of the EBP. The primary objective of this research was to determine if phlebotomy using this new 21G needle altered blood clotting, determined by thromboelastograph analysis, compared to a standard 21G hypodermic needle.We performed paired phlebotomy on 10 healthy volunteers; producing a study capable of revealing a 25% change in R-time (power 80%). Mean R-time was increased with the new needle, however remaining within normal range (7.3 vs 6.6 min (p=0.04)). This would not limit the time to utilise the blood before clot formation in the syringe. With no clinically relevant difference in MA or LY30, it is unlikely to have any impact on the therapeutic value of the EBP.
