BACKGROUND AND OBJECTIVES There are different ultrasound probe positions used for internal jugular venous catheter placement. Also, in-plane or out of plane needle approach may be used for catheterization. Transverse short-axis classic approach is the most popular performed approach in literature. "Syringe-Free" is a new described technique that is performed with oblique long-axis approach. We ...

Figure 4 4) Constant force on the plunger that automatically depresses when the epidural needle enters the epidural space eliminates the subjective “feel” required with standard LOR syringes. 5) Air Vs Saline: As no subjective feel is required, technically saline is as good as air. Thus by avoiding air complications related to it like, patchy block, risk of venous air embolism can be avoided. 6...

Sin Nombre virus (SNV) and Andes virus (ANDV) cause most of the hantavirus pulmonary syndrome (HPS) cases in North and South America, respectively. The chances of a patient surviving HPS are only two in three. Previously, we demonstrated that SNV and ANDV DNA vaccines encoding the virus envelope glycoproteins elicit high-titer neutralizing antibodies in laboratory animals, and (for ANDV) in non...

STUDY OBJECTIVE To compare the diagnostic sensitivity of a modified Abrams needle pleural biopsy technique (A1) with the standard Abrams (A2) and Cope needle biopsy methods. The modified Abrams pleural biopsy technique consisted of suctioning each tissue sample into a syringe without removing the needle completely from the chest until the completion of the entire procedure. Both the standard Ab...

This study aimed to evaluate the diagnostic utility of Fine Needle Aspiration Cytology (FNAC) in evaluation neoplastic cutaneous nodular skin lesions and provide insights from a tertiary care institute. A total 150 patients with were included study, FNAC was performed using 23-gauge needle attached 10-ml syringe. The found that is valuable tool for lesions. It had sensitivity 88% specificity 10...

PURPOSE Presently, no standardized technique exists to monitor injection pressures during peripheral nerve blocks. Our objective was to determine if a compressed air injection technique, using an in vitro model based on Boyle's law and typical regional anesthesia equipment, could consistently maintain injection pressures below a 1293 mmHg level associated with clinically significant nerve injur...

BACKGROUND Multiple factors impact subcutaneous insulin injection pain. Injection devices [e.g., syringe or pen needle (PN)] affect pain due to needle length, diameter, needle polishing and lubrication, and needle tip geometry. METHODS We evaluated a modified 5-bevel PN tip in 32 G × 4 mm 31 G × 5 mm and 8 mm PNs vs the equivalent marketed 3-bevel PNs in laboratory penetration force testing, ...

The dataset developed consists of 108 blood drip stains developed with fresh porcine blood, blood admixed with different dosage of Warfarin and Heparin, respectively. For each particular blood type (i.e. fresh blood, blood admixed with Warfarin at different dosage and blood admixed with Heparin at varied dosage) stain patterns were created by passive dripping of blood from a 2.5 cm(3) subcutane...

OBJECTIVE In this work we set to develop and to validate a new in vivo frameless orthotopic Diffuse Intrinsic Pontine Glioma (DIPG) model based in the implantation of a guide-screw system. METHODS It consisted of a guide-screw also called bolt, a Hamilton syringe with a 26-gauge needle and an insulin-like 15-gauge needle. The guide screw is 2.6 mm in length and harbors a 0.5 mm central hole w...
