Percutaneous Puncture of the Radial Artery with a Multi‐Purpose Teflon Catheter for Indwelling Use

Abstract

BARR, P.-0. Percutaneous puncture of the radial artery with a niultipurpose TeJon catheter for indwelling use. Acta physiol. scand. 196 1. 51. 343-347. -A Teflon catheter assembly is described, which was designed for percutaneous insertion and indwelling use in the radial artery, and in other superficial blood vessels with calibers of a similar order of magnitude. The advantages of the instrument, which may also be used for percutaneous puncture of other superficial tissues and organs, are reported and discussed, especially with regard to the preferential choice of the radial artery for arterial punctures.

Ultrasound guidance versus direct palpation for radial artery catheterization by expert operators: a randomized trial among Canadian cardiac anesthesiologists

“…Similarly, there was no significant difference between the DP and US groups in the median [IQR] number of attempts (1 [1-2] vs 1 [1-2], respectively; P = 0.08) and number of redirects (2 [0-6] vs 3 [1][2][3][4][5], respectively; P = 0.82). Firstattempt success rates were 56.4% in the DP group and 71.4% in the US group (difference between proportions, 15.0%; 95% CI, -1.9 to 31.8; P = 0.10).…”

“…Les critères d'évaluation secondaires comprenaient le nombre de tentatives d'insertion, de changements de direction de la sonde, ainsi que le taux d'échec. Résultats Aucune différence n'a été observée entre les groupes PD (n = 62) et EG (n = 63) en matière de temps médian [écart interquartile] jusqu'au positionnement (104 sec vs 104 [68-270] sec, respectivement; P = 0,66), du nombre de changements de direction de la sonde (2 [0-6] vs 3 [1][2][3][4][5], respectivement; P = 0,82), ou du nombre de tentatives (1 [1][2] vs 1 [1][2], respectivement; P = 0,08). Le taux de réussite à la première tentative était de 56,4 % dans le groupe PD et de 71,4 % dans le groupe EG (P = 0,10).…”

Dynamics of Arterial Oxygen Tension in Response to Sinusoidal Work Load in Man

“…rial oxygcn tension (Pa0,) was recorded continuously by a Clark-type microelectrode and 0, monitor (E506, and PHA927 Radiometer, Copenhagen). T h e Pao, recording system was similar to that used by Rosenhamer (1967) with a measuring chamber (volume = 0.2 ml) connected to the right or left radial artery by an indwelling Teflon catheter (Barr 1961) and interposed Teflon tubing (total length of tubing including catheter about 30 cm, I.D. = 0.9 mm).…”

Applications of Focused Cardiac Ultrasound (FoCUS) in Obstetrics

“…This practice has evolved over the last few decades with the hemodynamic parameters measured often having been dependent on available technology. Non-invasive observations of vital signs served as the only commonly used practice until the 1960s and 1970s when arterial and central venous pressure (CVP) waveform transduction became more commonly used, and in the 1980s with the introduction of pulmonary artery catheters (PACs) into clinical practice [1]. With concerns particularly regarding the limited outcome impact of employing PACs in clinical practice [2] and the greater focus on complications associated with invasive monitoring by oversight agencies, there has been a decline in the enthusiasm for using invasive monitoring in the critically ill parturient [3].…”
