Randomized Controlled Trial
Verification of intravenous catheter placement by auscultation--a simple, noninvasive technique.
Verification of proper placement of an intravenous catheter may not always be simple. We evaluated the auscultation technique for this purpose. ⋯ Being simple, handy and noninvasive, we recommend to use the auscultation technique for verification of the proper placement of an intravenous catheter when uncertain of its position. Data obtained in our limited sample of healthy subjects need to be confirmed in the clinical setting.

A long-term tunneled hemodialysis catheter can be difficult or impossible to pull out if a fibrin sleeve has attached it to the venous wall. We report the outcome of a refinement of Hong's technique for removing incarcerated catheters aimed at improving its feasibility and safety. ⋯ Hong's technique was confirmed to be a simple, safe and highly effective way to remove incarcerated long-term central venous catheters. The refinements we adopted made the procedure more flexible and possibly less prone to complications. By properly using ordinary tools available anywhere, Hong's technique could be considered Columbus' egg in this previously risky field.

The aim of this study is to examine the efficacy of normal saline (0.9% sodium chloride) as a flush solution on patency of arterial lines in comparison to heparin flush. Data have been examined in various categories of specialty (medical, surgical, cardiac, burns, gynecology), frequency of flushes, strength and volume of flushes, continuous versus bolus, duration of each flush and patency incidence (range, ≤ 24 to ≥ 96 hours). The secondary aim focused on the incidences of reported heparin-induced thrombocytopenia (HIT type I and II). ⋯ There is level 1 evidence to support heparin as a flush solution once the time frame exceeds 48 hours. In addition, there is level 1 evidence to suggest that heparin at higher doses and in continuous infusion has better patency incidence with no reports of HIT type II or I.
