Inclusion criteria for this segment of the study were (a) admission to one of five critical care units in a Midwestern medical center, (b) orders for a blind insertion
of a small-bore feeding tube, (c) orders to start continuous feedings, and (d) radiographic confirmation of tube site before feedings were started.
The objective of this present study was to evaluate the effectiveness of ultrasound (US) guided radial artery cannulation as compared to the blind insertion
of arterial line in intensive care unit of a tertiary care center.
of a GEB, routinely used to guide endotracheal intubation, has resulted in perforation of the pharyngeal wall (9) but insertion using a laryngoscope to visualise the oesophageal opening has not resulted in any trauma (1).
It also gives access to esophagus allowing blind insertion
of oro-gastric tube in any position of the patient.
