This procedure can be done either with ultrasound identification of a safe pocket followed by blind needle insertion, or under real-time guidance using a technique similar to vascular access (see Chapter 3).
Try sitting the patient up slightly and rotating to move bowel out of the way. Scan in both short and long axis.
Safe pockets are frequently in the RLQ and LLQ. The midline is described as a reasonable target, but ...
