Radiography can detect surgical needles as small as 17 mm. Mobile image intensifiers are recommended for optimal detection of lost surgical needles, improving patient safety post-procedure.

Area of Science:

  • Medical Imaging
  • Surgical Safety
  • Radiography

Background:

  • Surgical procedures frequently employ minuscule needles.
  • Incorrect postoperative needle counts necessitate radiographic localization.
  • Limited data exist on the smallest radiographically detectable needle and optimal imaging techniques.

Purpose of the Study:

  • To determine the smallest surgical needle visible with conventional radiography.
  • To identify the optimal radiographic technique for locating retained surgical needles.

Main Methods:

  • A quality assurance project involving radiographic imaging of various surgical needle sizes.
  • Observer assessment to determine visibility thresholds.
  • Evaluation of different radiographic techniques, including mobile image intensifiers.

Main Results:

  • The smallest surgical needle consistently identified by observers measured 17 mm.
  • Imaging with a mobile image intensifier was found to be the preferred technique for detecting lost needles.

Conclusions:

  • Surgical needles down to 17 mm are detectable via standard radiography.
  • Mobile image intensifiers offer superior detection capabilities for lost surgical needles, enhancing procedural safety.
