Anaesthesia · Complications: TURP irrigation fluid

Sample item

Which irrigating fluid is least likely to cause haemolysis if absorbed, and is used with monopolar TURP?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Glycine 1.5%

Glycine 1.5% is only mildly hypotonic (about 200 mOsm) and non-conducting so it is safe for monopolar diathermy, while distilled water causes haemolysis. Normal saline conducts current and is used in bipolar resection.

Option by option

  • A. Glycine 1.5% (correct)

    Correct. Glycine is commonly used for monopolar TURP.

  • B. 5% dextrose

    Dextrose is not used.

  • C. Distilled water

    Distilled water causes haemolysis.

  • D. Normal saline

    Saline conducts current and disperses the monopolar current.
