Hypothermia is common during percutaneous nephrolithotomy (PNL). Temperature drops significantly during preparation and surgery, with females experiencing greater declines. Maintaining core body temperature is crucial.

Area of Science:

  • Urology
  • Anesthesiology
  • Patient Safety

Background:

  • Perioperative hypothermia is a concern in surgical procedures.
  • Percutaneous nephrolithotomy (PNL) involves potential risks including temperature changes.
  • Identifying risk factors for hypothermia during PNL is essential for patient care.

Purpose of the Study:

  • To quantify the core body temperature drop during percutaneous nephrolithotomy (PNL).
  • To identify patient-specific factors associated with increased risk of hypothermia during PNL.
  • To understand the timing and magnitude of temperature changes throughout the PNL procedure.

Main Methods:

  • Retrospective review of 77 patients undergoing 95 PNL procedures.
  • Core body temperatures monitored using esophageal thermistor probes.

  • Analysis of temperature changes from pre-operation through post-operation.

    • Main Results:

    • Mean core body temperature decreased by 0.9°C pre-procedure and an additional 1.0°C during PNL.
    • Temperature drop during PNL correlated with procedure length.
    • Female patients showed a significantly greater temperature decline than males; obese patients maintained temperature better.

    Conclusions:

    • Hypothermia is prevalent in the majority of patients undergoing PNL.
    • Significant temperature decreases occur during both pre-surgical preparation and the surgical phase.
    • Interventions to maintain core body temperature before and during PNL may mitigate hypothermia and its complications.
