Preoperative fasting guidelines often ignore evidence supporting fluid intake up to 3 hours before surgery. Studies show patient thirst causes more discomfort than not eating, sleeping, or surgical anxiety, urging a practice change.

Area of Science:

  • Medical Research
  • Surgical Patient Care
  • Nursing Practice

Background:

  • Current institutional policies often mandate nil per os (nothing by mouth) after midnight for surgery patients.
  • Existing research indicates that allowing fluids up to three hours before elective surgery is safe for most patients.
  • This practice contradicts evidence-based recommendations and patient comfort.

Purpose of the Study:

  • To investigate patient perceptions of discomfort associated with preoperative thirst.
  • To compare the discomfort of thirst with other preoperative stressors like hunger, sleep deprivation, and surgical anxiety.
  • To provide evidence supporting a revision of preoperative fluid restriction policies.

Main Methods:

  • A study was conducted with 50 elective surgery patients.

  • Patients' perceptions of discomfort related to thirst were systematically documented.
  • Discomfort levels were compared to those associated with fasting, lack of sleep, and surgical worries.

    • Main Results:

    • Thirst was identified as a significant source of patient discomfort.
    • The discomfort caused by thirst was perceived as greater than the inability to eat or sleep.
    • Thirst-related discomfort exceeded anxiety about the surgical procedure itself.

    Conclusions:

    • Preoperative thirst significantly impacts patient well-being and comfort.
    • Current NPO (nothing by mouth) after midnight policies may cause unnecessary patient distress.
    • Nurses should advocate for policy changes to align preoperative fluid restriction with current evidence and patient comfort.
