Propofol and midazolam provided effective sedation for transvaginal oocyte retrieval. Propofol offered faster onset and quicker recovery of cognitive function compared to midazolam.

Area of Science:

  • Anesthesiology
  • Reproductive Medicine

Background:

  • Transvaginal oocyte retrieval requires effective sedation for patient comfort and procedural success.
  • Patient-controlled analgesia (PCA) offers a method for titratable sedation during short procedures.

Purpose of the Study:

  • To compare the efficacy and recovery profiles of propofol versus midazolam administered via a modified PCA pump during transvaginal oocyte retrieval.

Main Methods:

  • A randomized study involving 47 patients undergoing transvaginal oocyte retrieval.
  • Patients received either propofol (3 mg/0.3 ml) or midazolam (0.1 mg/0.3 ml) via PCA, with alfentanil administered as needed.
  • Cognitive function was assessed using p-deletion, reaction time, and critical flicker fusion tests post-procedure.

Main Results:

Related Experiment Videos

  • Propofol demonstrated a significantly faster onset of sedation (70.6 s) compared to midazolam (106.3 s).
  • While both agents provided adequate sedation for procedure completion, propofol group showed no cognitive impairment at 30 minutes post-procedure, unlike the midazolam group.

Conclusions:

  • Modified PCA with propofol or midazolam is effective for transvaginal oocyte retrieval.
  • Propofol offers advantages in terms of faster sedation onset and quicker recovery of cognitive function compared to midazolam.
