Patient Experience with Conscious Sedation as a Method of Pain Relief for Transvaginal Oocyte Retrieval: A Cross Sectional Study

Abstract

Aim: The aim of the study was to measure patient's satisfaction level and acceptance of conscious sedation as a method of pain relief following transvaginal oocyte retrieval (TVOR) during assisted reproduction technology treatment. We also evaluated the factors that may influence the efficacy of conscious sedation method.

Setting and design: A prospective cross-sectional study.

Materials and methods: Prospective study was conducted from October 2015 to January 2016 at a university-level hospital and 100 women were recruited. Variables for analysis included woman age, duration of procedure, number of oocytes retrieved, and transmyometrial passage of the needle. Pain assessment was done by visual analog scale (VAS). Medical complications, and patient satisfaction score [Likert's score and client satisfaction questionnaire (CSQ)] were recorded.

Results: There was a moderate positive correlation between age and pain score on day 1 post-procedure. When the duration of procedure was >12 min, immediate post-procedure pain score was significantly higher compared to those whose procedure where duration was <12 min. There was no correlation between pain score and the number of oocytes retrieved (≤5, 6-15, and ≥16) and transmyometrial passage of needle. The VAS 10-point score immediately post-procedure, after 6 and 24 h post-procedure, and on day of embryo transfer was 2.83 (±1.67), 0.78 (±1.04), 0.39 (±1.09), and 0.14 (±0.58), respectively. The Likert's score was 3.65 (±0.82) and mean CSQ was 27.04 (±3.01). Majority of the women (86%) preferred the same pain relief method for future analgesia. There were no major complications.

Conclusion: Conscious sedation was associated with high satisfaction level and acceptance rate among patients undergoing TVOR.
