Comparison of assisted reproductive technology performance after oocyte retrieval under general anaesthesia (propofol) versus paracervical local anaesthetic black: a case-controlled study

Propofol (Dipirivan(R)) is an intravenous anaesthetic drug used for general anaesthesia, Although frequently used as a general anaesthetic for ultrasound procedures, its use during transvaginal oocyte retrieval is currently being debated. A total of 202 patients undergoing fertility treatment was included in a prospective, matched, controlled study, in which we compared fertilization rates and embryo development in terms of morphological quality and speed of development and the implications for reproductive outcome and pregnancy following general anaesthesia using either propofol or a paracervical local anaesthetic block during oocyte collection. There were no differences between the fertilization rates and the embryo cleavage characteristics for the two groups. The initial implantation rate per transferred embryo after general anaesthesia was similar to that after paracervical local anaesthetic block (13.4 versus 18.6%; P = 0.10), The ongoing clinical implantation rates per embryo transferred were also similar in the two groups.
