A comparative study between manual vacuum aspiration and electronic suction for surgical treatment of abortion

Background Present study is done to study the safety, efficacy and complications of using manual vacuum aspiration (MVA) for surgical management of first trimester abortion in comparison to electronic suction.

Methods It is a retrospective observational study conducted in department of obstetrics and gynecology at tertiary care hospital. Out of 100 cases taken, 50 abortions were terminated by MVA and 50 were terminated by electric suction/vacuum aspiration (EVA).

Results In this study, majority of the patients were primigravida (60%). Most of the patients had period of gestation between 7 to 9 weeks (40%) followed by up to 6 weeks (33%) in both groups. Time taken for the procedure was less in MVA (5-9 min.) than electronic suction (7-11 min.). In terms of complications, blood loss ≥100 ml was more with EVA (18%) compared to MVA (6%). Uterine perforation was seen with EVA (4%) and none with MVA. As far as success rate is concerned, EVA got 98% while MVA got 90%. Post-operative hospital stay was less with MVA (≤12 hours) than EVA (up to 24 hours). Post-operative pain perception was less with MVA (18% severe pain) while with EVA, 36% with severe pain.

Conclusions Both the evacuation techniques are almost equally effective and safe, still duration; post-operative pain and hospital stay are less with MVA. Success rate is better with EVA.
