Objective: The objective of this study was to observe the efficacy of manual vacuum aspiration (MVA) and electrical suction/vacuum aspiration (EVA) for pregnancy termination and to compare the two techniques. Methodology: A prospective study of 200 cases of medical termination of unwanted pregnancy in first trimester was done by applying MVA and EVA at Gauhati Medical College and Hospital. Results: In this study majority of patients belonged to age group 26 - 30 years, Hindu religion and middle class. Maximum women were educated up to high school. Most of the patients had period of gestation between 6 to 8 weeks (44%) followed by up to 6 weeks (36%) in both the groups. Average blood loss in MVA was 33.9 ml and that of EVA 85.45 ml. Blood loss in both the groups increased with increasing gestational age. Average time taken was 11.77 and 16.55 minutes in MVA and EVA respectively. In terms of complication, no major complication was found except in 9% of cases MVA failed and had to be converted to EVA for complete evacuation. At postoperative period, mild bleeding (grade II) was seen in 22% cases mostly in patients of EVA group. As far as success rate is concerned, EVA got 100% while MVA got 91%. Conclusion: Both the techniques were found to be almost equally effective. Though blood loss is slightly lesser in MVA but success rate in term of complete evacuation is better in EVA.
