[Bilateral tubal occlusion by postpartum mini-laparotomy under local anesthesia and sedation]. / Oclusión tubaria bilateral por minilaparotomía post parto con sedación y anestesia local.

ABSTRACT

PIP: The first 1000 postpartum tubal occlusions by minilaparotomy under sedation and local anesthesia performed at a Mexican Institute of Social Security hospital in Mexico City were retrospectively reviewed. The operations took place between December 1990 and October 1991. The youngest patient was 17 and five patients were under 20. 52.3% were aged 20-29, 31.9% were aged 30-34, and 13.8% were aged 35-40. 65% of the women had three or four live births and 16.8% had two. The diastolic blood pressure was between 81 and 90 for 12.1%, between 91 and 100 for 8.9%, and between 101 and 120 for 3.7%. 19.7% had hemoglobin levels below 10 g. 37 women with hemoglobin levels between 4 and 8 g were sterilized; all received transfusions before discharge. 66.7% of the women weighed between 50 and 70 kg, but 2.3% weighed 100-120 kg. 40.6% used IUDs, 16.8% oral contraceptives, and 14.2% injectable methods. 24.8% had never used a contraceptive method. The Pomeroy technique was used in all cases. All patients were given Lidocaine. The operation was performed within 12 hours of delivery in 92.8% of cases. 96.3% of the women were discharged within 24 hours. Bleeding, resulting from tearing of the mesosalpinx, occurred in 0.8% of cases. A hematoma or abscess at the site of the incision was observed in 0.5% at one week follow-up. The data indicate that bilateral tubal occlusion by postpartum minilaparotomy under local anesthesia and sedation, rather than general anesthesia, is a rapid and safe procedure, even for obese and hypertensive women.
