 :: Abstract 

A combination of 100 ml of 0.1% Ethacridine lactate solution and two intra-muscular injections of prostaglandin (300 µg each of I5-Methyl-PGF 2α)was tried for safe termination of pregnancy. It was found that the success rate (88%) with this combination regimen was better than ethacridine lactate alone but a little inferior to prostaglandins alone. Average abortion interval was also less than with ethacridine lactate. However, the combination did not reduce the gastro-intestinal disturbances associated with prostaglandins.

 :: Introduction Top

Ethacridine lactate (0.1%) used extra­amniotically has been shown to success­fully terminate pregnancy in about 75% [2] of the cases.

Prostaglandins as intramuscular injec­tion have shown high success rate and short. induction abortion interval, [1] com­pared to other abortifacients, but their restricted availability and high cost limits its frequent use. Hence we have attempt­ed to study the augmentary effect of intramuscular injections of prostaglan­dins in two small doses, on the clinical course of ethacridine lactate. The rationale of this trial was to evolve a method which is safe and is relatively cheaper than prostaglandins alone, with abortion time shorter and success rate higher than that of ethacridine lactate alone.

 :: Material And Methods Top

50 women in the age group of 15-35 years and between 13-20 weeks of gesta­tion were selected for this trial.

A Foley's catheter (No. 14F for nulli­parous and 16F for multiparous) was passed extra-amniotically. The bulb of the catheter was inflated with 30 cc of normal saline.

Initially, 100 ml. of 0.1% ethacridine lactate was instilled in all cases. Later at 3hourly interval, 300 µgm of 15-methyl. PGF 2α was given intramuscularly for 2 doses. The catheter was deflated and re­moved 6˝ hours from initiation of the therapy.

All patients were covered with long acting penicillin 1.2 mega units intra­muscularly.

 :: Results Top

[Table 1] shows the case distribution with respect to gestation weeks. 80% of the cases were in the early mid trimester group.

[Table 2] shows that majority (60%) of the cases were primigravidae, of which 93.3% were unmarried.

In [Table 3] we compare the clinical events of our present trial with that of intramuscular prostaglandins (as report­ed by Gharse et al [1] ) and ethacridine lactate (as reported by Purandare et al [2] ).

We find that the two intramuscular injections of prostaglandin have not only improved the rate of success from 75 (group I) to 88% (group III) but also shortened the abortion interval from 29.54 hours (group I) to 21.26 hours (group III). The incidence of incomplete abortion is only 8% in group III compar­ed to 16% and 48% in groups I and II respectively.

It is surprising that limiting the num­ber of intramuscular injections of prosta­glandins to two, did not appreciably re­duce the gastro-intestinal disturbances associated with prostaglandins.

 :: Discussion Top

Extra-amniotic injection of 0.1% etha­cridine lactate has been shown to suc­cessfully induce abortion in 75% of the cases with an average induction abortion time of 30 hours [2] (approximately).

Prostaglandins in multiple intramus­cular doses were shown to be successful in 97.8% of the cases with an average induction abortion time of 18.18 hours [1] .

When two shots of intramuscular pro­staglandins have been used with etha­cridine lactate the average induction abortion time of ethacridine lactate is decreased to 21.26 hours and the net suc­cess is increased to 88%.
