The aim of this study was 550 patients with preterm labor (mean, 91.5%) hospitalized for termination of pregnancy at 8-10 weeks (mean, 10.7 weeks), 25 years of age (mean, 25.6 years). Different PG analogues, different treatment times and different doses of 0.5 mg or 1 mg of methyl PGF 2α methyl ester for 3 hours, 1.0 mg 16,16 double methyl trans △ ~ 2 PGE 1 Methyl ester 3, 6 or 12 hours, 30 mg 9 deoxy 16,16 bismethyl 9 methyl PGE 2, 6 or 12 hours, 0.25 mg 16 phenyl omega-17, 18, 19, 20 tetranor PGE2 A Sulfamide for 3 hours or 0.5 mg of the same complex for 3 and 12 hours. In addition to 16 phenyl ω-17,18,19,20 tetranucleoside PGE_2 methylsulfamide intramuscular injection, Yu were suppositories into the vagina or into a medium coarse seaweed bar 3 hours, then do suction Palace surgery.
