A series of 12 trials of scar associated with scar rupture is reviewed. Uterine activity patterns were assessable in 10 of them. Clinical features and characteristics of the intrauterine pressure waveform and uterine activity are discussed in relation to the integrity of the scar.

A case is reported of rupture of the uterus after intraamniotic injection of prostaglandin F2 alpha followed by intravenous oxytocin. The literature is reviewed and the management discussed.. A 34-year old Puerto Rican woman gravida 8, para 5, abortions 1, miscarriage 1, living children 4 admitted to the New York Hospital-Cornell Medical Center for prostaglandin abortion had a delayed diagnosis of rupture of the left uterine artery. The delay in diagnosis was attributed to the intraligamentous and retroperitoneal location of the hematoma. The bleeding was controlled by performing a supracervical hysterectomy and ligation of the left hypogastric artery. The patient recovered uneventfully. Rupture of the uterus is a less common occurence than cervical lacerations, which occur in 1% to 2% of 2nd trimester abortions and most frequently among young primigravidas. Uterine rupture occurs mostly in multiparous women and does not appear to be prevented by laminaria tents. Uterine rupture at term following oxytocin induction has been related with multiparous patients. Uterine rupture has also ben observed following induction of midtrimester abortion with intraamniotic hypertonic saline or prostaglandin analogs, and the dilatation and evacuation method. Of 12 documented cases of uterine ruptures after saline/prostaglandin-induced abortion, 11 necessitated hysterectomy and 2 patients died from blood loss. Management of oxytocin and prostaglandin-induced abortion is briefly discussed.

A very unusual observation of survival after surgical treatment of neonatal maceration of liver and spleen is reported. The patient had a normal birthweight and the only possible etiologic factor was a oxitocin-induced rapid delivery. The literature on this topic is reviewed.

A study was made of the characteristics of oxytocin-induced labour. Twelve patients with, and eight without membrane rupture were closely matched for factors likely to influence the character and duration of labour. In both groups uterine activity increased until a stable state was achieved loowing which there was little alteration until delviery. The duration of labour was shorten in the group with ruptured membranes as compared with intact membranes although, paradoxically, the uterineactivity tended to be greater when the membranes were intact.

This letter comments on a previously published article (August 17, p. 428) relating to the use of prostaglandins for midtrimester abortion. It is estimated that prostaglandin PGF-2-alpha given by the i ntrauterine route has been used in over 5000 patients; 13 cases of cervi cal rupture have been reported. Most ruptrues have occurred in primigravidae. All but 1 of them (who received PGE-2) were given PGF-2-alpha intraamniotically. Periods of gestation have been 15-22 weeks. Large doses of prostaglandins have been used and often supplemented by other oxytocics such as urea or oxytocin. No reported cervical ruptures have followed use of PGE-2 alone, possibly because of its relaxant effect on the cervix. Previous gradual dilatation of the cervix with laminaria tents or with some synthetic prostaglandin analogue is being studied. In first trimester pregnancies prostaglandin analogues given as a single extraamniotic dose 12 or more hours prior to termination has been shown to effect gradual dilatation of the cervix. Of 88 such cases, only 3 required mechanical dilatation of the cervix. It is felt that prostaglandins offer an attractive alternative to hysterotomy or hypertonic saline for terminating second trimester pregnancies when overstimulation of the uterus by large doses is avoided.

8 nulliparous women, all approximately 15 weeks pregnant, were administered 350 ml Macrodex intraamniotically during a period of 15-30 minutes to increase uterine volume. 4 of the patients aborted following a decrease in plasma progesterone and an increase in resting pressure, active pressure, and oxytocin response. In 2 patients, plasma progesterone increased while resting pressure, active pressure, and oxytocin response did not increase, and pregnancy continued undisturbed. It is concluded that increasing uterine volume may induce a compensatory synthesis of progesterone in the palcenta provided that: 1) the osmotic action of the injected hypertonic solution does not suppress placental function to a degree equal to that of the stimulatory effect of increasing volume; 2) the osmotic increase in volume is slow enough to permit the time-dependent increase in progesteronegenesis; and 3) the increase in intrauterine pressure and clinical progress in abortion does not suppress placental endocrine function. Further experiments are necessary to verify this interpretation.
