Sepsis and non-septic shock in pregnancy show characteristic modifications which are caused a) by physiologic changes in hemostasis primarily in the third trimester of pregnancy, b) by etiologic distinctions of shock regarded as pregnancy-specific, c) by hemodynamic changes in the circulation during pregnancy, d) by the ability of the healthy, young organism to compensate adequately. In the dead fetus syndrome and in non-septic shock, i.e., in amnionic fluid embolism and in abruptio placentae, the clinical picture is often governed by marked secundary fibrinolysis. Retroplacental hematoma, the characteristic feature of premature placental separation, remains controversial as either the cause or sequela of the hemostatic disorder. Etiologic, pathogenetic, and morphologic similarities exist between septic abortion, chorioamnionitis, and puerperal sepsis, but the varying response of the maternal organism during the course of pregnancy leads to different clinical and morphologic pictures. Due to a decrease in fibrinolytic activity as a consequence of pregnancy, the hypercoagulability state in a septic endotoxic shock predisposes the kidneys to bilateral renal cortical necrosis, principally in the amnion infection syndrome.

The DIC syndrome is the most common cause of an abnormal hemorrhage tendency during pregnancy and the puerperium and reflects systemic activation of the coagulation cascade by circulating thromboplastic material, with secondary activation of the fibrinolytic system. Its presence in a pregnant patient almost invariably is evidence of an underlying obstetric disorder such as abruptio placentae, eclampsia, retention of a dead fetus, amniotic fluid embolism, placental retention or bacterial sepsis. Diagnosis of the DIC syndrome rests on the demonstration of reduced levels of fibrinogen and platelets, prolongation of the thrombin, prothrombin and partial thromboplastin times, and the presence of fibrin/fibrinogen degradation products (FDP) in the serum. Therapy consists of prompt removal of the source of procoagulant material, replacement of depleted clotting factors and, in some cases, anti-coagulation with heparin.

The study was conducted on 350 babies born by caesarean section. There were 29 perinatal deaths among 350 births giving a gross perinatal mortality rate of 8.3 per 1000 live births. Corrected perinatal mortality rate was 7.1%. The stillbirth rate was 2%. It was high for cases of abruptio placentae, transverse lie and cord prolapse. Septicaemia was the commonest cause of perinatal death followed by asphyxia and prematurity. Birth weight played an important role in the survival of babies. There was no foetal loss among babies in weight group of 3501-4000 g. Perinatal morbidity was mainly due to asphyxia, septicaemia, prematurity and cord infection.

Incidence, risk factors and morphological features of the intravascular coagulation (IC) in 160 women who had died during pregnancy, after abortion and delivery were studied. IC was established in 118 (73.8%) of them. The main risk factors leading to IC were shock (59.3%), sepsis (28.8%), toxemia of pregnancy (incl. eclampsia) (25.4%), Caesarean section (19.5%), fetal death in utero (12.7%), amniotic fluid embolism (9.3%), and abruptio placentae (7.6%). Disseminated intravascular coagulation (DIC) was established in 66% of the cases, and local intravascular coagulation (univisceral localisation of microthrombi) in 28%. In the resting 6% of the cases there was consumptive coagulopathy without microthrombi. Lungs, pituitary gland, uterus, kidneys and adrenals were the most frequently affected organs. Necrosis in the parenchymal organs, hyaline membrane formation in the lungs and consumptive coagulopathy were particularly frequent in the cases with DIC. The leading causes of death were acute renal failure and ARDS. It was established that prolonged intensive care including artificial ventilation, massive blood transfusion, as well as surgical treatment, aggravate the course and morphological features of IC.

The purpose of this clinical investigation was to determine the maternal and perinatal results of continuing pregnancy in 118 consecutive patients with premature rupture of the membranes at 16 to 26 weeks. The mean gestational age at diagnosis of premature rupture of the membranes was 23.1 +/- 2.7 weeks, with a median of 23.5. The interval from rupture to delivery ranged from 1 to 152 days, with a mean of 13. There was no correlation between gestational age at the time of rupture and the latency period. Thirty-five patients received tocolytic agents and 24 received steroids. Forty-eight percent were delivered within 3 days, 67% within 1 week, and 83% within 2 weeks. There was one maternal death from sepsis; 46 (39%) had amnionitis, and 8 (6.8%) had abruptio placentae. The mean gestational age at the time of delivery was 24.7 +/- 3.6 weeks. The 118 pregnancies resulted in 124 births. There were 17 stillbirths and 67 neonatal deaths, for a total perinatal mortality of 67.7%. In patients with premature rupture of the membranes at less than or equal to 23 weeks the perinatal survival rate was 13.3%, while it was 50% in patients with premature rupture of the membranes at 24 to 26 weeks (p less than 0.0001). Information was charted at 3 to 36 months for 34 of 40 surviving infants. The intact survival rate in this group was 67%, and 33% had some form of developmental abnormality. Expectant management in such cases can be justified in only a limited number of patients (patients who understand and accept the risks and patients beyond 23 weeks of gestation).

During approximately a 9-year period, 37 severe preeclamptic-eclamptic patients had pulmonary edema for an incidence of 2.9%. The incidence was significantly higher in older patients (p less than 0.0001) and in multigravid patients (p less than 0.05). Eleven (30%) had antepartum edema with 10 (90%) of the 11 having preexisting chronic hypertension. Twenty-six (70%) had postpartum edema with an average onset of 71 hours post partum. The majority of these patients had excessive colloid and crystalloid infusions for various medical, surgical, and obstetric complications. There were four maternal deaths and morbidity was significant. Eighteen patients had disseminated intravascular coagulopathy, 17 had sepsis, 12 had abruptio placentae, 10 had acute renal failure, six had hypertensive crisis, five had cardiopulmonary arrest, two had rupture of the liver, and two had ischemic cerebral damage. The overall perinatal mortality was 530/1000 and neonatal morbidity was significant. Pulmonary edema is infrequent in severe preeclampsia-eclampsia without associated medical, surgical and obstetric complications. The occurrence of pulmonary edema in such patients is associated with high maternal and perinatal mortality and morbidity.

During 1978-1983, 57 maternal deaths (23 in blacks, 32 in coloureds and 2 in whites) occurred among 131,288 deliveries (36,564 in blacks, 89,335 in coloureds and 5389 in whites) in the Peninsula Maternal and Neonatal Service, Cape Town. Data for whites were not analysed further. Maternal mortality rates (MMRs) were higher in blacks than in coloureds. Age- and parity-specific MMRs showed that black teenagers and primiparas and coloureds aged 20-34 years and of parity 2-4 had the lowest rates. Advanced age and grand multiparity had a much greater adverse effect in coloureds than in blacks. Eighteen per cent of deaths in blacks and 9% of those in coloureds were in unbooked patients. The main causes of death (obstetric and non-obstetric) in blacks were sepsis, abruptio placentae, eclampsia and pneumonia. In coloureds they were eclampsia, other manifestations of proteinuric hypertension, cardiac disease, sepsis, haemorrhage (grouped) and diabetes. Of those who died, 43% of blacks and 38% of coloureds had had a caesarean section. The perinatal mortality rate was 417 for blacks and 469 for coloureds. A number of avoidable factors were identified. Most, if not all, deaths occurred because simple perinatal rules were broken.

The authors undertook a case-control study of 113 cases of neonatal sepsis and 347 randomly selected controls. All cases and controls were selected from the 1980 and 1981 Washington State birth certificates. The increased risk for males (odds ratio (OR) = 1.75, p = 0.012) and the large risk associated with low birth weight (OR = 99.1, p less than 0.001 if less than 1,500 g and OR = 5.17, p less than 0.001 if 1,500-2,500 g) are consistent with past studies. The relationship of maternal age (OR = 2.00, p = 0.01 if less than or equal to 20 years and OR = 1.74, p = 0.05 if greater than 30) parallels the overall risk of many pregnancy-related complications in these age groups. Interpretation of the elevated risk associated with amniocentesis is hampered by small numbers but is provocative. The strong association of an Apgar score of 6 or less at five minutes (OR = 36.25, p less than 0.001) with neonatal sepsis suggests the possibility of routine sepsis evaluation in such neonates born in areas with high incidence rates of early neonatal sepsis. We found no previous reports associating either abruptio placentae (OR = 12.70, p = 0.028) or preeclampsia (OR = 6.43, p = 0.017) with neonatal sepsis.

Between the 1st July 1990 and the 30th June 1995, 34 caesarean hysterectomies and 2708 (22%) caesarean sections were performed from 12,227 births on the I. Department of Obstetrics and Gynaecology Semmelweis University Medical School in Budapest. From all 34 cases, hysterectomy were performed in 9 cases (26%) after complicated delivery, in other 9 cases (26%) during elective caesarean section and in 16 cases (47%) during urgent caesarean section. The incidence of caesarean hysterectomy is 2.7/1000 labour in our study. We listed the placenta increta, placenta accreta, placenta adherens, placenta praevia, uteroplacental apoplexia, scar disruption, uterus rupture, atony, sepsis puerperalis, abruptio placentae, haematoma paravaginale as urgent indications and so elective indications were myoma uteri, cervical carcinoma, ovarial tumour and in-situ cervical carcinoma. We collect the elective and urgent indications of caesarean hysterectomy and summarize the possible operative and postoperative complications in our study.

1.286 patients were diagnosed as DIC, among 123.231 patients who were admitted in the 285 departments of the university hospitals in Japan, in 1992. The incidence of DIC was high in acute promyelocytic leukemia, fulminant hepatitis, abruptio placentae, acute respiratory distress syndrome, and sepsis. In cases of DIC, bleeding tendency due to consumption coagulopathy is most important, but organ dysfunction due to circulatory disturbances by development of multiple thrombi is also noteworthy. As a whole, DIC may be divided in two types. The first type is cases of DIC with severe bleeding symptoms. However, except cerebral hemorrhage, organ dysfunction is rare in these cases. These cases may be called as "fibrinolysis-dominant DIC", because hemostatic thrombi as well as thrombi which cause organ dysfunction by circulatory disturbances are rapidly removed by abnormally enhanced fibrinolysis. The second type involves cases of DIC with severe organ dysfunction. Bleeding symptoms in these cases are usually not severe. These cases may be called as "coagulation-dominant DIC". The most typical causative disease of the fibrinolysis-dominant DIC is acute promyelocytic leukemia. The most typical causative disease of the coagulation-dominant DIC is sepsis. The presence of causative disease of DIC, elevation of FDP, and depletion of platelet count are most important to diagnose DIC. In the treatment of DIC, removal of cause of DIC, administration of heparin to protect further development of multiple thrombi, and replacement of platelets in cases of acute leukemia are most important.
