[Fetal lesions due to the bistoury during cesarean section: a study of 58 cases. The 5-year case records of 3117 cesarean sections at the Institutes of Clinical Obstetrics and Gynecology of the University of Rome La Sapienza].

In the present article the authors have carried out a statistical investigation on data relative to the caesarean sections performed in the Departments of Obstetrics and Gynaecology of the University of Rome "La Sapienza" since 1986 to 1990. Particular object of this study is to evaluate data regarding fetal bistoury lesions incidentally caused while performing the incision of the uterine wall during a caesarean section. To our knowledge, this topic has never been taken into account by the world's literature, nevertheless it is important also for its legal and insurance implications. Throughout the mentioned period 13787 deliveries occurred, 3117 of which were caesarean sections: this is equal to a frequency of 22.6%, with an increase rate of 37.5% during the whole 5 years time. 58 cases of fetal bistoury lesions have been found to occur since 1986 to 1990: this equal to 1.8% of all the performed caesarean sections. Even if their gravity was usually scarce, and only 7 cases needed a specific treatment, 25.8% of these lesions involved areas such as forehead, cheek bone, cheek, mostly related to possible aesthetic damages with their connected legal consequences. In order to evaluate what factors can contribute to the occurrence of these lesions and taking account of the large number of factors that may be involved (such as conditions at which the operation is performed, skill and experience of the surgeon etc.), the authors focus their attention to those which, for their clinical significance and possibility of detection, suit more than others such a statistical investigation.(ABSTRACT TRUNCATED AT 250 WORDS)

[Trauma and pregnancy].

The medical care provided to a pregnant trauma patient by a trauma specialist should be supplemented by a careful evaluation of the pregnant woman by an obstetrician. Motor vehicle accidents account for two-thirds of all trauma events during pregnancy, and both blunt abdominal trauma and trauma to the skull are associated with high mortality of the fetus. The severity of the trauma is an important prognostic factor for survival of both mother and fetus. Fetal injury can be caused even by apparently mild forms of maternal trauma. For early diagnosis of an abruptio placentae after blunt trauma to the abdomen, continuous monitoring of the fetal heart rate and uterine contractions is very useful. Monitoring should be continued for at least 4 h, and whenever the frequency of uterine contractions exceeds one per 15 min or tenderness of the abdomen or vaginal bleeding is present, the pregnant trauma patient should be carefully monitored under hospital conditions for at least 24 h. Extensive burns are rarely encountered during pregnancy. There is a direct correlation between the extent of the burns and survival of the fetus. When more 30% of the maternal body surface is affected by burns, fetal mortality exceeds 50%. In the third trimester, when survival chances of the fetus are better than 50%, premature delivery of the fetus should be considered whenever the mother has suffered extensive burns.

Accidental incision of the fetus at caesarian section.

BACKGROUND: Caesarian section is the most common major surgical procedure among women of reproductive age. It is thought to be safer for the baby than the mother. However, the baby is at risk of laceration injury. METHODS: Retrospective review of clinical records of women who were delivered by caesarian section during a seven-year period from January 1, 1991 to December 31, 1997. RESULTS: Fetal laceration injury was documented in 0.55% of live caesarian section births. Accidental incision of the fetus was associated with emergency caesarian section, ruptured membranes and relative inexperience of the operating surgeon. Documentation of injury was poor and there was no evidence that parents were counselled. CONCLUSION: Laceration of the fetus is an occasional complication of caesarian section. Proper documentation and counselling of parents are required especially as there are potential medicolegal implications. Careful attention to the technique of uterine entry at caesarian section should reduce the risk of injury to the fetus.

Extensive brain injury in a premature infant following a relatively minor maternal motor vehicle accident with airbag deployment.

Traumatic injury following a motor vehicle accident during pregnancy has an enormous potential for fetal injury and demise. With the advent of seat belts, shoulder restraints and airbags, and improved maternal survival, the most common cause of fetal loss is placental injury. However, the safety of airbag deployment during pregnancy and in particular during the latter stages, and the potential for fetal trauma remains unclear. We report a case of extensive neurological injury of a premature infant with minimal maternal trauma associated with deployment of an airbag following a minor motor vehicle accident.

Fetal trauma: brain imaging in four neonates.

The purpose of this paper is to describe brain pathology in neonates after major traffic trauma in utero during the third trimester. Our patient cohort consisted of four neonates born by emergency cesarean section after car accident in the third trimester of pregnancy. The median gestational age ( n=4) was 36 weeks (range: 30-38). Immediate post-natal and follow-up brain imaging consisted of cranial ultrasound ( n=4), computed tomography (CT) ( n=1) and post-mortem magnetic resonance imaging (MRI) ( n=1). Pathology findings were correlated with the imaging findings ( n=3). Cranial ultrasound demonstrated a huge subarachnoidal hemorrhage ( n=1), subdural hematoma ( n=1), brain edema with inversion of the diastolic flow ( n=1) and severe ischemic changes ( n=1). In one case, CT demonstrated the presence and extension of the subarachnoidal hemorrhage, a parietal fracture and a limited intraventricular hemorrhage. Cerebellar hemorrhage and a small cerebral frontal contusion were seen on post-mortem MRI in a child with a major subarachnoidal hemorrhage on ultrasound. None of these four children survived (three children died within 2 days and one child died after 1 month). Blunt abdominal trauma during pregnancy can cause fetal cranial injury. In our cases, skull fracture, intracranial hemorrhage and hypoxic-ischemic encephalopathy were encountered.

Stress in pregnancy activates neurosteroid production in the fetal brain.

Neurosteroids such as allopregnanolone are potent agonists at the GABA(A) receptor and suppress the fetal CNS activity. These steroids are synthesized in the fetal brain either from cholesterol or from circulating precursors derived from the placenta. The concentrations of allopregnanolone are remarkably high in the fetal brain and rise further in response to acute hypoxic stress, induced by constriction of the umbilical cord. This response may result from the increased 5alpha-reductase and cytochrome P-450(SCC) expression in the brain. These observations suggest that the rise in neurosteroid concentrations in response to acute hypoxia may represent an endogenous protective mechanism that reduces excitotoxicity following hypoxic stress in the developing brain. In contrast to acute stress, chronic hypoxemia induces neurosteroidogenic enzyme expression without an increase in neurosteroid concentrations and, therefore, may pose a greater risk to the fetus. At birth, the allopregnanolone concentrations in the brain fall markedly, probably due to the loss of placental precursors; however, stressors, including hypoxia and endotoxin-induced inflammation, raise allopregnanolone concentrations in the newborn brain. This may protect the newborn brain from hypoxia-induced damage. However, the rise in allopregnanolone concentrations was also associated with increased sleep. This rise in sedative steroid levels may depress arousal and contribute to the risk of sudden infant death syndrome. Our recent findings indicate that acute hypoxic stress in pregnancy initiates a neurosteroid response that may protect the fetal brain from hypoxia-induced cell death, whereas the decline in allopregnanolone levels after birth may result in greater vulnerability to brain injury in neonates.

Abdominal trauma in the pregnant patient.

Physicians who care for pregnant women must be prepared to evaluate and treat abdominal trauma during pregnancy. The evaluation and management of even minimal abdominal trauma in pregnancy is often problematic, and the use of laboratory tests, fetal monitoring, radiography and ultrasonography depends on the extent of the trauma and the viability of the fetus. Intervention ranges from reassurance to cardiopulmonary resuscitation and surgery. Common laboratory studies include a complete blood count, coagulation panel, urinalysis and blood type and screen. Ultrasonography is useful for evaluation of fetal weight and status of amniotic fluid, but tocodynamometry is more sensitive for diagnosis of placental abruption. Patients with minimal trauma and no bleeding, uterine contractions or abdominal pain can be safely discharged after four to six hours of monitoring, but patients with any of these findings should be admitted to the hospital for overnight observation with continuous fetal heart rate monitoring.

[Trauma in the last trimester of pregnancy].

Although accidents during pregnancy are fairly rare, besides endangering the mother, they nearly always mean a vital threat to the fetus: lethality rates are up to 8% for the mother and up to 34% for the fetus. Besides depression of the circulatory system in the mother, coupled with fetal hypoxy, injury to the placenta and uterus is also possible. Moreover, the unborn child may be injured by direct trauma. If the fetus sustains a direct injury, the head of the child is affected in the majority of instances. In addition, the risk of an intrauterine death is very high. If the injured baby survives after a section, permanent damage must be taken into account. Pregnant women who are injured in an accident should quickly be checked by sonography and cardiotocography. If no danger is expected for the child, the usual therapeutic rules that apply for traumatology should be followed. If the mother and child are endangered, a cesarean section must be undertaken along with simultaneous accident-related surgery on the mother. Case reports are presented on three cases in our clinic last year, and the current literature is discussed. All three mothers and newborns survived because of the cooperation between surgeons, gynecologists and pediatricians.
