RESUMO
AIM: Cesarean section rates are increasing worldwide and Robson's classification system allows a practical approach to study this phenomenon. C-section in Chile has been indicated as unexpectedly high, with important variability within the country and payment systems. The aim was to report our data using Robson's system and the evolution of local C-section rate in a public hospital during a 9-year period. METHODS: Retrospective analysis (2005-April 2014), in a metropolitan hospital in Santiago. All deliveries were classified into Robson groups. Time changes were analyzed with Pearson's correlation. P value <0.05 was considered significant. A 'relevance index' (RI) for each group was calculated as 100 × C-S rate × relative contribution. RESULTS: The overall C-section rate increased from 24 to 27% (P < 0.05) in 53 571 deliveries, with a greater increase in groups 1 (nulliparous, single, term cephalic, spontaneous labor), 3 (multiparous, single, no previous C-S, term cephalic, spontaneous labor) and 4 (multiparous, single, no previous C-S, term cephalic, induced or no labor). Despite no increase in Group 5 (women with one or more previous C-S) this group had the highest RI (20.3), which defined priority for intervention over others. CONCLUSION: C-S rate was lower than that reported in other centers from Chile and Latin America. Robson's classification and the RI allowed prioritization. Although increase in groups 1, 3 and 4, group 5 needs attention because of stronger impact on overall C-S rate. This analysis allowed to define how to lower C-S rate in our institution.

Thoracoamniotic shunting in fetal pleural effusion has poor results, with an overall survival of less than 50% when hydrops is associated. Those cases without hydrops presented the best evolution, but the indication in these cases remains controversial. We present a dichorionic diamniotic twin pregnancy at 29 weeks' with right pleural effusion and hydrops, in which one fetus presented diaphragm inversion and mediastinal shift, both considered as ultrasonographic signs of thoracic hypertension. A thoracoamniotic shunt reversed these signs immediately. Nevertheless, 1 week after, these signs and skin edema reappeared and the effusion increased, leading to a second thoracocenthesis for drainage and intrathoracic pressure measurement. Amniotic fluid and intrathoracic pressures were found at 21 and 39 mm Hg, respectively. A cesarean section was performed and the catheter was found to be obliterated by cellular detritus of leukocytes and fibrin. Our conclusion is that ultrasonographic signs of elevated thoracic pressure are a keystone for the shunt indication, and that this could be corroborated by direct measurements. This can be an important parameter for precise indication of thoracoamniotic shunting.
