Atelectasis During Delivery - Comparing Cesarian (c) -Section and Labor

Completed

• Conditions: Cesarean Section; Delivery, Obstetric; Labor; Respiration Disorders; Atelectasis
• Interventions: Radiation: CT scan

• Registration Number: NCT00665405
• Lead Sponsor: University of Sao Paulo

Brief Summary

Pregnancy promotes respiratory system's restrictive component. This study observes the generation of atelectasis during labor.

Detailed Description

Pregnancy causes restriction of diaphragm movements as well as higher resistive component to the respiratory system. Spirometry studies have shown that the supine position increases risks of hypoxemia. There seems to be only casual observation regarding the generation of atelectasis during labor.
