Purpose

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

Official Title:	CT Study of Atelectasis After Delivery - Comparison Between Cesarian Section and Labor

Further study details as provided by University of Sao Paulo:

Primary Outcome Measures:

atelectasis [ Time Frame: 60-120 minutes after delivery ] [ Designated as safety issue: No ]

Biospecimen Retention: None Retained

Biospecimen Description:

Enrollment:	20
Study Start Date:	July 2006
Study Completion Date:	November 2007

Groups/Cohorts	Assigned Interventions
PN Control - Induced or natural labor under anesthesia	Radiation: CT scan Thoracic CT scan
PC Case - Cesarean section under anesthesia	Radiation: CT scan Thoracic CT scan

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.
