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

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.
