Incidence of Respiratory Depression in Cesarean Section

A Prospective, Observational, Double-blind (Black-Box) Study Evaluating Incidence, Severity and Predictive Factors of Respiratory Depression During Postoperative Neuraxial Opioid Analgesia in Obstetric Patients After Cesarean Delivery Using Current Standard Intermittent Postoperative Monitoring Compared to Continuous Pulse Oximetry / Capnography

This study is designed to determine the incidence and severity of respiratory depression in elective cesarean section patients who have received a spinal or epidural narcotic called duramorph for management of postoperative pain. A monitoring device called a capnograph as well as a device called a pulse oximeter is placed on the patient once in the recovery room after delivery. The capnograph monitors the carbon dioxide level that the patient breathes out as well as their respiratory rate. The pulse oximeter is a device that is taped on the patient's finger and measures their oxygen saturation level. The monitoring is maintained for 18-24 hours after surgery.

Inclusion Criteria:

• Are female >= 18 years of age and <=55 years of age with ASA class I-III
• Schedule for cesarean surgery
• Are willing and able to sign informed consent form for this study
• Are willing and able to follow the instruction in this study protocol

Exclusion Criteria:

• Have known contraindication/allergy to neuraxial anesthesia or morphine.
• Have an ASA class > III
• Age > 55 years
