Objective:
The purpose of this study was to investigate whether supplemental oxygen during and for 2 hours after cesarean delivery reduces the incidence of postcesarean infectious morbidity.
Study Design:
We conducted a randomized, controlled trial from 2008-2010. Women who underwent cesarean delivery were randomly assigned to receive either 2 L of oxygen by nasal cannula during cesarean delivery only (standard care) or 10 L of oxygen by nonrebreather mask (intervention group) during and for 2 hours after cesarean delivery. Women who underwent scheduled or intrapartum cesarean delivery were eligible and were observed for 1 month after the procedure. The primary composite outcome was maternal infectious morbidity, which included endometritis and wound infection.
Results:
Five hundred eighty-five women were included in the final analysis. Infectious morbidity occurred in 8.8% of patients in the standard care group and in 12.2% of patients in the supplemental oxygen group. There was no significant difference in the rate of infectious morbidity between the standard care and intervention groups (relative risk, 1.4; 95% confidence interval, 0.9-2.3).
Conclusion:
Supplemental oxygen does not reduce the rate of postcesarean delivery infectious morbidity, including endometritis and wound infection.

01:30Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
