Guidance for the Prevention and Control of Influenza in the Peri- and Postpartum Settings

Posted by: admin  :  Category: Information

Pregnant women have been shown to be at increased risk of severe illness, hospitalizations, and death from complications of influenza. General Prevention Strategies for Seasonal Influenza in Health Care Settings are currently available and apply to all health care settings. Those general strategies outline infection control precautions for all patient care including care of women and newborns within the labor, delivery, recovery, and postpartum settings. The following highlights some of the vital recommendations contained in this guidance as well as supplemental strategies specific to hospitalized pregnant, intrapartum, and postpartum women and their newborns during the birth hospitalization.Additional information about the use of antiviral drugs in pregnant and postpartum women is also available on the CDC web site. While data are limited, these recommendations are based upon evidence available to date, and will be revised accordingly if new data are available in the future.

Pre-DeliveryPrior to delivery, a hospitalized pregnant woman with suspected or laboratory-confirmed influenza should be placed in a private room on Droplet Precautions and instructed to follow respiratory hygiene and cough etiquette, including wearing a facemask, if being transported outside of her room.Health care personnel entering rooms of pregnant women with suspected or confirmed influenza should adhere to Standard and Droplet Precautions, including donning a facemask upon entry into the room, performing hand hygiene, wearing gloves for any contact with potentially infectious materials, and wearing gowns for any patient-care activity where contact with body fluids may occur.Droplet Precautions should be continued for hospitalized patients with suspected or confirmed influenza for 7 days after illness onset or until 24 hours after the resolution of fever and respiratory symptoms, whichever is longer, while the patient is in a health care facility. Patients placed on Droplet Precautions should be discharged from medical care when clinically appropriate, not based on the period of potential virus shedding or recommended duration of Droplet Precautions.The peripartum patient and her family members and other visitors should be informed of the risks of influenza virus transmission and instructed to adhere to respiratory hygiene and cough etiquette, hand hygiene, and use of personal protective equipment (PPE) according to current facility policy.During DeliveryPatients with suspected or confirmed influenza who are in the labor and delivery suite should remain on Droplet Precautions.Health care personnel in the delivery suite should adhere to Standard and Droplet Precautions, including practicing hand hygiene before and after handling the newborn.After DeliveryAlthough it is well-recognized that the ideal setting for care of a healthy-term newborn while in the hospital is within the mother’s room, newborns that become infected with influenza are at increased risk for severe complications. To reduce the risk of influenza in the newborn, CDC recommends that facilities consider temporarily separating the mother who is ill with suspected or confirmed influenza from her baby following delivery during the hospital stay. Throughout the course of temporary separation, all feedings should be provided by a healthy caregiver if possible. Mothers who intend to breastfeed should be encouraged to express their milk.The optimal length of temporary separation has not been established, and will need to be assessed on a case-by-case basis after considering many factors.Guidelines during the 2009 H1N1 pandemic recommended that: Separation should continue until all of the following were met: the mother had received antiviral treatment for >48 hoursthe mother was afebrile without antipyretics for >24 hours, andthe mother was able to control her cough and respiratory secretions.If co-location (sometimes referred to as
