Abstract
Background
Record based review of the 2009 H1N1 Influenza pandemic suggests that pregnant women are at higher risk for hospitalization and death due to H1N1 Influenza.
Aims
To study the clinical profile and outcome of critically ill pregnant females admitted in intensive care unit (ICU) with real-time recombinant polymerase chain reaction (rRT-PCR) proven positive H1N1 cases.
Methods
A retrospective record-review based study was conducted at Sir SayajiRao General Hospital (SSGH) and Medical College, Vadodara on data of confirmed rRT-PCR H1N1 pregnant females admitted during the pandemics of 2010and 2015. Demographics, clinical profile and laboratory investigations were recorded and outcomes (survived or expired) were analysed.
Results
There were a total of 20 H1N1 positive pregnant females requiring ICU admission. With equal demographic distribution among rural and urban population, cough and fever were the most common presenting complaints. 65 per cent were in third trimester, the subgroup which also had the highest mortality. Mean days from onset until presentation was 5.05 days. 12 (60 per cent) patients’ required invasive mode of ventilation and all died. Average hospital stay was 7 days. Foetus had favourable outcome in patients who recovered from H1N1 acute illness.
Conclusion
Pregnant females in our study had 60 per cent mortality. Thus, awareness, early diagnosis and treatment should be provided to them. Guidelines, policy changes and government protocols are required specifically for pregnant females with H1N1 Influenza A infection. Our study was an observational study and comparisons with non-pregnant females were not done, conclusions applicable to entire pregnant population was not derived.
