A well-known disease, Acute Respiratory Distress Syndrome (ARDS) presents a daunting challenge to the medical community with alarmingly high mortality rates. Initiation of hypertonic saline (HTS) nebulization therapy for patients with early ARDS appears to be tolerable and may be beneficial. However, using a nebulizer is cumbersome and less efficient. This study aims to assess the efficacy of using HTS3% in a nebulizer in comparison with intravenously injecting it to attenuate the manifestation of ARDS. The study analyses factors such as the severity of the disease, need and duration of mechanical ventilation (MV), ICU stay, and mortality rate in the comparative analysis.

Materials and Methods:

The randomized, comparative, and controlled study included patients of both genders from an age bracket of 18-60 years. The patients fulfilled the Berlin definition of ARDS. Additionally, the whole sample was divided into four groups (26 patients each): Group A received standard pharmacotherapy [methylprednisolone 1mg/kg/day intravenously and salbutamol nebulizer 2.5 mg (1 ml) + 3 ml normal saline/8hr] and normal saline 0.9% (5ml) nebulizer /8hr: Group B received standard pharmacotherapy + HTS2.7% (5ml) nebulizer/8hr: Group C also received standard pharmacotherapy and 500ml normal saline intravenously over 24 hours: Group D received standard pharmacotherapy and 500 ml HTS 3% intravenously over 24 hours. The following parameters were recorded: Lung injury score (Murray Score, calculated every 24 hours), the incidence of the need for MV, duration of MV, length of ICU stay, and mortality rate.


Group B (HTS nebulizer group) and group D (HTS IV group) showed the most rapid improvement in the Murray score with a 50% decrease in the score from its initial value (D50%) by day 4 with P-values of 0.013 and 0.022 respectively. Subjects from Group D (HTS IV) and Group B (HTS Nebulizer) were the least in need of MV as only 38.5% needed MV with a P-value <0.001. In comparison, 69.2% subjects from group A (control) and 73.1% from group C required MV, with a P-value <0.001. The shortest duration of MV care was found in group D (median 3.12 days), followed by group B (median 4.21 days). The results were highly significant, with P-value 0.004 when compared with group A (control group) and group C. In addition, the longest duration of MV care was reported in group A (median 5.37 days). There was significant variation in all groups regarding the length of ICU stay: group D required the least number of days (median 6.76 days), followed by group B (median 7.08 days). The result was statistically significant, with a P-value of 0.004 when compared with the control group (median 9.1 days) and group C(longest duration of MV with a median of 10.13 days). However, no significant difference was found in the mortality rate (P-value >0.05).


The use of hypertonic saline 3% intravenously has a comparable effect as the use of hypertonic saline 3% via nebulizer to attenuate the manifestations of (ARDS) and even superior in the mechanically ventilated patient.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."

Daniel Pesut
(Indiana University School of Nursing, USA)

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

J. Ferwerda
(University of Oxford, UK)

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
