However, these American guidelines have not yet recommended the prophylactic use of systemic antibiotics for all intubated patients, which awaits the availability of further data. However, recent ATS/IDSA 2016 guidelines<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">8</span></a> only discuss recommendations on VAP diagnosis and antibiotic treatment. These current guidelines mention no prevention measures for nosocomial pneumonia.</p><p id="par0040" class="elsevierStylePara elsevierViewall">In 2007, the Brain Trauma Foundation published the 3rd edition of its Guidelines for the management of severe traumatic brain injury,<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">9</span></a> describing the results of this initial RCT, and suggests the immediate application of this pharmacological measure to reduce VAP incidence in intubated traumatic brain injury patients.</p><p id="par0045" class="elsevierStylePara elsevierViewall">From a European perspective, guidelines published in 2009<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">10</span></a> present the short course of IV antibiotics as a strategy that requires further study to be systematically recommended in intubated patients for VAP prevention.</p><p id="par0050" class="elsevierStylePara elsevierViewall">A very interesting initiative to reduce VAP has recently been developed by the Spanish Societies of Intensive Care Medicine and Intensive Care Nursing, being defined as “Zero-VAP”,<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">2</span></a> which proposed the implementation of a simultaneous multimodal intervention in ICU consisting of a bundle of VAP prevention measures. The “Zero-VAP” Project incorporates an integral patient safety programme and continuous online validation of bundle application. The implementation of the guidelines aims at reducing VAP to less than 9 episodes per 1000 days of mechanical ventilation. A total of 35 preventive measures were initially selected. A group of experts have generated a list of 7 basic mandatory recommendations: education and training in airway management, strict hand hygiene for airway management, cuff pressure control, oral hygiene with chlorhexidine, semi-recumbent positioning, promotion of measures to safely avoid or reduce time on ventilator, and discouragement of scheduled changes of ventilator circuits, humidifiers and endotracheal tubes; as well as 3 additional highly-recommended measures: selective digestive-tract decontamination, aspiration of subglottic secretions, and a short course of IV antibiotic.</p><p id="par0055" class="elsevierStylePara elsevierViewall">After a review of literature and the international guidelines that have been published since the publication of the initial work, the question that we make is: where are we now? The answer is simple. Since the single RCT study performed twenty years ago, the current clinical practice has changed and there is no uniform management of intubated patients with coma. The fact that the type and dose of IV antibiotic was different in all the aforementioned studies suggests that the positive effect of IV antibiotic prophylaxis depends more on immediate administration upon intubation – to counteract bacterial inoculum in the upper airways – than on antibiotic type and dose. This preventive measure may now be obsolete due to changes in the colonizing microorganisms of the population or due to a multifactorial behaviour in VAP development in coma patients. It is surprising that, throughout all these years, no research has been focused on this hypothesis and tested this or any other antibiotic using a large randomized clinical trial.</p></span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0020">New strategies for future research in antibiotic prophylaxis against VAP</span><p id="par0060" class="elsevierStylePara elsevierViewall">Patients with structural coma, usually due to traumatic head injury, are nearly always intubated in emergency conditions outside the hospital, where the lack of aseptic conditions makes it easier for microorganisms to enter the respiratory tract. In the initial study, trachea colonization within 24<span class="elsevierStyleHsp" style=""></span>h of intubation by “community microorganisms” was observed to be a risk factor for EO-VAP development in patients with head trauma. Due to this fact, in the last years an increase in the etiologic cause of EO-VAP has been observed due to enteric bacteria from gastrointestinal microbiota, commonly resistant to cefuroxime or/and amoxicillin-clavulanic acid. Furthermore, high oxygen tension in ventilated patients is enough to kill anaerobes and – in this situation of new microbiology patterns of VAP – we and others propose the use of other antibiotics rather than cefuroxime for prophylaxis and for treatment of aspiration pneumonia,<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">11</span></a> which is the pathogenic basis of EO-VAP in intubated patients with altered level of consciousness.</p><p id="par0065" class="elsevierStylePara elsevierViewall">Consequently, we believe that it is time to risk a change to an antibiotic prophylaxis which is likely to be more effective against aerobic gram-positive and enteric gram-negative bacilli, as well as a change in terms of pharmacokinetics and pharmacodynamics with a more adequate spectrum to the current aetiology of EO-VAP in recently-intubated coma patients. However, the effect of this prophylactic measure on the development of bacterial resistance must always be monitored periodically to detect prophilaxis-related bacterial resistance if its use is not appropriate.
