Gap in the Literature

Gap in Literature
LR employment can help decrease duration of dependency on mechanical ventilators and the resultant PICU outcomes. Methodical LR review protocol among pediatric patients receiving mechanical ventilation has, of late, been recorded with the international prospective register of systematic reviews (PROSPERO). Limited quantities of superior-quality scientific proofs exist that inform the effectiveness and safety of ETS within pediatric settings. This is mainly because of the absence of clinical trials informing bedside practice (Bilan & Molayi, 2016).
Literature on the subject indicates that suction using normal saline, or in the absence of it, alters respiratory and hemodynamic parameters. While the former has adverse effects, changes aren’t significant with the exception of elevated heart rate, which indicates minor risk. But the outcomes of other research works reveal a significant linkage. The outcomes of the current research may, perhaps, be attributed to a different research design and the absence of samples; hence, there is a need for a broader research. Additionally, literature does not shed much light on how airway pressure is impacted by suction. In this respect, a research on suction’s physiologic impacts (without as well as with normal saline) upon peak airway pressure, atrial blood gas value, and respiratory rate did not signify any inter-technique significant difference. Nevertheless, systematic reviews highlight that not much information exists on usefulness, risks and adverse effects of normal saline. Improvement in clinical trial quality is needed, to this end. Performing researches using a larger sample size and different designs, in addition to measurements at different intervals, is recommended (Adib, Ghanbari, Alavi & Leyli, 2014).
Because of the controversial records and proofs associated with choosing a sounder deep and shallow suctioning technique, additional researches can attempt at comparing the impacts of these techniques on ICU patients’ cardiovascular indices. The outcomes would aid in introducing best practices to nursing pupils and practitioners, so that the procedure can be carried out without any major complications arising (Irajpour, Abbasinia, Hoseini & Kashefi, 2014).
