Background: Comatose patients are exposed to sensory deprivation in the intensive care units. Auditory stimulation of patients who are unconscious is a nonmedical procedure. This study examines the effect of organized voice, performed by a nurse, on the state of consciousness of comatose patients in intensive care units. Method: This randomized controlled trial study of 60 patients was conducted fitting between August 2017 and February 2018. For 10 days, patients received the voice of a male nurse twice a day in the morning and night shifts, recorded on MP3 and repeated at least 3 to 4 times. Glasgow Coma Scale (GCS) scores were recorded by the researcher before and after auditory stimulation. Results: Patient mean age was 69.2 years; 56.7% of the experimental group and 53.3% of the control group were male. On the first day in the morning and evening after auditory stimulation, the mean GCS was 4.8 in the experimental group and 4.7 in the control group. Before and after the intervention on the 10th day after auditory stimulation, the mean GCS of patients was 9.5 in the experimental group and 7.1 in the control group in the morning and 9.6 and 7.2, respectively, in the evening. No significant differences in mean GCS by group were observed for the first 3 days (P > .05). However, the difference in mean GCS scores of the 2 groups was statistically significant after the third day (P < .05). Conclusions: Auditory stimulation is associated with higher GCS in comatose patients.

The purpose of this work was to review the current literature evaluating the efficacy of clinical protocols and preservation methods in preventing ventilator-associated pneumonia (VAP), and to examine the data obtained from the studies systematically. Materials and Methods: Articles reached by scanning national and international databases including "Google Scholar", "Pubmed", "Science Direct", "Proquest", "Cochrane"," EBSCOhost", "Clinical Key", "Ovid", "Web of Science", "Google Akademik" between 2012-2017 were included in this review. In this review, articles with publication language Turkish or English, which evaluated the effects of (VAP) preventing protocols and applications on the results, whichwere published in last five years and of which full text was available were collected by using keywords; "VAP prevention", "Prevention of VAP", "Prevent VAP", "VAP prevention", "Prevent VAP", and "Prevention of VAP". A total of 48 studies which met the inclusion criteria constituted the sample of the study. Results: Randomized controlled; prospective, randomized controlled; semi-experimental; pilot, randomized controlled, prospective, cluster randomized controlled, open label; monocentric ÖZ Amaç: Bu çalışmanın amacı, ventilatör ilişki pnömoniyi önlemede klinik protokollerin ve koruyucu önlemlerin etkinliğini değerlendiren mevcut literatürün gözden geçirilmesi ve çalışmalardan elde edilen verilerin sistematik biçimde incelenmesidir.
