Background & Aim: High frequency of traumatic and non-traumatic brain injuries in one hand and improvement of the health care condition to restore patient&aposs life in the other hand has increased the frequency of comatose patients in ICU. These patients often experience physical, cognitive, behavior or sensory defects, and the sensory input reduction in intensive care units expose them to cognition disorders. It seems that using sensory stimulation programs may be effective in preventing from sensory deprivation and facilitating recovery process.

Methods & Materials: In this quasi-experimental study, 30 comatose patients who were hospitalized in ICU in Shariati and Sina hospitals were sought to be studied. The subjects were selected randomly using matching that was placed in case and control group. In the intervention group, patients received an auditory stimulation for 2 weeks, 6 days of a week, 2 times a day. The auditory stimulator was a recorded tape (5-10 minutes) of a familiar voice for 30 minutes. The Glasgow Coma Scale (GCS) was used for measuring the level of consciousness (LOC). LOC was measured before and after each intervention 4 times a day. The control group LOC was measured in a similar manner to the case group. At the same time, homodynamic symptoms (blood pressure, pulse rate, and mean arterial pressure) were measured. Non-parametric test was used for analyzing data. The data was analyzed through SPSS V.11.5 computer software.

Results: The findings indicated that there was a significant difference in LOC of the intervention group at the first day and after fourteen days of the intervention (P<0.001), but not in the control group (P=0.769). Although 2 groups were similar in LOC of the first day (P=0.605) but there were a significant difference between their LOC at the fourteenth day (P=0.001).

Conclusion: The results showed that the auditory stimulations with familiar voice were effective in increasing LOC in the comatose patients. It is suggested that nurses expose comatose patients with auditory stimulations using a recorded tape of familiar voice in ICU.

Background & Aim: The presence of pain is a common phenomenon among patients in critical care units. Critically ill patients are often unable to communicate because of illness or sedation so, recognition and assessment of their pain is difficult. In these patients, observational behavioral indices can be used to evaluate pain. The aim of this study was to investigate the effect of application of critical-care pain observation tool in patients with decreased level of consciousness on performance of nurses in documentation and reassessment of pain after palliative intervention.

Methods & Materials: In this before and after quasi-experimental study, 106 nurses working in general intensive care units in selected hospitals affiliated to Tehran University of Medical Sciences were selected. First, we examined the nurses&apos performance three times in relation to documentation and reassessment of pain after palliative intervention, position change and suction procedure in patients with decreased level of consciousness using a researcher-made check list. Then, we taught nurses individually, how to use this tool to investigate the pain of patient in a session lasting an hour. A week after the training, the researcher reevaluated performance of trained nurses in relation to documentation and reassessment of pain after palliative intervention in patients with decreased level of consciousness. Finally, those data collected before and after the training of the CPOT to nurses were compared using the Wilcoxon test.

Results: Findings showed that the CPOT could not lead to improved nurses&apos function in relation to documentation of pain in the patients records (P=0.209) and recording palliative measures related to pain (P=0.117). However, there were significant statistical differences between nurses&apos function in relation to reassessment of pain after palliative intervention, before and after the training and application of the CPOT. Comparing the mean function scores before and after the intervention, demonstrated that the performance of nurses in this area has been improved after the intervention.

Conclusion: The critical-care pain observation tool can increase nurses&apos sensitivity to pain in patients with decreased level of consciousness. It forces the nurses to reassess the pain after palliative intervention. This tool does not motivate in nurses to document pain palliative process. So it is recommended that future studies investigate the impact of this tool on other aspects of pain management, such as diagnosis of pain and using of drugs and non-drug measures.

Background & Aim: Decreased level of consciousness is one of the life-threatening complications associated with brain injuries. The aim of the study was to explore the effect of auditory and tactile stimulation by a family member on patients’ consciousness level.
Methods & Materials: This quasi-experimental study was conducted on 80 comatose patients with traumatic brain injury hospitalized in the intensive care units of Zahedan educational hospitals in 2019. Samples were selected by the convenience sampling methods and then randomly divided into experimental or control groups. Data collection tool included a demographic information questionnaire, and FOUR criteria for the level of awareness. For the experimental group, the intervention including auditory and tactile stimulation was performed by a family member for 10 minutes for seven consecutive days. The control group received routine interventions. To analyze the data, descriptive and inferential statistical tests (independent t-test, paired t-test, analysis of covariance, chi-square and repeated measures ANOVA) were used through the SPSS software version 21.
Results: The results indicated no significant differences in the level of consciousness between the two groups on the first and fourth days. Yet, independent t-test, analysis of covariance and repeated measures ANOVA showed that the intervention group had significantly a higher level of consciousness on the fifth, sixth and seventh days compared to the control group (P<0.001).
Conclusion: Findings showed that auditory and tactile stimulation by a family member is effective in increasing the level of consciousness in comatose patients with brain injury. So, this technique is recommended as an intervention in nursing care to increase the consciousness level in these patients.
