Explaining ethical challenges and practical solutions from a nursing managements' perspective: A phenomenological study.

Introduction and Objective: Ethical practice is a vital aspect of nursing interventions. Complying with the ethical aspects of the intervention procedure in a stressful nursing environment is not easy and nurse managers always face ethical challenges which are in conflict with their personal values and norms. Identifying and solving these challenges improves the efficiency and effectiveness of nursing care activities. Therefore, this research was done to explain the ethical challenges of nurse managers and practical solutions from their perspective. Material and Method: It is a qualitative study that was carried out based on the phenomenological method in 2022. The participants of this study were 20 nurse managers of Arak hospitals who were selected by purposive sampling until data saturation. The data were collected through semi-structured interviews for 30 to 90 minutes. Data collection was carried out with the participant's consent, using a digital recording device and verbatim transcription, and then it was analyzed using Van Manen's six-step hermeneutic phenomenological approach. Findings: The results of this study could provide a clear picture of ethical challenges and their practical solutions from the nurse managers' perspective in the form of four themes of managerial ethical challenges which include challenges facing physicians, organizations, employees, managers, and three themes for practical solutions, including organizational solutions, interpersonal solutions, and educational solutions which were manifested. Conclusion: Nurse managers are always faced with ethical challenges in their daily activities. To deal with these challenges, they must be familiar with the rules and principles of professional ethics, practical standards, and laws related to patients' rights. Ethical principles and awareness of the ethical decision-making process are useful and effective in having capable and ethical nurses who provide competent care. To deal with ethical challenges, it is suggested to consider self-care strategies and structural and specialized support in each center, which will ultimately lead to the improvement of service quality and the promotion of ethics in care-treatment environments.

Effects of acupressure on sleep quality and anxiety of patients with second- or third-degree burns: a randomized sham-controlled trial.

BACKGROUND: Although acupressure is proposed to boost sleep quality and alleviate anxiety in various disorders, no trials have yet documented these consequences in burn victims. Considering the high importance of managing sleep quality and anxiety among burn patients utilizing adjunctive non-pharmacological measures, this study sought to investigate the impacts of acupressure on sleep quality and anxiety among a population of Iranian patients with burn injuries. METHODS: This trial was performed on 72 patients with second- or third-degree burns, who were divided into two equal arms to receive routine care plus 10-minute acupressure on either real acupoints (i.e., Yintang and Shen men) or sham points for three consecutive nights. Sleep quality and anxiety were investigated at baseline (T1) and on the fourth day (T2) by using St. Mary's Hospital Sleep Questionnaire (SMHSQ) and Spielberger's State-Trait Anxiety Inventory for State Anxiety (STAI-S), respectively. RESULTS: The mean scores of SMHSQ and STAI-S were significantly lower in the real acupressure arm at T2 (P < 0.001 in two cases), implying better sleep quality improvement and higher anxiety alleviation. Also, the reduction in mean changes of SMHSQ and STAI-S scores from T1 to T2 was significantly more in the real acupressure arm (P < 0.001 in two cases). CONCLUSION: Acupressure, as a low-cost complementary method, could be potentially helpful in enhancing sleep quality and decreasing the anxiety of burn patients. Additional long-term trials are required to identify the sustainability of the findings.

Comparing the Effect of Ketamine and Lidocaine on Agitation and Pain in Rhinoplasty: A Randomized Clinical Trial.

Background: Emergence agitation (EA) is an important clinical problem that occurs during the initial period of recovery from anesthesia. This study aimed to determine the effects of ketamine and lidocaine administered on agitation level, postoperative pain, and hemodynamic changes in adults after rhinoplasty. Materials and Methods: Totally 72 patients scheduled to undergo elective rhinoplasty were enrolled in this prospective study. Patients were randomly divided into three groups including control group (n = 24), ketamine group (n = 24), and lidocaine group (n = 24). Twenty minutes before surgery completion, 1 ml saline was administered intravenously to the saline group, while 0.5 mg/kg ketamine or 1.5 mg/kg lidocaine was administered to two other groups. The emergence agitation level of the patients was evaluated using the Richmond Agitation-Sedation Scale just after extubation and in the post-anesthesia care unit (PACU). Postoperative pain was evaluated by Numerical Rating Scale that scored (from 0 to 10) every 10 min until the patients were discharged from PACU. Results: There was a significant difference between EA level between ketamine (P = 0.049) and lidocaine (P = 0.019) groups compared to the control group, and there was a significant difference between pain level between the ketamine (P = 0.008) and lidocaine (P = 0.035) groups compared the to control group, while there was no significant difference between the level of agitation (P = 0.922) and level of pain (P = 0.845) after extubation between the ketamine and lidocaine groups. Conclusion: Ketamine and lidocaine are highly effective in preventing EA and pain control. Further studies with a greater sample size and longer follow-up period are needed to confirm the current findings.

Effect of Nebulized Eucalyptus on Arterial Blood Gases and Physiologic Indexes of Mechanical Ventilated Patients: A Randomized Clinical Trial.

Introduction: Arterial hypoxia is one of the most common findings in critically ill patients. Inhaled medications in ventilated patients can reduce airway resistance, facilitate dilution, and prevent airway infections. This study aimed to examine the effects of nebulized Eucalyptus (NE) on arterial blood gases (ABG) and physiologic indexes of patients receiving mechanical ventilation (MV). Methods: The current randomized clinical trial was performed in three intensive care units (ICUs) of Al-Zahra Hospital in Isfahan, Iran. Using purposive sampling method, 70 intubated patients were selected and randomly divided into NE (n=35) and control (n=35) groups. NE group received 4 ml (5%) Eucalyptus in 6 mL normal saline (NS) every 8 hours since intubation to 3 days by a nebulizer. Control group received 10 mL NS in the same way. Glasgow Coma Scale (GCS) and ABG parameters (pH, BE, HCO3, PCO2, SaO2, and PaO2), and the peak inspiratory pressure (PIP) and tidal volume (TV) were equally assessed in both intervention and control groups. Data were analyzed using SPSS software version 13. Results: There was no significant difference between the patients of both groups in terms of vital signs (blood pressure, temperature, respiratory rate, and pulse rate), GCS, pH, BE, HCO3, PCO2, SaO2, PaO2, PIP, and TV before the study. Amongst the parameters of ABG, there was a significant difference between PaO2 and SaO2 and PIP in the intervention and control groups 3 days after intervention. Conclusion: Inhaled Eucalyptus can improve oxygenation and reduce airway pressure in patients undergoing MV.

Exposure keratopathy and its associated risk factors in patients undergoing general anesthesia in nonocular surgeries.

INTRODUCTION: The most common eye injury during and after general anesthesia is corneal abrasion which can occur at any time after anesthesia and even up to 24 h after it. The aim of this study was to investigate the incidence and factors associated with corneal injury in patients undergoing nonocular surgery. METHODS: This was a descriptive cross-sectional study. A total of 170 patients, who were admitted to the operating room and met the inclusion criteria, were selected through simple nonprobability sampling. Data collection forms were used in order to assess the incidence of corneal injury and its related risk factors. The National Eye Institute scale with fluorescein paper and cobalt blue light by slit lamp were utilized to examine exposure keratopathy. RESULTS: Overall, the results showed that the incidence of keratopathy immediately after eye care removal was found to be 64.7% in the operating room, 65.9% in the recovery room, and 41.2% in 24 h after the surgery. Smokers' patients and drug abusers under general anesthesia underwent endotracheal intubation, received more opioids preoperatively, and had more perioperative bleeding and fluid intake. Moreover, in patients who had received more oxygen flow in the recovery room; the rate of keratopathy was higher. CONCLUSION: Smoking, drug usage, and receiving endotracheal intubation are the risk factors of keratopathy. Therefore, for high-risk patients and procedures, it is indispensable to both obtain preoperative information and take intraoperative precautions in order to prevent eye injuries. Future studies are needed to demonstrate these finding.

The Effects of Passive Blinking on Exposure Keratopathy among Patients in Intensive Care Units.

Background: Patients in Intensive Care Units (ICUs) are at risk of eye disorders such as Exposure keratopathy (EK) due to impaired blinking and incomplete eye closure. The aim of this study was to assess the effects of passive blinking exercise (PBE) on EK among patients in ICUs. Materials and Methods: This single-blind, randomized, clinical trial was conducted in 2017. The study participants included 51 patients purposively recruited from the three ICUs of Valiasr Teaching Hospital, Arak, Iran. Through coin tossing, one eye of each participant was randomly allocated to the intervention group and the other to the control group. The eye in the control group received routine eye care, whereas the eye in the intervention group received routine eye care and PBE for a week. EK prevalence and severity were assessed daily for 7 consecutive days using fluorescein eye staining papers and an ophthalmoscope with a cobalt blue filter. Results: The study groups did not significantly differ from each other in terms of the baseline prevalence and severity of EK. After the intervention, the prevalence of EK (χ 2 = 13.44, df = 1, p < 0.001) and the prevalence of grade II EK (χ 2 = 8.33, df = 1, p = 0.003) in the intervention group were significantly lower than the control group. Conclusions: PBE is effective in significantly reducing EK prevalence and severity among patients in ICUs. Therefore, critical care nurses are recommended to use PBE for EK prevention and management.

The Effect of Sumatriptan, Theophylline, Pregabalin and Caffeine on Prevention of Headache Caused By Spinal Anaesthesia (PDPH): A Systematic Review.

Spinal anaesthesia (SA) is a common method during surgery due to easy administration, rapid effects, relaxes muscles and controls pain. But, post-dural puncture headache (PDPH) is a common problem after SA that occurs in 6%-36% of SA. We assessed the effect of four common treatment drugs sumatriptan, theophylline, pregabalin and oral caffeine on prevention of PDPH. In this systematic review, all randomized clinical trials (RCTs) during January 2015 and December 2021 were searched from PubMed, Google Scholar, Web of Science, Cochrane review and Clinical Key with a specific search strategy. The article qualities were assessed by two independent authors and were screened for relevant sources based on inclusion and exclusion criteria. Moreover, the included articles data were extracted and checked for regular basis. A total of 421 articles were identified and 193 articles were removed following a preliminary review and finally, 14 articles were included in review. Overall, we identified five RCTs on the effect of caffeine, two RCTs on the effect of sumatriptan, three RCTs on theophylline, three RCTs on pregabalin and one RCT on theophylline and sumatriptan in PDPH prevention. This review supports the effects of theophylline, pregabalin and sumatriptan in the prevention of PDPH incidence and treatment of PDPH intensity, but we cannot draw the same conclusions about caffeine due to some negative results about the caffeine effect. Nevertheless, this extracted conclusion should be considered and interpreted with caution and limited generalizations due to the small number of studies, the variety of evaluated drugs and measures, the low sample size and the bias presented.

The effect of Shiatsu massage on agitation in mechanically ventilated patients: A randomized controlled trial.

BACKGROUND: Patients admitted to the intensive care units encounter many complications due to the nature of the disease and invasive medical procedures such as intubation and mechanical ventilation. Among these complications, agitation is a frequently-observed and serious problem. OBJECTIVES: This study aimed to investigate the effect of Shiatsu massage on agitation in mechanically ventilated patients. METHODS: In this randomized controlled trial, a total of 68 mechanically ventilated patients were selected and then randomly assigned to two groups of intervention and control. Patients in the intervention group received three 5-minute periods of Shiatsu massage with a 2-minute break between them, while patients in the control group only received a touch on the area considered for the message. Data were collected before and after the intervention using the Richmond Agitation-Sedation Scale (RASS) and then analyzed using IBM SPSS Statistics for Windows, version 25.0 (IBM Corp., Armonk, N.Y., USA). RESULTS: The results showed that the level of agitation significantly decreased in the intervention group compared to the control group (p=.001). CONCLUSION: Application of shiatsu massage seems to be effective in managing agitation in mechanically ventilated patients. Further studies with greater sample size and longer follow-up period are needed to confirm the current findings.

Effect of nebulized eucalyptus on contamination of microbial plaque of endotracheal tube in ventilated patients.

BACKGROUND: Formation of biofilm and bacterial colonization within the endotracheal tube (ETT) are significant sources of airway contamination and play a role in the development of ventilator-associated pneumonia (VAP). This study was conducted to examine the effect of nebulized eucalyptus (NE) on bacterial colonization of ETT biofilm. MATERIALS AND METHODS: We performed a randomized clinical trial in three intensive care units (ICUs) of an educational hospital. Seventy intubated patients were selected and randomly divided into intervention (n = 35) and control (n = 35) groups. The intervention group received 4 ml (5%) of eucalyptus in 6 ml normal saline every 8 h. The placebo group received only 10 ml of normal saline in the same way. On extubation, the interior of the tube was immediately sampled using a sterile swab for standard microbiological analysis. Chi-square and Fisher's exact tests were used for statistical analysis in SPSS. P values less than 0.05 were considered statistically significant. RESULTS: In both samples, Klebsiella pneumoniae and Acinetobacter baumannii were the most frequently isolated bacteria. In the control group, heavy colonization was greater than in the intervention group (P = 0.002). The frequency of isolation of K. pneumoniae in the intervention group was lower than in the control group (P < 0.001). However, there was no difference between the two groups in other isolated bacteria. CONCLUSIONS: NE can reduce microbial contamination of the endotracheal tube biofilm in ventilated patients. Moreover, K. pneumoniae was the most sensitive to NE.

Gas-diffusion flow injection determination of Hg(II) with chemiluminescence detection.

A gas-diffusion flow injection method for the chemiluminescence detection of Hg(II) based on the luminol-H(2)O(2) reaction was developed. The analytical procedure involved the injection of Hg(II) samples and standards into a 1.50 M H(2)SO(4) carrier stream, which was subsequently merged with a reagent stream of 0.60% (w/v) SnCl(2) in 1.50 M H(2)SO(4) to reduce Hg(II) to metallic Hg. The gas-diffusion cell was thermostated at 85 degrees C to enhance the vaporisation of metallic Hg. Mercury vapour, transported across the Teflon membrane of the gas-diffusion cell into the acceptor stream containing 1.00 x 10(-4) M KMnO(4) in 0.30 M H(2)SO(4), was oxidised back to Hg(II). The acceptor stream was merged with a reagent stream containing 2.50 M H(2)O(2) in deionised water and then the combined stream was merged with another reagent stream containing 7.50 x 10(-3) M luminol in 3.00 M NaOH at a confluence point opposite to the photomultiplier tube of the detection system. The chemiluminescence intensity of the luminol-H(2)O(2) reaction was enhanced by the presence of Hg(II) in the acceptor stream. The corresponding increase was related to the original concentration of Hg(II) in the samples and standards. Under optimal conditions, the chemiluminescence gas-diffusion flow injection method was characterised by a linear calibration range between 1 microg L(-1) and 100 microg L(-1), a detection limit of 0.8 microg L(-1) and a sampling rate of 12 samples per hour. It was successfully applied to the determination of mercury in seawater and river samples.

On-line determination of mercury(II) by membrane separation flow injection analysis.

A rapid and inexpensive gas-diffusion (GD) flow injection method for the on-line determination of Hg(II) in aqueous samples is described. The analytical procedure involves the injection of a Hg(II) sample into a 1.5M H(2)SO(4) carrier stream which is merged with a reagent stream containing 0.6% SnCl(2) and 1.5M H(2)SO(4). Under these conditions Hg(II) is reduced to metallic mercury which partially evaporates through a Teflon membrane into an acceptor stream containing 1.75x10(-4)M KMnO(4) in 0.3M H(2)SO(4). The decrease in the absorbance of the acceptor stream at 528nm corresponding to the absorption maximum of the permanganate anion can be related to the original concentration of Hg(II) in the sample. The method is characterized by a detection limit of 4mugl(-1) and a sampling frequency of 8h(-1). The flow system was successfully applied to the analysis of river samples spiked with Hg(II).
