Mask-related pressure injury prevention associated with non-invasive ventilation: A systematic review.

Noninvasive ventilation interfaces are one of the main factors contributing to pressure injuries caused by medical devices. Prevention is still the best course of action when discussing noninvasive ventilation-induced pressure injuries. A systematic review was designed to summarize and analyse all published literature on strategies to prevent pressure injuries caused by masks in patients undergoing noninvasive ventilation. The protocol of the systematic review followed the PRISMA guideline. An extensive search from the beginning to May 16, 2023, using current articles in databases such as Web of Science (WOS), Scopus, PubMed, and Cochrane Library was conducted. Medical Subject Headings (MESH) were used as follows: "Pressure Injury," "Noninvasive Ventilation," "Prevention," and "Pressure Sore." Any language-published studies that met the inclusion criteria were included in this review. A risk of bias assessment was conducted using the Joanna Briggs Institute tool, including evaluation methodologies for all studies. Database searches yielded 2546 articles, which were reduced to 23 that met our criteria after reviewing full texts. A narrative synthesis was conducted. As a result, type of interface (14 studies), dressings (4 studies), adjustment of mask leakage (1 study), humidity (1 study), positioning (1 study), and design of personalized masks (2 studies) seem to be a practical approach to prevent pressure injuries caused by masks in patients undergoing noninvasive ventilation. The results of our study show the effectiveness of preventive methods in reducing the incidence of pressure injuries caused by masks. Given the significant occurrence of pressure injury related to noninvasive ventilation and the crucial role of prevention and treatment, it is imperative to conduct more rigorous studies to ascertain the efficacy of each strategy.

The Relationship Between Spirituality and Religiosity with Death Anxiety Among Cancer Patients: A Systematic Review.

This systematic review aimed to summarize the evidence regarding the relationship between spirituality and religiosity with death anxiety (DA) among cancer patients. This systematic review was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) checklist. An extensive search was conducted on electronic databases such as Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database (SID) via keywords extracted from Medical Subject Headings from the earliest to February 9, 2022. The quality of the included studies was assessed using the appraisal tool for cross-sectional studies (AXIS tool). Fifteen studies were selected for inclusion in this systematic review. Nine and six studies assessed the relationship between spirituality and religiosity with DA in cancer patients, respectively. Most studies had a negative relationship between spirituality (n = 8) and religiosity (n = 4) with DA. In sum, most studies showed that religion and spirituality are negatively related to DA in patients with cancer.

The effect of Benson relaxation technique on cancer patients: a systematic review.

PURPOSE: Although many studies have investigated the effect of this method on cancer patients, no review of the available literature has been done. So, a literature review is conducted to evaluate all published literature on the Benson relaxation technique in cancer patients. METHODS: A systematic literature search was conducted. A systematic search of online electronic databases including PubMed/MEDLINE, Scopus Web of Science, PsycINFO, and EMBASE was performed using keywords extracted from Medical Subject Headings such as "Benson Relaxation Technique," "Cancer Patients," "Malignancy," and "Neoplasia" from the beginning to April 27, 2023. A total of 810 publications were assessed for relevance by title and abstract. The remaining 31 articles were examined using inclusion criteria for all Persian and English-language publications that evaluate the effectiveness of the Benson relaxation technique on cancer patients. We did not have gray literature in our review. The methodological quality of the included studies was appraised using specific checklists. RESULTS: Finally, nine studies were included in this systematic review. Studies on breast cancer patients showed improvement in fatigue, nausea, vomiting, pain, shortness of breath, insomnia, anorexia, constipation, diarrhea, treatment side effects, breast symptoms, arm symptoms, worry about hair loss, and scores of hope. Two studies were conducted among cervical cancer patients that showed a decrease in anxiety scores and an improvement in the quality of sleep. Another study on gastric cancer patients showed decreased Chemotherapy-Induced Nausea, Vomiting, and Retching scores. CONCLUSION: Overall, this systematic review showed that the Benson relaxation method could improve sleep quality, appetite, anxiety, and quality of life. Therefore, using the Benson relaxation technique is suggested to improve health-related outcomes in cancer patients.

A systematic review of nurses' practice and related factors toward pressure ulcer prevention.

In most health care centres, pressure ulcers (PUs) are a common concern. This systematic review aimed to summarise nurses' practice and related factors toward PU prevention. An extensive search was conducted on electronic databases such as Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database via keywords extracted from Medical Subject Headings such as "Pressure ulcer", "Pressure sore", "Bedsore", "Practice", and "Nurses" from the earliest to 9 March 2022. The quality of the included studies was assessed using the appraisal tool for cross-sectional studies (AXIS tool). Data extraction and quality assessment of included studies were performed by two researchers independently. A total of 6501 nurses were enrolled in twenty-nine studies. Of the participants, 75.15% were female and 55.64% were single, and 94.57% had a bachelor of science in nursing degree. Mean age and work experience of nurses was 30.69 (SD = 4.73) and 8.61 (SD = 5.44) years, respectively. The mean score of nurses' practices toward the prevention of PUs was 57.58 (SD = 14.62) out of 100. Also, 48.95% of nurses had a desirable practice toward the prevention of PUs. Factors such as knowledge (n = 6), attitude (n = 4), level of education (n = 4), a history of participating in workshops related to the prevention of PUs (n = 3), work experience (n = 2), area of practice (n = 2), self-adequacy (n = 1), follow the literature (n = 1), age (n = 1), and involvement in research (n = 1) had a significant positive relationship with nurses' practice toward PUs prevention. However, the nurses practice of PUs prevention had a significant negative relationship with lack of job satisfaction (n = 1), disproportionate nurse-to-patient ratio (n = 1), and lack of policies and guidelines (n = 1). The level of nurses' practice toward the prevention of PUs was relatively desirable. The result of this study can help improve the practice of nurses toward PUs prevention. Increasing nurses' knowledge and attitude toward PUs prevention can improve their practice. Therefore, it is suggested that policymakers and nursing managers implement PUs prevention education for nurses based on the factors associated with nurses' practice.

Effects of aromatherapy with Rosa damascene and lavender on pain and anxiety of burn patients: A systematic review and meta-analysis.

Pain and anxiety were considered the most common complications of treatment procedures in burn patients. Non-pharmacological drugs, including aromatherapy, can decrease these issues. This systematic review and meta-analysis aim to summarise the effects of aromatherapy with Rosa damascene (RD) and lavender on the pain and anxiety of burn patients. A systematic search was performed on international electronic databases such as Scopus, PubMed, and Web of Science, as well as on Iranian electronic databases such as Iranmedex and Scientific Information Database (SID) with keywords extracted from Medical Subject Headings such as "Burns", "Pain", "Pain management", "Anxiety", and "Aromatherapy" were performed from the earliest to November 1, 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist assessed the quality of randomised control trials (RCTs) and quasi-experimental studies. STATA v.14 software was used to estimate pooled effect size. Heterogeneity was assessed with I2 value. Random effect model and inverse-variance method using sample size, mean, and standard deviation changes were applied to determine standard mean differences (SMD). The confidence interval of 95% was considered to determine the confidence level. A total of 586 burn patients participated in six studies, including three RCT studies and three quasi-experimental studies. The results based on RCT studies showed RD significantly decreased the dressing pain average when compared to the control group (SMD: -1.61, 95%CI: -2.32 to -0.99, Z = 5.09, I2 : 66.2%, P < 0.001). Aromatherapy with lavender decreased the average pain in the interventional group more than in the control group (SMD: -1.78, 95%CI: -3.62 to 0.07, Z = 1.89, I2 : 97.2%, P = 0.06). Using aromatherapy with RD and lavender significantly decreased pain average in the interventional group than the control group (SMD: -1.68, 95%CI: -2.64 to -0.72, Z = 3.42, I2 : 94.2%, P = 0.001). The results showed RD significantly decreased the anxiety average in the interventional group than the control group (SMD: -2.49, 95%CI: -2.98 to -2.0, Z = 9.94, I2 : 51.6%, P < 0.001). Overall, this study showed that aromatherapy with RD decreased pain and anxiety of dressing procedures in burn patients. Although aromatherapy with lavender decreased pain in the patients, it was not statistically significant. More RCTs studies are required to be able to better judge the effects of aromatherapy with RD and lavender on the pain and anxiety of burn patients.

Effects of massage therapy on pain and anxiety intensity in patients with burns: A systematic review and meta-analysis.

This systematic review and meta-analysis aimed to examine the effects of massage therapy on pain and anxiety intensity in patients with burns. A comprehensive, systematic search was conducted in various international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Massage therapy', 'Musculoskeletal manipulations', 'Acute pains', 'Burning pain', and 'Burn' from the earliest to October 17, 2022. Cochran's tool is used to check the risk of bias for randomised clinical trial (RCT) articles. The methodological index for non-randomised studies was used to assess the risk of bias in quasi-experimental studies. STATA version 14 software was used to perform the meta-analysis. A 95% confidence interval (CI) was used to determine statistical significance. Heterogeneity was investigated with I2 . A P-value less than .1 was considered statistically significant for publication bias value. A total of 733 patients with burns were included in seven studies. Five studies had an RCT design and two studies had a quasi-experimental design. The duration of the study was reported in five studies, with a mean of 42.40 weeks. The duration of the intervention was reported in seven studies with a mean of 22.86 minutes. The results of the meta-analysis showed using various types of massage therapy interventions significantly reduced pain intensity in the intervention group compared with the control group (weighted mean difference: -2.08, 95% CI: -2.55 to -1.62, Z = 8.77, I2 : 67.1%, P < .001). Massage therapy intervention significantly reduced the intensity of anxiety in burn patients (standard mean difference: -7.07, 95% CI: -10.13 to -4.01, Z = 4.53, I2 : 98.2, P < .001). Overall, the present systematic review and meta-analysis showed that massage therapy can reduce the intensity of pain and anxiety in burn patients. Therefore, it is recommended that health managers and policymakers pay special attention to massage therapy as a simple, low-cost, and efficient non-pharmacological treatment to relieve pain and anxiety in burn patients.

The Attitude of Iranian Critical Care Nurses Toward Euthanasia: A Multicenter Cross-sectional Study.

Today, one of the major ethical challenges facing the world's health care system, and in particular nurses in the intensive care unit, is euthanasia or death out of pity. The aim of this study was to investigate the attitude of Iranian nurses in the intensive care unit toward euthanasia. This was an analytical cross-sectional study using census sampling. The data collection tool was the Euthanasia Attitude Scale. A total of 206 nurses working in the intensive care unit in 4 hospitals in the Mazandaran province of Iran were included in this study. The mean of total Euthanasia Attitude Scale score in intensive care unit nurses was 2.96. The mean euthanasia dimensions were ethical consideration, practical considerations, treasuring life, and naturalistic beliefs, 3.03, 2.92, 2.98, and 2.99, respectively. There was significant but low negative correlation between age and total Euthanasia Attitude Scale score, ethical considerations, and practical considerations. Male nurses exhibited significantly higher Euthanasia Attitude Scale scores, specifically in regard to ethical and practical considerations compared with female nurses. The most Iranian nurses in the intensive care unit had a negative attitude toward euthanasia for patients in the later stages of the disease. However, this opposition was less than similar studies in Iran in the past.

Knowledge, attitude, and practice of Iranian critical care nurses related to prevention of pressure ulcers: A multicenter cross-sectional study.

INTRODUCTION: Pressure ulcers (PU) are a major, but preventable health problem in all health settings, but especially in intensive care units (ICUs). This study aimed to investigate the knowledge, attitude, and practice (KAP) of Iranian ICU nurses related to the prevention of PU. METHODS: In a cross-sectional study, data obtained from 183 ICU nurses working in four hospitals affiliated to Mazandaran University of Medical Sciences, Sari, Iran were evaluated. The study was conducted from July to October 2020. Data were collected using a four-part questionnaire including demographic characteristics, Pieker Pressure Ulcer Knowledge Test (PPUKT), Attitude toward Pressure Ulcer Prevention (APUP) tool, and the practice of nurses related to the prevention of PU. FINDINGS: The mean scores of KAP of ICU nurses toward PU prevention were 70.57 (SD = 13.51), 52.82 (SD = 6.16), and 22.44 (SD = 5.20), respectively. There was a positive correlation between nurses' attitude and practice (r = 0.232, P = 0.002), and a negative correlation between knowledge and attitude (r = -0.156, P = 0.035) of nurses regarding PU prevention. Additionally, a positive correlation was found between nurses' years of working experience in ICU and their knowledge regarding PU prevention (r = 0.159, P = 0.032). CONCLUSION: According to the results of the present study, the level of KAP of Iranian ICU nurses related to PU prevention were desirable, positive, and relatively desirable. Therefore, nurse managers and policymakers should try to eliminate the main barriers such as heavy workload, inadequate nurse staffing, and lack of appropriate guidelines for PU prevention which consequently affect the practice of ICU nurses in the prevention of PU.

Knowledge, attitude, and practice of Iranian nurses towards pressure ulcer prevention: A systematic review.

INTRODUCTION: Pressure ulcer (PU), as a long-term disabling condition, is an important indicator for patient safety and quality of nursing care in hospitals. This systematic review aimed to evaluate the knowledge, attitude, and practice of Iranian nurses towards PU prevention. METHODS: A systematic search was conducted on PubMed, Web of Science, Scopus databases, Google Scholar Search Engine, as well as Magiran, Iranmedex, and Scientific Information Database (SID) Persian databases using the relevant keywords, from the earliest date available to August 21, 2020. Studies were appraised using the appraisal tool for cross-sectional studies (AXIS tool). FINDINGS: Among a total of 1,543 Iranian nurses included in the 9 studies, 80.53% were female with a mean age of 31.14 (SD = 5.52) years. The mean work experience of the participants was 7.94 years (SD = 5.44). The knowledge and practice of Iranian nurses toward PU prevention were insufficient and relatively desirable, respectively. Also, the present study showed that nurses' attitudes toward PU prevention were contradictory. Age, gender, level of education, work experience, and participation in previous educational workshops were possible factors related to nurses' knowledge about PU prevention. Women with higher work experience had a more positive attitude. CONCLUSION: This review found inappropriate knowledge, attitude, and practice of Iranian nurses toward PU prevention and highlights the importance of regular upgrading of nurses' knowledge and practice related to PU prevention.

Effective interventions for reducing moral distress in critical care nurses.

Moral distress (MD) has received considerable attention in the nursing literature over the past few decades. It has been found that high levels of MD can negatively impact nurses, patients, and their family and reduce the quality of patient care. This study aimed to investigate the potentially effective interventions to alleviate MD in critical care nurses. In this systematic review, a broad search of the literature was conducted in the international databases including PubMed/MEDLINE, Web of Science, and Scopus, as well as Google Scholar search engine using keywords such as moral distress, intensive care unit, ICU, nurses, and critical care nurses from 1984, when the concept of MD was first introduced in the nursing literature, up to 29 October 2020. Studies focusing on the interventions for managing MD in critical care nurse were evaluated. The quality of eligible papers was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. A total of 8 studies fulfilled the eligibility criteria. Three studies had RCT design and five studies had quasi-experimental design. All studies were conducted in the United States or Iran. Educational workshop, moral empowerment program, social work intervention, nursing ethics huddles, and multifaceted resiliency bundle intervention were effective interventions for managing of MD among critical care nurses. There is limited but promising research evidence evaluating the efficacy of educational interventions for managing of MD among critical care nurses. Although some positive results have been reported, there is limited generalizable evidence due to the variability of interventions. These findings highlight the need for further studies to validate the efficacy of these interventions or develop more potent and efficient interventions for reducing MD in critical care nurses.

The impact of laughter yoga on depression and anxiety among retired women: a randomized controlled clinical trial.

Recently, laughter yoga (LY) has been introduced for managing depression and anxiety. This study aimed to investigate the impact of LY on depression and anxiety among retired women in city of Bojnurd, Iran, 2018. Sixty-six retired women were randomly assigned to intervention and control groups. Intervention group received LY twice weekly for 8 weeks; control group had their routine daily activities. Depression and anxiety levels were measured at study initiation, week 4, and week 8 in both groups. Results showed significant difference in the pattern of depression (p <.001) and anxiety (p <.001) scores within and between groups. LY could be an effective intervention in reducing depression and anxiety among retired women.

A Systematic Review and Meta-analysis of Attitudes of Iranian Nurses and Related Factors Towards End-Of-Life Care.

This meta-analysis aimed to summarize the evidence regarding attitudes of Iranian nurses and related factors towards end-of-life (EOL) care. PubMed, Web of Science, Scopus, Magiran, Iranmedex, Scientific Information Database, and Google Scholar search engine were searched using Persian and English appropriate keywords from the earliest records up to September 11, 2020. A total of 849 nurses were included in six studies. After a meta-analysis of the mean score of nurses' attitudes, the pooled mean was 80.07 out of 120 (Q(5)=4.32, I-squared=0.00%; 95%CI: 73.53-86.60; p < 0.001). Marital status, ward type, education level, a history of participating in EOL care workshops, personal study of EOL care, experience of caring for a dying family member or close people, natural and approach acceptance, fear of death, and professional autonomy had a significant positive relationship with nurses' attitudes towards EOL care. Therefore, further large-scale studies considering potential confounding variables are needed to confirm our findings.

A Systematic Review of Death Anxiety and Related Factors Among Nurses.

This systematic review aimed to summarize the evidence regarding death anxiety (DA) and related factors among nurses. Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database (SID) databases were extensively searched using purpose-related keywords from the earliest to October 5, 2021. A total of 6819 nurses were included in 31 studies. The DA of nurses based on the Templer's Death Anxiety Scale was moderate. Factors such as personal anxiety, frequency and severity of job stress, burnout, dying patient avoidance behavior, euthanasia, sex, mental health status, social desirability, attitude toward the elderly, humor, social maturity, psychological hardiness, quality of life, lack of social activity, self-efficacy, coping with death, and life satisfaction were associated with nurses' DA. Therefore, nursing policymakers can promote nurses' health to improve the quality of nursing care by considering these related factors.

Bolus administration of intravenous lidocaine reduces pain after an elective caesarean section: Findings from a randomised, double-blind, placebo-controlled trial.

We conducted a randomised double-blind, placebo-controlled trial to assess whether a bolus dose of lidocaine during the induction of general anaesthesia would reduce postoperative pain over 24 h. Level of satisfaction with pain control at 48 h after surgery and Apgar score were also examined. A total of 100 women aged 20-35 years, who were candidates for elective caesarean section (CS) were randomised to receive either 1.5 mg/kg lidocaine or placebo during the induction of general anaesthesia. Results showed that lidocaine decreased pain intensity over 24 h after surgery (p < .001), and decreased postoperative morphine consumption from median (range) of 3.79 (0-9) mg in the placebo group to 0 (0-12) mg and in the lidocaine group (p <.001). Lidocaine was not associated with postoperative nausea and vomiting or any side effects in women and newborn babies. We conclude that a small bolus dose of lidocaine attenuates postoperative pain, thus reducing the requirement for opioid consumption in the postoperative period. Impact statement • With its anti-inflammatory, anti-hyperalgesic and analgesic properties, intravenous perioperative lidocaine infusion (IVLI) has been used for optimal postoperative care in different surgeries. Limited evidence suggests that IVLI may be a useful adjuvant during general anaesthesia. There is a report of a positive effect on several outcomes after surgery including postoperative pain over 24 h after laparoscopic abdominal surgery or open abdominal surgery. However, there was a paucity of information regarding the efficacy of a bolus dose of lidocaine in patients undergoing caesarean section (CS). In this randomized, placebo-controlled trial the use of a bolus dose of 1.5 mg/kg lidocaine 2%, compared with placebo, during the induction of general anaesthesia for elective CS resulted in a significant decrease in postoperative pain score as well as decreased postoperative morphine consumption over 24 h. Lidocaine use was not associated with any side effect in participants and newborns. • This study provides the first evidence that a bolus dose of lidocaine may be a safe and simple alternative therapeutic intervention for enhanced postoperative recovery in terms of pain and postoperative opioid consumption. Future studies are needed to examine pain reducing effect of perioperative bolus dose of lidocaine after CS under spinal or epidural anesthesia.

Comparing Hemodynamic Responses to Diazepam, Propofol and Etomidate During Anesthesia Induction in Patients with Left Ventricular Dysfunction Undergoing Coronary Artery Bypass Graft Surgery: a Double-blind, Randomized Clinical Trial.

BACKGROUND: Anesthesia induction is often accompanied by a period of hemodynamic instability, which could be deleterious in patients with coronary artery disease (CAD) and left ventricular dysfunction undergoing coronary artery bypass graft (CABG) surgery. The aim of this study was to compare the hemodynamic responses to propofol, etomidate, and diazepam following anesthesia induction, laryngoscopy and intubation in CABG surgery patients with low ejection fraction (EF). METHODS: A double-blind randomized, clinical study was performed on 150 patients with CAD and left ventricular dysfunction (EF≤35%) scheduled for elective CABG surgery with Cardiopulmonary bypass (CPB). Patients were randomly allocated to three groups A, B, and C. These patients received propofol, etomidate or diazepam at induction of anesthesia, respectively. Hemodynamic variables (systolic and diastolic blood pressure [SBP, DBP], mean arterial pressure [MAP] and heart rate [HR]) were measured and recorded at baseline, immediately before laryngoscopy and tracheal intubation and one and three minutes after intubation. RESULT: One minute after induction and before laryngoscopy, there was a statistically significant decrease from the baseline in SBP, DBP and MAP in all three groups, but these variables in each hemodynamic parameters in diazepam group were less than other two groups (p<0.001). Moreover, the mean HR decreased in patients receiving propofol and etomidate one minute after induction and before laryngoscopy, but did not decreased in the diazepam group (p=0.005). CONCLUSION: The present study showed that in patients undergoing CABG surgery with low EF, diazepam is more favorable in terms of hemodynamic stability compared to propofol and etomidate and this drug can be used safely for induction of anesthesia in patients with impaired ventricular function.

Zinc Supplementation in Adult Mechanically Ventilated Trauma Patients is Associated with Decreased Occurrence of Ventilator-associated Pneumonia: A Secondary Analysis of a Prospective, Observational Study.

BACKGROUND: Ventilator-associated pneumonia (VAP) is a type of lung infection that typically affects critically ill patients undergoing mechanical ventilation (MV) in the Intensive Care Unit (ICU). The aim of this analysis is to determine potential association between zinc supplementation with the occurrence of VAP in adult mechanically ventilated trauma patients. SUBJECTS AND METHODS: This secondary analysis of a prospective observational study was carried out over a period of 1 year in ICUs of one teaching hospital in Iran. A total of 186 adults mechanically ventilated trauma patients, who required at least 48 h of MV and received zinc sulfate supplement (n = 82) or not (n = 104) during their ICU stay, were monitored for the occurrence of VAP until their discharge from the ICU or death. RESULTS: Forty-one of 186 patients developed VAP, 29.09 days after admission (95% confidence interval [CI]: 26.27-31.9). The overall incidence of VAP was 18.82 cases per 1000 days of intubation (95% CI: 13.86-25.57). Patients who received zinc sulfate supplement have smaller hazard of progression to VAP than others (hazard ratio: 0.318 [95% CI: 0.138-0.732]; P < 0.0001). CONCLUSION: The findings show that zinc supplementation may be associated with a significant reduction in the occurrence of VAP in adult mechanically ventilated trauma patients. Further well-designed randomized clinical trials to confirm the efficacy of this potential preventive modality are warranted.

Does lidocaine as an adjuvant to morphine improve pain relief in patients presenting to the ED with acute renal colic? A double-blind, randomized controlled trial.

OBJECTIVE: Renal colic (RC) is a common clinical presentation in the emergency department (ED). Prompt and effective pain control is one of the first responsibilities of emergency physicians. The aim of this study was to evaluate the analgesic effect of adding lidocaine to morphine compared to morphine alone in patients presenting to the ED with RC. METHODS: In a double-blind, randomized controlled trial, a total of 110 adult patients of both sexes, aged 18 to 50 years, who presented to the ED with signs and symptoms suggestive of RC were randomly assigned into 1 of 2 groups. Patients in group A received morphine (0.1 mg/kg) plus lidocaine (1.5 mg/kg), whereas those in group B received morphine (0.1 mg/kg) plus normal saline 0.9% as placebo. All patients were asked to rate the intensity of their pain and nausea on a 0- to 10-point visual analog scale before and at 5, 10, 30, 60, and 120 minutes after intervention. RESULTS: There was a statistically significant time trend decline in both groups for both pain and nausea scores (P < .01). Repeated-measures analysis showed a significant effect for the interaction between group and time of persistent pain (P = .034), but there was no significant group effect in this regard (P = .146). Median times to being pain free in the group receiving morphine plus lidocaine and in the group taking morphine alone were 87.02 minutes (95% confidence interval [CI], 74.23-94.82) and 100.12 minutes (95% CI, 89.95-110.23), respectively (P = .071). Repeated-measures analysis also showed a significant group effect for nausea (P = .038), but there was no interaction between group and time in this regard (P = .243). The median nausea-free times in the group receiving morphine plus lidocaine and the group receiving morphine alone were 26.6 minutes (95% CI, 14.16-39.03) and 58.33 minutes (95% CI, 41.85-74.82), respectively. This time difference was statistically significant (P < .001). CONCLUSIONS: Using lidocaine may be recommended as an effective, safe, and inexpensive adjuvant to morphine in improving nausea and reducing the time needed to achieve pain and nausea relief in patients visiting the ED with acute RC.

Is Vitamin C Supplementation in Patients with ß-Thalassemia Major Beneficial or Detrimental?

Globally, ß-thalassemia major (ß-TM) is one of the most common hereditary disorders. Multiple blood transfusions, that are a life-saving therapy in patients with ß-TM, is a major source of iron overload. Iron overload can lead to significant morbidity and mortality. Research evidence indicates that oxidative stress induced by iron overload, is one of the major precipitating causes of vitamin C deficiency in ß-TM patients. It has previously been shown that patients with ß-TM have significantly lower levels of vitamin C as compared to healthy individuals. It is believed that vitamin C can reduce both ferric (Fe(3+)) and ferrous (Fe(2+)) ions, and also facilitate the accessibility of iron to chelators through increase of iron release from the reticuloendothelial system. Despite the potential benefits of vitamin C in patients with ß-TM, several areas of concern exist that should be addressed by high quality research designs. Some recommendations have been provided through this study.

Gastric Residual Volume: Rethinking the Threshold.

There are many challenges related to enteral feedings of the mechanically ventilated patient. Among the most often debated issues is the threshold for gastric residual volume before further feeding. This brief article considers the factors to be considered and reviews current thinking on the topic.
