ICU nurses in Iran may face many challenges in gaining professional autonomy. The identified inter- and intraprofessional barriers to the exercise of autonomy need to be addressed to promote critical thinking, job satisfaction, and motivation of ICU nurses, which can in turn lead to improved patient outcomes.
The aim of this study is to identify the antibiotic sensitivity pattern of pathogens involved in the process of surgical site infection, in surgical wards. Changes made in the pattern of antibiotic use will result in different microorganism susceptibility patterns, which needs correct determination for precise empiric antibiotic therapy. One thousand patients (62% men and 38% women, 18- 74-years-old, with mean age 43 +/- 8)) who underwent surgical treatment, in Alzahra University Hospital, Isfahan University of Medicine, Isfahan, Iran, were studied from 2005 to 2006. Surgical wound infections, based on the reported criteria, were aspirated for culturing within 1 plus gram staining of prepared smears. Minimum Inhibitory Concentrations (MICs) were determined for samples and all derived data were compared by SPSS 13 and WHO net 5 software. The prevalence of SSI was 13.3% with 150 positive cultures, totally. Of 150 bacteria, isolated from surgical site infections Staphylococcus aureus had most frequency (43%). Resistance of isolated organisms was 41.7% in amikacin, 65 and 78.6% in ceftazidime, 85.7% in ceftriaxone, 61.5% in ciprofloxacin, 78.8% in gentamicine, 6.4% in imipenem, 13% in meropenem and 70.6% in trimethoprim/sulfamethoxazole, respectively. 78.9% of Staphylococcus aureus isolates were MRSA and vancomycine was the most effective antibiotic without any resistance. Among 10 isolates of coagulase negative Staphylococcus, no vancomycine resistance was seen, but in contrast all cases were resistant to oxacillin. The most common gram negative organism was Klebsiella (18 isolates) in which 100 and 80% were sensitive to imipenem and meropenem, respectively. Seventeen cases were E. coli, in which the most sensitivity was to meropenem (80%) and imipenem (77.8%). Thirteen cases of Pseudomonas were detected, in which 16.7% were resistant to imipenem and 8.3% to meropenem. Our results demonstrated that the total antibiotic resistance is increasing among SSIs, with an up sloping pattern, which will contact with a constant empiric antibiotic therapy. So, precise up to date antibiogram tantalize us toward balancing the rate of total antibiotic resistance to SSIs.
Background:Pneumonia is one of the most common hospital-acquired infections among bedridden patients in Intensive Care Units (ICUs). Colonization of mouth and pharynx by pathogenic bacteria and their aspiration into the lower respiratory tract is an important step in pathogenesis of hospital-acquired pneumonia. The purpose of this study was to compare the effects of chlorhexidine and potassium permanganate mouthwashes in preventing incidence of hospital-acquired pneumonia in hospitalized patients in the ICU.Methods:This study is a clinical trial, conducted on 150 patients on ventilator in ICU. Patients were divided into three groups: Chlorhexidine group, potassium permanganate group, and control group. Mouthwashing three times a day, each time 5 min for 1 week by sterile gas with 10 cc solution of chlorhexidine, potassium permanganate, or placebo, was performed. Finally, pneumonia incidence was recorded, according to the Center for Disease Control and Prevention criteria. The data were analyzed by SPSS software version 20.Results:In the present study, 28 cases of pneumonia among 150 patients on ventilator were investigated. There were 15 (30%), 6 (12%), and 7 (14%) incidences of pneumonia in control, chlorhexidine, and permanganate group, respectively. Pneumonia incidence in these groups differed significantly (P = 0.041).Conclusions:The use of common mouthwashes, especially chlorhexidine solution, for washing oropharynx of ICU patients, can decrease pneumonia incidence, especially in patients under ventilation. Thus, washing and sterilizing mouth of patients with mouthwashes is recommended due to the high risk of hospital-acquired pneumonia in these patients.
BackgroundManagement of difficult to wean patients is a dilemma for health care system. Recently published studies demonstrated efficacy of donepezil to counteract respiratory depression in sleep apnea. However, to the best of our knowledge, pharmaceutical interventions with donepezil to facilitate weaning have not been tested so far. Therefore in the present study, we evaluated the efficacy of using donepezil on weaning course in difficult to wean patients.MethodsIn this non-randomized interventional clinical study, difficult to wean patients with prior inappropriately depressed respiratory responses were included from two referral intensive care units (ICU) in Iran. Patients with another potentially reasons of weaning failure were excluded from the study. Donepezil was started for eligible patients at dose of 10 mg daily for 2–4 weeks. For the primary outcomes, arterial blood gas (ABG) parameters were also measured before and after intervention to evaluate the possible effects of donepezil on them. In addition, weaning outcomes of patients were reported as final outcome in response to this intervention.ResultsTwelve out of 16 studied patients experienced successful results to facilitate weaning with donepezil intervention. The mean duration of donepezil treatment until outcome measurement was 12 days. There were not any significant differences in ABG parameters among patients with successful and failed weaning trial on day of donepezil initiation. However after donepezil intervention, mean of PCO2 and HCO3 decreased in patients with successful weaning trial and mean of PCO2 increased in those with weaning failure.ConclusionsReduced central respiratory drive was infrequently reason of failed weaning attempts but it must be considered especially in patients with hypercapnia secondary to inefficient gas exchange and slow breathing. Our results in the clinical setting suggest that, the use of donepezil can expedite weaning presumably by stimulation of respiratory center and obviate the need to re-intubation in cases of respiratory drive problem in difficult to wean patients. We suggest decrease PCO2 and HCO3 during donepezil steady could be valuable predictors for positive response to donepezil intervention.
