BackgroundMechanical ventilation support can be the main source of ventilator-associated pneumonia (VAP). VAP is a serious infection that may be associated with dangerous gram-negative bacteria mainly, and it leads to an increase in the mortality in the intensive care unit (ICU). Imipenem is one of the strongest antibiotics now available for treating VAP which is associated with gram-negative and gram-positive bacteria, and it belongs to beta-lactam antibiotic group (carbapenem).ObjectiveThis study tried to investigate the efficacy of imipenem against VAP when it was infused within 180 min versus the efficacy when it was infused within 30–60 min.SettingThis study was conducted in main ICU in general hospital which consists of surgical and medical beds within 2 years. One hundred and eighty-seven patients were enrolled on it.MethodThis study is a retrospective cohort which was conducted within 2 years. The efficacy of imipenem which was administered by intermittent infusion (30–60 min) within first year was compared with the efficacy of imipenem which was administered by extended infusion (180 min) within second year in the field of VAP curing and cost reduction. All data were collected retrospectively from patient medical files and were statistically analyzed by SPSS version 20.Main outcomeThe study was designed to measure clinical and cost reduction outcomes, mortality and hospital stay.ResultsThe results indicated that there is a significant decrease in mortality, number of recurrent infection, and ICU stay length, and the number of mechanical ventilator days was associated with extended imipenem infusion during the second year of the study.ConclusionThe use of imipenem with extended infusion over 3 hours enhances its clinical outcomes in the treatment of VAP.
BackgroundThe intensive care unit (ICU) is a center of multidrug-resistant (MDR) pathogens. This is due to overuse of antibiotics in the treatment of critically ill patients. Tigecycline is a broad-spectrum antibiotic that belongs to the glycylcycline group. Tigecycline has been indicated in treatment of complicated intra-abdominal infections (cIAIs) and complicated skin and soft-tissue infections (cSSTIs).ObjectiveThis study was done to discover the best dose regimen of tigecycline in treatment of cSSTIs and cIAIs, especially in patients who are critically ill and obese, for clinical outcomes and safety.SettingThe study was conducted in an adult ICU that consists of 25 beds in a general hospital and was conducted within 2 years. A total of 954 patients were screened in this study.MethodsThis was a retrospective cohort study that compared the clinical outcomes of patients: mortality, ICU stay, and safety of using two different dose regimens of tigecycline between patients with different body weight who were treated for infections caused by MDR pathogens in the ICU. The study was conducted within 2 years. All results were collected from patients’ files and were analyzed with SPSS version 20.Main outcomeThe study was implemented to figure out the best dose regimen of tigecycline to achieve a reduction in mortality, ICU stay, treatment duration, and secondary septic-shock incidence with minimum side effects in treatment of cSSTIs and cIAIs in patients with different body weight.ResultsThere was a significant improvement in mortality, ICU stay, recurrent infection by the same organism, duration of tigecycline treatment, number of patients who had first negative culture after starting treatment, secondary bacteremia, and secondary septic shock with patients who used high-dose regimens of tigecycline in different subgroups of body weight, with no significant difference in side effects.ConclusionThe use of high-dose tigecycline resulted in a significant enhancement in all clinical outcomes, especially mortality and ICU stay when used in treatment of overweight and obese patients with cSSTIs and cIAIs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
