Abstract:

          Suction of endotracheal tube in ICU can cause hemodynamic    changes. We compare the effect of lidocaine , fentanyl and placebo on    reducing hemodynamic changes following suction in ICU patient.           Patients were divided into three groups , each containing twenty two    patients: A- Lidocaine group receiving 1.5 mg/kg lidocaine intravenously    two minutes before suction , B- Fentanyl group receiving 3 mg/kg fentanyl    two minutes before suction , C- Placebo receiving distilled water . The    total volume of the three substances  was raised to 5 cc. Injecting the drugs    and suctioning in a standard technique , we recorded mean arterial    pressure , pulse rate , arterial oxygen saturation three times : immediately ,    after three and six minute’s . The recorded information was analyzed.           Based on the results , the injection of Lidocaine before suctioning    prevented the hemodynamic changes and hypoxemia , which happened    after endotracheal suction. Fentanyl caused hypotension and bradycardia ,    rejecting the previous reported research. Suctioning in the placebos    resulted in hypotension , bradycardia and hypoxemia.           We can use intravenous lidocaine before endotracheal suction to    prevent hemodynamic changes in ICU patients.

تأثیر بازآموزی ساکشن لوله داخل تراشه برای پرستاران، بر تغییرات فشارخون بیماران بستری در بخش مراقبت ویژه

Background & Aim: Endotracheal suctioning (ETS) is a common invasive nursing procedure. Hemodynamic parameters changes during and after the procedure. If appropriate strategies do not be applied during the ETS, hemodynamic changes can be significant and life threatening in critically ill patients. The purpose of this study was to assess the effect of education of endotracheal suctioning on pati...

مقایسه تاثیر پروپوفول و تیوپنتال بر تغییرات همودینامیک و طول مدت توقف تنفسی به دنبال قرار دادن لوله تراشه در بیماران بستری در بخش مراقبت های ویژه

Background:Use of drugs with short apnea duration and less hemodynamic changes for intubation of trachea in intensive care units is necessary. This study compares the effects of propofol and sodium thiopental on hemodynamic changes and apnea duration after tracheal intubation in patients admitted to intensive care units. Methods:In this double blind clinical trial, 25 ICU-admitted patients were...
