          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.
