| Introduction & Objective: In some medical situations administration of muscle relaxants after intravenous anesthetics for tracheal intubation may be unnecessary or sometimes could be hazardous. In such situations, replacing an alternative drug for the facilitation of tracheal intubation is obvious. Remifentanil is a short acting opioid drug which may be useful in solving this problem. The aim of this study was to compare the effects of propofol or thiopental in combination with remifentanil in the absence of muscle relaxants on larengoscopy and intubation conditions in general anesthesia.
Materials & Methods: This is a randomized double-blind clinical trial which was performed in 1386 in Be’sat hospital of Sanandaj. Forty two ASA 1 and 2 patients recruited to receive propofol, 2 Mg/Kg, or thiopental, 5Mg/K. All patients received lidocaine, 1.5 Mg/Kg, and remifentanil, 2.5 µg/Kg, 30 seconds before anesthetics administration. larengoscopy and tracheal intubation were done 90 seconds after induction of anesthesia. On the basis of mask ventilation, jaw relaxation, vocal cords position and patient's response to intubations and endotracheal tube cuff inflation the intubation conditions were assessed and recorded as excellent, good ,acceptable or poor. The mean arterial pressure and heart rate were measured before and after anesthetics administration and also 45 seconds and two and five minutes after intubations. Data were analyzed by X2, fisher exact test ant student T-test using SPSS software.
Results: Excellent or good larengoscopy and intubation conditions were observed in 9 (%42.9) of thiopental patients and 20 (%95.2) of propofol patients (p<0.05). Mean arterial pressure and heart rate decreased more significantly in propofol group in comparison with the thiopental group (p<0.05).
Conclusion: Combination of remifentanil and propofol or thiopental could facilitate ventilation via face mask in all patients. Although combination of propofol and remifentanil is better than thiopental and remifentanil for tracheal intubation without muscle relaxants, it induces more homodynamic changes. |
