Abstract

Background & Aim: The aim of this study was to compare air way resistance and dynamic compliance of tracheal tube and laryngeal tube in TIVA(Total Intravenous Anesthesia). Nowadays, low airway resistance and dynamic compliance improvement during the mechanical ventilation whether in ICU or during general anesthesia, especially in patients with pulmonary diseases, is a favorable purpose to control hemodynamic condition and prevent pulmonary barotrauma in patients. Besides airway control during CPR, providing airway for ICU patients or those who need intubation during anesthesia may cause damages because of laryngoscopy, and at the same time needs experienced personnel. Therefore, this investigation was undertaken to find a method through which no experienced personnel or laryngoscopy is needed, and besides which, airway resistance and dynamic compliance can be like the common standard methods.Patients & Methods: This clinical trial study was conducted on 34 patients(22 males and 12 females) aged between 16 to 53(33.1 age±12.4) with ASA(type I and II) who were candidates for orthopaedic surgery to reduce aspiration risk and were selected based on randomized simple sampling. In anesthesia by TIVA method(Total drugs which used IV), propofol was used as anesthetic, fentanyl as analgesic and pavolon as relaxant. Pavolon was used because it has least hystamin release and, therefore, has no effect on airway resistance. Airway resistance and dynamic compliance were measured by NICOME and CO2 in expiration.Results: The results were assessed by t-test and Pvalue<0.05 was observed between mean airway resistance in tracheal tube(7.38±1.55) and laryngeal tube(34.35±3.87). There was a significant difference between airway dynamic compliance in laryngeal tube(26.08±4.54) and tracheal tube(44.55±7.06). There was also a significant difference between cardiac output in use of tracheal tube(5.37±0.207) and laryngeal tube(4.605±0.34) which showed cardiac output was lower in laryngeal tube method.Conclusion: Although laryngeal tube is a suitable alternative in difficult intubation or CPR, high airway resistance and low dynamic compliance causes decline in cardiac output and pulmonary damage; therefore, it is not a suitable alternative in all cases.
