| Abstract | INTRODUCTION: Tracheal intubation using a laryngoscope is considered to be the Gold standard of airway management during administration of general anaesthesia and in critical care settings because of its several advantages including: • Allows delivery of anaesthetic gases and oxygen via positive pressure ventilation without inflation of stomach. • Isolation of the respiratory tract from GI system and hence minimal risk of aspiration. • Access to tracheobronchial tree for pulmonary hygiene and drug administration(e.g.inhaled bronchodilators). • Improved surgical access to head and neck. Airway management is important in anaesthesia because adverse respiratory events are responsible for 75% of ASA closed claims. Of these inadequate ventilation is the main culprit(38%), followed by oesophageal placement of tracheal tube(17%) and difficult intubation (18%). Approximately 600 patients die each year in the developed world from complications related to airway management and the scenario in the underdeveloped world is much grimmer. AIM OF THE STUDY: To compare the intubating conditions with Airtraq laryngoscope and Macintosh laryngoscope in respect to • Advantages and safety. • Effective intubation time. • Airway trauma. METHODOLOGY It was a Prospective, Randomized, Single blinded (subject), Case control study conducted in the Institute of Anaesthesiology and Critical Care, Madras Medical College and Government General Hospital, Chennai. 60 adult patients satisfying inclusion criteria were enrolled in the study after obtaining informed consent. INCLUSION CRITERIA: • Elective adult surgical patients requiring general endotracheal anaesthesia. • Males and females. • ASA physical status 1,2 & 3. • Age 18 years of age and older. • Who have given valid informed consent. EXCLUSION CRITERIA: • Healthy volunteers. • Not satisfying inclusion criteria. • Patients requiring special techniques for intubation such as rapid sequence induction. • Intubated prior to surgery. • Severe cardiovascular, hepatic or renal disease, mental illness. • Are unconscious or very severely ill, ASA physical status IV. • Need for nasal intubation. MATERIALS: • Macintosh laryngoscope- current standard device • Airtraq laryngoscope device- used during laryngoscopy to facilitate intubation. • Weighing machine calibrated to 1 kg. • Measuring tape calibrated to 0.5 cm. • Goniometer. OBSERVATION AND RESULTS: This prospective, randomized, single blind (subject), case controlled study compared the intubating conditions with Airtraq laryngoscope and Macintosh laryngoscope and evaluated the advantages and safety, effective airway time, airway trauma and hemodynamic response. All data were collected and tabulated. DEMOGRAPHIC VARIABLES: 60 patients were randomly selected and included in this study. Thirty patients were randomly assigned to undergo tracheal intubation with Airtraq laryngoscope (Group A) and thirty underwent tracheal intubation with Macintosh laryngoscope (Group B). Mean age, sex distribution and Body Mass Index of the patients in both the group were compared and there were no statistically significant differences between the groups. CONCLUSION: In conclusion, the Airtraq laryngoscope offers a new approach to tracheal intubation of patients with anticipated and unanticipated difficult airway. The Airtraq reduced the difficulty of tracheal intubation and the degree of hemodynamic stimulation compared with the Macintosh laryngoscope. These findings demonstrate the efficacy of the Airtraq in many clinically relevant contexts and adds to the evolving body of knowledge regarding this potentially useful device. |
