title: Hemodynamic response to endotracheal intubation using C-Trach assembly and direct laryngoscopy.
abstract: OBJECTIVE
  Our objective was to study the pressor response to endotracheal intubation through laryngeal mask airway C-Trach and compare it to the hemodynamic response to intubation with direct laryngoscopy (DL).
  
  
  METHODS
  After obtained approval from institutional ethical committee, 100 patients of American Society of Anesthesiologists physical Status I, aged 14-65 years, posted for elective surgery were enrolled in the trial. They were randomly divided into two groups of each 50 patients. Anesthesia technique was standardized and patients of Group I were intubated using DL, while patients of Group II were intubated with the help of C-Trach assembly. Hemodynamic parameters, systemic blood pressure (systolic and diastolic) and heart rate were recorded before and after induction of anesthesia and every minute up to 5 min after intubation.
  
  
  RESULTS
  Patients of Group II recorded a minimal rise in peak systolic blood pressure (SBP) (1.8%) and diastolic blood pressure (10.6%). In comparison patients of Group I recorded a significant sustained rise in peak SBP (20.3%) and diastolic blood pressure (21.4%). However heart rate changes recorded in the two groups were of equal measure (peak rise of 22.9% in Group I vs. 22.4% in Group II).
  
  
  CONCLUSIONS
  We conclude that intubation through C-Trach generates a lower pressor response to intubation in comparison to intubation using DL.
