Endotracheal Intubation
Conditions
Brief summary
This study is prospective randomized trial study. O type tracheal intubation tube is anatomically consistent and will able to increase the success rate of first intubation without any other external help.
Detailed description
This study is divided into two groups. : control vs. O shape endotracheal tube. The investigator was studied 238 consecutive the American Society of Anesthesiologists' physical grades I and II adult patients scheduled to undergo general anesthesia requiring tracheal intubation for elective surgery. Exclusion criteria included a gross anatomical abnormality, before surgery of the head, neck and cervical spine, previously difficult tracheal intubation, loose teeth, or those requiring a rapid sequence or awake intubation, moderate or severe obstructive/restrictive pulmonary disease accompanied by pulmonary function tests. Anesthesia was induced with remifentanyl 3ng/kg, propopol 1-2 mg/kg or TIVA 2% fresopol 4ug/dL, remifentanyl 3ng/dL and rocuronium 0.8 mg/kg to facilitate tracheal intubation. Laryngoscopy was performed after the loss of the fourth twitch in the train-of-four in response to ulnar nerve stimulation. All laryngoscopies using a #4 Macintosh blade were performed with the patient placed in the sniffing position. Tracheal intubation was performed without assistance (ex. External laryngeal manipulation, Used stylet). A single experienced anesthesiologist, blinded to each group, performed all of the direct laryngoscopies and classified the laryngoscopic view according to the modified Cormack and Lehane grade, measured number of attempts, intubation time and blood pressure and heart rate before/ after intubation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| First intubation success rate for each between two group | Immediately after intubation | First laryngoscope tries was success using detection of end tidal CO2 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| First intubation time | within 60 seconds | After intubation, appearing end tidal CO2 at monitoring |
| Number of attempts | From the first tracheal intubation failure to the next successful tracheal intubation | Number of intubation try |
| Measured vital sign | immediately before intubation and within 5 minites after intubation | Blood pressure in mmHg and heart rate in bpm were recorded immediately before and after intubation. |
