Summary
Brief summary (as posted)
Double lumen tubes (DLT) have become standard of care for one lung ventilation in thoracic and esophageal surgeries. Selection of accurate size of DLT is important to achieve proper one lung ventilation, prevent trauma to airway, easy intubation, prevention of displacement of DLT and adequate oxygenation intraoperatively. There are no definitive guidelines to select the correct size of DLT. The aim of this study is to observe if there is any difference in the number of intubation attempts, intraoperative oxygenation and postoperative sore throat while using 35 Fr DLT size and other DLT size. The research will be conducted between Ashoj 1st 2082 to Chaitra 30 2082 at Manmohan Cardiothoracic Vascular and Transplant Center(MCVTC). Fifty patients aged more than eighteen years undergoing thoracic surgery requiring One Lung Ventilation(OLV) with left sided DLT will be selected for the study. Participants will be randomly assigned to 35 Fr DLT size group or DLT size group according to the height. Patients in both the groups will be given the samepreoperative care, intraoperative care and postoperative care. Besides patient's demography, diagnosis and operative procedure; number of intubation attempts, modified Cromack-Lehane(CL) grade, size of DLT, intraoperative oxygen saturation SpO₂ and postoperative sore throat on day of surgery and first postoperative day will be recorded. Statistical analysis will be done using t- test for independent variable, confidence interval for outcome of sore throat, significance of difference for number of male and female; rates, risk ratio and odds ratio will be calculated using 2x2 contingency table. P ≤ 0.05 will be considered statistically significant. Our expected outcome is 35 Fr DLT are easier to intubate, does not affect intraoperative oxygenation and decrease the incidence of postoperative sore throat.

- Ease of intubation using a 35 Fr DLT
- timeFrame
- Day 1
- description
- Ease of intubation is assessed using "number of intubation attempt and "Cormack-Lehane grade" that will be determined by anaesthesia provider who is intubating. The number of intubation attempt is the tube pass attempt during intubation and Cormack-Lehane grade is the percentage of vocal cord structure visualized during direct laryngoscopy. Number of intubation attempt and cormack-Lehane grading will be recorded in the proforma of the study.
