Meanwhile, aspiration around ETT in patients undergoing adenotonsillectomy is concerned.We compared cuffed versus uncuffed ETT regarding respiratory complications following adenotonsillectomy. </p><p> <strong>Methods:</strong> 128 children aged 2-8 yr were divided to two groups of 64 each. Uncuffed and cuffed tubes were used respectively in the uncuffed (UG) and cuffed (CG) groups. Anesthesia was routinely performed in a identical pattern in all patients. The number of attempts to reach the appropriate tube size was recorded. After extubation, the patients observed for the occurrence of cough, hypoxemia, and stridor. </p><p> <strong>Results:</strong> Less reintubation attempts were needed in the CG (p.value=0.002). In the UG, 31.3% and in the CG 10.9% had some respiratory complications (P.value=0.009). The change of the initial tube had significant effect on the occurrence of croup and stridor (P.value= 0.000). </p><p> <strong>Conclusion:</strong> The use of cuffed tube in 2-8 yr, could lower the incidence of respiratory </p><p> complications following adenotonsillectomy. It also decreases the number of intubation attempts needed to reach the appropriate tube size. </p><p>  </p><p>  </p> Adenotonsillectomy, tracheal intubation, cough, hypoxemia,stridor, ndotracheal tube, cuff, postoperative 151 158 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-119&slc_lang=en&sid=1 Behzad Maghsoudi maghsodb@sums.ac.ir 2003194753284600872 2003194753284600872 Yes Department of Anesthesiology, Khalili hospital, Shiraz University of Medical Sciences, Shiraz, Shojaolhagh Tariq drtariqsuh@yahoo.com 20031947532846001043 20031947532846001043 No Department of Anesthesiology, Khalili hospital, Shiraz university of medical sciences, Shiraz, Iran Seyed Basir Hashemi hashemib@yahoo.com 20031947532846001044 20031947532846001044 No Department of ENT , Khalili hospital, Shiraz university of medical sciences,Shiraz,Iran Masoud Kaviani Kaviani00@gmail.com 20031947532846001045 20031947532846001045 No Department of ENT , Khalili hospital, Shiraz university of medical sciences,Shiraz,Iran
