Background: The patient’s position is important for ensuring patient comfort and preventing complications after thyroidectomy. Objectives: This study was carried out to determine the effects of different degrees of head-of-bed elevation (HOBE) on the respiratory pattern and drainage following thyroidectomy and to provide suggestions for evidence-based clinical practice. Methods: The sample of this prospective, parallel arm, randomized controlled trial included 114 patients undergoing thyroidectomy in a university hospital in Turkey. The patients were randomly assigned (1:1:1) to supine 0° (baseline), 30° and 45° HOBE groups. Respiratory pattern including respiratory rate (RR), peripheral oxygen saturation (SpO2 ) and dyspnea, and drainage including amount of drainage and hematoma formation were evaluated at the 1st, 2nd, 3rd and 4th hours following thyroidectomy. Results: The majority of the patients (83.3%) were female and 84.2% had undergone total thyroidectomy. The mean RR (18.47, 95% CI=17.85-19.09) of the patients in the supine 30° HOBE group at the 1st hour was significantly higher than that of the patients in the supine 0° group (17.32, 95% CI=16.88-17.76; p<0.05). There was no significant difference between the SpO2 values of the patients in the groups (p>0.05). The amount of drainage was significantly higher in the supine 0° group at the 2nd hour than that of the patients in the supine 45° HOBE group (5.92±5.18; 3.34±5.56 respectively; p<0.05). None of the patients in the groups had hematoma formation. While no patient in the supine 30° HOBE group had dyspnea, dyspnea occurred in 9 patients in the supine 0° group and in 3 patients in the supine 45° HOBE group. Conclusion: This study showed that different HOBE positions resulted in clinically insignificant changes on the RR and amount of drainage during the first 4 hours following thyroidectomy but did not affect SpO2 value.
