    Comparison of the lateral decubitus and beach chair positions in terms of their effects on airway pressure in arthroscopic shoulder surgery
    (2019) Duman Aydin, Pinar; Saylan, Sedat; Besir, Ahmet; Gul, Orkun
    Aim: The aim of this study was to investigate the effects of extravasated fluid on the airway pressure of the patients in different surgical positions.Material and Methods: This prospective observational study included 50 arthroscopic shoulder surgery patients (18-65 years) placed in lateral decubitus (Group L) and beach chair (Group B) positions under general anesthesia. Peak airway pressure (Ppeak) and internal PEEP (iPEEP) measurements were recorded after intubation. The neck, chest, and shoulder circumferences were measured before induction and after operation.Results: The increases in Ppeak and iPEEP values were not statistically significant between the groups (p> 0.05). The total amount of irrigation fluid was significantly higher in Group L (p=0.042), not significantly correlated with Ppeak but positively correlated with the surgery time (r=0.51099; p=0.001 0.05). The neck circumference measurements were statistically significant between the groups. No respiratory complications were observed during the follow-up period.Conclusion: The lateral decubitus and beach chair positions do not cause a clinically significant compromise on the airway pressure in arthroscopic shoulder surgery but a longer operation duration will cause a higher amount of irrigation fluid to be used, leading to an increased circumference of the neck in the postoperative period.Keywords: Shoulder arthroscopy; airway pressure; lateral decubitus position; beach chair position

    Objectives: This study aims to compare the measurements using biochemical markers of bone turnover and bone mineral density (BMD) in the assessment of the efficiency of osteoporosis treatment. Patients and methods: Between March 2006 and December 2008, 166 patients with osteoporosis in our clinic were included. Patients who were out of contact due to death or other reasons during follow-up were excluded. We compared the measurements of urinary biochemical markers of bone turnover using cross-linked N-telopeptide (Ntx) values and BMD in 60 patients (49 females, 11 males; mean age: 65.7 years; range: 42 to 87 years) with osteoporosis who were treatment-naive and completed study. Results: Twenty-nine (48.3%) of the patients received surgical treatment, while 31 (51.7%) received conservative therapy. Urine NTx values of the patients decreased 38.82% at three months; 51.99% at six months and 66.41% at 12 months. Lumbar vertebra BMD increased by 20.7% and femur neck BMD increased by 11.9% at the end of the first year. Conclusion: Urine NTx values respond to osteoporosis treatment faster than BMD measurements; thereby it may be suitable to use this parameter for the monitorization of the treatment efficiency.
