Özet:

 Purpose: Spinal anesthesia disrupts the bodys thermoregulatory response, often leading to undesired perioperative hypothermia 36ºC, especially in major surgeries such as total knee arthroplasty TKA. In operating rooms with a laminar airflow system LAS-OR, the airflow direction differs from conventional airflow systems CAS-OR by being directed directly onto the surgical table. The aim of this study is to answer the question, Does laminar airflow in the operating room during total knee arthroplasty lead to more perioperative hypothermia compared to conventional airflow? Materials and Methods: This study is a prospective, randomized controlled trial. Patients were divided into two groups, Group L operated in LAS-OR n110 and Group C operated in CAS-OR n110, using simple randomization with sealed envelope method. The frequencies of perioperative hypothermia IPH were compared between the groups. Clinical trial registration numberdate: IRCT20180324039145N4  2018.10.31 Results: In Group L, data from 94 patients and in Group C, data from 89 patients were evaluated. During TKA, the frequency of perioperative hypothermia IPH was 56.8 104 out of 183 patients, with no statistical difference found between Group L and Group C 62.8 59 out of 94 patients vs. 50.6 45 out of 89 patients, p0.096. At the 105th minute, Group L experienced a temperature decrease of 0.76 0.47 ºC 95 CI: 0.61 to 0.91, whereas Group C had a temperature decrease of 0.74 0.51 ºC 95 CI: 0.58 to 0.90, with no significant difference observed p0.823. Conclusion: There is no difference in the frequency of perioperative hypothermia IPH between operating rooms with laminar and conventional airflow during total knee arthroplasty under spinal anesthesia.

 Amaç: Spinal anestezi vücudun termoregülatuar yanıtını bozar, sıklıkla özellikle total diz artroplastisi TKA gibi major cerrahilerde istenmeyen perioperatif hipotermi İPH 36ºC gelişmesine neden olur. Laminar havaakım sistemli ameliyat odalarındaki LAS-OR hava akımının yönü, konvensiyonel havaakım sistemli ameliyat odalarındakinin CAS-OR aksine, doğrudan ameliyat masasına doğrudur. Bu araştırmadaki amacımız  Total diz artroplastisi sırasında ameliyathanedeki laminar havaakımı klasik havaakımından daha fazla perioperatif hipotermiye neden olur mu? sorusunu cevaplamaktır. Araçlar ve Yöntem: Bu çalışma prospektif, randomize kontrollü bir araştırmadır. Hastalar grup L LAS-OR da ameliyat edilenler n110 ve grup C CAS-ORda ameliyat edilenler n110 basit randomizasyonla, kapalı zarf metodu kullanılarak iki gruba ayrıldı. İPH frekansları karşılaştırıldı. Clinical trial kayıt numarasıtarih: IRCT20180324039145N4  2018.10.31 Bulgular: Grup Lde 94 hastanın grup Cde 89 hastanın verileri değerlendirildi. TKA sırasında İPH frekansı 56.8 iken 183 hastanın 104ünde, grup L ve grup C arasında istatiksel fark bulunmamıştır  62.894 hastanın 59u  50.6 89 hastanın 45i, p.096. Yüz beşinci dakikada, grup Lde 0.76 0.47 ºC 95CI 0.61 to 0.91 sıcaklık azalması varken buna karşı grup Cde 0.74 0.51 ºC  95CI 0.58 to 0.90, p.823 sıcaklık azalması bulunmuştur. Sonuç: Spinal anestezi altında total diz artroplastisi sırasında laminar ve konvensiyonel hava akımlı odalardaki İPH frekansları arasında fark yoktur.
