Abstract
- The coaxial circle system helps prevent heat loss during surgery, and it also acts as a humidifier. This study aimed to compare the coaxial breathing system and the conventional system in their ability to warm and moisturize inhaled gases, and we also analyzed lung function protection and saccharin clearance time in patients who underwent tympanomastoidectomy (TMT) with the aid of these two systems.Forty adult patients of ASA physical status I-II were scheduled for elective TMT. A standard volume-dependent ventilator setting was used to establish normocapnia. The coaxial circle system was used in the treated group (n=20), whereas the conventional circuit system was used in the control group (n=20). Saccharin clearance, VC (vital capacity), FRC (functional residual capacity), FEV1 (forced expiratory volume in 1 second), airway pressure, relative humidity and temperature of inspired gas, body temperature and adverse and hemodynamic effects were measured at different perioperative periods.The relative humidity (mg H2O Lt -1) of inspired gas in the treated group was higher than in the control group at 5, 15, 30, 45, 60 and 90 minutes after anesthesia induction. The temperature of inspired gas (Centigrade) in the treated group was higher than in the control group (p0.05) after 5, 10, 15, 30, 45, and 90 minutes of anesthesia. Postoperative saccharin clearance time was lower than before the operation in the treated group (p0.05). Postoperative FRC was lower than preoperative FRC in the study and control groups (p0.05).The coaxial circle system decreased postoperative saccharin clearance time and increased postoperative FRC, relative humidity and the temperature of inspired fresh gas, without any adverse perioperative effects in patients who underwent TMT.Koaksiyel halka sisteminin kullanılması cerrahi sırasındaki ısı kaybını önler. Ki o bir nemlendirici olarak rol oynar. Bu çalışma timpanomastoidektomi (TMT) operasyonu geçiren hastalarda Konvensiyonel sistem ve koaksiyel sistemin, sakarin klirens zamanı ve akciğer fonsiyon testlerinin korunması ve inhale edilmiş gazın ısınma ve nemlenmesinin karşılaştırılmasını amaçlamıştır.Elektif timpanomastoidektomi yapılan ASA I–II fiziksel statüsünde yetişkin 40 hasta seçildi. Normokapniyi sağlamak için standart volüm ayarlı ventilatör kullanıldı.Tedavi grubunda (n=20), koaksiyel halka sistemi, kontrol grubunda (n=20) Konvensiyonel halka sistemi kullanıldı. Farklı peroperatif dönemlerde, Sakkarin klirens zamanı, VC, FRC, FEVİnspire edilmiş gazın nisbi nemi anestezinin 5, 10,15, 30, 45 ve 90. dakikalarında tedavi grubunda kontrol grubundan daha yüksek bulundu. İnspire edilmiş gazın ısısı anestezinin 5, 10,15, 30, 45 ve 90. dakikalarında tedavi grubunda kontrol grubundan daha yüksek bulundu (p0.05). Tedavi grubunda postoperatif sakkarin klirens zamanı preoperatif değerden daha düşük bulundu (p0.05). Çalışma ve kontrol grubunda postoperatif FRC preoperatif FRC’den daha düşüktü.TMT yapılan hastalarda Koaksiyel halka sistemi herhangi bir peroperatif yanetki yapmadan Postoperatif sakkarin klirens zamanını azaltmış, inspire edilmiş taze gazın postoperatif FRC’yi, nisbi nemini ve ısısını arttırmıştır.
