Abstract

We compared gastric distension, regurgitation and arterial blood gas tensions with laryngeal mask airway (LMA) or endotracheal tube (ETT) during laparoscopic cholecystectomy. Ninetytwo ASA I-II adults were scheduled, patients with risks of gastroesophageal reflux were excluded. Patients ingested methylene blue capsules 10 minutes before the induction of anesthesia. After the induction of anesthesia, a nasogastric tube was passed to decompress the stomach before insertion of the LMA (women size 3, men size 4) in Group LMA (n=46) or ETT (women 7.5 mm, men 8.5 mm) in Group ETT (n=46). Anesthesia was maintained with sevoflurane (2-3 %) and N2O; O2 (4;2 L/min). Gastric distention was scored on a scale of 0-10 at insertion of the laparoscope and immediately before removal. Hypopharynx was inspected for blue dye, considered to be sign of gastric regurgitation at the end of the operation. Blood gas analyses were performed before and at the end of pneumoperitoneum. Incidence of gastric distension and blue dye was similar in both groups (Blue dye being 12 % in both groups). Mean ETCO2 values were decreased significantly within the groups and there was no difference between the groups (p0.05). Mean pH values were decreased (p

Özet

Çalışmamızda, laringeal maske (LMA) ve endotrakeal tüp (ETT) ile pozitif basınçlı solunum uyguladığımız laparoskopik kolesistektomi olgularında mide distansiyonu, regürjitasyon gelişme sıklığı ile arter kan gazı sonuçlarını karşılaştırmayı amaçladık. Elektif laparoskopik kolesistektomi uygulanacak, ASA I-II risk grubunda 92 hasta çalışma kapsamına alındı. Gastroözafajial regürjitasyon riski olan hastalar çalışma dışında bırakıldı. Olgulara anestezi indüksiyonundan 10 dakika önce metilen mavisi kapsülleri içirildi. Tiyopenton, fentanil ve rokuronyum ile indüksiyondan sonra, Grup LMA'da (n=46) LMA (kadında 3, erkeklerde 4 numara), Grup ETT'de (n=46) ETT (kadında 7.5, erkekde 8.5 numara) yerleştirilmeden önce, nazogastrik sonda ile mide hava-sıvısı aspire edildi. Anesteziye O2 (2 L/dk) ve N2O (4 L/dk) beraberinde sevofluran ile devam edildi. Mide distansiyonu ameliyatın başlangıcında ve sonlanmadan hemen önce 1-10 olarak skorlandı. Ameliyat başlangıcında ve CO2 insüflasyonunun sonunda, SaO2, arter kan gazı ve ETCO2 basınç değerleri kaydedildi. Ameliyat sonunda direkt laringoskopi ile hipofarinksde mavi boya varlığı araştırıldı. Mide distansiyonu ile boyanma sıklığı her iki grupta benzer bulundu (boyanma, her iki grupta % 12) (p>0.05). Ortalama ETCO2 değerleri her iki grup içinde anlamlı artarken, gruplar arasında anlamlı fark izlenmedi (p0.05). Her iki grup içinde ortalama pH değerlerinde anlamlı azalma, ortalama PaCO2 değerlerinde anlamlı artış izlendi (p
