Abstract

Background and OBJECTIVE: Rebound oedema of tissues is a well defined complication of cessation of steroid therapy. Tapering of systemic corticosteroid regimens in short course steroid therapy is considered unnecessary in most circumstances in acut exacerbation of chronic obstructive pulmonary diseases, presence of laryngeal rebound edema is obscure in this situtation. We studied whether or not laryngeal oedema increases after intubation when intubation is established after cessation of steroid therapy.METHODS: Thirty-six rabbits were randomly divided into six groups. We administered 1 mg/ kg methyl prednisolone intraperitoneally to four steroid groups for ten days. Another group received serum physiologic for ten days and last group was sham control that was intubated only. Rabbits that received steroid therapy were intubated and separated into groups one day, one week, two weeks, and a month after the cessation of steroid therapy. Airway area and percentage of cross sectional area of larynx lumen to their own larynx tissues surrounded by thyroid cartilage and oesophagus were studied by stereological methods. RESULTS: Larynx lumen area of one week steroid group was significantly narrower and percentage of cross sectional area of larynx lumen to their own larynx tissues surrounded by thyroid cartilage and oesophagus was significantly larger than sham control.CONCLUSION: Rebound oedema forms in larynx with abrupt cessation of steroid therapy in rabbits. Clinical safe time for intubation after abrupt cessation of steroid therapy is also defined with our study. These results suggest that one week after the cessation of steroid therapy may be a hazardous time for tracheal intubation.

Özet

Giriş ve AMAÇ: Dokulardaki rebound ödem, steroid tedavisinin kesilmesinin iyi tanımlanmış bir komplikasyonudur. Kronik obstruktif akciğer hastalığı akut alevlenmesinde, kısa süreli steroid tedavisinde sistemik steroidin kademeli olarak azaltılması çoğu durumlarda gereksiz görülür, bu durumda laringeal rebound ödemin varlığı araştırılmamıştır. Biz steroid tedavisinin kesilmesinden sonra entübasyon uygulandığında entübasyonun laringeal ödemi arttırıp arttırmadığını araştırdık. METOD: Randomize olarak 36 tavşan 6 gruba bölündü. Steroid uygulanan dört gruba on gün boyunca intraperitoneal 1 mg/kg metilprednizolon verildi. Bir gruba on gün boyunca serum fizyolojik verildi ve son kontrol grubu sadece entübe edildi. Steroid tedavisi verilen tavşanlar steroid tedavisinin kesilmesinden sonra 1.gün, 1. hafta, 2. hafta ve 1. ayda entübe edilerek gruplara ayrıldı. Havayolu alanı ve larinks lümeninin tiroid kartilaj ve özefagus ile çevrili larinks dokularına kesitsel yüzdesi stereolojik yöntemle çalışıldı. BULGULAR: Birinci hafta steroid grubunun kontrol grubuna göre larinks lumen alanları anlamlı olarak daha dardı ve larinks lümeninin tiroid kartilaj ve özefagus ile çevrili larinks dokularına kesitsel yüzdesi anlamlı olarak daha büyüktü.SONUÇ: Tavşanlarda steroid tedavisinin ani kesilmesinden 1 hafta sonra larinkste rebound ödem oluşur. Steroid tedavisinin kesilmesinden sonra intübasyon için klinik olarak güvenli zaman çalışmamızla tanımlanmıştır. Bu sonuçlar steroid tedavisinin kesilmesinden sonraki 1 haftalık sürecin entübasyon için riskli bir zaman olabileceğini düşündürmektedir.
