Abstract: (16715 Views)
Background and purpose: Laser bean produces thin incision along with hemostasis, sterility and decreased postoperative complications, hence facilitate air way surgery, but due to proximity of endotracheal tube to operation site, the risk of occupying and burning of endotrachel tube and surrunding tissues in each surgery is about 0.5% to 1.5%.
This study is about the complications arised by apnea technigue of general naesthesia and continued controlled ventilation with coated endothracheal tube, done in Tehran Âmir Âlam hospital in 1998-1999.
Materials and methods: Two groups of laser therapy candidates, each with 22 patients of 10 to 60 years of age and ÂSÂ 1 to 2 with less than 100kg weight, undergone anesthesia by the two above mentioned techniques. Both groups recieved the same anesthetic agent and mainteined in the same condition. Monitorings included electrocardiography (ËÇG, NÏBP) pulse oxymeter and capnograph.
Results: Hemodynamic changes were the same in both groups, hypoxia or arrythmia was not observed in any of the patients. Ïn the apnea technique operated patients, most of the surgical procdure was done in 2 to 3 a bneic episodes. Duration for each apnea was 2 to 4 minuts. Ïn the apnea technique group pet Ço2 was 38 to 47 mm Hg. Duration of laser therapy in apnea group was 9 to 10 minutes less than the coated tube group.
Çonclusion: Çonsidering the results of this study, in the apnea technique group there was no hypoxia arrythmia and threatening prolonged hypocapnia. Due to omition of endotrachial tube from the laser field, laser therapy would be done without any risk of fire and is done in the shorter time. The surgon would do a good and non risky surgery.
