Comparison of efficacy of orotracheal intubation after rapid induction and nasotracheal intubafion after slow induction assisted by fiberoptic bronchoscope in patients with obstructive sleep apnea syndrome / 中华麻醉学杂志

Objective To compare the efficacy of orotracheal intubation after rapid induction and nasotracheal intubation after slow induction assisted by fiberoptic bronchoscope (FOB) in patients with obstructive sleep apnea syndrome (OSAS).Methods Forty ASA Ⅱ patients with OSAS and hypertension, aged 38-64 yr, weighing 82-123 kg, undergoing uvulopalatopharyngoplnsty, were randomly allocated into 2 groups (n = 20 each): group Ⅰ awake nasotracheal intubation through FOB after slow induction and group Ⅱ orotracheal intubation through laryngoscope and FOB after rapid induction. MAP and HR were recorded immediately after anesthesia induction and intubation. The intubation time was recorded, and rate of successful intubation, incidences of tschycardia, hypertension and myocardial ischemia during intubation, and satisfactory rate of otolaryngologists with airway management were calculated. Results The rate of successful intubation were significantly higher, MAP and HR after induction were significantly lower, incidences of tachycardia, hypertension and myocardial ischemia during intubation were significantly lower, and satisfactory rate of otolaryngologists was significantly higher in group Ⅱ than in group Ⅰ ( P < 0.05). Four patients in group Ⅰ had nasal bleeding after extubation. Conclusion Orotracheal intubation after rapid induction assisted by FOB provides less hemodynamic response to endotracheal intubation and higher success rate with less injury to the airway in patients with OSAS than nasotracheal intubation after slow induction assisted by FOB.

A comparative study on vascular blockade during hemihepatectomy for primary hepatic carcinoma / 中国普通外科杂志

Objective To compare among three different methods in performing hepatic vascular blockade during hemihepatectomy for primary hepatic carcinoma ( PHC). Methods Between 2000 and 2005, 83 PHC patients underwent the Pringle's maneuver (Group A) , 67 cases in combination Pringle's maneuver and inferior vena cava (IVC) clamping (Group B) , and 32 cases received anatomical blood flow blockade for the half liver for hemihepatectomy ( Group C). Results Operation time in group C was longer than that in group A and B(t =3. 27、2. 74,all P
