Tubeless anaesthesia for microlaryngeal surgery.

摘要: An anaesthetic technique for laryngeal microsurgery is described and evaluated using intravenous propofol infusion topical lignocaine with the patient breathing spontaneously without an endotracheal tube. Eighty adult patients divided into two groups according to their ASA status (Group A; 58 I II; Group B; 22 III IV) were analysed. Operating conditions good in all but one case. Good anaesthesia was achieved about 70% of patients. The requirement less B. Blood pressures decreased significantly following induction (P than 0.001) returned towards preoperative values after ten minutes A whereas recovery slower Apnoea occurred on 40% overall. PaCO2 showed a similar small increase both groups. Oxygenation adequate. results show that as this simple tubeless satisfactory. As considered potentially hazardous those upper airway obstruction, such not included study.
