The incidence of myocardial ischaemia during tracheal intubation and extubation was compared using ambulatory ECG monitoring in 60 patients undergoing a variety of different surgical operations. Seven patients had myocardial ischaemia after tracheal intubation and seven patients during tracheal extubation. The patients who developed myocardial ischaemia during tracheal extubation had significan...

OBJECTIVE A fast-track recovery in cardiac surgery yields many benefits, and early tracheal extubation is important as the first step. The purpose of this study is to evaluate the status of early tracheal extubation after on-pump coronary artery bypass grafting (CABG) and to find key factors for successful early tracheal extubation. METHODS From September 1996 to February 2005, isolated on-pu...

We studied prospectively the effects of the technique of tracheal extubation on arterial haemoglobin oxygen saturation (SpO2) in 120 ASA I-III children, mean age 5.3 (range 0.25-16.9) yr. At completion of surgery, tracheal extubation was performed when spontaneous ventilation had resumed, children were fully awake and SpO2 was 99-100%. Children were allocated randomly to receive a single lung i...

introduction: response to tracheal tube during emergence of general anesthesia is a main concern. we aimed to compare the effect of remifentanil and lidocaine on response to tracheal tube during emergence of general anesthesia. materials and methods: in this randomized clinical trial, we enrolled 80 consecutive patients with american society of anesthesiology (asa) physical status i–ii, who und...

We conducted a prospective survey on the incidence of respiratory complications associated with tracheal intubation and extubation in 1005 patients who underwent elective general anaesthesia over a 4-month period. During induction of anaesthesia, respiratory complications occurred in 46 patients (4.6%; 95% confidence limits (CL): 3.3, 5.9%). The common complications were coughing (1.5%) and dif...

Tracheal extubation in both the critical care and anesthesia setting is not only an important milestone for patient recovery, but also a procedure that carries a considerable risk of complication or failure. Mechanical ventilation is associated with significant complications that are time-dependent in nature, with a longer duration of intubation resulting in a higher incidence of complications,...

STUDY OBJECTIVE To determine the usefulness of routinely inserting a hollow airway exchange catheter (jet stylet) prior to tracheal extubation of adult patients with risk factors for difficult tracheal intubation. DESIGN Prospective, 1-year study of 40 consecutive patients undergoing mechanical ventilation who had one or more risk factors for difficult tracheal reintubation. SETTING Surgica...

We have compared changes in vocal function produced after insertion of a laryngeal mask airway (LMA) with those produced by tracheal intubation in 20 patients. Using acoustic waveform analysis, we computed amplitude variability (AV), pitch variability (PV), harmonics-to-noise ratio (HNR) and additive noise level (ANL) before anaesthesia and at 1, 4, and 24 h after tracheal extubation. There wer...

conclusions both remifentanil and magnesium had favorable outcomes in preventing hr and map elevation after tracheal extubation. however, remifentanil was associated with more rapid regaining of consciousness and reversal of muscular relaxation. results the hr was significantly lower, immediately after extubation and 3, 5, and 10 minutes after extubation, in both magnesium and remifentanil grou...
