Difficulty of tracheal intubation is caused by many reasons and among them tracheal rupture is an infrequent factor. Tracheal rupture leads to higher mortality and poorer prognosis especial for closed tracheal rupture which is hard to early diagnose and is generally fatal. We described a case of a 34-year-old narcose man after a car accident that accepted twice unsuccessful tracheal intubation ...

BACKGROUND It was well-known that smoking affects the cardiovascular system, and remifentanil can suppress the sympathetic stimulations induced by tracheal intubation. The purpose of this study was to investigate whether there was any difference in the hemodynamic changes induced by tracheal intubation with using remifentanil between smokers and nonsmokers. METHODS EIGHTY PATIENTS WERE ENROLL...

BACKGROUND Aims of this study were to assess the maximum displacement of tracheal tube tip during head-neck movement in children, and to evaluate the appropriateness of the intubation depth marks on the Microcuff Paediatric Endotracheal Tube regarding the risk of inadvertent extubation and endobronchial intubation. METHODS We studied children, aged from birth to adolescence, undergoing cardia...

BACKGROUND Tracheal intubation in the prone position has previously been reported only as a necessity in a very few emergency situations. It emerged at our clinic as a routine after invention of a test aimed at pinpointing a painful motion segment in patients with chronic low back pain who were candidates for lumbar fusion operation. MATERIAL AND METHODS During a 6-year period 247 consecutive...

We have investigated the haemodynamic changes in response to induction of anaesthesia and tracheal intubation in patients who received either thiopentone 5 mg kg-1 or propofol 3 mg kg-1 followed by atracurium 0.5 mg kg-1 and fentanyl 1.5 micrograms kg-1. Anaesthesia was maintained with 0.6% enflurane and 50% nitrous oxide in oxygen with assisted ventilation. Cardiac output and heart rate (HR) w...

BACKGROUND Problems with tracheal intubation are a major cause of anaesthesia-related morbidity and mortality. Difficulty with tracheal intubation is primarily a consequence of failure to see the vocal cords with conventional direct laryngoscopy. We report our experience with use of the SensaScope for tracheal intubation in routine clinical practice. METHODS The SensaScope is a hybrid steerab...

BACKGROUND Desflurane at more than 1 minimum alveolar concentration (MAC) has been shown to prolong the QT interval, but it is unclear whether this is the case at lower concentrations. The aim of this study was to determine whether desflurane concentrations of <1 MAC affect tracheal intubation-induced prolongation of the QT interval. METHODS Forty-four subjects received either inspired desflu...

BACKGROUND Patients with obstructive sleep apnoea (OSA) can often present difficulties in intubation. This study aimed to compare the efficacy of the Pentax AirWay Scope (AWS) with that of the Macintosh laryngoscope for tracheal intubation in patients with OSA. METHODS Forty-six patients undergoing uvulopalatopharyngoplasty were randomly allocated to tracheal intubation with either the Macint...

Background: The LMA CTrachTM system is a new device for airway management and endotracheal intubation under direct vision in both anticipated and unexpected difficult intubation situations. This randomized controlled study was undertaken to compare the hemodynamic effects, ease of intubation, time taken for intubation, upper airway morbidity following tracheal intubation through LMA CTrachTM wi...

BACKGROUND A common complaint after endotracheal tube use is sore throat, which may be due to abrasion, ischemia-reperfusion injury, or an inflammatory reaction. Few studies have evaluated localized tracheal inflammation as part of the response to intubation. METHODS Inflammation of the trachea due to intubation was assessed in a swine model by following indicators of inflammation over time i...
