Filter by:The investigators evaluated the usefulness of the Glidescope(GVL) compared with direct laryngoscopy in patients whose airway management are anticipated difficult (C&L grade ≥3) by comparing the laryngoscopic view. Also, the investigators compared the effectiveness of smaller-size blade of GVL (GVLs) with standard blade of GVL selected by patient's weight (GVLw) in the same patients.
The purpose of this study is to compare the sedation effect of dexmedetomidine and target controlled remifentanil for awake nasotracheal fibreoptic intubation in patients undergoing oral maxillofacial surgery.
The investigators hypothesized that increasing the cardiac output by use of atropine in children might result in a reduction of the intubation time needed to facilitate tracheal intubation.
Nasogastric tube placement involves insertion of a flexible tube through the nose into the stomach. Placement of the tube can irritate the nose and palate and trigger gagging, causing discomfort, even if topical or local anesthetics are used. This study aims to determine if administration of an ultra-short acting sedative agent (midazolam) into a vein before the procedure, in addition to topical local anesthetic, will decrease the level of discomfort.
The purpose of this study is to determine the safety and efficacy of the C-MAC (Karl Storz Endoscopy, Inc., Tuttlingen, Germany) video intubation system guided intubation techniques. We hypothesize that the C-MAC video laryngoscope is safe and efficacious in terms of successful endotracheal intubation. The C-MAC may be a safe and suitable alternative device for routine and difficult laryngoscopy and tracheal intubation. This is the first study to investigate the performance of C-MAC in clinical practice.
Nasogastric tube insertion is one of the most common invasive procedures performed in children's hospitals, and has long been recognised as one of the most traumatic and painful. As a once off procedure, a nasogastric tube insertion is extremely distressing but the repeated procedures that many children endure as a necessary part of treatment for a chronic disease can be so traumatic that psychological damage may occur. There have been a limited number of studies carried out which have looked at methods to reduce the pain and trauma associated with this procedure, but most of these have been carried out in the adult population. The investigators propose to carry out a research project in a paediatric setting to definitively investigate the use of local anaesthetic spray, in combination with local anaesthetic gel, to numb the nasal passages and the back of the throat, with the aim of reducing or removing the unpleasant sensation of the nasogastric tube placement. If the study shows a benefit from the use of local anaesthetics, it would be an inexpensive and easily incorporated intervention that could be inserted into the routine procedure for nasogastric tube insertion.
Difficult airways is still a challenging issue for the anesthesiologists in spite of the development of various techniques.Shikani optical stylet(SOS), combining the features of fiberoptic bronchoscope and a lightwand, has been used for orotracheal intubation with difficult airways. As compared with fiberoptic bronchoscope, SOS is less expensive, easy to learn and more durable. However, it remains elusive whether SOS can be used in the nasotracheal intubation in the oral and maxillofacial surgery, which normally requires the nasotracheal intubation. The present study evaluates the safety and efficacy of SOS for nasotracheal intubation in the oral and maxillofacial surgery requiring nasotracheal intubation.
Mechanical ventilation commonly is associated with patient agitation requiring sedation to alleviate discomfort and reduce excessive central respiratory drive. Upon recovery from acute respiratory failure, sedation is reduced to facilitate the withdrawal of ventilatory support. In some patients, abrupt reduction in sedation provokes severe agitation that causes catecholamine release resulting in severe hypertension, tachycardia and tachypnea. This requires increased sedation to bring hemodynamic and respiratory function under control. Dexmedetomidine is an alpha-2 receptor agonist with both sedative and analgesic properties that allows for the reduction in the anesthetic and analgesic requirements in the perioperative setting. In addition to its sedative effects, alpha-2 receptor stimulation in the central nervous system inhibits sympathetic activity and reduces plasma epinephrine and norepinephrine levels, thereby lowering both arterial blood pressure and heart rate. Because alpha-2 receptor stimulation does not cause respiratory depression, dexmedetomidine may facilitate the transition to unassisted breathing in profoundly agitated patients. The investigators will prospectively evaluate dexmedetomidine in 30 patients who could not be extubated because of agitation with hemodynamic instability and tachypnea. The purpose of this study is to test if a larger prospective randomized controlled pilot study can show that dexmedetomidine facilitates weaning and extubation in patients who have failed previous attempts because of agitation and hyperdynamic cardiopulmonary response.
The expected benefit is a reduction of the morbidity of patients admitted in the intensive care unit having received ketamine for intubation.
