Active clinical trials for "Laryngismus"

Investigation of pupillometry as guide for extubation readiness in anesthetized children.

The aim of this study is to evaluate whether there is a significant relation between various arrhythmias during the surgeon's stretching the eye muscles and laryngospasm and emergence agitation in strabismus surgeries

To describe laryngeal and respiratory reflex responses after controlled laryngeal stimulation in pediatric patients anesthetized with sevoflurane and to compare the evoked responses at two levels of anesthesia. To determine whether laryngeal and respiratory reflex responses after controlled laryngeal stimulation are completely suppressed in subjects when anesthetized with a MACEI95 (EI = endotracheal intubation) sevoflurane Hypothesis: The incidence of apnea with laryngospasm evoked by laryngeal stimulation will be reduced by 20% (from 25% to 5%) when the end-tidal concentration of sevoflurane is increased from 2.5% (MAC50) to 4.7% (MACEI95)

In the literature, we found no randomized clinical trials addressing the using of IV lidocaine as prophylaxis for postoperative laryngospasm among adults. The aim of this study was to assess the effects of IV lidocaine on the incidence of postoperative laryngospasm of adults patients.

Tonsillectomy is one of the most common surgical performed procedures in children. Adenotonsillectomy surgery in pediatrics is commonly managed as an ambulatory surgery. This may be attributed to the use of the electro-dissection surgical technique that decreases the incidence of immediate postoperative hemorrhage. However, the use of the electro-cautery technique increases postoperative inflammation. Postoperative throat pain is a very important and significant problem because it can lead to decreased oral intake and dehydration with subsequent serious complications of dehydration.

To describe respiratory and laryngeal responses to laryngeal stimulation during propofol anesthesia in children. To determine whether the co-administration of lidocaine blunts these reflex responses. The outcome of primary interest is the reflex laryngospasm. Hypotheses: I: The severity of laryngospasm evoked by laryngeal stimulation is reduced 2 min. after iv. administration on 2mg/kg lidocaine in pediatric patients anesthetized with propofol (3mcg/ml). II:The incidence of laryngospasm elicited by controlled stimulation 10min. after iv. administration of lidocaine is equivalent to the response before the administration of lidocaine.

The purpose of this study was to determine the most suitable effect-site concentration of remifentanil for the LMA insertion during inhaled induction with 8% sevoflurane in adults.

The purpose of this study is to identify patient and provider-chosen factors that put patients at risk for the development of hypoxemia (oxygen saturation < 90% for 5 seconds) during endoscopy and to use this knowledge to develop a treatment protocol for specific causes of hypoxemia in adult esophagogastroduodenoscopy outpatients.

The purpose of this study is to determine whether exchange of the double lumen tube before emergence with a laryngeal mask airway (Proseal) or a tracheal tube will reduce cough at emergence.

The purpose of this study is to determine whether the use of laryngeal mask classic as method for securing the airway in the population of 2 years to 14 years is associated with risk of laryngospasm as compared with the use of endotracheal tube.
