Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of cocaine, lidocaine with epinephrine, and oxymetazoline for prevention of epistaxis on nasotracheal intubation.
The alpha-adrenergic agonist oxymetazoline was compared to cocaine and to lidocaine with epinephrine with respect to prevention of epistaxis on nasotracheal intubation. The nares of three groups of 14 patients each were topically pretreated with 4% lidocaine with 1:100,000 epinephrine (group 1), 10% cocaine (group 2), or 0.05% oxymetazoline (group 3) prior to nasotracheal intubation. After intubation, epistaxis was estimated on a scale of 0 to 3, with 0 indicating no bleeding, 1 representing blood on the nasotracheal tube only, 2 indicating blood pooling in the pharynx, and 3 representing blood in the pharynx sufficient to impede intubation. ⋯ In addition, heart rate (HR) and blood pressure (BP) were examined prior to administration of the medications; at 5 minutes, 10 minutes, and 15 minutes after administration of the medications; and after intubation. No significant differences were noted (p greater than 0.05) between the medications except for a slightly higher systolic BP for cocaine than for lidocaine with epinephrine at 15 minutes. The results of this double-blind, randomized trial demonstrate that the alpha-adrenergic agonist oxymetazoline is as effective as cocaine, and more effective than lidocaine with epinephrine, for the prevention of epistaxis associated with nasotracheal intubation.

Randomized Controlled Trial Comparative Study Clinical TrialNosocomial maxillary sinusitis during mechanical ventilation: a prospective comparison of orotracheal versus the nasotracheal route for intubation.
Nosocomial maxillary sinusitis during mechanical ventilation may cause life-threatening complications in ICU patients. The aim of this prospective study was to compare the incidence of maxillary sinusitis according to the route of intubation. 111 consecutive adult patients (mean age: 53, mean SAPS: 12) were randomly assigned to receive either orotracheal (n = 53) or nasotracheal (n = 58) intubation. All had a nasogastric feeding tube. ⋯ This procedure proved successful in 12 out of 17 cases but secondary drainage was performed in 5 cases (1 failure). Incidents related to the route for long-term intubation were significantly (p less than 0.001) more frequent in the orotracheal group (8/53 vs 2/58), however no patient died because of them. In this study, long-term orotracheal intubation reduced significantly the incidence of maxillary sinusitis in comparison with nasotracheal intubation.

Case Reports
Acute pulmonary edema, an unusual complication following arthroscopy: a report of three cases.
Acute pulmonary edema in the young athlete is a rare complication following arthroscopic surgery. It is not related to fluid absorption during arthroscopy, but rather to a brief period of upper airway obstruction. ⋯ Young athletes may be at increased risk for laryngospasm-induced pulmonary edema because they have the ability to generate large negative intrathoracic pressures. This condition must be recognized promptly to minimize morbidity and mortality.

Presented here is a case of unilateral pulmonary edema following acute subglottic edema after removal of an endotracheal tube. A 3-year-old boy, diagnosed as having nondiphtheric croup and pectus excavatum deformity, was scheduled for repair of a cleft lip. ⋯ After reintubation of the trachea, frothy pink fluid was discharged from the tube, and chest roentgenogram showed a right-sided alveolar infiltrate. Many factors may cause unilateral pulmonary edema, but it is suggested that acute subglottic edema and unilateral bronchial fragility strongly affected this episode.

Anaesthetists are responsible for the management of the airway in patients with unstable cervical spines. Unfortunately, the anaesthetic literature does not contain a recent, critical analysis of the current medical literature to aid anaesthetists attending such patients. This review is intended to serve such a purpose. ⋯ Relevant findings included the high prevalence of cervical spinal instability in such disorders such as Trisomy 21 and rheumatoid arthritis and the relatively low incidence after trauma. There are deficiencies in the minimalist approaches to assessing the cervical spine, such as a simple cross table lateral radiograph after trauma, as they are neither sensitive nor specific. Finally, recognizing the potential for instability and intubating with care, while avoiding spinal movement, appears to be more important than any particular mode of intubation in preserving neurological function.
