Rigid bronchoscopy under general anesthesia enables performing diagnostic and/or therapeutic procedures in the tracheobronchial tree. This technique is characterized by specific technical problems, insofar as the anesthesiologist and the operators share the same space, namely the airway. Several potential complications (hemorrhage inside the airway, threat to ventilation ...) may arise. ⋯ General anesthesia is usually total intravenous anesthesia, using short acting agents. Ventilation can be spontaneous, but more often insured using high-frequency jet ventilation. The hospital infrastructure and staff must have the expertise to perform this particular procedure, in order to limit the complication rate.

Randomized Controlled Trial Comparative StudyA comparison of the effects of lidocaine or magnesium sulfate on hemodynamic response and QT dispersion related with intubation in patients with hypertension.
The aim of this study was to investigate the effect of magnesium administered before induction on the hemodynamic response and QT dispersion (QTd) related with intubation in hypertensive patients and to compare it with lidocaine. ⋯ QTd is not increased during tracheal intubation in hypertensive patients so there is no need for magnesium sulfate for these patients. But as QTd has been shown to increase during tracheal intubation for coronary artery disease patients, magnesium sulfate might be useful for those patients although future studies are required to confirm this statement.

Preeclampsia was formerly defined as a multisystemic disorder characterized by new onset of hypertension (i.e. systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg) and proteinuria (> 300 mg/24 h) arising after 20 weeks of gestation in a previously normotensive woman. Recently, the American College of Obstetricians and Gynecologists has stated that proteinuria is no longer required for the diagnosis of preeclampsia. This complication of pregnancy remains a leading cause of maternal morbidity and mortality. ⋯ Airway edema and tracheal intubation-induced elevation in blood pressure are important issues of general anesthesia in those patients. The major adverse outcomes associated with preeclampsia are related to maternal central nervous system hemorrhage, hepatic rupture, and renal failure. Preeclampsia is also a risk factor for developing cardiovascular disease later in life, and therefore mandates long-term follow-up.

Review Case ReportsApproach to one lung ventilation during the surgical resection of an intrathoracic ganglioneuroblastoma in a three-year-old child: a case report and review of the literature.
One lung ventilation (OLV) in children is a challenge and requires creative solutions. A case of OLV with bronchial placement of a fiberscope inspection-guided vascular embolectomy catheter in a three-year-old girl, scheduled for the resection of an intrathoracic tumor through thoracotomy is described. ⋯ Knowing all existing strategies in that domain is important to provide optimal perioperative care. In this paper, several methods of OLV in children will be discussed, such as selective endobronchial intubation, types of bronchial blockers, Univent tube, pediatric double lumen tubes, as well as the Marraro double lumen tube.

Randomized Controlled Trial Comparative StudyGabapentin versus naproxen in the management of failed back surgery syndrome; a randomized controlled trial.
Gabapentin is an analogue of the gamma amino butyric acid (GABA), which regulates the conductance of calcium channels. In this study, we compared the efficacy of gabapentin the one of naproxen in the treatment of failed laminectomy syndrome. In this controlled trial, patients who had had elective lumbar discectomy or spinal fusion surgery more than one year ago, and complaining about leg and back pain in spite of different medical therapy were randomly assigned to receive naproxen (control group) or gabapentin. ⋯ At 1800 mg, the reduction in VAS was 39.2%. Naproxen-treated patients had a 7.7% pain reduction at 6th week, when using the maximum daily dose of 1500 mg (P < 0.04), but the pain increased thereafter. We conclude that Gabapentin, at a maximum daily dose of 1800 mg, is significantly more efficient than naproxen at treating persistent pain after spinal surgeries.
