Comparative StudySevere neck burns and laryngeal mask airway for frequent general anesthetics.
Securing the airways in a patient suffering severe neck burns or its sequalae may present a challenge to the most experienced anesthesiologist. We investigate the utility of the Laryngeal Mask Airway (LMA) in this situation. We report on success, failure of complications of LMA insertion at the induction of general anesthesia in 23 patients of a Major Burns Unit and compare our results to our records of patients intubated endotracheally in the Unit. 14 out of 15 patients with neck burns had a LMA inserted with no difficulty or complications, while difficult endotracheal intubations in patients with neck burns were more frequent with statistical significance compared to patients with intact necks. LMA insertion seems to ignore the difficulties met with endotracheal intubation in this context.

Modified Laryngeal Mask Airway--a useful aid to fiberoptic intubation.
Modified Laryngeal Mask (MLMA) aided fiberoptic intubation (FOI) using larger than 6 mm ID endotracheal tube was studied in 25 adult patients and compared to unaided FOI in another 25 patients. MLMA aided FOI was successful in 96% cases compared to 56% in the unaided group. ⋯ However, maximum fluctuations in the heart rate and mean arterial pressure in the immediate post-intubation period were statistically insignificant between the groups. We conclude that MLMA not only adds to success rate of FOI but also significantly reduce the FOI time in adult patients.

Randomized Controlled Trial Clinical TrialDepression of excitatory effects of propofol induction by fentanyl.
Propofol is an intravenous anesthetic drug commonly used in outpatient anesthesia for its rapid and smooth onset of action, short recovery period and its minimal perioperative side effects. However, propofol like other intravenous anesthetic drugs can produce excitatory signs during induction without signs of epilepsy on EEG. We studied 64 patients scheduled for various outpatient procedures. ⋯ Fentanyl 1.5 ug. Kg-1 used in outpatient anesthesia with propofol 2 mg. Kg-1 provides cardio-vascular stability, deepens the anesthesia level, decrease the awareness and decrease the excitatory effects or propofol.

Clinical TrialModified interface between pediatric ventilator and Ayre's T-piece for use in neonates.
The lowest tidal volume delivered by most of the pediatric anesthesia ventilators could be large for neonates, and may generate unacceptably high peak airway pressures. The effective tidal volume can however be reduced by connection of a small rubber bag between the ventilator and the expiratory limb of the Ayre's T-piece circuit to divide the delivered gas mixture between the added bag and the neonate's lungs. The delivered tidal volume by the ventilator can then be manipulated to achieve the desired peak inspiratory pressure; 18-20 cm H2O in neonates with normal lung compliance. The modification was found to be simple, safe and convenient.

Comparative StudyIs antacid treatment necessary in obstetric anesthesia?
All the obstetric units in Jeddah were surveyed regarding the use of antacid prophylaxis and the methods of anesthesia used for emergency and elective cesarian section. The results were compared with the Western practice where marked variation was found but this apparently did not influence mortality from acid aspiration.
