A simple technique for contralateral left bronchial intubation in children undergoing right thoracotomy or thoracoscopy The
report describes a simple technique for blind contralateral left bronchial
intubation in young children undergoing right thoracotomy or right video-assisted
thoracoscopy. Following tracheal intubation, the tube was rotated 90 degrees
counter-clockwise, and the neck of the child was tilted to the right. Thus,
the curve of the tube was concave to the left, causing the tube to slide
along the left wall of the trachea towards the left main stem bronchus.

Succinylcholine resistance in a patient with juvenile hyaline fibromatosis Succinylcholine
resistance is a rare phenomenon which may occur in patients with elevated
plasma cholinesterse, or in myasthenic patients. However, the present report
describes unusual resistance to succinylcholine in a patient with juvenile
hyaline fibromatosis (JHF), who had normal cholinesterase values, as well
as normal neurologic and neurommuscular functions. A. Baraka. (Supported

Correlation of the end-tidal PCO2 (ETCO2) during laparoscopic surgery with the pH of the gastric juiceInfluence of the H2-blocker nizatidine During laparoscopy, the pH of the gastric juice is significantly decreased. The decrease in gastric pH is inversely related to the increase of ETCO2. The pre-operative administration of the selective H2-blocker nizatidine can prevent the increase of gastric acidity, and can even result in a paradoxical increase of gastric pH. A. Baraka, S.

administration of lidocaine 1.5 mg/kg prior to rocuronium-propofol sequence
minimizes the burning pain on injection, probably by a local anesthetic
action on the sensitive vein wall. Lidocaine may also act centrally to
deepen the level of anesthesia, and improve the conditions of tracheal
intubation. A. Baraka, S. Taha and S. Haroun-Bizri. (Supported

The self-inflating bulb (SIB) versus end-tidal capnography for confirming tracheal intubation in the parturient undergoing cesarean section The
self-inflating bulb (SIB) was associated with a high incidence of false
negatives in confirming tracheal intubation in the parturient undergoing
cesarean section. The false negatives can be attributed to decreased functional
residual capacity by the gravid uterus, which is further decreased by the
SIB-induced subatmospheric pressure. This can result in airway closure,
with a consequent delayed reinflation of the SIB. In contrast, capnography
was positive in all parturients, whether the SIB reinflated rapidly, slowly,
or even did not reinflate at all. The report shows that capnography, and
not the SIB, can dependently confirm tracheal intubation in the pregnant
woman at term. A. Baraka, S. Siddik, M. Sfeir, R. Salem* and N.
