Randomized Controlled Trial Clinical TrialPreanesthetic wrapping of legs for prevention of spinal induced hypotension.
Forty-four male patients undergoing herniorrhaphy under spinal anesthesia were allocated to 2 groups. Group I had 15 ml/kg of lactated ringer intravenously as prehydartion for prevention of spinal induced hypotension. Group 11 had the trendelenbourg position to 30 degrees for 2 minutes and the legs wrapped with elastic Esmarch bandage prior to spinal anesthesia without fluid prehydration. ⋯ The later was defined as a decrease in the systolic arterial pressure less than 75% of the baseline value. The incidence of hypotension was greater in the fluid prehydration group (4 of 22) as well as the mean dose of ephedrine required to treat hypotension (7 +/- 10 mg) than the group with wrapping of the legs (1 of 22 and 5 +/- 0 mg). It is concluded that trendelenbourg position and wrapping of the legs prior to the spinal block might prevent the sudden decrease in arterial blood pressure that occurs during spinal anesthesia.

Case ReportsIpsilateral bronchial intubation in a neonate for expansion of post-operative unilateral atelectasis--case report.
Ipsilateral bronchial intubation was used for reexpansion of unilateral pulmonary atelectasis in a newborn, who developed postoperative right atelectasis following extrapleural repair of tracheoesophageal fistula.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of laryngeal mask airway with endotracheal tube for airway control.
The study was designed to compare the effectiveness and ease of the insertion of the laryngeal mask airway (LMA) and the endotracheal tube (ETT) according to the presence of signs of difficult airway. Eight hundred seventy nine patients undergoing elective surgery were randomly allocated in the ETT group (n = 453) and the LMA group (n = 426). Airway assessment was performed using the original Mallampati classification and measuring the maximum range of the head and neck mobility. ⋯ Patients with suspected or observed difficulty in tracheal intubation proved to have easy insertion of LMA. Additionally, the ease of intubation was unrelated to potential failure of proper insertion of LMA. Although "difficult" patients in both studied groups have similar frequencies, the underlying anatomical characteristics were not similar.

Desflurane is a new halogenated ether inhalational general anesthetic with low solubility in blood and body tissues. The aim of this study was to assess its anesthetic efficacy in elective surgical procedures, to evaluate its effect on patients' vital signs during maintenance and recovery and to detect the possible side effects (if any) on patients' liver and kidney functions. The study was carried out on thirty adult (ASA I and II) patients scheduled for different surgical procedures. ⋯ There was no observable effect on both liver and kidney function given the small number of patients that were included in this study. In the post anesthetic period desflurane showed rapid recovery (3.81 +/- 4.076) and patients' recovery room stay was (17.22 +/- 1.079 min). No postoperative complications were detected.

Randomized Controlled Trial Clinical TrialReduction of propofol pain--fentanyl vs lidocaine.
To compare the local efficacy of lidocaine and fentanyl in reducing propofol injection pain (PIP), we conducted a prospective randomized double-blind study in 75 ASA I and II adult patients. When administered 20 seconds before propofol with a venous tourniquet, lidocaine but not fentanyl or placebo, reduced the incidence of moderate to severe pain on subsequent injection of propofol (P < 0.001). ⋯ Fifteen (60%) in the fentanyl group (n = 25) experienced moderate or severe degrees of pain, compared with 15 (60%) in the saline group (n = 25). We conclude that lidocaine, acting locally, reduce propofol injection pain while fentanyl does not.
