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.
