[More than 3 hours and less than 3 years: Safety of anaesthetic procedures in infants less than 3 years old subected to surgery for more the 3 hours].

An FDA alert in December 2016 on the safety of general anesthesia and sedations in patients less than 3 years of age and pregnant women has raised doubts in relation to the attitude that professionals implicated in these procedures should adopt in relation to these specific group of patients. Confronted with this situation, the following medical scientific societies: Sociedad Española de Anestesia y Reanimación (SEDAR), Sociedad Española de Cirugía Pediátrica (SECP), Sociedad Española de Cuidados Intensivos Pediátricos (SECIP) y Sociedad Española de Neonatología (SENeo), have established a working group to analyze and clarify the safety of these techniques. In the present article we conclude that at present both general anesthesia and profound sedation are considered safe procedures because there is no evidence of the opposite in studies with human beings.

Effect-site concentration of propofol required for LMA-Supreme™ insertion with and without remifentanil: a randomized controlled trial.

Background: A new supraglottic device, the LMA-Supreme™, has recently become available for clinical use. Information on anaesthetic and co-adjuvant requirements for insertion of the LMA-Supreme™ is limited. The present study aimed to evaluate the optimal effect-site concentration of propofol in 50 % (EC50) of adults necessary for successful insertion of the LMA-Supreme™ and to examine remifentanil's effect on propofol requirements.

Preoperative smoking cessation counseling activities of anesthesiologists: a cross-sectional study.

Background: Smokers undergoing surgery are at a higher risk of complications than non-smokers. Preoperative evaluation by an anesthesiologist could provide an excellent opportunity to promote smoking cessation. Previous surveys of anesthesiologists have found that self-reported smoking cessation counseling rates have room for improvement, but no study has surveyed patients to obtain more accurate estimates.

The Size 1 ProSeal™ laryngeal mask airway in infants: a randomized, noncrossover study with the Classic™ laryngeal mask airway.

Background: In recent years, numerous scientific publications have endorsed the superiority of the ProSeal™ laryngeal mask airway (PLMA) over the Classic™ laryngeal mask airway (cLMA) in adults, children, and infants. The PLMA forms a better seal for both the respiratory and gastrointestinal tracts, provides easier access to the gastrointestinal tract, and exerts lower mucosal pressures for a given seal pressure. This study aims to determine whether this superiority can also be observed for the size 1 PLMA used in anesthetized neonates and infants with positive pressure ventilation.

Anesthesia for pediatric gastroscopy: a study comparing the ProSeal laryngeal mask airway with nasal cannulae.

Background: We tested the hypothesis that pediatric gastroscopy is more successful using the ProSeal laryngeal mask airway with the drain tube as a conduit to the stomach (ProSeal LMA group) than using nasal cannulae with conventional oral access to the stomach (NC group).

Methods: Sixty children were consecutively and randomly allocated into each group. Patients breathed spontaneously and were given sevoflurane/air/oxygen mixture with propofol 1 mg.
