Laryngeal mask airway insertion by classic and thumb insertion technique: a comparison.

We evaluated the efficacy of an alternative technique, for insertion of the silicone laryngeal mask airway (LMA) Classic™ in 40 American Society of Anesthesiologists grade ASA I and II patients scheduled for elective surgery. In group I (Index Finger group), the LMA was inserted by the classic index finger technique and, in group T (Thumb Insertion group), the thumb insertion technique was used. Ease of insertion, fiberoptic laryngoscopic position, cuff pressures and laryngopharyngeal morbidity were assessed in both study groups.

Genetic affinity of two south Indian ethnic groups with other populations.

Humans appear to have spread to several parts of the Indian subcontinent by the middle Paleolithic period. It also provided a major passage for the distribution of modern humans. For the first time generic human leucocyte antigen (HLA) class II (DRB1) genotyping was performed using polymerase chain reaction-sequence-specific primer (PCR-SSP) (low-resolution) technique in two endogamous groups (Hindu-Brahmins and Sunni-Muslims) from the southern state of Andhra Pradesh in order to decipher the genetic affinity between them and with other populations.
