Our aim was to assess if peri-operative blood transfusion is an independent risk factor for mortality and morbidity in the elderly. We report the results of a cohort study of all patients aged 80 or more on the day of their emergency or elective cardiac surgery (n = 874), using routinely collected data from January 2003 to November 2007. The primary outcome was all-cause mortality in hospital. ⋯ Relative to 0-2 units, the odds ratio for > 2 units was 6.80 (95% CI 2.46-18.8), and for other additional blood products was 14.4 (95% CI 5.34-37.3), with a p value of < 0.001. Duration of stay in the ICU was significantly associated with the amount of blood products administered (median (IQR [range]) ICU stay 1 (1-2 [0-15]) day if transfused 0-2 units of red blood cells, 2 (1-6 [0-128]) days if transfused > 2 units of red blood cells and 3 (1-76 [0-114]) days if other clotting products were used; p value < 0.001). Hospital stay was also associated with the amount of red cells used (p < 0.001).

The LMA Supreme has been suggested for use in emergency situations by medical personnel with no experience in endotracheal intubation. We evaluated the LMA Supreme when inserted by non-anaesthetists, firstly in a manikin and then in patients. Fifty airway novices inserted a LMA Supreme in a manikin without any complications so we proceeded to the patient phase. ⋯ Results are consistent with previous studies of use of the LMA Supreme by airway experts. We conclude that the LMA supreme is suitable for use by airway novices. Further research is needed before it may be recommended for cardiopulmonary resuscitation and emergency airway use.
