[Anesthesia in obese patients].

Anesthesiological aids were analyzed in 70 obese patients undergone a total of 88 surgical interventions (in 1992 to 2002). This category of patients presented difficulties with tracheal intubation and gas exchange management at all stages of anesthesia and medication, which is associated with high chest rigidity, large distribution volume due to excess fatty tissue and serious comorbidity. The authors propose basic ways of solving the problems occurring with the use of fibrooptic equipment for tracheal intubation and suggest that short-acting agents with extraorgan elimination for induction and maintenance of anesthesia and special methods of artificial pulmonary ventilation (traditional volume-cyclic and jetwise high-frequency pulmonary ventilation) should be used to maintain effective gas exchange.

[Total intravenous anesthesia based on propofol infusion with target concentration: a new procedural solution].

Total intravenous propofol anesthesia with target control (TCI) infusion was used in 61 surgical patients (43 women, 18 men, ASAI-II). Propofol concentration in the central compartment at awakening was in high correlation with the effective concentration (Ce) at the moment of falling asleep (r = 0.64).
