[Precautions to be taken from the anesthesiologic point of view during venous surgery in the obese].
Paraules clau
Resum
Certain precautions must be taken in venous surgery on the obese patient, as obesity is always accompanied by a number of particular pathological manifestations: haemodynamic disorders (breakdown of the functioning of the left ventricle and hypovolemia), or respiratory disorders (reduction of residual functional capacity and of expiratory volume of the reserve). The posture of the patient on the operating table can also exacerbate the operative risk. Prior to the operation, respiratory functional exploration and gymnastics therefore play an important role. The anaesthetic has to take account of certain considerations. After the operation, the main risk is of respiratory deficiency.
