Anaesthesia for ambulatory surgery implies a strict selection of patients. Screening tests are non specific, compared to these ordered for in-patients. ⋯ The detection of an asymptomatic anomaly by routine testing is extremely infrequent and does not lead to changes in the operating schedule or in the outcome of anaesthesia. Clinical examination and patient history are the only predictive elements, so systematic complementary tests should be abandoned and replaced by judicious selective prescription.

Randomized Controlled Trial Comparative Study Clinical Trial[Preventive treatment of hemodynamic disorders during conventional spinal anesthesia].
The prevention of blood pressure fall during a conventional spinal anaesthesia effected with 20 mg (4 ml) of isobaric 0.5 p. 100 bupivacaine relies on the use of vascular filling and/or a vasoconstrictor. A randomized prospective study was performed to evaluate the comparative efficacy of these two treatments. 148 patients were included and divided into three groups. Group I (n = 50): 2.5 mg IV bolus of etilefrine followed by continuous infusion (0.35 mg.kg-1.h-1). ⋯ Haemodynamic changes were fewer and less important in the etilefrine group compared with the saline infusion group. No failure and a better tolerance in the vasoconstrictor group were also to be noticed. These clinical data suggest that etilefrine could meet satisfactorily the therapeutic requirements.

Comparative Study[A comparison of 3.5% dextran 40 and 4% albumin used as volume expansion solutions following heart surgery. Effects on the hemodynamic parameters and the oncotic colloidal pressure].
Dextran 40 (3.5%), a synthetic colloid solution used as a volaemic expander was compared to albumin 4% in 30 patients (15 in each group) during the first twenty hours after cardiac surgery. The patients were administered 500-600 ml.m-2 either dextran 40 or albumin at a rate of 10-12 ml.kg-1 x h-1 between 2nd and 4th postoperative hour. In the two groups, heart rate and mean arterial pressure did not change significantly but left and right filling pressures and cardiac index increased similarly. ⋯ Diuresis was not different in the two groups. No side effect was observed. Dextran 40 was efficient and could be used as a volaemic expander after cardiac surgery.

The use of regional anaesthesia in day care practice is discussed. Five criteria of discharge are described: the four "A"s: awake, ambulation, alimentation, analgesia plus micturition. Complementary sedation with the regional block, if needed, should be midazolam and fentanyl. ⋯ However, urinary retention and orthostatic hypotension can occur. Furthermore the risk of headache is not a contraindication to an ambulatory practice if some guidelines are observed. In addition, penile blocks and caudal blocks are widely used in pediatrics.
