Many studies state the need to administer supplementary oxygen to elderly patients in the postoperative period (POP) after regional anesthesia as a prophylaxis of hipoxemia. Bearing in mind the above mentioned, we decided to confirm the behaviour of oxygen saturation (O2S) in the POP of these aged patients that were assisted with this technique. Having cosulted the Scientifc Council, we proceed to a random selection of 50 ASA I-II-III patients (F = 30, K = 20) that underwent an operation of inferior hemiabdomen and lower limbs. Demographic variables, personal pathologic histories (PPH) and 02S were obtained before the operation. Subarachnoid (SA) or peridural (PE) anesthesia was administered. 6 measurements of O2S were made (every 10 min. during l hour) on leaving the operating room.The results were statistically processed (comparison of means). Average age was 76 ± 6 years, PE 20 , SA 30, mean Hb 10.5 g/L, preoperative O2S 94 % ± 1.5. The following measurements were made during the POP: lst, 95 % ± 1.8; 2nd, 94 % ± l.3; 3rd, 93 % ± 2.1; 4th, 95 % ± 1.9; 5th, 94 % ± l.5; 6th, 93 % ± l.7
