Randomized Controlled Trial Comparative Study[Improved detection of the pulse oximeter signal with a digital nerve block in patients in poor health status].
To demonstrate the efficacy of a digital nerve block for improving pulse oximetry in conditions of low tissue perfusion. ⋯ A digital nerve block can be used to prevent pulse oximetry failures in conditions of low peripheral perfusion.

Randomized Controlled Trial Comparative Study[Efficacy of a continuous interscalene block vs intra-articular analgesia for postoperative pain in arthroscopic acromioplasty].
To compare the utility of intra-articular analgesia (IA) to that of a continuous interscalene block (CIB) by evaluating the quality of postoperative analgesia, a satisfaction index, and the incidence of complications. ⋯ Postoperative pain in the first 12 hours after shoulder surgery can be adequately managed with either IA or CIB. CIB is more effective than IA between 12 and 48 hours after surgery.

Review[Atelectasis in general anesthesia and alveolar recruitment strategies].
Atelectasis occurs in most patients during general anesthesia and is the main cause of hypoxemia. The objective of this review is to examine the causes and diagnosis of atelectasis and the different strategies for reducing or preventing this complication and improving oxygenation. Pulmonary atelectasis is mainly caused by 3 factors: compression, gas absorption, and lack of surfactant. ⋯ These include using positive end-expiratory pressure or a high tidal volume-thus providing a higher airway pressure (vital capacity maneuver)-or both in combination. Alveolar recruitment strategies have been tried in bariatric surgery, single-lung ventilation, laparoscopy, and adult respiratory distress syndrome. Their application has reduced or prevented atelectasis, thereby reducing postoperative pulmonary complications.
