To determine mortality risk factors for critically ill postoperative patients. ⋯ Surgical patients in critical condition continue to account for a large number of admissions to and death in the ICU. The variables analyzed were sufficient to explain patient outcome, such that risk factors for mortality in surgical patients admitted to the ICU could be determined.

Comparative Study[Core and cutaneous thermal changes in the upper limb after anesthesia induction].
To describe and compare the core-cutaneous thermal and photoplethysmographic time-course effects after induction of general anesthesia with propofol, fentanyl and vecuronium. ⋯ Anesthetic induction with propofol, fentanyl and vecuronium produces cutaneous vasodilatation in the upper limb unequally: the greatest increase in skin temperature occurs at the fingertip, while forearm and upper arm temperatures increase less. We think that skin vasodilatation in peripheral distal areas may play an important role in redistributing core heat during anesthesia.

Clinical Trial[Sciatic nerve block. Description of a new posterior approach in the gluteal area].
To describe and assess the clinical usefulness of a new posterior approach for sciatic nerve block to the gluteal zone. ⋯ We describe a new approach for sciatic nerve block using only two points of osseous reference identified by palpation. The level of efficacy and safety is high.

Comparative Study Clinical Trial Controlled Clinical Trial[Comparison of patient-ventilator synchronization during pressure support ventilation versus amplified spontaneous pattern in postoperative patients].
Patient-ventilator desynchronization can develop during weaning from proportional-assist ventilation. Poor adaptation between ventilator assistance and the patient's ventilatory demand is termed asynchrony. ⋯ The incidence of asynchrony during assisted ventilation is very high with the PS mode and is substantially less with ASP. Asynchrony is difficult to detect clinically and is revealed only by advanced cycle-to-cycle monitoring.

Review[Failure of obstetric epidural analgesia and its causes].
The frequency of failure to establish and maintain an epidural block is low in Spain for surgery but higher in obstetrics. The reasons are many, but noteworthy factors are the prior experience of the anesthesiologist, the anatomical features of the patient and the type of material used. However, we lack clinical and anatomical studies of the epidural space that would allow us to come to definitive conclusions. ⋯ The anesthesiologist should avoid inserting too much of the epidural catheter and should assure firm support, checking it periodically and taking into account the patient's position. Finally the anesthetic dose should be adjusted to the progress of labor. The risk of incomplete analgesia and the possible need to insert a second epidural catheter must be discussed with the patient during preanesthetic evaluation.
