Clinical Trial[Analysis of induction with 5% isoflurane and 60% nitrous oxide in premedicated adults].
To analyze rapid inhalatory anesthetic induction in premedicated adults (fentanyl, droperidol, diazepam and atropine) with an inspired mixture of O2, N2O (60%) and 5% isoflurane as a means for accelerating induction time and reducing complications. ⋯ Rapid induction with 5% isoflurane is achieved within 1.5 min, with a 20% incidence of coughing and a 5% incidence of mask refusal. The high frequency of apnea (77%) is caused by the rapid elevation of alveolar isoflurane, which has an impact on the apneic threshold. Anesthetic induction with 5% isoflurane and 60% nitrous oxide in premedicated adults is accomplished with good maintenance of hemodynamic stability. However, tachycardia and arterial hypertension appear after laryngoscopy and tracheal intubation.

[Postoperative mental confusion in the elderly with hip fracture. Perioperative risk factors].
To determine the incidence of postoperative mental confusion and perioperative risk factors in elderly patients with femoral neck fractures. ⋯ A high incidence of postoperative mental confusion is associated to pre-surgical factors. We therefore suggest that greater preventive and therapeutic efforts be directed preferably to preparation before surgery, especially in patients at high risk.

Randomized Controlled Trial Comparative Study Clinical Trial[Influence of anesthetic technique in postoperative analgesia in thoracic surgery].
To compare the intensity of postoperative pain after thoracotomy with 2 anesthetic techniques: 1) thoracic epidural block with bupivacaine administered before surgery (combined anesthesia with isoflurane) and 2) conventional balanced anesthesia with isoflurane and endovenous fentanyl. ⋯ Analgesic efficacy after thoracotomy was similar for our 2 groups receiving either combined anesthesia (epidural bupivacaine at 0.5% and isoflurane) or balanced anesthesia with isoflurane and endovenous fentanyl.

Clinical Trial[Treatment with sympathetic intravenous block with reserpine in work-related reflex sympathetic dystrophy].
To assess the results obtained in treatment of sympathetic reflex dystrophy by sympathetic endovenous blockades with reserpine in working patients. We reviewed 170 diagnoses of sympathetic reflex dystrophy in 165 patients. One hundred seven were located in the foot, 13 were in the knee and 50 were in the hand. ⋯ Sympathetic reflex dystrophy leads to loss of 215 +/- 91 working days. In patients with Colles' fracture without sympathetic reflex dystrophy the loss is 96 +/- 31 days, although this period lengthens to 115 +/- 15 days if the two conditions are associated in stage I and to loss of 193 +/- 71 days if the association is in stage II. Results of treating sympathetic reflex dystrophy with sympathetic endovenous blocks with reserpine are satisfactory, particularly when diagnosis and treatment are early, clearly demonstrating the usefulness of this technique in workplace medicine.
