Chronic pain is a challenge for modern medicine. New methods and drugs have been proposed to control pain. Intrathecal administration is a feasible and safe option, but still requires further investigations. This study aimed at reviewing available and well established drugs as well as new promising alternatives for the daily practice. ⋯ Several advances were achieved in controlling pain with intrathecal administration of the above-mentioned drugs. Certainly some will be used, thus enriching therapeutic armamentarium, and others will be temporarily or permanently abandoned. However, several clinical and experimental studies will still be needed for knew knowledge to be incorporated and safely used by professionals dealing with chronic pain.

[Efficacy of propofol and propofol plus dexamethasone in controlling postoperative nausea and vomiting of gynecologic laparoscopy.].
Gynecological laparoscopy is a procedure associated to a high incidence of postoperative nausea and vomiting (PONV). This study aimed at comparing the efficacy of propofol or propofol plus dexamethasone in preventing PONV in patients submitted to gynecological laparoscopy. ⋯ Propofol or propofol plus dexamethasone were efficient in preventing PONV in patients submitted to gynecological laparoscopy.

Respiratory complications are responsible for a major number of elderly deaths after surgical procedures. Aging entails an important decrease in respiratory system functional reserves, while an increasing number of elderly people are being submitted to increasingly complex procedures. This study is a review of the respiratory system during aging and of anesthesia-induced changes in the elderly, emphasizing preoperative evaluation of respiratory function, postoperative pulmonary complications and details of anesthetic management. ⋯ Aging brings about several respiratory system changes. Evidences have shown that, even in the absence of pulmonary disease, advanced age is a risk factor for postoperative pulmonary complications. It is necessary a thorough evaluation of preoperative respiratory function, adequate anesthetic management and specific postoperative care.

Although rare, spinal anesthesia-induced neurological complications may determine serious sequelae. This study aimed at presenting these complications in order to elucidate triggering factors and help in the diagnosis of such injuries. ⋯ The understanding of triggering factors of spinal anesthesia-induced neurological complications may prevent injuries and help early diagnosis and treatment, therefore changing patients prognosis.

[Remifentanil associated to propofol or sevoflurane for videolaparoscopic cholecystectomy: a comparative study.].
Different intravenous, inhalational or combined anesthetic techniques have been used for videolaparoscopic cholecystectomy. This study aimed at comparing hemodynamic parameters, anesthetic recovery and side-effects of remifentanil associated to propofol or sevoflurane. ⋯ Both techniques decrease blood pressure and heart rate. Anesthetic recovery was similar for both techniques. A higher incidence of vomiting was observed when remifentanil was associated to sevoflurane.
