The possibility to achieve unilateral spinal anesthesia with 0.15% bupivacaine was studied with the purpose of minimizing hemodynamic changes, limiting the cephalad dispersion of the anesthetic and promoting a faster recovery. ⋯ Hypobaric bupivacaine (5 mg) is able to provide a predominant unilateral block with the patient being kept twenty minutes in the lateral position. Major unilateral spinal anesthesia advantage is hemodynamic stability.

Inhalational anesthetics analyzer as a method to detect anesthesia machine failures and prevent intraoperative awareness. Case report.
Although rare, intraoperative awareness is a severe general anesthesia complication. Anesthesia machine malfunction is one of several causes for anesthetic complications, among them intraoperative awareness. This report aimed at showing a case where the volatile anesthetic monitor has detected machine malfunction which could have led to intraoperative awareness. ⋯ Although rare, intraoperative awareness is a severe complication which should be prevented. Routine and thorough anesthesia equipment inspection before its use may minimize failures. The inhalational anesthetics monitor is useful whenever inhaled anesthetics are being used and may early detect anesthesia machine failures as in this case report.

There are reports on epidural blood patch in Jehovah's Witness patients using a closed system which allows blood collection and epidural injection without loss of continuity. This report aimed at presenting two cases of Jehovah's Witness patients with post-dural puncture headache and treated with epidural blood patch in a closed venous blood transfusion system to the epidural space. Cases were reported by two different hospitals in two different cities. ⋯ In Jehovah's Witness patients refractory to clinical treatment, autologous blood injection may be performed through the above-described technique after patients informed consent.

Analgesia and sedation with epidural clonidine associated to 0.75% ropivacaine in the postoperative period of open cholecystectomy.
Epidural clonidine has analgesic properties and potentiates local anesthetic effects; there are, however, some side effects including: arterial hypotension, bradycardia and sedation. This study aimed at evaluating analgesia and sedation of clonidine associated to 0.75% ropivacaine in the postoperative period of open cholecystectomy. ⋯ The association of clonidine and ropivacaine has produced longer analgesia and sedation at 2 and 6 hours of observation.

Hemorrhagic shock hemodynamic and metabolic behavior: experimental study in dogs.
Different experimental models have been used to illustrate hemodynamic and metabolic changes during hemorrhagic shock. This study aimed at observing hemodynamic and metabolic behaviors during a sequential and progressive model of hemorrhagic shock in dogs to determine which indices are earlier changed. ⋯ Mean blood pressure, heart rate, central venous pressure and pulmonary capillary pressure have not reflected real volume status of dogs in our experimental model, oxygen transport, consumption and extraction rate are useful parameters to determine hemorrhagic shock reversibility and prognosis.
