Randomized Controlled Trial Clinical Trial[Thoracic paravertebral blockade: postoperative analgesic effectiveness and plasma concentrations of bupivacaine].
To compare the analgesic efficacy of thoracic paravertebral blockade with that of endovenous morphine to measure the plasma levels of bupivacaine and to study the complications derived from both techniques in patients undergoing thoracic or abdominal surgery with unilateral incision. ⋯ Thoracic paravertebral blockade is a very effective postoperative analgesic technique and is superior to that of i.v. morphine in patients undergoing thoracic or unilateral abdominal surgery. Peak plasma levels were much lower than those considered as toxic complications of interest were observed. Therefore, this technique may be considered as an alternative to other blockades such as extradural, interpleural or intercostal.

Randomized Controlled Trial Comparative Study Clinical Trial[Intubation with propofol without neuromuscular blockade. Effect of premedication on fentanyl and lidocaine].
Laryngotracheal reflexes, and possibilities of intubations following anaesthetic induction with propofol, with or without premedication and without neuromuscular blockade were evaluated. Hemodynamic parameters were also measured. ⋯ The use of propofol without neuromuscular blockade is inadequate for intubation since laryngotracheal reflexes are not suppressed. Besides, propofol does not prevent hemodynamic reactions. Premedication with fentanyl and/or lidocaine improves the responses not sufficiently to safely perform intubation.

[Intracavitary electrocardiography. A useful method for checking the correct localization of central venous catheters].
A placement technique for central venous catheters (CVC) using the intracavitary electrocardiography (ICECG) as well as three different connection systems of the CVC to the electrocardiographic monitor are described. The aim of the present study was to evaluate the correct placement of the CVC by this technique with posterior radiologic confirmation being carried out. The study was undertaken in 30 patients connecting a CVC to a negative electrode of the standard lead II and the positive to the left leg. ⋯ In 2 patients (6.6%) a biphasic "P" wave was not obtained and an abnormal position of the CVC was radiologically demonstrated at surgery (one in the ipsilateral subclavian vein and the other had a ring within the right subclavian vein impeding progression). The mean time used in the performance of this technique was 220 +/- 40 s. It is concluded that intracavitary electrocardiography is a simple, easy to learn and perform technique which does not delay surgical procedure and it is a reliable method for placing the end of the CVC.
