Randomized Controlled Trial Comparative Study
Usage of GreenLight HPS 180-W laser vaporisation for treatment of benign prostatic hyperplasia.
Laser therapy has gained increasing acceptance as a relatively less invasive treatment for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). From the early procedure of interstitial laser coagulation through to the use of holmium laser enucleation of the prostate, there has been an expanding body of evidence on the efficacy of such procedures. One of the newer lasers is the Green Light HPS 180 W laser. Studies with this GreenLight laser (GLL) (American Medical Systems, Inc, Minnetonka, MN, USA) showing results as good as those of transurethral resection of the prostate (TURP). In this paper, the efficacy of the new GLL 180-W versus the gold standard TURP in patients with LUTS due to BPH was tested in a prospective clinical trial. ⋯ Compared to transurethral resection of the prostate, GreenLight HPS 180-W laser photoselective vaporization of the prostate is safe and effective in the treatment of patients suffering from lower urinary tract symptoms due to benign prostatic hyperplasia.

Randomized Controlled Trial
[Hemodynamic effect of local infiltrative 2% lidocaine adrenaline anesthesia in general balanced anesthesia during middle ear surgery].
Hemodynamic effect of different techniques and type of anesthesia are defined. The volume of reduced hemorrhage in surgical field is debatable, without any definite conclusion. The objective of the study is to investigate the effects of local infiltrative anesthesia with adrenaline during general balanced anesthesia and nitroglicerol on blood presure and hemorrhage reduction in middle ear operations. ⋯ Blood pressure and heart rate was not different between the two groups. But, intraoperatively, the study showed lowering of sistolic and diastolic blood pressure. This mode of treatment and surgeon's verbal reply confirmed that local infiltrative anesthesia with adrenaline under balanced anesthesia had no effect on hemorrhage reductionin surgical field.

Randomized Controlled Trial
Does epidural anaesthesia and analgesia really improves surgical outcome after colorectal cancer surgery?
Lithuanian Cancer Register has registered 1443 new cases of colorectal cancer in 2004 and this value constantly increases about 200 cases per year. Colorectal cancer is on the third place among all cancer patients in our country. ⋯ Majority of recent randomized clinical trials (RCT) has shown that combined general--epidural anaesthesia and postoperative epidural analgesia has demonstrated some beneficial effects and improved surgical outcome in various fields of surgery. However controversies still exist about epidural anaesthesia and analgesia effects on colorectal anastomosis and it's influence on patients' outcome.

Randomized Controlled Trial Clinical Trial
[Epidural analgesia in total gastrectomy--combination of bupivacaine with ketamine or fentanyl].
The effects of intraoperative epidural administration of ketamine added to bupivacaine were compared with fentanyl added to bupivacaine in patients undergoing total gastrectomy. Prospective, randomized, double blind study was designed to compare: group F: 20 patients (pts) receiving 20 ml of 0.125% bupivacaine and 50 ug of fentanyl and group K: 20 pts in whom 20 ml of 0.125% bupivacaine was combined with 50 mg of ketamine. Pts received an epidural injection through peridural catheter introduced through either T7-8 or T8-9 interspinous space. ⋯ None of the pts complained of bad dreams or awakeness during operation. Both fentanyl and ketamine added to bupivacaine and given as a bolus provided good intraoperative analgesia in combination with general anaesthesia, minimal sensorimotor disturbance and early tracheal extubation. In our study fentanyl added to bupivacaine caused higher incidence of hypotension than ketamine added to bupivacaine.
