Randomized Controlled Trial Comparative Study
Comparison of different anesthetic regimens in patients undergoing laparoscopic adjustable gastric banding operations: a prospective randomized trial.
Obesity is a multisystem disorder, particularly involving the respiratory and cardiovascular systems; therefore, a multidisciplinary approach is required. In spite of widespread performance of weight reduction (bariatric) surgeries, information regarding the anesthetic care of morbidly obese patients is scarce. The aim of this study was to compare the impact of fentanyl and remifentanil on the time of recovery, breathing parameters, and postoperative pain in morbidly obese patients undergoing laparoscopic adjustable gastric banding operations. ⋯ The time to extubation was shorter in the remifentanil group, but there was no significant difference in the time to discharge from the postanesthesia care unit. The recovery of respiratory parameters to the baseline values was better and faster in the remifentanil group. The intensity of postoperative pain was similar in both groups (VAS, <3) CONCLUSIONS: Remifentanil showed good analgesic properties during laparoscopic gastric banding surgery. Postanesthesia recovery and return of respiratory parameters to the baseline values was faster when remifentanil was used. Postoperative pain and the rate of opioid-induced side effects after analgesia with remifentanil were similar as after anesthesia with a longer acting opioid, fentanyl. Despite the problem widely discussed in literature about remifentanil-induced hyperalgesia, no cases of analgesic overconsumption were registered in our study.

The aim of this study was to evaluate and compare the biomechanical effects of locking reconstruction plate positioning on the osteosynthesis of clavicle midshaft simulated transverse fractures. ⋯ The superior plating osteosynthesis of simulated midshaft transverse clavicle fractures with the 7-hole 3.5-mm locking reconstruction plate had a significantly higher bending (from top to bottom) load to failure in comparison with the anteroinferior plating osteosynthesis of the clavicle with the identical implants. Clavicles plated with the 7-hole 3.5-mm locking reconstruction plate at the superior aspect exhibited a significantly greater biomechanical stability at a load of 40 N than those plated at the anteroinferior aspect.

OBJECTIVE. The aim of this study was to investigate the effects of bupropion sustained release (SR) on cognitive function, evaluated by event-related potentials (ERPs), in heavy tobacco smokers. MATERIAL AND METHODS. ⋯ The increases in the P3b and P2 amplitudes for target events in the parietal area are very suggestive of this hypothesis, since these components reflect the response to task-relevant target events. Meanwhile, the increased P2 latency for standard events may reflect reduced attention resources for the processing of standard events due to increased attention resources allocated for task-relevant target events. Decreased distractibility and increased attention are believed to be caused by bupropion.

Randomized Controlled Trial
Preliminary results of randomized controlled study on decompressive craniectomy in treatment of malignant middle cerebral artery stroke.
Studies on decompressive craniectomy (DCE) after a malignant middle cerebral artery (MCA) stroke in selected population show an increased probability of survival without increasing the number of very severely disabled. Cerebral infarct volume (CIV) as a triage criterion for performing surgery has not been discussed in literature. The aim of this study was to investigate the value of CIV and initial National Institutes of Health Stroke Scale (NIHHS) and Glasgow Coma Scale (GCS) scores as possible triage criteria in the surgical treatment of patients with "malignant" MCA stroke. ⋯ Decompressive surgery in the selected patients is likely to increase the probability of survival with a favorable outcome without increasing the number of severely disabled survivors. Patients with CIV of more than 390 cm(3) may be bad candidates for DCE, and the prognosis is likely to be bad regardless the treatment strategy. The initial NIHHS and GCS scores did not prove any prognostic value in outcome.

Pregnancy in a woman with pulmonary hypertension carries a prohibitively high risk of maternal mortality, and pregnancy is contraindicated in such patients. Some women decide to continue with their pregnancy despite being aware of possible fatal maternal outcome. The management of pulmonary hypertension in pregnancy is a challenge and requires a multiprofessional approach. We report the case of a patient with severe pulmonary hypertension, who successfully underwent elective cesarean section under epidural anesthesia at 38 weeks of gestation and discuss major issues associated with the obstetric and anesthetic management of pregnant patients with pulmonary hypertension.
