Comparative Study
[Features of the spinal cord injury in distractive flexion and compressive extension cervical spine trauma].
1) to assess neurological status in patients with distractive flexion and compressive extension cervical spine injuries; 2) to determine the relationship between neurological recovery and the patterns of cervical spine injuries. ⋯ Neurological status of the patients with distractive flexion and compressive extension cervical spine injuries did not differ. The relationship between neurological recovery and the patterns of cervical spine injuries did not exist.

Randomized Controlled Trial Clinical Trial
[Bupivacaine for continuous interscalene brachial plexus analgesia after shoulder surgery].
This study evaluates clinical efficacy of continuous interscalene brachial plexus block with bupivacaine 0.15% for postoperative analgesia after shoulder surgery. ⋯ Continuous interscalene brachial plexus analgesia is a reliable and effective method of providing postoperative pain relief after shoulder surgery and is superior to the systemic analgesia.

Review Comparative Study
[Perforated duodenal ulcer: benefits and risks of laparoscopic repair].
Laparoscopic perforated duodenal ulcer repair is a minimally invasive technique. Just like any other type of surgery, the laparoscopic approach carries operative risks in itself. The primary goal of this article is to describe the possible risk factors in laparoscopic duodenal ulcer repair. The secondary goal is to clarify benefits of the laparoscopic surgery. ⋯ Shock, delayed presentation (>24 hours), confounding medical condition, age >70 years, American Society of Anesthesiology III-IV degrees and Boey score--all above should be considered as preoperative laparoscopic repair risk factors. Inadequate ulcer localization, large perforation size (>6 mm diameter according to ones, >10 mm according to others) and ulcers with friable edges are also considered as laparoscopic repair risk factors: each of the factors independently is an indication for an open repair.

The aim of this study was to determine diagnosis and factors influencing acute respiratory failure and nosocomial pneumonia according to literature and clinical findings in critically ill patients. The term "respiratory failure" implies the inability to maintain either normal delivery of oxygen to tissues or normal removal of carbon dioxide from the tissues. ⋯ Failure of any step in this process can lead to respiratory failure. Long-term hypoxia causes ischemic changes and dysfunction of brain, heart, kidney, lungs and can worsen the outcome of disease or can cause higher mortality.

Comparative Study
Lethal outcomes in patients with symptomatic heart failure developed after Q-wave myocardial infarction.
The article analyses clinical characteristics and mortality of patients with symptomatic chronic heart failure following Q-wave myocardial infarction. During the study 224 patients (mean age 64.1+/-9.7) with symptomatic chronic heart failure and left ventricular ejection fraction <40% were followed-up for 1-5 years (on the average, 2.6+/-2.0 years). The majority of the studied patients had had anterior or anterior-lower Q-wave myocardial infarction (61.6% and 25.9%, respectively) and an identified Canadian function class II-IV angina pectoris (74.6%), and one-fifth of the patients (19.6%) had unstable angina pectoris. ⋯ The evaluation of Kaplan-Meier curves showed that total mortality resulting from the development of chronic heart failure symptoms and indications of chronic heart failure during the 1st year was 21.0%, during the 2nd year -40%, during the 3rd year -55.0%, during the 4th year -61.0%, and during the 5th year -65.0% the highest mortality was observed when left ventricular ejection fraction < or =20%, and age >75. The development of severe chronic heart failure resulted, on the average, after 1.5+/-1.1 years. It is obvious that symptomatic chronic heart failure caused by ischemic cardiomyopathy and marked left ventricular systolic dysfunction following Q-wave myocardial infarction is a rapidly progressing process conditioning high risk of lethal outcome within the period of several years.
