Clinical TrialIncidence of gastrointestinal complications in cardiopulmonary bypass patients.
Gastrointestinal complications after cardiac surgery are associated with a high mortality rate. Because of the absence of early specific clinical signs, diagnosis is often delayed. The present study seeks to determine predictive risk factors for subsequent gastrointestinal complications after cardiosurgical procedures. ⋯ Furthermore, cardiopulmonary bypass and aortic clamping times were significantly prolonged in patients who developed gastrointestinal complications. A number of predictive factors contribute to the development of gastrointestinal complications after cardiopulmonary bypass surgery. Knowledge of these factors may lead to earlier identification of patients at increased risk and may allow more efficient and earlier interventions to reduce mortality.

The incidence of head and spinal injury is on the rise in developing countries. The number of deaths and burden of disability may be reduced, if not completely stopped, through preventive measures after an epidemiological survey on trauma. The goal can be achieved to a significant extent through the use of guidelines from the countries that have achieved a reduction in the incidence of neurotrauma. ⋯ British Medical Research Council Scale was used for assessment of motor power of patients with spinal trauma. Of these, 780 patients (29%) had complete spinal cord injury. Surgical intervention was performed in 1800 patients (68%) and the rest were managed conservatively.

Thoracic and thoracoabdominal penetrating wounds are frequently encountered in urban medical centers in the United States. This study was undertaken to determine the clinical characteristics and in hospital outcome of these injuries. This was a longitudinal, nonblinded study using the established standard of care of patients with penetrating chest trauma. ⋯ More than one-third of the patients with transaxial wounds die. Gunshot wounds of the heart result in higher mortality than stab wounds to the heart. The infection rate is low.

Surgeon's occupational exposure to nitrous oxide and sevoflurane during pediatric surgery.
Health hazards from occupational exposure to trace concentrations of anaesthetic gases cannot be definitively excluded. The aim of the study was to determine the surgeon's occupational exposure to nitrous oxide and sevoflurane during pediatric surgical procedures. Twenty young children (age < 10 years) and five teenagers (age > 10 years) underwent elective abdominal surgery under general inhalational anesthesia. ⋯ General anesthesia results in operating room air pollution with inhalational anesthetics. Under modern air conditioning, personnel's occupational exposure is low, and inhalational anesthesia is safe from the standpoint of modern workplace laws and health care regulations. Nonetheless, all efforts must be taken to maintain occupational exposure at this low level.

Randomized Controlled Trial Comparative Study Clinical TrialLactate metabolism during laparoscopic cholecystectomy: comparison between CO2 pneumoperitoneum and abdominal wall retraction.
Recent reports have implicated CO2 pneumoperitoneum for laparoscopic surgery in the occurrence of postoperative mesenteric ischemia. With this kind of surgery, the increase in blood lactate levels has been attributed to anaerobic metabolism, probably due to tissue ischemia induced by high intraabdominal pressure (IAP). The aim of this study was to evaluate the metabolic repercussion of CO2 pneumoperitoneum during laparoscopic cholecystectomy (LC). ⋯ Lactate concentration, expressed as mean (SD), went from 25.4 (14.4) mg/dl at baseline to 18.9 (13.6) mg/dl 4 hours after surgery in the PP group and from 19.4 (6.1) mg/dl at baseline to 17.8 (14.7) mg/dl in the AWR group. No significant differences were found between groups intraoperatively (p = 0.116) or postoperatively (p = 0.99). Our study did not show significant differences in blood lactate levels during LC with CO2 pneumoperitoneum compared to the same procedure with abdominal wall retraction.
