A modified technique of orthotopic transplant of the kidney in rabbits
In this study kidneys were harvested from bred-for-research cats weighing 4 to 5 kg. General principles of donor bilateral nephrectomy en bloc with aorta, vena cava, renal vessels, and ureters were followed. After the harvest the grafts were placed in lactated Ringer slush. A cuff was prepared on the renal vein over a 10 French plastic tube. The aorta was divided and left in connection with the renal artery at each side. Twenty female checkered Flemish giant rabbits weighing 4.0-6.0 kg served as recipients. After premedication with 40 mg/kg of ketamine, anesthesia was maintained with repeated doses (every 10-15 min) of a 0.1-mL mixture of 5 parts ketamine and 1 part acepromazine diluted 50% in a normal saline. Arterial pressure, CVP, blood gases, and temperature were monitored. Through a limited midline incision a native left nephrectomy was performed. The venous anastomosis was performed with a cuff technique without clamping the vena cava (which causes severe hemodynamic instability); the anastomotic time was 2-3 min. The arterial anastomosis was performed with an end-to-side aorta-to-aorta anastomosis; the anastomotic time was 5 to 7 min. There were no episodes of venous or arterial thrombosis. The donor procedure took approximately 40 min, and the backtable preparation of the graft an additional 45 to 60 min. Preparation of the recipient for the anastomosis took 15 min and the anastomotic time (warm ischemia) was 13 +/- 5 min. In this model suitable for xenograft research the duration of the surgery in the recipient has been greatly reduced because of (1) the previous backtable preparation of the graft, and (2) the cuff technique used for venous anastomosis. The present anesthesia regimen and careful hemodynamic monitoring were also important in the success of this model

[Artificial nutrition in the injured patient]
Current knowledge of physiopathology allows better understanding of the metabolic and immunological alterations that occur after trauma, thus allowing more adequate treatment. Nutritional support is recognized as an important therapeutic intervention to promote wound healing, reduce the risk of infection and improve survival. The patient with severe trauma needs nutritional support from the beginning of treatment. The early administration of enteral nutrition is an important factor in the reduction of gut bacterial translocation and thus of septic complications. In the early phase, the parenteral route is capable of providing a sufficient calorific and protein support, whilst awaiting the recovery of the enteral route

[Traumatic perforation of the duodenum. Diagnostic and therapeutic problems]
The treatment of traumatic ruptures of the duodenum is one of the greatest controversies in surgery. The injury mechanisms, diagnostic criteria and factors underlying the prognosis are analysed and indications suggested for the various types of intervention. The problem relating to the operating technique are specified
