RESUMO
BACKGROUND: Counting the sponges is an important step in surgical procedures. A miscount may impact the patient's health, and it also has legal implications for the surgeon. This is an experimental study evaluating radio-frequency technology used in the perioperative period to identify surgical sponges left in the peritoneal cavity of swine. METHODS: Radio-frequency labeled-disc identification tags were sewn into 40 surgical towels. Twenty labels had the ability to emit radio-frequency waves, and 20 labels were inert to radio-frequency identification. Twenty adult pigs that underwent laparotomy and randomly received two surgical sponges were scanned by a radio-frequency identification antenna. RESULTS: This method presented a positive predictive value of 100% and 100% specificity and sensitivity, as all of the tagged surgical sponges were detected. CONCLUSION: Radio-frequency identification has been proved to be a useful method for the identification of surgical sponges within the abdominal cavities of swine.
RESUMO
CONTEXT: The elevation of serum amylase and lipase are generally associated with pancreatic diseases. However they can be associated with different pathologies unrelated with amylase and lipase. CASE REPORT: This paper aims to report a case of a patient diagnosed with nonspecific hyperamylasemia and warn of this possibility in the differentiation of hyperamylasemia. CONCLUSION: The correct diagnosis of silent hyperamylasemia is important in order to determine whether there is the risk of pancreatic disease or if we are just ahead of a benign hyperenzymemia.
