NCBI Bookshelf. Hajira Basit ; Gordon J. Ruan ; Sandeep Mukherjee. Authors Hajira Basit ; Gordon J. Ruan 1 ; Sandeep Mukherjee 2. The original Ranson's criteria is a scoring system that uses 11 parameters to assess the severity of acute pancreatitis. The 11 parameters are age, white blood cell count WBC , blood glucose, serum aspartate transaminase AST , serum lactate dehydrogenase LDH , serum calcium, fall in hematocrit, arterial oxygen PaO2 , blood urea nitrogen BUN , base deficit, and sequestration of fluids.

The criteria are named after Dr. John Ranson, a surgeon and leading figure on the pancreas during the 20th century. Ranson introduced the criteria in his paper: Prognostic signs and the role of operative management in acute pancreatitis. The study had a population of patients with acute pancreatitis. Eleven objective findings were determined to be of significant prognostic value for predicting severe acute pancreatitis. These objective findings are the 11 parameters mentioned above that makeup Ranson's criteria.

It should be noted that there is also a modified Ranson's criteria. The criteria with 11 parameters are used to score alcoholic pancreatitis while the modified criteria have 10 parameters that are used to score gallbladder pancreatitis. Ranson's criteria are one of the earliest scoring systems to assess the severity of acute pancreatitis and continue to be widely used.

Since its inception, there are at least 17 other scoring systems that have been validated. Ranson's criteria are used to predict severity and mortality of acute pancreatitis. The modified criteria have a max score of Five parameters assessed on admission and the other 5 at the hour mark.

The criteria with 11 parameters are used to assess the severity of alcoholic pancreatitis. The modified Ranson's criteria are used to assess gallstone pancreatitis.

At 48 hours, the remaining 5 parameters are serum calcium less than 8. In this same meta-analysis, other scoring systems had better sensitivity or specificity.

Ranson et al. This limits its utility in time-sensitive situations like the emergency department. The third limitation is that the study group in Ranson et al. As a result, Ranson's criteria cannot be used for a pediatric or adolescent population. This was studied in Lautz et al. A Ranson score of 0 or 1 predicts that complications will not develop and that mortality will be negligible. A score of 3 or greater predicts severe acute pancreatitis and possible mortality. Severe acute pancreatitis is defined by the presence of any organ failure or local pancreatic complications such as pseudocyst, abscess, or necrosis.

Because of the drawbacks of the Ranson criteria, other factors are also used to assess the severity of acute pancreatitis. It is believed that the elevated BUN is a reflection of intravascular volume depletion, which is mediated by inflammatory mediators in response to the acute inflammation. The APACHE score has one major advantage over Ranson criteria in that it can be used to evaluate the patient at any time point of admission.

The one laboratory parameter which is often used to stage acute pancreatitis is the hematocrit. Other markers also used to stage acute pancreatitis include levels of CRP and interleukin Many other biological markers have shown promise in predicting the severity of acute pancreatitis e.

It is important to understand that imaging is not indicated to assess a patient with mild acute pancreatitis unless the patient is suspected of having a malignancy. However, CT scan of the abdomen is always indicated in patients with severe acute pancreatitis and is the imaging modality of choice in patients with complications. The CT scan is rarely needed within the first three days of admission unless the diagnosis is in doubt because most inflammatory alterations are often not visible on the scan at this time.

The Ranson criteria have been used to assess the severity of acute pancreatitis for several decades. There continues to be argument about its sensitivity and specificity. However, it is vital that patients with acute pancreatitis be assessed by an interprofessional team that includes a gastroenterologist, surgeon, endocrinologist and a radiologist. Patients with moderate to severe acute pancreatitis are best monitored by ICU nurses.

There are other scoring criteria that can also be used to assess the severity of the condition. One should not place reliance on Ranson criteria but also use clinical acumen.

Ranson criteria

Corelation among clinical, biochemical and tomographic criteria in order to evaluate the severity in acute pancreatitis. Palabras clave: Pancreatitis aguda. Background: the acute pancreatitis is an inflammatory process that may involve peripancreatic tissue and distant organs. There exist few studies that correlate these parameters. Objective: to evaluate the severity of the acute pancreatitis according to the Ranson, APACHE-II and serous hematocrit criteria at the moment of admission of the patient and correlate these scales with the local pancreatic complications according to the Balthazar classification.
