Develop a Novel Nomogram to Predict Respiratory Failure in Acute Pancreatitis at Early Stage
Background:
Respiratory failure is a common complication in patients suffering from moderately severe or severe acute pancreatitis (AP). The aim of this study was to develop a novel nomogram to predict respiratory failure in AP early.
Methods:
Patients, who were hospitalized within 72 hours of AP onset from January 1, 2018, to April 31, 2021 were enrolled in the study. The patients were divided into two groups including respiratory failure group and no respiratory failure group. The demographic characteristics and laboratory parameters were compared between the two groups. A nomogram was established with stepwise logistic regression and "rms" packages of R software.
Results:
A total of 190 patients were finally included. White blood count, hemoglobin, sodium and calcium were significantly different between the two groups (all p < 0.05). White blood count (odds ratio [OR] = 1.28, 95% confidence interval [CI]: 1.14 - 1.47, p < 0.001), lymphocyte count (OR = 2.92, 95% CI: 1.16 - 7.70, p = 0.023), albumin (OR = 1.15, 95% CI: 1.01 - 1.33, p = 0.045) and calcium (OR = 0.00, 95% CI: 0.00 - 0.01, p < 0.001) were independent risk factors for respiratory failure in AP patients. After stepwise logistic regression was applied, white blood count, albumin, and calcium were used for the construction of the nomogram. The area under the curve (AUC) of the nomogram for respiratory failure was 0.832, which was higher than the BISAP score, and the nomogram possessed high concordance as calibration curves showed.
Conclusions:
The nomogram could predict respiratory failure in AP at an early stage with high accuracy.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Acute Respiratory Failure-V

Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Respiratory Failure-III
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
