Study Type
OBSERVATIONAL
Enrollment
225
P-POSSUM score's variables are divided into physiological parameters (age, cardiac, respiratory, ECG, systolic blood pressure, pulse rate, haemoglobin, leukocyte count, urea, sodium plasma, potassium plasma, and GCS) and operative parameters (operation type, number of procedures, operative blood loss, peritoneal contamination, malignancy status, CEPOD).
