ABSTRACT
Diagnostic peritoneal lavage (DPL) is an accurate technique to diagnose abdominal visceral injury in blunt abdominal trauma. Four-quadrant abdominal paracentesis should be used routinely in all cases of blunt abdominal injuries as a diagnostic tool. The study included 50 cases in whom four-quadrant abdominal paracentesis was done at JN Medical College, Aligarh. There were 13 positive taps, out of which 12 were true positive and one was false positive. In all 37 negative taps DPL was done, out of which 23 had positive lavage, 22 had true positive and one had false negative results. All the patients with true positive peritoneal lavage had intra-abdominal injuries at laparotomy.

Acid base changes are common in surgical patients. The present study was conducted in 50 seriously ill surgical patients over a period of 56 hours. A wide range of pH was observed with 72% observations outside the normal limits. Alkalosis was observed in 44% of total observations while acidosis was noted in 28%. A higher mortality was seen in cases with alkalosis.
