Clinical Syndromes that usually require Laparotomy
Peritonitis Rupture of an Organ
- Perforation - Organ Rupture
o Ulcer: Peptic; Duodenal (commoner in H. pylori) o OBGYN: Ectopic pregnant
o Intestinal: Diverticulum; Appendix o GI: Spleen
o Organ: Gall bladder (advanced cholecystitis) o Vascular: Aorta
- Exam and Investigations - Signs of Rupture
o Pain: Tenderness ± rebound pain (Blumberg sign) o Shock: See table below

Estimating Blood Loss from Patient's Initial Presentation
Parameter Class I Class II Class III Class IV
Blood Loss <750 mL (<15 %) 750-1500 mL (15-30 %) 1500-2000 mL (30-40 %) >2000 mL (>40 %)
Pulse <100 BPM >100 BPM >120 BPM >140 BPM
BP ↔ ↔ ↓ ↓
Pulse Pressures ↔/↑ ↓ ↓ ↓
Respirations 14-20/min 20-30/min 30-40/min >35/min
Urine Output >20 mL/hr 20-30 mL/hr 5-15 mL/hr Negligible
Mental State Slightly anxious Anxious Confused Lethargic
Fluid to give Crystalloid crystalloid Crystalloid + Blood Crystalloid + Blood
Clinical Syndromes that may not require a Laparotomy
Local Peritonitis Colic
- Inflammation - Nature of Presentation
o Intestinal: Diverticulitis; Appendicitis o Muscles: Spasms leads to intermittent pain
o Organ: Cholecystitis; Salpingitis o Restless: Pain may also be full and constant
- Indications of Investigations - Locations affected
o USS/CT: Swelling; Swinging fever; ↑ WCC o GI: Gut; Bile Duct; Gallbladder
- Investigations Options o Urinary: Ureter
o XR: Peritonitis can induce localised ileus o OBGYN: Salpinx; Uterus
- Management Options
o Drainage: Cutaneous; Laparotomy
