Day 2 after laparotomy: reading the early warning signs
Mr K., 58 years old, is on the second evening after an emergency laparotomy for a perforated appendix in a district hospital. He has an intravenous line in the right forearm, a urinary catheter, and a corrugated rubber drain in the right iliac fossa. At 6 p.m. the staff nurse records: temperature 38.4 °C, pulse 104/min and thready, respirations 24/min, blood pressure 106/64 mmHg. The drain has soaked one abdominal pad with serosanguineous fluid in the past 4 hours; urine output was 20 mL, 15 mL and 20 mL in the last three hours. He weighs 60 kg. He lies still and refuses to turn, saying the pain is unbearable, and asks for an injection. The surgeon is attending a call 20 minutes away. The ward has paracetamol tablets and the prescribed 8 p.m. dose of intravenous cefotaxime is due now. A first-year student asks whether they should simply wait for the surgeon.
1. Which of these observations are abnormal, and what pattern do they form? Rank your concerns.

Abnormal findings
- Temperature 38.4 °C - above the normal 36.5–37.5 °C.
- Pulse 104/min, thready - tachycardia with poor volume.
- Respirations 24/min - tachypnoea.
- BP 106/64 mmHg - systolic is low-normal, but the pulse pressure is only 42 mmHg and has to be read together with the tachycardia; a young adult may hold his systolic pressure while compensating.
- Urine output 15–20 mL/hour - below the minimum of 0.5 mL/kg/hour, which for 60 kg is 30 mL/hour.
- One soaked drain pad in 4 hours - more than the serosanguineous seepage expected on day 2.
Pattern and ranking
- Circulation first - tachycardia, narrowing pulse pressure and oliguria together suggest falling circulating volume (bleeding or third-space loss) and early septic shock. Urine output is the most sensitive bedside index of renal perfusion, so it carries more weight than the single BP reading.
- Drain and wound - quantify the loss and check for fresh bleeding.
- Temperature - supports infection but fever alone does not explain the oliguria.
- Pain and immobility - a real risk for atelectasis and deep vein thrombosis, but not the immediate threat to life.
Reasoning: no single value is alarming in isolation; the pattern of compensation followed by oliguria is what makes this a developing shock picture. Waiting for the surgeon without acting wastes the window in which simple measures work.
2. What will you do in the next 30 minutes, before the surgeon arrives? Include what you will record, what you will not do, and what you will report.

Assess and stabilise
- Repeat vital signs, check capillary refill, consciousness, and the IV site for patency and rate.
- Inspect the drain, pad, wound and catheter; empty and measure the urine bag yourself rather than relying on the chart.
- Position him semi-Fowler for breathing if BP allows; keep the legs level if he feels giddy. Do not leave him alone.
- Give the prescribed cefotaxime at 8 p.m. on time; give paracetamol as prescribed for pain, but record the temperature before the dose.
Record
- Time-stamped vital signs, exact drain and urine volumes, fluid intake, the fact that the patient refused to turn, and the analgesia given.
Report now, not later
- Telephone the surgeon with a structured report: patient, day 2 laparotomy, pulse 104, BP 106/64, urine 20 mL/hour for three hours, temperature 38.4 °C, drain soaked, asking for instructions on fluids, blood grouping and review.
Do not
- Do not give extra analgesics or start or increase IV fluids without an order; do not remove the drain; do not chart observations you did not take.
Reasoning: the nursing role here is detection, accurate data and escalation in parallel - not waiting for permission to notice deterioration.
3. The student suggests withholding the 8 p.m. antibiotic until the doctor sees the patient, so that 'the fever is not hidden'. Give your reasoned response.
Read the worked answer
Give the antibiotic on time.
- Clinical reason: in a patient with a likely intra-abdominal source and early sepsis, the antibiotic is time-critical; every hour of delay is associated with worse outcomes. The fever is a marker, not the disease, and the surgeon will treat the patient, not the thermometer reading.
- Practical reason: the temperature has already been recorded and further readings will be taken; nothing is hidden. The pattern of pulse, respiration, urine output and drain loss is more informative than fever alone and remains fully visible.
- Professional and legal reason: the nurse administers prescribed treatment and does not independently alter or withhold it. Withholding a prescribed drug is a deviation from the care plan and, if harm follows, exposes the nurse to professional and legal consequences. If a genuine contraindication appears, the correct route is to contact the prescriber and obtain a written order to hold the dose, not to decide alone.
- Stewardship: unnecessary or delayed antibiotics both cause harm; the answer is prompt prescribed therapy plus culture specimens if ordered, not ad hoc changes.
Action: give the dose at 8 p.m., record the time and the pre-dose temperature, continue half-hourly to hourly observations, and state in the nurses' notes what was given and when the surgeon was informed.
