A Word From Your Senior
The operation is one episode in surgical care. The deeper craft is selecting the right patient, indication, timing, team, and rescue plan, then recognising complications early.
The Surgical Decision
Ask whether surgery is curative, diagnostic, preventive, reconstructive, palliative, or a means of source control. Compare it with non-operative care and with no intervention. Urgency depends on physiology and time-sensitive loss of life, organ, limb, or function.
Valid consent is a conversation about diagnosis, material benefits and risks, reasonable alternatives, likely recovery, uncertainty, and the patient's values. Capacity is decision- and time-specific. Emergencies and substituted decision-making must follow law and policy.
Before, During, and After
Preoperative work includes optimisation, medication planning, anaesthetic assessment, thrombosis and infection prevention, blood-management planning, site verification, and anticipating postoperative destination.
Intraoperative safety depends on sterility, haemostasis, tissue respect, human factors, communication, counts, and a shared plan for unexpected findings. Minimally invasive surgery changes access and recovery; it does not remove bleeding, infection, visceral injury, conversion, or anaesthetic risk.
Postoperative review should interpret pain, pulse, pressure, temperature, respiratory status, urine output, wound/drains, gastrointestinal recovery, mobility, cognition, and laboratory trends together.
Bedside Case
A patient is tachycardic six hours after abdominal surgery. Do not dismiss this as pain without testing the assumption. Consider bleeding, hypovolaemia, sepsis, hypoxia, pulmonary embolism, myocardial injury, urinary retention, drug effect, withdrawal, and pain. Examine, review observations and fluid balance, inspect relevant outputs, escalate, investigate selectively, intervene, and reassess.
Accuracy Guardrails
- Normal early blood pressure or haemoglobin does not exclude acute bleeding.
- Prophylactic antibiotics do not compensate for poor asepsis or source control.
- Absence of fever does not exclude postoperative infection.
- Drains neither guarantee safety nor replace clinical review.
- Use the WHO Surgical Safety Checklist as a team process, not a tick-box ritual.
