What is the difference between monopolar and bipolar electrosurgery in veterinary practice?

Monopolar electrosurgery uses a pencil electrode and a return (grounding) plate placed on the patient's skin; current passes through the patient's body between the two points. Bipolar electrosurgery uses forceps where both electrodes contact the tissue simultaneously; current passes only between the forceps tips. Bipolar is preferred for delicate tissue, near implants, and in patients where current passage through the body is contraindicated (cardiac pacemakers).

What lighting specification is required for a veterinary surgical suite?

A minimum of 40,000 lux at working distance is the recognised standard for a surgical overhead light. LED surgical lights are preferred for their consistent colour temperature, low heat output, and long service life. A dual-dome configuration eliminates residual shadow from the surgeon's head and hands and is strongly recommended for abdominal and thoracic procedures.

How should veterinary surgical instruments be maintained?

Inspect all instruments quarterly for function — blunt scissors, sprung haemostats and locked needle holders reduce efficiency and compromise technique. Clean instruments in enzymatic solution immediately after use, before contamination dries. Lubricate box joints and ratchets with instrument milk before autoclaving. Replace damaged instruments rather than continuing to use instruments that do not function correctly.
