What is the difference between a scrub nurse and a circulating nurse?

The scrub nurse is part of the sterile team, directly assisting the surgeon by handing instruments, managing swabs, and maintaining the sterile field. The circulating nurse works outside the sterile field, fetching supplies, documenting, and monitoring the patient's anaesthesia. Both roles are critical for efficient and safe surgery.

How do I choose the correct suture material for a wound?

Selection depends on the tissue type, wound tension, healing time, and infection risk. Absorbable sutures (e.g., polydioxanone) are used for internal layers, while non-absorbable (e.g., nylon) are for skin. Monofilament sutures cause less tissue reaction than braided ones. Always consider the patient's species and any allergies.

What are the signs of postoperative haemorrhage?

Signs include tachycardia, pale mucous membranes, prolonged capillary refill time, hypotension, and visible blood loss from the incision or drains. The animal may be restless or collapse. Immediate action includes applying pressure, fluid resuscitation, and notifying the veterinary surgeon.

How often should surgical instruments be sterilised?

Instruments must be sterilised after every use, even if they appear clean. Between patients, they undergo cleaning, inspection, and sterilisation (usually autoclaving). If a sterile pack is opened but not used, it should be re-sterilised unless it remains sealed and undamaged.

What is the role of a veterinary nurse during anaesthetic recovery?

The nurse monitors vital signs (heart rate, respiratory rate, temperature, oxygen saturation), ensures a quiet environment, administers analgesia as prescribed, and checks for complications like hypothermia or airway obstruction. They also provide supportive care such as turning the patient and offering food when appropriate.

Why is it important to use a surgical checklist?

Checklists reduce errors by ensuring all steps are completed, such as patient identification, consent verification, instrument counts, and antibiotic administration. They improve team communication and standardise care, leading to better patient outcomes and fewer adverse events.

Instrumentation and Sterilisation

VETSKILL

vocational

This subtopic addresses the critical competencies required for a veterinary nurse in surgical settings, focusing on the identification, selection, and safe use of a diverse range of surgical instruments. It also covers sterilisation methods essential for infection control, as well as the standardised protocols for cleaning, care, and maintenance to prolong instrument life and ensure patient safety.

VetSkill Level 5 Advanced Diploma in Veterinary Nursing (Surgical)

Topic Overview

The VetSkill Level 5 Advanced Diploma in Veterinary Nursing (Surgical) module focuses on the perioperative care of surgical patients, covering the entire surgical journey from preoperative assessment to postoperative recovery. This includes understanding aseptic technique, surgical instrumentation, anaesthesia monitoring, and wound management. Mastery of this module is essential for veterinary nurses to ensure patient safety, reduce surgical complications, and support veterinary surgeons effectively in a clinical setting.

This module builds on foundational knowledge of anatomy, physiology, and infection control. It integrates practical skills such as preparing the surgical environment, assisting during procedures, and providing critical postoperative care. Students will learn to anticipate the needs of the surgical team, manage emergencies, and apply evidence-based protocols to optimise patient outcomes. The content aligns with the Royal College of Veterinary Surgeons (RCVS) Day One Competences for veterinary nurses.

Understanding surgical nursing is vital for career progression in veterinary practice, as it represents a core area of responsibility for qualified veterinary nurses. This module not only prepares students for the VetSkill assessments but also equips them with the confidence to handle complex surgical cases, from routine neutering to advanced orthopaedic or soft tissue surgeries.

Key Concepts

Core ideas you must understand for this topic

→Aseptic technique: Principles of maintaining a sterile field, including surgical hand preparation, gowning, gloving, and draping to prevent surgical site infections.
→Surgical instrumentation: Identification, handling, and care of common instruments (e.g., scalpel, forceps, scissors, needle holders) and understanding their uses in different procedures.
→Anaesthesia monitoring: Use of equipment like pulse oximeters, capnographs, and blood pressure monitors; recognising stages of anaesthesia and responding to changes in vital parameters.
→Wound healing and management: Phases of healing (inflammatory, proliferative, remodelling), factors affecting healing, and appropriate dressing selection and application.
→Perioperative nursing care: Preoperative assessment (e.g., fasting, consent), intraoperative assistance (e.g., haemostasis, tissue handling), and postoperative care (e.g., pain management, monitoring for complications).

Learning Objectives

What you need to know and understand

1. Understand the use of a wide range of surgical instruments.2. Understand the methods of sterilisation for a range of surgical equipment.3. Understand standard operating procedures for the cleaning, care and maintenance of surgical instruments.

Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for demonstrating accurate identification and classification of surgical instruments (e.g., haemostatic forceps, tissue forceps, needle holders) and providing a rationale for their selection according to the surgical procedure.
Award credit for explaining the principles of steam autoclaving, including critical parameters of temperature (e.g., 134°C), pressure, and cycle duration, and for comparing alternative sterilisation methods such as ethylene oxide or hydrogen peroxide plasma for heat-sensitive equipment.
Award credit for describing the full standard operating procedure for instrument cleaning and decontamination, including manual pre-cleaning, ultrasonic bath usage, inspection for function and damage, lubrication of box joints, and appropriate packaging for sterilisation and storage.

Assessment Guidance

Guidance for achieving higher grades

💡During practical assessments, verbalise each step of the cleaning and sterilisation process to evidence your comprehension of infection control rationales.
💡When answering written or oral questions on sterilisation, always include monitoring methods such as chemical indicator strips, Bowie-Dick tests, and biological spore indicators to demonstrate a thorough understanding of quality assurance.
💡Be prepared to troubleshoot common instrument faults, such as stiff joints or misaligned ratchets, and discuss corrective actions like relubrication or removal from service, showing proactive maintenance awareness.
💡In exams, always justify your choice of surgical instruments or dressings by linking to the specific procedure or wound type. For example, explain why a swaged-on needle is preferred for vascular surgery.
💡When answering questions on aseptic technique, mention the importance of 'no-touch' technique and the sequence of gowning and gloving to demonstrate understanding of infection control hierarchy.
💡For anaesthesia monitoring questions, include specific parameters (e.g., end-tidal CO2 35-45 mmHg, SpO2 >95%) and explain how you would respond to abnormal readings, showing clinical reasoning.

Common Mistakes

Common errors to avoid in your coursework

Confusing similar-looking instruments, such as Spencer Wells forceps with Halsted mosquito forceps, or misidentifying tissue forceps (e.g., Adson versus rat-tooth).
Overlooking the importance of immediate rinsing and soaking of instruments post-surgery to prevent blood and tissue drying, leading to corrosion or ineffective sterilisation.
Assuming all surgical instruments can withstand steam autoclaving without checking manufacturer guidelines, resulting in damage to delicate ophthalmic or powered instruments.
Misconception: Sterile gloves are only needed for the surgeon. Correction: All personnel in the sterile field, including the scrub nurse, must wear sterile gloves to maintain asepsis and prevent contamination.
Misconception: A patient can be fasted for too long without risk. Correction: Prolonged fasting can lead to hypoglycaemia, dehydration, and stress, especially in small or young animals. Follow species-specific guidelines (e.g., 4-6 hours for small mammals).
Misconception: Postoperative pain is obvious and easy to assess. Correction: Animals often mask pain; use validated pain scoring systems (e.g., Glasgow Composite Measure Pain Scale) and monitor subtle signs like changes in behaviour, posture, or appetite.
